Labor Monopsony in the United States

Abstract

Most labor markets are monopsonistic, meaning that employers have market power and can suppress wages below the competitive rate. Among the various sources of market power is concentration: the usually small number of employers who compete to offer a type of job to workers. At one time, economists assumed that labor markets were competitive, and largely ignored the phenomenon of labor market concentration. Recent empirical work, relying on newly available databases, has established that labor market concentration is a serious problem in the United States and may account for a wide range of pathologies, including low wages, inequality, and stagnant economic growth.
