我国海洋养殖资源资产流失量价值模型构建

海洋养殖资源资产的流失已成为制约养殖业发展的重要因素之一。本文通过对养殖资源及养殖资源资产流失的界定,在资源所有者的所有权受损和海域低效利用基础上提出流失量价值即为海洋养殖资源资产价值与国家养殖资源资产总收益的差值,并将海水资源价值、环境成本价值和养殖成本价值作为养殖资源资产的总价值。     

How many voters are needed for paradoxes?

Summary. This paper presents a general procedure for finding profiles with the minimum number of voters required for many important paradoxes. Borda's and Condorcet's classic examples are revisited as well as generalizations. Using Saari's procedure line, we obtain an upper bound for the minimum number of voters needed for a profile for which the Condorcet winner is not strictly top ranked for all weighted positional procedures. Also we give a simple upper bound on the minimum number of voters needed for a set of prescribed voting outcomes. In contrast to situations wherein small numbers of voters are needed, we consider paradoxes requiring arbitrarily large numbers of voters as well as large numbers of alternatives. Finally we indicate connections with statistical rank based tests. Received: April 18, 2001; revised version: May 25, 2001     

科技信用制度建设的回顾与展望

科技信用缺失给国家和社会带来了极大危害.我国自20世纪90年代以来,从加强国家科技计划项目和科学基金的管理入手,制定了一系列规范科技人员行为的政策法规,为科技信用制度建设奠定了基础.今后,这项工作的重点是：制定科技人员信用规范,建立信用信息评价指标体系,提高指标量化评价的科学性,完善信用数据库和信用信息共享平台系统,构建失信行为惩戒机制.     

The conservative equal costs rule, the serial cost sharing rule and the pivotal mechanism: asymptotic welfare loss comparisons for the case of an excludable public project

We examine the asymptotic behavior of two strategyproof mechanisms discussed by Moulin for public goods – the conservative equal costs rule (CER) and the serial cost sharing rule (SCSR) – and compare their performance to that of the pivotal mechanism (PM) from the Clarke–Groves family. Allowing the individuals’ valuations for an excludable public project to be random variables, we show under very general assumptions that expected welfare loss generated by the CER, as the size of the population increases, becomes arbitrarily large. However, all moments of the SCSR’s random welfare loss asymptotically converge to zero. The PM does better than the SCSR, with its welfare loss converging even more rapidly to zero.

关于商业银行贷款呆账准备金制度的分析

对贷款的会计处理和计提呆账准备金的实践是银行业管理和控制风险的基本要素,财政部已多次颁布了有关的管理办法。这些办法的出台对于商业银行防范和化解金融风险有着积极的意义,但也存在一些问题与不足。本文针对这些问题,结合国际惯例和我国实际情况,提出了改革和完善我国商业银行贷款呆账准备金制度的对策和建议。     

当前我国农业保险发展的主要问题及对策建议

我国农业保险正面临着极好的发展机遇,出现了良好的发展势头.但目前仍然存在制约我国农业保险发展的诸多因素,主要是:农业风险本身的可保性差;农业保险经营技术落后;农民收入低,政府投入少;法律法规建设缺位等.我国农业保险要健康有序的发展,必须改进农业保险经营技术;建立有效的再保险机制;增加政府投入,逐步实行以支持农业保险为主的农业保护政策;加快农业保险立法进程,使农业保险走上规范化制度化发展的轨道.     

我国银行贷款违约损失率影响因素的实证分析

本文利用某国有商业银行的贷款数据资料，运用主成因子分析对贷款样本的LGD进行统计分析并确定影响因素的重要性及排序。本文结论为：影响我国商业银行贷款LGD的因素依次为企业的信用等级、贷款担保方式、企业的行业属性；企业规模、企业经济类型、贷款担保方式等因素对LGD的影响都很弱。此外，本文验证了PD和LGD之间存在一定的关系，并非相互独立。
