The objective of this paper is to study the stationary monetary equilibria in a stochastic overlapping generations model with a general incomplete asset structure. It is proved that a stationary equilibrium with a non zero price of money generically exists and is locally isolated when there is...

We consider an economy where individuals face uninsurable risks to their human capital accumulation, and study the problem of determining the optimal level of linear taxes on capital and labor income together with the optimal path of the debt level. We show both analytically and numerically that...

When individuals' labor and capital income are subject to uninsurable idiosyncratic risks, should capital and labor be taxed, and if so how? In a two period general equilibrium model with production, we derive a decomposition formula of the welfare e ects of these taxes into insurance and...
