This study addresses two issues. First, does corporate social performance matter in Hong Kong. Second, if yes, is it relevant to some industries more than others. To answer these questions, we develop a corporate social performance index (CSP) to measure the quality of corporate social performance of major Hong Kong listed firms. The criteria are based on the OECD Principles of Corporate Governance. Using the 3-year period from 2002 to 2005, we find that firm valuation is positive and significantly associated with CSP. Interestingly, this relation matters less in China related firms and firms with a concentrated ownership structure. The results also show that CSP impacts firm valuation more positively when the firm is in the service sector. We further find that CSP is positively related to the market valuation of the subsequent year.
Potential gains from international diversification depend upon the degree of market integration. This paper compares the degree of market integration before and after the stock crash in October 1987 and tests whether the results differ across different investment horizons. Empirical results show that the potential gains from diversification are greatly reduced to an increase in the correlation between stock markets after the stock crash. Our results are robust over different investment horizons.
