This paper examines the celebrated empirical study of J.L. Evans and S.H. Archer on the relationship between risk reduction and the size of a portfolio. By specifying a suitable return generation model, this widely supported empirical result is shown to be a statistical consequence of their methodology. The mathematical structure of their methodology is presented together with some fresh empirical results on this relationship. Finally the question as to whether a larger number of assets are required in order to achieve the same level of diversification for high beta securities is examined based on a sample of U.K. securities. The results of the tests would not appear to be in support of such a proposition. 相似文献

This paper extends the equivalence relationship between risk/return linearity and portfolio efficiency as derived in Roll (1977) to the case where there is differential taxation affecting investors optimal portfolio choice. Following the formulation of Brennan (1970a), the fundamental linearity relationship is derived which raises serious doubts to the testability of the extendedCAPM that accounts for the effect of differential taxation. Finally by aggregating other imperfections as well as differential taxation into a dividend yield constraint, a different version of theCAPM is derived which offers alternative interpretations of the existing empirical results on the subject. 相似文献

This paper analyzes developments and trends related to China's outward direct and financial investments by examining Chinese firms’overseas acquisitions, China's holdings of US Treasury securities, and the recently formally launched Qualified Domestic Institutional Investor programs. Strategies should be developed to reach optimal decisions for both direct and portfolio investments. We argue that China should have a longer‐term view for both direct and portfolio investments, enabling China to become the leader in Asia while maintaining its sustainable growth objective. China should invest heavily in the development of the Asian bond market and the Asian Currency Fund when making both portfolio and direct investment decisions. 相似文献

Abstract. This study used a sample of 1035 Taiwanese firms to examine the impact of dividend protected employee stock options on stock repurchase and cash dividend policies from 2000 to 2005. This study finds a positive relationship between cash dividends and executive options, implying that executives holding stock options might prefer to distribute cash dividends to boost the stock price. This result, unlike in earlier studies, arises from the dividend protected characteristic of Taiwanese employee stock options. Finally, free cash flow, firm profitability, level of debt, investment opportunities and firm size are found to considerably influence payout decisions. 相似文献

This paper uses a sample of daily returns data from the Paris Bourse to test the predictions of and adjustment procedures implied by the Cohen-Hawawini-Maier-Schwartz-Whitcomb (1983a,b) model of the intervalling effect bias in OLS beta estimates. CHMSW show that the bias diminishes asymptotically to zero as the differencing interval increases and that the sign of the bias depends on a stock's relative value of shares outstanding. We employ the three-pass regression procedure of CHMSW (1983b), but we test a broader set of second pass functional forms and use the Box-Cox (1964) transformation model to verify our chosen form. The CHMSW adjustment procedures are compared with that of Scholes-Williams (1977), and the latter is shown to contain a significant intervalling effect bias. 相似文献

Subsequent to a previous article in JCP (Scherhorn, 1990) outlining a theoretical approach to addictive buying, the authors report on the results of their empirical study of addictive buyers in West Germany. The study indicates that addictive buying is clearly one kind of addiction which may be substituted by other addictions, may take the place of another addiction, or even alternate with other forms of addiction. At the same time, there is substantial evidence that there are special key experiences to which the propensity to addictive buying can be traced. Addictive buyers have been subjected to a specific form of distortion of autonomy: They have felt that for parents, relatives, or neighbours, material goods (money, property, consumer goods) seemed to be more relevant and more important than they themselves. Thus, they have acquired a strong predisposition for using consumer goods as a favourite means of compensating for the lack of self-esteem from which they suffer. This predisposition, however, is reinforced by the fact that consumption and buying increasingly take on the role of a socially favoured means of compensation. 相似文献

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation. 相似文献

This study examines the information conveyed by options and examines their implied volatility at the time of the 1997 Hong Kong stock market crash. The author determines the efficiency of implied volatility as a predictor of future volatility by comparing it to other leading indicator candidates. These include volume and open interest of index options and futures, as well as the arbitrage basis of index futures. Using monthly, nonoverlapping data, the study reveals that implied volatility is superior to those variables in forecasting future realized volatility. The study also demonstrates that a simple signal extraction model could have produced useful warning signals prior to periods of extreme volatility. These results indicate that the options market is highly efficient informationally. © 2007 Wiley Periodicals, Inc. Jrl Fut Mark 27:555–574, 2007 相似文献

AbstractIn this paper, I examine the economic links first between the European Union (EU) and China and then I focus on the economic relationships between Germany and China. The links I will consider include international trade and direct investment. Lastly I highlight some elements of the so-called “German Model” or the “Berlin Way” and examine if they can be of policy relevance to China. There are four main results: first, EU-China trade and investment relationships are strong, deepening rapidly but they are somewhat unbalanced and asymmetric. Second, the economic relationships between Europe and China are focused on manufacturing. Third, the EU-China relationships are primarily Deutschland-centric. Lastly, elements of the “German Model” such as Mitbestimmung, Mittelstand and the German apprenticeship system can have important structural and policy implications as China continues to grow and experiment with reforms aiming at combining stability, harmony and competitiveness. 相似文献
