The Impact of the Internet on Retail Competition: Evidence from Technological Differences in Internet Access

Gebhardt, Georg (November 2010): The Impact of the Internet on Retail Competition: Evidence from Technological Differences in Internet Access. SFB/TR 15 Discussion Paper No. 345

Abstract

Does the internet increase competition? To address this question, I exploit two institutional details unique to Germany: (1) Some municipalities received glass fibre cables that cannot be upgraded to DSL; I use these municipalities as a treatment group with reduced online competition. (2) German law mandates resale price maintenance for books; I compare three retailing sectors, electronics (price competition), books (no price competition), and food (no online sales), to identify the effect of price competition: The effect of price competition is highly significant. Full broadband access reduces offline electronics retailers’ producer rents by 1.5 percent per year from 1999 to 2007.
