We identify financial stress regimes using a model that explicitly links financial variables with the macroeconomy. The financial stress regimes are identified using a large unbalanced panel of financial variables with an embedded method for variable selection and, empirically, are strongly...

In the wake of the Great Recession, the Federal Reserve lowered the federal funds rate target essentially to zero and resorted to unconventional monetary policy. With the nominal FFR constrained by the zero lower bound (ZLB) for an extended period, empirical monetary models cannot be estimated...

We show that recently developed estimators have very different implications for the impact of jumps on exchange rate...

We study this question in a relatively simple dynamic stochastic general equilibrium model in which crises are endogenous events induced by the presence of...

We include learning in a standard equilibrium business cycle model with explicit growth. We use the model to study how the economy's agents could learn in real time about the important trend-changing events of the postwar era in the U.S., such as the productivity slowdown, increased labor force...
