HealthCare Reform in the United States Research Proposal - 1

HealthCare Reform in the United States - Research Proposal Example Based on the study conducted by the Pacific Institute on Research and Evaluation (PIRE) in 1999, almost 3,500 deaths are caused by drinkers of below the age of twenty one every year (STATS, 2005). In fact, the Ministerial Council on Drug Strategy (2001) reports that approximately 70% to 80% of road accidents occur due to alcohol consumption amongst youngsters below the age of 25. Thus, evaluation needs to be conducted to review the existing policies and come up with sound measures that would cut across the policy criteria effectively to address the teen drunk-driving fatalities problem. According to the Ministerial Council on Drug Strategy (2001), alcohol product pricing has an effect on the rates of the consumption of alcohol in the society. Studies have demystified that if all other factors are held constant, alcohol price increase in general results in a decrease in alcohol consumption, and the opposite is true. The regimes of taxation are a platform from which alcohol price can be influenced. Most governments use their political autocracy for raising revenue to fulfil its goals of protecting the freedom and wellbeing of the citizens. Generally, the revenue comes from taxes. Alcohol is a significant source for raising government revenue in most countries. The benefits of increasing taxation on alcoholic beverages lie on the basis of public health view. Taxing alcohol as a measure of policy is relatively elementary and acceptable by the government who obtain revenue from it to fulfil its mandate of satisfying public needs. Through making the alcoholic drinks more expensive, there would be a decrease in per capita consumption and this would in turn reduce the problems associated with it. From a public health perspective, taxing alcoholic drinks would prevent both social and health problems and minimize alcohol-based burden on society. Thus, aside from just curbing drunk-driving

To Lie on the Bottom Essay There is a reason that World War II and the Holocaust are considered turning points in human history, a point from which everything changed: philosophy, art, music, film, architecture, politics, history, even the very concept of humanity was altered in an often imperceptible way. Something in us died; extinguished by a darkness so all-encompassing and cold that all hope and beauty and reason and love could not survive it, nothing could, not even God himself. This darkness, this ephemeral force worse than death eventually destroyed Primo Levi, but what it couldn’t destroy, was his soul. His soul witnessed and suffered something worse than death, â€Å"a journey towards nothingness, a journey down there, towards the bottom†(Levi, 17) and this tale from the very bottom of hell showed us a side of man never before seen. Dante’s Inferno where there is no God or heaven or right or wrong, but only hunger and despair. A moral hierarchy envisaged by the masterminds of the Final Solution, a cold, remorseless world where the innocent are destroyed and the strong enslaved. A world guided by the â€Å"ferocious law which states: ‘to he that has, will be given; from he that has not, will be taken away’. †(88) The hierarchy of this realm is distant from the rest of humanity, a timeless realm devoid of any remnants of what has been or what is yet to be. A barren, flat, colorless landscape scarred by never-ending paths of metal and wood all leading into the maw of a churning, smoke belching monster marked with a grim, foreboding preface â€Å"Arbeit Macht Frei, work gives freedom†(22). This is Auschwitz, a place unlike anywhere else in the annals of human history, â€Å"This is hell. Today, in our times, hell must be like this. A huge, empty room: we are tired, standing on our feet, with a tap which drips while we cannot drink the water, and we wait for something which will certainly be terrible, and nothing happens and nothing continues to happen†(22). In a place where the old, the young, and the weak are swallowed into the night and are gone forever, in a godless place like this nothing is as it should be. At the top of this mad house lies the most depraved of all, for in this place the insane rule over the sane, and the cold, mechanical fist of the S. S. is law. An extension of the mad-man responsible for this place, they are hand-picked and forged into thoughtless, remorseless killing machines and entrusted with Hitler’s most important goal: the destruction of the Jew. Little is said about these brutal men, they are above the camp and therefore distant from it, the camp to them is merely their work place and â€Å"they behave with the calm assurance of people doing their normal duty of every day. † At times they speak to the prisoners like animals whipping them into attention â€Å"in that curt, barbaric barking of Germans in command which seem to give vent to a millennial anger†, but during the selections when they decide who lives or dies with the slightest glance they are indifferent and speak â€Å"in a subdued tone of voice, with faces of stone†¦ We had expected something more apocalyptic: they seemed simple police agents. It was disconcerting and disarming†(19). Levi would soon discover that despite their outward appearance, these cold agents of doom were the most apocalyptic men on earth entrusted with the unspeakable mission of the destruction of his people. Below the SS men in the next rung of hell resided the ‘Prominenz’, inhabitants of Block 7 in which no regular prisoner has ever entered, they were â€Å"the aristocracy, the internees holding the highest post†(32). Below them were the Reichsdeutsche, the Aryan Germans, and the Kapos â€Å"they were particularly pitiless, vigorous and inhuman individuals, installed (following an investiture by the SS command, which showed itself in such choices to possess satanic knowledge of human beings) in the posts of Kapos, Blockaltester, etc†(89). These individuals established the backbone of authority, doling out punishment with reckless abandon knowing in the back of their heads if they showed the slightest hesitancy or remorse they would be quickly disposed of. Below them resided the rest of the political prisoners and British POW’s who were given special privileges and leniency. Below them resided the Jewish prominents: a sad and notable human phenomenon†¦ if one offers a position of privilege to a few individuals in a state of slavery, exacting in exchange the betrayal of a natural solidarity with their comrades, there will certainly be someone who will accept†¦ When he is given command of a group of unfortunates, with the right of life or death over them, he will be cruel and tyrannical, because he will understand that if he is not sufficiently so, someone else, judged more suitable, will take over his post. Moreover, his capacity for hatred, unfulfilled in the direction of the oppressors, will double back, beyond all reason, on the oppressed; and he will only be satisfied when he has unloaded on to his underlings the injury received from above. (91) These Jewish prominents were particularly hated by Levi and his fellow Jews and this hatred only served to further distance themselves from the rest of the group. Abhorrent as it may seem to abandon your compatriots and become part of the hated ruling class of the camp; the need to survive overrode any moral dilemma, because â€Å"in the Lager things are different: here the struggle to survive is without respite, because everyone is desperately and ferociously alone. †(88) There is no good and evil here because if you are not a prominent you are only ‘the saved and the drowned’. The saved and the drowned are those at the very bottom of hell with nothing between them and gas chamber, only those deemed capable and fit even survive the first day, the others are exterminated immediately. Most who remain quickly succumb to the all-consuming hunger and exhaustion of the camp, â€Å"their life is short, but their number is endless; they, the Muselmanner, the drowned, form the backbone of the camp, an anonymous mass, continually renewed and always identical, of non-men who march and labour in silence, the divine spark dead within them, already too empty to really suffer†(90). They are the forgotten masses of victims, abandoned by the world to their fate and quickly forgotten; no one remembers their names or their faces for they were condemned by all of humanity to a fate worse than death. â€Å"Imagine a man who is deprived of everyone he loves†¦, his house, his habits, his clothes†¦ everything he possesses: he will be a hollow man, reduced to suffering and needs, forgetful of dignity and restraint, for he who loses all often easily loses himself†(27). It’s in this way the Germans destroyed the humanity of a people before killing them further. The drowned are those who are unable to adapt, they sink down deep until it is too late for in this place â€Å"to sink is the easiest of matters†(90). After their children, women, and parents have all been swallowed up and everything they possess stolen, most give up. â€Å"They follow the slope down to the bottom, like streams that run down to the sea†(90). The saved are the few that remain, the ones who still battle for salvation, who have thrown off all moral constraints that hold them back, resolved to fight â€Å"against the current; to battle every day and every hour against exhaustion, hunger, cold and the resulting inertia; to resist enemies and have no pity for one’s rivals; to sharpen one’s wits, build up one’s patience, strengthen one’s will-power. Or else, to throttle all dignity and kill all conscience, to climb down into the arena as a beast against other beasts, to let oneself be guided by those unsuspected subterranean forces which sustain families and individuals in cruel times†(92). Elias, Schepschel, Alfred L. , and Henri, four very different men, all struggling on the own path to salvation, all willing to do anything; they are not good men, for a good man means nothing in here, all the good men died a long time ago or at least ceased to be good, for only scoundrels remain now. The Germans in a sense created â€Å"a gigantic biological and social experiment†(87), an alien world like no other in history, stripped of all moral and ethical boundaries, all reason and justice destroyed, replaced with a twisted, sadistic existence of perceived order masking the uncontrolled debauchery of it all. From this horror only a few are blessed with the talents needed to survive, some like Elias have â€Å"survived the destruction from outside, because he is physically indestructible; he has resisted the annihilation from within because he is insane†¦ he is a survivor†¦ the human type most suited to this way of living(97)†¦ Henri, on the other hand, is eminently civilized and sane†¦ he is extremely intelligent, speaks French, German, English, and Russian†¦ is perfectly aware of his natural gifts and exploits them with the cold competence of a physic using a scientific instrument†¦ there is nothing in the camp that he does not know and about which he has not reasoned in his close and coherent manner†¦ hard and distant, enclosed in armour, the enemy of all, inhumanly cunning and incomprehensible like the Serpent in Genesis†(98-100) Elias and Henri are two sides of the same coin, one physically invincible the other mentally, the rare, extraordinary survivors of a biological experiment gone too far, perfectly molded for the hostile world created to destroy them. They are interesting only in the fact that they are the statistical anomalies of a mathematically-precise extermination process, one which inevitably would destroy even them. Most who survive are not so lucky, not naturally blessed with ability or strength, but simply scratch and claw their way out. They learn quickly, they learn a little German, begin to make alliances with those who have something to offer. They steal when they can, grabbing anything of value, anything that can be traded for in the ‘Exchange Market’, â€Å"where scores of prisoners driven desperate by hunger prowl around, with lips half-open and eyes gleaming, lured by a deceptive instinct to where the merchandise shown makes the gnawing of their stomachs more acute and their salvation more assiduous†(78). These exchanges are necessary to survive, for to try to live with just the meager sustenance given is impossible, the system was created to destroy them, only by breaking the rules can one hope to survive. Often the saved are assisted by civilian workers or gain the favor of a Prominent who provides them with extra food or clothing. One of the few people Primo Levi’s speaks kindly of in the entire book is such a person, a civilian worker named Lorenzo. I believe that it was really due to Lorenzo that I am alive today; and not so much for his material aid, as for his having constantly reminded me by his presence, by his natural and plain manner of being good, that there existed a just world outside our won, something and someone still pure and whole, not corrupt, not savage, extraneous to hatred and terror; something difficult to define, a remote possibility of good, but for which it was worth surviving. The personages in these pages are not men. Their humanity is buried, or they themselves have buried it†¦ The evil and insane SS men, the Kapos, the political, the criminals, the prominents, great and small, down to the indifferent slave Haftlinge, all the grades of the mad hierarchy created by the Germans paradoxically fraternized in a uniform internal desolation. But Lorenzo was a man; his humanity was pure and uncontaminated, he was outside this world of negation. Thanks to Lorenzo, I managed not forget that I myself was a man. (121-122) Lorenzo represents the last vestige of a better world, a glimpse of sanity and reason that seems to no longer exist. He reminded Levi that there still remained a world outside the Lager, where humanity endured; that someday this world would no longer exist and your life would continue, and all that was thought lost forever would be returned to you. The Holocaust was not decided upon with anger, but with a cold, calculating necessity, hell-bent on destroying every Jew on Earth, to extinguish an entire people. To the Germans the Jews were a disease, a parasitic organism, which required extermination. The Jews of America and England, the Jews of the Soviet Union and of Spain, the Jews of North Africa and the Middle East, they were all to be dealt with eventually. This is the mindset of the creators of this alien world. The depravity of the camp; its cruel, ordered madness reflected the depravity and evil that emanated from the souls of those wicked men. The SS were their finest pupils, there most willing executioners, those entrusted with the sacred task of the Nazi regime: the destruction of its enemies, a war against all of humanity. The morals and ethics of their creation were the ethics and morals of Hitler himself, of Reinhard Heydrich, of Adolf Eichmann, of Heinrich Himmler, of Rudolph Hess, the masterminds of this unparalleled killing machine. This is what Primo Levi experienced deep down in the belly of the beast, inside the heart of darkness. The orchestra of the camp that emanated it throughout its boundaries â€Å"the perceptible expression of its geometrical madness†(51), the driving force behind this choreography of the dead. The SS instilled the camp with their notorious character, driven by their remorseless zeal, controlled by their obsessive discipline. The camp is as much a reflection of them as they are a reflection of their creators, the men who molded them into hardened killing machines. The lack of morals apparent in the camp derives itself from the lack of morals apparent in the individuals who created and ran it. The moral codes and fundamental laws of the Lager are based on three basic assumptions which in accordance formed a deranged society: â€Å"the privileged oppress the unprivileged†(44) and â€Å"to he that has, will be given; from he that has not, will be taken away†(88), and most importantly the complete inferiority of the Jew. The Jew was nothing, the slaves of the slaves, and everyone acted to continually reaffirm this assertion. The Kapos, the Blockaltesters, the cooks, the nurses, everyone, even the Jewish prominents constantly reminded the Jews of their inferiority, every rule and regulation instilled it further. For many non-Jews this place is nothing but a prison, they lived in relative comfort with adequate food, clothing, and shelter. As soon as they enter they are made at ease for at least there are many much worse off than they; they are given special privileges and â€Å"are automatically invested with offices as they enter the camp in virtue of their natural supremacy†¦no ‘Aryan’ Haftling was without a post, however modest†(90-91). For them Auschwitz is but a prison, but to the Jew on the contrary, â€Å"the Lager is not a punishment; for us, no end is foreseen and the Lager is nothing but a manner of living assigned to us, without limits of time, in the bosom of the Germanic social organism†(82-83). This ‘manner of living assigned’ to the Jews has the effect of reducing them to their most basic needs, their dignity and integrity stripped from them. When Levi first arrived he is still a man, cognizant and alive, searching in the distance for his loved ones, â€Å"at the other end of the platform; then we saw nothing more. Instead, two groups of strange individuals emerged into the light of the lamps. They walked in squads, in rows of three, with an odd, embarrassed step, head dangling in front, arms rigid. On their heads they wore comic berets and were all dressed in long striped overcoats, which even by night and from a distance looked filthy and in rags. We looked at each other without a word. It was all incomprehensible and mad, but one thing we had understood. This was the metamorphosis that awaited us. Tomorrow we would be like them†(20-21). They are transformed into tired beasts, desperate and alone, aware of only hunger and cold; they show no signs of solidarity or camaraderie, for in the Lager everyone is on his own. They must shut themselves off from reality to survive; they must dispose of all morality and thought before it destroys them. Only in this way can they survive and even then they are guaranteed nothing. They begin to despise themselves, the sad, pathetic faces they see each day, each a reflection of the other, all reduced to ghosts by the machinations of the Lager. This moral hierarchy based on the depraved morals of madmen, sought to destroy the soul of the Jewish people, to torture them into oblivion. They created a monstrous world, where the weak are crushed and the only escape was through the Chimney. This tragedy beyond all comparison in human history told a story. A story that must be told over and over again, no one should be allowed to forget them. Their stories are all the same â€Å"all full of tragic disturbing necessity†¦ simple and incomprehensible like the stories in the Bible. But are they not themselves stories of a new Bible? †(65-66). This new Bible, this new Exodus would renew the life of the Jewish people, and like all the times before they would begin again. They survived â€Å"to tell the story, to bear witness†¦ to save at least the skeleton, the scaffolding, the form of civilization†(41) and with their help the world would be revived, its humanity restored, and that alien world destroyed and those responsible for it punished. The Lager would remain, a stark reminder of â€Å"what man’s presumption made of man in Auschwitz. †(55)

The Vietnamese American 1.5 generation Stories of war, Revolution, Flig

When we talk about the Vietnamese, most people will think them as refugees because of their history. The book â€Å"The Vietnamese American 1.5 generation Stories of war, Revolution, Flight, and New Beginnings† by Sucheng Chan described the history of Vietnam; the Vietnamese refugees’ experiences and sufferings they had gone through while on boat to go out of Vietnam, and their settlements outside of Vietnam. The Vietnamese as refugees who had gone through many hardships while escaping to other countries. Vietnam had to fight for its independence from Japan and French. It made them suffered more when they had to fight against their own people during the Civil War. By trying to declare its independence, Ho Chi Minh started the revolution in the North to fight with invaders, and fought with the South people who was supported by the United States to finally took over the South and make Vietnam a Communist state; this civil war caused many Vietnamese suffered because they h ad to fight with their own people in the war and became the refugees to leave Vietnam to seek for freedoms after the Fall of Saigon. The book is divided into two sections. The first section is about the history of Vietnam and the Vietnamese refugees’ experiences and different reasons they travel to America or other countries. In the early time of the history, Vietnam was influenced by China that the emperor was in control of ruling the dynasties. The French went to Vietnam in 1614 to try to colonize and cultivate the Vietnamese to promote Catholicism. French forced Vietnam to sign The Treaty of Saigon in 1862 to cede Saigon to French. Under French’s control and suppression, the Vietnamese wanted to start the movement of anti-French and declare its independence. To fig... ...ch discriminations in school because China’s power is increasing. Not like Vietnam in 1970s, it has been 30 years after I came here because a lot of things are different nowadays. As refugees in America, Vietnamese experienced many difficulties adopting the American culture. They came from Asia where there is complete different culture from the United States. They had to change their life styles and believe. In order to fit into the American culture, they have to start everything newly again and abundant everything they had in Vietnam. They were still being discriminated at even though they tried to assimilate fully. They did not have to experience this if there were no wars in Vietnam. The war only gave them suffering and nothing else. Especially, when there is a Civil War when people have to fight with their own people. Therefore, peace is important to people.

