摘要
This paper studies indirect network effects on firm entry and product variety. Specifically, we quantify how technologically advanced international firms in an open market contribute to the development of a complementary market by encouraging entry (a cross-market spillover effect), which in turn benefits domestic firms in the open market by increasing their profits from new products (a within-market spillover effect). Our context is the Indian mobile phone industry during the 4G rollout, consisting of the cell phone market (which sells phones) and the wireless service market (which sells plans). International firms play an important role in the cell phone market. Using data on sales, prices, and product availability in these two markets, we estimate a structural model of consumer demand, carriers’ 4G network expansions, and cell phone firms’ product choices. Our estimates yield four findings supporting the spillover effects. Using counterfactual simulations, we quantify how the presence of international cell phone firms accelerates 4G network deployment, increases 4G phone variety, and benefits consumers.
