New-Keynesian model of inflation and its empirical verification

New concepts have been presented in modelling of inflation dynamics recently, among others the New Keynesian Phillips curve (NKPC). There are several traditional ways of NKPC model validity testing, but none of them seems to be practically applicable in conditions of the Czech Republic. We tried to test the validity of the NKPC model by the untraditional method proposed by Demery and Duck (2002). This method does not rely on direct estimation of NKPC parameters, but relatively easy tests based on the cointegration analysis of time series are employed. Its application indicates that the NKPC model cannot be considered as effective in conditions of the Czech Republic; this model does not describe the inflation process sufficiently and it is not a suitable model for inflation prediction or for the choice of appropriate monetary (anti-inflation) policy.
