We make two main contributions to the literature on work-related injury risk and economic outcomes in the context of American professional football. One is to examine an increasingly important specific injury, concussions, and compare its subsequent economic effects to those of other types of...

We examine the importance of possible non-random attrition to an econometric model of life cycle labor supply including joint nonlinear taxation of wage and interest incomes and latent heterogeneity. We use a Wald test comparing attriters to nonattriters and variable addition testing based on...

Similar to other workers in industrial settings NFL running backs can choose to provide additional work effort with possible negative health consequences. We find that the most informative measure for running backs is yards gained after contact, which not only increases total rushing yards but...

March 2001 (Revised from April 2000). Objective: Assess the determinants of medical costs for depressed individuals. Method: Using medical insurance claims for a population of depressed individuals with employer provided insurance, we estimated multivariate models of the costs for general...

Objective: Assess the determinants of medical costs for depressed individuals. Method: Using medical insurance claims for a population of depressed individuals with employer provided insurance, we estimated multivariate models of the costs for general medical care, exclusive of costs for mental...

We examine theoretically and empirically the properties of the equilibrium wage function and its implications for policy. Our emphasis is on how the researcher approaches economic and policy questions when there is labor market heterogeneity leading to a set of wages. We focus on the application...

Our research addresses fundamental long-standing concerns in the compensating wage differentials literature and its public policy implications: the econometric properties of estimates of the value of statistical life (VSL) and the wide range of such estimates from about $0.5 million to about $21...
