| Abstract: | The author examines the implications of the presence of multiproduct firms for cartel stability in a horizontally differentiated market. Under quantity competition, an increase in the number of varieties produced by each firm, for any given numer of companies, increases the critical discount factor above which collusion is sustainable by trigger strategies, and thus makes collusion less likely. |
