Abstract
This article studies how the correlation of players’ private information affects their strategic be haviour. We introduce information correlation into a static two-player strategic substitutes entry game. The degree of information correlation is measured by the correlation coefficient of a symmetric joint normal distribution, which is used to model players’ prior distribution. It is found that a cutoff strategy cannot be used for all values of correlation coefficient to solve the game, and there exists a threshold correlation coefficient value to differentiate the unique-equilibrium and the multiple (three)-equilibria situations, given other parameters. Finally, by comparative statics analysis of symmetric equilibrium strategies, we find that increasing the payoff of entry encourages players to adopt a lower entry threshold, while increasing the information correlation or jointly increasing the variances of prior distribution increases the positive entry threshold and lowers the negative entry threshold.

The explosion of information and research that has taken place in recent years has had a profound effect upon a variety of existing academic disciplines giving rise to the dissolution of barriers between some, mergers between others, and the creation of entirely new fields of enquiry.
