We show how observed product margins may be used in lieu of an observed market elasticity to calibrate parameters for two commonly used demand forms: the Almost Ideal Demand System (AIDS) and the multinomial logit. This technique is useful for antitrust practitioners interested in simulating the...

In most jurisdictions, antitrust fines are based on affected commerce rather than on collusive profits, and in some others, caps on fines are introduced based on total firm sales rather than on affected commerce. We uncover a number of distortions that these policies generate, propose simple...

The EU Leniency Programme (LP) aims to encourage the dissolution of existing cartels and the deterrence of future cartels, through spontaneous reporting and/or significant cooperation by cartel members during an investigation. However, the European Commission guidelines are rather vague in terms...

Over the last decade a large body of economic research has emerged that has sought to empirically test the effectiveness of leniency policies as tools to enhance the detection, prosecution and deterrence of cartel conduct. This research has considerable potential value in assisting competition...

The theoretical framework of the adequacy or otherwise of fine reductions under the EU and US Leniency Programmes has been explored widely. However, the characteristics of the reporting cartel members remain unexplained. This is the first paper to develop a model where heterogeneous cartel...

Cartels remain widespread and constitute a major problem for society. Leniency policies reduce or cancel the sanctions for the first firm(s) that self-report being part of a cartel and have become the main enforcement instrument used by competition authorities around the world in their fight...

An antitrust authority deters collusion using fines and a leniency program. It chooses the probability of an investigation. Firms pick the degree of collusion: The more they collude, the higher are profits, but so is the probability of detection. Firms thus trade-off higher profits against...

New Zealand is a small open economy that is remote from all major markets. The smallness and remoteness of New Zealand combine to imply that this country has, at least quantitatively, distinctive features for the regulation of economic activity by competition law. The isolation and small size of...

By replicating Articles 85 and 86 of the EC Treaty the Danish Competition Act (put in force January 1998) constituted a shift from the control principle to the prohibition principle. This is an important improvement from the point of view that regulatory legislation should be designed to give...

This article investigates the nexus of competition and stability in European banking. It analyzes the European legal framework for competition policy in banking and several cases that pertain to anti-cartel policy, merger policy, and state-aid control. It discusses whether and how competition...
