The Value of Teachers' Pensions in England and Wales*

The paper examines in detail the value of pension provision to teachers in the public sector in England and Wales, comparing pension accrual under both the pre‐ and the post‐2007 schemes. We find that, at the median, pension accruals under the old scheme rules were worth 14.7 per cent of current salary to members, while if the new scheme rules were applied to all current members this would fall to 11.2 per cent. We find that this reduction in generosity is more than sufficient to offset the increase in generosity implied by rising life expectancies over the last quarter of a century. In addition, we show how the estimates depend on both the shape of the underlying age–earnings profile and the headline pay award. We find that the value of the new scheme rules to Teachers' Pension Scheme (TPS) members is similar to the value of the defined contribution pension offered to civil servants, but worth more than a simple, example, private sector defined contribution scheme.     

Correlation and the Pension Protection Fund*

In this paper, I use a stochastic approach to model the effect that correlations between pension scheme assets and firm values should have on the premiums chargeable by the Pension Protection Fund. In particular, I look at the effect on the aggregate premium that should be charged considering a representative universe of companies and their pension schemes. I find that ignoring the correlations, even if the volatility of pension scheme assets is allowed for, leads to potentially serious underestimation of the aggregate premium due.     

风险分散与中国混合型基本养老保险制度改革研究

本文从参保人养老投资风险分散角度研究混合型基本养老保险制度设计。通过构建一个两期消费模型,综合考虑参保人所面临的人口结构、工资增长率、养老基金投资等风险因素,本文研究了混合型基本养老保险制度中现收现付制与基金积累制的最优比例,并利用中国数据进行了测算与敏感性分析。研究发现:引入小规模个人账户基金积累制可以分散人口老龄化给现收现付制所带来的风险,中国实行混合型基本养老保险制度有其合理性;但如果要维持40%～45%的养老金替代率水平,中国基本养老保险制度的财务可持续性会面临较大挑战。     

Valuation of an early exercise defined benefit underpin hybrid pension

In this paper, we consider three types of embedded options in pension benefit design. The first is the Florida second election (FSE) option, which has been offered to public employees in the state of Florida since 2002. The state runs both defined contribution (DC) and defined benefit (DB) pension plans. Employees who initially join the DC plan have the option to convert to the (DB) plan at a time of their choosing. The cost of the switch is assessed in terms of the ABO (Accrued Benefit Obligation), which is the expected present value of the accrued DB pension at the time of the switch. If the ABO is greater than the DC account, the employee is required to fund the difference. The second is the DB Underpin option, also known as a ‘floor offset’ or a ‘Greater-of-benefit’ plan, under which the employee participates in a DC plan, but with a guaranteed minimum benefit based on a traditional DB formula. The third option can be considered a variation on each of the first two. We remove the requirement from the FSE option for employees to fund any shortfall at the switching date. The resulting plan is similar to the DB underpin, but with the possibility of early exercise. We adopt an arbitrage-free pricing methodology to value each option. We analyse and value the optimal switching strategy for the employee by constructing an exercise frontier, and we illustrate numerically the difference between the FSE, DB Underpin and Early Exercise DB Underpin options.     

Do Managers of U.S. Defined Benefit Pension Plan Sponsors Use Regulatory Freedom Strategically?

We use historical particularities of pension funding law to investigate whether managers of U.S. corporate defined benefit pension plan sponsors strategically use regulatory freedom to lower the reported value of pension liabilities, and hence required cash contributions. For some years, pension plans were required to estimate two liabilities—one with mandated discount rates and mortality assumptions, and another where these could be chosen freely. Using a sample of 11,963 plans, we find that the regulated liability exceeds the unregulated measure by 10% and the difference further increases for underfunded pension plans. Underfunded plans tend to assume substantially higher discount rates and lower life expectancy. The effect persists both in the cross‐section of plans and over time and it serves to reduce cash contributions. We further show that plan sponsor managers use the freed‐up cash for corporate investment and that credit risk is unlikely to explain the finding.

How the provision of inflation information affects pension contributions: A field experiment

Ignoring the effects of inflation in retirement planning can have severe consequences for an individual's future financial well-being. Yet, many pension funds do not communicate inflation-related information, presumably for the fear of reduced contributions once the members understand how low the “real” return on saving for retirement is. As an alternative prediction, the provision of inflation information could increase pension contributions, because it reveals possible pension shortfalls. In cooperation with a major German pension fund, we conduct a field experiment, in which we vary the inflation information provided to the fund members, to explore this important issue. Among all participants, we find mostly positive but insignificant effects of the inflation information on pension contributions. Among those participants who voluntarily changed their pension contributions after the experimental intervention, the provision of inflation information significantly raises the likelihood of increasing pension contributions.     

