One-Period Model of Individual Consumption, Life Insurance, and Investment Decisions 总被引:1,自引:0,他引:1
Yanyun Zhu 《The Journal of risk and insurance》2007,74(3):613-636
This article studies individuals' optimal decisions on consumption, life insurance, and stock purchases in a one‐period framework. With exponential utility functions, individuals' life insurance and stock purchases are independent of each other; life insurance purchases are affected only by individuals' future income, bequest intensity, risk attitude, survival probability, and the insurance risk premium; stock purchases are affected only by individuals' risk attitude, the risk‐free rate of return, the stock return, and stock volatility. With power utility functions, life insurance and stock purchases are positively related with each other and are affected by all the factors. 相似文献

This study measures the deposit insurance premium under stochastic interest rates for Taiwan's banks by applying the two-step maximum likelihood estimation method. The estimation results suggest that the current premiums—charging 5, 5.5, and 6 basis points per dollar of insured deposits—are too low, but largely reflect the rank orders of the risks of the insured banks. Moreover, the regression results indicate that asset volatility dominates bank size in determining the insurance premium. When the volatility risk is decomposed into two parts, credit risk significantly dominates interest-rate risk. An examination of bank characteristics indicates that privately owned old banks are more likely to have lower levels of credit risk, asset volatility, and deposit insurance premiums than state-owned banks and newly chartered banks. 相似文献

This article analyzes the economic functions of independent insurance intermediaries (brokers and independent agents), focusing on the commercial property–casualty insurance market. The article investigates the functions performed by intermediaries, the competitiveness of the market, the compensation arrangements for intermediaries, and the process by which policies are placed with insurers. Insurance intermediaries are essentially market makers who match the insurance needs of policyholders with insurers who have the capability of meeting those needs. Intermediary compensation comprises premium‐based commissions, expressed as a percentage of the premium paid, and contingent commissions based on the profitability, persistency, and/or volume of the business placed with the insurer. Empirical evidence is provided that premium‐based and contingent commissions are passed on to policyholders in the premium. However, contingent commissions can enhance competitive bidding by aligning the insurer's and the intermediary's interests. This alignment of interests gives insurers more confidence in the selection of risks and thus helps to break the “winner's curse” and encourages insurers to bid more aggressively. Independent intermediaries also help markets operate more efficiently by reducing the information asymmetries between insurers and buyers that can cause adverse selection. 相似文献

In recent years, farmers have had high participation rate in the rural social endowment insurance in China, for which personal contribution and government subsidy are the main funding source. There have been increasingly more farmers participating into the program. However, their enthusiasm for high premium payment was rather low as most of them selected the minimum premium for insurance. In this article, the discounted utility theory from behavioral economics was adopted to analyze insurance selection behaviors of farmers; in addition, a discounted incremental utility model with a hyperbolic discounting function was also further constructed to describe their insurance decision-making processes. Based on the investigation of time preferences of farmers, their insurance participation behaviors of diverse natures were simulated. The corresponding results indicated that active insurance participation and low insurance premium payment were rational choices for most farmers; in comparison, for the elders with higher income, different choices can be made. Therefore, policy makers could formulate differentiated subsidy policies directing at farmers from different groups, so as to stimulate their enthusiasm for premium payment. 相似文献

Although Mossin's Theorem (“full insurance with a fair premium and less‐than‐full coverage with a proportional premium loading”) is well known for the classes of coinsurance contracts and for deductible‐insurance contracts, it has not been proven for the class of upper‐limit insurance contracts. This article provides a proof for this case. 相似文献

Evidence is provided from changes in deposit insurance premiums in the early 1990s on the validity of the premium absorption hypothesis and the premium shifting hypothesis. Analysis of abnormal market returns associated with deposit insurance events using a market‐model event‐study methodology suggests that reductions in deposit insurance premiums are associated with increases in the market value of banking organizations; conversely, increases in deposit insurance premiums are associated with decreases in market wealth. The largest banks in the sample and banks with low equity capital (and low risk‐based capital ratios) appear to be most affected. These results are generally consistent with the premium absorption hypothesis but inconsistent with the premium shifting hypothesis. 相似文献

This article analyzes the problem of designing Pareto‐optimal insurance policies when both the insurer and the insured are risk averse and the premium is calculated as a function of the actuarial value of the insurer's risk. Two models are considered: in the first, the set of admissible policies is constrained by a given size of the premium; in the second, the premium size is not constrained so that it varies with the actuarial value of a policy chosen by the agents. For both cases a characterization of the Pareto‐optimal policies is derived. The corresponding optimality equations for the Pareto‐optimal policies are obtained and compared with the results on the classical risk exchange model. 相似文献

We find that the long‐term equity premium is consistent with both GDP growth and portfolio insurance. We use a supply‐side growth model and demonstrate that the arithmetic average stock market return and the returns on corporate assets and debt depend on GDP per capita growth. The implied equity premium matches the U.S. historical average over 1926–2001. Separately, we find that the equity premium tracks the value of a put option on the S&P 500. Our theory predicts a smaller equity premium in the future, assuming that the recent regime shifts in dividend policies, interest rates, and tax rates are permanent. 相似文献

