Assessing Financial Integration in European Union Equity Markets, 1990-2006: Panel Unit Root And Multivariate Cointegration And Causality Evidence
This paper measures financial integration among selected European Union equity markets over the period July 1990 to June 2006 using daily data. Eleven markets (Austria, Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Netherlands, Spain and the United Kingdom) are included in the analysis. Panel unit root tests are used to test for non-stationarity, and multivariate cointegration, Granger causality and level VAR procedures and variance decompositions are conducted to examine the equilibrium and causal relationships among these markets. The results indicate that there is a stationary long-run equilibrium relationship among, and significant and substantial short and long-run causal linkages between, these markets. The findings offer complementary evidence that a high level of financial integration prevails in the region.