Pension Funding Regulations and Actuarial Gains and Losses

With pervasive pension funding deficits, Korean firms have been under pressure to improve their funding levels. We examine whether firms have incentives to set obligation‐decreasing pension assumptions when they have large pension deficits (pension obligations in excess of plan assets) and when they make insufficient contributions to external pension funds. We find that firms report larger actuarial gains (or smaller actuarial losses) associated with the remeasurement of pension liabilities when their pension funding ratio (the ratio of the fair value of plan assets to defined benefit obligations) is lower and when contributions to plan assets relative to pension service costs are smaller. Next, upon the introduction of a minimum pension funding guideline, we find that the effect of the funding ratio and contributions to pension funds on actuarial gains and losses is more pronounced for firms whose funding ratios are slightly below the minimum funding ratio than it is for firms whose funding ratios exceed or fall short of the minimum by a large margin. Our results indicate that firms opportunistically exercise discretion regarding corporate pension accounting under International Financial Reporting Standards to comply with pension funding regulations, thereby reducing perceived pension deficits.     

英国“第二支柱”职业养老金改革及其效果分析--以《2008年养老金法案》为例

20世纪70年代以来,随着人口老龄化的加剧和财政压力的加重,英国由国家养老金、职业养老金和个人养老金组成的三支柱养老保险体系的改革呈现出私有化的特点,尤其鼓励大力发展职业养老金和个人养老金计划。《2008年养老金法案》中关于英国职业养老金计划的改革具有划时代的意义,其中“国家职业储蓄信托”提升了职业养老金计划的整体投资绩效;“自动加入”机制作为职业养老金计划由自愿性转向强制性的标志,极大地提高了职业养老金计划的参与率和覆盖面、增加了职业养老金计划的储蓄额。可以说,《2008年养老金法案》对英国职业养老金计划的发展起到了非常大的推动作用。     

降低企业基本养老保险政策缴费率能促进年金发展吗?北大核心

构建有效的多层次养老保障体系是积极应对我国人口老龄化的重要举措。本文基于税收调查数据,利用政策缴费率的差异,识别企业基本养老保险缴费负担对企业年金发展的影响。研究发现,企业基本养老保险缴费负担抑制了企业年金发展,其中政策缴费率每提高1个百分点,企业建立年金的概率会下降0.29个百分点,年金缴费率会减少0.06个百分点。使用上市公司数据进行分析,基本结论依然成立。进一步分析表明,基本养老保险会通过利润分享渠道、缴费能力渠道和缴费动机渠道影响企业年金发展。此外,企业基本养老保险对年金的影响,在企业产品定价能力较弱或小规模企业中更大,也会随地区经济增速的差异而不同,且仅在非国有企业中显著存在。依据本文估计的结果可以推算,企业基本养老保险政策缴费率降低4个百分点,能使年金覆盖率增加1.2个百分点,这同目前5.7%的覆盖率相比,是一个较大幅度的提升,但也应注意到6.9%的覆盖率依然偏低,年金发展需要更为积极的支持政策。     

Public and Private Pension Spending: Principles,Practice and the Need for Reform

This paper surveys the issue of public spending on pensions. Drawing on evidence from systems around the world, but particularly in Britain, we outline the arguments for different types of public and private provision of pension income and consider how far they go towards meeting the objectives of pension provision. We discuss past trends in spending and look at future projections.     

The Influence of Culture on Pension Plans

It is widely recognized that culture is a dimension affecting a vast array of management and social choices. However, we know little about the effect of culture on choices that combine both business and social issues in an accounting setting. Employee benefit choices by managers reflect both the business choices of a firm in the selection and retention of employees and social choices in the type and extent of benefits provided to employees. The objective of this study is to investigate the extent to which culture affects employee benefits as manifested in pension plans. In a comparison of plans that differ according to the home country of the parent firm and are offered in the regulated environment of the United States, results indicate an effect of culture on pension plan choices. In particular, culture plays a role in determining the funding level percentage of the plan, employer contributions receivable, and revenues received or receivable from employers.     

