RENT DISSIPATION AND THE SOCIAL COST OF PRICE POLICY

This paper uses a general equilibrium-based exchange economy model to examine rent seeking for a price policy. Opposing interests spend resources to influence the government's choice of a price vector. Rents, the willingness to pay for the policy, are determined endogenously from the Nash equilibirum of a non-cooperative game. Numerical simulations explore the degree to which rents are dissipated by wasteful rent seeking. It is found that dissipation, measured as the ratio of rent-seeking costs to rents garnered, can grow without limit, and is greatest when opponents are evenly matched. Dissipation is smallest with widely disparate groups, a result that might help explain the underdissipation that seems to occur in many industries.     

Preemptive entry in differentiated product markets

Summary. Models of spatial competition are typically static, and exhibit multiple free-entry equilibria. Incumbent firms can earn rents in equilibrium because any potential entrant expects a significantly lower market share (since it must fit into a niche between incumbent firms) along with fiercer price competition. Previous research has usually concentrated on the zero-profit equilibrium, at which there is normally excessive entry, and so an entry tax would improve the allocation of resources. At the other extreme, the equilibrium with the greatest rent per firm normally entails insufficient entry, so an entry subsidy should be prescribed. A model of sequential firm entry (with an exogenous order of moves) resolves the multiplicity problem but raises a new difficulty: firms that enter earlier can expect higher spatial rents, and so firms prefer to be earlier in the entry order. This tension disappears when firms can compete for entry positions. We therefore suppose that firms can commit capital early to the market in order to lay claim to a particular location. This temporal competition dissipates spatial rents in equilibrium and justifies the sequential move structure. However, the policy implications are quite different once time is introduced. An atemporal analysis of the sequential entry process would prescribe an entry subsidy, but once proper account is taken of the entry dynamics, a tax may be preferable.

PUBLIC GOODS,RENT DISSIPATION,AND CANDIDATE COMPETITION*

The early literature on rent seeking presumed that total expenditures in the rent-seeking process would equal the value of a contested prize. Subsequent analysis has shown, however, that a number of circumstances give rise to underdissipation of the contested rent—imperfectly discriminating contests, risk-aversion, or where individuals' valuations of the prize are not identical. This paper shows how underdissipation is associated with the public-good character of contested rents. In particular, total rent dissipation is demonstrated to be less than the average stake of the individual contenders. In addition to assessing rent dissipation in contests for public-good allocations, the paper also endogenizes the value of the prize by placing the rent-seeking contest in a setting of candidate competition.     

Where are the rent seekers?

In a remarkably simple and yet one of the most original and insightful observations of 20th century economics, Gordon Tullock pointed out that there are efficiency losses when public policies and political behavior create contestable rents. Tullock also observed that social losses from contesting rents appeared smaller than might be expected, so raising the question ‘where are the rent seekers?’ Tullock proposed that political accountability and ‘free-riding’ incentives in interest groups limit social losses from rent seeking. We affirm Tullock’s explanations, which apply differently under different political institutions. We compare Tullock with Gary Becker, who focused on deadweight losses from redistribution and concluded, in contrast to Tullock, that political redistribution is efficient. The comparison with Becker highlights the significance of the recognition of Tullock’s concept of rent seeking. By excluding rent-seeking losses from the social costs of redistribution, Becker could arrive at a conclusion more favorable than Tullock to an ideology that sees merit in extensive redistribution. Tullock’s model, although more encompassing of actual social costs of redistribution, would have been less welcome in the social democratic welfare state.     

寻租理论的新发展

寻租理论把租金的范围定义在政治领域。政府拥有某些政治特权,可以创造和保护租金,从而增加人们的决策选择。出于利益最大化的考虑,人们会选择＂寻租＂方式来增加收益。正是由于＂寻租＂,遏制了市场经济发挥作用。同时,寻租活动也浪费了本应用于从事生产性活动的资源。在上述思想的指引下,寻租理论的发展出现两大分支：一是规范寻租理论,试图说明和估算寻租活动给经济带来的成本;二是实证寻租理论,试图解释社会中人为制造的租金来源。寻租被应用于很多研究领域,但是也许是由于寻租理论本身存有缺陷,或者其他原因,寻租理论在中国并没有很好地发展起来。     

Migration as an antidote to rent-seeking?

