first price auction implements efficient investments abstract this note shows that the first price auction fully implements efficient investments when agents make not only ex ante but also ex post investments the essential assumptions of our model are that i each agent can invest before and after participating in the auction under the same cost function and ii the cost functions are common knowledge among agents in any equilibrium of our model the most efficient agent always wins and makes the efficient level of investment

the excise tax effects of the property tax abstract this paper constructs a theory of how differences across regions in property tax rates affect product prices and factor prices for a model where labor and capital are perfectly mobile between regions it is shown that consumers residing in different regions face the same nontraded good prices even when property tax rates differ across regions

efficient non contractible investments in large economies abstract do investors making complementary investments face the correct incentives especially when they cannot contract with each other prior to their decisions we present a two sided matching model in which buyers and sellers make investments prior to matching once matched buyer and seller bargain over the price taking into account outside options efficient decisions can always be sustained in equilibrium we characterize the inefficiencies that can arise in equilibrium and show that equilibria will be constrained efficient we also show that the degree of diversity in a large market has implications for the extent of any inefficiency journal of economic literature classification numbers c78 d41 d51

why is corruption less harmful to income inequality in latin america summary conventional wisdom says corruption is bad for income inequality but recent research on latin america finds a trade off between corruption and inequality and suggests this is due to the large informal sector in the region using data on a large sample of countries we find that the informal sector impacts the link between corruption and inequality in particular the marginal impact of corruption becomes negative once the informal sector becomes large this is true in latin america and more generally corruption reducing policies should be accompanied by measures that help displaced informal sector workers

decentralization and corruption evidence from u s federal transfer programs while some recent evidence suggests that more decentralization is associated with reduced corruption no empirical work has examined whether different types of decentraliz ation have differential effects on corruption the theoretical literature has emphasized that expenditure decentralization will only be effective if accompanied by the devolution of rev enue generation to local governments in this paper we examine this hypothesis empirically by studying the mismatch between revenue generation and expenditure in u s states larger federal transfers are associated with higher rates of conviction for abuse of public office supporting the theory that soft budget constraints created by federal transfers are potentially problematic

corruption in america abstract we use a data set of federal corruption convictions in the u s to investigate the causes and consequences of corruption more educated states and to a smaller degree richer states have less corruption this relationship holds even when we use historical factors like congregationalism in 1890 as an instrument for the level of schooling today the level of corruption is also correlated with the level of income inequality and racial fractionalization and uncorrelated with the size of government there is a weak negative relationship between corruption and economic development in a state these results echo the cross country findings and support the view that the correlation between development and good political outcomes occurs because education improves political institutions

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

contractual solutions to the hold up problem this paper considers a general version of the hold up problem where n agents first make relation specific investments and then must agree on some collective action it is shown that first best solutions exist under a variety of different assumptions about the nature of information asymmetries

economies of scale and barriers to entry dixit has recently presented a model in which established firms select capacity to discourage entry but cannot employ threats they would not rationally execute after entry entry deterrence in a slight modification of this model involves the classical limit price output under linear or concave demand however the capital cost of a firm of minimum efficient scale is an upper bound on the present value of the monopoly profit stream that can be shielded from entry it is argued that this suggests the general unimportance of entry barriers erected by scale economies

inefficiencies from metropolitan political and fiscal decentralization failures of tiebout competition we examine the welfare effects of provision of local public goods in an empirically relevant setting using a multi community model with mobile and heterogeneous households and with flexible housing supplies we characterize the first best allocation and show efficiency can be implemented with decentralization using head taxes we calibrate the model and compare welfare in property tax equilibria both decentralized and centralized to the efficient allocation inefficiencies with decentralization and property taxation are large dissipating most if not all the potential welfare gains that efficient decentralization could achieve in property tax equilibrium centralization is frequently more efficient an externality in community choice underlies the failure to achieve efficiency with decentralization and property taxes poorer households crowd richer communities and free ride by consuming relatively little housing thereby avoiding taxes copyright oxford university press

