官员规模、公共品供给与社会收入差距:权力寻租的视角

官员规模、公共品供给效率以及社会收入差距是当下社会比较关注的问题,本文试图把三个问题纳入到一个故事框架下来分析和解释。生产的进行需要官员提供资源帮扶,这需要通过雇佣下级官员来做到;当私人利益进入上级官员的收益函数时,上级官员就会促使资源的供给"人为"稀缺来设租,从而便于下级官员从生产者处收取资源租金;而资源租金的收取使得下级官员的收益高于其外部选择权收益,从而增加了下级官员职位的竞争性,又由于上级官员对下级官员职位任命权的垄断,使上级官员从下级官员处收取职位租金。分析表明,权力的设租寻租行为是造成社会收入差距出现的一个重要原因;在一个能较好限制官员关注私人收益的社会中,官员规模较小、公共品供给效率较高且因权力寻租而造成的社会收入差距较小。     

Pareto-Improving Redistribution and Pure Public Goods

In the pure public good model, the Nash equilibrium associated with one initial income distribution may Pareto dominate the equilibrium associated with another distribution of the same aggregate income. We explore this possibility and examine its implications for Pareto-improving policy intervention by undertaking a comparative static analysis of Pareto-improving tax-financed increases in pure public good provision. Under some circumstances, a government can engineer policies that raise public good provision while increasing the well-being of contributors and non-contributors. Crucial factors promoting this outcome involve a large number of non-contributors, a high marginal valuation for the public good by non-contributors and a large aggregate response of contributors to changes in their income.     

Heterogeneity and the Voluntary Provision of Public Goods

We investigate the effects of heterogeneity and incomplete information on aggregate contributions to a public good using the voluntary contribution mechanism. The non-linear laboratory environment has three-person groups as partners under varying conditions of information and communication. Bergstrom, Blum and Varian predict that increasing heterogeneity will have no effect on aggregate contributions in a no-communication environment. Ledyard conjectures a positive effect of incomplete information, a negative effect of heterogeneity, and a positive interaction of heterogeneity and incomplete information. We find that incomplete information has a small but significant negative effect. Heterogeneity has a positive effect on aggregate contributions, but its effects interact unexpectedly with communication. In a no-communication environment, heterogeneity in two dimensions (endowment and preferences) increases contributions substantially while heterogeneity in a single dimension (endowment or preferences) has little effect. In the communication environment we find the reverse. We also find a positive interaction between heterogeneity and incomplete information. Thus we reject the Bergstrom, Blume and Varian invariance result and provide mixed evidence on Ledyard's conjectures.     

Rent Seeking and Allocative Efficiency

This paper considers a rent‐seeking game (specifically, a winner‐takes‐all contest) with incomplete information. By allowing for sequential moves, a Bayesian‐Stackelberg equilibrium can be constructed. It can be shown that, at the Bayesian‐Stackelberg equilibrium, it is always possible that the allocative efficiency argument fails. That is, there are cases in which the Stackelberg follower is more efficient but loses the contest. Using a specific class of distributions, it is also shown that sometimes the corrupt official will choose the Bayesian‐Stackelberg equilibrium over the Bayesian‐Nash equilibrium in order to maximise the expected bribe revenue. That is, when designing the rules of the rent‐seeking game, the dynamic nature of competition will be taken into account.     

Heterogeneity, Coordination and the Provision of Best-Shot Public Goods

In a best-shot public good, where the provision level is determined by the highest contribution instead of the sum of all contributions, there is potential for waste and underprovision due to coordination failure. These failures are exacerbated when agents are identical because there is no focal point to guide coordination. In most real-world best-shot public-good situations, however, heterogeneity exists in the ability to contribute and the benefits received from the good. With such differences, shared expectations might emerge to improve coordination and increase efficiency. Using laboratory experiments, we find significant behavioral responses to heterogeneity that improve efficiency, but not always from increased coordination.     

