Abstract

European Union (EU) accession involves both political and economic reforms which suggest changes with regard to financial markets. This study contains empirical tests of four research questions relating to the effects of EU accession. The initial question relates to effects on the level of integration between equity markets in European transition economies and those in global as well as European economies. The second research question explores changes in the level of influence of global and local macroeconomic factors on equity market performance. The last two questions explore the impact of EU accession on equity market volatility and return levels. The study is based on data samples taken from eight markets which accessed the EU in May 2004. The study provides evidence of a significant increase in the level of equity market integration, measured by co-movement between equity indices in transition economies and global reference indices. This implies that while successful market liberalisation involves an increase in the level of co-movement, as is concluded in existing academic research, further equity market co-movement can be expected as a result of EU accession. With regard to the co-movement with European reference indices, the results of the study suggest that increases occur at stages prior to the actual EU accession announcement and that no statistically significant change occurs in association with EU accession. The study also provides evidence suggesting that the influence of macroeconomic factors shifts from local to global factors in association with the EU accession. Global factors demonstrate a significant increase in explanatory power after the