Agency Costs and Corporate Governance Mechanisms

Agency costs and corporate governance mechanisms: Evidence for UK firms Chrisostomos Florackis and Aydin Ozkan* University of York, UK Abstract In this paper, we aim to extend the empirical literature on the determinants of agency costs by using a large sample of UK listed firms. To do so, we employ two alternative proxies for agency costs: the ratio of total sales to total assets (asset turnover) and the ratio of selling, general and administrative expenses (SG&A) to total sales. In our analysis, we control for the influence of several internal governance mechanisms or devices that were ignored by previous studies.Also, we examine the potential interactions between these mechanisms and firm growth opportunities in determining agency costs. Our results reveal that the capital structure characteristics of firms, namely bank debt and debt maturity, constitute two of the most important corporate governance devices for UK companies. Also, managerial ownership, managerial compensation and ownership concentration seem to play an important role in mitigating agency costs. Finally, our results suggest that the impact exerted by internal governance mechanisms on agency costs varies with firms’ growth opportunities.JEL classification: G3; G32 Keywords: Agency costs; Growth opportunities; Internal Corporate Governance Mechanisms. * Corresponding author.

Introduction Following Jensen and Meckling (1976), agency relations within the firm and costs associated with them have been extensively investigated in the corporate finance literature.There is a great deal of empirical work providing evidence that financial decisions, investment decision s and, hence, firm value are significantly affected by the presence of agency conflicts and the extent of agency costs. The focus of these studies has been the impact of the expected agency costs on the performance of firms. 1 Moreover, the implicit assumption is that, in imperfect capital markets, agency costs arising from conflicts between firms’ claimholders exist and the value of firms decreases if the market expects that these costs are likely to be realised.It is also assumed that there are internal and external corporate governance mechanisms that can help reduce the expected costs and their negative impact on firm value. For example, much of prior work on the ownership and performance relationship relies on the view that managerial ownership can align the interests of managers and shareholders and hence one would observe a positive impact exerted by managerial shareholdings on the performance of firms. The positive impact is argued to be due to the decrease in the exp ected costs of the agency conflict between managers and shareholders.Despite much valuable insights provided by this strand of literature, however, only very few studies directly tackle the measurement issue of the principal variable of interest, namely agency costs. Notable exceptions are Ang et al. (2000) and Sign and Davidson (2003), which investigate the empirical determinants of agency costs and focus on the role of debt and ownership structure in mitigating agency problems for the US firms. In doing so, they use two alternative proxies for agency costs: the ratio of total sales to total assets (asset turnover) and the ratio of selling, general and administrative expenses (SG&A) to total sales.In line with the findings of prior research they provide evidence for the view that managerial ownership aligns the interests of managers and shareholders and, hence, reduces agency costs in general. However, there is no consensus on the role of debt in mitigating such problems and associ ated costs. Ang et al. (2000) point out that debt has an alleviating role whereas Sign and Davidson (2003) an aggravating one. The objective of this paper is to extend the investigation of these studies by analysing empirically the determinants of agency costs in the UK for a large sample of 1See, for example, Morck et al. (1988); McConnell and Servaes (1990); and Agrawal and Knoeber (1996) among others. 2 listed firms. Following the works of Ang et al. (2000) and, Sign and Davidson (2003), we model both proxies of agency costs: asset turnover and the (SG&A) ratio. More specifically, we empirically examine the impact of capital structure, ownership, board composition and managerial compensation on the costs likely to arise from agency conflicts between managers and shareholders. In doing so, we also pay particular attention to the role of growth opportunities in influencing the effectiveness of internal governance mechanisms in reducing agency costs. In carrying out the analysis in this paper, we aim to provide insights at least in three important areas of the empirical research on agency costs. First, in investigating the determinants of agency costs, the analysis of this paper incorporates important firmspecific characteristics (internal corporate governance devices) that possibly affect agency costs but were ignored by previous studies.For example, we explore the role the debt maturity structure of firms can play in controlling agency costs. It is widely acknowledged that short-term debt may be more effective than long-term debt in reducing the expected costs of the underinvestment problem of Myers (1977). 3 Accordingly, in our analysis, we consider the maturity structure of debt as a potential governance device that is effective in reducing the expected costs of the agency conflict between shareholders and debtholders. Similar to Ang et al. 2000) that investigate if bank debt creates a positive externality in the form of lower agency costs, we also check i f the source of debt financing matters in mitigating agency problems. Another potentially effective corporate governance mechanism we consider relates to managerial compensation. Recent studies suggest that compensation contracts can motivate managers to take actions that maximize shareholders’ wealth (see, e. g. , Core et al. , 2001; Murphy, 1999 among others). This is based on the view that financial â€Å"carrots† motivate managers to maximize firm value.That is, a manager will presumably be less likely, ceteris paribus, to exert insufficient effort and risk the loss of his job the greater the level of his compensation. Several empirical studies provide evidence for the effectiveness of managerial compensation as a corporate governance mechanism. For instance, 2 As explained later in the paper, the two proxies for agency costs that are used in our analysis are more likely to capture the agency problems between managers and shareholders. However, we do not rule out t he possibility that they may also capture the agency problems between shareholders and debtholders. It is argued that firm with greater growth opportunities should have more short-term debt because shortening debt maturity would make it more likely that debt will mature before any opportunity to exercise the growth options. Consistent with this prediction, there are several empirical debt maturity studies that find a negative relation between maturity and growth opportunities (see, e. g. , Barclay and Smith, 1995; Guedes and Opler, 1996; and Ozkan, 2000 among others). 3 Hutchinson and Gul (2004) find that managers’ compensation can moderate the negative association between growth opportunities and firm value.In this paper, we examine the effectiveness of managerial compensation as a corporate governance mechanism by including the salary of managers in our empirical model. We also acknowledge that there have been concerns about excessive compensation packages and their negativ e impact on corporate performance. Accordingly, we investigate the possibility of a non-monotonic impact the managerial compensation may exert on agency costs. Second, our empirical model captures potential interactions between corporate governance mechanisms and growth opportunities.Following McConnell and Servaes (1995) and Lasfer (2002), we expect the effectiveness of governance mechanisms in reducing agency problems to be dependent on firm’s growth opportunities. In particular, if agency problems are associated with greater information asymmetry (a common problem in high-growth firms), we expect the effectiveness of corporate governance mechanisms in mitigating asymmetric information problems to increase in high-growth firms (Smith and Watts, 1992 and Gaver and Gaver, 1993).However, if, as argued by Jensen (1986), agency problems are associated with conflicts over the use of free cash flow (a common problem in low-growth firms), we expect governance mechanisms that are li kely to mitigate such problems to play a more important role in low-growth firms (Jensen, 1986). Last but not least, in contrast to previous studies that focus on the US market, we provide evidence for UK firms. Although the UK and the US are usually characterized as having a similar â€Å"common law† regulatory system (see, e. g. , La Porta et al. 1998), the UK market bears significant distinguishing characteristics. 4 It is argued that several of these characteristics may contribute to a more significant degree of managerial discretion and, hence, higher level of managerial agency costs. For example, despite the relatively high proportion of shares held by financial institutions, there is a great deal of evidence that financial investors do not take an active role in corporate governance. Similarly, UK boards are usually characterized as corporate devices that provide weak disciplinary function.More specifically, weak fiduciary obligations on directors have resulted in none xecutives playing more an advisory than a monitoring role. 5 Consequently, the investigation of agency issues and the effectiveness of the alternative governance 4 For a more detailed discussion about the characteristics of the prevailing UK corporate governance system see Short and Keasey (1999); Faccio and Lasfer (2000); Franks et al. (2001); and Ozkan and Ozkan (2004). 