Why Is Law Enforcement Decentralized?
Law enforcement is decentralized. It is so despite documented interjurisdictional externalities which would justify its centralization. To explain this fact, we construct a political economy model of law enforcement. Under decentralization, law enforcement in each region is in accord with the preferences of regional citizens, but interjurisdictional externalities are neglected. Under centralization, law enforcement for all regions is chosen by a legislature of regional representatives which may take externalities into account. However, the majority rule applies for decisions made by the central legislature and this implies that the allocation of enforcement resources may be skewed in favour of those who belong to the required majority. We show that the choice between centralization and decentralization depends on the technology of law enforcement and the nature of the interjurisdictional externalities.Crime, Law enforcement, Decentralization, Externalities
The Collective Action Problem: Within-Group Cooperation and Between-Group Competition in a Repeated Rent-Seeking Game
This paper analyzes the ability of group members to cooperate in rent-seeking activities in a context of between-group competition. For this purpose, we develop an infinitely repeated rent-seeking game between two groups of different size. We first investigate Nash reversion strategies to support cooperative behavior in a given group before analyzing double-edge trigger strategies which have the property
that cheating on the cooperative agreement in a given group is followed by non-cooperation in this group and cooperation in the rival group. The main conclusion is that the set of parameters for which cooperation
can be sustained within the larger group as a subgame perfect outcome is as large as that for which cooperation can be sustained in the smaller group. Hence, in contrast with Olson’s (1965) celebrated thesis but in accordance with many informal and formal observations, the larger group is as effective as the smaller group in furthering its interest

The Political Economy of (De)centralization with Complementary Public Goods
This paper provides a political economy analysis of (de)centralization when local public goods -- with spillovers effects -- can be substitutes or complements. Depending on the degree of complementarity between local public goods, median voters strategically delegate policy to either `conservative' or to `liberal' representatives under decentralized decision-making. In the first case, it accentuates the free-rider problem in public good provision, while it mitigates it in the second case. Under centralized decision-making, the process of strategic delegation results in either too low or too much public spending, with the outcome crucially depending on the sharing of the costs of local public spending relative to the size of the spillover effects. Hence, with a common financing rule, centralization is welfare improving if and only if both public good externalities and the degree of complementarity between local public goods are both relatively large
Coalition Formation and Environmental Policies in International Oligopoly Markets
This paper analyzes the problem of international environmental cooperation as a coalition
formation game. For this purpose, we develop a simple model with three countries of unequal size. Strate-
gic interactions between those countries come from the imperfect competition among producers in global
markets and from the transboundary pollution generated by the ?rms. To capture e¢ ciency gains from
coordinating policies, countries can join a coalition and sign an international environmental agreement.
The equilibrium coalition structure then depends on the country-size asymmetry and on the marginal
environmental damage. Interestingly, we show that the grand coalition is less likely to emerge as an equi-
librium outcome once two countries form a subcoalition. Furthermore, the further enlargement of the
initial subcoalition can be blocked either by the outsider or by the insiders
Cooperation in the Presence of an Advantaged Outsider
This paper analyzes how the stability of the tacit cooperation within a fringe of sev-
eral identical ?rms is affected by the presence of a more e¢ cient ?rm which does not take part
in their cooperative agreement. The model assumes that the ?rms of the fringe adopt ?stick and
carrot?strategies à la Abreu (1986, 1988) to support cooperation, while the outside ?rm plays its
one-period best response function to these strategies, regardless of the history of play. Assuming
a linear demand function and constant marginal costs, we then obtain conditions for the coopera-
tion within the fringe to be sustainable and focus on the most cooperative symmetric punishment
(MCSP) that sustains cooperation. We show that the MCSP is harsher when the number of ?rms
involved in the agreement is relatively large or when their relative cost disadvantage is relatively
small. However, both a larger number of ?rms and a larger cost disadvantage make it more di¢ cult
to sustain the cooperation
