corruption and government size a disaggregated analysis using annual state level data over 1983 1987 this paper examines the effect of government size on corruption by public officials by including both demand and supply side incentives for engaging in corrupt practices our objectives are twofold first we assess the relationship between the incidence of corruption and overall measures of the size of the federal government and the state local sector in each state second we explore what kinds of government activities are more likely to be successful in deterring abuse of public office our results are generally supportive of becker s crime and punishment model regarding the primary focus of the paper our results show that government size in particular spending by state governments does indeed have a strong positive influence on corruption

optimal growth with many consumers abstract a method is described for constructing all pareto optimal allocations for a dynamic economy with many heterogeneous consumers under certainty in which both the technology and consumer preferences are recursive but preferences need not be additively separable over time optimal perfect foresight competitive equilibrium allocations are obtained through the study of a dynamic program for an economy with one consumption good sufficient conditions are given for the existence of a unique interior stationary distribution of consumption and wealth for a two person exchange economy sufficient conditions are given for the global asymptotic stability of the unique interior stationary point

the role of wages and auditing during a crackdown on corruption in the city of buenos aires abstract we study the prices paid for basic inputs during a crackdown on corruption in the public hospitals of the city of buenos aires argentina during 1996 97 we find a well defined negative effect on the measures used to capture corruption prices paid by hospitals for basic homogeneous inputs decrease by 15 percent during the first 9 months of the crackdown after this period prices increase but they are still 10 percent lower than those prevailing before the crackdown relative to the precrackdown period higher wages play no role in inducing lower input prices when audit intensity can be expected to be maximal during the first phase of the crackdown but have a negative and well defined effect when audit intensity takes intermediate levels the last phase of the crackdown controlling for fixed effects we find that the wage elasticity of input prices exceeds 20 these results are consistent with the standard model of bribes of gary becker and george stigler

the effect of group size on public good provision in a repeated game setting abstract the ability to cooperate in the provision of a pubic good is analyzed in a repeated game holding the level of provision fixed with quasi linear utility we find that the critical value of the discount parameter converges to 0 in the limit thus cooperation is feasible in a large market next we allow the level cooperation to be adjusted optimally as the group size increases both for a specific form of quasi linear utility and for cobb douglas utility in each case we find that there are admissible values of the discount parameter such that cooperation may be maintained in the limit

the impact of the corporate income tax evidence from state organizational form data abstract by taxing the income of corporate firms at a different rate than non corporate firms taxes can play an important role in a firm s choice of organizational form the sensitivity of the organizational form decision to tax rates provides a key indicator of the distortion created by the corporate income tax this paper uses new cross sectional data on organizational form choices across states compiled in the census of retail trade to estimate this sensitivity the results document a significant impact of the relative taxation of corporate to personal income on the share of real economic activity that is done by corporations and that the impact is many times larger than has been found in the previous empirical literature based on time series data the results show little impact however on the actual operations of firms such as their labor intensity wages and the like they do indicate that firms are able to exploit the progressivity of the corporate income tax system by dividing into numerous firms

a theory of collective reputations with applications to the persistence of corruption and to firm quality the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by his past behaviour and because his track record is observed only with noise by the group s past behaviour as well the paper thus studies the joint dynamics of individual and collective reputations and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality 1 collective reputations collective reputations play an important role in economics and the social sciences countries ethnic racial or religious groups are known to be hard working honest corrupt hospitable or belligerent some firms enjoy substantial rents from their reputations for producing high quality products some departments are reported to treat their faculty or students fairly the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by her past behaviour and because her track record is observed only with noise by the group s past behaviour as well the paper studies the joint dynamics of individual and collective reputations in a model in which current generations are progressively replaced by new ones and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature see section 2 for a detailed comparison with the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality let us spell out the building blocks of our theory in more detail a a group s reputation is only as good as that of its members each member is characterized by individual traits such as talent diligence or honesty past individual behaviour conveys information about these traits and generates individual reputations

