mimicking portfolios and exact arbitrage pricing we characterize the sets of mimicking positions with returns that can serve in place of factors in an exact k factor arbitrage pricing relation for a set of n assets all of the sets are k dimensional nonsingular linear transformations of each other we interpret three examples of such transformations and discuss empirical considerations we provide conditions under which the mimicking positions can be expressed as portfolios and we characterize the relation between mimicking portfolios and the minimumvariance frontier

risk taking and taxation an alternative perspective abstract the analysis of risk taking and taxation has almost invariably been in a portfolio choice framework this paper presents the alternative perspective of an occupational choice framework where risk taking involves the additional element of discrete choice between safe and risky activities it is shown that the specification of equilibrium must of necessity have a general equilibrium character in this setting the paper develops rules for government intervention in the market equilibrium and analyses the effects of taxation on risk taking

biofuel investment in tanzania omissions in implementation abstract increasing demand for biofuels as a component of climate change mitigation energy security and a fossil fuel alternative attracts investors to developing countries like tanzania ample unused land is critical for first generation biofuels production and an important feature to attract foreign direct investments that can contribute towards agricultural modernization and poverty reduction initiatives despite the economic justifications the existing institutional and infrastructural capacities dictate the impacts of biofuels market penetrations furthermore exogenous factors like global recessionary pressure depressed oil prices below the level at which biofuel production were profitable in 2007 making tanzania s competitiveness and potential benefits questionable this paper investigates the extent that first generation jatropha based biofuels industry development in tanzania observed during fieldwork in kisarawe and bahi may fulfill policy objectives this paper argues that without strong regulatory frameworks for land investment management and rural development biofuel industrialization could further exacerbate poverty and food insecurity in tanzania the paper concludes with policy recommendations for first generation biofuel development while keeping in mind implications of second generation production since the topic is broad and multifaceted a multidisciplinary approach is used that includes political institutional and agricultural economics to analyze and conceptualize biofuel industry development and food security

labor unemployment risk and corporate financing decisions this paper examines the impact of labor unemployment risk on corporate financing decisions theory suggests that firms choose conservative financial policies partly as a means of mitigating worker exposure to unemployment risk using changes in state unemployment insurance benefit laws as a source of variation in the costs borne by workers during layoff spells we explore the connection between unemployment risk and the corporate financing decisions of public firms in the united states we find that increases in legally mandated unemployment benefits lead to increases in corporate leverage the impact of reduced unemployment risk on financial policy is especially strong for firms that have greater layoff separation rates labor intensity and financing constraints the estimated premium required to compensate workers for unemployment risk due to financial distress is about 57 basis points of firm value for a bbb rated firm these findings suggest that labor market frictions have a significant impact on corporate financing decisions

the rule of law and economic growth where are we summary it is widely assumed that the rule of law is essential for economic growth however the rule of law is clearly a multidimensional concept encompassing a variety of discrete components from security of person and property rights to checks on government and control of corruption we review the theory underlying these different causal mechanisms linking the rule of law to economic growth and provide an introduction to some outstanding measurement issues we find that the correlation among different components of the rule of law concept are not tight among developing countries and that some inferences about the effects of property rights protection may not be warranted

taxes and labor supply of high income physicians abstract we use the 1983 1985 physicians practice costs and income survey supplemented with federal and state tax rates to estimate the effect of variation in marginal tax rates on work hours for high income physicians we find that self employed physicians are much more sensitive to the marginal tax rate than would be suggested by previous labor supply studies while those who are employees have no discernible sensitivity to marginal tax rates

the debt equity choice when firms adjust their capital structures they tend to move toward a target debt ratio that is consistent with theories based on tradeoffs between the costs and benefits of debt in contrast to previous empirical work out tests explicitly account for the fact that firms may face impediments to movements toward their target ratio and that the target ratio may change over time as the firm s profitability and stock price change a separate analysis of the size of the issue and repurchase transactions suggests that the deviation between the actual and the target ratios plays a more important role in the repurchase decision than in the issuance decision

