This paper is a study of the Fama and French (1992) analysis in the UK context. Consistent with their findings, our results do not support a positive relationship between beta and average monthly returns. We find that book-to-market equity and market leverage are consistently significant in explaining UK average returns. Contrary to the Fama-French evidence, size has an insignificant effect on average returns. A puzzling negative beta-returns relationship is found in some monthly regressions,and results based on annual data reveal a reversal of betas for the smallest-size portfolios. Some possible explanations are offered for these findings. 相似文献

Simulation experiments are used to compare OLS and several principal components (PCR) estimators of the classical linear regression model. According to mean square error and mean absolute error criteria OLS dominates PCR in these experiments. 相似文献

Using a set of 18 accounting journals and a sub-set of top five journals from 1991 to 2002, we rank the research productivity in accounting for a total of 119 Asia-Pacific universities. For the whole sampling period, the top five universities are the University of New South Wales, Hong Kong University of Science and Technology, Nanyang Technological University, the University of Sydney, and City University of Hong Kong. A number of prominent universities with long school history are not ranked in the top 20. During the second half of the sampling period, Hong Kong and Singaporean universities have shown the most improvement while some Australian universities have exhibited decline in research output. Also, Hong Kong University of Science and Technology replaces University of New South Wales as the first-ranked university in the period of 1997–2002. When compared with other North American universities, the accounting productivity of the top 20 Asia-Pacific institutions is comparable with that of leading universities in North America. The comparison is even more favorable to the Asia-Pacific universities during the period of 1997–2002. 相似文献

This paper represents the first attempt to apply a stochastic dominance (SD) approach to examine the efficiency of the UK covered warrants market. Our empirical analyses reveal that neither covered warrants nor their underlying shares stochastically dominate the other, indicating the nonexistence of potential arbitrage gains in either wealth or utility, which implies market efficiency. To complement the SD results, we also employ a likelihood ratio (LR) test to examine information efficiency. A bootstrap methodology is developed to correct the size distortion of the LR test. Our findings show that UK covered warrant returns efficiently reflect the return information of the underlying shares. 相似文献

This study examines leader?Cmember exchange (LMX) as a mediator of the relationship between benevolent leadership and follower task performance and extra-role performance. Using a sample of 223 leader?Cmember dyads in a nonprofit organization in the People??s Republic of China, results indicate that benevolent leadership and LMX are positively related to follower task performance and organizational citizenship behavior towards the organization (OCBO). Findings also support that LMX partially mediates the relationship between benevolent leadership and follower task performance as well as fully mediates the relationship between benevolent leadership and OCBO. Implications for the theory and practice of leadership in Asia are discussed. 相似文献

The use of personal response systems (PRSs) to support the learning process is increasing. This study examines the impact of PRSs from individual learners’ and instructors’ perspectives on individual learners’ engagement with PRSs and their learning performance. Data were collected from a sample of 236 undergraduate bachelor of business administration students in the School of Business at a Hong Kong university. The results indicated that the learner interface was important to individual learners’ engagement with PRSs and their learning performance. Instructor attitude and technical competence had significant impacts on learning performance. Engagement with PRSs partially mediated the effect of both perspectives on learning performance. Implications for the theory and practice of individual learners’ learning performance are discussed. 相似文献

The research productivity of board members of the top academic finance journals—Journal of Finance, Journal of Financial Economics, Review of Financial Studies, Journal of Financial and Quantitative Analysis, and Financial Management—is investigated. Discipline specific benchmarks for substantial research excellence are determined and an evaluation of influential
finance journals is presented. Publication in Journal of Finance is the most notable benchmark for selection to the editorial board of any of the finance journals evaluated. The results
imply that publishing one article in Journal of Finance, Journal of Financial Economics or Review of Financial Studies in a 5-year period coupled with additional appearances in the broader top tier finance journals would be representative of
exceptional research achievement.

This paper empirically investigates the pricing factors and their associated risk premiums of commodity futures. Existing pricing factors in equity and bond markets, including market premium and term structure, are tested in commodity futures markets. Hedging pressure in commodity futures markets and momentum effects is also considered. This study combines these factors to discuss their importance in explaining commodity future returns, while the literature has studied these factors separately. One of the important pricing factors in equity and bond markets is liquidity, but its role as a pricing factor in commodity futures markets has not yet been studied. To our knowledge, this research is the first to study liquidity as a pricing factor in commodity futures. The risk premiums of two momentum factors and speculators’ hedging pressure range from 2% to 3% per month and are greater than the risk premiums of roll yield (0.8%) and liquidity (0.5%). The result of a significant liquidity premium suggests that liquidity is priced in commodity futures. 相似文献
