Abstract

When financial market collapses, policymakers tend to disclose more public information to traders (e.g., more frequent communication with public) in order to reduce uncertainty surrounding the market and thus revive demand for risky assets. Can such a disclosure policy achieve its objective? In order to address this issue, we augment an exogenous public signal to the model of Angeletos and Werning (2006) and Rondina and Shim (2015) so that both exogenous and endogenous public information coexist. After proving that there exist equilibria in our model economy, we show that provision of more precise exogenous public information to traders in turn can reduce the informativeness of the endogenous public signal (asset price), especially when such a policy is necessary.
