An employer that sets up a defined benefit pension plan promises to periodically pay a certain sum to each participant starting at some future date and continuing until death. Although both the future beneficiary and the employer can be asked to finance the plan throughout the beneficiary's career, any shortcoming of funds in the future is often the employer's responsibility. It is therefore essential for the employer to be able to predict with a high degree of confidence the total amount that will be required to cover its future pension obligations. Applying mortality forecasting models to the case of the Royal Canadian Mounted Police pension plan, we illustrate the importance of mortality forecasting to value a pension fund's actuarial liabilities. As future survival rates are uncertain, pensioners may live longer than expected. We find that such longevity risk represents approximately 2.8 percent of the total liability ascribable to retired pensioners (as measured by the relative value at risk at the 95th percentile) and 2.5 percent of the total liabilities ascribable to current regular contributors. Longevity risk compounds the model risk associated with not knowing what is the true mortality model, and we estimate that model risk represents approximately 3.2 percent of total liabilities. The compounded longevity risk therefore represents almost 6 percent of the pension plan's total liabilities. 相似文献

Although annuities are a theoretically appealing way to manage longevity risk, in the real world relatively few consumers purchase them at retirement. To counteract the possibility of retirees outliving their assets, Singapore's Central Provident Fund, a national defined contribution pension scheme, has recently mandated annuitization of workers’ retirement assets. More significantly, the government has entered the insurance market as a public‐sector provider for such annuities. This article evaluates the money's worth of life annuities and discusses the impact of the government mandate and its role as an annuity provider on the insurance market. 相似文献

Abstract In examining basis risk in index longevity hedges, it is important not to ignore the dependence between the population underlying the hedging instrument and the population being hedged. We consider four extensions to the Lee-Carter model that incorporate such dependence: Both populations are jointly driven by the same single time-varying index, the two populations are cointegrated, the populations depend on a common age factor, and there is an augmented common factor model in which a population-specific time-varying index is added to the common factor model with the property that it will tend toward a certain constant level over time. Using data from the female populations of Canada and the United States, we show the augmented common factor model is preferred in terms of both goodness-of-fit and ex post forecasting performance. This model is then used to quantify the basis risk in a longevity hedge of 65-year old Canadian females structured using a portfolio of q-forward contracts predicated on U.S. female population mortality. The hedge effectiveness is estimated at 56% on the basis of longevity value-at-risk and 81.61% on the basis of longevity risk reduction. 相似文献

Abstract This study investigates the risk inherent in defined contribution (DC) pension plans on an individual and aggregate basis, based on U.S. data. Our aim is to gain insight into the consequences of a DC pension scheme becoming the predominant pillar of retirement income for an entire society. Using the stochastic simulated output of a DC flexible age-of-retirement model, we first determine the optimal investment strategies. We then examine the demographic retirement dynamics of an entire population of DC pension plan participants. We observe that even for the most risk-averse plan members there is a high level of uncertainty in an individual’s age at retirement. At the aggregate population level, we find that this uncertainty does not get dampened to any great extent by a diversification effect. Instead, the central role played by the market in determining retirement dates results in significant variation in the dependency ratio (the ratio of retirees to workers) over time. In addition, an attempt to ameliorate the outcome by introducing additional realistic features in the DC population modeling did little to dampen this volatility, which suggests that countries dominated by DC schemes of this type may, over time, be exposed to significant risk in the size of its labor force. 相似文献

The book reserve system is the most widespread method of financing occupational pension plans in Germany. The pension liabilities are mutually insured by the Pensions-Sicherungs-Verein VVaG (PSVaG) against bankruptcy. The PSVaG recently stated that the insurance system needed to be reformed. In the future, risk-adjusted premiums as foreseen for the newly established Pension Protection Fund in the United Kingdom could become feasible. We perform a credit portfolio analysis to determine the risk profile of the PSVaG. The magnitude of a tail risk event suggests that under the current financing system it can only be smoothed out over decades. Under an expected loss pricing plan insurance premiums would vary greatly. In a marginal risk contribution approach the variation of the premiums would be less pronounced. 相似文献

