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...

Standard welfare analysis of horizontal mergers usually refers to two effects: the anticompetitive market power effect reduces welfare by enabling firms to charge prices above marginal costs, whereas the procompetitive efficiency effect increases welfare by reducing the costs of production...

Despite still being younger than a decade, the theory of multisided market has offered numerous valuable insights for the analysis of non-ordinary industries in which a supplier serves two distinct customer groups that are indirectly interrelated by externalities. Examples include payment...

Naturally, competition policy is based on competition economics made applicable in terms of law and its enforcement. Within the different branches of competition economics, modern industrial economics, or more precisely game-theoretic oligopoly theory, has become the dominating paradigm both in...

This paper provides a comparative analysis of methods for the empirical ex post evaluation of merger control decisions. It develops a competition-policy oriented framework of assessment criteria for the leading evaluation methods and applies them to structural modeling and simulation,...

Newspapers have experienced declining circulation figures and declining advertising revenues for several years. In particular, declining advertising figures put a threat on newspapers – this is especially severe in the US where 73% of their revenues are generated through advertising. On the...

Newspapers have been experiencing declining circulation figures and diminishing advertising revenues for several years – both effects might pose a threat to the continuing existence of (print) newspapers. In an earlier paper, Lindstädt & Budzinski (2011) argued from a theoretical viewpoint...
