Resumen de Is Monetary Policy in New Members States Asymmetric?
Estimated Taylor rules became popular as a description of monetary policy conduct. There are numerous reasons why real monetary policy can be asymmetric and estimated Taylor rule nonlinear. This paper tests whether monetary policy can be described as asymmetric in three new European Union (EU) members (the Czech Republic, Hungary and Poland), which apply an inflation targeting regime. Two different empirical frameworks are used: (i) a Generalized Method of Moments (GMM) estimation of models that allow discrimination between the sources of potential policy asymmetry but are conditioned by specific underlying relations (Dolado et al., 2004, 2005; Surico, 2007a,b); and (ii) a flexible framework of sample splitting where nonlinearity enters via a threshold variable and monetary policy is allowed to switch between regimes (Hansen, 2000; Caner and Hansen, 2004). We find generally little evidence for asymmetric policy driven by nonlinearities in economic systems, some evidence for asymmetric preferences and some interesting evidence on policy switches driven by the intensity of financial distress in the economy.
