In an economy where entrepreneurs with unequal "abilities" face alternative investment projects, which differ in degree of risk and productivity, we analyse the Nash equilibrium contracts arising from a banks-borrowers game in the context of asymmetric information. We show that, for a particular...

I study the constrained efficient allocations of a simple model of risk sharing and capital flows across countries assuming that each country cannot commit to fully repay its contract obligations. In the model, the degree of risk sharing and the amount of investment are interdependent. It is...

We analyze the Pareto optimal contracts between lenders and borrowers in a model with asymmetric information. The model generalizes the Rothschild-Stiglitz pure adverse selection problem by including moral hazard. Entrepreneurs with unequal “abilities” borrow to finance alternative...

In this paper, we consider economies with (possibly endogenous) solvency constraints under uncertainty. Constrained ine±ciency corresponds to a feasible redistribution yielding a welfare improvement beginning from ev- ery contingency reached by the economy. A sort of Cass Criterion (Cass [10])...

We construct an overlapping generations model with unemployment risk where wages, employment and severance payments are set through efficient bargaining between risk averse Unions and risk neutral firms. Assuming that a First Best cannot be achieved due to workers' shirking incentives, we...
