Uncertainty Shocks, Learning from Prices and Costly Information Acquisition
A general equilibrium model is presented in which individuals can learn about the realization of a payoff relevant latent random variable at a cost or extract information embedded in prices. While only partially revealing the realization of the latent random variable, equilibrium prices fully reveal realized payoff risk and, when only updated by observation of prices, posterior uncertainty is state-dependent. Equilibrium is constrained efficient
