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...

In various fields of macroeconomic modelling, researchers often face the problem of decomposing time series into trend component and cycle fluctuations. While there are several potentially useful methods to perform the task in question, Hodrick-Prescott (HP) fi lter seems to have remained...

Many countries have implemented inflation targeting in recent decades. At the same time, the international conditions have been favorable, so it is hard to assess to what extent the success in stabilizing inflation should be attributed to good luck and to what extent to the specific policy...

In modelling of economical time series, it is logical to come out from hypotheses to some economic relationship. If the deviation of time series development is only short time period, with time limit behind it cannot go, we say that time series are in equilibrium. Statisticians call it...

In recent time inflation became a topic between economists and statisticians. An important question is not only an inflation development, but also especially an identification of factors, which influence it. The solution of this task turns into difficult empirical problem not only because of...

The goal of article is to explain the integrated process and stochastic trend like an origin of seeming regression and clarifies a way of detection. The first part contains a description and clarification of stationer and non-stationer attributes of generating process in time series. The second...
