The distribution of income, the rate of pay raises, and the mobility of employees is crucial to understanding labor economics. Although research abounds on the distribution of wages across individuals in the economy, wage differentials within firms remain a mystery to economists. The first...

How and by how much do supervisors enhance worker productivity? Using a company-based data set on the productivity of technology-based services workers, supervisor effects are estimated and found to be large. Replacing a boss who is in the lower 10% of boss quality with one who is in the upper...

In this paper, we display the tools and principles of personnel economics through a series of models aimed at addressing the questions posed above. We focus on the building blocks that form the foundation of personnel economics: the assumptions that both the worker and the firm are rational...
