We analyze third degree price discrimination by an upstream monopolist to a continuum of heterogeneous downstream firms. The novelty of our approach is to recognize that customizing prices may be costly. As a consequence, partial price discrimination arises in equilibrium; in particular,we...

We propose a simple model to analyze the widespread idea that a necessary condition for firms to make foreign direct investments is that they have firm-specific advantages with respect to host country firms. We show that no such advantages are necessary to become multinationals. Further, firms...

Das Aufkommen neuer Technologien, die US-Dominanz in der Digitalisierung und insbesondere der Aufstieg Chinas zu einem Konkurrenten stellen die Industrieunternehmen Deutschlands und Europas vor große Herausforderungen. Die Politik, allen voran Deutschland und Frankreich, fordert nun einer...

It has been suggested that mergers, by increasing concentration, raise incentives to invest and hence are pro-competitive. To study the effects of mergers, we rewrite a game with simultaneous price and cost-reducing investment choices as one where firms only choose prices, and make use of...

We propose a simple theory of predatory pricing, based on scale economies and sequential buyers (or markets). The entrant (or prey) needs to reach a critical scale to be successful. The incumbent (or predator) is ready to make losses on earlier buyers so as to deprive the prey of the scale it...

This paper studies a model where exclusive dealing (ED) can both promote investment and foreclose a more efficient supplier. While investment promotion is usually regarded as a pro-competitive effect of ED, our paper shows that it may be the very reason why a contract that forecloses a more...

As a general principle, state aid to firms and sector-specific support schemes should be used only when there are market failures; that is, when there are good reasons to believe that the market would not deliver efficient and/or equitable outcomes.

I show that an advertising ban is more likely to increase - rather than decrease - total consumption when advertising does not bring about a large expansion of market demand at given prices and when it increases product differentiation (thus allowing firms to command higher prices). In this...

We extend the literature on exclusive dealing, which assumes that entry can occur only by installing new capacity, by allowing the incumbent and the potential entrant to merge. This uncovers new effects. First, exclusive deals can be used to improve the incumbent's bargaining position in the...
