"This paper studies how optimal wage tax conclusions from the classic two-period life cycle model of human capital accumulation are affected by endogenizing the number of taxpaying workers. In the absence of a corrective policy, young individuals underinvest in human capital from a social...

We extend the nonparametric literature on partially identified probability distributions and use our analytical results to provide sharp bounds on the impact of universal health insurance on provider visits and medical expenditures. Our approach accounts for uncertainty about the reliability of...

On Dec. 10, 1995, the Philadelphia Eagles beat the Dallas Cowboys 20-17 in overtime after the Cowboys twice failed near the end of regulation to convert on a fourth down play in their own territory. Coach Switzer's decision not to punt was roundly vilified in the national sports media as...

In this paper, we investigate the complex interrelations among work-time, wages, and health identified in the Grossman model of the demand for health. Hansen's generalized method of moments techniques are employed to estimate a 3-equation simultaneous model designed to capture the time dependent...

In light of widespread concerns about the reliability of self-reported disability, we investigate what can be learned about the prevalence of work disability under various assumptions on the reporting error process. Developing a nonparametric bounding framework, we provide tight inferences under...

This paper considers the relative efficiency of ad valorem and unit taxes in imperfectly competitive markets. We provide a simple proof that ad valorem taxes are welfare-superior to unit taxes in the short run when production costs are identical across firms. The proof covers differentiated...

Although there is a long-standing interest in the labor market behavior of older persons, there is little consensus on the reliability of self-reported indicators of health status. Rather than imposing the strong assumptions required to obtain point identification, Kreider and Pepper (2001,...
