In this paper, we show that in a dynamic general equilibrium economy, the presence of moral hazard need not induce large cuts in optimal unemployment insurance benefits. We find that it takes a quite large proportion of "shirkers" to bend the generosity of the optimal unemployment insurance...

Sharing risks is one of the essential economic roles of families. The importance of this role increases in the amount of uncertainty that households face in the labor market and in the degree of incompleteness of financial markets. We develop a theory of joint household search in frictional...

This paper posits a notion of the value of an individual's human capital and the associated return on human capital. These concepts are examined using U.S. data on male earnings and financial asset returns. We find that (1) the value of human capital is far below the value implied by discounting...

This paper investigates the long-run effects of open-market operations on the distributions of assets and prices in the economy. It offers a theoretical framework to incorporate multiple asset holdings in a tractable heterogeneous-agent model, in which the central bank implements policies by...

While it is well established that across-country taste differences are associated with "home market effects", there is very limited analysis of how such preference heterogeneity impacts the aggregate volume of trade and the welfare gains from liberalization. I develop a structural model of...

Developing countries have experienced an outstanding outflow of skilled workers (brain- drain) over the last several decades. Additionally, migrants tend to be tied to their country of birth, since they send a large amount of remittances to their relatives. Furthermore, migration is not...

Theoretical formulations of dynamic heterogeneous-agent economiestypically include a distribution as an aggregate state variable. This paperintroduces a method for computing equilibrium of these models by including a distribution directly as a state variable if it is finite-dimensional or a fine...

This paper applies Canova JAE 1994 methodology to perform a thorough sensitivity analysis for the Aiyagari QJE 1994 economy. This is a calibrated GE model with incomplete markets and uninsurable income risk, designed to quantify the size of precautionary savings and the degree of wealth...

Business cycles reflect changes over time in the amount of trade between individuals. In this paper we show that incorporating explicitly intra-temporal gains from trade between individuals into a macroeconomic model can provide new insight into the potential mechanisms driving economic...

We study the dynamics of a Lucas-tree model with finitely lived agents who "learn from experience." Individuals update expectations by Bayesian learning based on observations from their own lifetimes. In this model, the stock price exhibits stochastic boom-and-bust fluctuations around the...
