On the limits to rent-seeking waste

The general equilibrium framework developed in this paper for analyzing the limits to rent-seeking waste goes beyond the existing literature by incorporating tax-financed, public subsidies and rent-protecting activities into a rent-seeking environment. We show that the limits to rent-seeking waste depend on the extent to which government subsidizes rent seekers and rent defenders through tax-financed grants, contracts and favors. As observed by Tullock (1967), the diversion of resources toward efforts to acquire a monopoly rent causes a social waste in addition to the excess burden of monopoly pricing measured by the Harberger triangle. In the absence of government subsidies to rent-seeking and under competitive conditions, this additional waste cannot exceed the maximum monopoly rent attainable. However, if government subsidizes expenditures on rent-seeking, then the additional waste can exceed the Tullock rectangle of monopoly rent and, in the limit, equal the economy's maximum potential social surplus.Rent avoidance expenditures reduce the rent to be captured and thus discourage rent-seeking. If rent avoidance is a relatively efficient mechanism for transferring consumer surplus to rent granters, then rent-seeking expenditures are displaced by less wasteful expenditures on rent defending. As a result, under competitive conditions, unsubsidized demand for private rent protection may be socially efficient. Nonetheless, the upper limit to rent-seeking waste depends on constitutionally determined maximum rates of public subsidies to rent-seeking and rent-avoidance activities.     

The design of rent-seeking competitions

In the standard Tullock model of rent-seeking as a noncooperative game, aggregate expenditures by seekers can equal, exceed, or fall short of total rents depending on what is assumed about the number of seekers and the marginal return to a seeker's investment. If the supply of an input into the rent-seeking process is controlled by a politician who receives payment from seekers for it, the indeterminacy of the process becomes a less serious problem. He supplies it and designs the rent-seeking game to maximize his wealth. The author derives expressions for the number of seekers and the marginal return parameter which maximize the politician's wealth in one-input and two-input rent-seeking processes.     

Spontaneous order and the common law: Gordon Tullock’s critique

Gordon Tullock critiques two specific aspects of the common law system: the adversary system of dispute resolution and the common law process of rulemaking, contrasting them with the inquisitorial system and the civil law systems respectively. Tullock’s general critique is straightforward: litigation under the common law system is plagued by the same rent-seeking and rent-dissipation dynamics that Tullock famously ascribed to the process of legislative rent-seeking. The article concludes that Tullock’s critique of the adversary system appears to be stronger on both theoretical and empirical grounds than his critique of the common law system of rulemaking.     

X-efficiency,rent-seeking and social costs

This paper investigates shifts in cost functions of monopoly and regulated firms operating under conditions of X-inefficiency and rent-seeking behavior. We show that X-inefficiency and rent seeking have significantly different implications for economic welfare. Distinctions are drawn between pecuniary and real X-inefficiency and between sunk and continuing rent-seeking costs. In general, for a given cost shift rent-seeking behavior implies larger social costs than does X-inefficiency theory. However, cost shifts caused by either X-inefficiency or rent seeking are observationally equivalent. This implies empirically measured cost shifts cannot unambiguously be attributed to either cause.     

Imperfect rent dissipation with unionized labor

Traditional rent-seeking theory focused only on socially wasteful expenditures by firms competing for restrictive regulations. More recently, rent-defending expenditures by consumers have also been taken into account. This paper extends the analysis by adding rent-sharing expenditures by organized labor. The paper merges the Tullock lottery model and the monopoly union model and considers both a costless and a costly wage bargaining mechanism. The participation of consumers and workers in the distributional contest is shown to reduce, rather than increase, the social cost of restrictive regulations. The participation of consumers and workers also raises the probability of deregulation.     

Endogenous sharing rules in collective-group rent-seeking

This paper examines the possibility of endogenous determination of intra-group sharing rules in a collective-group rent-seeking game. Collective-group rent-seeking is considered as a two-stage Nash-Cournot game in which sharing rules are determined prior to individual decision on voluntary contribution. The solution is subgame perfect and is obtained by backward induction. In competition between two groups of the same size, the Nash equilibrium sharing rule of each group is to distribute rent to each according to relative effort. Total rent-seeking outlays in this case are equal to those obtained by Tullock (1980). When more than two groups compete for a rent, the sharing rule based on relative effort is again likely to be the Nash equilibrium strategy of each group. The amount of total rent-seeking outlays is also equal to that in Tullock (1980). In a nutshell, the rent is substantially dissipated if sharing rules are endogenously determined.     