entrepreneurship and economic theory this article discusses economic theories of entrepreneurship drawing principally on work conducted in labour economics microeconomics macroeconomics and financial economics the article explains how incentives and constraints of various kinds affect occupational choices and entrepreneurial innovation as well as how entrepreneurial decisions affect macroeconomic performance implications for public policy are drawn

legal pluralism and decentralization natural resource management in mali summary much recent work on decentralized natural resource management has focused on the institutional arrangements that shape the balance of powers between central and local governments it has given comparatively less attention to relationships between local government and community level institutions in mali decentralization has superimposed modern legal institutions on community institutions the ambiguous relationships between them can undermine both the authority of nascent local governments and the performance of customary institutions legal pluralism the coexistence and interaction of multiple normative orders with different sources of legitimacy and authority helps explain the dynamic nature of local institutions under decentralization this article examines the experiences of three malian communities with decentralized natural resource management one maintains autonomy from government another engaged its local government and a third negotiated a multi stakeholder agreement a local convention they demonstrate that crafting workable relationships between communities and local government requires a pragmatic approach to negotiating and institutionalizing political space for innovation in self governance

human capital bankruptcy and capital structure we derive a firm s optimal capital structure and managerial compensation contract when employees are averse to bearing their own human capital risk while equity holders can diversify this risk away in the presence of corporate taxes our model delivers optimal debt levels consistent with those observed in practice it also makes a number of predictions for the cross sectional distribution of firm leverage consistent with existing empirical evidence it implies persistent idiosyncratic dierences in leverage across firms an important new empirical prediction of the model is that ceteris paribus firms with more leverage should pay higher wages

using national statistics to increase transparency of large land acquisition evidence from ethiopia the 2007 08 commodity price boom triggered a rush for land in developing countries yet many affected countries lacked the regulatory infrastructure to cope with such demand and reliable data on investors performance this study uses the example of ethiopia to show how simple improvements in administrative data collection can help to address this by i allowing assessment of the productivity of land use and taking measures to increase it ii comparing productivity between large and small farms to identify spillovers and ways to improve these and iii setting in motion a process of continuing improvement implications for global investment in this area are drawn out

shareholder value stakeholder management and social issues what s the bottom line we test the relationship between shareholder value stakeholder management and social issue participation building better relations with primary stakeholders like employees customers suppliers and communities could lead to increased shareholder wealth by helping firms develop intangible valuable assets which can be sources of competitive advantage on the other hand using corporate resources for social issues not related to primary stakeholders may not create value for shareholders we test these propositions with data from s p 500 firms and find evidence that stakeholder management leads to improved shareholder value while social issue participation is negatively associated with shareholder value copyright 2001 john wiley sons ltd

tax evasion and labor markets abstract concern with revenue losses inequities and inefficiency that may result from tax evasion has produced a number of formal analyses of taxpayer dishonesty most of this work has concentrated on the behavior of individual evaders and has ignored the interaction between evasion and labor market equilibrium to remedy this our analysis uses a model with two labor markets which differ in the potential for evasion to examine how changes in various tax parameters affect evasion and labor market equilibrium we also simulate the effect of switching from a proportional to a progressive tax system in order to evaluate the well known claim that progressivity encourages evasion

determinants of target capital structure the case of dual debt and equity issues abstract we examine whether market and operating performance affect corporate financing behavior because they are related to target leverage our focus on firms that issue both debt and equity enhances our ability to draw inferences consistent with dynamic trade off theories dual issuers offset the deviation from the target resulting from accumulation of earnings and losses our results also imply that high market to book firms have low target debt ratios on the other hand consistent with market timing high stock returns increase the probability of equity issuance but have no effect on target leverage

