Producers of heterogeneous goods with heterogeneous costs compete in prices. When
producers know their own production costs and the consumer knows their values, consumer
surplus and total surplus are aligned: the information structure and equilibrium that maximize
consumer surplus also maximize total surplus. We report when alignment extends to
the case where either the consumer is uncertain about their own values or producers are
uncertain about their own costs. Less information for either producers or consumer may intensify competition in a way that benefits the consumer but results in inefficient production. We illustrate this within the Hotelling duopoly.
