随着存款保险制度的推出以及金融机构退出机制的完善,国家声誉将逐渐退出银行无形资本。在激励相容的金融监管趋势下,特许权价值等市场约束力量会显著影响到商业银行的风险承担。在此逻辑基础上,以我国16家上市商业银行为研究对象,一方面探讨特许权价值影响下不同产权结构的商业银行的最优救助机制,另一方面通过最优救助临界指标,利用银行重组模型,推导合理的存款保险风险差别费率。 相似文献

We investigate the impacts of job position and survey time period on employee’s organizational commitment of insurance company after the merger. Our results show that both job position and survey time period are significant determinants to employee’s organizational commitment. Results also show that there is no interaction effect between survey time period and job position. For each year, during the survey time period, the mean of organization commitment of agent employees is significantly higher than staff employees. The mean difference of organizational commitment between agent and staff employees shrank year by year during the survey time period. 相似文献

This is an expository paper on applications of statistics in the field of general insurance, also called non‐life insurance. Unlike life insurance where advanced statistical techniques have long been part of financial mathematics and actuarial applications, their use is only relatively recent in non‐life insurance. The business model of insurance companies, especially those active in non‐life insurance, has seen dramatic changes over the last 15 years. The aim of this paper is to convince the readers that especially today non‐life insurance is not only an exciting ground to apply existing modern statistical tools but also a fertile environment for new and challenging statistical developments. The activities of an insurance company can be viewed as an industrial process where data management and data analysis play a key role. That is why a fundamental understanding of data‐related issues (such as data quality, variability, analysis and correct interpretation) is so essential to the insurance business. These are exactly the tasks where professional statisticians excel. Also, a better understanding of the field of general insurance by statisticians will promote fruitful exchanges between actuaries and statisticians, thereby helping to bring actuarial and statistical professional societies closer to each other. Selected examples are used to cover the essential aspects of general insurance, and all of them are based on the author's experience. The paper concludes with some remarks on the role of statisticians working in general insurance. 相似文献

In this paper, I analyze optimal insurance against unemployment and disability in a private information economy with endogenous health and search effort. Individuals can reduce the probability of becoming disabled by exerting prevention effort. I show that the optimal sequence of consumption is increasing for a working individual and constant for a disabled individual. During unemployment, decreasing benefits are not necessarily optimal. The prevention constraint implies increasing benefits while the search constraint demands decreasing benefits while being unemployed. However, if individuals respond sufficiently to search incentives, the latter effect dominates the former and the optimal consumption sequence is decreasing during unemployment. 相似文献

AbstractLittle systematic research has investigated differences in expressed attitude as a function of the manner in which probability information is communicated to a decision maker. The purpose of this paper is to investigate differences in expressed attitude when insurance coverage is introduced in a known-risk situation (the probability of loss is known), an uncertain situation (there is no prior information on the probability of loss) or an ambiguous (the information provided is vague). The experiments reported in this paper have been developed and tested in the classroom with undergraduate students. Unlike the vast majority of previous work dealing with lotteries and laboratory gambles, this study examine the behavior of people when facing a purchase decision on a well-known consumer good, i.e. a bottle of wine. The comparative results provide some evidence on the risk-taking behavior of consumers for small losses. Within an insurance context, people prefer the more familiar option of a known-risk situation and contrary to expectations, the results do not provide support to ambiguity aversion but to ambiguity seeking. 相似文献

AbstractUsing a hand-collected dataset, we examine share trading activity over the period 1882–1920 for the North British and Mercantile Insurance Company, one of the largest UK companies of the time. Our main finding is that the steady flow of rentiers into the shareholding constituency of this company stymied share trading activity. Another important finding is that share trading still occurred during the closure of the stock exchange in 1914, but on a much-reduced scale. We also find that there was a substantial boom in share trading and in insurance stock prices after World War I. 相似文献

Bernard, He, Yan, and Zhou (Mathematical Finance, 25(1), 154–186) studied an optimal insurance design problem where an individual's preference is of the rank‐dependent utility (RDU) type, and show that in general an optimal contract covers both large and small losses. However, their results suffer from the unrealistic assumption that the random loss has no atom, as well as a problem of moral hazard that provides incentives for the insured to falsely report the actual loss. This paper addresses these setbacks by removing the nonatomic assumption, and by exogenously imposing the “incentive compatibility” constraint that both indemnity function and insured's retention function are increasing with respect to the loss. We characterize the optimal solutions via calculus of variations, and then apply the result to obtain explicitly expressed contracts for problems with Yaari's dual criterion and general RDU. Finally, we use numerical examples to compare the results between ours and Bernard et al. 相似文献

The constant proportion portfolio insurance (CPPI) strategy is one of the most popular asset allocation strategies employed by guaranteed-return financial products investors. Rebalance disciplines play an important role in determining the CPPI performance in practice. This paper examines whether the selection of rebalance rules affects CPPI strategy performance in the context of Chinese equity markets and, if so, in what pattern, and whether an optimal parameter of rebalance exists. We find that, (1) the three alternative rebalance disciplines – time discipline, market move discipline and lag discipline – are indifferent in affecting the performance of CPPI strategy; (2) in terms of optimal parameters of each rebalance rule, the optimal rebalancing period for the time discipline is 3 trading days, the optimal trading threshold of the market move discipline 4%, and the optimal lag factor of the lag discipline 6%. These optimal parameters are not influenced by the length of investment. 相似文献
