Auswirkungen von Enhanced Annuities auf den Bestand eines Versicherers

The value for money of a standard annuity is the higher, the longer the life expectancy of an insured, and therefore it is only acceptable for persons with an above average life expectancy. The discrepancy is intensified by tax regulations that favor lifelong annuity payments opposed to a lump sum. This discrimination of impaired insureds could be prevented if so-called enhanced annuities were offered, i.e. products where the annuity paid is the larger, the lower the person’s life expectancy. The article presents a quantitative comparison of the risk profile of insurance companies offering standard annuity contracts compared to enhanced annuities and an analysis of the impact of adverse selection on a standard insurer. By definition of individual mortality rates a heterogeneous insurance portfolio is specified. Besides we model the individual underwriting of enhanced annuities. A Monte Carlo Simulation provides results to compare the profit/loss situation of a portfolio of traditional annuity products and a portfolio of enhanced annuities with individual underwriting of different quality and to assess the impact of selection effects.     

On the Cost of Adverse Selection in Individual Annuity Markets: Evidence From Singapore

New evidence is presented on the cost of adverse selection in individual annuity markets using Singapore data. The Singapore annuity market is an interesting setting to examine the cost of adverse selection for three reasons. First, unlike many Western countries, the Singapore government provides very limited public financial assistance for retirees. Second, while social security contributions mandated under the Central Provident Fund (CPF) result in a high forced savings rate, a large proportion of CPF savings, are used up for housing. Third, to ensure that retirees have sufficient funds to meet basic needs, individuals who reach age 55 are required to set aside a minimum amount of their CPF savings, which can be withdrawn at age 62. The CPF Board allows various options for investing the minimum sum, but the most attractive option is to purchase an annuity. The institutional setting in Singapore in effect provides insurers with a large captive market for annuities. It is conjectured that this should be reflected in a significantly lower cost of adverse selection for annuities sold in Singapore as compared with other countries. The results herein, using data for CPF‐approved insurers, are strongly consistent with this conjecture. On average, money's worth of annuities is higher than annuities sold to a similar age‐gender mix in the United States, United Kingdom, and Australia. Adverse selection accounts for less than 13 percent of the cost of longevity insurance compared to 30–50 per‐ cent documented in many previous studies. These results suggest that one way to resolve the adverse selection problem is to adopt a universal individual defined contribution pension scheme that mandates or provides strong incentives for retirees to purchase annuities.     

Who Benefits from the Reform of Pension Taxation in Germany?*

The present paper quantifies the revenue, distributional and efficiency effects of the recent reform of pension taxation in Germany. The starting point is the new legislation, which has introduced a switch to the deferred taxation of retirement benefits starting in 2005. We compare this reform with an alternative transition proposed by the Federation of German Pension Insurance Institutes (VDR), where double taxation is avoided at the cost of higher revenue losses. Our simulations indicate significant growth and efficiency gains from the new tax legislation. Winners from the reform are mainly younger workers, while older workers, civil servants and the self‐employed will lose. The VDR proposal would have resulted in higher efficiency gains, but also in stronger distributional consequences.     

Interest Income Tax Evasion,the EU Savings Directive and Capital Market Effects*

The EU Savings Directive has been celebrated as a major political breakthrough in coordinating taxation in Europe. Against this background, the present paper evaluates the real‐world effects of this directive. The directive has left a loophole by providing grandfathering (exemption from withholding tax) for some securities. In this paper, we compare the pre‐tax returns of exempt bonds and comparable taxable bonds. If working around the Savings Directive is difficult for income tax evaders in Europe, then investors should be willing to pay a premium for bonds that are exempt from the withholding rate. Conversely, if such a premium is absent, then this suggests that the supply of existing loopholes (exempt bonds included) is large enough to allow tax evaders to continue evasion at no additional cost. The findings of our study are in line with this latter interpretation.     

应税消费品的界定、识别与调整——基于法律、技术与政治互动的税收逻辑

当前,我国消费税制改革与立法一体化工作的关键问题在于应税消费品的法治选择,该过程表现为立法框定、技术识别与政治调整的互动逻辑。在立法层面,针对现有应税消费品概念的语义抽象性,有必要在分析选择课税理论、梳理历史变迁的基础上,完成应税消费品概念的法律化和内涵化;在技术层面,基于典型税案中所暴露出的问题,应从形式和实质维度强化法律规则与技术标准的衔接;在政治层面,应从税制改革与税收法定的协调性、功能明晰与税目重构的关联性、选择课税与政治决策的程序化方面着力。     

Deferred Shareholder Taxation – Implementing a Neutral Business Tax in the European Union

This paper proposes the replacement of the corporate income tax by shareholder-based capital income taxation. Our proposal would guarantee investment neutrality of taxation and reduced tax compliance costs. The proposal is based on the S-base cash flow tax. Under the S-base tax, transactions within the corporate sector are not taxable and only transactions between shareholders and corporations are subject to tax. In contrast to existing S-base cash flow tax systems, tax deductibility of investments is deferred. Rather, the acquisition costs and capital endowments are compounded at the capital market rate and are set off against future capital gains. Dividends and withdrawals are fully taxable at the shareholder level. Because of the deferral of the tax payments our proposal is called ‘Deferred Shareholder Tax’ (DST). The DST exhibits the same neutrality properties as the traditional cash flow tax. Moreover, the compounded inter-temporal credit method ensures that it is neutral with respect to the decision between domestic and foreign investment. To increase acceptance of the DST, current taxpayers’ documentation requirements will be reduced rather than extended. Our proposal could be realised in a single EU country or in all member states of the EU.     