an equilibrium queuing model of bribery it is sometimes argued that bribery is inefficient because bureaucrats may cause delays for attracting more bribes this hypothesis is examined in the context of a queue where customers having different values of time are ranked by their bribe payments to the queue s server the nash equilibrium strategies of the customers are derived it is shown that the server is unlikely to slow down the allocation process when bribery is allowed the model does not have stringent informational requirements and the equilibrium outcome minimizes the average value of time costs of the queue it also suggests a useful auctioning procedure

high corruption income in ming and qing china abstract we develop an economic model that explains historical data on government corruption in ming and qing china in our model officials extensive powers result in corrupt income matching land s share in output we estimate corrupt income to be between 14 and 22 times official income resulting in about 22 of agricultural output accruing to 0 4 of the population the results suggest that eliminating corruption through salary reform was possible in early ming but impossible by mid qing rule land reform may also be ineffective because officials could extract the same rents regardless of ownership high officials incomes and the resulting inequality may have also created distortions and barriers to change that could have contributed to china s stagnation over the five centuries 1400 1900s

corruption in russia abstractwe analyze the determinants of corruption in russia using law enforcement data on corruption incidents for a panel of 79 russian regions for the period 2004 13 we find that the relative salaries of bureaucrats determine corruption levels corruption declines as relative salaries rise yet at strongly diminishing rates furthermore we show that even very limited media freedom helps to curtail corruption other important determinants are the strength of law enforcement education levels and unemployment rates

public goods provision redistributive taxation and wealth accumulation this paper presents an extension of a static model of public goods provision with redistributional taxation as described by uler journal of public economics 93 3 4 pp 440 453 as a dynamic model of wealth accumulation intertemporal consumption and saving behavior strongly affect the relation between redistributive taxation and charitable contribution indeed the analyses presented herein reveal that more patience i e higher saving engenders a lower redistributional tax rate however the optimal redistributive tax rate is not zero because redistributive taxation improves the efficiency of providing public goods that are not improved by balanced growth this paper fills the gap separating static analysis and dynamic analysis and generalizes the results presented by static analysis

correlated payoffs in the inspection game some theory and an application to corruption the inspection game as formulated by tsebelis am polit sci rev 83 77 91 1989 has the counterintuitive implication that crime is unaffected by the magnitude of the penalty this paper demonstrates that to attain this outcome it is necessary to assume independence of enforcer and offender payoffs given correlated payoffs the comparative statics of the equilibrium yield an inverse relationship between crime and the severity of the sanction in an application we enrich the framework of tsebelis by adding corruption stages and show that this can imply such a correlation of payoffs another interesting finding is that harsher anticorruption measures can increase crime incentives

competition in bureaucracy and corruption abstract this paper studies the consequences of introducing competition between bureaucrats firms are supposed to invest into eliminating negative externalities of production while bureaucrats administer the process by issuing licences some bureaucrats are corrupt that is they issue a licence to any firm in exchange for a bribe the competition regime is found to create more ex ante incentives for firms to invest while the monopoly regime is better at implementing ex post allocation that is distributing the licences given the firms investment decisions additional results on the effect of punishments and bureaucrats rotation are provided

strategic transfers and private provision of public goods abstract this paper considers strategic monetary transfers between two agents when these contribute to a mutual public good if the agents differ in their contribution productivity then the less productive agent has an incentive to make large unconditional transfers to the more productive agent although agents move simultaneously in each stage of the game the less productive agent becomes a stackelberg leader furthermore the generic subgame perfect equilibrium is characterized by full specialization

the incidence and persistence of corruption in economic development abstract economic development and bureaucratic corruption are determined jointly in a dynamic general equilibrium model of growth bribery and tax evasion corruption arises from the incentives of public and private agents to conspire in the concealment of information from the government these incentives depend on aggregate economic activity which in turn depends on the incidence of corruption the model produces multiple development regimes transition between which may or may not occur in accordance with recent empirical evidence the relationship between corruption and development is predicted to be negative

