Data and Code for "Market Structure, Oligopsony Power, and Productivity"

I examine the effects of oligopsony power on allocative efficiency and income redistribution by studying a size regulation in the Chinese tobacco industry that led to ownership consolidation. I show that separate identification of input price markdowns, goods price markups, and productivity is challenging when a subset of inputs is non-substitutable, which often holds for materials, and construct and estimate a model to overcome this challenge. I find that the regulation increased input price markdowns by 37% on average. This increase in oligopsony power led to a decline in allocative efficiency and redistributed income away from rural households.
