Bayesian learning

Isaac Baley () and Laura Veldkamp

Economics Working Papers from Department of Economics and Business, Universitat Pompeu Fabra

Abstract: We survey work using Bayesian learning in macroeconomics, highlighting common themes and new directions. First, we present many of the common types of learning problems agents face-signal extraction problems-and trace out their effects on macro aggregates, in different strategic settings. Then we review different perspectives on how agents get their information. Models differ in their motives for information acquisition and the cost of information, or learning technology. Finally, we survey the growing literature on the data economy, where economic activity generates data and the information in data feeds back to affect economic activity