redistributive taxation in a simple perfect foresight model abstract we investigate the redistributive potential of capital taxation in an intertemporal maximizing model of capital formation first even unanticipated redistributive capital taxation is severely limited in its effectiveness since it depresses wages second under any convergent redistributive tax policy which maximizes a paretian social objective the capital income tax will converge to zero independent of the factor supply elasticities these results are independent of workers holdings of capital

corruption in a model of growth political reputation competition and shocks the article tries to incorporate political corruption toplevel corruption into economic growth analysis we propose amicroeconomic framework an agent of the public sector who wantsto optimize his cash flow resulting from budget misappropriations will be highly sensitive to the instability related to his office the natural equilibrium for the politician will be to fall into a high political instability low growth trap in whichcorruption appears endemic however the control of corruption bysociety will be possible we consider a model in which alternativepoliticians compete with the incumbent politician but benefit from a common political reputation it is shown that this situation leads to dynamic collective reputation which should restrain misappropriationpractices this theoretical framework will be useful in defining a sustainable degree of political competition and inunderstanding the asymmetric effects of extrinsic shocks on thegrowth process

notes on bribery and the control of corruption abstract existing models of corruption that allow for bribery have ignored an important recursive problem when an auditor or a policeman bargains over a bribe with a person he has arrested he has to take into account the fact that he may in turn be caught for taking this bribe and be involved in a similar bargain but from the other side the purpose of this paper is to provide a simple model for capturing this recursion having done so it goes on to analyse some conditions for the control of corruption these turn out to be different from what conventional wisdom suggests

redistributive taxation in a small open economy this paper studies the effects of redistributing the tax burden across households on the current account the set up is a dynamic small open economy with infinitely lived households that have perfect foresight it is shown that the different speeds at which households adjust consumption levels to their long run values may cause nonmonotonic transient paths

corruption as a self fulfilling prophecy evidence from a survey experiment in costa rica an influential body of scholarship argues that corruption behaves as a selffulfilling prophecy the idea of this work is that levels of corruption emerge endogenously as a result of a society wide coordination game in which ther individual returns to corrupt behavior are a function of how disposed towards corruption the other members of society are perceived as being an empirical implication of this logic is that if one were to exogenously perturb beliefs about societal levels of corruption upward willingness to engage in corruption should increase as a consequence the current paper evaluates this claim by utilizing an information experiment embedded in a large scale household survey conducted in the gran area metropolitana gam of costa rica from october 2013 to april 2014 n 4200 changes in beliefs about corruption were induced via the random assignment of an informational display depicting the increasing percentage of costa ricans who have experienced or directly observed an act of corruption from 2006 to 2011 the paper finds that on average assignment to this display relative to the control condition increased the probability that a respondent would be willing to pay a bribe to a police officer by approximately 0 04 to 0 08 thereby providing supporting evidence for the self fulfilling prophecy hypothesis

institutional corruption and election fraud evidence from a field experiment in afghanistan w e investigate the relationship between political networks weak institutions and election fraud during the 2010 parliamentary election in afghanistan combining i data on political connections between candidates and election officials ii a nationwide controlled evaluation of a novel monitoring technology and iii direct measurements of aggregation fraud we find considerable evidence of aggregation fraud in favor of connected candidates and that the announcement of a new monitoring technology reduced theft of election materials by about 60 percent and vote counts for connected candidates by about 25 percent the results have implications for electoral competition and are potentially actionable for policymakers jel c93 d02 d72 k42 o17

on the economic incentives for taking bribes this paper presents an empirical analysis of the factors affecting bribe taking by public officials factors influencing the acceptance of bribes include the probability of being convicted severity of punishment government salary relative to private sector income the demonstration effect and the unemployment rate our results indicate that higher probability of being convicted discourages the acceptance of bribes as does more severe punishment low relative earnings high unemployment and the demonstration effect of aggregate advertising all lead to increased bribe taking

