We present a new model of multi-product firms (MPFs) and flexible manufacturing and explore its implications in partial and general equilibrium. International trade integration affects the scale and scope of MPFs through a competition effect and a demand effect. We demonstrate how MPFs adjust in...

This paper presents a model of the interaction between two rival firms based in the same country. Each firm must decide how to serve a foreign market (export or foreign production) and how much to invest in a corporate-wide asset that reduces production costs and/or augments the...

We introduce the concept of cooperative substitutes and complements, and use it to throw light on the conditions for a research joint venture to choose equal levels of R&D by all member firms. We show that the second-order conditions for a symmetric optimum take a particularly simple form,...

We analyze a drastic price increase in the German auction market for reserve power, which did not appear to be driven by increased costs. Studying the market structure and individual bidding strategies, we find evidence for collusive behavior in an environment with repeated auctions, pivotal...

Industrial organization is mainly concerned with the behavior of large firms. Experimental industrial organization therefore faces a problem: How can firms be brought into the laboratory? The main approach relies on framing: Call individuals firms! This experimental approach is not in line with...

This paper shows how market entry into an unprofitable market can be profitable for a firm. A firm's expansion into a new market can have a beneficial feedback effect for that firm in its old market. By entering into a new market, the firm increases its produced quantity and has higher...

This paper focuses on incentives to invest in research and development (R&D) in vertically related markets. In a bilateral duopoly setup, we consider how process R&D incentives of the firms in both upstream and downstream market depend on the intensity of simultaneous interbrand and intrabrand...

The existing literature on two-sided markets addresses partici- pation externalities, but so far it has neglected pecuniary externalities between competing platforms. In this paper we build a model that incorporates both externalities. In our setup differentiated platforms compete in advertising...

Both mergers and innovation are central elements of a firm's competitive strategy. However, model-theoretical analysis of the merger-innovation link is sparse. The aim of this paper is to analyze the impact of mergers on innovative activities and product market competition in the context of...

Foreign bank entry is frequently associated with spillover effects for local banks and increasing competition in the local banking market. We study the impact of these effects on host countries. In particular, we ask how these effects interact and how they depend on the competitive environment...
