Jaison R. Abel and Richard Deitz:

Although the unemployment rate of workers with a college degree has remained well below average since the Great Recession, there is growing concern that college graduates are increasingly underemployed—that is, working in a job that does not require a college degree or the skills acquired through their chosen field of study. Our recent New York Fed staff report indicates that one important factor affecting the ability of workers to find jobs that match their skills is where they look for a job. In particular, we show that looking for a job in big cities, which have larger and thicker local labor markets (that is, bigger markets with many buyers and sellers), can give workers a better chance to find a job that fits their skills.

Theoretical research in urban economics suggests that the large and thick local labor markets found in big cities can increase the likelihood of job matching and improve the quality of these matches. These benefits arise because big cities have more job openings and offer a wider variety of job opportunities that can potentially fit the skills of different workers. In addition, a larger and thicker local labor market makes it easier and less costly for workers to search for jobs.
