Competition in some product markets takes the form of a contest. If some firms cooperate in such markets, they must decide how to allocate effort on each of their products and whether to reduce the number of their products in the competition. We show how this decision depends on the convexity...

Merged firms are typically rather complex organizations. Accordingly, me rger has a more profound effect on the structure of a market than simply reducing the number of competitors. We show that this may render horizontal mergers profitable and welfare – improving even if costs are linear. The...

We analyze the incidence and welfare effects of unit sales taxes in experimental monopoly and Bertrand markets. We find, in line with economic theory, that firms with no market power are able to shift a high share of a tax burden on to consumers, independent of whether buyers are automated or...

We analyze the incidence and welfare effects of unit sales tax increases in experimental monopoly and Bertrand markets. We find, in line with economic theory, that firms with no market power are able to shift a high share of the tax burden to consumers, independent of whether buyers are...

We study the merger paradox, a relative of Harsanyi's bargaining paradox, in an experiment. We examine bilateral mergers in experimental Cournot markets with initially three or four firms. Standard Cournot-Nash equilibrium predicts total outputs well. However, merged firms produce significantly...

To be represented by more than one contestant in a contest has advantages and disadvantages. This paper determines the conditions under which it is favorable to send several agents into the contest.

Competition in some markets is a contest. This paper studies the merger incentives in such markets. Merger can be profitable. The profitability depends on the post-merger contest structure, the discriminatory power of the contest and on the number of contestants.

We propose a model in which mergers exert a more pronounced effect on the structure of a market than simply reducing the number of competitors. We show that this may render horizontal mergers profitable and welfare-improving even if costs are linear. The results help to reconcile theory with...