Asymmetric Information, Long-Term Care Insurance, and Annuities: The Case for Bundled Contracts

This article examines the markets for long-term care insurance and annuities when there is asymmetric information and there are costs of administering contracts. Individuals differ in terms of their risk aversion. Risk-averse individuals take more care of their health and are relatively high risk in the annuities market and relatively low risk in the long-term care insurance market. In the long-term care insurance market, both separating and partial-pooling equilibria are possible. However, in the stand-alone annuity market, only separating equilibria are possible. We show, consistent with the extant empirical research, that in the presence of administration costs the more risk-averse individuals may buy relatively more long-term care insurance and more annuity coverage. Under the same assumptions, we show that equilibria exist with bundled contracts that Pareto dominate the outcomes with stand-alone contracts and are robust to competition from stand-alone contracts. The remaining empirical puzzle is to explain why bundled contracts are such a small share of the voluntary annuity market.     

Dynamic portfolio choice with deferred annuities

We derive the optimal life-cycle portfolio choice and consumption pattern for households facing uncertain labor income, risky capital market, and mortality risk. In addition to stocks and bonds, the households have access to deferred annuities. Deferred payout life annuities are financial contracts providing life-long income to the annuitant after a specified period of time conditional on survival. We find that deferred annuities play an important role in household portfolios and generate significant welfare gains. Households with high benefits from state pensions, moderate risk aversion and moderate labor income risk purchase deferred annuities from age 40 and gradually increase their portfolio share. At retirement, deferred annuities account for 78% of total financial wealth. Households with low state pensions and high labor income risk purchase more annuities and earlier. Uncertainty with respect to future mortality rates has the same effect, i.e. household hedge against longevity risks using deferred annuities.     

Mortality-Indexed Annuities Managing Longevity Risk Via Product Design

Abstract

Longevity risk has become a major challenge for governments, individuals, and annuity providers in most countries. In its aggregate form, the systematic risk of changes to general mortality patterns, it has the potential for causing large cumulative losses for insurers. Since obvious risk management tools, such as (re)insurance or hedging, are less suited for managing an annuity provider’s exposure to this risk, we propose a type of life annuity with benefits contingent on actual mortality experience.

Similar adaptations to conventional product design exist with investment-linked annuities, and a role model for long-term contracts contingent on actual cost experience can be found in German private health insurance. By effectively sharing systematic longevity risk with policyholders, insurers may avoid cumulative losses.

Policyholders also gain in comparison with a comparable conventional annuity product: Using a Monte Carlo simulation, we identify a significant upside potential for policyholders while downside risk is limited.     

Valuation of Equity-Linked Insurance and Annuity Products with Binomial Models

Abstract

In this paper we develop a valuation method for equity-linked insurance products. We assume that the premium information of term life insurances, pure endowment insurances, and endowment insurances at all maturities is obtainable within a company or from the insurance market. Using a method similar to that of Jarrow and Turnbull (1995), we derive three martingale probability measures associated with these basic insurance products. These measures are agedependent, include an adjustment for the mortality risk, and reproduce the premiums of the respective insurance products. We then extend the martingale measures to include the financial market information using copulas and use them to evaluate equity-linked insurance contracts and equity-indexed annuities in particular. This is different from the traditional approach under which diversification of mortality risk is assumed. A detailed numerical analysis is performed for various existing equity-indexed annuities in the North American market.     

Longevity Risk Management in Singapore's National Pension System

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.     

Distinguishing closely held companies for taxation purposes: The Australian experience 1930-1972

Early in the life of Australia's income tax, the government, sensitive to loss of taxation revenue through artificial arrangements to divert taxable profits from individuals to companies where they would be taxed more lightly, saw fit to provide a special taxation regime for closely held companies. From the first attempts by the government to distinguish closely held companies for tax purposes in 1930, until the final legislative changes in 1972, there arose a highly unsatisfactory situation in which taxpayers sought, through increasingly artificial means, to subvert the legislative purpose with the aim of tax avoidance. The government's response throughout was inadequate in a number of respects, and fuelled the fires of tax avoidance through inept drafting of the relevant legislation and delayed treatment of perceived abuses by taxpayers.     

Enhanced Annuities – Produktinnovation als Lösungsstrategie für das Annuity Puzzle?

The private annuity markets are traditionally small even though annuity products have many favorable properties from a theoretical point of view. In this paper, the discussed approaches to the so-called annuity puzzle are examined and evaluated. In particular, adverse selection has been repeatedly held responsible for the annuity puzzle. Thus, it is investigated if enhanced annuities can eliminate or reduce problems on the annuity markets caused by adverse selection. It is shown by a modeling approach that – depending on the superior knowledge of the insured – a first-best-solution can be implemented by offering enhanced annuities.     

