Inspired by the current debate over the future of the monetary union in Europe, this paper provides a simple model for the determination of the conditions of survival of the common good, which requires the creation of an effective fiscal union. We highlight the importance of institutional design...

A common belief among monetary theorists is that monetary equilibria are tenuous due to the intrinsic uselessness of fiat money (Wallace (1978)). In this article we argue that the tenuousness of monetary equilibria vanishes as soon as one introduces a small perturbation in an otherwise standard...

We modify the standard Kiyotaki-Wright model (1993) in order to add an autarkic option in the agents' choice set. The value of the autarkic option is independent of strategic coordination problems and represents a sort of reservation utility with respect to exchange activity. This allows us to...

Fixed-path methods (FPMs) were introduced to manage situations where several individuals jointly operate a single technology (see [4]). In the production context, they consist in allocating marginal increments of output according to a proportions vector which changes along an arbitrary path....

This paper provides a necessary and sufficient condition for the existence of nonautarkic contract in a risk sharing model with two-sided lack of commitment. Verifying the condition takes just one Gaussian elimination of a matrix.
