We analyze the sustainability of intergenerational transfers in politico-economic equilibrium. We argue that these transfers naturally arise in a Markov perfect equilibrium in the fundamental state variables. In contrast to earlier literature, our explanation does not resort to altruism,...

The present paper constructs possible baseline economies with an aging population to analyze Social Security reform plans, using an overlapping generations (OLG) model with heterogeneous households. In this model, households receive idiosyncratic working ability shocks and mortality shocks....

This paper compares wealth portfolios across countries. The household sector in the US and Canada owns much more financial wealth, and much less housing wealth, than the household sector in most of Europe. We address this fact using a calibrated two sector growth model with endogenous financial...

This paper investigate how the degree of credit market development is related to business cycle fluctuations in industrialized countries. I show that a business cycle model with collateral constraints generate a negative relation between the volatility of the cyclical component of output and the...

We study optimal capital taxation in a limited commitment environment. Our environment consists of a continuum of households with idiosyncratic labor shocks, who have access to a complete contingent claims market. Financial contracts are not perfectly enforceable; as in Kehoe and Levine (1993),...

This paper studies the effects of a flat-tax reform in a dynamic, general equilibrium model with heterogeneous agents and occupational choice. Each agent has a choice to be a worker or to establish a firm and become an entrepreneur with a limited ability to borrow in financial markets. Because...
