This paper considers VAR models incorporating many time series that interact through a few dynamic factors. Several econometric issues are addressed including estimation of the number of dynamic factors and tests for the factor restrictions imposed on the VAR. Structural VAR identification based on timing restrictions, long run restrictions, and restrictions on factor loadings are discussed and...

The purpose of this study is to analyse the dynamic response of a set of euro area macroeconomic variables to monetary policy and technology shocks. We do so by conducting simulations on three different models of the euro area. The first modelling approach corresponds to structural VAR models (SVAR), the second approach uses the NiGEM multi-country model developed by the National Institute of E...

I investigate the convergence of demand and supply shocks in new EU member countries to those of the EU. High synchronization of the shocks would indicate relatively low costs of joining a monetary union. Applying the Kalman filter to demand and supply shocks recovered from SVAR, I calculate time varying coefficients in regression of shocks in individual countries versus the EU. For most countr...

We examine the different effects of monetary policy actions and central bank communication on China's stock market bubbles with a Time-varying Parameter SVAR model. We find that with negative responses of fundamental component and positive responses of bubble component of asset prices, contractionary monetary policy induces the observed stock prices to rise during periods of large bubbles. By c...
