Dissertation abstract: The experimental analysis of the political economics of fisheries governance

This dissertation focuses on the political economy of fisheries governance. The study develops a formal model of fisheries governance by combining the features of the common pool fishery and the political institution of lobbying; designs a laboratory fishery governance institution and conducts economic experiments to test the hypotheses derived from the formal model. Specifically, the study analyzes how fishing firms invest in efforts to influence fishery regulation and management through voluntary contribution lobbying. The study also analyses and compares contribution and effort behavior in the lobbying and the CPR using data from economic experiments. The results indicate that lobbying to change suboptimal fishery regulations was significantly below the subgame perfect equilibrium prediction and contributions to raise the cap were significantly different than contributions to lower the cap toward the social optimum. Study results show that subjects successfully lobbied to raise inefficiently low fishing quotas, but were unable to lobby to reduce inefficiently high fishing quotas. Detailed analysis of subjects’ contribution and effort behavior suggest that despite the interesting benefit-cost duality between pure public goods and CPRs, the pattern of cooperative behavior in these two social dilemma situations was different and the level of cooperation in the voluntary contribution lobbying experiment was lower than those reported in other public goods experiments. To provide external validity to these experimental findings, the study further analyzes and compares lobbying expenditures in the fishery sector with those in other natural resource industries using field data from the United States. A comparison of actual lobbying expenditures as percentage of valued added shows that lobbying effort in the U.S fishery sector is not significantly different than those in other natural resource industries such as mining and electric utility industries, but the pattern of lobbying is different. Whereas fishing firms lobby through associations or pressure groups, firms in other natural resource industries lobby unilaterally. This observation suggests that differences in industrial structure and incentives influence the pattern of lobbying and the lobbying behavior of firms across industries. The theoretical predictions derived from the formal model of fisheries governance are consistent with our experimental findings and with the field data on lobbying in the US fisheries sector. These findings suggest that heterogeneity drives rent-seeking activities in the US fisheries sector and that fishing firms attempt to circumvent political collective action problems by forming and lobbying through associations of stakeholders with relatively homogenous policy preferences.

Pure strategy and no-externalities with multiple agents

Summary. This note considers two properties of common agency models - pure strategy equilibria with simple competition are robust and equilibria in mechanisms can be reproduced as equilibria with simple competition provided an appropriate no-externalities assumption holds. This note provides counter examples to both these theorems when there are multiple agents.Received: 30 April 2002, Revised: 7 January 2003, JEL Classification Numbers: D82.     

A restriction on lobbyist donations

This paper studies the consequences of a fine for violating a ceiling on permissible donations in a competition for a political prize. Increasing the fine can increase or decrease the amount of expected donations in equilibrium.     

Experimental evidence on coverage choices and contract prices in the market for corporate insurance

In this paper, we present experimental evidence on the effect adverse selection has on coverage choices and pricing in corporate insurance markets. Two sets of experimental data, each generated by experiments utilizing a specific parameterization of a corporate insurance decision, are presented to gauge these effects. In the first, subject behavior conforms to a unique equilibrium in which high risk firms choose higher coverage and contracts are priced accordingly. Insurers act competitively and convergence to equilibrium behavior is marked. In the second set, there is little evidence that subject behavior is consistent with either of the two equilibrium outcomes supported by the experimental setting—pooling by fully insuring losses and pooling by self insuring.

Endogenous residual claimancy by vertical hierarchies

In this note we study a model of vertical hierarchies where the allocation of residual claimancy is endogenous and is determined jointly with production and contractual decisions. We show that the (equilibrium) allocation of residual claimancy may be affected by production externalities across hierarchies in a non-trivial manner. Specifically, although revenue-sharing contracts foster agents’ (non-contractible) surplus enhancing effort, we show that principals dealing with exclusive and privately informed agents might still prefer to retain a share of the surplus from production when dealing with inefficient (high-cost) types. This is because reducing the surplus share of those types reduces the information rent given up to efficient (low-cost) types by means of a ‘generalized competing contracts’ effect.

Simple measures of endogenous free-riding in protectionist lobbies

Even though there is a well-known empirical and theoretical link between lobby and the free-rider problem, the existing literature only attributes its findings to the free-rider rather than the measurement of its extent. We develop broader theoretical micro-foundations for measuring free-riding and investigate the determinants of tariff rates from the perspective of corporate lobbying and free-riding. Our estimation result shows that the degree of free-riding not only varies across industries but is particularly high in larger industries indicating the underutilization of lobbying. The tariff rates under monopoly are about 8 times higher than under perfect competition in most industries suggesting that stakeholders should maintain higher industry protection levels through lobbying.     

Collusion and group lending with adverse selection

In an environment with correlated returns, this paper characterizes optimal lending contracts when the bank faces adverse selection and borrowers have limited liability. Group lending contracts are shown to be dominated by revelation mechanisms which do not use the ex post observability of the partners' performances. However, when collusion between borrowers under complete information is allowed, group lending contracts are optimal in the class of simple revelation mechanisms (which elicit only the borrower's own private information) and remain useful with extended revelation mechanisms.     

Endogenous capital market imperfections, human capital, and intergenerational mobility

In this paper, capital market imperfections are endogenized considering an adverse selection problem between banks and borrowers. We develop a growth model with linear OLG wealth dynamics, where agents are heterogeneous in terms of observable wealth and ability, which is private information. We show that banks react to this informational asymmetry by granting higher loans to talented borrowers. This, in turn, helps poor and talented agents to become educated and catch up with the rich agents. Furthermore, the credit market friction leads to greater human capital accumulation.     

Insurance contracts with imprecise probabilities and adverse selection

Summary. This article deals with optimal insurance contracts in the framework of imprecise probabilities and adverse selection. Agents differ not only in the objective risk they face but also in the perception of risk. In monopoly, a range of configurations that VNM preferences preclude appears: a pooling contract may be optimal, incomplete coverage may be offered to high risks, low risks may be better covered.Received: 1 November 2001, Revised: 15 April 2003, JEL Classification Numbers: D81, D82, G22.Useful suggestions by Emmanuelle Auriol, Bernard Bensaïd, Michéle Cohen, Isaac Meilijson and the anonymous referee are acknowledged.
