The Valuation Differential between Class A and B Shares: Country Risk in the Chinese Stock Market

The Chinese stock market has been characterized by a strict segmentation between domestic and foreign investors, with listed companies issuing Class A shares to domestic, and Class B shares to foreign, investors, respectively. Entitled to the same rights and obligations, however, the two classes of shares are traded at significantly different prices. The valuation differential is attributable to the different sets of investment opportunities available to domestic versus foreign investors and their risk tolerance. Foreign investors would require a higher rate of return to adjust for the country‐specific risk related to the Chinese stock market. The country risk of China can be decomposed into political risk, exchange rate risk, interest rate risk and market risk. Empirical tests provide strong evidence to support the decomposition model, showing the political risk of China as an important component.

Institutional investors and firm performance: Evidence from IPOs

We investigate the post-IPO evolution of institutional investor holdings and the manner in which operating performance is related to these holdings. During the first year after the IPO, average institutional holdings increase from 24% to 36% of shares outstanding and stabilize at about 42% by the end of the second year. We document that post-IPO operating performance is positively related to institutional holdings, but this relation subsides in the third year after the IPO. Overall, our findings indicate that institutional ownership is a valid indicator of the firm’s operating performance in its initial years as a public company.     

机构投资者能提高开放式基金的业绩吗

本文通过对开放式基金的实证研究,发现开放式基金的机构投资者持股比例与超额收益率呈显著的负相关关系,即机构投资者并不能提高开放式基金业绩。相反机构投资者持股比例越高,开放式基金业绩可能越低,这与已有研究文献的结论不同。同时还发现基金公司收取的管理费用和基金的累计净值对基金业绩有正面的影响。     

A survey of enterprise reforms in China: The way forward

The strategic importance of the state-owned enterprise (SOE) sector to the Chinese economy cannot be underestimated, thus the success of SOE reform is a significant factor in China's future economic prosperity. The dilemma facing state authorities is to develop market-orientated corporations while at the same time coping with potentially high unemployment and a range of equity and social justice issues. This paper presents an analysis of the current issues in SOE reform in China, drawing on relevant empirical evidence, and proposes a strategic direction and a framework for reform that challenges the recently announced program of privatization of listed SOEs. The literature indicates that state ownership is generally negatively correlated to performance. Conversely, Legal Person ownership positively influences performance. Other forms of private ownership are generally positively correlated to performance, with institutional ownership showing significant promise. Consequently, the divesture of state ownership is recommended and could be accomplished over three or four tranches. The state could divest its ownership by auction to strategic investors, both domestic and foreign, and in the next tranche an auction to the broad populace through units in mutual funds. The final proposed tranche being a distribution to nationwide pension funds to support retirement schemes, which should be made nationwide. Finally, listed firms should also issue shares as rights issues to offer present shareholders protection from dilution.     

Institutional antecedents and performance consequences of employment security and career advancement practices: Evidence from the people's republic of China

In this study, we examine the provision of employment security and career advancement opportunities in firms of diverse institutional ownership and the impact of such practices on employee and firm outcomes. The sample included 478 state‐owned and non‐state‐owned firms (i.e., domestic private firms, Sino‐foreign joint ventures, and wholly‐foreign‐owned firms) in the People's Republic of China. We found that the provision of employment security was greater in state‐owned than in non‐state‐owned firms. The provision of career advancement opportunities in domestic private firms and Sino‐foreign joint ventures was similar to that in wholly foreign‐owned firms, but greater than that in state‐owned firms. The provision of career advancement opportunities was positively related to employee organizational commitment, citizenship behaviors, and firm performance. The provision of employment security was positively related to employee organizational commitment, but not to citizenship behaviors or firm performance. © 2008 Wiley Periodicals, Inc.     

竞争制造商持股关系的供应链分析

考虑两竞争制造商通过共同零售商销售替代产品的两层供应链系统,分别研究制造商未持股和制造商单向持股情形下供应链成员的决策及其对供应链绩效的影响。对制造商单向持股存在持股方与售股方都可以接受的持股成本区间,但这会损害零售商收益和供应链整体绩效,随着持股比例的增加,对供应链绩效的损害会进一步加剧。     

The Role of Financial,Macroeconomic, and Non-financial Information in Bank Loan Default Timing Prediction

We assess the use of bank loan information in predicting the timing to default. We use unique data on defaults in small and medium enterprises maintained by the Central Bank of Portugal which includes financial accounting and macroeconomic indicators, as well as non-financial information. The findings are indicative of the incremental predictive ability of non-financial information over and above macroeconomic and financial accounting information in the baseline, industry, and in- and out-of-sample models. Specifically, total credit secured by firms is, as expected, negatively and significantly related to default. Gross domestic product is negatively and significantly related to default, and benchmark market rate is positively and significantly associated with default. The findings also reveal that firms which are operated by partners, which have stronger financial support from partners, and which possess operational assets exhibit lower hazards of default. The study indicates that non-financial information and macroeconomic indicators assessed alongside financial accounting data can significantly improve the forecasting performance of default models.     

To whom are IAS earnings informative? Domestic versus foreign shareholders' perspectives

Using a sample from the Helsinki Stock Exchange, this paper analyses the information content of dual disclosures of IAS (International Accounting Standards) and LAS (Local Accounting Standards) earnings. Their information content to foreign and domestic shareholders can be distinguished from each other as the unrestricted shares (available to foreign and domestic investors) and the restricted shares (available to domestic investors only) of the same set of companies were listed separately during 198492. The information content is tested with regressions using market-adjusted stock returns measured from the fifty-week period ending in the week of financial statements release. The overall findings suggest that restating local GAAP earnings according to the IAS helps to meet foreign investors' information needs, but is of limited use to domestic investors.
