This paper derives alternative measures of the short-run NAIRU (SRN) for the UK, the rate for unemployment at which inflation will neither increase nor decrease in the short-run. We estimate the NAIRU jointly with price equations by using the Kalman filter. Our work suggests that both structural...

We examine the linear-quadratic (LQ) approximation of non-linear stochastic dynamic optimization problems in macroeconomics, in particular for monetary policy. We make four main contributions: first, we draw attention to a general Hamiltonian framework for LQ approximation due to Magill (1977)....

Recent interest in ‘Risk Management’ has highlighted the relevance of Bayesian analysis for robust monetary- policy making. This paper sets out a comprehensive methodology for designing policy rules inspired by such considerations. We design rules that are robust with respect to model...