unforeseen contingencies and incomplete contracts we scrutinize the conceptual framework commonly used in the incomplete contract literature this literature usually assumes that contractual incompleteness is due to the transaction costs of describing or of even foreseeing the possible states of nature in advance we argue however that such transaction costs need not interfere with optimal contracting i e transaction costs need not be relevant provided that agents can probabilistically forecast their possible future payoffs even if other aspects of the state of the nature cannot be forecast in other words all that is required for optimality is that agents be able to perform dynamic programming an assumption always invoked by the incomplete contract literature the foregoing optimality result holds very generally provided that parties can commit themselves not to renegotiate moreover we point out that renegotiation may be hard to reconcile with a framework that otherwise presumes perfect rationality however even if renegotiation is allowed the result still remains valid provided that parties are risk averse

investment incentives in procurement auctions this paper investigates firms incentives to invest in cost reduction in the first price sealed bid auction a format largely used for procurement two central features of the model are that we allow firms to be heterogeneous and that investment is observable we find that firms will tend to underinvest in cost reduction because they anticipate fiercer head on competition using the second price auction as a benchmark we also find that the first price auction will elicit less investment from market participants and that this is socially inefficient these results have implications for market design when investment is important different market institutions provide different incentives for firms to reduce costs acquire information expand and so on in short to undertake any activity that affects their competitive positions accordingly the performance of these market institutions should be judged not only from a static perspective taking firms competitive positions as given but also from a dynamic perspective auction markets are a natural competitive environment to study because there is a clear sense in which we can design such markets by choosing appropriate rules for competition in this paper we study how the first price auction fpa a format commonly used for procurement affects firms incentives to invest in cost reduction many procurement markets are characterized by a small number of participants heterogeneity among firms and low rates of turnover therefore it is interesting to investigate to what extent the format used for the auction contributes to these characteristics the basic ingredients of our model are as follows there are n firms and one of them has the opportunity prior to the auction to make an investment we model this investment as an improvement in the ex ante distribution of costs for this firm the main question we ask is what are the firm s incentives to invest given that this investment is observed by its competitors clearly the benefits of such investment depend on how the firm s competitors react in other words to determine the firm s incentive to invest we need to compare the equilibrium at the procurement stage if it makes this investment and if it does not in section 3 we derive new comparative statics results for the fpa we find that after the investment the investor s opponents will bid collectively more aggressively this result holds generally when there are only two bidders or when the investor s opponents are symmetric proposition 1 otherwise a sufficient condition is that investment changes market leadership proposition 2 in the language of industrial organization investment has a negative strategic effect in the fpa this erodes 1

the implications of competition among jurisdictions does tiebout need politics the paper investigates whether compensation among local jurisdiction is by itself sufficient to ensure efficient provision of local public goods jurisdictions have fixed boundaries and each has an entrenched government with the power to tax and supply the public good residents can move costlessly among jurisdictions it is shown that competition among numerous jurisdictions is not sificient to guarantee public sector efficiency though residents can vote with their feet land is immobile hence governments can unsurp some land rents for their own ends increasing the number of jurisdictions limits but cannot completely eliminate the ability to exercise discretionary governmental power

auctioning incentive contracts this paper draws a remarkably simple bridge between auction theory and incentive theory it considers the auctioning of an indivisible project among several fi rms the firms have private information about their future cost at th e bidding stage and the selected firm ex post invests in cost reduct ion the authors show that 1 the optimal auction can be implemented by a dominant strategy auction that uses information about both the first bid and the second bid 2 the winner faces a linear incenti ve contract 3 the fixed transfer to the winner decreases with his announced expected cost and increases with the second lowest announce d expected cost and 4 the share of cost overruns borne by the winn er decreases with the winner s announced expected cost copyright 1987 by university of chicago press

causes and effects of corruption what has past decade s empirical research taught us a survey corruption has fierce impacts on economic and societal development and is subject to a vast range of institutional jurisdictional societal and economic conditions it is this paper s aim to provide a reassessment and a comprehensive state of the art survey of existing literature on corruption and its causes and effects a particularly strong focus is put on presenting and discussing insights resulting from empirical research and contrasting recent with older findings

a comparative study of inequality and corruption this article argues that income inequality increases the level of corruption through material and normative mechanisms the wealthy have both greater motivation and more opportunity to engage in corruption whereas the poor are more vulnerable to extortion and less able to monitor and hold the rich and powerful accountable as inequality increases inequality also adversely affects social norms about corruption and people s beliefs about the legitimacy of rules and institutions thereby making it easier for them to tolerate corruption as acceptable behavior this comparative analysis of 129 countries using two stage least squares methods with a variety of instrumental variables supports the authors hypotheses using different measures of corruption the world bank s control of corruption index and the transparency international s corruption perceptions index the explanatory power of inequality is at least as important as conventionally accepted causes of corruption such as economic development the autho

