信用卡开卡意愿与使用频率影响因素研究

信用卡发卡量猛增,但20％的激活率却让人茫然,虽然针对信用卡的研究众多,但缺乏从消费者态度、意愿和行为的角度来剖析睡眠卡的成因及其激活措施。本研究基于技术接受模型理论,利用结构方程模型分析了信用卡相关知识、感知方便性、感知实用性、感知风险、金钱与信用态度、信用卡态度等对信用卡开卡意愿的影响。

CSI测评模型共线性问题的一个模拟研究

多重共线性是多元统计分析中经常遇到的问题,特别是,多重共线性问题对顾客满意度指数测评可能造成的影响一直是一个值得关注的问题.本文以我国顾客满意度指数服务行业基础测评模型为研究对象,运用蒙特卡罗方法,研究模型变量共线性对测评模型的影响.结果表明,在使用偏最小二乘方法构建顾客满意度指数模型时,测评模型有很好的估计精度,并且基本不受变量共线性显著影响.     

Decisions Made by the Controlling Shareholder Under Financial Crisis

We employ a sample of 12,200 observations from 2,321 companies listed on the Shanghai and Shenzhen Stock Exchanges in China between 2005 and 2013 to test five hypotheses. The empirical results show that the cost of tunneling and ownership structure play important roles in restraining incentives to expropriate firms. Financial crisis will reinforce the incentive to propping rather than tunneling with higher ownership concentration. Moreover, controlling shareholders of state-owned enterprises show a stronger motivation to prop up during crisis periods than do those of non-state-owned enterprises. The results indicate that both an entrenchment effect and a convergence-of-interest effect actually exist and vary according to ownership structure and macroeconomic circumstances.

Securitization of Longevity Risk in Reverse Mortgages

Abstract

The reverse mortgage market has been expanding rapidly in developed economies in recent years. The onset of demographic transition places a rapidly rising number of households in an age window in which reverse mortgages have potential appeal. Increasing prices for residential real estate over the last decade have further stimulated interest.

Reverse mortgages involve various risks from the provider-s perspective that may hinder the further development of these financial products. This paper addresses one method of transferring and financing the risks associated with these products through the form of securitization. Securitization is becoming a popular and attractive alternative form of risk transfer of insurance liabilities. Here we demonstrate how to construct a securitization structure for reverse mortgages similar to the one applied in traditional insurance products.

Specifically, we investigate the merits of developing survivor bonds and survivor swaps for reverse mortgage products. In the case of survivor bonds, for example, we are able to compute premiums, both analytically and numerically through simulations, and to examine how the longevity risk may be transferred to the financial investors. Our numerical calculations provide an indication of the economic benefits derived from developing survivor bonds to securitize the “longevity risk component” of reverse mortgage products. Moreover, some sensitivity analysis of these economic benefits indicates that these survivor bonds provide for a promising tool for investment diversification.
