Default Premiums in Commodity Markets: Theory and Evidence

We model the effect of nonperformance risk on forward and futures pricing and look for evidence of nonperformance risk in precious metals futures prices from the “Hunt Brothers”episode. Changes in default premiums are measured and related to the sequence of events in the metals markets during this period. Results suggest first that ex ante costs of nonperformance can be a significant, priced factor in commodity markets and second that the arrival of new information is often associated with changes in these costs. The evidence has implications for both theoretical and empirical research on commodity markets.     

A PBOBLEM IN PRICES AND QUANTITIES

"Most of us were brought up to employ such index numbers as Sauerbeck's… much too lightheartedly, and without sufficient warning that… the actual divergences between these indexes and the Purchasing Power of Money might prove to be, if we could calculate them, of very great significance both theoretical and practical."     

我国房产税试点效果评析与房产税作用探究

目前我国房产税在持有环节的征收处于试点阶段，其推进和改革仍有很多争议。文章在总结国际上发达国家房产税征收及我国房产持有环节税收试点情况的基础上，从三方面分别探讨了在我国房价高启的背景下开征持有环节的房地产税的作用。但是这些作用还不能全面准确地涵盖我国应征收房地产税的所有层面，由此提出了适合我国国情的差别化房地产税收政策的构建思路。     

对我国开展矿产资源综合区划相关问题的思考

开展矿产资源综合区划是落实国家战略、保障我国资源安全的必然要求,同时也是矿产资源区划研究的重要趋势。在阐述开展矿产资源综合区划必要性和可行性的基础上,探讨了对矿产资源综合区划概念、内涵、特点、区划体系,以及划分方法与指标体系设计等方面的思考认识,以期为我国矿产资源综合区划的实证研究提供参考。     

Trade Union Influence on Human Resource Management Practices

This paper examines the influence of unions on 37 human resource management practices, ranging from hiring policies to promotion practices. The logistic regression results show that unionization is positively associated with a more formal approach to human resource management. There is, however, a shift from performance-based payment systems and performance appraisal (P.A.) functions in unionized settings. The results also indicate that union firms are more selective of new hires by adopting a formal probationary period for new employees. Last, the estimates suggest that the impact of unions on training programs varies with the nature of the programs.     

区域能源消费总量控制方法述评

相对于提高能源利用技术和发展清洁能源而言,控制能源消费总量具有操作简单且快速有效的优势。本文对现有的有关研究文献进行梳理、比较各种目前应用较为广泛的区域能源消费总量控制方法,总结目前已经得到的研究成果、讨论现存的争议、分析进一步的研究方向。分析发现:部分现行的节能政策难以取得预期效果,且目前关于能源消费总量控制手段的研究多集中于价格、优化产业结构和提高能源效率等方面,且没有取得统一的结论。
