This paper analyses the incentives to upgrade input quality in vertically related (network) industries. Upstream investments have a biased effect on the downstream companies and lead to vertical product differentiation. Different vertical structures such as vertical integration, ownership and...

This article finds that non-controlling minority shareholdings among competitors lower the sustainability of collusion. This is the case under an even greater variety of situations than was indicated by earlier literature. The collusion destabilizing effect of minority shareholdings is mainly...

Advanced economic instruments like simulation models are enjoying an increased popularity in practical antitrust. There is hope that they being quantitative predictive economic evidence can substitute for qualitative structural analysis and lead to unambiguous results. This paper demonstrates...

Advances in competition economics as well as in computational and empirical methods have offered the scope for the employment of merger simulation models in merger control procedures during the past almost 15 years. Merger simulation is, nevertheless, still a very young and innovative instrument...

Competition law compliance has become increasingly important in the banking industry as the number of infringements and the associated fines imposed by the European Commission are rising. This article shows that not only governments and regulators, but also shareholders and managers, should be...

This paper provides a theoretic model for the analysis of cartel formation in an industry that is subject to profit shocks. The competitive or collusive conduct of a firm is determined by a decision maker who maximizes the present value of utility that accrues to him by earning a share of the...

Although both in US antitrust and European competition law there is a clear evolution to a much broader application of rule of reason (instead of per-se rules), there is also an increasing awareness of the problems of a case-by-case approach. The error costs approach (minimizing the sum of...

The US Supreme Court's overruling of the pre-existing per se illegality of resale price maintenance and the recommendation of a rule of reason approach in the Leegin decision (2007), raise the question whether other jurisdictions should follow this approach and what future assessments of resale...

Regression methods are commonly used in competition lawsuits for, e.g., determining overcharges in pricefixing cases. Technical evaluations of these methods' pros and cons are not necessarily intuitive. Appraisals that are based on case studies are descriptive but need not be universally valid....

In competition law, the problem of the optimal design of institutional and procedural rules concerns assessment processes of the pro- and anticompetitiveness of business behaviors. This is well recognized in the discussion about the relative merits of different assessment principles such as the...
