We study a two-sided market where a platform attracts firms selling differentiated products and buyers interested in those products. In the unique subgame perfect equilibrium of the game, the platform fully internalizes the network externalities present in the market and firms and consumers all...

This paper is the first to examine the effect of minimum price guaranteesin a sequential search model. Minimum price guarantees are notadvertised and only known to consumers when they come to the shop.We show that in such an environment, minimum price guarantees increasethe value of buying the...

Launching and stimulating competition in telecommunications markets is an important policy goal. It contains two elements: to encourage entry and to make competition effective such that consumers benefit. The first one requires that entrants can make profits after investing in infrastructure so...

Trade unions are often argued to cause allocative inefficiencies and to lower welfare. We analyze whether this evaluation is also justified in a Cournot-oligopoly with free but costly entry. If input markets are competitive and output per firm declines with the number of firms (business...

We set up a model to analyze the effects of mergers between sellers of complementary components where firms invest in compatibility and can engage in bundling. We consider the impact of merger on prices, investment and consumer surplus. We also analyse when the merged firm may have an incentive...