Efficient Rent-Seeking in Experiment

In a series of experiments we show that people learn to playthe efficient outcome in an open-ended rent-seeking game. Thisresult persists despite quite different experimentenvironments and designs, like different propensities ofcompetition, group sizes etc., and is interpretable as aresolution of the so-called Tullock paradox which states thatreal-world rent-seeking expenditures are much lower than whatthe standard rent-seeking model predicts.     

Improper Selection of High-Cost Producers in the Rent-Seeking Contest

The resources two rival businesses spend to raise their own chanceof getting a unique monopoly license are a cost of rent-seeking.When those businesses differ in the costs of producing themonopoly good there is an additional cost of rent-seeking that hasnot been sufficiently studied in the literature. If the high cost producer winsthe license, the difference between his cost and the costs of hismore efficient rival is a social loss from improper selection ofproducers by the political process. The loss becomes more severewhen the ability to lobby of the inefficient producer outstripsthat of the efficient producer. This may help to explain whyspecialized lobbying evolved. Specialized lobbying reduces thesocial cost from improper selection of firms by allowing efficientproducers to hire expert rent-seekers and so to raise theirchances of gaining monopoly concessions.     

Do too many cooks always spoil the stew? An experimental analysis of rent-seeking and the role of a strategic buyer

Laboratory methods are used to evaluate the effects of institutional arrangements and rent-defending activity on rent-seeking auction outcomes. In part, Nash equilibrium predictions are a useful behavioral guide: As predicted, more rents are dissipated in perfectly-discriminating auctions, where the high-bidder wins, than in lotteries, where relative bids determine the chance of winning. Also as predicted, the introduction of a rent-defending buyer reduces social costs. Nevertheless, the social costs of rent-seeking consistently exceed predicted levels. Moreover, individual bidding, especially by buyers, deviates markedly from Nash predictions.     

Gordon Tullock and experimental economics

Gordon Tullock’s research has substantially influenced the development of economic science in general and experimental economics in particular. We present the first comprehensive survey of this significant achievement. We show how Tullock’s research in bioeconomics influenced later developments in neuroeconomics and how his pioneering work on rent-seeking generated a literature of laboratory tests of his hypothesis. We also describe Tullock’s own experiments and draw attention to his early insights on trust games.     

Tollison costs and technological innovation: The case of environmental regulation

This paper departs from the Tullock cost paradigm that views competition for monopoly privilege as a welfare-inimical process that wastefully dissipates preexisting producers' surplus and, occasionally, leads to inefficient increases in costs and counterproductive uses of scarce resources. The potential availability of rent-seeking may bring about the elimination of inefficient regulatory regimes that retard or prevent the introduction of cost-reducing innovations. Air quality management is but one area in which innovation rent-seeking holds promise for concrete welfare gains. Researchers may wish to focus on institutional mechanisms designed to overcome the transactions costs and free rider disincentives to the formation of a coalition to seek innovation rents. An example of such a mechanism might be a joint venture that requires all venture members to engage in lobbying and to contribute to collective research efforts. These unaddressed questions await future research.The authors are grateful for the insightful comments of Gordon Tullock, Robert D. Tollison, Michael T. Marlow and J.R. Clark.

The constitutional political economy of Gordon Tullock

This paper surveys Gordon Tullock’s contributions to constitutional political economy. His first major contribution was his joint project with James Buchanan on liberal constitutional design. The explicitly constitutional analysis of The Calculus was followed by a series of papers and books that focused on the use of resources in conflict, including Tullock’s contributions to the anarchy and rent-seeking literatures. Tullock also pioneered the rational choice-based analysis of dictatorships and the relative merits of alternative legal systems, topics that has been neglected until fairly recently by most scholars working in the CPE tradition.     