risky local tax bases risk pooling vs rent capture abstract when a jurisdiction s land or other fixed resources are owned by non residents its residents have an incentive to capture the non residents rents by imposing confiscatory taxes when different jurisdictions are subject to less than perfectly correlated risks such taxes destroy the benefits of risk pooling that cross ownership of property otherwise permits if jurisdictions must use property taxes i e taxes on both immobile land and mobile capital instead of taxes on land alone they will compete for mobile capital by keeping tax rates low if capital is sufficiently substitutable for immobile factors tax rates will be low enough to achieve greater effective diversification of risks and higher welfare

renegotiation design with unverifiable information this paper considers a buyer seller relationship with observable but unverifiable investments and or random utility parameters in such situations it is known that contract renegotiation may prevent the implementation of first best outcomes in this paper we show however that efficient investments and optimal risk sharing can typically be achieved provided the initial contract is able to monitor the ex post renegotiation process specifically we focus on the following two features of renegotiation design first default options in case renegotiation breaks down second the allocation of all bargaining power to either contracting party moreover we show that these two features can be obtained in standard rubinstein bargaining games through contractual provisions such as specific performance clauses and penalties for delay or equivalently financial hostages refundable without interest

optimal auction design and r d abstract an indivisible object is to be procured through bidding from one of two prospective suppliers firms decide whether to invest in cost reduction before the bidding the procurer commits to a mechanism ahead of investment decisions by firms if the procurer can charge entry fees that may be discriminatory a sealed bid second price auction uniquely implements the first best outcome and is optimal for the buyer revenue equivalence holds when first best investments are symmetric however it breaks down when first best investments are asymmetric without entry fees the procurer may want to bid discriminate between ex ante identical firms to induce the favored firm to invest and become strong while the unfavored firm not to invest and stay weak this result runs counter to the earlier findings on discrimination in procurement auctions without pre contract r d the principal favors the weaker agent to induce stronger bid competition

strategic tax competition with a mobile population espanoleste articulo analiza un modelo estrategico de competicion de impuestos donde el capital y los identicos consumidores pueden migrar entre jurisdicciones los resultados obtenidos son comparados con los resultados del modelo tradicional de competencia tributaria donde la poblacion es inmovil ademas de los efectos fiscales y pecuniarios que aparecen en el modelo tradicional el modelo con poblacion movil presenta un nuevo efecto que distorsiona la provision de bienes publicos como en el caso del efecto pecuniario este nuevo efecto depende de si la jurisdiccion es exportadora neta o importadora neta de capital de esta manera en el caso de jurisdicciones simetricas ambos efectos desaparecen resultando en subprovision de bienes publicos en el caso donde las jurisdicciones son asimetricas ambos modelos tienen los mismos resultados cualitativos reforzando el modelo con poblacion movil los resultados de la externalidad pecuniaria englishthis paper analyzes a model of strategic tax competition with mobile capital and mobile identical consumers the results of the model are compared to the traditional strategic tax competition model with immobile population in addition to the fiscal and pecuniary externalities present in the standard model a new effect shows up in the mo bility model to affect provision of the public good as with the pecuniary externality this new effect depends on whether the jurisdictions are net exporters or net importers of capital thus in a symmetric set up the mobility effect along with the pecuniary externality disappears yielding unambiguous underprovision of the public good while in the asymmetric case both models have the same qualitative results the mobility model strengthens the effects of the pecuniary externality the above results are obtained by comparing the form of the first order conditions between the mobility and immobility cases the remaining question is whether or not the equilibrium levels of the public goods conform to the predicted tendencies this question is answered with an example the results of this exercise show that when the jurisdiction is a net exporter of capital the level of the public good is lower in the mobility case than in the immobility case however if the jurisdiction is a net importer of capital the public good level is sometimes higher and sometimes lower in the mobility case contrary to predictions

implementation in economic environments with incomplete information the use of multi stage games abstract this paper shows that in economic environments with incomplete information incentive compatibility and a preference reversal condition are sufficient for implementation in sequential equilibrium journal of economic literature classification numbers c72 d71 d82

