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

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.  相似文献

Dufour and Engle (J. Finance (2000) 2467) find evidence of increased presence of informed traders when the NYSE markets are most active. No such evidence, however, can be found by Manganelli (J. Financial Markets (2005) 377) for the infrequently traded stocks. This article investigates the issue of informed trading and its relation to liquidity in Shanghai Stock Exchange. Consistent with the hypothesis that information-based trade exists for all stocks, our findings suggest an increased presence of informed trading in both liquid and illiquid stocks when markets are active. Moreover, for the actively traded stocks, our results support the price formation model of Foster and Viswanathan (Rev. Financial Studies (1990) 593) that activities of informed traders deter uninformed investors from trading, thereby reducing market liquidity.  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

While many studies of knowledge exchange have been undertaken in private and service organizations, government and R&D enterprises, few have studied scientific inter‐organizational collaborations. Furthermore, in the literature on international networks there has been a tendency to assume that knowledge exchange will be inevitably enhanced by global dispersion. Two linked dynamics deserving further study are the role of geographic proximity and the role of information and communication technologies in facilitating knowledge flow across international networks. Studies of intra‐ and inter‐firm knowledge transfer, managerial work values and cultural norms all point to China as being a fascinating counterpoint for the way knowledge exchange might occur in Europe. So in this study of the ATLAS collaboration, a ‘big science’ global network of 3,500 physicists, we explore the perceptions of two subgroups: UK physicists working in Europe and Chinese scientists based in Beijing and HeFei. Findings from 24 interviews and non‐participant observation reveal that face‐to‐face working at European Organization for Nuclear Research (Geneva) is not without its difficulties, but for a variety of sociocultural reasons, it is primarily the Chinese scientists who perceive themselves to be inhibited from full participation in effective knowledge exchange.  相似文献

Abstract

In 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

This paper studies the relationship between firm size and technical efficiency of manufacturing enterprises in Shanghai's manufacturing sector from 1989 to 1992. Although our empirical results show that technical efficiency is increasing in the firm size, the group of the smallest enterprises (0–99 workers) have very high technical efficiency. The group of enterprises with size of 100–249.9 workers have the lowest technical efficiency while the largest size (1000 workers or above) group usually have the highest technical efficiency. Finally, technical efficiency computed from net industrial product has large upward biases compared with that computed from gross industrial product.  相似文献
