We show that, when unit costs of quality are increasing and quadratic, each  rm has an incentive to provide an interval of qualities. The  nding is in sharp contrast to the single-quality outcome when the market cover- age is exogenously determined. We also show that allowing for an interval of qualities intensi es competition, lowers the pro ts of each  rm and raises the consumer surplus and the social welfare in comparison to the single-quality duopoly.","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Subsequently published in B.
