A product market is concentrated when a few firms dominate the market. Similarly, a labor market is concentrated when a few firms dominate hiring in the market. Using data from the leading employment website CareerBuilder.com, we calculate labor market concentration for over 8,000...

Adam Smith alleged that secret employer collusion to reduce labor earnings is common. This paper examines an important case of such behavior: no-poach agreements through which technology companies agreed not to compete for each other’s workers. Exploiting the plausibly exogenous timing of a US...

The neoclassical growth model assumes fixed labor supply and competitive labor markets. Is it harmless to ignore monopsonistic power in the neoclassical growth model? The paper argues that it is not, especially if a growth model needs to be consistent with the long-run dynamics of the labor...

This study estimates and decomposes recruitment elasticity, a key measure of employer market power, across job-matching stages using data from Japan's largest job-matching intermediary. On average, recruitment elasticity is negative but not statistically significantly different from zero....

We estimate the labor market power of over 13,000 manufacturing establishments across 82 low and middle-income countries around the world. Within local labor markets, larger and more productive firms have higher wage markdowns and pay lower wages. Labor market power across countries exhibits a...

This paper provides a comprehensive assessment of the margins along which firms in Norway respond to increased union density, using legislative changes in the tax deductibility of union dues as a quasi-exogenous shock to firm-level unionization rates. Despite higher personnel costs driven by a...

It is a well-known fact that temporary agency workers have to accept high pay penalties. However, remarkably little is known about the remuneration of workers who are frequently employed in this sector or who are employed for a substantial length of time. Based on a rich administrative data set,...

We model educational investment and labor supply in a competitive economy with home and market production. Heterogeneous workers are assumed to have different productivities both at home and in the workplace. We investigate the degree to which there is under-investment in human capital, and...

The prevailing labor market models assume that minimum wages do not affect the labor supply schedule. We challenge this view in this paper by showing experimentally that minimum wages have significant and lasting effects on subjects' reservation wages. The temporary introduction of a minimum...

We study the relationship between offshoring and the prevalence and intensity of labor market imperfections at the firm level in Belgium and the Netherlands. Wage-markup pricing stemming from workers' monopoly power is more prevalent than wage-markdown pricing originating from firms' monopsony...
