risk aversion in contests in a contest participants spend money or effort to increase their chances of winning a prize the authors examine primarily the following question could the timid the more risk averse have a better chance of winning in contests under limited liability the answer is always positive in the absence of limited liability there is no single answer whereas when the prize is shared as a function of effort the outcome is independent of the contestants risk aversion the authors also relate their results to self protection and examine some other implications of risk aversion copyright 1995 by royal economic society

risk aversion and prudence in rent seeking games this paper considers a common n agent symmetric rent seeking game it derives conditions so that risk aversion and risk always decrease rent seeking efforts these conditions hold for any regular contest success function when risk averse rent seekers are also prudent under n 2 prudence is a necessary and sufficient condition for risk aversion to decrease rent seeking efforts compared to risk neutrality an intuition for this result is given based on a self protection model

governing private foundations using the tax law abstract this paper investigates two tax law provisions that act as governance instruments designed to regulate the behavior of private foundations it examines tax return data from a sample of private foundations to determine the effects of the minimum distribution requirement and the dual tax rate regime the minimum distribution requirement primarily affects the distribution behavior of foundations that are no longer receiving donations and are growing more slowly than the average foundation the dual tax rate regime has countervailing effects on distributions by foundations rewarding both higher levels of current distributions and lower levels of prior year distributions

rent seeking and the provision of public goods in this short paper i adopt the public choice school paradigm of modeling a government in order to compare its performance with that of the market in the standard model of the provision of public goods private provision is represented by the cournot nash equilibrium in individual contributions public provision incorporates rent seeking whereby some of the aspects of the allocation are determined indirectly by influence activities of the interested parties thus both allocation procedures yield inefficiency and the question is which procedure results in a greater amount of inefficiency private provision with its free riding incentives or public provision with its rent seeking incentives the results indicate that public provision may well be preferred to private provision of public goods thus superiority of private provision is not guaranteed even in the case of a non benevolent government copyright 1993 by royal economic society

a general model of rent seeking for public goods this paper generalizes the model of collective rent seeking over a public good expanding the rent seeker s consumption bundle to include preferences over the public good and a private good our results suggest collective rent seeking is positively related to group size although free riding exists within a group there is not a one for one tradeoff in addition rent seeking increases with wealth finally total effort expended by both groups increases if either group increases in membership size except in the case of an extremely lopsided contest the key condition underlying these results is that the marginal utility of the public good is not inversely related to the private good

aggregate comparative statics abstract in aggregative games each player s payoff depends on her own actions and an aggregate of the actions of all the players many common games in industrial organization political economy public economics and macroeconomics can be cast as aggregative games this paper provides a general and tractable framework for comparative static results in aggregative games we focus on two classes of games 1 aggregative games with strategic substitutes and 2 nice aggregative games where payoff functions are continuous and concave in own strategies we provide simple sufficient conditions under which positive shocks to individual players increase their own actions and have monotone effects on the aggregate the results are illustrated with applications to public good provision contests cournot competition and technology choices in oligopoly

risk attitudes and heterogeneity in simultaneous and sequential contests we prove existence and uniqueness of equilibrium in rent seeking contests in which players are heterogeneous in both risk preferences and production technology given identical linear production technology if the number of risk loving players is large enough the aggregate investment in equilibrium will exceed the rent and all risk neutral and risk averse players will exit the contest in simultaneous and sequential contests with two players we can identify the favorite and underdog based on both players preference parameters our theoretical results suggest that subjects in some recent contest experiments behaved as if they were risk loving

do interest groups affect us immigration policy while anecdotal evidence suggests that interest groups play a key role in shaping immigration policy there is no systematic empirical analysis of this issue in this paper we construct an industry level dataset for the united states by combining information on the number of temporary work visas with data on lobbying activity associated with immigration we find robust evidence that both pro and anti immigration interest groups play a statistically significant and economically relevant role in shaping migration policy across sectors barriers to migration are lower in sectors in which business interest groups incur larger lobbying expenditures and higher in sectors where labor unions are more important

does foreign aid distort incentives and hurt growth theory and evidence from 75 aid recipient countries foreign aid transfers can distort individual incentives and hence hurt growth by encouraging rent seeking as opposed to productive activities we construct a model of a growing small open economy that distinguishes two effects from foreign transfers i a direct positive effect as higher transfers allow the financing of infrastructure ii an indirect negative effect as higher transfers induce rent seeking competition by self interested individuals in this framework the growth impact of aid is examined jointly with the determination of rent seeking behavior we test the main predictions of the model for a cross section of 75 aid recipient countries there is evidence that aid has a direct positive effect on growth which is however significantly mitigated by the adverse indirect effects of associated rent seeking activities this is especially the case in recipient countries with relatively large public sectors

risk averse rent seeking with shared rents this paper presents a nash equilibrium model of rent seeking behavior in which risk averse players expend resources to obtain a share of a rent as for example in contests for import quota licences results are obtained relating the equilibrium level of lobbying effort by each player to the value of the rent in particular reduced individual lobbying effort is associated with higher rents contested if players are sufficiently risk averse the question of whether the value of rents is a good measure of the resource cost of rent seeking is also considered a simple approximation involving risk and risk aversion parameters is derived for the proportion of rents dissipated in long run equilibrium risk and risk aversion are seen to reduce the rent dissipation ratio below unity copyright 1987 by royal economic society

the productivity and efficiency of the australian electricity supply industry australia s electricity supply industry has been through a period of reform over the last 10 years the purpose of this paper is to analyse the changes that have occurred to the australian electricity supply industry over the past 30 years in order to evaluate to what degree these reforms have improved the productivity and efficiency performance of the industry