asymmetric information occupational choice and government policy a model of credit markets under asymmetric information is proposed in which individuals differ in abilities that are valued in both entrepreneurship and paid employment unlike the heterogeneous ability model of de meza and webb 1987 over investment is not inevitable under investment and credit rationing can occur instead this result depends on the novel possibility of there being greater separation of types in paid employment than in entrepreneurship the model allows individuals to be monitored in both occupations and permits derivation of the conditions under which the novel possibility holds the role of corrective government policies is also discussed

optimal linear income taxation in models with occupational choice the purpose of this paper is to investigate the implication of occupational choice for linear income taxation occupational choice is restricted to entrepreneurship versus wage earning different settings are considered concerning the introduction of uncertainty and that of individuals heterogeneity in ability or risk aversion for each setting an optimal tax formula is derived and shown to be made up of various components pertaining to insurance redistribution and efficiency

employee well being firm leverage and bankruptcy risk employees of liquidating firms are likely to lose income and non pecuniary benefits of working for the firm which makes bankruptcy costly for employees this paper examines whether firms take these costs into account when deciding on the optimal amount of leverage we find that firms with leading track records in employee well being significantly reduce the probability of bankruptcy by operating with lower debt ratios moreover we observe that firms with better employee track records have better credit ratings even when we control for differences in firm leverage

the effect of capital structure on a firm s liquidation decision abstract a firm s liquidation can impose costs on its customers workers and suppliers an agency relationship between these individuals and the firm exists in that the liquidation decision controlled by the firm as the agent affects other individuals the customers workers and suppliers as principals the analysis in this paper suggests that capital structure can control the incentive conflict problem of this relationship by serving as a pre positioning or bonding mechanism appropriate selection of capital structure assures that incentives are aligned so that the firm implements the ex ante value maximizing liquidation policy

sub rosa resistance and the politics of economic reform land redistribution in post soviet ukraine this article examines obstacles to economic reform in ukraine s transition to a market based economy existing explanations for failures of reform in postcommunist states privilege societal actors as in the case of przeworski s j curve or state actors acting in a private rent seeking capacity as in hellman s partial reform equilibrium other explanations focus on weak state capacity however there is evidence to suggest that some groups of individuals who stall or halt market reforms may do so in their capacity as state actors their resistance to reform may be sub rosa state actors may comply with formal institutional requirements of reform even as they seek to preserve the status quo this tendency is evident in the privatization of land the focus of this article this article proposes an explanation for reform failures which suggests that some resistance to economic liberalization may derive from the efforts of state actors to protect the public good

entrepreneurship and personal income tax evidence from canadian provinces this paper employs the dynamic panel estimation method to investigate the effects of the top personal income tax rate on entrepreneurship as proxied by the employer business entry rate using data from canadian provinces over the period 1984 2015 the empirical findings of this paper show that the top income tax rate has a negative and statistically significant effect on entrepreneurship both in the short and long term according to the preferred estimate of this study a one percentage point increase in the top statutory marginal income tax rate is associated with a 0 13 percentage point decrease in the business entry rate in the short term and a 0 41 percentage point decrease in the long term based on the long term results on average a province that raises its top personal income tax rate by one percentage point can expect to have about 405 fewer new employer businesses enter its economy this is a significant loss for an economy that has been experiencing a decline in entrepreneurship for a long time the key findings of this paper are robust to various sensitivity checks

how investor portfolios shape regulatory outcomes privatized infrastructure after crises summary many developing countries privatized utilities during the 1990s their weak institutional environments however make them prone to crises that generate incentives for governments to renege on contractual commitments to investors to understand variation in post crisis regulatory outcomes in such contexts scholars must consider investors prior choices regarding portfolio structure investors facing high reputational costs from exit are more likely to remain following expropriation and those holding diverse assets in their contract jurisdiction to secure compensation these factors account for significant unexplained within sector and subnational variation for which we provide qualitative and quantitative evidence from argentina s water and electricity sectors following the 2001 crisis

