Informed trading and liquidity in the Shanghai Stock Exchange

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.

A STATE-SPACE PARTITIONING METHOD FOR PRICING HIGH-DIMENSIONAL AMERICAN-STYLE OPTIONS

The pricing of American-style options by simulation-based methods is an important but difficult task primarily due to the feature of early exercise, particularly for high-dimensional derivatives. In this paper, a bundling method based on quasi-Monte Carlo sequences is proposed to price high-dimensional American-style options. The proposed method substantially extends Tilley's bundling algorithm to higher-dimensional situations. By using low-discrepancy points, this approach partitions the state space and forms bundles. A dynamic programming algorithm is then applied to the bundles to estimate the continuation value of an American-style option. A convergence proof of the algorithm is provided. A variety of examples with up to 15 dimensions are investigated numerically and the algorithm is able to produce computationally efficient results with good accuracy.     

Strategic Responses to Competitive Pressure: The Case of Township and Village Enterprises in China

This study assesses the configuration between strategic orientation and industrial environment for Chinese township and village enterprises (TVEs), the organizational form which has played an increasingly important role in Chinese economic development and structural reform. We argue that the complexity, dynamism, and hostility of the industrial environment influence TVE managers' perception of competitive pressure, which in turn affects the firm's strategic orientations such as innovativeness, proactiveness, risk-taking, and analysis. Our analysis, based on a survey of TVE managers in Tinjin and Jiangsu, demonstrates that complexity and dynamism of industrial competition have a systematically positive impact on TVE's innovativeness, proactiveness, risk-taking, or analysis. Environmental hostility is not significantly associated with any strategic orientations adopted by Chinese TVEs. Implications of the findings are discussed.     

Do local analysts know more? A cross-country study of the performance of local analysts and foreign analysts

This paper examines whether analysts resident in a country make more precise earnings forecasts for firms in that country than non-resident analysts. Using a sample of 32 countries, we find an economically and statistically significant local analyst advantage even after controlling for firm and analyst characteristics. The local advantage is high in countries where earnings are smoothed more, less information is disclosed by firms, and firm idiosyncratic information explains a smaller fraction of stock returns. It is negatively related to whether a firm has foreign assets and to market participation by foreign investors and by institutions, and positively related to holdings by insiders. The extent to which U.S. investors underweight a country's stocks is positively related to that country's local analyst advantage.     

对我国企业家制度的几点思考——基于国有企业的视角

企业家是稀缺资源，是推动国民经济发展的主要力量。企业家制度及企业家队伍建设是我国国企改革中一个重要的环节。2003年国务院国资委成立以来，对企业家制度进行了一系列的设计和安排，企业家队伍建设也取得了一定的成效，通过对这些制度的思考提出一些看法。     

从生态文明建设看企业环境信息公开

建设生态文明是我国经济社会发展的重要方向。企业作为经济社会发展的重要主体,其可持续发展水平直接影响国家的生态文明建设。企业环境信息公开是企业为促进与利益相关者之间的环境信息交流而进行的信息披露行为。文章从生态文明建设视角,分析了推进企业环境信息公开的必要性,介绍了我国企业环境信息公开现状及存在的问题,并提出在国家层面做好顶层设计的相关建议。
