Working papers
Collective Bargaining and Spillovers in Local Labour markets, R&R Journal of the European Economic Association (JEEA). Collective bargaining in South Africa triggers wage spillovers via interfirm worker flows, with profit margins declining as firms adjust. Discussion paper, Twitter.
When do employers share? Rent sharing, monopsony and minimum wages, with Joshua Budlender. We identify a novel theoretical prediction, with supportive evidence in line with monopsony, that firms just-constrained by minimum wages absorb positive productivity shocks as excess profits, limiting wage and employment increases. Working paper.
