Uncertainty Traps [PDF]

open access: yesThe Quarterly Journal of Economics, 2014
Abstract We develop a theory of endogenous uncertainty and business cycles in which short-lived shocks can generate long-lasting recessions. In the model, higher uncertainty about fundamentals discourages investment. Since agents learn from the actions of others, information flows slowly in times of low activity and uncertainty remains ...
