Abstract

Vertical integration in environments without foreclosure, or more generally without any obstacles that restrict competition in the market, and subsidization of firms are two separate mechanisms that have pro-competitive effects. In this paper we show that subsidization can corrode the positive welfare effects of vertical integration, as the latter induces the government to subsidize firms’ output to a lesser extent. This causes an output reduction that lowers consumer surplus.
