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...

This paper constructs a dynamic model of health insurance to evaluate the short- and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions...

A model of self-enforcing stochastic monitoring with investment and production is developed. The optimal contract leads to debt-like and equity-like claims on the firm that are held by symmetrically informed outside investors and rationalizes the separation of these claims in order to...

households with better insurance against idiosyncratic risk adopt more `aggressive' trading strategies in equilibrium.

This paper constructs a dynamic model of health insurance to evaluate the short- and long-run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions...
