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...

"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...

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...

Monetary policy VARs typically presume stability of the long-run outcomes. We introduce the possibility of switches in the long-run equilibrium in a cointegrated VAR by allowing both the covariance matrix and weighting matrix in the error-correction term to switch. We find that monetary policy...

This paper uncovers Taylor rules from estimated monetary policy reactions using a structural VAR on U.S. data from 1959 to 2009. These Taylor rules reveal the dynamic nature of policy responses to different structural shocks. We find that U.S. monetary policy has been far more responsive over...
