In many settings where spatial preemption might be expected to produce tightly concentrated industry structures, firms share the market instead. Using a strategic investment model, I show that this can be rationalized by heterogeneous brand preferences, which cause new product introductions by...

This paper introduces a novel method for examining the effects of vertical integration. The basic idea is to estimate the parameters of a vertical entry game. By carefully specifying firms' payoff equations and constructing appropriate tests, it is possible to use estimates on rival profit...

We study how the threat of entry affects service quantity and quality of general practitioners (GPs). We leverage Germany's needs-based primary care planning system, in which the likelihood of new GPs reduces by 20 percentage points when primary care coverage exceeds a cut-off. We compile novel...

This paper adds two elements to a standard model of monopolistic competition: First, the number of potential entrants is limited in each period and increases only over time. Second, the potential entrants differ with respect to the consumers' valuation of the variant they could offer. It is...

There appears to be an ambivalent dimension in innovation strategies: timing. When is an innovation ready for the market or when is the market ready for the innovation? This paper empirically investigates the determinants of a firm?s decision to become a first mover or a follower in innovation...

Do firm entry and exit improve the competitiveness of regions? If so, is this a universal mechanism or is it contingent on the type of industry or region in which creative destruction takes place? This paper analyses the effect of firm entry and exit on the competitiveness of regions, measured...

That is why government, industries, non-profit-organisations, trade unions and consumers would like to come together...
