The steady state general equilibrium and welfare consequences of health insurance reform are evaluated in a calibrated life-cycle economy with incomplete markets and endogenous labor supply. Individuals face uncertainty each period about their future health status, medical expenditures, labor...

This paper shows that a standard Real Business Cycle model driven by productivity shocks can successfully account for the 50 percent decline in cyclical volatility of output and its components, and labor input that has occurred since 1983. The model is successful because the volatility of...

We explore the quantitative implications of uncertainty about the length of life and a lack of annuity markets for life cycle consumption in a general equilibrium overlapping generations model in which markets are otherwise complete. Empirical studies find that consumption tends to rise early in...

A unified growth theory is developed that accounts for the roughly constant living standards displayed by world economies prior to 1800 as well as the growing living standards exhibited by modern industrial economies. Our theory also explains the industrial revolution, which is the transition...

We study the effects of on-the-job skill accumulation on average hours worked by age and the volatility of hours over the life cycle in a calibrated general equilibrium model. Two forms of skill accumulation are considered: learning by doing and on-the-job training. In our economy with learning...

Past government spending in Japan is currently imposing a significant fiscal burden that is reflected in a net debt to output ratio near 150 percent. In addition, the aging of Japanese society implies that public expenditures and transfers payments relative to output are projected to continue to...
