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 … information. Models differ in their motives for information acquisition and the cost of information, or learning technology …

We survey the recent literature on learning in financial markets. Our main theme is that many financial market … uncertain and subject to learning. We discuss phenomena related to the volatility and predictability of asset returns, stock …

Learning or experience curves are widely used to estimate cost functions in manufacturing modeling. They have recently … shows that there is a fundamental statistical identification problem in trying to separate learning from exogenous … technological change and that the estimated learning coefficient will generally be biased upwards. Second, we present two empirical …

We study the perfect Bayesian equilibrium of a model of learning over a general social network.
