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...

The authors construct a model of a dynamic economy in which lenders cannot force borrowers to repay their debts unless the debts are secured. In such an economy, durable assets play a dual role: not only are they factors of production but they also serve as collateral for loans. The dynamic...

We develop an equilibrium search model that incorporates job-to-job transitions, exhibits instances of replacement hiring, and conceptually distinguishes between job and worker flows. We propose a notion of competitive equilibrium for random-matching environments and study the extent to which it...

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...

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...

This goal of this paper is to extend existing search-theoretic models of fiat money, which until now have assumed that the price level is exogenous, by explicitly incorporating bilateral bargaining. This allows the determination of the price level endogenously and leads to additional insights...

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...