5 Empirical studies by Faccio and Lasfer (2000), Goergen and Rennebog (2001), Franks et al. 2001) and Short and Keasey (1999) provide evidence on the weak role of institutions and board of directors in reducing agency problems in the UK. 4 mechanisms in the UK, in a period that witnesses an intensive discussion of corporate governance issues, would be of significant importance. Our results strongly suggest that managerial ownership constitutes a strong corporate governance mechanism for the UK firms. This result is consistent with the findings provided by Ang et al. (2000) and Sign and Davidson (2003) for the US fi rms.Ownership concentration and salary also seem to play a significant role in mitigating agency related problems. The results concerning the role of capital structure variables on agency costs are striking. It seems that both the source and the maturity structure of corporate debt have a significant effect on agency costs. Finally, there is strong evidence that specific governance mechanisms are not homogeneous but vary with growth opportunities. For instance, we find that executive ownership is more effective as a governance mechanism for high-growth firms.This result is complementary to the results obtained by Smith and Watts (1992), Gaver and Gaver (1993) and Lasfer (2002), which support the view that high-growth firms are likely to prefer incentive mechanisms (e. g. managerial ownership) whereas low-growth firms focus more on monitoring mechanisms (e. g. short-term debt). The remainder of the paper is organized as follows. In section 2 we discuss the related theory and formulat e our empirical hypotheses. Section 3 describes the way in which we have constructed our sample and presents several descriptive statistics of that.Section 4 presents the results of our univariate, multivariate and sensitivity analysis. Finally, section 5 concludes. 2. Agency costs and Governance Mechanisms In what follows, we will discuss the potential interactions between agency costs and internal corporate governance mechanisms available to firms. Also, we will analyze how firm growth opportunities affect agency costs and the relationship between governance mechanism and agency costs. 2. 1 Debt Financing Agency problems within a firm are usually related to free cash-flow and asymmetric information problems (see, for example, Jensen, 1986 and Myers and Majluf, 1984).It is widely acknowledged that debt servicing obligations help reduce of agency problems of this sort. This is particularly true for the case of privately held debt. For example, bank 5 debt incorporates significant si gnalling characteristics that can mitigate informational asymmetry conflicts between managers and outside investors (Jensen, 1986; Stulz, 1990; and Ross, 1977). In particular, the announcement of a bank credit agreement conveys positive news to the stock market about creditor’s worthiness.Bank debt also bears important renegotiation characteristics. As Berlin and Mester (1992) argue, because banks are well informed and typically small in number, renegotiation of a loan is easier. A bank’s willingness to renegotiate and renew a loan indicates the existence of a good relationship between the borrower and the creditor and that is a further good signal about the quality of the firm. Moreover, it is argued that bank debt has an advantage in comparison to publicly traded debt in monitoring firm’s activities and in collecting and processing information.For example, Fama (1985) argues that bank lenders have a comparative advantage in minimizing information costs and get ting access to information not otherwise publicly available. Therefore, banks can be viewed as performing a screening role employing private information that allows them to evaluate and monitor borrowers more effectively than other lenders. In addition to debt source, the maturity structure of debt may matter. For example, short-term debt may be more useful than long-term debt in reducing free cash flow problems and in signalling high quality to outsiders.For example, as Myers (1977) suggests, agency conflicts between managers and shareholders such as the underinvestment problem can be curtailed with short-term debt. Flannery (1986) argues that firms with large potential information asymmetries are likely to issue short-term debt because of the larger information costs associated with long-term debt. Also, short-term debt can be advantageous especially for high-quality companies due to its low refinancing risk (Diamond, 1991). Finally, if yield curve is downward sloping, issuing sho rt-term debt increases firm value (Brick and Ravid, 1985).Consequently, bank debt and short-term debt are expected to constitute two important corporate governance devices. We include the ratio of bank debt to total debt and the ratio of short-term debt to total debt to our empirical model so as to approximate the lender’s ability to mitigate agency problems. Also, we include the ratio of total debt to total assets (leverage) to approximate lender’s incentive to monitor. In general, as leverage increases, so does the risk of default by the firm, hence the incentive for the lender to monitor the firm6. 6 Ang et al. 2000) focus on sample of small firms, which have do not have easy access to public debt, and examine the impact of bank debt on agency costs. On the contrary, Sign and Davidson (2003) focus on a sample of large firms, which have easy access to public debt, and examine the impact of public debt on 6 2. 2 Managerial Ownership The conflicts of interest between m anagers and shareholders arise mainly from the separation between ownership and control. Corporate governance deals with finding ways to reduce the magnitude of these conflicts and their adverse effects on firm value.For instance, Jensen and Meckling (1976) suggest that managerial ownership can align the interest between these two different groups of claimholders and, therefore, reduce the total agency costs within the firm. According to their model, the relationship between managerial ownership and agency costs is linear and the optimal point for the firm is achieved when the managers acquires all of the shares of the firm. However, the relationship between managerial ownership and agency costs can be non-monotonic (see, for example, Morck et al. , 1988; McConnel and Servaes, 1990,1995 and, Short and Keasey, 1999).It has been shown that, at low levels of managerial ownership, managerial ownership aligns managers’ and outside shareholders’ interests by reducing manager ial incentives for perk consumption, utilization of insufficient effort and engagement in nonmaximizing projects (alignment effect). After some level of managerial ownership, though, managers exert insufficient effort (e. g focus on external activities), collect private benefits (e. g. build empires or enjoy perks) and entrench themselves (e. g. undertake high risk projects or bend over backwards to resist a takeover) at the expense of other investors (entrenchment effect).Therefore the relationship between the two is non-linear. The ultimate effect of managerial ownership on agency costs depends upon the trade-off between the alignment and entrenchment effects. In the context of our analysis we propose a non-linear relationship between managerial ownership and managerial agency costs. However, theory does not shed much light on the exact nature of the relationship between the two and, hence, we do not know which of the effects will dominate the other and at what levels of manageria l ownership.We, therefore, carry out a preliminary investigation about the pattern of the relationship between managerial ownership and agency costs. Figure 1 presents the way in which the two variables are associated. [Insert Figure 1 here] agency costs. Our study is more similar to that of Ang et al (2000) given that UK firms use significant amounts of bank debt financing (see Corbett and Jenkinson, 1997). 7 Clearly, at low levels of managerial ownership, asset turnover and managerial ownership are positively related. However, after managerial ownership exceeds the 10 per cent level, the relationship turns from positive to negative.A third turning point is that of 30 percent after which the relationship seems to turn to positive again. Consequently, there is evidence both for the alignment and the entrenchment effects in the case of our sample. In order to capture both of them in our empirical specification, we include the level, the square and the square of managerial ownership i n our model as predictors of agency costs. 2. 3 Ownership Concentration A third alternative for alleviating agency problems is through concentrated ownership.Theoretically, shareholders could take themselves an active role in monitoring management. However, given that the monitoring benefits for shareholders are proportionate to their equity stakes (see, for example, Grossman and Hart, 1988), a small or average shareholder has little or no incentives to exert monitoring behaviour. In contrast, shareholders with substantial stakes have more incentives to supervise management and can do so more effectively (see Shleifer and Vishny, 1986; Shleifer and Vishny, 1997 and Friend and Lang, 1988).In general, the higher the amount of shares that investors hold, the stronger their incentives to monitor and, hence, protect their investment. Although large shareholders may help in the reduction of agency problems associated with managers, they may also harm the firm by causing conflicts between large and minority shareholders. The problem usually arises when large shareholders gain nearly full control of a corporation and engage themselves in self-dealing expropriation procedures at the expense of minority shareholders (Shleifer and Vishny, 1997).Also, as Gomez (2000) points out, these expropriation incentives are stronger when corporate governance of public companies insulates large shareholders from takeover threats or monitoring and the legal system does not protect minority shareholders because either of poor laws or poor enforcement of laws. Furthermore, the existence of concentrated holdings may decrease diversification, market liquidation and stock’s ability to grow and, therefore, increase the incentives of large shareholders to expropriate firm’s resources.Several empirical studies provide evidence consistent with that view (see, for example, Beiner et al, 2003). In order to test the impact of ownership concentration on agency costs, we include a var iable that refers to the sum of stakes of shareholders with equity stake greater than 3 8 per cent in our regression equation. The results remain robust when the threshold value changes from 3 per cent to 5 per cent or 10 per cent. 2. 