property taxation congestion and local public goods abstract the residential property tax has been viewed as a congestion fee even if it distorts housing decisions this paper shows that the rule for a competitive jurisdiction s optimal public good supply may be written in a form in which no such role appears congestion costs enter the cost side of this rule in the same way that they enter when only a land tax is available the new rule is reconciled with an alternative rule in the literature which contains no congestion costs

taxation and the tiebout model the differential effects of head taxes taxes on land rents and property taxes on the theory of state and local public finance is the seminal paper by charles tiebout 1956 tiebout constructed a multijurisdictional model in which independent local governments offer a wide variety of expenditure and tax policies and perfectly mobile consumers reveal their preferences for local public goods through their choice of residential community he argued that under such circumstances local public service provision would be efficient the tiebout model has formed the basis of a vast number of subsequent articles in the state and local public finance literature and has also been very influential in urban and regional economics the efficiency properties of various tiebout type models of local public good provision have been examined and the role of politics in these models has been debated at length in this literature of more direct relevance to this paper however is the fact that although tiebout had little to say directly about taxation simply assuming the existence of head taxes subsequent analyses have used adaptations of this model to examine the effects of local head taxes land taxes and property taxes it is the literature on the efficiency and distributional effects of alternative local taxes that is the subject of this survey 1

optimal public good provision with limited lump sum taxation it is often argued that the use of distortionary taxation lowers the optimal provision of public goods below its optimal level in a first best economy which contains no restrictions on lump sum taxation however this issue is usually investigated using commodity tax models that contain no lump sum taxes this paper examines a many consumer economy in which the only tax instruments are commodity taxes and a poll tax subsidies are negative taxes the optimal level of public good provision in this economy typically exceeds the first best level at least for distributionally neutral public goods copyright 1991 by american economic association

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

voter heterogeneity and political corruption abstract we show that policies that eliminate corruption can depart from socially desirable policies and this inefficiency can be large enough to allow corruption to live on political competition between an honest welfare maximiser and corrupt politicians is studied in our model the corrupt politician is at a distinct disadvantage there is no asymmetric information no voter bias and voters are fully rational yet corruption cannot be eliminated when voters have heterogeneous preferences

the persistence and inefficiency of property tax finance of local public expenditures abstract i both characterize and evaluate equilibrium outcomes in multiple jurisdiction economies with property and land taxation but where direct taxation of residents is not possible the model contains perfectly mobile capital and population and competitive entrepreneurial governments that choose local taxes and expenditures to maximize after tax land rent when the cost of public goods is proportional to population the property tax emerges as the sole source of local finance even though the land tax has no deadweight loss it is shown that equilibria are not constrained efficient in general hence decentralized decision making is not consistent with the best use of the available tax instruments

efficient investments in the implementation problem abstract this paper identifies a condition for an efficient social choice rule to be fully implementable when we take into account investment efficiency to do so we extend the standard implementation problem to include endogenous ex ante and ex post investments in our problem the social planner aims to achieve efficiency in every equilibrium of a dynamic game in which agents strategically make investments before and after playing the mechanism our main theorem shows that a novel condition commitment proofness is sufficient and necessary for an efficient social choice rule to be implementable in subgame perfect equilibria the availability of ex post investments is crucial in our model there is no social choice rule that is efficient and implementable in subgame perfect equilibria without ex post investments we also show that our positive result continues to hold in the incomplete information setting

rational expectations information acquisition and competitive bidding most rational expectations market equilibrium models are not models of price formation and naive mechanisms leading to such equilibria can be severely manipulable in this paper a bidding model is developed which has the market like features that bidders act as price takers and that prices convey information higher equilibrium prices convey more favorable information about the quality of the objects being sold than do lower prices bidders can benefit from trading only if they have a transactions motive or if they have access to inside information apart from exceptional cases prices are not fully revealing a two stage model is developed in which bidders may acquire information at a cost before bidding and for which the equilibrium price is fully revealing resolving a well known paradox

the relationship between corruption and income inequality in u s states evidence from a panel cointegration and error correction model we investigate the causality between corruption and income inequality within a multivariate framework using a panel data set of all 50 u s states over the period 1980 to 2004 the heterogeneous panel cointegration test by pedroni oxf bull econ stat 61 653 670 1999 econom theory 20 597 627 2004 indicates that in the long run corruption and the unemployment rate have a positive and statistically significant impact on income inequality while a negative impact is found for real personal income per capita education and unionization rate the granger causality results associated with a panel vector error correction model indicate both short run and long run bidirectional causality between corruption and income inequality

