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.     

Risk aversion and rent-seeking: An extension and some experimental evidence

Theoretical investigations indicate that the risk attitudes of individuals will effect the amount of rent that can be assumed to be dissipated by rent-seeking activities. Following this line of investigation we extend Hillman and Katz's work to a small numbers case and demonstrate that the degree to which a monopoly rent is dissipated is dependent upon the structure of the risk attitudes of two risk averse individuals.Our earlier laboratory results were evaluated with respect to the risk neutral Cournot-Nash predictions. However, given the uncertainty present in the rent-seeking experiment, our ability to reject these risk neutral predictions may not be, in fact, a failure for the model but a result of risk aversion. In laboratory experiments in which we control for the relative risk attitudes of individual agents, we show that risk aversion matters. The relative risk aversion of individuals affects the level of rent-seeking activity and the extent to which rents are dissipated. In our experiments, the relatively less risk averse individuals dissipated relatively more rent.     

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.     

On the incentives to establish and play political rent-seeking games

Legislators will enact programs that encourage rent-seeking only if they can thereby increase their chances of winning election, or of receiving contributions themselves. The paper shows rent-seeking to be electorally robust — both voters and contributors will often avoid a candidate who proposes to eliminate rent-seeking. Important exceptions arise, however, if contributions are more likely to help challengers than incumbents, and if legislators prefer that some firm rather than another receive governmental contracts.I thank an anonymous referee, members of the Public Choice Study Group at UC Irvine, and Stergios Skaperdas for their comments.     

Privately informed seekers of an uncertain rent

Two departures from antecedent rent-seeking models are invoked: a rent of unknown size is sought, and rent seekers obtain private imperfect estimates of this size. A symmetric equilibrium for a fixed number of rent seekers is characterized, and shown to underdissipate the rent. Then a model of the decision to obtain private information and participate in the rent-seeking contest is built. The symmetric equilibrium participation probability equates expected profit to participation costs. A simple formula for underdissipation results: dissipation is incomplete precisely by the expected aggregate participation costs. If an award mechanism can attain a lower level of dissipation for a fixed number of seekers, then it will raise the endogenous probability of participation, and as a result will dissipate less rent in the equilibrium with an endogenous number of seekers.     

Rent-seeking and pesticide legislation

This paper provides a test of the Appelbaum and Katz (1987) rent-seeking model, in which rents are endogenous. The Appelbaum-Katz model is theoretically modified to correspond to our empirical application, in which rent-seeking and rent-avoiding coalitions are attempting to influence legislators' votes on pesticide regulations. Probit estimations are used to analyze the legislators' votes on two bills to amend pesticide legislation (a proxy for rent). Empirical results generally support the rent-seeking determinants identified in the model. Tobit estimation is used to investigate campaign contributions by the coalitions to the legislators. These contributions are a proxy for rent-seeking activities. Again, the model is supported.     

How organizational structure can reduce rent-seeking

In multi-tiered organizations, individuals can engage in unproductive rent-seeking activities both within and between the divisions of the organization. Nevertheless, a multi-tiered organizational structure can induce efficiency gains by decreasing rent-seeking. We present a model of production and simultaneous internal and external rent-seeking, assuming a logistic contest success function. In equilibrium, there is generically either internal or external rent-seeking, but not both. A multi-tiered organization leads to less rent-seeking and higher welfare, even though the production technology gives no reason for any specific organizational structure. Our findings constitute a new efficiency rationale for multi-tiered organizations.     

The convergence of fiscal regimes and the decline of the Tiebout effect

A measure of waste from the competitive rent-seeking activity of special interest groups in federal, state and local budgets was calculated over the period 1900–88. This period in U.S. fiscal history is characterized by constitutional changes that have made for more transparency in governmental fiscal activities and for greater diffusion of taxes. The XVI Amendment to the Constitution created the progressive individual income tax (the corporate income tax was judged to be an excise tax in 1909 and passed the test of constitutionality). High marginal tax rates are a justification for a high average level of taxation. The Full Employment Act of 1946 insitutionalized government deficits as a means of meeting a political objective. As a result, opportunities for rent-seeking through budgetary reallocations rose in the United States. In the first two decades of the 20th century, waste at all levels of government represented about 10 percent of incremental national output. Today, waste is three times that amount.The transparency and diffusion of taxes are highest at the federal level and least at the local level. Rent-seeking through budgetary reallocation has followed the public purse. One explanation for the observed centralization of government in the 20th century may be that opportunities to concentrate benefits and diffuse taxes are highest at the federal level.     

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.     

Rent-seeking,political influence and inequality: A simple analytical example

A simple model allowing an analysis of the interaction between economic policy decisions and rent-seeking by private agents competing for political influence, is developed. Rent-seeking may be of the directly unproductive type, requiring resources that are withdrawn from productive activities, or it may manifest itself as income transfers (corruption) to political decisionmakers. In the political-economic equilibrium of the model the extent of rent-seeking, economic policy decisions, income inequality, etc. are endogenously determined.     

