Abstract

Two one-product firms compete inprices on a market with differentiated products. Goods are differentiated because customers switch from one good to the other at different relative prices. With the spectification that mean demand in the market is unit-elastic I provide conditions on the shpe of the customer density which guarantee the existence of a unique Bertrand equilibrium.
