Stochastic Technology, Risk Preferences, and Adoption of Site-Specific Technologies

A model of farmer decision making is developed to determine the extent to which uncertainties about soil fertility and weather affect the value of site-specific technologies (SSTs) using jointly estimated risk and technology parameters. Uncertainty can lead risk-averse farmers to apply more fertilizers and generate more pollution than in the certainty case. Ignoring uncertainty and risk aversion would overestimate the economic and environmental benefits of SSTs and underestimate the subsidy required to induce adoption. Accounting for uncertainties and risk preferences might explain the low observed adoption rates of SSTs. Improving the accuracy of SSTs would increase the incentives for adoption.

滚压抽油杆常见质量问题及原因分析

抽油杆滚压加工作为一种修复抽油杆的新工艺具有良好的经济效益,但是由于其自身的工艺设计和质量控制的特点,在使用过程中出现了一些早期失效问题。通过对这些失效的抽油杆的宏观形貌分析、材料的化学成分及金相组织分析,认为滚压抽油杆的杆体直径、表面质量、直线度不符合标准,镦锻前加热设备设计不合理是造成滚压抽油杆早期失效的主要原因。最后提出了确保滚压抽油杆符合标准、提高其质量的方法。     

大股东治理机制背景的独立董事功用

独立化后的独立董事会削弱大股东治理机制的有效性,其本身也难以发挥监督经理层、保护股东利益的作用,从而可能诱发股东与经理层之间的利益冲突,损害股东整体利益。基于我国上市公司存在双重委托代理问题及投资者法律保护较弱的现实情况,构建具有中国特色的公司治理结构应从两方面着手:政府选择合适的国家终极产权控制方式和合理的代理人行使国有股股权优化大股东治理;制定和切实实行保护小股东的外部强制规则。     

Study on Problems of Group of Companies Listing as a Whole and Corporate Governance

Listing as a whole refers to reorganize all the enterprises＇ businesses, establish a stock corporation and increase capitals to list by issuing social public shares. TCL Group and Wuhan Iron and Steel （Group） Corporation have set a good example for other groups of enterprises that have parts of their assets listed, and will guide groups of enterprises which are affiliated to the center authority of China to list their assets. Listing as a whole, is beneficial to make clear the complex share-holding relationships between the group and its affiliates. It will also be beneficial to improve the whole structure of corporate governance, decrease the correlation trade, reduce the information disclosure cost, and solve the problem of the correlation trade between the group and its affiliates. However, it is far beyond the standard of what standardized corporate governance requires. Standardized corporate governance at least possesses two factors： One is the equality of the rights of shareholders, namely the same share with the same rights; the other is the clear rights boundary of the stakeholder and the existence of the efficient mechanism of equilibrium of rights. These two factors do not have the necessary relations to whether the group list as a whole or not, but depend on the maturity of the market and the soundness of the law and regulation.
