We demonstrate the possibility of shake-out of firms and emergence of inter-firm heterogeneity along the (socially optimal) dynamic equilibrium path of a competitive industry with free entry and exit, even when there is no uncertainty and all firms are ex ante identical with perfect foresight....

Firms signal high quality through high prices even if the market structure is highly competitive and price competition is severe. In a symmetric Bertrand oligopoly where products may differ only in their quality, production cost is increasing in quality and the quality of each firm’s product...
