Does entry improve welfare? A general equilibrium approach to competition policy
We consider a general equilibrium model under imperfect competition. Firms have constantreturns, they are price taker in the input market and compete à la Cournot in theproduct market. We assume a representative consumer exists. We show that an increase inthe number of firms of a given market does not always improve welfare, challenging thecommon idea according to which mergers with no cost synergy are not desirable for theconsumer.
