In this paper, we consider economies with (possibly endogenous) solvency constraints under uncertainty. Constrained inefficiency corresponds to a feasible redistribution yielding a welfare improvement beginning from every contingency reached by the economy. A sort of Cass Criterion (Cass (1972))...

In an economy where entrepreneurs with unequal ‘abilities’ face alternative investment projects, which differ in their 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...

The fiscal theory of the price level asserts that the price level is determined by the ratio of outstanding public nominal debt into the present value of real primary budget surpluses of the government. We here argue that the logic of the fiscal theory fails when at least part of the public debt...

This Paper investigates the relationship between risk and productive activity and the degree of financial intermediation in a model with moral hazard. Entreprenuers can simultaneously get credit from two types of competing institutions: ‘financial intermediaries’ and ‘local lenders’. The...

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 prove indeterminacy of competitive equilibrium in sequential economies, where limited commitment requires the endogenous determination of solvency constraints preventing debt repudiation (Alvarez and Jermann (2000)). In particular, we show that, for any arbitrary value of social welfare in...

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...

We analyse the Pareto optimal contracts between lenders and borrowers in a model with asymmetric information. The model is a generalization of the Rothschild-Stiglitz pure adverse selection problem to include moral hazard with limited liability contracts. Entrepreneurs with unequal ``abilities"...
