Is Beta Dead or Alive?

The debate about whether beta is dead or alive has heated up once again. We believe the empirical work supporting either side of the argument is limited because market frictions are not adequately addressed. This study clarifies the controversy about the issue by creating a new moving-average beta and analyzing two market anomalies: the turn-of-the-year and the Monday effects. What is discovered in this research is (1) that a fundamental source of the problem underlying the two types of market anomalies is the persistence of market frictions that retard the arbitrage process; (2) that beta is seriously ill if the effects of market frictions are ignored; and (3) that beta is alive and well if the effects of market frictions are accommodated. Also, we show, by using an optimal lead/lag structure, the moving-average beta provides significantly higher explanatory power for the turn-of the-year and the Monday effects than betas created from ordinary least squares regression and Scholes-Williams and Fama-French methods because the moving-average beta accommodates the effects of market frictions into the body of beta itself. This new type of beta, a moving-average beta, is demonstrated to be robust.     

Radical innovations in new product development and their financial performance implications: An event study of US manufacturing firms

At the dawn of the 21st century, global competition continues to increase at an accelerating rate and radical innovation is recognized as a potent weapon for firms to achieve sustainable competitive advantages. Academics, practitioners and consultants share the view that radical innovation is important to the long-term financial success of firms. Nevertheless, empirical studies on the relationship between radical innovation and firm performance have been dominated by survey research, which provided little concrete evidence on the financial impact of radical innovation. In this study we traced the financial performance of publicly traded manufacturing firms in the United States that introduced radical innovations over the period 1986-2000 and examined whether radical innovation could lead to superior financial performance in these firms. We employed the event-study method, matching each sample firm with a control group of firms in the same industry with similar pre-event performance and firm size. Our results show that while radical innovation helps firms maintain sales growth and return on sales (ROS), firm profitability in terms of return on assets (ROA) is not significantly improved. In fact, manufacturers suffer from a decline in profitability upon the introduction of radical innovations in new product development.     

CHANGING VOLATILITY AND THE PRICING OF OPTIONS ON STOCK INDEX FUTURES

This paper presents empirical results regarding the suitability of the Black model for the pricing of options on stock index futures. Whaley's technique is used to present empirical evidence regarding the pricing biases of the model. Information provided by the implied volatilities suggests that model refinements should address the changing volatility issue.     

THE ROLE OF HONG KONG IN SINO-TAIWAN AND SINO-KOREA TRADE, 1981-87

Sino-Taiwan and Sino-Korea trade through Hong Kong has been growing steadily since early 1980's. Direct trade is impossible because of the lack of diplomatic relations between China and Taiwan and China and S. Korea, Thus, an intermediary is essential to carry out the transactions. Then, there is the issue of why Hong Kong is chosen as the major intermediary. This relates to the transportation costs and transaction costs advantages that Hong Kong possesses as an entrepot. As the major intermediary in Sino-Taiwan and Sino-Korea trade, Hong Kong is playing multiple roles. It is serving as an entrepot in commodity trade; as an agent in the export of technology from Taiwan and S. Korea to China; as a mediator in trade disputes; and as the middle-man in some trade related issues such as the application of patent protection and the establishment of trade offices. Above all it is observed that Hong Kong has major roles to play not only in the case of indirect trade, but also in the case of direct trade. In the future, there might not be much chance for the legalization of direct trade. Nevertheless, the recent change in the trade and investment policies of Taiwan and S. Korea has shown that the future prospect of indirect trade is very bright.     

What Drives TBL Reporting: Good Governance or Threat to Legitimacy?

This paper provides two complementary explanations for the adoption of triple bottom line (TBL) reporting by Australian companies. The first explanation is that companies adopt TBL reporting to legitimise their relationship with society because of adverse publicity from the media. The second explanation is that TBL reporting is adopted because of the company's desire to achieve high‐quality reporting and transparency inferred by strong corporate governance. Companies with TBL reporting had significantly more adverse media coverage before implementing TBL reporting than non‐TBL companies. TBL reporting is also significantly and positively related to the existence of an environmental or sustainable development committee and the frequency of meetings of the audit committee.     

Sales recruiting—A major area of underinvestment

How does a firm decide whether the amount now being spent to generate sales force applicants is too much, not enough, or about right? This question can be answered by using information routinely generated by corporate activities and a relatively straight forward decision theory technique. To illustrate that technique, an analysis was conducted for a hypothetical but by no means atypical firm. The results suggest that many corporations could appreciably increase their overall profitability by spending more on sales force recruitment and selection.
