We study how the use of judgment or "add-factors" in forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in a standard self-referential environment....

This paper revisits the issue of money growth versus the interest rate as the instrument of monetary policy. Using a dynamic stochastic general equilibrium framework, we examine the effects of alternative monetary policy rules on inflation persistence, the information content of monetary data,...

We study how the use of judgment or "add-factors" in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We examine the possibility of a new phenomenon, which we call exuberance equilibria, in the New Keynesian monetary policy...

We use a general equilibrium finance model that features explicit government purchases of private debts to shed light on some of the principal working mechanisms of the Federal Reserve’s large-scale asset purchases (LSAP) and their macroeconomic effects. Our model predicts that unless private...

We study how the use of judgement or "add-factors" in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in standard macroeconomic...

When monetary policies are endogenous, the conventional VAR approach for detecting the effect of monetary policies is powerless. This paper proposes to test the implication of monetary policies along a different dimension. That implication is to exploit the policy induced exogeneity of...

This paper shows that the optimal monetary policies recommended by New Keynesian models still imply a large amount of inflation risk. We calculate the term structure of inflation uncertainty in New Keynesian models when the monetary authority adopts the optimal policy. When the monetary policy...

This paper proposes a solution method to solve linear difference models with lagged expectations. Variables with lagged expectations expand the model's state space greatly when N is large; and getting the system into a canonical form solvable by the traditional methods involves substantial manual...

This paper develops a monetary model with taxes to account for the apparently asymmetric and time-varying effects of energy shocks on output and hours worked in post-World War II U.S. data. In our model, the real effects of an energy shock are amplified when the monetary authority responds to...

This article presents global solutions to standard New Keynesian models to show how economic dynamics change when the nominal interest rate is constrained at its zero lower bound (ZLB). We focus on the canonical New Keynesian model without capital, but we also study the model with capital, with...
