Abstract

We propose a unified framework bridging the gap between team and competition issues, in order to reconsider the social value of private and public information in price and quantity games under imperfect and dispersed information, and to compare the corresponding outcomes in terms of equilibrium and social welfare. The informational distortion associated with the competition motive may lead to a negative social value of private information and reverse the perfect information result in favor of strategic substitutability as the source of higher profit and social welfare.