are firms underleveraged an examination of the effect of leverage on default probabilities a commonly held view in corporate finance is that firms are less leveraged than they should be given the potentially large tax benefits of debt in this paper i study the effect of firms leverage on default probabilities as represented by the firms ratings using an instrumental variable approach i find that the leverage s effect on ratings is three times stronger than it is if the endogeneity of leverage is ignored this stronger effect results in a higher impact of leverage on the ex ante costs of financial distress which can offset the current estimates of the tax benefits of debt

choice of occupation tax incidence and piecemeal tax revision a model is presented where workers move between two different occupations in response to economic incentives which are distorted by an income tax wages assume equilibrium values which are affected by the tax parameters incidence and welfare effects of small tax revisions are analyzed with particular attention to the role of tax induced wage changes it is demonstrated that within the economic setting of the model such wage effects may be neglected in assessments of piecemeal tax revisions

tax evasion and the size of the underground economy abstract the theoretical literature on the relationship between the tax system and the underground economy is extended using a model similar to the one examined by watson journal of public economics 1985 27 231 246 in which tax evasion is possible in one sector of the economy but is impossible in the other we prove that a rise in the tax rate increases decreases the number of agents in the sector in which tax evasion is possible if preferences exhibit increasing decreasing relative risk aversion we also use our model to investigate the relationship between the tax rate and the total amount of tax evaded

swimming upstream local indonesian production networks in globalized palm oil production summary when agricultural commodities in developing countries experience an economic boom they offer potential pathways out of poverty while creating environmental and social problems while recent research provides insights into the governance of international supply chains it provides less analysis of the local production networks creating critical problems indonesia is now the world s largest exporter of crude palm oil this paper analyses processes of oil palm development in three oil palm districts it considers how policy models regime interests and agribusiness strategies shape local production networks generate local outcomes and affect the possibilities of tackling issues associated with this boom

federalism as a commitment to reserving market incentives the authors advance a new perspective in the study of federalism their approach views federalism as a governance solution of the state to credibly preserving market incentives market incentives are preserved if the state is credibly prevented from compromising on future economic success and from bailing out future failures the salient features of federalism decentralization of information and authority and interjurisdictional competition help provide credible commitment or these purposes in addition the authors suggest that some federalism are self sustaining

the legal environment and incentives for change in property rights institutions summary land conflicts in many parts of the world indicate pressures for change in the property rights institutions governing land acquisition and land use whether or not institutional change occurs depends on the incentives and capacities of political actors this article argues that the legal environment is one factor influencing incentives for institutional change three case studies of land governance in southeast asia s palm oil industry illustrate three types of legal environment rule by law legalism legal pluralism and lawlessness or routinized illegality the cases show that the legal environment shapes modes of resistance to property reallocations in the palm oil industry rule by law legalism supports legalized modes of resistance through the court system in contrast legal pluralism and lawlessness favor the use of political strategies to contest property reallocations the mode of resistance in turn determines whether actors acquiring property have incentives to gain legal cover or whether investing in political resources is more rewarding although the effectiveness of resistance is largely determined by the distribution of political resources the mode of resistance helps explain whether there is demand for property rights institutions that offer generalized legal certainty in property protection path dependence arising from the legal environment therefore influences the direction of institutional change

secure property as a bottom up process firms stakeholders and predators in weak states how do property rights become secure how does rule of law take hold in an economy the author uses an original survey of 516 firms in russia and ukraine as well as interview based case studies to reexamine these fundamental issues of political economy most states in the developing world lack the requisite time horizons and institutional capacity to make the credible commitments emphasized in the literature in this context the author argues that firms can enforce their property rights without resort to mafias by forming alliances with stakeholders such as foreign actors community residents and labor these stakeholders can impose costs on the potential aggressors through diverse political strategies allowing firms to defend their property rights not only from private predators but also from the state the article evaluates this bottom up theory of secure property rights against existing state based theorizing

