农会组织与建设新农村——基于台湾经验的政策建议

台湾“农村建设”的经验表明，只有通过农民自有组织的努力，农业发展与乡村发展计划始能有效推动。因此，为了使“建设新农村”的各项政策有真正的行动主体，中国农村需要建立以“农有、农治、农享”为原则、以属地主义为组织体系和议行分立为治理结构的农会组织。     

An Intertemporal CAPM Approach to Evaluate Mutual Fund Performance

Merton (1973) and Campbell (1993) have demonstrated that if an investor anticipates information shifts, he will adjust his portfolio choice today in an attempt to hedge these shifts. Exploiting these insights, we construct a new performance measure to evaluate fund managers' hedging ability. This new measure is different from two widely adopted performance evaluation measures: securities selectivity and market timing. Moreover, an econometric methodology is developed to simultaneously estimate the magnitudes of these three portfolio performance evaluation measures. The results show that mutual fund managers are on average with positive security selection and negative market timing ability. Furthermore, the mutual funds with investment style classified as Asset Allocation generally have positive hedging timing ability.     

中国油气管道发展现状及前景展望

到2006年底，中国长输油气管道总长度已超过5万千米，其中天然气管道约5万千米，原油管道约1．5万千米，成品油管道约0．56万千米，形成了初具规模的跨区域油气管网。2006年，中国多条天然气干线联络管道相继建成，冀宁联络管道连结陕京二线和西气东输，淮武联络管道连接西气东输和忠武线，提高了中国天然气供应系统的安全可靠性。此外，区域性输气管道建设方兴未艾，广东LNG管道工程正式投产运行，西部管道以及珠三角成品油管道等多条成品油干线管道陆续建成。目前，中国已形成多个油气区域管网，其中包括川渝、华北及长三角地区比较完善的区域性天然气管网，中南、珠三角地区的区域性天然气管网主体框架，以及东北、西北和华北的区域性原油管网。近几年，中国的钢铁冶炼和制管水平大幅度提升，X70等高钢级管线钢得到了大规模应用，X100管线钢的研制开发获得成功，陆上管道施工的部分技术已达到国际一流水平。“十一五”期间，中国油气管道工业将继续得到长足的发展。

Investor protection and analysts’ cash flow forecasts around the world

We find that analysts are more likely to provide cash flow forecasts in countries with weak investor protection. This finding is consistent with our hypothesis that market participants demand (and analysts supply) cash flow information when weak investor protection results in earnings that are less likely to reflect underlying economic performance. Our results suggest that information intermediaries respond to market-based incentives to attenuate the adverse effects of country-level institutional factors on earnings’ usefulness. These findings contribute to the literature by shedding light on the institutional determinants of analysts’ research activities, and on the nature of the financial information they generate.

Optimal information revelation in procurement schemes

A buyer procuring a single input possesses private information about each potential supplier's degree of fit with the buyer's needs. She can search among suppliers either sequentially or simultaneously. As long as the distribution of the fit parameter is not overly skewed to the left, sharing information with suppliers yields intensified price competition under simultaneous search. Moreover, the buyer cannot benefit by providing suppliers additional information beyond their own fitness parameter. Information revelation is never optimal with sequential search.     

Deregulation and environmental differentiation in the electric utility industry

This paper analyzes how economic deregulation impacts firm strategies and environmental quality in the electric utility industry. We find evidence that the deregulation introduced to this historically staid industry has stimulated environmental differentiation. Differentiation is most likely to appear where its point of uniqueness is valued by customers, and we confirm this relationship in our sample. Specifically, utilities that served customers who exhibited higher levels of environmental sensitivity generated more ‘green’ power. The tendency for firms to differentiate in this way is lessened if they are relatively more dependent on coal‐fired generation or relatively more efficient. Thus, there is evidence that firms sort themselves into either differentiation or low‐cost strategies as the competitive realities of a deregulated world unfold. Deregulation and the ensuing environmental differentiation illustrate how utilities exploited formerly unmet customer demand for green power. The result has been greater levels of renewable generation and, hence, a cleaner environment. Copyright © 2007 John Wiley & Sons, Ltd.
