In this paper, I address the simple question "What types of employees have been steadily paid more by what type of employers?" and I suggest that rising market concentration has a significant structural impact on the wage differentials between white and blue-collar workers. The innovative...

The paper argues that wage dispersion between white-collar and blue-collar workers has caused the rise and expansion of pension funds in a direct and long-run structural manner in the USA. Using data from the Saez-Zucman and the St. Louis Fed's FRED datasets, the argument is empirically analysed...

This study offers a unified explanation for the perplexing fact that the education premium rises more for low-experienced workers, while the experience premium increases mainly for low-educated labor. The interaction of signaling, employer learning and credit constraints resolves this puzzle....

This study investigates the effects of labor costs on firms' capital investments and stock returns. I estimate wage premia across U.S. industries and show that the negative investment-return relation implied by q-theory is steeper for firms paying high wage premia than for firms paying low wage...

This paper studies the long term consequences on workers' labour earnings of the credit crunch induced by the 2007-2008 financial crisis. We study the evolution of both employment and wages in a large sample of Italian workers followed for nine years after the start of the crisis. We rely on a...

Wage inequality has risen in many countries over recent decades. At the same time, production has become increasingly concentrated in a small number of firms. In this paper, we show that these two phenomena are linked. Theoretically, we show that shocks that increase concentration will also lead...

This paper studies how wages respond to a sudden change in employer concentration. It exploits a reform that deregulated the Swedish pharmacy market, which until 2009 was a monopoly. The reform involved a substantial increase in the number of employers on the pharmacy labor market. However, the...

What is the impact of firms' productivity shocks on workers' labor earnings? To answer this question, we propose a novel approach to identify firms' productivity shocks that combines a nonparametric production function estimation method with a set of two-way fixed effect regressions to control...
