One of the central questions in corporate finance is whether investors prefer to receive their payouts from corporations in the form of cash dividends or as capital gains. We know that most firms pay dividends, even though doing so is costly in various ways. And we know that the market reaction...

We propose a simple model which embeds cost allocation games into a richer structure to take into account that information on costs can be itself costly. The model is an outgrowth of experience on cost allocation for consortia of municipalities dealing with garbage collection.

This paper posits itself in the stream of literature related to event studies and in particular the September 11th event. It is the first study to our knowledge that investigates the impact on the French financial market of September 11th, 2001 and September 21st, 2001. Was there any information...

This article analyses, for the first time, the financial impact on the French market of September 11th, 2001. Was there any information asymmetry around this date? How deep was the reaction of the French investors? This study measures the magnitude of the shock in the stock price process.

According to economic theory, health insurance raises medical care consumptions by inducing ex-post moral hazard behavior, it is to say the purchase of health care that individual value below their production cost. Nevertheless, among the economists community, some suggest that these additional...

In a differential information economy with quasi–linear utilities, monetary transfers facilitate the fulfillment of incentive compatibility constraints : the associated ex ante core is generically nonempty. However, we exhibit a well–behaved exchange economy in which this core is empty, even...

We study imperfect competition between insurers in a multiple-risk environment. In the absence of asymmetric information, equilibria are efficient, and we determine the degrees of specialization under which the specialized insurers are able or unable to capture the surplus. We show in contrast...

This paper presents a capital asset pricing model in the presence of asymmetric information and transaction costs. The model is a generalized version of Merton's (1987) model and Black's (1974) model. Empirical tests show a negative relation between the expected rate of return and the shadow...

We investigate a two-player zero-sum stochastic differential game in which the players have an asymmetric information on the random payoff. We prove that the game has a value and characterize this value in terms of dual viscosity solutions of some second order Hamilton-Jacobi equation.

In this paper we show that unlike in Bayesian frameworks asymmetric information does matter and can explain differences in common knowledge decisions due to ambiguous character of agents' private information. Agents share a common-but-not-necessarily-additive prior beliefs represented by...
