No, not really. Responding to lingering concerns about the reliability of SVARs, Christiano et al (NBER Macro Annual, 2006, "CEV") propose to combine OLS estimates of a VAR with a spectral estimate of long-run variance. In principle, this could help alleviate specification problems of SVARs in...

Monetary policy is most effective when public beliefs about future policies are actively managed. This is the appeal of policy rules and commitment strategies, typically absent under discretion. But when a policymaker has some private information - as is the case in reality - belief management...

Modeling interest rates over samples that include the Great Recession requires taking stock of the effective lower bound (ELB) on nominal interest rates. We propose a flexible time– series approach which includes a “shadow rate”—a notional rate that is less than the ELB during the period...

In models of monetary policy, discretionary policymaking often lacks the ability to manage public beliefs, which explains the theoretical appeal of policy rules and commitment strategies. But as shown in this paper, when a policymaker possesses private information, belief management becomes an...

No, not really, since spectral estimators suffer from small sample and misspecification biases just as VARs do. Spectral estimators are no panacea for implementing long-run restrictions. In addition, when combining VAR coefficients with non-parametric estimates of the spectral density, care...