The Asymptotic Voluntary Provision of the Pure Public Goods

This paper analyzes the voluntary provision of the pure public good in a sequence of finite economies. The boundedness of this provision is established under very weak conditions. The Cournot–Nash provision of the public good is bounded. In contrast, the Lindahl provision is unbounded but the proportion of private good devoted to its production may be infinitesimal. Several examples are provided to relate this paper to the literature.     

Rent Seeking with Efforts and Bids

We introduce bids in a rent-seeking contest. Players compete for a prize. Apart from exerting lobbying efforts, they also submit a bid which is payable only if they win the prize. We show that our model has a unique Nash equilibrium in pure strategies, in which each active player submits the same bid, while the sum of all efforts equals that bid. In equilibrium there is underdissipation of rent.     

On Opposition to Rent Seeking: Implications for Developing Countries

A model is developed to study the implications of the presence of rent-opposing activities for the measurement of deadweight losses and for cost–benefit analysis. The analysis provides an upper bound on the social cost of rent-seeking in the presence of potential rent-opposers. Remarks are offered on the interactions between merits and skills in the determination of success in rent-seeking, and on the pervasiness of corruption in developing economies.

国有企业外部人控制:一个寻租视角

国有企业的公共物品性导致国有企业蜕变为一个多重寻租网络.政府作为国有企业的外部控制人,借助政企不分、个人权力的无约束和责任体系弱化、多层委托与多重代理等体制性弊病的掩饰,与国有企业代理人合谋寻租,国有企业的"内部人控制"应运而生.可以说,国有企业若不存在"外部人控制","内部人控制"几乎不可能产生;国有企业若存在"外部人控制","内部人控制"便几乎一定会产生."外部人控制"产生的必要前提是国有企业泛化为公共物品,而国有企业泛化为公共物品,必须具备以下条件:包括存在可供寻租的租金、存在制度性的寻租通道、存在租金和信息的传递系统.国有企业外部人控制具有极大的危害,主要表现为降低企业家的生产性努力水平和使得企业家行为寻租化.解决问题的关键在于进行产权改革,使产权得到清晰界定并得到有效保护,同时不会出现事后寻租的现象.     

Constitutional Design for a Rent Seeking Society: The Voting Rule Choice Revisited

Buchanan and Tullock's original trade-off model of constitutional design is used to analyze how constitutional design affects post-constitutional rent seeking, and, in turn, how the anticipation of post-constitution rent seeking should lead to modification of constitutional design — specifically with respect to imposing and maintaining effective (composite) supermajority decision rules.     

Rent Seeking Behavior in Transition Countries: The Case of Romania

This paper points out, in the changing institutional setting of transition in Romania, Some relevant factors influencing economic actors to behave in a way that pushes them to devote resources to unproductive goals, rather than to embark on activities that add economic and social value. The theoretical insights offered in the literature of rent seeking are applied to the issues of transition. A mathematical model of a rent seeking economy is presented, analyzing the influence of interest groups activity on the overall income of the economy. Some examples of rent seeking behavior that severely hamper the economic efficiency are illustrated for the case of Romania. The conclusion is that, in appreciating the progress in transition, the reduction in rent seeking is an important factor to be taken into consideration.     

Collusion-Proof Samuelson Conditions for Public Goods

We analyze a public good problem when agents form a grand coalition to promote their own collective goal instead of that of society as a whole. When collusion takes place under symmetric information , the collusion-proof Samuelson rule takes a simple form that is close to an ex ante cost-benefit analysis . Then, we analyze the case where agents collude under asymmetric information . First, we describe the set of collusion-proof allocations. Second, we establish the collusion-proof Samuelson rule that highlights the role of coalitional virtual valuations . Asymmetric information within the coalition allows the principal to recover some flexibility in the design of the optimal policy. We finally discuss the nature of the inefficiency created by the agents' collusive behavior and the scope of their ex ante gain in forming a coalition.     