governance institutions resource rights regimes and the informal mining sector regulatory complexities in indonesia summary this study examines how shifting resource governance regimes affect labor inequities in the small scale mining sector in indonesia it focuses on the implications of governance decentralization processes and mining regulation reforms for indigenous and migrant populations who rely on informal unlicensed mining for income in central kalimantan while the findings illustrate the territorially uneven impacts of recent reforms they highlight how dominant paradigms that prioritize the enforcement of property rights schemes have contributed to problems of livelihood insecurity and poor environmental governance the article urges for more nuanced attention to contested articulations of power as well as local resource rights and institutional arrangements to assist rural communities in reversing marginalization

income shifting as income creation abstract income shifting arises as one of the key questions when thinking about the design of a tax system as a whole we study a simple economy involving a benevolent policy maker and a population of agents differing in terms of productivities labor supply elasticities and shifting costs paying special attention to the cost structure of income shifting we highlight that when people who shift easily along the extensive margin are also more elastic in labor supply giving them a lower tax rate is a good thing and the government should not necessarily combat income shifting this mechanism may be compared to third degree price discrimination in industrial organization and works as a form of endogenous tagging we explore this possibility numerically before showing that our results derived for a policy maker optimally adjusting two linear tax instruments carry over when two fully non linear taxes are potentially available

good jobs bad jobs and redistribution we analyse the question of optimal taxation in a dual economy when the policy maker is concerned about the distribution of labour income income inequality is caused by the presence of sunk capital investments which creates a good jobs sector due to the capture of quasi rents by trade unions with strong unions and high planner preference for income equality the optimal policy is a combination of investment subsidies and progressive income taxation if unions are weaker the policy maker may instead choose to tax investment

tax progressivity and self employment evidence from canadian provinces we examine the effects of personal income tax progressivity in the sense of rising marginal income tax rate on self employment the impacts of income tax progressivity on self employment depend on the relative effects of taxing success and the presence of tax evasion opportunities empirical estimates using canadian provincial data for the period 1979 2006 indicate that there is a negative association between income tax progressivity and self employment this suggests that the adverse impact of income tax on entrepreneurial risk taking outweighs the tax evasion opportunities for the self employed an important implication of our results is that a reduction in income tax progressivity encourages self employment the empirical estimates are robust to the various sensitivity checks

explaining international variations in self employment evidence from a panel of oecd countries organisation for economic cooperation and development oecd data from 1972 to 1996 reveals substantial differences in the levels and trends of self employment rates across countries this article uses recently developed panel integration and cointegration techniques to explore the determinants of aggregate self employment rates we find that within the panel self employment rates are positively and significantly related to personal income tax rates and negatively and significantly related to the unemployment benefit replacement rate this accords a central role to government tax and transfer policies in contrast to nonrobust influences from macroeconomic variables which have been widely used in previous studies

redistributive taxation in the roy model we consider optimal redistribution in a model where individuals can self select into one of several possible sectors based on heterogeneity in a multidimensional skill vector we show that when the government does not observe the sectoral choice or underlying skills of its citizens the constrained pareto frontier can be implemented with a single non linear income tax we derive formulas for this optimal tax schedule if sectoral inputs are complements a many sector model with self selection leads to optimal income taxes that are less progressive than the corresponding taxes in a standard single sector model under natural conditions however they are more progressive than in a multi sector model without occupational choice or without overlapping wage distributions as in stiglitz 1982

coordination commitment and enforcement the case of the merchant guild we interpret historical evidence in light of a repeated game model to conclude that merchant guilds emerged during the late medieval period to allow rulers of trade centers to commit to the security of alien merchants the merchant guild developed the theoretically required attributes secured merchants property rights and evolved in response to crises to extend the range of its effectiveness contributing to the expansion of trade during the late medieval period we elaborate on the relations between our theory and the monopoly theory of merchant guilds and contrast it with repeated game theories that provide no role for formal organization

