This paper essentially puts together procedures that are used in the computation of equilibria in models with a very large number of heterogeneous agents. It is not a complete description of all procedures used in the literature. It describes procedures that deal with infinitely lived agent...

We study, theoretically and quantitatively, the equilibrium of an unsecured consumer credit industry where credit-suppliers take deposits at a given interest rate and offer loans to households via a menu of credit levels and associated interest rates. The loan industry is competitive, with free...

Do the implications for business cycle issues change when we switch from studying infinitely-lived, representative-agent models to more sophisticated demographic structures with finitely-lived agents? This article addresses that question by using a large, overlapping-generations model that is...

In this paper we develop a model in which a country faces a balance of payments crisis if constraints on its international borrowing bind. We use the model to describe the dynamics of the trade balance, capital account, and balance of payments of a country that borrows to finance consumption...

The notion of skilled-biased technological change is often held responsible for the recent behavior of the U.S. skill premium, or the ratio between the wages of skilled and unskilled labor. This paper develops a framework for understanding this notion in terms of observable variables and uses...
