This paper explores why competing firms can choose to outsource to an external common supplier that does not have a cost advantage in input production. The supplier, through its contract offers, manages to generate asymmetry, to alter product market competition, and to extract profits from the...

Corporate bankruptcy in Germany has been on a long-run decline. Even before the recent double crisis of the pandemic and multiple cost shocks, bankruptcy figures were one-third lower than around the turn of the century but were larger and affected more mature firms. With the onset of the double...

We present a general and tractable oligopoly model of multi-sided platforms with endogenous side and platform choices of heterogeneous end-users, considering any mix of single-homing and multi-homing platforms and in which participating on one side could preclude doing so on others. We show the...

This paper brings to the forefront the assumptions that we make when focusing on a particular type of explanation for bank profitability. We evaluate a broad field of research by introducing a general framework for a profit maximizing bank and demonstrate how different types of models can be...

The paper shows that taking inventory control out of the hands of competitive or exclusive retailers and assigning it to a manufacturer increases the value of a supply chain especially for goods whose demand is highly volatile. This is because doing so solves incentive distortions that arise...

Im vorliegenden Bericht werden die Ergebnisse des Teilprojektes "Lokale Strategien für die wirtschaftliche Entwicklung" des europäischen Forschungsprojekts TRUSTEE ("Towards RUral Synergies and Trade-offs between Economic development and Ecosystem services') beschrieben. Vor dem Hintergrund...

The increasing role of services in GDP results from the growing share of service industries, but also from the fact that firms produce services along with goods. This paper investigates the determinants of service provision by manufacturing firms. First, it develops a model of differentiated...

This paper analyses the effects of minimum wages on competition in the German roofing sector. The case is particularly interesting since this sector is faced with a uniform minimum wage despite significant regional disparities in productivity and wages. As a control industry we take the plumbing...

This paper studies imperfect price competition between two intermediaries in an electronic business-to-business matching market with indirect network externalities. The intermediaries differ with regard to their ownership structure: an independent third party incumbent marketplace competeswith a...

We consider a mean-field model of firms competing à la Cournot on a commodity market, where the commodity price is given in terms of a power inverse demand function of the industry-aggregate production. Investment is irreversible and production capacity depreciates at a constant rate....
