Abstract

We study the effect of releasing public information about productivity or monetary shocks when agents learn from nominal prices. While public releases have the benefit of providing new information, they can have the cost of reducing the informational efficiency of the price system. We show that, when agents have private information about monetary shocks, the cost can dominate, in that public releases increase uncertainty about fundamentals. In some cases, public releases can create or eliminate multiple equilibria. Our results are robust to adding velocity shocks, imperfectly observable prices, large idiosyncratic shocks, and introducing a bond market.
