Unfortunately, few existing indices of industrial concentration are based on underlying economic theory, and those that are based on theory are based on models of perfect information. We derive a general performance measure relevant for industries that experience imperfect information. We do so by specifying a social welfare function that reflects the objectives of the policymaker and maps characteristics of industry equilibria under uncertainty into a real number that summarizes industry performance. The importance of explicitly accounting for the information structure of an industry is illustrated by deriving a reduced form for the performance measure valid when a monopolist faces random demand.
