Entry and consumer welfare in a differentiated Cournot oligopoly

Hoe Sang Chung

Economics Letters, 2023, vol. 231, issue C

Abstract: This study investigates the effect of entry on consumer welfare in a Cournot oligopoly with differentiated products. Considering the entry of a firm that is less efficient than incumbents, I show that in contrast to the case of homogeneous products, entry is detrimental to consumers if the entrant is sufficiently inefficient.