Political instability in Africa: A rent-seeking approach

The foregoing analysis developed the paradigm of self-interest motivated revolutionary activities. In effect, the construct presented differs from the by-product theory developed by Tullock only in its specific modeling of government-created rents as the engine which drives the violent political behavior. The empirical test of the positive relationship between rent creation by the government and the amount of destabilizing political activity yields strong support for the structuring of politically destabilizing activities as rent-seeking in nature. It is the authors' hope that further empirical investigation and a more general and rigorous modeling of revolution as a rent-seeking activity will become an important part of the literature in public choice.Finally, some policy implications should be discussed. The policy emphasis for the governments of Africa countries should be on opening the economy to competition. Instituting programs to make the economic system more accessible to all segments of society would result in reduced opportunities for rent-seeking. Reducing rent-seeking should result in increased political stability. A reduction in government market intervention would also reduce the costs of government regulations on individual entrepreneurs inducing them to increase their participation in economically productive activities. Taken together the result would be increased political stability and higher rates of economic growth.     

Rent-seeking in the classroom and textbooks: Where are we after 50 years?

In this paper, we provide an overview of the influence of Tullock’s work on rent-seeking in the area of economics education. After summarizing the basic rent-seeking model in both a domestic and international context, we conduct an analysis of undergraduate and graduate textbooks in public economics. We find a majority of undergraduate texts cover rent-seeking in depth, but two texts provide zero coverage. No graduate textbook surveyed mentions rent-seeking. We conclude by summarizing the economic education literature on rent-seeking, which can be divided into either classroom experiments or popular culture examples.

     

Litigation and legal evolution: does procedure matter?

Gordon Tullock’s critique of the common law runs against much of the conventional wisdom in the law and economics literature. In this paper we revisit one of the most controversial aspects of Tullock’s critique. By applying Tullock’s own model of rent-seeking to litigation, we study the effect of alternative procedural rules on civil litigation. Our results provide support for Tullock’s controversial critique of the common law, revealing an evolutionary bias in the production of legal rules by courts. We extend the standard litigation model to study the effects of alternative procedural systems on the evolution of the common law.     

Rents, dissipation and lost treasures: Rethinking Tullock's paradox

In this paper we revisit Tullock's paradox (Tullock, 1980) and consider a rent-seeking game in which parties face increasing returns to effort. We allow parties to randomize their strategies and give them an exit option. Given the mixed participation strategies of the parties, valuable rents may occasionally remain unexploited. We consider such a lost-treasure effect as an additional cost of rent seeking and examine how the expected value of such a lost rent varies with changes in the parameters of the problem.     

The economic theory of rent seeking

Tullock’s concept of rent seeking was the first statement of a quantitative principle about the social costs of such activities as lobbying and favor seeking. As such, this part of Tullock’s legacy to modern economics is one of his most important contributions.     

Rent-seeking and X-inefficiency

This paper discusses the social cost of monopoly with special attention given to the geometric representation of that social cost, notably rent-seeking and X-inefficiency. The possibility of an overlap between these two measures is examined. In particular the paper addresses a problem of measure identification which highlights the need to reconsider the normative microfoundations of rent-seeking.     

An analysis of rent-seeking games with relative-payoff maximizers

In this paper, we introduce relative-payoff maximizing firms into the Tullock model of rent-seeking. These firms try to realize higher (expected) payoff than other firms. As a consequence of this, the outcome of the model changes: Firms, on average, will invest more in the rent-seeking process, the rate of dissipation of the rent becomes independent of the number of rent-seekers, dissipation becomes complete in cases where underdissipation prevails in the original model.     

Rent-seeking in natural resource quota allocations

This paper examines the incentives for rent-seeking in the allocation of natural resource quotas to competing user groups by political bodies. The political body has discretion in making the allocation, and competing user groups rent-seek to influence the allocation. We investigate ways in which the governmental body can affect the behavior of the players by setting the ground rules for the competition. A political body can affect an allocatively (Pareto) efficient outcome by choosing an appropriate default (pre rent-seeking) policy. Surprisingly, an allocatively efficient default policy is unlikely to minimize social costs. However, winner-take-all default policies are likely to maximize, not minimize, rent-seeking. A competitive post-allocation market reduces rent-seeking, but is not, either itself or in combination with an efficient default policy, capable of minimizing social costs. However, forcing winners in political redistributions to fully compensate losers both lowers the rent-seeking levels relative to a potential compensation criterion and, when used together with an efficient default policy, is capable of obtaining the first-best solution of an allocatively efficient allocation with zero rent-seeking.