Between 1992 and 1995, the Italian pension system was deeply reformed, and it is now moving from an earnings‐related to a contribution‐based scheme. The pre‐1992 system was generous and redistributive; however, often redistribution operated from the poor to the rich, notably because the benefit formula was based on the last years of earnings, thus benefiting workers with steep earnings profiles. The new contribution‐based scheme may enhance equity by removing (some of) the inequities implicit in the previous system. Simulations calibrated on Italian male employees show that the contribution‐based scheme reduces inequality among all groups considered, with the exception of college graduates employed in the private sector. When taking into account the average level of the benefit as well as its distribution, the analysis shows mixed results depending on the worker's number of years of contribution and on their retirement age, as well as on the steepness of their earnings profile. 相似文献

The Canadian banks have shown remarkable resilience to the financial crisis that intensified in the late 2008. The interesting question is whether this stability is due to their prudent lending practices to limit the original risk exposures or due to effective risk management through hedging by using financial derivatives. In this paper, we implement the option‐theoretic model of Merton to calculate the implied asset risk and discern the impact of these derivatives on the aggregate risk for Canadian banks over the period 1997–2008. An algorithm of iterative procedure is developed to impute asset value and risk from bank stock prices. Our estimates show that the risk for Canadian banks is low and even decreasing till the unfolding of the recent crises in 2008. Further analyses reveal that such low risks are not due to reliance on hedging, nor is it related to trading in derivatives, after disentangling the intertwined effects of hedging and trading. These results suggest that involvements in derivatives, in and of themselves, should not be blamed for causing the bank crises; rather, it is conservatism in controlling original risk exposures that remains fundamental for safeguarding a healthy financial system. 相似文献

缴费年限直接影响着养老保险基金的缴费积累与参保者的待遇水平。能够领取养老金的缴费年限由最低缴费年限和退休年龄框定,参保者在缴费年限上具有较大的自主选择权。本文根据城镇职工基本养老保险现行制度设计,运用保险精算方法,构建了基金支付风险精算模型,并依据该模型实证评估了缴费年限对养老保险基金支付风险的影响。研究结果表明:单方面提高最低缴费年限并不能降低基金支付风险,根本原因在于“长缴多得”的计发机制;退休年龄的延长确能降低基金的支付风险,“早缴费”、“长缴费”将是减少养老基金支付风险的重要举措,但需要辅之以最低缴费年限调整才能充分发挥延迟退休增收减支作用;同一退休年龄下,女性比男性获益程度更高,相应地对实现缴费与待遇平衡产生更大的负效应;缴费年限增加能够提高替代率,增强制度的保障功能;缴费比例降低以及退休后平均余命、城镇单位就业人员平均工资增长率、养老金增长率、个人账户记账利率以及平均缴费工资指数提高会增大基金支付风险。建议通过调整退休年龄辅之以最低缴费年限并进行参量调整以降低基金支付风险。 相似文献

经历了私有属性的养老金制度的前期发展以后,意大利建立了主导性的以职业分割的卑斯麦式的公共养老金体系。待遇和缴费层面上的权利义务不对等,经济人口发展的不利因素以及国内国际的政治金融多重压力促使意大利开始改革公共养老金体系,恢复公共财政的可持续发展。意大利的公共养老金改革不仅建立了待遇和缴费的对应关系,也扩大了养老金的福利融资渠道并鼓励了私有属性的公共体系外养老金制度的发展。另外,发展阶段针对非雇佣关系或自雇业者的公共养老金体系的非政府的管理方式在改革中得到了保留。发展与改革阶段的一系列举措深刻的影响和塑造了意大利公共养老金制度的现有功能和形态,对于正处在发展改革过程中各国的公共养老金制度建设也是重要的启示。 相似文献

