We use a novel data set with exact price quotes from virtually all German gasoline stations to empirically investigate how a temporary variance in local market structure - induced by restricted opening hours of specific players - affects price competition. We focus on stations selling gasoline...

Price levels and movements on gasoline and diesel markets are heavily debated among consumers, policy-makers, and competition authorities alike. In this paper, we empirically investigate how and why price levels differ across gasoline stations in Germany, using eight months of data from a novel...

Der vorliegende Beitrag befasst sich mit aktuellen Wettbewerbsproblemen im deutschen Lebensmitteleinzelhandel. Im Mittelpunkt der Analyse stehen der zunehmende Konzentrationsprozess und seine Determinanten. Darauf aufbauend diskutieren wir Aspekte der Marktabgrenzung insbesondere im Hinblick auf...

In der wettbewerbsbehördlichen Fallpraxis gewinnt die Bestimmung von Nachfragemacht zunehmend an Bedeutung. Bei Fusionsvorhaben im Einzelhandel kann Nachfragemacht ein Hauptgrund für eine Untersagung bzw. für Auflagen sein. In diesem Beitrag wird die aktuelle Diskussion zur Bestimmung von...

This paper analyses the extent of inter-format retail competition between supermarkets, discounters and drugstores in Germany, using data from the German market for diapers. We estimate a random coefficient logit model at the individual household level. Based on consumer substitution patterns,...

Given various recent antitrust investigations on the retail sector, we deal with uncovering demand systems substitution patterns for a particular market (diapers) to investigate the inter-format competition (supermarkets vs. discounters vs. drugstores). Using the uncovered demand system we...

Research on bargaining power in vertical relationships is scarce. It remains particularly unclear which factors drive bargaining power between negotiating parties in a vertical structure. We use a demand model where consumer demand determines the total pie of industry profits. Moreover, we apply...

We use a novel data set with exact price quotes from virtually all German gasoline stations to empirically investigate how a temporary variance in local market structure induced by restricted opening hours of specific players affects price competition. We find that, during their hours of...

We examine how different pass-through rates, from input- to final consumer prices, and different vertical contracts affect upstream market definition. Our theory model predicts that, under reasonable conditions, higher pass-through rates lead to definitions of larger upstream markets. Data...
