Using the Survey of Doctoral Recipients, the magnitude and consequences of job mismatch are estimated for Ph.D.s in science. Approximately one-sixth of academics and nearly one-half of nonacademics report some degree of mismatch. The influence of job mismatch is estimated for three job outcomes:...

This paper develops a theoretical framework for analyzing contracting imperfections in long-term employment relationships. We focus chiefly on limited enforceability and limited worker liquidity. Inefficient severance of employment relationships, payment of efficiency wages, the relative...

Labor income indices are created for groupings of individuals, using data from the Panel Study of Income Dynamics. People are grouped by a clustering algorithm based on an estimated transition matrix between jobs, by education level, and by skill category. The groupings are defined so that...

This paper studies the efficient agreements about the dependence of workers' earnings on employment, when the employment level is controlled by firms. The firms ' superior information about profitability conditions is responsible for this form of contract governance. Under plausible assumptions,...

Cyclical patterns in earnings can arise when contracts between firms and their workers are incomplete, and when workers cannot borrow or lend so as to smooth their consumption.

This paper describes measurement of a self-employment rate and the important role the agricultural sector plays in any analysis of the determinants of self-employment. The determinants of the self-employment rate are modeled using a panel of 23 countries for the period 1966-1996. A similar...

Employee ownership in U.S. companies has grown substantially in the past 20 years. This paper reviews and provides some meta-analyses on the accumulated evidence concerning the prevalence, causes, and effects of employee ownership, covering 25 studies of employee attitudes and behaviors, and 27...