We develop a new mechanism through which skilled migration may influence economic performance in the sending country. If agents can choose between acting as rent-seekers and engaging in productive activities, and only productive skills are exportable, a positive probability of migration (to a more secure economy) reduces the relative expected returns from rent-seeking, thus decreasing the proportion of skilled workers who opt for “parasitic” activities. Such an improvement in the allocation of talent may prevail over the loss of skilled workers due to outmigration. However, we show that this result is not robust to the introduction of endogenous protection. If productive workers share their resources between accumulation of productive capital and investment in security, prospective migration may induce a weaker protection against rent-seeking, which in turn might depress average income in the source economy.

Rent, risk, and replication: Preference adaptation in winner-take-all markets

We study the evolution of an economy where agents who are heterogeneous with respect to risk attitudes can either earn a certain income or enter a risky rent-seeking contest. We assume that agents behave rationally given their preferences, but that the population distribution of preferences evolves over time in response to material payoffs. We show that, in particular, initial distributions with full support converge to stationary states where all types are still present. Although rents are perfectly dissipated in material terms at a steady state, efficiency is greater than if everybody had been risk neutral, since risk lovers specialize in rent seeking.     

Policy making and rent-dissipation: An experimental test

We present a transfer-seeking model of political economy that links the theory of Becker (1983) with Tullock-type models of politically contestable rents. In our model the size of the transfer is determined endogenously, and over-dissipation of rents is predicted even under conditions of risk-neutrality and perfect rationality. We implement an empirical test of this model by collecting behavioral data in a laboratory experiment. We confirm the existence of behavior that leads to over-dissipation of rents in games with both symmetric and asymmetric political power. To the extent that the transfer-seeking costs are social costs, our findings imply that the total costs of running government might be greatly underestimated if the value of the rent is used as a proxy for the rent-seeking cost. We also confirm the hypotheses that lowering the political power of one player can lead to smaller rent-seeking expenditures and to larger transfers Electronic Supplementary Material Supplementary material is available in the online version of this article at .

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.     

Tax competition, rent-seeking and fiscal decentralization

The present paper provides a basis for evaluating fiscal decentralization of expenditure and tax responsibilities, by encompassing the literature on tax competition and rent seeking. Both tax and rent seeking competitions are conceived of as being wasteful and self-defeating. We find that rent-seeking activities account for political distortions which may be mitigated in the process of fiscal decentralization, while tax competition results in economic distortions associated with decentralization. Welfare evaluation should be based on the balance of the political gain and the economic cost.     

Rent Seeking with Politically Contestable Rights to Tariff‐rate Import Quotas**

This paper analyzes rent seeking for agricultural import quotas and the associated waste of resources when politically contestable licenses are allocated to either or both importers and exporters. In a two‐stage simultaneous contest where firms seek rent for licenses and then bargain over the import/export price, it is shown that (1) rents are not dissipated completely because of uncertainty in allocation of “rights,” (2) the dissipation ratio increases if the country with a more competitive contest increases the probability of establishing licenses, (3) rent seeking may cause the market structure to change, (4) less rent is dissipated in the case of pre‐existing market power, and (5) allocation of multiple licenses decreases rent‐seeking outlays.     

WINNER-HELP-LOSER GROUP FORMATION IN RENT-SEEKING CONTESTS*

We define a winner-help-loser group in a rent-seeking contest as follows: (a) the member players compete noncooperatively to win the rent, and (b) if a member player wins the rent, he helps the losing member players according to the previously written agreement. We demonstrate that one and only one winner-help-loser group is formed voluntarily. One important consequence of such group formation is that rent dissipation is small relative to individual rent seeking. Therefore, such group formation decreases the social cost associated with rent seeking and thus decreases the economic inefficiency of rent seeking.     

Regulatory Entry Barriers,Rent Shifting and the Home Market Effect

This paper introduces regulatory entry barriers in a model of the home market effect. The entry barriers generate local rents that have unexpected but significant implications. First, the home market effect is magnified. Second, when countries are sufficiently unequal in size and rents are sufficiently large, symmetric reductions in trade costs reduce welfare in the small country. Third, entry barriers increase the large country's market size and, surprisingly, can increase its welfare. Fourth, a unilateral increase in trade protection shifts foreign rents to the home country. This rent‐shifting effect amplifies the standard production relocation motive for trade policy intervention.     

