Standard models of the new trade and location theories usually assume full employment and are thus ill-equipped to study spatial unemployment differences, which in reality are more pronounced that income disparities. Regional labour market theories like the ´wage curve´-approach on the other...

The need for management of the marine ecosystem using a broad perspective has been recommended under a variety of names. This paper uses the term Ecosystem Management, which is seen as a convergence between the ecological idea of an organisational hierarchy and the idea of strategic planning...

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...

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...

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...

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...