Some Implications of Corporate Taxation for Rent-Seeking Activity

In this paper we show that corporate taxes are likely to have considerable implications for rent-seeking activity. We find that corporate taxation tends to significantly reduce rent-seeking, and that it favors rent-seeking by established firms and discriminates against new and zero profit firms. Indeed, we show that corporate tax regulations may completely block rent-seeking by new corporations, and that rent-seeking competitions may be characterized by an equilibrium that features a small number of profitable and well established firms. Tax regulations may therefore impart an oligopolistic tendency to rent-seeking markets. Moreover, our results may have significant implications for the effects of corporate taxes on patent races, tournaments, and other first-past-the-post competitions.     

Book reviews

This paper considers the effect of rent-seeking on the welfare implications of price discrimination by a monopolist. It is shown that even when rent-seeking fully dissipates monopoly profits, it is possible for price discrimination to raise social welfare. Thus, the recognition that monopoly profits attract resource using, socially wasteful activities, does not necessarily negate price discrimination as a defence of monopoly.     

The measurability of budget related rent-seeking

It has been suggested that the extent of rent-seeking expenditures arising from attempts to influence budget allocations should be estimated by the absolute magnitude of the observed changes in allocation. Instead, we argue that it is the extent of theex ante prospective changes that determine the level of rent-seeking, and that in the presence of countervailing activity these may be quite unrelated to the ex post observed values. We further argue that the traditional rent-seeking model of competition for a pre-specified rent is inappropriate in this context.     

Illegal markets and the social costs of rent-seeking

This paper argues that making goods or services illegal results in an increase in the social costs associated with rent-seeking. The increased social cost is in the form of negative externalities that result from market participants use of coercion and violence in attempts to control trade in the illegal good. Consequently, the social costs of rent-seeking will exceed the value of resources dissipated in rent-seeking competition. And, where the external costs exceed the undissipated portion of the Tullock cost, the social cost of rent-seeking is greater than the sum of Tullock and Harberger costs.     

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.

     

Rent-seeking behaviour of retaliating agents

This paper has examined a rent-seeking game where the players take a more sophisticated approach to evaluating the potential strategies and counter-strategies of their rivals than in the standard Nash case. We have derived the conditions for the existence of symmetric and nonsymmetric equilibria for the game and derived the properties of these equilibria. Three results merit repeating. First, we find that rent dissipation will not, in general, be complete. Second, and in contrast to much of the traditional literature, we find that the socially optimal result of zero rent-seeking is sometimes a feasible equilibrium outcome for our game. Finally, there exist rent-seeking configurations in which the best play of one of the rivals is to withdraw from the game or, alternatively stated, where it is not optimal for a rival to contest the rent by entering the game. In these nonsymmetric cases it would appear that Tullock's conjecture about the value of preemptive moves remains valid. This is true even when the strategies and counter-strategies available to the players are much more complex than in the traditional Nash approach.As a final point we raise the issue of whether or not it is reasonable to suppose that the players in rent-seeking games will take their strategy and counter-strategy sets to be as large as we have assumed in this paper. Players may well make their moves and counter-moves based upon rules of thumb or other considerations that effectively bound the strategy sets of the players. As well, it may be useful to consider games where players, upon entering the game, commit themselves to a given level of expenditures. Many of these issues are considered in a related paper by the authors.     

Rent-seeking and the two-track price system in China

A simple general equilibrium model is specified to analyse the impact on the Chinese economy of the introduction of a two-track price system on to a centrally-planned economy. It is shown that national income will rise as a result together with a fall in the costs associated with rent-seeking. Some estimates of welfare gains and costs of rent-seeking are provided for seven commodities within a partial equilibrium framework. They are shown to be dependent on the price elasticities of demand and supply. The latter determine the ratio of plan to market prices and the share of plan in total output.     

Clientelism,corruption, and the allocation of resources

Corruption has been shown to have more serious effects upon allocation than simply drawing resources into rent-seeking activities. If politicians anticipate gains from corruption in the policy making process, sub-optimal policies will be the result. Typical examples include excessive nationalization of industry, excessive regulation of the private sector through practices such as licensing and quotas with a view to extract the rent created by these measures. In addition, further misallocation will result at the execution state. It has been shown that the revisionists were wrong in assuming that licenses and contracts will be allocated to the most efficient producers, that rent will be eliminated in government employment, and that corruption increases the efficiency of the bureaucracy. Moreover, differential access to government services leads to additional allocative losses.     

The number of rent-seekers and aggregate rent-seeking expenditures: An unpleasant result

I examine a rent-seeking contest in which the winner gets a minimum rent but also gets an additional rent which is an increasing function of his lobbying expenditure. I give real-world examples of such rent-seeking competitions. Contrary to the standard result in the rent-seeking literature, I obtain the perverse result that aggregate rent-seeking expenditures may be inversely related to the number of rent-seekers. However, I note that even if this result holds, the cost of administering rent-seeking competitions may imply that society is better off with fewer contenders than with an infinitely large number of contenders, although the optimal number may not be the smallest number.     

Rent-seeking with scarce talent: A model of preemptive hiring

In a standard rent-seeking contest, players optimally employ resources in an attempt to obtain the rent. Typically, it is assumed that these resources may be hired at any desired level at some exogenous per-unit cost. In practice, these resources often consist of scarce, talented individuals. We model a rent-seeking contest with scarce talent and find that talent scarcity leads to preemptive hiring by the player receiving the larger rent. This player hires all available talent and wins the contest with probability 1. This is true even when the difference in rents is small.
