An increasingly popular approach to policy evaluation involves applying the parameters calibrated for a real business cycle model that does not include policy to a different model, where policy does affect private decisions. This technique, in effect, estimates a model that misspecifies how...

The authors present a theoretical and empirical framework for computing and evaluating linear projections conditional on hypothetical paths of monetary policy. A modest policy intervention does not significantly shift agents' beliefs about policy regime and does not induce the changes in...

Monetary policy analysts looking for a model on which to base decisions may consider two popular approaches-the New Keynesian (NK) and the identified vector autoregression (VAR) approaches. Choosing between the two can be difficult: NK models are stylized and have simple rules while structural...

This paper demonstrates several strengths and shortcomings of models of sectoral reallocation. Although such models demonstrate that sectoral reallocation can be an important amplification and propagation mechanism for exogenous shocks, they are essentially unable to explain any effects of...
