THE OPERATING BETA OF A U.S. MULTI-ACTIVITY FIRM: AN EMPIRICAL INVESTIGATION

Various researchers have decomposed the firm's beta (or systematic risk) into components that are reflective of the firm's corporate characteristics, for example, leverage position, product mix, etc. In this paper, the theoretical beta decompositions of Hamada (1969 and 1972) and Rubinstein (1973) are sub- jected to empirical examination for a sample of diversified (or multi-activity) firms. The results of the analysis evidence highly significant empirical support for the Hamada- Rubinstein model and for the viability of operationalizing that model with available accounting and market data.     

AN EMPIRICAL INVESTIGATION INTO THE IMPACT OF PROFIT SHARING SCHEMES OF EXECUTIVIES ON THE CONTENT OF CORPORATE SUBMISSIONS ON PROPOSED ACCOUNTING STANDARDS

This paper examines the comments submitted by UK companies on 20 proposed accounting standards to test the hypotheses that executives favor standards that increase, or dampen the variance of, accounting profit numbers on which their incentive remuneration is based. Test results were generally as hypothesised but only the profit variance outcomes were statistically significant. Allowing for political environment changes affected only the profit variance results. There was no evidence that the relative monetary size of bonus payments was a significant lobbying factor. No significant differences were found between the lobbying preferences of companies with or without executive incentive schemes.     

INTERRELATIONSHIPS AMONG DOMESTIC AND EUROCURRENCY DEPOSIT YIELDS: A FOCUS ON THE U.S. DOLLAR

The effectiveness of monetary and fiscal policy actions is partially dependent upon the degree of isolationism of the U.S. money markets. This paper extends the study of capital market integration by investigating the relationships between yields on various currency denominated deposits. The only identified impact of changes in U.S. dollar yields, at home or abroad, on other currency returns is through contemporaneous determination; no direct causality from U.S. to foreign yields is indicated. Several significant reverse causality relationships, however, are evident.     

THE IMPACT OF U.S. REQUIREMENTS FOR AUDIT COMMITTEES ON THE STRUCTURE AND MEMBERSHIP OF NON-U.S. AUDIT COMMITTEES

Many non-U.S. national stock exchanges have amended their listing standards to require audit committees during the last two decades, while U.S. national stock exchanges have recently amended their listing standards in response to recommendations made by the Blue Ribbon Committee on Improving the Effectiveness of Corporate Audit Committees (BRC). These new listing requirements for U.S. registrants (SEC Form 10-K filers) provide an opportunity to contrast and examine requirements for audit committee structure and membership of non-U.S. registrants (SEC Form 20-F filers). Recognizing that the International Accounting Standards Board has identified a “core” set of basic accounting standards in international filings accentuates the need to have uniform requirements for audit committees. This paper argues that requirements for audit committees should be consistent to improve financial reporting in a global securities marketplace. Results suggest that boards of directors and their audit committees of non-U.S. sample firms before the enactment of the U.S. requirements will need to exhibit greater alignment of their audit committee’s structure and composition with the recent U.S. requirements for audit committees.     

AN INVESTIGATION INTO THE ROLE OF THE MARKET PORTFOLIO IN THE ARBITRAGE PRICING THEORY

This paper investigates the role of the market portfolio in the arbitrage pricing theory (APT). We show that if the multifactor return-generating process put forth in the APT is valid, then unexpected deviations in the return on the market portfolio must be completely explained by unexpected deviations in the underlying return-generating factors. As well, market betas are developed as a combination of return-generating factor sensitivity coefficients. These results lead us to conclude that an empirically significant “market factor’ is evidence of omitted return-generating factors, rather than evidence that the market is a factor. Finally, results obtained when market betas are regressed against factor sensitivity coefficients are consistent with these insights. The results suggest that there are at least three return-generating factors. This evidence does not rely on ex post pricing of estimated factors.     

FURTHER EVIDENCE ON DIVIDEND YIELDS AND THE EX-DIVIDEND DAY STOCK PRICE EFFECT

Ex-dividend day stock price behavior supports a tax clientele effect. This effect is still found after the Tax Reform Act of 1986. Results reflect an effective tax advantage for capital gains taxes payable at realization, versus dividend taxes due quarterly. Evidence also supports short-term trader participation in the ex-day phenomenon when the difference between dividend income and the ex-dividend-day price decrease exceeds transactions costs to trade. Results contradict prior research where a tax clientele effect is not found, but align with this prior research when including a small number of contaminated observations.