4 Board of Directors Corporate governance research recognizes the essential role performed by the board of directors in monitoring management (Fama and Jensen, 1983; Weisbach, 1988 and Jensen, 1993).The effectiveness of a board as a corporate governance mechanism depends on its size and composition. Large boards are usually more powerful than small boards and, hence, considered necessary for organizational effectiveness. For instance, as Pearce and Zahra (1991) point out, large powerful boards help in strengthening the link between corporations and their environments, provide counsel and advice regarding strategic options for the firm and play crucial role in creating corporate identity. Other studies, though, suggest that large boards are less effecti ve than large boards.The underlying notion is that large boards make coordination, communication and decision-making more cumbersome than it is in smaller groups. Recent studies by Yermack, 1996; Eisenberg et al. , 1998 and Beiner et al, 2004 support such a view empirically. The composition of a board is also important. There are two components that characterize the independence of a board, the proportion of non-executive directors and the separated or not roles of chief executive officer (CEO) and chairman of the board (COB).Boards with a significant proportion of non-executive directors can limit the exercise of managerial discretion by exploiting their monitoring ability and protecting their reputations as effective and independent decision makers. Consistent with that view, Byrd and Hickman (1992) and Rosenstein and Wyatt (1990) propose a positive relationship between the percentage of non-executive directors on the board and corporate performance. Lin et al. (2003) also propose a positive share price reaction to the appointment of outside directors, especially when board ownership is low and the appointee possesses strong ex ante monitoring incentives.Along a slightly different dimension, Dahya et al. (2002) find that top-manager turnover increases as the fraction of outside directors increases. Other studies find exactly the opposite results. They argue that non-executive directors are usually characterized by lack of information about the firm, do not bring the requisite skills to the job and, hence, prefer to play a less confrontational role rather than a more critical monitoring one (see, for example, Agrawal and Knoeker, 1996; Hermalin 9 nd Weisbach, 1991, and Franks et al. , 2001)7. As far as the separation between the role of CEO and COB is concerned, it is believed that separated roles can lead to better board performance and, hence, less agency conflicts. The Cadbury (1992) report on corporate governance stretches that issue and recommends that C EO and COB should be two distinct jobs. Firms should comply with the recommendation of the report for their own benefit. A decision not to combine these roles should be publicly explained.Empirical studies by Vafeas and Theodorou (1998), and Weir et al. (2002), though, which study that issue for the case of the UK market, provide results that do not support Cadbury’s stance that the CEO – COB duality is undesirable. In the context of the UK market, UK boards are believed to be less effective than the US ones. For instance,. To test the effectiveness of the board of directors in mitigating agency problems we include three variables in our empirical model: a) the ratio of the number of non-executive directors to he number of total directors, b) the total number of directors (board size) and c) a dummy variable which takes the value of 1 when the roles of CEO and COB are not separated and 0 otherwise. 2. 5 Managerial Compensation Another important component of corporate g overnance is the compensation package that is provided to firm management. Recent studies by Core et al. (2001) and Murphy (1999) suggest, among others, that compensation contracts, whose use has been increased dramatically during the 90’s, can motivate managers to take actions that maximize shareholders’ wealth.In particular, as Core et al. (2001) point out, if shareholders could directly observe the firm’s growth opportunities and executives’ actions no incentives would be necessary. However, due to asymmetric information between managers and shareholders, both equity and compensation related incentives are required. For example, an increase in managerial compensation may reduce managerial agency costs in the sense that satisfied managers will be less likely, ceteris paribus, to utilize insufficient effort, perform expropriation behaviour and, hence, risk the loss of their job.Despite the central importance of the issue, only a few empirical studies exa mine the impact of managerial compensation components on corporate performance. For example, Jensen and Murthy 7 Such a result may be consistent with the governance system prevailing in the UK market given the fact that UK legislation encourages non-executive directors to be inactive since it does not impose fiduciary obligations on them. Also, UK boards are dominated by executive directors, which have less monitoring power.Franks et al. (2001) confirm this view by providing evidence on a non-disciplinary role of nonexecutive directors in the UK. 10 (1990) find a statistically significant relationship between the level of pay and performance. Murphy (1995), finds that the form, rather than the level, of compensation is what motivates managers to increase firm value. In particulars, he argues that firm performance is positively related to the percentage of executive compensation that is equity based.More recently, Hutchinson and Gul (2004) analyze whether or not managers’ comp ensation can moderate the negative association between growth opportunities and firm value8. The results of this study indicate that corporate governance mechanisms such as managerial remuneration, managerial ownership and non-executive directors possibly affect the linkages between organizational environmental factors (e. g. growth opportunities) and firm performance.Finally, Chen (2003) analyzes the relationship between equity value and employees’ bonus. He finds that the annual stock bonus is strongly associated with the firm’s contemporaneous but not future performance. Managerial compensation, though, is considered to be a debated component of corporate governance. Despite its potentially positive impact on firm value, compensation may also work as an â€Å"infectious greed† which creates an environment ripe for abuse, especially at significantly high levels.For instance, remuneration packages usually include extreme benefits for managers such as the use of private jet, golf club membership, entertainment and other expenses, apartment purchase etc. Benefits of this sort usually cause severe agency conflicts between managers and shareholders. 9 Therefore, it is possible that the relationship between compensation and agency costs is non-monotonic. Similar to the case of managerial ownership, we carry out a preliminary investigation about the pattern of the relationship between salary and agency costs.As shown in figure 2, the relationship between salary and agency costs is likely to be non-linear10. In our empirical model, we include the ratio of the total salary paid to executive directors to total assets as a determinant of agency costs. Also, in order to capture potential 8 Rather, the majority of the studies in that strand of literature reverse the causation and examine the impact of performance changes on executive or CEO compensation (see, for example, Rayton, 2003 among others). Concerns about excessive compensation packages and their negative impact on corporate performance have lead to the establishment of basic recommendations in the form of â€Å"best practises† in which firms should comply so as the problem with excessive compensation to be diminished. In the case of the UK market, for example, one of the basic recommendations of the Cadbury (1992) report was the establishment of an independent compensation committee. Also, in a posterior report, the Greenbury (1995) report, specific propositions about remuneration issues were made.For example, an issue that was stretched was the rate of increase in managerial compensation. In the case of the US market, the set of â€Å"best practises† includes, among others, the establishment of a compensation committee so as transparency and disclosure to be guaranteed (same practise an in the UK) and the substitution of stock options as compensation components with other tools that promote the long-term value of the company 10 A similar preliminary ana lysis is carried out so as to check potential non-linearities concerning the relationship between the rest of internal governance mechanisms and agency costs.Our results (not reported) indicate that none of them is related to agency costs in a non-linear way. 11 non-linearities, we include higher ordered salary terms in the regression equation. Finally, we include a dummy variable, which takes the value of 1 when a firm pays options or bonuses to managers and 0 otherwise. Including that dummy variable in our analysis enables us to test whether or not options and bonuses themselves provide incentives to managers.As Zhou (2001) points out, ignoring options is likely to incur serious problems unless managerial options are either negligible compared to ownership or almost perfectly correlated with ownership. [Insert Figure 2 here] 2. 6 Growth Opportunities The magnitude of agency costs related to underinvestment, asset substitution and free cash flow differ significantly across high-gro wth and low-growth firms. In the underinvestment problem, managers may decide to pass up positive net present value projects since the benefits would mainly accrue to debt-holders.This is more severe for firms with more growth-options (Myers, 1977). Asset substitution problems, which occur when managers opportunistically substitute higher variance assets for low variance assets, are also more prevalent in high-growth firms due to information asymmetry between investors and borrowers (Jensen and Meckling, 1976). High-growth firms, though, face lower free cashlow problems, which occur when firms have substantial cash reserves and a tendency to undertake risky and usually negative NPV investment projects (Jensen, 1986).Given the different magnitude and types of agency costs between high-growth and low-growth firms, we expect the effectiveness of corporate governance mechanisms to vary with growth opportunities. In particular, if agency problems are associated with greater underinvestme nt or information asymmetry (a common problem in high-growth firms), we expect corporate governance mechanisms that mitigate these kinds of problems to be more effective in high-growth firms (Smith and Watts, 1992 and Gaver and Gaver, 1993).However, if, as argued by Jensen (1986), agency problems are associated with conflicts over the use of free cash flow (a common problem in low-growth firms), we expect governance mechanisms that mitigate such problems to play a more important role in low-growth firms (Jensen, 1986). Several empirical studies that model company performance confirm the existence of potential interactions between internal governance mechanism and growth opportunities. For example, McConnell and Servaes (1995) find that the relationship between firm value and leverage is negative for high-growth firms and positive for low12 growth firms.Their results also indicate that equity ownership matters, and the way in which it matters depends upon investment opportunities. Sp ecifically, they provide weak evidence that on the view that the allocation of equity ownership between corporate insiders and other types of investors is more important in low-growth firms. Also, Lasfer (2002) points out that high-growth firm (low-growth firms) rely more on managerial ownership (board structure) to mitigate agency problems. Finally, Chen (2003) finds that the positive relationship between annual stock bonus and equity value is stronger for firms with greater growth opportunities.In order to capture potential interaction effects, we include interaction terms between proxies for growth opportunities and governance mechanisms in our empirical model and, also, employ sample-splitting methods (see, for example, McConnell and Servaes, 1995 and Lasfer, 2002). Based on previous empirical evidence the prediction we make is that mechanisms that are used to mitigate asymmetric information problems (free cash flow problems) are stronger in high-growth firms (low-growth firms). 