網絡組織成員合作的穩定性模型分析

本文應用博弈論建立了一個網絡組織成員合作的穩定性模型,通過模型分析作者提出網絡組織的穩定性依賴於多種因素,其中,信任機制、懲罰機制是網絡組織穩定的基本因素。本文通過對中國網絡組織的一般性分析,指出特殊主義文化背景下的中國網絡組織的信任機制和懲罰機制更多的來源於非正式制度,而非正式制度作用的空間局限性,是導致中國區際網絡組織穩定性差的重要原因,本文最後提出了中國網絡組織穩定性提升的建議。

Imagined interactions,family money management patterns and coalitions,and attitudes toward money and credit

This study explores the imagined interactions college students have with their parents about money and credit, their attitudes toward credit and money, the ways they say their parents deal with financial decisions, and the communication coalitions regarding finances they perceive existing within their family. Students’ imagined interaction pleasantness is greatest when parents jointly form a plan for paying off credit card debt and lowest when parents argue. When family coalitions exist, students report more frequent imagined interactions. Imagined interaction frequency and pleasantness are related to credit and money attitudes.

Macro-Economic Factors in Credit Risk Calculations: Including Time-Varying Covariates in Mixture Cure Models

The prediction of the time of default in a credit risk setting via survival analysis needs to take a high censoring rate into account. This rate is because default does not occur for the majority of debtors. Mixture cure models allow the part of the loan population that is unsusceptible to default to be modeled, distinct from time of default for the susceptible population. In this article, we extend the mixture cure model to include time-varying covariates. We illustrate the method via simulations and by incorporating macro-economic factors as predictors for an actual bank dataset.     

中国资产证券化信用增级的法律环境问题

资产证券化作为一种新的融资方式,在处置不良资产方面具有明显的作用。信用增级是资产证券化的两大核心技术之一,在当前中国信用体系尚不完善的情况下,信用增级显得尤为重要。信用增级包括内部信用增级和外部信用增级,有效实施这两种信用增级方式在现阶段均存在一定的法律障碍。尽快制定专门的资产证券化法,努力完善信用法律环境,才能保证中国资产证券化的顺利实施。     

A constitutional theory of the family

The paper re-examines the idea that a family can be viewed as a community governed by a self-enforcing constitution, and extends existing results in two directions. First, it identifies the circumstances in which a constitution is renegotiation-proof. Second, it introduces parental altruism. The behavioural and policy implications are illustrated by showing the effects of public pensions and credit rationing. These implications are not much affected by whether altruism is assumed or not, but contrast sharply with those of more conventional models.

A comparison study of computational methods of Kolmogorov–Smirnov statistic in credit scoring

Kolmogorov–Smirnov statistic (KS) is a standard measure in credit scoring. Currently, there are three computational methods of KS: method with equal-width binning, method with equal-size binning and method without binning. This paper compares the three methods in three aspects: Values, Rank Ordering of Scores and Geometrical Way. The computational results on the German Credit Data show that only the method without binning can produce a unique value of KS. It is further proved analytically that the method without binning yields the maximum value of KS among the three methods. The computational results also show that only the method with equal-size binning can be used to evaluate rank ordering of scores. Moreover, it is proved that all the three methods can be used to calculate KS in a geometric way.
