Secret information acquisition in Cournot markets
AbstractTwo-stage game models of information acquisition in stochastic oligopolies require the unrealistic assumption that firms observe the precision of information chosen by their competitors before determining quantities. This paper analyzes secret information acquisition as a one-stage game. Relative to the two-stage game firms are shown to acquire less information. Policy implications based on the two-stage game yield, therefore, too high taxes or too low subsidies for research activities. For the case of heterogeneous duopoly it is shown that comparative statics results partly depend on the observability assumption.
