Abstract

We focus on two-player, two-armed bandit games. We analyze the joint effect on the informational spillovers between the players of the correlation between the risky arms, and the extent to which one's experimentation results are publicly disclosed. Our main results only depend on whethert informational shocks bring good or bad news. In the latter case, there is a sense in which the marginal value of these informational spillovers is zero.
