Seit der deutschen Wiedervereinigung vor 30 Jahren sind für den sogenannten Aufbau Ost nach Schätzungen mehr als zwei Billionen Euro aufgewendet worden. Dennoch unterscheidet sich der Osten Deutschlands in vielen Merkmalen noch immer vom Westen. Regionale ökonomische Unterschiede als Beleg...

This paper offers a new and broad insight into the landscape of German cartels, utilizing a unique dataset of all illegal horizontal cartels detected by the German Federal Cartel Office (FCO) between 1958 and 2004 and all legal cartels authorized during the same time period. We also provide the...

This paper estimates demand elasticities for the Turkish mobile telecommunication market. In contrast to most other studies, firm level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a...

This paper explores how consumers react towards price differentiation between on-net and off-net calls in mobile telecommunications - a pricing policy that is common in many mobile telecommunications markets. Based on a survey of 1044 students we demonstrate that some consumers may suffer from a...

This paper analyses the benefits of further market integration of European wholesale electricity markets. Major gains from trade are sill left unrealized due to (1) uncomplete market coupling of national wholesale markets, (2) isolated national regulation of capacity and reserve mechanisms (CRM)...

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,...

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 focus on stations selling gasoline...