subgame perfect implementation this paper examines the use of stage mechanisms in implementation problems and provides a partial characterization of the set of subgam e perfect implementable choice rules it is shown that in many economic environments virtually an y choice rule can be implemented to illustrate the power of this approach the paper discusses a number of models in which it is possible to implement the first best although it wouldn t have been possible to do so without using stage mechanisms the diversity of these models suggests that subgame perfect implementation may find wide application copyright 1988 by the econometric society

subgame perfect implementation under information perturbations we consider the robustness of extensive form mechanisms to deviations from common knowledge about the state of nature which we refer to as information perturbations first we show that even under arbitrarily small information perturbations the moore repullo mechanism does not yield even approximately truthful revelation and that in addition the mechanism has sequential equilibria with undesirable outcomes more generally we prove that any extensive form mechanism is fragile in the sense that if a non maskin monotonic social objective can be implemented with this mechanism then there are arbitrarily small information perturbations under which an undesirable sequential equilibrium also exists finally we argue that outside options can help improve efficiency in asymmetric information environments and that these options can be thought of as reflecting ownership of an asset

using cost observation to regulate firms the paper emphasizes the use of accounting data in regulatory or procurement contracts when the supplier 1 has superior information about the cost of the project and 2 invests in cost reduction the main result states that under risk neutrality the supplier announces an expected cost and is given an incentive contract linear in cost overruns this optimal contract moves toward a fixed price contract as the announced cost decreases an investment choice is then introduced and the use of a rate of return regulation is studied

cost reducing investment optimal procurement and implementation by auctions the authors analyze a model in which potential suppliers invest in research and development r d and then compete for a procurement contract from a buyer if the buyer is able to commit to a procurement mechanism before the investment stage the full information solution can be uniquely implemented by first price and second price sealed bid auction mechanisms when the r d technology exhibits decreasing returns to scale if the procurement mechanisms and the levels of investment are chosen simultaneously the full information solution cannot be implemented the authors discuss how the second best equilibrium contract varies with the number of suppliers copyright 1996 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

unobservable investment and the hold up problem we study a two person bargaining problem in which the buyer may invest and increase his valuation of the object before bargaining we show that if all offers are made by the seller and the time between offers is small then the buyer invests efficiently and the seller extracts all of the surplus hence bargaining with frequently repeated offers remedies the hold up problem even when the agent who makes the relation specific investment has no bargaining power and contracting is not possible we consider alternative formulations with uncertain gains from trade or two sided investment

too much investment a problem of endogenous outside options this paper shows that when agents on both sides of the market are heterogeneous varying in their costs of investment ex ante investments by firms and workers or buyers and sellers more generally may be too high when followed by stochastic matching and bargaining over quasi rents the overinvestment is caused by the fact that low cost agents by investing more can increase the value of their outside option and thus shift rent away from high cost investors numerical simulations show that overinvestment can occur given parameter values calibrated to oecd labour markets

investment and competitive matching we study markets in which agents first make investments and are then matched into potentially productive partnerships equilibrium investments and the equilibrium matching will be efficient if agents can simultaneously negotiate investments and matches but we focus on markets in which agents must first sink their investments before matching additional equilibria may arise in this sunk investment setting even though our matching market is competitive these equilibria exhibit inefficiencies that we can interpret as coordination failures all allocations satisfying a constrained efficiency property are equilibria and the converse holds if preferences satisfy a separability condition we identify sufficient conditions most notably quasiconcave utilities for the investments of matched agents to satisfy an exchange efficiency property as well as sufficient conditions most notably a single crossing property for agents to be matched positive assortatively with these conditions then forming the core of sufficient conditions for the efficiency of equilibrium allocations

entry and r d in procurement contracting abstract a model of competitive procurement and contracting is presented in this paper the key features of the model include precontract r d an endogenous number of homogeneous firms and sealed bid auction rules both diminishing and constant returns to scale drs and crs in r d expenditure technologies are considered i find that the sealed bid first price auction fpa is equivalent to the second price auction spa under drs technology the revenue equivalence theorems breaks down under crs because multiple equilibria arise in the r d stage when spa is used howerer spa yields a unique perfect equilibrium given sufficient heterogeneity among potential firms the free entry perfect equilibrium is also characterized the buyer prefers free entry through an appropriate selection of the reservation price