original sin good works and property rights in russia are property rights obtained through dubious means forever tainted with original sin or can right holders make their ill gotten gains legitimate by doing good works this is a critical question for developing and transition countries where privatization is often opaque and businesspeople may receive property but remain unwilling to use it productively due to concerns about the vulnerability of their rights to political challenge using a survey of 660 businesspeople conducted in russia in 2005 the author finds that the original sin of an illegal privatization is difficult to expunge contrary to a coasian view of privatization property rights transferred through a legally questionable privatization are seen as illegitimate long after privatization businesspeople however can improve the legitimacy of property rights by doing good works such as providing public goods and using their assets well finally managers who provide public goods for their region are more likely to invest in their firms than those who do not this suggests a possible political rationale for the provision of public goods by private firms these findings have implications for studies of privatization property rights and business state relations in transitions and developing countries

inherent inequality and the optimal graduation of marginal tax rates in most countries marginal tax rates increase with income this is at variance with the results of the optimal income taxation literature whose numerical calculations have established the presumption that optimal marginal tax rates should decline with income have the existing results of optimal income tax literature therefore established a presumption that the observed pattern is suboptimal the object of this paper is to attempt to answer this question the numerical calculations that followed mirrlees s 1971 pioneering contribution tried many variations on his basic parametrisation including different preference structures and different functional forms however so far as we are aware most of the reported results maintain his basic assumption of a log normal distribution of abilities or wages with a standard deviation of logs of 0 39 mirrlees 1971 himself appealed the work of lydall 1969 for this figure but it has become the industry standard we show in this paper that departures from this assumption in particular increases in inherent inequality can alter the qualitative pattern of optimal marginal tax rates dramatically contrary to the currently available calculations we show that the optimal graduation can indeed be such that marginal tax rates increase for the majority of the population which is consistent with the observed pattern but that there continues to exist a significant income range at the top where marginal tax rates decline which of course is counter to the observed pattern

income tax evasion labour supply and the equity efficiency tradeoff abstract this paper is an attempt to incorporate tax evasion into the analysis of optimum income taxation a model of variable labour supply with tax evasion is used to derive supply functions for labour in regular and irregular markets given taxpayer behaviour the government chooses tax rates penalties and the probability of detection to maximize a utilitarian social welfare function the results consist in the derivation of a formula for the optimum marginal tax rate and a characterization of the factors determining the choice between the penalty rate and the probability of detection as instruments for the control of tax evasion

the mystery of capital formation in sub saharan africa women property rights and customary law summary economists such as hernando de soto have argued that clearly defined property rights are essential to capital formation and ultimately to economic growth and poverty alleviation this article traces two impediments to the clear definition of property rights in the african context customary law and the status of women both of these issues interfere with the attempt of african countries to rearticulate property law with the goal of capital formation constructive attempts to define property rights must address the problem of enforcement in under resourced environments where changes may not be welcomed

the distribution of self employment income in the united kingdom 1976 1991 this paper examines the pattern of uk self employment income inequality between 1976 and 1991 and develops a simple model of the size distribution inequality measures are related to the parameters of this distribution whose economic determinants are explained it is found that the principal cause of rising self employment income inequality over this period was a substantial increase in the heterogeneity of the self employed themselves in contrast the increased numbers engaged in self employment over the period seems to have had no discernible effect on inequality via the parameters of the self employment income distribution

businesspeople in elected office identifying private benefits from firm level returns do businesspeople who win elected office use their positions to help their firms business leaders become politicians around the world yet we know little about whether their commitment to public service trumps their own private interests using an original dataset of 2 703 firms in russia i employ a regression discontinuity design to identify the causal effect of firm directors winning seats in subnational legislatures from 2004 to 2013 first having a connection to a winning politician increases a firm s revenue by 60 and profitability by 15 over a term in office i then test between different mechanisms finding that connected firms improve their performance by gaining access to bureaucrats and not by signaling legitimacy to financiers the value of winning a seat increases in more politically competitive regions but falls markedly when more businesspeople win office in a convocation politically connected firms extract fewer benefits when faced with greater competition from other rent seekers

