This paper builds a dynamic general equilibrium model of cities and uses it to analyze the role of local housing markets and moving costs in determining the character and extent of labor reallocation in the US economy. Labor reallocation in the model is driven by idiosyncratic city-specific...

Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practise local population changes are dominated by variation in net migration, and we argue that understanding gross migration is essential to quantify how net migration may slow population...

The authors construct a dynamic general equilibrium model of cities and use it to estimate the effect of local agglomeration on per capita consumption growth. Agglomeration affects growth through the density of economic activity: higher production per unit of land raises local productivity....

This paper develops a Walrasian equilibrium theory of establishment dynamics and matching frictions and uses it to analyze business cycle fluctuations. Two scenarios are considered: one in which the matching process is subject to congestion externalities and another in which it is not. The paper...

This paper develops a Walrasian equilibrium theory of establishment level dynamics and matching frictions and uses it to evaluate the effects of congestion externalities in the matching process and determine the government interventions that are needed to implement a Pareto optimal allocation....

I consider a real business cycle model in which agents have private information about an idiosyncratic shock to their value of leisure. I consider the mechanism design problem for this economy and describe a computational method to solve it. This is an important contribution of the paper since...

In this paper, I explore how optimal aggregate dynamics can be shaped by the presence of moral hazard in unemployment insurance. I also analyze the optimal provision of unemployment insurance and the implications for the amount of cross-sectional heterogeneity. The economy that I consider embeds...

I consider a neoclassical growth model with endogenous labor supply in which agents have private information about their idiosyncratic value of leisure. A key assumption is that these shocks follow a persistent stochastic process over time. For this economy I solve the economy-wide mechanism...

I consider a real business cycle model in which agents have private information about the i.i.d. realizations of their value of leisure. For the case of logarithmic preferences I provide an analytical characterization of the solution to the associated mechanism design problem. Moreover, I show a...

This paper introduces a general method for computing equilibria with heteroge- neous agents and aggregate shocks that is particularly suitable for economies with private infor- mation. Instead of the cross-sectional distribution of agents across individual states, the method uses as a state...
