Our paper investigates whether the valuation effect caused by a large risk premium and a low risk-free rate can help to explain the enormous US current account and trade deficit observed in the past decade. To answer this question, we set up an endowment growth model in which investors are...

This paper analyzes and computes the equilibria of economies with large numbers of heterogeneous agents who have different asset trading technologies, preferences, and beliefs. We illustrate the value of our method by using it to evaluate the implications of these heterogeneities through several...

The impact of fully anticipated inflation is systematically studied in heterogeneous agent economies with an endogenous labor supply and portfolio choices. In stationary equilibrium, inflation nonlinearly alters the endogenous distributions of income, wealth, and consumption. Small departures...
