We consider an extension of a general equilibrium model with incomplete markets that considers cash-in-advance constraints. The total amount of money is supplied by an authority, which produces at no cost and lends money to agents at short term nominal rates of interest, meeting the demand....

In a multi-period, multi-commodity economy with stock markets, we try to extend the work of Drèze (1974) to define the behaviour of the firms. We exhibit first order necessary conditions for a constrained Pareto optimal allocation. The financial constraints lead to non-collinear supporting spot...

Static competitive equilibria in economies with incomplete markets are generically constrained suboptimal. Allocations induced by strategic equilibria of imperfectly competitive markets are also generically inefficient. In both cases, there is scope for Pareto-improving amendments. Considering...

We are interested in proving an equilibrium existence result in a general equilibrium model with incomplete nominal asset markets. When we relax the assumption of strict positivity of initial endowments, then, as it is the case for every general equilibrium existence problem, we need to...

In OLG framework, it is generally admitted that PAYG pension system generates a lower capital accumulation, a higher level of interest rate but is more inequality reducing. By taking into account different assets returns and unequal access to them, we find that the PAYG pension system generates...

This paper studies a simple stochastic two-period general equilibrium model with money, an incomplete market of nominal assets, and a competitive banking system, intermediate between consumers and a Central Bank. There is a finite number of agents, consumers and banks. Default is not permitted....
