Many asset pricing puzzles can be explained when habit formation is added to standard preferences. We show that utility functions with a habit then gives rise to a puzzle of consumption volatility in place of the asset pricing puzzles when agents can choose consumption and labor optimally in...

We study the behavior of output, employment, consumption, and investment in Germany during the Great Depression of 1928-37. In this time period, real wages were countercyclical, and productivity and fiscal policy was procyclical. We use the neoclassical growth model to investigate how much these...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm-size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business, we show that, by reducing...

This paper considers the long-run distribution of capital holdings in a model with complete asset markets and progressive taxation. Households are assumed to be heterogeneous in their labor market productivity. We show that this model is capable of producing a nondegenerate determinate wealth...

This paper develops an overlapping agents model with age-specific mortality rates. The analytical framework also nests Blanchard's (1985, Journal of Political Economy 82, 1095–1117) "perpetual youth" model as a special, though perhaps not realistic, case. With age specific mortality...

This paper incorporates two features of housing in a life-cycle analysis of social security: housing as a durable good and housing market frictions. We find that both housing quantities and homeownership rates respond strongly to eliminating social security. Accordingly, the aggregate impacts of...

This paper studies Pareto-optimal risk-sharing arrangements in a private information economy with aggregate uncertainty and ex ante heterogeneous agents. I show how to implement Pareto-optima as equilibria when agents can trade claims to consumption contingent on aggregate shocks in financial...

This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...

The Tax Cuts and Jobs Act (TCJA) significantly altered how business income is taxed in the US. This paper provides a quantitative assessment of the distributional and macroeconomic effects of the TCJA, both in the short run and in the long run, using a life-cycle model with occupational choice...

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...