3. Data and Methodology 3. 1 Data For our empirical analysis of agency costs we use a large sample of ublicly traded UK firms over the period 1999-2003. We use two data sources for the compilation of our sample. Accounting data and data on the market value of equity are collected from Datastream database. Specifically, we use Datastream to collect information for firm size, market value of equity, annual sales, selling general and administrative expenses, level of bank debt, short-term debt and total debt. Information on firm’s ownership, board and managerial compensation structure is derived from the Hemscott Guru Academic Database.This database provides financial data for the UK’s top 300,000 companies, detailed data on all directors of UK listed companies, live regulatory and AFX News feeds and share price charts and trades. Specifically, we get detailed information on the level of managerial ownership, ownership concentration, size and composition of the board, ma nagerial salary, bonus, options and other benefits. Despite the fact that data on directors are provided in a spreadsheet format, information for each item is given in a separate file. This makes data collection for the required variables fairly complicated.For example, in order to get information about the amount of shares held by executive directors we have to combine two different files: a) the 13 file that contains data on the amount of shares held by each director and b) the file that provides information about the type of each directorship (e. g. executive director vs. nonexecutive director). Also, we have to take into account the fact that several directors in the UK hold positions in more than one company. Complications also arise when we attempt to collect information about the composition of the board and the remuneration package that is provided to executive directors.The way in which our final sample is compiled is the following: we start with a total of 1672 UK listed f irms derived from Datastream. This number reduces to 1450 firms after excluding financial firms from the sample. After matching Datastream data with the data provided by Hemscott, the number of firms further decreases to 1150. Missing firmyear observations for any variable in the model during the sample period are also dropped. Finally, we exclude outliers so as to avoid the problem with extreme values. We end up with 897 firms for our empirical analysis. 3. Dependent Variable In our analysis we use two alternative proxies to measure agency costs. Firstly, we use the ratio of annual sales to total assets (Asset Turnover) as an inverse proxy for agency costs. This ratio can be interpreted as an asset utilization ratio that shows how effectively management deploys the firm’s assets. For instance, a low asset turnover ratio may indicate poor investment decisions, insufficient effort, consumption of perquisites and purchase of unproductive products (e. g. office space). Firms wit h low asset turnover ratios are expected to experience high agency costs between managers and shareholders11.A similar proxy for agency costs is also used in the studies of Ang et al. (2000) and Sign and Davidson (2003). However, Ang et al. (2000), instead of using the ratio directly, they use the difference in the ratios of the firm with a certain ownership and management structure and the no-agency-cost base case firm. Secondly, following Sign and Davidson (2003), we use the ratio of selling, general and administrative (SG&A) expenses to sales (expense ratio). In contrast to asset turnover, expense ratio is a direct proxy of agency costs.SG&A expenses include salaries, commissions charged by agents to facilitate transactions, travel expenses for executives, advertising and marketing costs, rents and other utilities. Therefore, expense ratio should 11 The asset turnover ratio may also capture (to some extent) agency costs of debt. For instance, the sales ratio provides a good signa l for the lender about how effectively the borrower (firm) employs its assets and, therefore, affects the cost of capital 14 reflect to a significant extent managerial discretion in spending company resources.For example, as Sign and Davidson (2003) point out, â€Å"management may use advertising and selling expenses to camouflage expenditures on perquisites† p. 7. Firms with high expense ratios are expected to experience high agency costs between managers and shareholders12. 3. 3 Independent Variables Our empirical model includes a set of corporate governance variables related to firm’s ownership, board, compensation and capital structure. Several control variables are also incorporated. For example, we use the logarithm of total assets in 1999 prices as a proxy for firm size (SIZE).Also, we include the market-to-book value (MKTBOOK) as a proxy for growth opportunities. Finally, we divide firms into 15 sectors and include 14 dummy variables accordingly so as to contro l for sector specific effects. Analytical definitions for all these variables are given in Table 1. [Insert Table 1 here] 3. 4 Methodology We examine the determinants of agency costs by employing a cross sectional regression approach. Following Rajan and Zingales (1995) and Ozkan and Ozkan (2004), the dependent variable is measured at some time t, while for the independent variables we use average-past values.Using averages in the way we construct our explanatory variables helps in mitigating potential problems that may arise due to short-term fluctuations and extreme values in our data. Also, using past values reduces the likelihood of observed relations reflecting the effects of asset turnover on firm specific factors. Specifically, the dependent variable is measured in year 2003. For accounting variables and the market-tobook ratio we use average values for the period 1999-2002. Ownership, board and compensation structure variables are measured in year 2002.Given that equity owne rship characteristics in a country are relatively stable over a certain period of time, we do not expect that measuring them in a single year would yield a significant bias in our results (see also La Porta et al. , 2002, among others). 12 An alternative proxy for agency costs between managers and shareholders, which is not used in our paper though, is the interaction of company’s growth opportunities with its free cash flow (see Doukas et al. , 2002). 15 Our approach captures potential interaction effects that may be present.For example, as explained analytically in section 2. 6, the nature of the relationship between the alternative governance mechanisms or devices and agency costs may vary with firm’s growth opportunities. To explore that possibility, we firstly interact our proxy for growth opportunities (MKTBOOK) with the alternative corporate governance mechanisms. In this way, we test for the existence of both main effects (the impact governance variables on age ncy costs) and conditional effects (the impact of growth opportunities on the relationship between governance variables and agency costs).Additionally, we split the sample into high-growth and low-growth firms and estimate our empirical models for each sample separately. Then we check whether the coefficients of governance variables retain their sign and their significance across the two sub-samples. 3. 5 Sample Characteristics Table 2 presents descriptive statistics for the main variables used in our analysis. It reveals that the average values of asset turnover ratio and SG&A ratio are 1. 24 and 0. 45 respectively. The mean value for managerial ownership is 14. 4 per cent of which the average proportion of stakes held by executive (non-executive) directors is 10. 68 per cent (4. 06 per cent). The ownership concentration reaches the level of 37. 19 per cent, on average, in the UK firms. Also, the average proportion of non-executive directors is 49. 5 per cent and the average board size consists of 6. 97 directors. Finally, we were able to identify only 73 firms out of the final 897 (8. 1 per cent) in which the same person held the positions of CEO and COB. As far as the capital structure variables are concerned, the average proportion of bank debt on firm’s capital structure is 55. 5 per cent and that of short-term debt is 49. 53 per cent. Finally, the average market-to-book value is 2. 09. In general, these values are in line with those reported in other studies for UK firms (see, for example, Ozkan and Ozkan, 2004 and Short and Keasey, 1999). [Insert Table 2 here] The results of the Pearson’s Correlation of our variables are reported in Table 3. Our inverse proxy for agency costs, asset turnover, is clearly positively correlated to managerial ownership, executive ownership, salary, bank debt and short-term debt.Ownership concentration is also positively related to asset turnover but the correlation coefficient is not statistically significant. On the contrary, board size and non-executive 16 directors are found to be negatively correlated with asset turnover. Finally, as expected, asset turnover is found to be negatively correlated with both growth opportunities and firm size. The results for our second proxy for agency costs, SG&A, are qualitatively similar with a few exceptions (e. g. short-term debt) but with opposite signs given that SG&A is a direct and not an inverse proxy for agency costs.

