A note on capital market segmentation: new tests and evidence

Abstract

This study applies cointegration tests for a localized form of capital market segmentation. We find evidence of segmentation as well as integration within the same stock exchange. The experimental design for tests of a localized form of capital market segmentation avoids the shortcomings of the capital asset pricing model as well as the need to control for transaction and information costs, and institutional and regulatory differences across financial markets and therefore offers more conclusive results. Moreover, the cointegration test, as contrasted with the conventional t-test of significance of the price premia of foreign shares over local shares, offers a more direct and powerful test of the localized form of market segmentation in this instance. © 1993.