High profit equilibria in directed search models

We consider a model of directed search where the sellers are allowed to post mechanisms with entry fees. Regardless of the number of buyers and sellers, the sellers are able to extract all the surplus of the buyers by introducing entry fees and making price schedules positively sloped in the number of buyers arriving to their shops. This is in contrast to results that are achieved for large markets under the assumption that sellers cannot influence the utility of any particular buyer (market utility assumption), in which case buyers obtain strictly positive rents. If there is a bound on the prices or on the entry fees that can be charged, then the equilibrium with full rent extraction does not exist any more, and the market utility assumption is restored for large markets.     

A Model of Inequality and Interest Group Politics

In this paper we examine inequality of process and inequality of outcomes in interest group politics. The model has interest groups that compete for rents in a non-cooperative game. It allows for a self-interested rent-setting political decision-maker, and democratic or popular pressure as a check on that self-interest. We consider differences in the effectiveness and pre-commitment abilities of interest groups. We show that: (i) the costs of influence activities may be highest when groups are relatively equal in their effectiveness; (ii) if social welfare incorporates enough concern for equity of outcomes, that ranking is reversed; (iii) depending on voter responsiveness to rent-setting, the political decision-maker may set rents to be higher or lower, when increases in inequality of effectiveness lower the unit costs of rent-seeking.     

Structural holes in social networks

We consider a setting where every pair of players that undertake a transaction (e.g. exchange goods or information) creates a unit surplus. A transaction can take place only if the players involved have a connection. If the connection is direct the two players split the surplus equally, while if it is indirect then intermediate players also get an equal share of the surplus. Thus, individuals form links with others to create surplus, to gain intermediation rents, and to circumvent others who are trying to become intermediary.Our analysis clarifies the interplay between these forces in the process of strategic network formation. First, we show that, in the absence of capacity constraints on links, it leads to the emergence of a star network where a single agent acts as an intermediary for all transactions and enjoys significantly higher payoffs. Second, we study the implications of capacity constraints in the ability of agents to form links. In this case, distances between players must be long, which induces players who are “far off” to connect in order to avoid paying large intermediation rents. A cycle network then emerges, payoffs being equal across all players.     

Duration of Rent Extraction and the Entry Mode Decision of Multinational Enterprises

The prior literature is ambiguous about the effects of stronger intellectual property rights (IPR) on the choice of a multinational firm's mode of entry into foreign markets. However, available indexes of IPR protection exist only at the country level and do not identify interindustry variation in the ability to extract rents through exclusive rights and other factors. The authors introduce this dimension and compute a parameter that reflects the relative length of time that positive profits may be earned in various industries. Estimation results find that strengthening IPR would reduce exporting in all industries in the sample. However, it would raise (reduce) foreign direct investment, relative to licensing, in industries with shorter (longer) rent‐extraction times.     

Development and inefficient regulation under the threat of revolution

This paper considers a model of strategic interaction between a rent-seeking elite ruling class and a disenfranchised working class, whose ability to revolt constrains the elite’s choice of economic institutions. The disenfranchised are imperfectly informed about the economy’s productive capacity, an asymmetry which the elite may exploit to implement distortionary economic regulations to create rent in excess of that which can be generated in a relatively more efficient manner. Our main result is that, the manner in which the elite will extract rent depends on the economy’s level of development. We demonstrate that below a threshold development level the elite choose relatively inefficient regulation and above the threshold development level the elite choose relatively efficient taxation.     

Rent seeking and the economics of corruption

The paper studies the influence of Tullock (West Econ J 5:224–232, 1967) and the rent-seeking literature more generally on the study of corruption. The theoretical corruption literature with its emphasis on principal-agent relationships within government and rent creation by corruption politicians has largely, but not entirely, overlooked that contestable rents encourage unproductive use of real resources in seeking these rents. As a consequence, the literature underestimates the value of corruption control and the cost of corruption itself.