Empirical Results 4. 1 Univariate analysis In Table 4 we report univariate mean-comparison test results of the sample firm subgroups categorized on the basis of above and below median values for managerial ownership, ownership concentration, board size, proportion of non-executives, bank debt, short-term debt, total debt, salary, firm size and growth opportunities. Firms with above median managerial ownership (ownership concentration) have asset turnover of 1. 34 (1. 31) whereas those with below median ma nagerial ownership (ownership concentration) have asset turnover of 1. 5 (1. 17). These differences are statistically significant at the 1 per cent (5 per cent) level. The results for executive ownership, salary, bank debt and short-term debt are also found to be statistically significant and are in the hypothesized direction. Specifically, we find that firms with above median values for all the above mentioned variables have relatively higher asset utilization ratios. On the contrary, there is evidence that firms with larger board sizes indicate significantly lower asset utilization ratios. Insert Table 4 here] In panel B of the same table we report the results using SG&A expense ratio as a proxy for agency costs. Results are in general not in line with the hypothesized signs with notable exceptions those of ownership concentration and growth opportunities. For example, firms with above median ownership concentration (MKTBOOK) have an SG&A expense ratio of 0. 41 (0. 55) whereas fir ms with below median ownership concentration (MKTBOOK) have an SG&A expense ratio of 0. 49 (0. 36).However, the results for managerial ownership, salary and short-term debt suggest that these governance mechanisms or devices are not effective in protecting firms from excessive SG&A 17 expenses. Sign and Davidson (2003) obtains a set of similar results, for the case when agency costs are approximated with the SG&A ratio. Overall, the univariate analysis indicates several corporate governance mechanisms or devices, such as managerial ownership, ownership concentration, salary, bank debt and short-term debt, which can help mitigate agency problems between managers and shareholders.Also, consistent with previous studies, we find that the relation between governance variables and agency costs is stronger for the asset turnover ratio than the SG&A expense ratio. The analysis that follows allows us to test the validity of these results in a multivariate framework. 4. 2 Multivariate analysi s In this section we present our results that are based on a cross sectional regression approach. We start with a linear specification model, where we include only total debt from our set of capital structure variables (model 1).In general, the estimated coefficients are in line with the hypothesized signs. Specifically, consistent with the results of Ang et al. (2000) and Sign and Davidson (2003), we find both managerial ownership and ownership concentration to be positively related to asset-turnover. The coefficients are statistically significant at the 5 per cent and 1 per cent significance level respectively. On the contrary, the coefficient for board size is negative, which probably indicates that firms with larger board size are less efficient in their asset utilization.Also, the results for our proxy for growth opportunities (MKTBOOK) support the view that high-growth firms suffer from higher agency costs than low-growth firms. Finally, there is strong evidence that manageria l salary can work as an effective incentive mechanism that helps aligning the interests of managers with those of shareholders. Specifically, the coefficient for salary is positive and statistically significant to the 1 per cent level. Therefore, compared to previous studies, our empirical model provides evidence on the existence of an additional potential corporate governance mechanism available to firms. Insert Table 5 here] In model 2 we incorporate two additional capital structure variables, the ratio of bank debt to total debt and the ratio of short-term debt to total debt, in order to test whether debtsource and debt-maturity impacts agency costs. Also, we split managerial ownership into executive ownership (the amount of shares held by executive directors) and non-executive 18 ownership (the amount of shares held by non-executive directors). We do this because we expect that equity ownership works as a better incentive mechanism in the hands of executive directors rather in t he hands of non-executive directors.According to our results, bank debt is positively related to asset turnover. Also, in addition to debt source, the maturity structure of debt seems to have a significant effect on agency costs. The coefficient of short-term debt is positive and statistically significant at the 1 per cent significance level. Furthermore, there is evidence that from total managerial ownership, only the amount of shares held by executive directors can enhance asset utilization and, hence, align the interest of managers with those of shareholders.In model 3 we estimate a non-linear model by adding the square of salary. As explained earlier in the paper, a priori expectations, which are supported by preliminary graphical investigation, suggest that the relationship between asset turnover and salary can be non-monotonic. Our results provide strong evidence that the relationship between salary and asset turnover is non-linear. In particular, at low levels of salary, the relationship between salary and asset turnover is positive. However, at higher levels of salary, the relationship becomes negative.This result is consistent with studies that suggest that extremely high levels of salary usually work as an â€Å"infectious greed† and create agency conflicts between managers and shareholders. The coefficients of the remaining variables are similar to those reported in models 1 and 2. Finally, in model 4 we allow for a non-linear relationship between executive ownership and agency costs. However, our results do not support such a relationship and, therefore, the square term in our following models13.To sum up, the results of Table 5 indicate that managerial ownership (executive ownership), ownership concentration, salary (when it is at low levels), bank debt and short-term debt can help in mitigating agency problems by enhancing asset utilization. Also, the coefficients for the control variables market to book and firm size, negative and positiv e respectively, suggest that smaller and non- growth firms are associated with reduced asset utilization ratio and, hence, more severe agency problems between managers and shareholders.As discussed earlier in the paper, there is a possibility that the nature of the relationship between the alternative governance mechanisms or devices and agency costs varies with firm’s growth opportunities. In Panel A of Table 6, we explore such a In trial regressions, which are not reported, the cubic term of executive ownership is also included in our model. Once more, the results do not support the existence of a non-monotonic relationship. 13 19 possibility by interacting those governance mechanisms found significant in models 1-4 with growth opportunities, proxied by market-to-book ratio.Our empirical results support the existence of two interaction effects. We find that executive ownership is an effective governance mechanism especially for high-growth firms (the coefficient EXECOWNER* MKTBOOK is positive and statistically significant). This result is consistent with the study of Lasfer (2002), which suggests that the positive relationship between managerial ownership and firm value is stronger in high-growth firms. On the contrary, the coefficient SHORT_DEBT*MKTBOOK is found to be negative and statistically significant.This means that the efficiency of short-term debt in mitigating agency problems is lower for high-growth firms. A possible explanation may be that short-term debt basically mitigates agency problems related to free cash flow. Given that high-growth firms do not suffer from severe free cash-flow problems (but mainly from asymmetric information problems), the efficiency of short-term debt as governance device decreases for these firms. One could argue, though, that short-term debt should be more important for the case of highgrowth firms since it helps reduce underinvestment problems.However, it seems that this effect is not very strong for the case in our sample. A similar result is obtained in McConnell and Servaes (1995) who find that the relationship between corporate value and leverage is positive (negative) for low-growth (high-growth) firms14. [Insert Table 6 here] Secondly, we use the variable MKTBOOK so as two split the sample into two subsamples. We label the upper 45 per cent in terms of MKTBOOK as â€Å"high-growth firms† and the lower 45 per cent as â€Å"low-growth firms†. Then, we re-estimate our basic model for the two sub-samples separately (Table 6, panel B).The results of this exercise confirm the existence of an interaction effect between executive ownership and asset turnover. In particular, the coefficient of EXECOWNER is positive and statistically significant only in the case of the sample that includes only high-growth firms. As far as short-term debt is concerned, it is found to be positive and statistically significant in both samples. 