Merger simulation in competition policy: A survey

Budzinski, Oliver; Ruhmer, Isabel - 2009

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...

A size-based ecosystem model

Ravn-Jonsen, Lars J. - 2009

Ecosystem Management requires models that can link the ecosystem level to the operation level. This link can be created by an ecosystem production model. Because the function of the individual fish in the marine ecosystem, seen in trophic context, is closely related to its size, the model groups...

Horizontal mergers, involuntary unemployment, and welfare

Budzinski, Oliver; Budzinski, Jürgen-Peter - 2009

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...

The stock concept applicability for the economic evaluation of marine ecosystem exploitation

Ravn-Jonsen, Lars J. - 2009

preferred tool for fishery economics since Clark and Munro (1975) introduced capital theory in these models. Ravn-Jonsen (2009c …) applied capital theory to a model in which the production in the ecosystem is a consequence of predator-prey interaction and …

Advertised meeting-the-competition clauses: Collusion instead of price discrimination

Budzinski, Oliver; Kretschmer, Jürgen-Peter - 2010

Pricing strategies may include the advertising of meeting-the-competition clauses (MCCs). We show in a specific spatial model scenario with differently informed consumers that MCCs primarily serve as a device to facilitate collusion instead of allowing for price discrimination between these...
