Models of employer learning have two implications: first, the distribution of wages becomes more dispersed as a cohort of workers gains experience; second, the coefficient on an ability correlate that employers initially do not observe grows with experience. If learning by employers varies across occupations, both of these indicators of learning should covary positively across groups defined by a worker’s initial occupational assignment. This paper tests these implications using data from the NLSY79 and CPS. I find that there is significant heterogeneity in the employer learning process across occupations and that occupational assignment affects the learning process independently of education.

We examine the labor market effects of Secure Communities (SC), a police-based immigration enforcement policy implemented in 2008–13. Using variation in implementation across local areas and over time, we find that SC decreased the employment of likely undocumented immigrants. These effects are driven not only by deportations but also by adjustments among immigrants who remain in the United States. Importantly, SC also decreased the employment and hourly wages of US-born individuals. We provide support for two mechanisms that could explain this decline in labor demand: an increase in labor costs that decreases job creation and a reduction in local consumption.