养老保险基金主要由劳动者和企事业单位缴费形成,它是养老保险制度赖以建立的基础。养老保险逃费对这一基础起着极大的破坏作用。调查研究结果表明,我国的养老保险逃费问题比较突出,相当一部分应缴费单位和个人都存在逃费现象,逃费形式花样百出,它直接影响养老保险制度的正常运行和发展。逃费是经济发展水平和劳动者的收入状况、养老保险主体行为和养老保险制度本身多种因素共同作用的结果。克服养老保险逃费需要从多方面着手:努力发展经济,不断提高劳动者收入;改革养老保险管理制度;充分调动企业参加养老保险的积极性;提高劳动者参加养老保险的积极性;强化各级政府的责任;加强养老保险管理部门的责任。 相似文献

We examine the time‐series relation between aggregate bid‐ask spreads and conditional equity premium. We document that average marketwide relative effective bid‐ask spreads forecast aggregate market returns only when controlling for average idiosyncratic variance. This control allows us to document the otherwise elusive relation between illiquidity and returns. The reason is that idiosyncratic variance correlates positively with spreads but has a negative effect on conditional equity premium, causing an omitted variable bias. Our results are robust to standard return predictors, alternative illiquidity measures, and out‐of‐sample tests. These findings are important because they provide strong support for the literature's conjecture that marketwide liquidity is an important asset pricing risk factor. 相似文献

Economists, regulators, and consumer protection agencies have highlighted the welfare losses for consumers who purchase high‐load insurance against modest stakes risks. Mandatory information disclosure is a potentially attractive public policy tool that might improve consumers' choices, but has not been widely tested in insurance settings. We conduct an incentive‐compatible insurance demand experiment, in which we manipulate the information disclosed to subjects. We test whether any of the three most commonly suggested disclosures affect insurance demand, disclosing either (1) the true probability of loss, (2) the contract's expected loss, or (3) the insurer's profit on the transaction. Similar to consumers in naturally occurring insurance markets, subjects in the laboratory demonstrate significant demand for high‐load insurance against modest stakes. However, we find no effect of any of the three disclosure treatments on subjects' insurance choices. We discuss the implications of our results for possible public policy initiatives in insurance markets. 相似文献

D&O保险的立法问题是我国司法实践中一个亟需澄清的问题,同时亦是保险法学界关注较多的基础理论问题。本文通过考察D&O保险合同在公司治理中的价值,细致分析在2019年日本第二次《公司法》修改之际学界对D&O保险规则立法与否的争论及立法演进历程,并对增设D&O保险合同规定的初衷以及在决定该保险合同内容时的决策程序进行系统阐释。研究发现,增设D&O保险合同规定、明确公司有权全额负担保险费用,有助于提高管理层的风险承担水平和管理效率,进而促进企业创新。在探讨我国《公司法》是否应当构建D&O保险规则这一问题时,应注意到公司法上的补偿制度是D&O保险存在的前提。就D&O保险合同内容的信息披露问题,一方面,为防止公司费用无限地用于提升填补限额,可采披露D&O合同信息的手段;另一方面,就具体的信息披露事项,不可盲目“照搬”美国做法。 相似文献

This study analyzes the effect of premium rates on banks’ incentives to join a deposit insurance scheme and their incentives
to invest in risky projects under a voluntary deposit insurance scheme. We find that in order to maximize social welfare,
the insurance agency must either set the premium rate to be low so as to attract all banks to join the insurance scheme, or
not to have the deposit insurance at all. However, the low premium rate in the voluntary scheme does not balance the budget
of the deposit insurance. We also show that in the compulsory deposit insurance scheme, however, it is possible to impose
an optimal premium rate that can balance the insurance agency’s budget and achieve the highest social welfare. The results
also present the dominance of the compulsory scheme over the voluntary scheme in terms of maximizing social welfare and balancing
the budget.

Pratt [1964] establishes that a more risk-averse individual in the Arrow-Pratt sense has a higher compensating risk premium for full insurance, but no comparable result has been established for partial insurance. Ross [1981] shows that a more risk-averse individual in the Arrow-Pratt sense may not be willing to pay more for a reduction in risk in the sense of mean-preserving contraction. We show that a more risk-averse individual in the Arrow-Pratt sense has a higher compensating risk premium for all empirically relevant forms of partial insurance because they induce a reduction in risk in the stronger sense of Bickel and Lemann [1979].JEL Classification No.: D81 相似文献

We examine the effects of 9/11 on the insurance industry, hypothesizing a short‐run claim effect, resulting from insufficient premium ex ante for catastrophic losses, and a long‐run growth effect, resulting from ex post insurance supply reductions and risk updating. Following Yoon and Starks (1995) we use short‐ and long‐run abnormal forecast revisions to measure both effects, analyzing them as a function of firm‐specific characteristics. We find that firm type, loss estimates, reinsurance use, and tax position are important determinants of the short‐run position. Firm type, loss estimates, financial strength, underwriting risk, and reinsurance are key determinants of the firm's long‐run position. 相似文献
