In this general equilibrium model, justice and police institutions are treated as a mechanism that induces individuals to extend some desirable productive effort. This determines individual encroachment activities which in turn determine the proportion of aggregate production that fails to be...

This paper characterizes the optimal insurance contract in an environment where an informed agent can misrepresent the state of the world to a principal who cannot credibly commit to an auditing strategy. Because the principal cannot commit, the optimal strategy of the agent is not to tell the...

This paper studies a principal-agent relationship in a contractual crime setting. Suppose an agent and a principal sign a contract stipulating some transfer of funds from one player (say the agent) to the next (the principal) contingent on the state of the world announced by the first player. In...

We provide an experimental analysis of competitive insurance markets with adverse selection. Our parameterized version of the lemons' model (Akerlof 1970) in the insurance context predicts total crowding out of low-risks when insurers offer a single full insurance contract. The therapy proposed...

We provide a continuum of subsidy rules based on a performance indicator that induce a monopoly to choose the socially optimal production level. These subsidy rules result in a reduction of the amount of subsidy paid to the monopolist compared to the standard case where a constant subsidy rate...

We model the interactions between management regimes (municipal vs. delegated) and operating costs of water supply services in order to compare their performance and pricing. We estimate the models from panel data in France. We show that the choice between management regimes at the local...

We analyze duopolistic competition between horizontally differentiated firms selling durable goods or services subject to congestion. At each point of time, new customers buy one unit of the commodity from one of the firms, by comparing present prices and future congestion rates. We study the...

Local interactions refer to social and economic phenomena where individuals' choices are influenced by the choices of others who are `close' to them socially or geographically. This represents a fairly accurate picture of human experience. Furthermore, since local interactions imply particular...

This paper revisits the tragedy of the commons when agents have different capabilities in both production and encroachment activities, and can allocate their time between them. Under fairly general assumptions on production and encroachment technologies, an individual's expected income is convex...

We propose an overlapping generations economy where households care about relative consumption, the difference between their consumption and the consumption of their reference group. An individual's consumption is driven by the comparison of his lifetime income and the lifetime income of his...
