We study the effect of borrowing limits on welfare in several versions of exchange and production economies. There is a "quantity" effect of a larger borrowing limit which is beneficial for liquidity constrained agents, but essentially irrelevant otherwise. There is also a "price effect" which...

We explore the accumulation of capital in the presence of limited insurance against idiosyncratic shocks, borrowing constraints and endogenous labor supply. In the exogenous labor supply case (e.g. Aiyagari 1994, Huggett 1997), the presence of limited insurance increases the demand for savings...

We construct and calibrate a general equilibrium business cycle model with unemployment and precautionary saving. We compute the cost of business cycles and locate the optimum in a set of simple cyclical fiscal policies. Our economy exhibits productivity shocks, giving firms an incentive to hire...

We study the effect of market incompleteness in a search model of the labor market in which the distribution of idiosyncratic uncertainty is determined endogenously. We show that costly search introduces a wealth effect at low levels of wealth such that poor agents may find optimal not to look...

Our aim is to provide insights into some basic facts of US government debt management by introducing simple financial frictions in a Ramsey model of fiscal policy. We find that the share of short bonds in total U.S. debt is large, persistent, and highly correlated with total debt. A well known...