14 The idea in McConnell and Servaes (1995) is that d ebt has both a positive and a negative impact on the value of the firm because of its influence on corporate investment decisions.What possibly happens is that the negative effect of debt dominates the positive effect in firms with more positive net present value projects (i. e. , high-growth firms) and that the positive effect will dominate the negative effect for firms with fewer positive net present value projects (i. e. , low-growth firms). 20 To summarize, the results of our multivariate analysis suggest, among others, that executive ownership and ownership concentration can work as effective governance mechanisms for the case of the UK market.These results are in line with the ones reported by the studies Ang et al. (2000) and sign and Davidson (2003). Also, we find that, in addition to the source of debt, the maturity structure of debt can help to reduce agency conflicts between managers and shareholders. The fact that previous studies have ignored the maturity structure of d ebt may partly explain their contradicting results concerning the relationship between capital structure and agency costs. Furthermore, we find that salary can work as an additional mechanism that provides incentives to managers to take valuemaximizing actions.However, its impact on asset turnover is not always positive i. e. the relationship between asset turnover and salary is non-monotonic. Finally, there is strong evidence that the relationship between several governance mechanisms and agency costs varies with growth opportunities. Specifically, our results support the view that the positive relationship between executive ownership (short-term debt) is stronger for the case of high growth (low growth) firms. 4. Robustness checks Given the significant impact of growth opportunities on agency costs (main impact) and on the impact of other corporate governance mechanisms (conditional impact), we further investigate the relationship between growth opportunities, governance mechanism s and agency costs. At first, we substitute the variable MKTBOOK with an alternative proxy for growth opportunities. The new proxy is derived after employing common factor analysis, a statistical technique that uses the correlations between observed variables to estimate common factors and the structural relationships linking factors to observed variables.The variables which are used in order to isolate latent factors that account for the patterns of colinearity are following variables: MKTBOOK = Book value of total assets minus the book value of equity plus the market value of equity to book value of assets; MTBE = Market value of equity to book value of equity; METBA = Market value of equity to the book value of assets; METD = Market value of equity plus the book value of debt to the book value of assets. 21 These variables have been extensively used in the literature as alternative proxies for growth opportunities and Tobin’s Q.As shown in Table 7 (panel A) all these varia bles are highly correlated to each other. In order to make sure that principal component analysis can provide valid results for the case of our sample, we perform two tests in our sample, the Barlett’s test and the Kaiser-Meyer-Olkin test. The first test examines whether or not the intercorrelation matrix comes from a population in which the variables are noncollinear (i. e. an identity matrix). The second test is a test for sampling adequacy.The results from these tests, which are reported in panel B, are encouraging and suggest that common factor analysis can be employed in our sample since all the four proxies are likely to measure the same â€Å"thing† i. e. growth opportunities. Panel C presents the eigenvalues of the reduced correlation matrix of our four proxies for growth opportunities. Each factor whose eigenvalue is greater than 1 explains more variance than a single variable. Given that only one eigenvalue is greater than 1, our common factor analysis provid es us with one factor that can explain firm growth opportunities.Clearly, as shown in panel D, the factor is highly correlated with all MKTBOOK, MTBE, METBA and METD. We name the new variable GROWTH and use it as an alternative proxy for growth opportunities. Descriptive statistics for the variable GROWTH are presented in panel D. [Insert Table 7 here] Table 8 presents the results of cross-section analysis after using the variable GROWTH as proxy for agency costs. In general, the results of such a task are similar to the ones reported previously.For instance, there is strong evidence that executive ownership, ownership concentration, salary, short-term debt and, to some extent, bank debt are positively related to asset turnover. Also, there is some evidence supporting a non-linear relationship between salary and asset turnover. Finally, our results clearly indicate that agency costs differ significantly across high-growth and low-growth firms and, most importantly, there is a signif icant interaction effect between growth opportunities and executive ownership.However, we can not provide any evidence on the existence of an interaction between asset turnover and short-term debt. [Insert Table 8 here] 22 In panel B of table 8, we split our sample into high-growth and low-growth firms on the basis of high and low values for the variable GROWTH. Specifically, we label the upper 45 per cent in terms of GROWTH as â€Å"high-growth firms† and the lower 45 per cent as â€Å"low-growth firms†. Then we estimate our basic model for each sub-sample separately. The results are very similar to the ones reported in Table 6 (panel B), where we apply a similar methodology.As an additional robustness check, we use a third proxy for growth opportunities, a dummy variable that takes the value of 1 if the firm is a high-growth firm and 0 otherwise, and re-estimate the models 6 and 7 of Table 8. The definition used in order to distinguish between high-growth and low-gro wth firms is the following: Firms above the 55th percentile in terms of the variable GROWTH are called high-growth firms. Firms below the 45th percentile in terms of the variable GROWTH are called low-growth firms.Finally, firms between the 45th and 55th percentile are excluded from the sample. The results (not reported) are qualitatively similar to the ones reported in Table 8. For example, there is evidence for the existence of an interaction effect between executive ownership and growth opportunities but not for the one between short-term debt and growth opportunities. Also, we re-estimate the models reported in Table 8 after substituting the total salary paid to executive directors for the total remuneration package paid to executive directors.We are doing so given that the total remuneration package that is paid to managers includes several other components. For instance, the components of compensation structure have been increased in number during the last decade and may inclu de annual performance bonus, fringe benefits, stock (e. g. preference shares), stock options, stock appreciation rights, phantom shares and other deferred compensation mechanisms like qualified retirement plans (see Lynch and Perry, 2003 for an analytical discussion). Once more, the results do not change substantially.Finally, in Table 9 we substitute the annual sales to total assets with the ratio of SG&A expenses to total sales. As already mentioned earlier in the paper, this ratio can be used as a direct proxy for agency costs. Our results, as presented in Table 9, indicate that executive ownership, ownership concentration and total debt help reduce discretionary spending and, therefore, the agency conflicts between managers and shareholders. Sign and Davidson (2003) do not find any evidence to support these results. Also, we find that agency costs and growth opportunities are positively related i. . the coefficient of the variable GROWTH is positive and statistically significant to the 5 per cent statistical level. 23 Finally, our results support the existence of an interaction effect between growth opportunities and executive ownership. However, once more, our analysis does not indicate the existence of an interaction effect between short-term debt and growth opportunities. [Insert Table 9 here] 5. Conclusion In this paper we have examined the effectiveness of the alternative corporate governance mechanisms and devices in mitigating managerial agency problems in the UK market.In particular, we have investigated the impact of capital structure, corporate ownership structure, board structure and managerial compensation structure on the costs arising from agency conflicts mainly between managers and shareholders. The interactions among them and growth opportunities in determining the magnitude of these conflicts have also been tested. Our results strongly suggest managerial ownership, ownership concentration, executive compensation, short-term debt and, to s ome extent, bank debt are important governance mechanisms for the UK companies.Moreover, â€Å"growth opportunities† is a significant determinant of the magnitude of agency costs. Our results suggest that highgrowth firms face more serious agency problems than low-growth firms, possibly because of information asymmetries between managers, shareholders and debtholders. Finally, there is strong evidence that some governance mechanisms are not homogeneous but vary with growth oppo
