Building on the seminal paper of Ordover, Saloner and Salop (1990), I study the role of reputation building on foreclosure in laboratory experiments. In one-shot interactions, upstream firms can choose to build a reputation by revealing their price history to the current upstream competitor. In...

Im Dezember vergangenen Jahres hat das Europäische Parlament einer Vorlage der Europäischen Kommission zugestimmt, wonach die Schutzrechte für das Design von Auto-Ersatzteilen eingeschränkt werden sollen. Für Ersatzteile, deren Design maßgeblich für ihre Funktionalität oder ihr äußeres...

We present a potentially benign naked exclusion mechanism that can be applied to sequential innovation; a non-patentable original innovation by the incumbent supplier fosters derivative innovation by rivals. In the absence of an appropriate legal framework, the original innovator’s equilibrium...

This paper provides an economic analysis of recent vertical and horizontal mergers in the U.S. industry for audiovisual media content, including the AT&T-Time Warner and the Disney-Fox mergers. Using a theory-driven approach, we examine economic effects of these types of mergers on market...

We study zero-rating, a practice whereby an Internet service provider (ISP) that limits retail data consumption exempts certain content from that limit. This practice is particularly controversial when an ISP zero-rates its own vertically integrated content, because the data limit and ensuing...

A manufacturer chooses the optimal retail market structure and bilaterally and secretly contracts with each (homogeneous) retailer. In a classic framework without asymmetric information, the manufacturer sells through a single exclusive retailer in order to eliminate the opportunism problem....

We investigate the possibility for two vertically related firms to at least partially collude on the wholesale price over an in.nite horizon to mitigate or eliminate the e¤ects of double marginalisation, thereby avoiding contracts which might not be enforceable. We characterise alternative...

We analyze a situation in which two horizontally differentiated firms compete in two-part tariffs (i.e., a linear and fixed price), and some consumers are not informed about the linear per-unit price. We show that there is a non-monotone relationship between the degree of consumer-side...

This paper analyzes the role of the reference period in assessing switching costs in retroactive rebates. A retroactive rebate allows a firm to use the inelastic portion of demand as leverage to decrease price in the elastic portion of demand, thereby artificially increasing switching costs of...

In some markets vertically integrated firms sell directly to final customers but also to independent downstream firms with whom they then compete on the downstream market. It is often argued that resellers intensify competition and benefit consumers, in particular when wholesale prices are...
