This paper tests a composite empirical model of cross-border acquisitions i
nvolving UK firms between 1987-1995 using panel data analysis. The empirica
l model includes capital market variables and regulatory variables derived
from the existing literature. The results show that models that explain cro
ss-border acquisitions through capital market imperfections are not signifi
cant. Cross-border activity has a strong relationship with the level of the
UK stock market suggesting that cross-border acquisitions are, in some par
t, an extension of domestic activity. Corporate tax differentials also have
significant impact on activity.