We investigate the effects of health and life expectancy on tolerance of financial risk. Using a standard life-cycle model, we find that the effects of health and life expectancy on preferences over lifetime-income risk are theoretically ambiguous. However, risk tolerance is independent of health and life expectancy when utility takes one of the standard (harmonic absolute risk aversion) functional forms or when optimal consumption is constant over time. Our empirical results, using data from a stated-preference survey (n=2,795), suggest that financial risk tolerance is positively associated with both health and life expectancy; hence utility is not consistent with standard functional forms. 相似文献

In this article, we examine the so-called natural hedging approach for life insurers to internally manage their longevity risk exposure by adjusting their insurance portfolio. In particular, unlike the existing literature, we also consider a nonparametric mortality forecasting model that avoids the assumption that all mortality rates are driven by the same factor(s). Our primary finding is that higher order variations in mortality rates may considerably affect the performance of natural hedging. More precisely, although results based on a parametric single factor model—in line with the existing literature—imply that almost all longevity risk can be hedged, results are far less encouraging for the nonparametric mortality model. Our finding is supported by robustness tests based on alternative mortality models. 相似文献

作为老龄社会的重要风险,长寿风险专题研究是近20年来公共养老金领域、保险公司关注的热点。长寿风险引发的保险公司寿险产品定价高估和年金产品定价低估之间存在潜在的自然对冲效应。为了量化这种对冲效应的长期影响,本文基于构建的同时涵盖低龄、高龄和超高龄在内的整个生命跨度的全年龄人口动态死亡率模型,采用对冲弹性量化终身寿险与终身年金、两全保险与定期年金、递延寿险与递延年金三类保障型寿险产品和养老型年金产品对冲效应的动态演变,并通过敏感性分析扩展探讨利率变化对对冲效应的长期影响。研究发现,从单位寿险和年金产品组合的净对冲效应来看,由于保险公司的产品定价区分了性别差异,使得女性的对冲效应更明显,因而女性对应的产品组合中的长寿风险对保险公司的影响更不显著。作为系统性风险,利率风险和长寿风险也存在对冲,利率上升能抵消或对冲长寿风险的影响,低利率下长寿风险更显著。 相似文献

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. 相似文献

本文根据现行企业职工基本养老保险基金中央调剂制度的相关规定,利用2017年不同省份的历史数据,通过定量测算考察了不同中央调剂金比例对缩小养老保险基金地区差距的影响,并分别从“补缺口角度”和“公平角度”提出最优中央调剂金比例的设定原则。测算结果显示:中央调剂制度可以在短期内缩小不同省份之间的养老保险基金差距,缓解部分省份的养老金支出压力,但是随着中央调剂金比例的逐步上调,可能会出现新的不公平现象。本文建议中央调剂金比例控制在5%左右。 相似文献

This study focuses on the stock market impact of Japanese corporate decisions to adopt pension plans. Implementing corporate pension plans in Japan is complicated because they are heavily regulated by the government and the traditional lump‐sum‐only severance benefit plans already exist, requiring interfacing newly adopted plans with existing ones. Using the GARCH estimation method, the market model applied in this article for the relatively long period 1975–1995 yields evidence that suggests that the stock market responds to some of the more specific characteristics of adopted plans. Alternative specifications of the pension “event” also suggest that relatively little of the market impact comes from public announcements about pension adoption occasioned by the release of a firm's financial statement. 相似文献

We bring together three disparate strands of literature to develop a comprehensive empirical framework to examine the efficiency of security analysts' earnings forecasts in Singapore. We focus specifically on how the increased uncertainty and the negative market sentiment during the period of the Asian crisis affected the quality of earnings forecasts. While we find no evidence of inefficiencies in the pre-crisis period, our results suggest that after the onset of the crisis, analysts (1) issued forecasts that were systematically upward biased; (2) did not fully incorporate the (negative) earnings-related news; and (3) predicted earnings changes which proved too extreme. 相似文献
