Public and Private Information in Monetary Policy Models

  • Jeffery D. Amato
  • Hyun Song Shin

This paper examines the impact of public information in an economy where agents also have diverse private information. Since disclosures by central banks are an important source of public information, we are able to assess how the words of central bankers shape expectations, in addition to their actions. In an otherwise standard macro model, the disproportionate role of public information degrades the information value of economic outcomes, alters the welfare consequences of increased precision of public information and generates distinctive time series characteristics of some macro variables.
