辽低速油田筛选与分类初探

以辽河油区低速油田为例,讨论了文献中提出的3种低速油田筛选标准,提出了油藏剩余可采储量采油速度的低速油田筛选标准,有助于动态分析和掌握低速油田状况,正确认识开发阶段和开发效果,且排除了一些因采出程度高而形成的“低速”区块,更加符合油田实际。依据该标准筛选出辽河油区低速油田58个。动用石油地质储量占辽河油区己探明原油地质储量的22．2％,占动用地质储量的28．8％。又根据造成油田低速的主要原因分为5类：物性(低渗)低速、岩性低速、油性低速、构造(复杂断块)低速和其他原因低速。不同类型低速油田需要确定相应的开发技术、经济界限。     

抵押风险分析和抵押贷款违约损失率研究

违约损失率是BaselⅡ规定的六大风险指标之一,而抵押是BaselⅡ标准法规定的信用风险缓释工具之一,两者在巴塞尔新资本协议中有着非常关键的地位和作用.本文总结了国内外违约损失率的研究概况,在利用历史数据对我国商业银行抵押贷款的违约损失率进行实证分析后发现：（1）回收率同融资金额成反比;（2）回收率同融资折率成反比;（3）回收率呈“U”型分布.本文的分析有助于进一步探究我国商业银行抵押贷款违约损失率的特征,是量化风险暴露和计算监管资本的基础,并为我们下一步的折率研究做好了铺垫.     

Pricing the risks of default

This paper decomposes default risk into timing and recovery risks. The two default components are explicitly priced as if they were traded in the futures market. We develop estimation strategies evaluating recovery risks and then construct implicit prices of contingent securities reflecting purely the timing risk. The models are estimated on monthly data for rates on certificates of deposit offered by institutions in the Savings and Loan Industry, during the 1987–1991 period. Empirical results support market expectations of lower likelihoods of default after 1989.     

战略型“订单粮食”模式探讨

"订单粮食"作为一种新型的实现粮食产销衔接的经营方式,正受到越来越多的重视,但实施中却存在履约率太低的问题,步履艰难。为从根本上解决此问题,提出战略型"订单粮食"模式,即以建设中国式农场为主,以营造"订单"氛围为辅,努力将种粮大户和散户吸纳到粮食产业化经营体系下,开辟中国的农场时代。

Balancing the scales: recovering from service failures depends on the psychological distance of consumers

The purpose of this research is to enhance knowledge about service recovery by investigating the feelings of psychological distance in the relationship between customers' perceptions of service recovery efforts of the perceived justice dimensions (distributive, procedural, and interactional justice) and attitudinal responses such as satisfaction with service recovery effort and trust in the firm. The results of structural equation modelling analyses suggested that consumers who had positive justice perceptions were likely to exhibit positive attitudinal responses. Consequently, the positive attitudinal responses generated positive word-of-mouth intention about their experiences and encouraged them to continue the service.     

Distance in time between transition economies and the European Union

The time distance methodology used offers a new perspective to the problem, an additional statistical measure, and a presentation tool for policy analysis and debate readily understood by policy makers, media and general public. Disparity between the analysed transition economies and EU countries is considerably smaller for other indicators than for GDP per capita. Compared with Ireland, Portugal and Greece Slovenia was in 1995 in 13 cases behind (but time lag of Slovenia never exceeded 10 years) and in 13 cases ahead of them. Sicherl (1997a) discusses application of S-distance to time series regressions, models, forecasting and monitoring. First version received: October 1995/final version received: April 1998