Annuity Markets and Retirement Security

The growing importance of defined contribution pension arrangements has drawn increased attention to the means by which retired people draw down their assets. Current UK law requires annuitisation of at least a fraction of defined contribution plan accumulations. Annuity markets have recently attracted some criticism with respect to pricing and the available range of product options. This paper describes a key feature of voluntary annuity markets: the presence of ‘adverse selection’. This is the tendency of annuitants to live longer than non‐annuitants, since individuals who know that they are likely to die soon do not purchase annuities. The paper presents information that quantifies the importance of adverse selection in the setting of private annuity prices and discusses the role of compulsory annuitisation requirements in reducing it. Requiring individuals to participate in the annuity market can reduce selection effects, at the cost of reducing individuals' range of retirement income options.     

美国税收递延型企业年金分析及对我国的启示

随着人口老龄化日趋严重,税收递延企业年金已成为各界关注的焦点。以美国税收递延企业年金为研究对象,运用序数效用理论和消费者均衡,结合风险因子、工资、缴费期限等因素,分析其微观经济效应;进而根据美国的所得税率,测量各模式的收入积累效应,以及对工资、投资收益、缴费参数进行敏感性分析,对比度量各参数值对个人积累值的影响。结果显示：美国现行的免除企业和个人所得税的 EET 税延方式是最优的,参加税延型企业年金计划可增加个人积累;缴费年限对退休后积累值的敏感性最高,投资收益率、工资依次次之,缴费率不敏感。由此,结合我国情况建议采取 EET 模式,延长缴费年限,降低门槛和放宽投资,建立法律审查机制。     

Impact of Flexible Periodic Premiums on Variable Annuity Guarantees

In this article, we study the fair fee of a flexible premium variable annuity (FPVA), in which the policyholder can choose to pay periodic premiums during the accumulation phase instead of a single initial premium. We are able to express fair fees using a fast and accurate approximation based on bounds on the price of the FPVA. We identify scenarios that are particularly costly for the insurer. Our study could help insurers estimate the magnitude of typical underpricing when offering flexible-premium variable annuities with the same fee as the corresponding single-premium variable annuity.     

Converting retirement benefit into a life care annuity with graded benefits*

This paper deals with life care annuities, i.e. bundled products comprising a life annuity and long-term care insurance. It aims to assess the cost of converting retirement benefit into a life care annuity with graded benefits using a pre-existing public pay-as-you-go pension scheme. With this objective in mind, we present an actuarial method based on array calculus for valuing this type of life care annuity. The health dynamics of the annuitant rely on a reversible illness-death multistate framework. The paper contains a numerical example in which mortality and disability assumptions are based on data from the USA and Australia, although this should be viewed simply as an illustration. In addition, in order to check the coherence of these data, we compute life expectancy for both healthy and dependent persons, and then for dependent persons in each of the states of dependence. The effect of ruling out the recovery assumption on the annuity’s cost is also assessed. The analysis provides valuable insights into how much it would cost to introduce these annuities and enables us to make some policy recommendations to help ensure that this combined pension scheme has a good actuarial design.     

养老保险税制的国际实践及启示

当前我国养老保险税制存在企业缴纳基本养老保险的税收优惠力度不够。企业年金税收政策不全面,个人储蓄性养老保险税制缺位,养老保险的税收监督政策不完美等问题。从国际比较角度看,鼓励性的养老保险税收政策总体上有利于扩大养老保险规模。因此。当前我国有必要加大企业缴纳基本养老保险的税收优惠力度,建立有利于调动个人建立企业年金和储蓄性养老保险的税制,同时,避免过度滥用税收优惠政策。     

Accounting and taxation: Conjoined twins or separate siblings?

This paper explores the relationship between accounting and taxation through the recent proposals for curbing corporate tax avoidance advanced by the Organisation for Economic Co-operation and Development (OECD) and the European Union (EU). The OECD is content to tweak pricing and fails to address the faultlines of accounting. The EU is promoting ‘unitary taxation’ and advocates a major reform of the way taxable profits are to be calculated. As IFRSs have reduced the usefulness of accounting numbers for taxation purposes, the EU has sought to recalibrate basic elements of accounting. This has considerable implications for the development of accounting.     

Fixed and variable longevity income annuities in defined contribution plans: Optimal retirement portfolios taking social security into account

This paper investigates retirees' optimal purchases of fixed and variable longevity income annuities using their defined contribution (DC) plan assets and given their expected social security benefits. As an alternative, we also evaluate using plan assets to boost social security benefits through delayed claiming. Using a calibrated life-cycle model, we determine that including deferred income annuities in DC accounts is welfare-enhancing for all sex/education groups examined. We also show that providing access to well-designed variable deferred annuities with some equity exposure further enhances retiree well-being, compared to having access only to fixed annuities. Nevertheless, for those facing the highest mortality rates, delaying claiming social security is mostly preferred, whereas those anticipating living longer than average will benefit more from using accumulated DC plan assets to purchase deferred annuities.
