When the asset market is incomplete,there typically exist taxes on trades in assets and a redistribution of revenue in the asset market that are Pareto improving. The policy is anonymous,it economizes on complexity,and it re- sults in ex post Pareto optimal allocations ; it is publicly announced...

We prove generic existence of recursive equilibrium for overlapping generations economies with uncertainty. The result holds provided there is sufficient intragenerational household heterogeneity.

We prove generic existence of recursive equilibrium for overlapping generations economies with uncertainty and incomplete financial markets. Generic here means in a residual set of utilities and endowments. The result holds provided there is sufficient intragenerational household heterogeneity,...

In this paper the existence of unemployment is partly explained as being the result of coordination failures. It is shown that as a result of self-fulfilling pessimistic expectations, even at Walrasian prices, a continuum of equilibria results, among which an equilibrium with approximately no...

We study a financial market economy with a continuum of borrowers and pooling of borrowers’ promises. Under these conditions and in the absence of designing costs, utility-maximizing decisions of price-taking borrowers may lead to financial market incompleteness. Parametrizing equilibria...

In a three-period finite exchange economy with incomplete financial markets and retrading, we study the effects of the degree of incompleteness and of changes in the financial structure on asset price volatility. In what are essentially no aggregate risk economies, asset price volatility is a...
