This paper evaluates four publicly discussed policy options to mitigate market power in the German wholesale electricity market. These four options are: a regulatory solution favoured by the Federal Ministry for Economics and Technology, the implementation of a day-ahead flow-based market...

We provide an extensive and general investigation of the effects on industryperformance - profits, social welfare and price-cost margins - of exogenously changing the number of firms in Cournot markets. This includes an in-depth exploration of the well-known trade-off between competition and...

As low-cost airlines or carriers excluded from international markets by regulation may seek to expand internationally in an indirect way through code-sharing agreements, they can choose partner airlines from among domestic or international carriers. The former case results in a...

Has the antitrust arsenal run out of novel theories or weapons? Think again. Recent scholarship has come to challenge conventional wisdom with the latest target of antitrust imagination being institutional investors, including diversified index funds. New economic research suggests that common...

Recent empirical studies demonstrate the significant extent to which a small number of well-known institutional investors have taken on large ownership interests in the majority of large U.S. public companies, including large ownership interests in horizontal competitors. The response to these...

Convenient scheduling, characterized by adequate flight frequency, is the main quality attribute for airline services. However, the effect of airline alliances on this important dimension of service quality has received almost no attention in the literature. This paper fills this gap by...

Recent merger cases involving the transfer of control over “big data” concluded that these mergers would not lead to competition problems because there was a sufficient number of other data sources available to the various players in the market. These merger cases implicitly accepted, but...

The literature shows that horizontal shareholding engenders significant anticompetitive effects and that no suitable instrument exists within European competition law which reliably and effectively can be applied to curtail such intrinsic effects. This Article analyses several proposals which...
