This paper investigates whether the presence of financial frictions can help explain the differences in the variability of output and inflation between the Pre- and the Post-Volcker periods. I use a limited participation model with credit market imperfections, in which financial frictions may...

Various approaches to optimal monetary policy have been used to select time-invariant policy rules, including the timeless perspective approach by Woodford (1999) and the unconditional expected utility criterion of McCallum (2000). In this paper, we argue instead that policy rules should be...

This paper surveys the economic literature on simple policy rules and analyzes econometric methods used to estimate them, emphasizing effects of model misspecification. We draw attention to inconsistencies in evaluation of the rules and implications for policy advice, which is commonly done...

There is substantial evidence suggesting that central banks in open economies react to exchange rate fluctuations in addition to expected inflation and output. In some developing countries this reaction is comparatively larger and it is nonlinear. Using an estimated structural macromodel, this...

This paper evaluates monetary policy rules in a business cycle model with staggered prices and wage setting a la Calvo and asymmetric information in the credit market. Rules are compared in a utility based welfare metric, the effects of the model’s nonlinear dynamics are captured by a...
