“…[19] or [24]) nor economists (e.g. [7] or [25]) have yet reached a consensus on an appropriate product market definition. The literature conveys the impression that most experts feel that the cluster market approach applied by the German Antitrust Authority may result in an incorrect depiction of the true competitiveness of the market.…”

“…It is one of the most common approaches in U.S. hospital merger control investigations and is to some extent reflected by the approach applied by the German Antitrust Authority [7]. However, the method requires a number of case specific ad hoc assumptions to avoid implausible definitions of the geographic market [11,13,22].…”

For example, Kuchinke and Kallfass argue in favor of the cluster market approach [7] while Jansen states that the cluster market assumption cannot be applied to the hospital market [24].

The correct definition of the product market and of the geographic market is a prerequisite for assessing market structures in antitrust cases. For hospital markets, both dimensions are controversially discussed in the literature. Using data for the German hospital market we aim at elaborating the need for differentiating the product market and at investigating the effects of different thresholds for the delineation of the geographic market based on patient flows. Thereby we contribute to the scarce empirical evidence on the structure of the German hospital market. We find that the German hospital sector is highly concentrated, confirming the results of a singular prior study. Furthermore, using a very general product market definition such as "acute in-patient care" averages out severe discrepancies that become visible when concentration is considered on the level of individual diagnoses. In contrast, varying thresholds for the definition of the geographic market has only impact on the level of concentration, while the correlation remains high. Our results underline the need for more empirical research concerning the definition of the product market for hospital services.JEL classification: I11; K21; L11; L40

“…In diesem Zusammenhang sind Behandlungsalternativen vor Ort und damit die Marktstruktur als wichtige Bestimmungsfaktoren für das Verhalten zu nennen. National lassen die Veröffentlichungen des Bundeskartellamts ähnliche Zusammenhänge für Deutschland vermuten [25,26]. Trotz dieser noch offenen Fragen dürften die hier vorgestellten Ergebnisse sowohl für die Öffentlichkeit als auch für politische Entscheidungsträger von Interesse sein.…”