corruption and allocation efficiency abstract in this paper we investigate the possibility of allocation inefficiencies associated with corrupt practices specifically we consider the case in which two firms compete via bribery of a corrupt government official for a to be awarded project the economy may suffer allocation inefficiencies whenever there is some degree of discrimination given additional assumptions it is shown that the possibility of inefficient allocations increases as the degree of discrimination increases although empirical verification of discrimination is difficult due to the observational equivalence of an alternative imperfect knowledge model two possible explanations for the determination of discrimination coefficients indicate that it is a general phenomenon in competitive bribery games

tax transfer policies and the voluntary provision of public goods abstract the purpose of this paper is twofold first it extends previous models of non cooperative private funding of pure public goods by allowing both for distortionary taxation of private goods and for subsidies based on contributions to the public goods second it clarifies the type of behavioral and informational assumptions which are needed to insure neutrality of both lump sum and distortionary policies the analysis is developed in the context of fiscal federalism

corruption and development a review of issues in this paper we start with a discussion of some of the different denotations of the problem of corruption we then consider the ways in which the damaging consequences of corruption operate in a developing economy while not ignoring its possible redeeming features in some cases we pursue the question of why corruption is perceptibly so different in different societies and also persistent finally we examine the feasible policy issues that arise in this context

corruption in tax administration abstract we extend the game theoretic model of graetz reinganum and wilde 1986 to allow for corruption in tax administration in the presence of corruption audit rates are generally higher than in its absence in fact in the presence of corruption it is possible to sustain equilibria in which all returns are audited moreover when some auditors accept bribes it is possible for increases in the fine rate or the tax rate to reduce expected government revenue

the rate of time preference and dynamic economic analysis strong restrictions on the structure of preferences are a central feature in the received theory of intertemporal allocation in fact most of the modern literature concerned with capital theoretic problems represents preferences by a functional in which an additive utility function is discounted by a constant rate of time preference this specification is attractive because it is analytically tractable in dynamic models and it clearly delineates how tastes and opportunities interact to determine an economy s household s paths of consumption and capital formation however its rigid structure constancy of time preference severely limits the conclusions and explanatory power of the corresponding models this paper considers a class of utility functionals in continuous time which have the appealing feature that the rate of time preference depends systematically on an index of aggregate future consumption the more flexible structure embodied in these functionals leads to important generalizations and

weakly nonseparable preferences and distortionary taxes in a small open economy this paper examines the dynamic effects of distortionary taxes in a small open economy the employed utility function implies both endogenous rates of time preference and a tractable form of weak nonseparability between consumption and leisure weak nonseparability induces novel long run welfare and wealth effects of taxes and generates very different current account movements endogenous rates of time preference facilitate the examination of a tax on international borrowing and lending copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

on controlling crime with corrupt officials abstract this paper attempts to synthesize the recently developed strategic approach towards modeling corruption and the classical views the following propositions are sought to be proved a if reward schemes are introduced the classical and the strategic approaches yield similar results so far as controlling crime is concerned b with probability of detection being dependent on the effort of a corrupt official crime cannot be controlled and c in the context of an infinitely repeated game of crime the corrupt law enforcing agent might choose less bribes and lower effort level than the myopic optimal and hence would strategically pamper crime

corruption clubs empirical evidence from kernel density estimates a common finding of many analytical models is the existence of multiple equilibria of corruption countries characterized by the same economic social and cultural background do not necessarily experience the same levels of corruption in this article we use kernel density estimation techniques to analyse the cross country distribution of corruption particular emphasis will be given to the question whether the distribution of corruption shows more than one peak we find that most of the estimated densities exhibit twin peaks we also provide some evidence on the intra distribution dynamics and the persistence of corruption we find the group of countries classified within the two clubs to be very stable corruption is a highly persistent phenomenon substantial changes in the economic political and cultural environment of countries within the corruption club are required before a significant decline of corruption is to be expected

