Abstract
This paper investigates the importance of the Balassa-Samuelson effect for two acceding countries (Bulgaria and Romania), two accession countries (Croatia and Turkey) and two CIS countries (Russia and Ukraine). The paper first studies the basic assumptions of the Balassa-Samuelson effect using yearly data, and then undertakes an econometric analysis of the assumptions on the basis of monthly data. The results suggest that for most of the countries, there is either amplification or attenuation, implying that any increase in the open sector's productivity feeds onto changes in the relative price of non-tradables either imperfectly or in an over-proportionate manner. With these results as a background, the size of the Balassa-Samuelson effect is derived. For this purpose, a number of different sectoral classification schemes are used to group sectors into open and closed sectors, which makes a difference for some of the countries. The Balassa-Samuelson effect is found to play only a limited role for inflation and real exchange rate determination, and it seems to be roughly in line with earlier findings for the eight new EU member states of Central and Eastern Europe
