In Lazear's (1979) model of efficient long-term incentive contracts, employers impose involuntary retirement based on age. This model implies that age discrimination laws, which bar involuntary terminations based on age, discourage the use of such contracts and reduce efficiency. Alternatively,...

The question of the effects of race and sex discrimination laws on relative economic outcomes for blacks and women has been of interest at least since the Civil Rights and Equal Pay Acts passed in the 1960s. We present new evidence on the effects of these laws based on variation induced first by...

We study the effect of minimum wage increases on employment in automatable jobs – jobs in which employers may find it easier to substitute machines for people – focusing on low-skilled workers for whom such substitution may be spurred by minimum wage increases. Based on CPS data from...

We examine the effects of provider choice policies on workers' compensation medical and indemnity costs. We find no difference in average medical costs between states where policies give employers control over the choice of provider and states where policies instead give workers the most...

I discuss the econometrics and the economics of past research on the effects of minimum wages on employment in the United States. My intent is to try to identify key questions raised in the recent literature, and some from the earlier literature, which I think hold the most promise for...

We estimate the effect of opioid prescriptions on the duration of temporary disability benefits among workers with work-related low back injuries. We use local opioid prescribing patterns to construct an instrumental variable that generates variation in opioid prescriptions but is arguably...

We provide evidence from a field experiment in all 50 states on age discrimination in hiring for retail sales jobs. We relate measured age discrimination – the difference in callback rates between old and young applicants – to state variation in anti-discrimination laws protecting older...

We investigate the impact of union strength on changes in nonunion wages and employment. The prevailing model in this area is the threat model, which predicts that increases in union strength cause increases in nonunion wages and decreases in nonunion employment. In testing the threat model, we...

We use data from a survey of employers to investigate how Affirmative Action in recruiting and hiring influences hiring practices, personnel policies, and ultimately employment outcomes. Our results show that Affirmative Action increases the number of recruitment and screening practices used by...

This paper provides evidence on a wide set of margins along which labor markets can adjust in response to increases in the minimum wage, including wages, hours, employment, and ultimately labor income, representing the central margins of adjustment that impact the economic well-being of workers...