majority choice of tax systems in single and multi jurisdictional economies abstract we examine majority choice of tax instruments in an economy with heterogeneous households in our framework majority voting equilibrium exists despite the multidimensional policy choice set we examine single and multi jurisdictional economies we identify five competing incentives that influence choice of tax instruments equilibria generally entail a mixture of tax types with multiple jurisdictions strong reliance on head taxation in rich communities arises to deter poorer households from immigrating in spite of local incentives to use alternative tax instruments to redistribute wealth if relocation costs preclude inter community mobility the equilibrium tax system is fundamentally affected with redistribution incentives then dominating choice of instruments and tax rates limiting or eliminating head taxation fundamentally alters stratification public good provision levels and tax systems

participation costs and efficient auctions abstract suppose that risk neutral agents have independently and perhaps asymmetrically distributed private valuations for an indivisible object a mechanism assigns the object but it is costly to send messages to the coordinator in these circumstances the second price auction has an equilibrium that is classicallyex anteefficient given general opportunities to invest in information about or enhancements of own valuations in contrast the first price sealed bid auction may have no efficient equilibrium even if buyers are symmetric other properties of the first price auction are proved a semirevelation principle is established for mechanisms with participation costs journal of economic literatureclassification numbers d44 d82

on the interpretation of the modified samuelson rule for public goods in static models with heterogeneity abstract pigou argued that use of distorting taxation would increase the social cost of a public good due to the excess burden created by a distorting tax system samuelson s rule governing a pure public good must then be modified a second best rule has appeared in the literature when heterogeneity exists and an interpretation for the various effects captured by the additional terms appearing in the rule has been given we present a counterexample to the standard interpretation and provide an alternative derivation and interpretation which allows us to make a more precise distinction among the effects mentioned in the literature

inequality and institutions abstract this paper presents theory and evidence on the relationship between inequality and institutional quality we exhibit a model in which the two may dynamically reinforce each other and set to test this relationship with a broad array of institutional measures the double causality between institutional strength and a more equal distribution of income is empirically established using dynamic panel and linear feedback analysis

can high inequality developing countries escape absolute poverty do the poor face the same prospects for escaping poverty in high inequality developing countries as in low inequality countries is it possible for inequality to be so great as to stifle prospects of reducing absolute poverty even when other initial conditions and policies are favorable to growth household survey data for developing countries suggest that initial distribution does affect how much the poor share in rising average incomes higher initial inequality tends to reduce growth s impact on absolute poverty by the same token higher inequality diminishes the adverse impact on the poor of general economic contraction combining this evidence with that from recent investigations of inequality s effect on growth the author finds that if inequality is high enough countries that would have very good growth prospects at low levels of inequality may see little or no overall growth and little progress in reducing poverty or even a worsening on both counts the data the author uses suggest that such cases do occur the precision with which key parameters have been estimated makes it difficult to say with confidence how common such cases are but they appear to be in the minority what appear to be the best available estimates suggest that about one fifth of the spells between surveys he analyzed were cases in which poverty was rising yet positive growth in the mean and hence falling poverty is predicted at zero inequality inequality can be high enough to result in rising poverty despite good underlying growth prospects

relationships between corruption political orientation and income inequality evidence from latin america abstractthis research sheds light on the analysis of the impact of corruption and political orientation on income distribution in latin america although it has been theoretically demonstrated that corruption worsens the income distribution the empirical evidence has yielded ambiguous results based on biased estimates not considering a measurement error in the estimation of inequality this article fills this gap by correcting the previous measurement error bias in the fixed effects estimation additionally political orientation and its relationship with income inequality are also investigated the sample covers 18 latin american countries between 1996 and 2012 results reveal that corruption increases income inequality

a tiebout tax competition model abstract this paper analyzes a tiebout tax competition model where heterogeneity of consumer preferences is introduced into a standard tax competition framework following the modern tiebout tradition consumer sorting in the model is achieved through the activities of profit maximizing community developers once sorting is achieved the equilibrium is equivalent to that in a standard tax competition model with immobile but heterogeneous consumers a principal lesson of the analysis is that under capital taxation consumers with high public good demands are worse off than under a head tax regime in pursuit of high levels of public spending high demand communities impose high tax rates which drive away capital the analysis also establishes a number of other results
