Inflation in New EU Member States: A Domestically or Externally Driven Phenomenon?

ABSTRACT This article empirically analyzes the domestic and external inflation determinants for eight non-eurozone new EU member states (NMS), using a structural vector autoregression model. Results indicate that foreign shocks are a major factor in explaining inflation dynamics in the medium run, while the short-run inflation dynamics are mainly influenced by domestic shocks. Moreover, the importance of the foreign inflation component has had a rising trend in the precrisis period in all NMS and mostly coincided with their accession to the EU. This trend ended with the onset of the global financial crisis. The study implicates the need to augment the classical Taylor rule with foreign factors in the case of small open economies.

Public debt and economic growth conundrum: nonlinearity and inter-temporal relationship

Abstract The influential paper by Reinhart and Rogoff (Reinhart, C. M., and K. S. Rogoff. 2010. “Growth in a Time of Debt.” The American Economic Review 100: 573–578.) has triggered a debate about the effects of the public debt on GDP growth. They argue that a debt-to-GDP ratio of over 90 percent has a deleterious effect on long-run economic growth. In this paper, we examine the inter-temporal relationship between public debt and GDP growth rates. We examine debt-to-GDP thresholds in nonlinear panel models, using various econometric strategies, methodologies, and data samples. We also evaluate confidence intervals around the estimated thresholds to determine the accuracy of estimated thresholds. Our results demonstrate that in the majority of estimated models, threshold values are not uniquely defined and the estimated coefficients are insignificant in most model specifications, as in Enders, Falk, and Siklos (Enders, W., B. L. Falk, and P. Siklos. 2007. “A Threshold Model of Real US GDP and the Problem of Constructing Confidence Intervals in TAR Models.” Studies in Nonlinear Dynamics & Econometrics 11: 1322.). Next, we examine the inter-temporal relationship between the public debt and economic growth using structural panel data models as well as reduced form panel VAR models. In contrast to the standard presumption in the literature, we find that the inter-temporal effect of economic growth on the public debt is strong, but the effect of the public debt on economic growth is weak. We find similar results in sub-samples that include countries where the public debt is over 90 percent of GDP.

Technology, employment and the business cycle in post-transition countries of the EU

Abstract This article analyses the importance of technology and non-technology shocks in the business cycles of European Union post-transition countries. Different assumptions of New Keynesian and Real Business Cycle theory are tested. The results demonstrate that a non-technology shock is more important in explaining business cycles in post-transition countries, although a technology shock is not trivial. The technology shock cannot replicate basic business cycle facts observed in the data: it produces a low or negative correlation between employment and GDP, and a strong negative correlation between labour productivity and employment. Technology and non-technology GDP components are analysed in the transition and post-transition period. The results show a non-technology shock was the dominant source of business cycles both during and after the transition period.
