Equity diversification among the four Asian NICs

Recent studies have indicated the potential gains to U.S. investors from international portfolio diversification. Due to the rapid growth of the four Asian newly industrialised countries (NICs), namely, Hong Kong, Singapore, South Korea and Taiwan, it is believed that U.S. investors will become increasingly interested in these equity markets. The purpose of the present study is to investigate from the U.S. perspective, the prospects of diversifying across the countries. The results indicate that a diversified portfolio among these markets yields a higher return-to-risk ratio than investing in the U.S. market alone.The authors are with the School of Management, National University of Singapore.     

Pupils' attitudes to technology in key stage 3 of the national curriculum: A study of pupils in South Wales

This paper describes part of a continuing research project based at the University of Wales, Swansea, which is investigating pupils' attitudes to a range of national curriculum subjects. There has been no major national funded project to evaluate the national curriculum from pupils' perspectives. The market economy philosophy adopted by the present government is restricted in the meaning of choice given to consumers of education. Pupils' opinions are rarely sought out.The paper describes the results gained from a Likert-type attitude scale and subsequent follow-up interviews with a selection of pupils aged 13 and 14 years in secondary schools across South Wales.     

Can antitakeover activity really create wealth? Evidence from Australia

This paper examines management-induced antitakeover activity which occurred in Australia in the late 1980s. The particular event studied is unique in Australia and requires shareholder approval to amend a company's Articles of Association to incorporate an antitakeover clause. The results show that there are strong positive wealth effects surrounding this management-initiated antitakeover activity, and that there is some evidence of a positive relationship between these abnormal returns and institutional holdings.Scott Armstrong is Investment Analyst, Bankers Trust Australia Limited, Sydney, Australia.

International business research output and rankings of Asia-Pacific universities: A 40-year time-series analysis

This study measures and ranks the performance of countries and academic institutions based on a 40-year analysis of publications appearing in 14 leading business and management journals. The focus is on the evolution of Asia-Pacific institutions in international business research output during this period. In addition, an examination is performed to identify factors associated with Asia-Pacific institutions that have achieved the highest rankings. This research shows that the Journal of International Business Studies and the Journal of World Business were central in spreading international business research, as well as in supporting research by authors from the Asia-Pacific region. Further, schools such as Harvard, Wharton, and University of South Carolina have maintained the highest ranks in research output throughout the 40-year period, but recent years have witnessed the emergence of the Chinese University of Hong Kong and University of Hong Kong, among others, in those top ranks.     

基于恒速压汞的储层微观孔隙结构特征研究

储层的微观孔隙结构是指储集层中岩石的孔喉大小、分布及连通关系。有关储层微观孔隙特征的研究对于准确评价储集层性能及后续开采措施的选择尤为重要。采用恒速压汞法对南五区二类储层微观孔隙结构特征进行研究。根据压汞实验得到各微观孔隙结构的特征参数,与渗透率建立散点分布图,研究各孔隙结构参数对渗透率的影响程度,得出相关系数的大小,进而对各微观孔隙结构参数进行主次划分。在此基础上重点统计各主要参数的压汞实验结果,结合渗透率分布,得到各参数的平均值及分布范围,分析南五区二类储层的微观孔隙结构特征,为后续渗流规律及聚驱配伍性研究提供依据。

CPF stocks: Prices,returns and volatility

We identify a unique phenomenon in the Central Provident Fund (CPF) stocks where stock prices increase in the absence of fundamental changes in firm value. CPF stocks are stocks endorsed by the Central Provident Fund Board in Singapore as approved investment for its members. CPF stocks offer significant price appreciation and value preservation as well as abnormal returns in the bull market before the October 1987 market crash. We find evidence of noise trading in bull markets and price pressure effects that persist through bearish market conditions.The authors are from the Department of Finance and Banking, National University of Singapore.     

Determinants of capital structure of australian trading banks

Using pooled time series/cross section data of Australian trading banks over the 1967–1988 period, this study examines the determinants of bank capital ratios. Little evidence is found to support the tax benefit/bankruptcy cost trade-off, whereas evidence is broadly consistent with the predictions of Myers' pecking order theory in the presence of transactions costs and asymmetric information. Institutional factors, including bank deregulation and type of bank, are also significant determinants of capital management of Australian trading banks.The author is from the University of New South Wales, Kensington, N.S.W.

The intra-day impact of block trades on the Australian stock exchange

This study is concerned with the impact of block trades on transaction prices, themarket bid-ask spread and the frequency of trading on the Australian Stock Exchange. Access to a unique microstructure database enabled the resolution of a number of research design issues in earlier, mainly US-based, studies. Contrary to previous findings, there is no evidence of either a price reversal or changes in the market bid-ask spread surrounding block trades. Further, there is no evidence of an increase in the frequency of trades surrounding block trades. These contrasting results warrant closer inspection of the alternative market structures underlying the different exchanges.The authors are from the Department of Finance, the University of Sydney, Australia. The comments and suggestions of colleagues at the Universities of Sydney, New South Wales, and Queensland are gratefully acknowledged.     

Estimating and comparing learning curves in three Asian economies

This paper consists of two parts. In the first, a method is suggested to isolate the effects of scale economies on learning phenomena by integrating the conventionally specified learning curve with the production function in neoclassical economics. The problem of establishing the variable for measuring experience is dealt with in the estimation procedure. Using this method we estimated the learning curves of 20 industries in the manufacturing sector in Singapore using data taken from 1961 to 1991. More modern industries like electronics, precision instruments and pharmaceutics have steeper learning curves than older industries. Among traditional industries, the food and beverage industry has a greater learning potential than others. In the second part of the paper, the learning curves for 11 common industries in South Korea, Japan and Singapore were estimated and compared. The Japanese industries are found to have steeper learning curves compared to those in Singapore and South Korea.The authors are from the Department of Business Policy, Faculty of Business Administration, National University of Singapore.