aid dependence and the quality of governance cross country empirical tests aid dependence can potentially undermine the quality of governance and public sector institutions by weakening accountability encouraging rent seeking and corruption fomenting conflict over control of aid funds siphoning off scarce talent from the bureaucracy and alleviating pressures to reform inefficient policies and institutions analyses of cross country data in this paper provide evidence that higher aid levels erode the quality of governance as measured by indices of bureaucratic quality corruption and the rule of law these findings support the need for donors to develop less costly and less intrusive ways of disseminating state of the art knowledge on public sector reform in developing countries

risk lovers and the rent over investment puzzle in this paper we prove existence and uniqueness of equilibrium in a rent seeking contest given a class of heterogeneous risk loving players we explore the role third order risk attitude plays in equilibrium and find that imprudence is sufficient for risk lovers to increase rent seeking investment above the risk neutral outcome moreover we show that rent can be fully dissipated in a standard tullock contest played by a large number of risk lovers

rent seeking incentives in share contests abstract this article investigates share contests in our framework we allow contestants to have more general preferences than have been used in the literature previous approaches have the unfortunate characteristic that contestants marginal rates of substitution between the rent share allocated by the contest and their effort is constant regardless of the size of the rent share this results in a conventional wisdom larger rents command more effort by providing a more general framework we show the reverse may also be true and we derive the conditions under which this is the case our approach then allows us to rationalize within a standard contest framework observations that rents might be more hotly contested when they become scarcer as has evidently been the case with the recent global contraction of public funds available for public policy

do polls create momentum in political competition abstract we explore how public opinion polls affect candidates campaign spending in political competition generally polls lead to more asymmetric behavior under a majority rule there always exists an equilibrium in which the initially more popular candidate invests more in the campaign and thereby increases her lead in expectation polls create momentum when campaigning is very effective and the race is very close a second type of equilibrium may exist the trailing candidate outspends and overtakes his opponent regardless of the type of equilibrium polls have a tendency to decrease expected total campaigning expenditures by amplifying ex ante asymmetries between candidates and thus defusing competition when candidates care also for their vote share in addition to having the majority candidates incentives crucially depend on the distribution of voters candidate preferences

risk averse rent seekers and the social cost of monopoly power there is now quite general recognition that the social cost of monopoly power encompasses the resources expended by individuals seeking to become the beneficiaries of monopoly rents however since the activity of rent seeking is generally not observable direct estimates of resources expended in quests to acquire monopoly power are usually impossible to come by 1 as a consequence the indirect approach of taking the observed value of monopoly rents as indicative of the unobserved value of the resources expended in rent seeking is quite generally adopted in approaches to evaluation of the social cost of such activity

risk aversion heterogeneity and contests we introduce a novel method of modellingcontests that avoids the complexitiesencountered by the best response function approach we analyse contests in which i there are many risk averse players ii attitudes to risk may differ acrossindividuals and iii the technology thattransforms rent seeking effort intoprobability of winning may also differacross individuals we establish that ifevery player has a constant degree ofabsolute risk aversion a uniqueequilibrium exists we also establishcomparative static results and examine howthe level of rent dissipation is affectedby the heterogeneity of attitudes towardsrisk and the precise nature of the technology

risk aversion in rent seeking and rent augmenting games the effects of risk aversion are examined for two types of expenditures in rent seeking contests a rent seeking expenditures which improve the probability that the rent is obtained and b rent augmenting expenditures which increase the size of the rent to be awarded risk aversion is shown to reduce expenditures of type b unambiguously while having an indeterminate effect on those of type a these two contrasting results are shown to derive from the very different effects rent seeking and rent augmenting expenditures have on the riskiness of a player s position

population size and civil conflict risk is there a causal link does an expansion of the population size expose nation states to a higher risk of suffering from civil conflict obtaining empirical evidence for a causal relationship is difficult due to reverse effects and omitted variable bias this article addresses causality issues by using randomly occurring drought as an instrumental variable to generate exogenous variation in population size for a panel of 37 sub saharan countries over the period 1981 2004 instrumental variable estimates yield that a 5 increase in population size raises the risk of civil conflict by around six percentage points

swords or plowshares a theory of the security of claims to property this paper develops a general equilibrium model of the allocation of resources among appropriative and productive activities the model emphasizes the distinction between offensive weapons which are the instruments of predation and fortifications which provide defense against predation the analysis of this model shows how the equilibrium security of claims to property is determined the analysis focuses on the possibility of a nonaggressive equilibrium in which no resources are allocated to offensive weapons and claims to property are fully secure we also analyze the complex relation between economic welfare and the security of claims to property we find for example that a relatively poor agent could be better off in an equilibrium with less secure claims to property

environmental pressure group strength and air pollution an empirical analysis there is an established theoretical and empirical case study literature arguing that environmental pressure groups have a real impact on pollution levels our original contribution to this literature is to provide the first systematic quantitative test of the strength of environmental non governmental organizations engos on air pollution levels we find that engo strength exerts a statistically significant impact on sulfur dioxide smoke and heavy particulates concentration levels in a cross country time series regression analysis this result holds true both for ordinary least squares and random effects estimation it is robust to controlling for the potential endogeneity of engo strength with the help of instrumental variables the effect is also substantively important strengthening engos represents an important strategy by which aid donors foundations international organizations and other stakeholders can try to achieve lower pollution levels around the world
