We estimate the deterrence effects of U.S. merger policy instruments with respect tothe composition and frequency of future merger notifications. Data from the Annual Reports bythe U.S. DOJ and FTC allow industry based measures over the 1986-1999 period of theconditional probabilities for...

We formulate a simple model of optimal defensive disclosure by a monopolist facinguncertain antitrust enforcement and test its implications using unique data on defensivedisclosures and patents by IBM during 1955-1989. Our results indicate that strongerantitrust enforcement leads to more...

Industry-wide voluntary agreements are touted as a means for corporations to take more corporate social responsibility (CSR). We study what type of joint CSR agreement induces firms to increase CSR efforts in a model of oligopolistic competition with differentiated products. Consumers have a...

To stimulate companies to take corporate social responsibility collectively, for example for climate change or fair trade, their agreements may be exempted from cartel law. To qualify under Article 101(3) TFEU, the public benefits must compensate consumers for higher prices of the private good....

This paper analyzes the effect of carrier collaboration on fleet capacity, fleet structures in terms of the number and the size of vehicles, and load factors. The model features complementary networks, scheduling, price elastic demands, and demand uncertainty. For the case of a given number of...

This paper introduces the Werden-Froeb Index (WFI) to assist in evaluating merger-specific efficiencies in horizontal mergers. The index measures the weighted average reduction in marginal costs required to restore pre-merger equilibrium prices and quantities after the (full or partial) merger...

An important question in the dynamic European wholesale markets for electricity is whether to define the geographical market at the level of an individual member state or more broadly. We show that if we currently take the traditional approach by considering for each member state whether there...

In economic environments, decision-makers may strategically delay irreversible investments to learn from the actions of others creating socially suboptimal outcomes. We investigate if and how communication mitigates the strategic delay in investment timings. Players choose when to invest in a...

There is a growing concern that U.S. merger control may have been too lenient, but empirical evidence remains limited. After reviewing event studies as a method to acquire empirical insights into the competitive effects of mergers, I propose a novel application using Hoberg-Phillips TNIC data....

This paper develops a model of the birth and death of cartels in the presence of enforcement activities by a Competition Authority (CA). We distinguish three sets of interventions: (a) detecting, prosecuting and penalizing cartels; (b) actions that aim to stop cartel activity in the short-term,...
