This paper studies the effects of introducing competition for local passenger railway markets in the German state of Baden-Württemberg. We compare the evolution of the frequency of service on lines that were exposed to competition for the market with lines procured by direct negotiations with...

We examine vertical backward integration in oligopoly. Analysing a standard linear Cournot model, we find that for wide parameter ranges (i) some firms integrate, while others remain separated, and (ii) efficient firms are more likely to integrate vertically. Adopting a reduced-form approach, we...

We develop a product market theory that explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each other’s trained employees and finally engage in imperfect product...

In Germany, competitive franchising is increasingly being used to procure passenger railway services that were previously provided by a state monopolist. This paper analyzes 77 tenders that differ with respect to network size, service frequency, contract duration and the proximity to other lines...

We present a new approach to endogenizing technological spillovers. Firms choose levels of a cost-reducing innovation from a continuum before they engage in competition for each other's R&D-employees. Successful bids for the competitor's employee then result in higher levels of cost reduction....

Using a general two-stage framework, this paper gives sufficient conditions for increasing competition to have negative or positive effects on R&D-investment, respectively. Both possibilities arise in plausible situations, even if one uses relatively narrow definitions of increasing competition....
