Does the Quality of Corporate Governance Affect Firm Valuation and Risk? Evidence from a Corporate Governance Scorecard in Hong Kong*

Using Hong Kong firm data, we construct an index of corporate governance during 2002–2005, which scores the corporate governance practices of listed companies from the public shareholders' perspective based on the Organization for Economic Corporation and Development Principles of Corporate Governance. The findings show that family firms and firms with concentrated ownership structures are associated with bad corporate governance. The evidence also shows that these firms improve their corporate governance practices slower than their peers. Overall, the quality of corporate governance is very significant in explaining future company stock returns and risk. Good corporate governance is associated with both higher stock returns and with lower risk. Improvements in corporate governance are associated with significantly higher stock returns and lower company risk.     

A CONCEPTUAL FRAMEWORK FOR CORPORATE RISK DISCLOSURE EMERGING FROM THE AGENDA FOR CORPORATE GOVERNANCE REFORM

During the last decade an implicit conceptual framework for internal control and corporate risk management has arisen from risk management practice and policy within UK companies. An explicit conceptual framework for risk management is now emerging and is expressed in the Turnbull Report. In this paper, we develop a diagrammatic representation for the conceptual framework for internal control, risk management and risk disclosure. We consider the recent practical and policy developments in the disclosure of risk-related information in order to establish the current state of the art of corporate risk disclosure. Thus, we focus only on the disclosure aspect of the conceptual framework for internal control. We use a questionnaire survey to canvas the attitudes of UK institutional investors towards risk disclosure in relation to their portfolio investment decisions. Our empirical findings indicate that institutional investors do not generally favour a regulated environment for corporate risk disclosure or a general statement of business risk. The respondents agree that increased risk disclosure would help them in their portfolio investment decisions. However, for other aspects of the risk disclosure issue they are more neutral in attitude. Further, we found that the variation in the attitudes of institutional investors appears to be associated with the characteristics of the funds they manage as well as with their investment horizons. Further, we find that institutional investors’ perceptions of corporate governance are related to their investment horizons, among other factors.     

From T-Bills to Common Stocks: Investigating the Generality of Intra-Week Return Seasonality

The authors investigate the extent to which intra-week seasonality still exists and whether its pattern is uniform across three stock indices and Treasury bonds with seven different maturities. They find that intra-week seasonality continues to be significant and that its pattern is not uniform, either between the stock indices and the Treasury bonds or even among the bonds alone. A pattern shared by stocks and bonds is that Monday returns become increasingly negative with maturity. These findings suggest that neither institutional nor general-equilibriumex planations by themselves can explain the pattern of intra-week seasonality in securities markets.     

Spot and Futures Prices and the Law of One Price

The law of one price (LOP) is tested for narrowly defined commodities traded in futures markets in different countries during the period 1973–80. Although the LOP holds as an average tendency for most of the commodities, there are instances of large riskless arbitrage returns (before transactions costs). Deviations from the LOP tend to be commodity specific rather than due to a common external factor and they tend to be smaller the longer the maturity of the futures contract.
