    Productive Efficiency and Ownership When Market Restructuring Affects Production Technologies

    While the link between the ownership and productive efficiency of firms has been discussed extensively, no consensus exists regarding the superiority of one or the other in non-competitive, regulated environments. This paper applies a flexibleproduction model to test for efficiency differences associated with ownership types while allowing the production to adapt to market restructuring over time. ...

    Abuse of Dominance and Antitrust Enforcement in the German Electricity Market

    In 2008, the European Commission investigated E.ON, a large and vertically integrated electricity company, for the alleged abuse of a joint dominant position by strategically withholding generation capacity. The case was settled after E.ON agreed to divest 5,000 MW generation capacity as well as its extra-high voltage network. We analyze the effect of these divestitures on German wholesale electricity ...

    Inference of Consumer Consideration Sets

    When consumers face a large number of alternatives, they tend to simplify the decision problem by reducing the number of available alternatives to a subset of relevant alternatives, i.e. a consideration set. Since consideration sets are typically unobserved, most studies in the demand literature have to assume a consideration model. If these consideration models are misspecified, the demand estimates ...

    Consumer Stockpiling and Sales Promotions

    In retailing markets of storable goods, consumer behavior is typically characterized by stockpiling. While existing research has developed rich models for such strategic consumer behavior, little is known about how sellers should ideally respond to it. In this paper, we provide insights into how frequency and depth of promotions affect consumer purchases and seller revenues in the long run. We show ...

    Changes in Common Ownership of German Companies

    Ownership of publicly listed German companies has undergone significant changes in recent years. The aim of this report is to document these trends since 2007 and analyze the extent to which firms that compete in the same product market are owned by the same investors, which is known as common ownership. We show that some large foreign institutional investors have overtaken domestic investors and now ...

    The Impact of Competition Policy Enforcement on the Functioning of EU Energy Markets

    We investigate the impact of competition policy enforcement on the functioning of European energy markets, and how sectoral regulation influences these outcomes. For this purpose, we compile a new dataset on the European Commission’s (EC) and EU member states’ competition policy decisions, and combine it with firm- and sector-level data. We find that EC merger policy has a positive and robust impact ...

    Companies with R&D Abroad Make Germany a Strong Research Location

    In recent years, German companies have invested more in research and development (R&D) abroad. After a prolonged plateau period, the proportion of investment abroad rose to around 35 percent; concurrently R&D expenditure in Germany has continued to rise sharply. Growth abroad did not occur at the expense of domestic research. Foreign companies in Germany have also invested more in R&D recently but ...