determinants of biofuel oriented land acquisitions in sub saharan africa abstract the recent surge of investors interest for african land has triggered the debate about the drivers and effects of the so called land grabbing after a review of the relationship between investment in land and biofuel development in sub saharan africa we contribute to the existing literature in four dimensions we use the updated version of land matrix whose potentialities are currently underexploited we concentrate on land deals for cultivating biofuel crops which are emblematic of the food land energy nexus we focus on fdi to the african continent the most targeted region for land grabbing finally we delve deeper into the influence of institutional quality by testing the role of different institutional dimensions we find that abundance of water resources and general business conditions security and regulatory quality facilitate the investment in land for biofuels as for land governance what matters is the strength and security of land tenure rights rather than the type of tenure system

contemporary processes of large scale land acquisition in sub saharan africa legal deficiency or elite capture of the rule of law summary growth of emerging economies policy commitments to biofuels and volatility in commodity prices have contributed to a marked increase in the pace and scale of foreign direct investment in land based enterprises in the global south this paper explores the relationship between policy and practice associated with customary rights protections in the context of large scale land acquisitions through a document review and case study analyses from ghana mozambique tanzania and zambia findings point to the difficulty of safeguarding customary rights even in countries providing best practice legal protections and point to the fundamental role of human agency in shaping outcomes

environmental corporate social responsibility and financial performance disentangling direct and indirect effects abstract this paper assesses the impact of environmental corporate social responsibility ecsr on corporate financial performance cfp measured by roa and tobin s q we show that the relationship between firms return on assets roa and ecsr strengths and concerns is negative and statistically significant we also show that firms tobin q and ecsr strengths and concerns are negatively correlated in a statistically significant way however accounting for the interaction between firms environmental efforts and r d yields a different perspective while the direct impact of ecsr on cfp is still negative the interaction of ecsr and r d has a positive and significant impact on it ecsr strengths and concerns harm cfp since they are perceived as a potential cost however this csr activity fosters r d efforts of firms which generates additional value indirect effect

credible commitment and property rights evidence from russia most managers said that state arbitration courts did not work badly in disputes with other businesses but few expected these courts to protect their rights in disputes with state officials more importantly managers who expressed confidence that state arbitration courts could constrain state officials invested at higher rates even controlling for the perceived effectiveness of state institutions thus tightening constraints on state agents can increase the security of property and bolster state capacity these results generate insights into debates on the role of state in the economy the origins of secure property rights the nature of state capacity the importance of informal institutions and the process of legal reform

tax evasion and occupational choice this paper is concerned with the combined effect of tax compliance and tax audit policy on the occupational choice of individuals and on public policy objectives such as tax revenue total production and social welfare individuals are assumed to have a choice between riskless work and a risky entrepreneurial occupation they are only differentiated according to their attitudes towards risk more risk averse individuals go into the safe occupation and less risk averse people become entrepreneurs tax evasion is only accessible to the latter and therefore its control tends to discourage risk taking whether control of tax evasion is desirable for the economy as a whole depends on the objective function of the government it is shown that tax audit policy has conflicting effects on tax revenue per capita income and social welfare these conflicts are illustrated through a numerical example in this paper the emphasis is placed on the clarity and the simplicity of the presentation so as to argue that even though the tax schedule can hardly be differentiated across individuals tax evasion and its control can be used by policymakers to introduce variability in the individual s tax treatment

the optimal linear taxation of employment and self employment incomes abstract this paper models optimal linear taxation when occupational choice and labour supply are endogenous workers choose between paid employment self employment and unemployment self employment incomes are risky and employees may be involuntarily laid off calibrating the model to the uk economy the optimal tax solution involves relatively high taxation with substantial redistribution and a higher nominal but not effective marginal tax rate imposed on the self employed than on employees the implications of making unemployment benefits as well as tax rates endogenous are also analysed and robustness checks are performed

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