Facing the Age Wave and Economic Policy: Fixing Public Pension Systems with Healthcare in the Wings*

There are two overriding problems faced by ageing societies. One is the financing of public pension (social security in US terms) programmes. The other is paying for healthcare. This paper considers the healthcare issue briefly, emphasising that the issue arises primarily because of advances in medical technology. Better medical technology will improve healthcare in the future, but more advanced technologies also cost more. The focus of the rest of the paper is on the public pension problem. The emphasis is on the early retirement incentives inherent in the provisions of most public pension programmes around the world, the reduction in the labour force participation of older people caused by these incentives, and the large fiscal implication of the inducement of older people to leave the labour force. These results are based on the Gruber–Wise ongoing international social security comparison project.     

Cash-Balance Plan Conversions: Evidence on Excise Taxes and Implicit Contracts

Firms that wish to switch from a traditional defined‐benefit pension plan to a defined‐contribution‐type plan have a choice between converting to a cash‐balance plan or replacing the defined‐benefit plan with a full‐fledged defined‐contribution plan. According to Ippolito and Thompson's (1999; Industrial Relations, 39: 228‐245) excise tax avoidance hypothesis, a number of firms have switched to cash‐balance plans because conversion allows the firm to avoid excise taxes on its excess pension assets. In contrast to existing studies, our evidence supports the excise tax avoidance hypothesis. Cash‐balance plan conversions also have been criticized for imposing pension losses on older employees. The implicit contract theory of pensions predicts that poorly performing firms would be the ones that would impose losses on employees. However, our evidence indicates that firms converting to cash‐balance plans typically are not poor performers.     

Pension Portfolio Choice and Peer Envy

I examine the effect of envy on the portfolio allocation of workers in a defined contribution (DC) pension plan. If a worker’s DC plan performs better than his co‐worker’s, he may gloat; on the other hand, if his DC plan performs worse, he may feel envy. I model anticipated envy when workers make portfolio allocations, and find that in equilibrium, workers will mimic their co‐worker’s allocation to eliminate the disutility from envy. This portfolio allocation is riskier than that of a worker who does not exhibit envy.     

Public capital, public pension, and growth

This paper constructs an endogenous growth model with overlapping generations, whose engine of economic growth is productive public capital. We investigate a public policy under which the government allocates tax revenue between investment in public capital accumulation and public pension provision. We show that increasing the share of spending on public pensions always reduces economic growth. However, we show numerically that public pension provision improves social welfare and there exists an optimal share of spending on public pension provision unless the value of the time discount factor of the government is sufficiently high. Moreover, we show that in an economy facing an aging population, an increase in social security provision for the old rather than an increase in public investment can be preferable from the viewpoint of social welfare.     

Risk and the public service manager

The Department of Social Security's discussion document on equalizing state pension age is examined and put in context. The authors conclude that it takes too narrow a view of the equality issue, and argue for a more radical reappraisal of state pension provision for the 21st century.

The Many Challenges of Pension Accounting

Accounting for defined benefit pension plans has long been a major issue in accounting. Standard‐setters are grappling with revisions to pension accounting standards, and much change has already occurred in the United Kingdom. This paper identifies and discusses most of the major issues that standard‐setters must confront in developing new approaches to financial reporting for pensions. Key issues concern how to report the impact of changes in assumptions, how to recognize pension costs on the balance sheet and income statement, and how to reconcile the differences between accountants' and actuaries' approaches to pensions. Current standards assume that accounting estimates are independent of actuarial assumptions, and yet require a direct comparison of the accounting liability with the pension plan assets, when in fact they are incompatible measures based on differing assumptions and differing methodologies. As well, accounting has been complicit in managers' wishes to hide the volatility inherent in a pension plan investment strategy that focuses on higher‐risk equities to fund estimated monetary liabilities that have been discounted at low‐risk interest rates. Drawing on studies and research done largely in Europe, this paper attempts to consolidate some of the current thinking on the topic and to propose some preferred approaches to dealing with the problems of pension accounting.     

Employers' accounting for pensions: A theoretical approach to financial accounting standards no. 87

The extensive disclosure mandated for defined benefit pension plans by FAS 87 resulted in part from the ongoing controversy concerning the nature of the pension plan obligation. Based on a review of the pension chapters of seven intermediate accounting texts, conflicting perspectives of the nature of the plan obligation have not been thoroughly and appropriately integrated in textbook discussions of FAS 87 reporting requirements.The objective of this article is to present a teaching method which interprets the reporting requirements of FAS 87 as a reconciliation of the conflicting perspectives concerning the pension obligations. Examples are provided demonstrating how FAS 87 reconciles the opposing perspectives in the basic financial statement presentation, and how the perspectives are useful in understanding the reporting requirements related to the minimum liability and actuarial gains and losses.