Threatened Species as Public Goods and Public Bads

This paper discusses Pareto efficient allocations of an environmental commodity, which is both a public good and a public bad, with an application to the Scandinavian problem of conserving wild predators that are killing semi-domesticated reindeer. The paper begins by briefly outlining this conflict. This is followed by a theoretical analysis employing a diagrammatic tool called the Kolm triangle, which is an analogue of an Edgeworth box in an economy with a public good. Bargaining, Pareto improving reallocations and the shape of the Pareto set are discussed, using a simple model, where one of the agents is involountarily contributing to a public good. The paper concludes with an analysis of income-loss compensations and incentives for illegal hunting of predators.     

寻租理论在我国的研究与发展

寻租理论是由《经济社会体制比较》杂志于1988年首先引入我国改革理论的研究的,这一理论为我国理论界分析转轨过程中腐败问题提供了新的方法和新的视点,也为我国政府适应市场经济体制的要求转变职能提供了新的思路。《经济社会体制比较》既注意刊载国外寻租理论的经典文献,又注意关注我国理论界的讨论热点,并从比较中提出了改革的对策,对推动我国改革理论的深化发挥了重要作用。20世纪90年代以后,寻租理论广泛应用于各类经济行为和现象的研究,特别是转轨经济的研究,至今这一趋势仍在继续。     

差别待遇、政策寻租与过渡性资本外逃

过渡性资本外逃是一种特殊的资本流动方式,其动机就是以外籍的身份向国内投资.我国政府对于外商投资给予的超国民待遇和税收优惠是过渡性资本外逃的主要动因.这种政策对于改革开放初期经济的现代化、市场化建设所发挥的历史性作用是毋庸置疑的,但是随着改革开放的进一步深入,政府对于外资的超国民待遇也在产生越来越大的负面效应.因此,我国政府应当对外资的超国民待遇进行重新定位,逐步取消具有明显歧视性的政策,消除内资企业的政策性寻租动机,提高内资企业的投资水平.     

Political Competition, Rent Seeking and the Choice of Environmental Policy Instruments

This paper investigates the impact of political lobbying on the choice of environmental policy instruments. It is argued that the prevalence of pollution emission standards over more efficient policy instruments may result from rent seeking behaviour. The model further predicts that when an emission standard is used to control pollution, rival political parties have an incentive to set the same standard. There is therefore a convergence of policies. Moreover, it is shown that emission taxes are more likely to be supported and proposed by political parties which represent environmental interest groups. This feature appears to accord with the observed support for environmental taxes by Green parties in Europe, Australia, New Zealand and elsewhere.     

Wealth Heterogeneity and Escape from the Poverty–Environment Trap

A mutual link between poverty and environmental degradation is examined in an overlapping generations model. Environmental quality affects labor productivity and wealth dynamics, whereas wealth distribution determines the degree to which agents rely on technology that has a large environmental load, and therefore the evolution of environmental quality. This interaction creates a “poverty–environment trap,” where a deteriorated environment lowers income, which, in turn, accelerates environmental degradation. We show that greater wealth heterogeneity is the key to escaping from the poverty–environment trap, although it can have negative effects on both the environment and output when not in the trap.     

Edgeworth and Lindahl–Foley equilibria of a General Equilibrium Model with Private Provision of Pure Public Goods

In this paper, we propose a definition of Edgeworth equilibrium for a private ownership production economy with (possibly infinitely) many private goods and a finite number of pure public goods. We show that Edgeworth equilibria exist whatever be the dimension of the private goods space and can be decentralized, in the finite and infinite dimensional cases, as Lindahl–Foley equilibria. Existence theorems for Lindahl–Foley equilibria are a by‐product of our results.     

A Case for Bundling Public Goods Contributions

We extend the model of voluntary contributions to multiple public goods by allowing for bundling of the public goods. Specifically, we study the case where agents contribute into a common pool which is then allocated toward the financing of two pure public goods. We explore the welfare implications of allowing for such bundling vis‐à‐vis a separate contributions scheme. We show that for high income inequality or for identical preferences among agents bundling leads to higher joint welfare. Interestingly, a welfare improvement can in some cases occur despite a decrease in total contributions. On the contrary, when agents are heterogenous, for low income inequality bundling can lead to lower total contributions and may decrease welfare compared to a separate contribution scheme. Our findings have implications for the design of charitable institutions and international aid agencies.
