Privately informed owners securitizing assets signal positive information by retaining sufficient interest. Signaling provides social benefits, allowing uninformed investors to insure without fearing adverse selection. Instead of signaling, owners of high value assets may prefer a pooling...

This paper deals with risk-sharing problems between many agents, each of whom having a strictly concave law invariant utility. In the special case where every agent's utility is given by a concave integral functional of the quantile of her individual endowment, we fully characterize the optimal...

This paper examines the formation of risk sharing networks in the rural Philippines. We find that geographic proximity–possibly correlated with kinship–is a major determinant of mutual insurance links among villagers. Age and wealth differences also play an important role. In contrast,...

This paper explores risk-sharing and equilibrium in a general equilibrium set-up wherein agents are non-additive expected utility maximizers. We show that when agents have the same convex capacity, the set of Pareto-optima is independent of it and identical to the set of optima of an economy in...

This paper considers a class of one dimensional calculus of variations problems with monotonicity and comonotonicity constraints arising in economic and financial models where law invariant concave criteria (or law invariant convex measures of risk) are used. Existence solutions, optimality...

What determines equilibrium securitization levels, and should they be regulated? To address these questions we develop a model where originators can exert unobservable effort to increase asset quality, subsequently having private information regarding quality when selling ABS to rational...

What determines securitization levels, and should they be regulated? To address these questions we develop a model where originators can exert unobservable effort to increase expected asset quality, subsequently having private information regarding quality when selling ABS to rational investors....

This paper examines what economic policy has learned from the contemporary developments in economic research and which lessons have been drawn from them for the formulation and the implementation of French economic policy. Advances in research are grouped under three headings: the intertemporal...

Central Banker’s Behaviour in an Uncertain EnvironmentSeveral recent papers are devoted to the examination of the central banker’s behaviour in an uncertain economic environment. This paper proposes, from a central banker’s point of view, a synthesis of the main sources of uncertainty as...

When countries decide to coordinate and form a coalition, an outsider country can take advantage of the situation and gain more than an insider, hence creating a free-rider problem that could threaten the stability of the coalition. But as far as the Euro zone is concerned, the emphasis put on...