corruption as a gamble abstract in the following model of corruption a simple game is set up whose players are a government official granting a permit conditional on a test and a candidate requesting the permit the game is solved under different assumptions as to the information sets of the players perfect information asymmetric information and imperfect information on both sides in the latter case after characterizing the solution and presenting some important comparative statics results the paper moves on to show the emergence of multiple equilibria in corruption illustrating the interaction of corruption at different hierarchical levels of an administration

an axiomatic approach to the measurement of corruption theory and applications in this paper we demonstrate that the axiomatic measurement approach developed in the poverty and inequality literature can be usefully applied to the measurement of corruption we develop a conceptual framework for organizing corruption data and discuss several objective aggregate corruption measures consistent with axiomatic requirements we then provide an empirical application of the methodology and estimate the respective corruption measures for a sample of over 25 countries during the year of 2000 our empirical analysis reveals significant discrepancies between the country rankings generated by these measures and those provided by the corruption perception index cpi from transparency international to our knowledge this paper represents a first analysis of corruption measurement using an axiomatic framework

capital accumulation and the current account in a two country model abstract this paper examines the joint determination of international debt and capital accumulation in a two country model national rates of time preference are endogenous adjusting along an optimal path to come into equality with one another in the steady state the characteristics of short run current account dynamics are crucially linked to world capital accumulation and to a country s long run net external asset position steady state creditor countries tend to have current account surpluses during episodes of world output growth and vice versa for debtor countries this gives rise to possible non monotonic adjustment in the current account and consumption

corruption cooperation and endogenous time discount rates virtually all uses of repeated games tostudy of cooperation assume that people stime discount rates are exogenous andfixed here we offer an evolutionary gameembedded in a multi period model ofinvestment and consumption in whichindividual time discounts are determined bytheir convergence to values determined byevolutionary stable strategies oursubstantive motivation though iscorruption and its relationship to economicgrowth to understand the observedrelationship between levels of corruptionand economic indicators of social welfare we argue that corruption is a form ofcooperation that requires closeinterpersonal monitoring if we assume moreover that when people discount thefuture greatly the only sustainable formsof cooperation are those that allow forclose monitoring then our analysis can beinterpreted as a dynamic model of therelationship between corruption andinvestment

a theory of misgovernance this paper tries to explain why government bureaucracies are often associated with red tape corruption and lack of incentives the paper identifies two specific ingredients that together can provide an explanation the fact that governments often act precisely in situations where markets fail and the presence of agency problems within the government we show that these problems are exacerbated at low levels of development and in bureaucracies dealing with poor people we also argue that we need to posit the existence of a welfare oriented constituency within the government in order to explain red tape and corruption

how corruption may corrupt abstract the incidence of corruption appears to vary strongly across societies even for comparable activities the model highlights how the profitability of bureaucratic corruption may be related to its frequency and points toward a few mechanisms that can be used in explaining the stylized facts of varying incidence of corruption there might be multiple self fulfilling equilibria levels of corruption even when both supply and demand of corrupt acts are considered

business culture and tax evasion why corruption and the unofficial economy can persist abstract this paper shows that business and tax inspection culture can create multiple equilibria in bad equilibria high cheating and corruption increases in penalties or auditing can have perverse impacts and increase cheating the source of the multiple equilibria is the externalities created by business and tax inspection cultures as tax evasion and corruption become more common they become more acceptable and their cost is lowered a third externality that between firms and inspectors is the source of the perverse effect more cheating by firms is good for bribe taking inspectors and more bribe taking inspectors are good for cheating firms

a dynamic model of corruption deterrence abstract this paper presents a model of corruption deterrence with a simple overlapping generations structure built into it a crucial assumption is that when corruption becomes more prevalent in the economy it is harder to audit a corrupt official effectively it is shown that this assumption may give rise to several stationary equilibrium levels of corruption this possibility has been exploited to explain why sometimes a government may temporarily resort to an extremely severe deterrence policy and why the same deterrence scheme may imply quite different levels of corruption a case study is provided to give empirical support to the model

