Wholesale price discrimination with regulatory asymmetry

Abstract

This paper studies the welfare effects of wholesale price discrimination between downstream firms operating under different regulatory systems. I model a monopolistic intermediate good market in which production cost differences between downstream firms may be due to regulatory or technological asymmetries. Price discrimination reduces regulatory distortions but may lower productive efficiency. Therefore, price discrimination increases welfare if regulation is the dominant source of cost differences. This provides a novel welfare rationale for exempting wholesale markets from the recent ban on geo-blocking in the EU.
