Suppose that n buyers each want one unit and m sellers each have one or more units of a good. Sellers post prices, and then buyers choose sellers. In symmetric equilibrium, similar sellers all post one price, and buyers randomize. Hence, more or fewer buyers may arrive than a seller can...

The authors analyze two unemployment insurance systems. In one, unemployed workers receive benefits, while those on reduced hours do not, as in North America (at least until recently). In the other, short-time compensation is paid to workers on reduced hours, as in Europe. The first system...

The authors analyze equilibrium in a labor market wherein it takes time for the workers to contact forms. Workers, assumed identical, repeatedly sell their labor services all through their work lives, choosing their search intensity endogenously. Identical firms attempt to maximize their...

The paper develops a model of directed search on the job in which transitions of workers between unemployment and employment and across employers are driven by heterogeneity in the quality of firm-worker matches. The equilibrium is such that the agents’ value and policy functions are...

This paper studies models of credit with limited commitment and, therefore, endogenous debt limits. There are multiple stationary equilibria plus nonstationary equilibria in which credit conditions change simply because of beliefs. There can be equilibria in which debt limits display...

The authors analyze economies in which individuals specialize in consumption and production and meet randomly over time in a way that implies that trade must be bilateral and quid pro quo. Nash equilibria in trading strategies are characterized. Certain goods emerge endogenously as media of...

We introduce home production into the neoclassical growth model and examine its consequences for development economics. In particular, we study the extent to which one can account for international income differences with differences in policies that distort capital accumulation. In models with...

This paper explores some macroeconomic implications of including household production in an otherwise standard real business cycle model. The authors calibrate the model on the basis of microeconomic evidence and long-run considerations, simulate it, and examine its statistical properties. They...
