The paper provides a comprehensive survey of the economics behind the fight against hard core cartels. Differentiating between four subsequent stages – characterisation, welfare effects, enforcement and evaluation – the paper pays particular attention to cartel detection methods, the...

We compare the short-run welfare effects of two types of settlement agreements, quot;reverse paymentsquot; of the brand-name drug makers to generic producers not to enter the market and delayed entry when these payments are restricted both under the entry injunction (imposed by the Hatch-Waxman...

This Article advances a novel theoretical model for assessing policy interventions against Facebook. As prosecutors barrel forward against digital platforms, soon it will fall upon courts and, eventually, regulators to devise remedies. We argue that any sensible solution must include...

A reform movement is underway in antitrust. Citing prior enforcement failures, deviations from the original intent of the antitrust laws, and overall rising levels of sector concentration, some are seeking to fundamentally alter or altogether replace the current consumer welfare standard, which...

In antitrust enforcement as in cost-benefit analysis, neoclassical economics may be interpreted as arguing for the use of a quot;total welfarequot; standard whose implementation treats transfers as welfare-neutral. Several recent papers call for antitrust agencies to move in the direction of...

In this paper we set out the welfare economics based case for imposing cartel penalties on the cartel overcharge rather than on the more conventional bases of revenue or profits (illegal gains). To do this we undertake a systematic comparison of a penalty based on the cartel overcharge with...

In this comprehensive review of ex-post merger studies price effects of horizontal transactions are evaluated. By combining and further analyzing the results of 52 retrospective studies on 82 mergers or merger-like transactions it can be shown that the industry alone is no strong indication for...

Since the publication of Robert Bork's The Antitrust Paradox, lawyers, judges, and many economists have defended “Consumer welfare” (CW) as a standard for decisions about antitrust goals and enforcement priorities. This paper argues that the CW is actually an empty concept and is an...
