I show how to construct a stochastic long-lived overlapping generation’s model that is based on a non-stochastic model developed by Olivier Blanchard and Philippe Weil and that nests the RBC model as a special case. My innovation over previous work is to add an aggregate stochastic shock. I...

This paper describes the equilibrium of a discrete-time exchange economy in which consumers with arbitrary subjective discount factors and quasi-homothetic period utility functions follow linear Markov consumption and portfolio strategies. Explicit expressions are given for state prices and...

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 this article, I study the effect of worker heterogeneities on wages and unemployment within the context of a directed search model. A worker's productivity in a given firm depends both on their type and on a worker-firm specific component. Firms advertise unconditional wage offers, and hire...

This paper presents a model that explains why in the transition economies of Central and Eastern Europe an important output fall has been associated with price liberalization. Its key ingredients are search frictions and Williamsonian relation-specific investment implying that new investments...

In the course of ordinary business, commercial banks frequently encounter entrepreneurs seeking loans for the purpose of financing new or continuing projects. These entrepreneurs are frequently unrealistic, their perception having been biased by wishful thinking. Bankers are left with a...

The theory and the data in this Paper challenge the view that there is no structure in prices and allocations when markets are off equilibrium. Starting from the observation that price-taking usually applies only to small orders, a theory of equilibration is derived based on the assumption that...

This Paper considers the efficiency and convergence properties of dynamic processes of social and economic interactions, such as exchange economies, multilateral negotiations, merger and divestiture transactions, or legislative bargaining. The key general feature of the economy is that agents...

Pareto-improving economic reforms that also simultaneously achieve efficiency can be implemented through a strategy of ‘dual-track’ liberalization. Its success requires the feasibility of the original plan and its continued enforcement by the state. The Chinese experience demonstrates that...

We study the allocation of commodities through a two-stage hierarchy of competitive markets. Groups or countries trade at global prices while individuals within a group trade at local prices. We identify the free trade and the autarky equilibrium as polar cases. We show that no other two-stage...
