Market Liberalization: Price Dispersion, Price Discrimination and Consumer Search in the German Electricity Markets

Klaus Peter Gugler, Vienna University of Economics and Business; European Corporate Governance Institute (ECGI), Sven Heim, Centre for European Economic Research (ZEW), Maarten Janssen, University of Vienna - Faculty of Business, Economics, and Statistics, and Mario Liebensteiner, Vienna University of Economics and Business study Market Liberalization: Price Dispersion, Price Discrimination and Consumer Search in the German Electricity Markets.

ABSTRACT: We study how consumer search affects pricing in markets with incumbents and entrants using panel data on German electricity retail markets. Consumers observe the baseline price of the incumbent and decide whether or not to search. Incumbent providers can price discriminate between searching and loyal consumers. Empirically we show that local incumbents increase their baseline rate while entrants decrease their tariffs if consumer search increases. Moreover, the incumbent price discriminates more strongly in markets with more consumer search. Using a theoretical model, we show that these pricing patterns are consistent with the strategic interaction of profit-maximizing firms.
