We provide a characterization of an optimal insurance contract (coverage schedule and audit policy) when the monitoring procedure is random. When the policyholder exhibits constant absolute risk aversion, the optimal contract involves a positive indemnity payment with a deductible when the...

The aim of this paper is to analyze the impact of mutual firms on competition in the insurance market. We distinguish two actors in this market: mutual firms, which belong to their pooled members, and traditional companies, which belong to their shareholders. Our approach differs from the...

This paper generalizes the work of Rothschild and Stiglitz [1976], and is dealing with a game where two principals compete for an agent, when the agent has private information. The studied game has an efficient equilibrium, when the payoff of the principal does not depend on private information....

This paper considers a competitive insurance market under moral hazard and adverse selection, in which preventive efforts and self-protection costs are unobservable by insurance companies. Under reasonable assumptions, the conclusions of Rothschild and Stiglitz (1976) are preserved in our...

We analyze the incentives for a controlling shareholder to acquire silent or controlling shares in a competitor. When it occurs, the acquisition is detrimental to minority shareholders of his firm, or to the target, or even to both. The ownership structure of firms turns out to be a key...

This paper seeks to provide a ranking of information systems in a setting of contingent monitoring. Control strategies that make the acquisition of additional information conditional on observing certain outcomes largely elude the existing ranking criteria. We show that this happens because...

We provide sufficient conditions for the first-order approach in the principal-agent problem when the agent’s utility has the nonseparable form u(y−c(a)) where y is the contractual payoff and c(a) is the money cost of effort. We first consider a decision-maker facing prospects which cost...
