We propose a simple theory of predatory pricing, based on scale economies and sequential buyers (or markets). The entrant (or prey) needs to reach a critical scale to be successful. The incumbent (or predator) is ready to make losses on earlier buyers so as to deprive the prey of the scale it...

I present the following proposal: information revealed during non-cartel investigations by competition law enforcement authorities, such as evaluation of M&As or investigation of monopolization (dominance) conduct, should be directly used to investigate and prosecute cartels. Currently, in...

We develop a model in which two firms that have proposed to merge are privately informed about merger-specific efficiencies. This enables the firms to influence the merger control procedure by strategically revealing their information to an antitrust authority. Although the information improves...

Antitrust policy involves not just the regulation of anti-competitive behavior, but also an important deterrence effect. Neither scholars nor policymakers have fully researched the deterrence effects of merger policy tools, as they have been unable to empirically measure these effects. We...

Motivated by the general lack of empirical scholarship concerning the crossnational environment for competition policy, I present measures here of the overall resources dedicated to competition policy and the merger policy workload for thirty-two antitrust jurisdictions over the 1992-2007...

In comparing the historical circumstances in which ordoliberalism emerged with the socio-economic and political trends of today, this study identifies parallels that can provide useful insights into tackling current challenges in the digital age. On this basis, the study explores whether...

In the past 20 years, large digital platforms have made many acquisitions, mainly young and innovative startups. Few of them have been reviewed by competition authorities and little is known on their evolution after acquisition. This paper intends to fill in this gap by looking at the...

The model of perfect competition is one of the most famous, most important, and most misunderstood concepts in economics. Rather than aiming to be a full-blown model of real-world competitive markets, the perfect competition model isolates the decentralized coordination mechanism inherent in all...

Der vorliegende Beitrag wendet die dynamische Wettbewerbstheorie von Wolfgang Kerber und anderen auf aktuelle Fragen der Wettbewerbspolitik an. Damit zeigt der Beitrag, dass dynamische Wettbewerbstheorien sehr wohl zu konkreten wettbewerbspolitischen Empfehlungen führen und einen wichtigen...

We analyze evidence production in merger control as a delegation problem under an inquisitorial and an adversarial competition policy system. Agents' incentives to produce evidence depend critically on the action set of the decision maker. In an inquisitorial system, allowing ex ante for a...
