In this paper we estimate a continuous time macro-econometric model of the Czech economy. The model is built as a system of twelve non-linear differential equations. We illustrate how the model can be used to determine the nominal equilibrium exchange rate of the Czech koruna in a macro-economic...

In this paper we estimate a continuous-time macroeconometric model of the Hungarian economy and compare it with the Czech model described in Stavrev (1998). On the basis of the estimated models we provide simulations and compare the results between the two countries for i) anti-inflationary...

Nonparametric unit-root tests are a useful addendum to the tool-box of time-series analysis. They tend to trade off power for enhanced robustness features. We consider combinations of the RURS (seasonal range unit roots) test statistic and a variant of the level-crossings count. This combination...

Tests for relative predictive accuracy have become a widespread addendum to forecast comparisons. Many empirical research reports conclude that the difference between the entertained forecasting models is 'insignificant'. This paper collects arguments that cast doubt on the usefulness of...

The occurrence of decision problems with changing roles of null and alternative hypotheses has increased interest in extending the classical hypothesis testing setup. Particularly, confirmation analysis has been in the focus of some recent contributions in econometrics. We emphasize that...

We extend fixed-b asymptotic theory to the nonparametric Phillips-Perron (PP) unit root tests. We show that the fixed-b limits depend on nuisance parameters in a complicated way. These non-pivotal limits provide an alternative theoretical explanation for the well known finite sample problems of...