distribution and development in a model of misgovernance abstract this paper presents an analysis of bureaucratic corruption income inequality and economic development the analysis is based on a dynamic general equilibrium model in which bureaucrats are appointed by the government to implement a redistributive programme of taxes and subsidies designed to benefit the poor corruption is reflected in bribery and tax evasion as bureaucrats conspire with the rich in providing false information to the government in accordance with empirical evidence the model predicts a positive relationship between corruption and inequality and a negative relationship between corruption and development

adjustment costs in investment time preferences and the current account abstract this paper studies the effects of supply and demand shocks on the optimal investment and savings decisions of economic agents in a small open economy the two building blocks of the setup are adjustment costs in investment and a recursive time preference structure it is shown that the model can mimic certain stylized facts

a model of bureaucracy and corruption we analyze bureaucracy and corruption in a market with decentralized exchange and lemons exchange is modeled as a sequence of bilateral random matches agents have private information about the quality of goods they produce and can supplement trade with socially inefficient bribes bureaucracy is modeled as a group of agents who enjoy centralized production and consumption transaction patterns between the bureaucracy and the private sector are fully endogenous centralized production and consumption in the bureaucracy give rise to low power incentives for the individual bureaucrats as a result private agents might bribe bureaucrats whereas they do not bribe each other an equilibrium with corruption and an equilibrium without corruption can coexist we discuss some welfare implications of the model

capital income taxation in a growing open economy abstract the paper studies the dynamic macroeconomic effects of various forms of capital income taxation in a model of a small open economy with perfect mobility of financial capital and intertemporal optimization on the part of households and firms one of the noteworthy results is that the introduction of a low corporate income tax will not affect consumption in the long run but will simply lead to a replacement of shares by foreign financial assets in household portfolios it is also found that an anticipated investment tax credit can have and that an anticipated dividend tax will have contractionary effects on investment before they are introduced moreover it is shown that while an unanticipated dividend tax is neutral with respect to investment it will have real effects on consumption and net foreign assets in a growing economy

corruption and local democratization in indonesia the role of islamic parties indonesia has a tradition of corruption among local officials who harass and collect bribes from firms this paper examines whether corruption is affected by local democratization and by the party composition of local assemblies democratization occurred in 1999 and decentralization in 2001 we have firm level data for 2001 and 2004 the 2001 data benchmark corruption at the time of decentralization we find that corruption declines between 2001 and 2004 overall but much less so in districts with more secular party as opposed to islamic party representatives in district assemblies for a larger sample of districts correspondingly we find that corruption in 2004 is more in districts which voted more in favor of secular party representatives in the first elections in 1999 we argue that the effects seem to be causal over above any effects of changing religiosity and economic circumstances across districts

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

deals and delays firm level evidence on corruption and policy implementation times whether demands for bribes for particular government services are associated with expedited or delayed policy implementation underlies debates around the role of corruption in private sector development the grease the wheels hypothesis which contends that bribes act as speed money implies three testable predictions first on average bribe requests should be negatively correlated with wait times second this relationship should vary across firms with those with the highest opportunity cost of waiting being more likely to pay and facing shorter delays third the role of grease should vary across countries with benefits larger where regulatory burdens are greatest the data are inconsistent with all three predictions according to the preferred specifications ceteris paribus firms confronted with demands for bribes take approximately 1 5 times longer to get a construction permit operating license or electrical connection than firms that did not have to pay bribes and respectively 1 2 and 1 4

how corruptible are you bribery under uncertainty abstract we model corruption in a society as a result of bargaining for bribes between private citizens and public officials we investigate the role that incomplete information with respect to the intrinsic moral cost of one s potential corruption partner plays out in his or her propensity to engage in bribery and consequently the equilibrium level of corruption in the society we assume that the cost of engaging in corruption is subject to strategic complementarities which may lead to multiple corruption equilibria we find that corruption is lowest when potential bribers and potential bribees are uncertain regarding each other s corruptibility and have asymmetric bargaining powers our uncertainty result provides theoretical support in favor of anti corruption strategies such as staff rotation in public offices aimed at decreasing the social closeness of bribers and bribees our bargaining power result suggests that under uncertainty monopolistic public good provision has the same corruption reducing effect as competitive public good provision

