The harmonization and integration of separate national energy markets to an interconnected internal European market is a top priority of the European Commission. However, as energy policy largely remains subject to national sovereignty, a higher degree of integration can cause unilateral...

The German response to the Fukushima nuclear power plant incident was possibly the most significant change of policy towards nuclear power outside Japan, leading to a sudden and very significant shift in the underlying power generation structure in Germany. This provides a very useful natural...

We provide an empirical assessment of the German interurban bus industry two years after its deregulation in January 2013. In addition to a general description of key developments of the industry, we use a unique route-level price data set to study both competitive interaction in general and the...

The duration of merger proceedings held by competition authorities is an important determinant of the efficiency of the entire merger control process. We use a dataset of 2953 Phase I and 92 Phase II investigations completed by the European Commission (EC) between 1999 and 2008 to examine the...

In electricity day-ahead markets organized as uniform price auction, a small reduction in supply in times of high demand can cause substantial increases in price. We use a unique data set of failures of generation capacity in the German-Austrian electricity market to investigate the relationship...

In many markets prices react stronger to rising than to falling costs. This asymmetric cost pass-through is still not fully understood, but recent theories suggest that asymmetric adjustments of consumers’ search efforts to rising and to falling prices may help to explain this. I use novel...

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...

Unbundling of vertically integrated utilities has become an integral element in the regulation of network industries and has been implemented in many jurisdictions. The idea of separating the network, as the natural monopoly, from downstream retailing, which may be exposed to competition, is...

We investigate the impact of consumer search and competition on pricing strategies in Germany's electricity retail. We utilize a unique panel dataset on spatially varying search requests at major online price comparison websites to construct a direct measure of search intensity and combine this...

We estimate the causal impact of restructuring aid granted by the European Commission between 2003 and 2012 on the survival and financial viability of aided firms. Using a comprehensive dataset we find that restructuring aid increases a firm's average survival time by 8 to 15 years and decreases...
