This study explores what determines employers' violations of the wage contracts of workers on H-1B temporary work visas, which occur when firms pay those workers below the promised prevailing or "market" wage. A theoretical framework is proposed that predicts more violations during economic...

Guest worker programs allow migrants to work abroad legally, and offer benefits to workers, firms, and nations. Guest workers are typically authorized to work only in specific labor markets, and are sponsored by, and must work for, a specific firm, making it difficult for guest workers to switch...

We address the impact of declining migration on the measurement of labor market health. We first document an historically significant decline in the growth rate of the U.S. foreign born population since 2000. A decomposition shows that nearly two-thirds of the decline can be attributed to...

Guest workers on visas in the United States may be unable to quit bad employers due to barriers to mobility and a lack of labor market competition. Using H-1B, H-2A, and H-2B program data, we calculate the concentration of employers in geographically defined labor markets within occupations. We...

We present new theory and empirical evidence concerning racial discrimination in promotions. In our model, promotions signal worker ability. When tasks differ substantially across levels of a job hierarchy, the opportunity cost (in terms of foregone output) of not promoting qualified nonwhite...

In a multi-task, market-based promotion tournament model, under different environments concerning employer learning about worker ability, it is shown that:i) Asymmetric learning in multi-task jobs is a necessary condition for "strategic shirking" (i.e., underperforming on certain tasks to...

Surveying employment-related newspaper advertisements over several centuries, we identify four eras (neither workers nor firms posted ads, mostly workers posted, mostly firms posted, both parties posted). These eras correspond to alternative equilibria in a strategic coordination game describing...