international public goods and contribution productivity differentials abstract this paper investigates the impacts of productivity differentials in contributing to the public good on national welfare in the context of non cooperative voluntary provision of a pure public good a country with high productivity does not necessarily enjoy high welfare subsidizing the other country in a contribution game may lead to a strong paradoxical result while a lump sum transfer will lead to a weak paradoxical result we also explore the relationship between the price of the public good and the size of an open club in a multi club model

public goods provision and redistributive taxation abstract this paper studies the relationship between redistributive taxation and tax deductible charitable contributions redistribution has two opposite effects on voluntary giving the price of charitable giving decreases with the degree of redistribution and this has a positive effect on the total amount of giving substitution effect however redistribution leads to lower consumption for the contributors and therefore has a negative effect on contributions to the charity income effect the theoretical model developed in this paper demonstrates that under a general class of utility functions the substitution effect dominates the income effect hence charitable giving increases with the tax rate in purely egalitarian societies the public good is provided efficiently and the total welfare is maximized independent of the ex ante income inequality however the positive impact of taxation on charitable giving and welfare may disappear if individuals generate their income levels in anticipation of taxation and redistribution does not take into account the cost of effort

integrity for hire an analysis of a widespread customs reform abstract can governments improve bureaucratic performance by hiring integrity from the private sector in the past 2 decades a number of developing countries have hired private firms to conduct preshipment inspections of imports generating independent data on the value and tariff classification of incoming shipments i find that countries implementing such inspection programs subsequently experience large increases in import duty collections by contrast the growth rate of other tax revenues does not change appreciably additional evidence suggests that declines in falsification of import documentation are behind the import duty improvements the programs also lead to declines in undervaluation and misreporting of goods classifications historically this hired integrity appears to have been cost effective with improvements in import duty collections in the first 5 years of a typical inspection program amounting to 2 6 times the program s costs

corruption across countries and regions some consequences of local osmosis abstract large and persistent differences in corruption across comparable countries is a challenging research issue even more intriguing are such differences across regions within the same country because the typically considered socioeconomic and governance characteristics are generally more similar across such regions than across different countries this paper s principal theme is that individuals perceptions of their environments are influenced by the realities that they have faced in the past these perceptions affect their current and future actions which in turn influence the current and future realities an articulation and analysis of these dynamics yields significant observations concerning individuals behavior and societal outcomes

pareto optimal redistribution and private charity abstract when private charity exists and is motivated by utility interdependence a non pareto optimal outcome the free rider problem typically arises nevertheless incremental fiscal redistribution cannot achieve a paretian welfare improvement so long as private charity continues at positive levels donors respond to incremental fiscal redistribution by reducing their voluntary contributions by exactly a dollar for every dollar transferred in this way no net transfer is achieved unless incremental fiscal redistribution is pursued to the point where private contributions have been driven to zero alternatively a net transfer may be achieved by fiscal measures which affect donors marginal incentives to donate

does oil corrupt evidence from a natural experiment in west africa abstract this paper explores the oil discovery announcements in sao tome and principe 1997 1999 to assess the role of natural resources in determining corruption for this purpose we use a natural experiment framework which contrasts sao tome and principe to cape verde a control west african country sharing the same colonial past and important recent economic and political shocks our measurement is based on tailored household surveys we conducted in both island countries the unique survey instrument was retrospective and used personal histories to elicit memories from the respondents we analyze changes in perceived corruption across a wide range of public services and allocations we find clearest increases on vote buying education namely in the allocation of scholarships and customs ranging from 31 to 40 of the subjective scale we interpret these findings as symptoms of increased competition for core state resources
