This paper develops a new and easily implementable necessary and sufficient condition for the exact identification of a Markov-switching SVAR model. The theorem applies to models with both linear and some nonlinear restrictions on the structural parameters. We also derive efficient MCMC...

There prevails a view that the monetary policy in the Euro area has changed, especially after the European Monetary System (EMS) came into operation in 1979. The goal of this paper is to quantify (1) the extent to which policy regime has changed and (2) the counterfactual effects of such regimes...

This paper addresses two substantive issues: (1) Does the magnitude of the expectation effect of regime switching in monetary policy depend on a particular policy regime? (2) Under which regime is the expectation effect quantitatively important? Using two canonical DSGE models, we show that...

The literature on the zero lower bound has grown rapidly since Eggertsson and Woodford (2003). But estimation of the effects of practical monetary policy at the zero lower bound (ZLB) remains a daunting task. In this paper, we propose a new approach to estimating a log-linearized DSGE model with...

Markov-switching DSGE (MSDSGE) modeling has become a growing body of literature on economic and policy issues related to structural shifts. This paper develops a general perturbation methodology for constructing high-order approximations to the solutions of MSDSGE models. Our new method, called...

Structural vector autoregressions (SVARs) are widely used for policy analysis and to provide stylized facts for dynamic stochastic general equilibrium (DSGE) models; yet no workable rank conditions to ascertain whether an SVAR is globally identified have been established. Moreover, when...

This paper is about the properties of Markov switching rational expectations (MSRE) models. We present a simple monetary policy model that switches between two regimes with known transition probabilities. The first regime, treated in isolation, has a unique determinate rational expectations...
