Publication: On the Financial Sustainability of Earnings-Related Pension Schemes with 'Pay-as-You-Go' Financing and the Role of Government-Indexed Bonds
Abstract
In this paper we reconsider the idea of an earnings-related pension system with reserves invested in indexed government bonds as a mechanism to both ensure financial sustainability and improve security. The paper starts by reviewing the characterization of the sustainable rate of return of an earnings-related pension system with pay-as-you-go financing. We show that current proxies for the sustainable rate, including the Swedish 'gyroscope', are not stable and propose an alternative measure that depends on the growth of the buffer-stock and the pay-as-you-go asset. Using a simple one-sector macroeconomic model that embeds a notional account pension system we then show how GDP-indexed government bonds, if combined with the right measure for the sustainable rate of return on contributions, could be used to generate a sustainable and secure earnings-related pension system, without becoming a fiscal burden. The proposal is particularly attractive for countries considering reforms to earnings-related systems that have accumulated a large implicit pension debt. In this case, the government bonds allow the financing of this debt in a transparent way. The proposed mechanism can also facilitate the transition to a fully funded pension system when the government bonds are allowed to be traded.

Publication On the Financial Sustainability of Earnings-Related Pension Schemes with “Pay-As-You-Go” Financing and the Role of Government Indexed Bonds(World Bank, Washington, DC, 2006-07)In this paper the authors reconsider the idea of an earnings-related pension system with reserves invested in indexed government bonds as a mechanism to both ensure financial sustainability and improve security. They start by reviewing the characterization of the sustainable rate of return of an earnings-related pension system with pay-as-you-go financing. The authors show that current proxies for the sustainable rate, including the Swedish "gyroscope," are not stable and propose an alternative measure that depends on the growth of the buffer-stock and the pay-as-you-go asset. Using a simple one-sector macroeconomic model that embeds a notional account pension system they then show how GDP indexed government bonds, if combined with the right measure for the sustainable rate of return on contributions, could be used to generate a sustainable and secure earnings-related pension system, without becoming a fiscal burden. The proposal is particularly attractive for countries considering reforms to earnings-related systems that have accumulated a large implicit pension debt. In this case, the government bonds allow the financing of this debt in a transparent way.

In particular, it is well known that defined benefit pension schemes, which are not actuarially fair, can create incentives for early retirement and therefore reduce labor supply and the stock of human capital in a given country. This is an important policy issue in middle-income countries, with still low participation rates in the labor force, where the "window" opened by the demographic transition is already closed or will close in the near future. In these countries, policies to stimulate private sector growth, competitiveness, and employment creation should be accompanied by policies that increase labor force participation, raising the ratio of active to inactive population and therefore the potential for higher income per capita growth. Unfortunately, the analytical tools developed to assess pension reform options tend to focus on the financial sustainability of the schemes and the adequacy of benefits. Little attention is given in practice to the social costs imposed by distortions on the supply of labor. In part, this is given by the lack of analytical tools that, in the context of limited information regarding individual preferences and behavior, can be used to assess the magnitude of these distortions. This paper develops methodologies that can bridge the gap between economic theory and the practices of pension policy personnel under conditions of deep uncertainty regarding the variables driving individual behavioral responses to policy changes. First, the paper develops an indicator to predict the age-specific retirement probabilities induced by a particular pension system, given heterogeneous individual preferences over risk, consumption, and leisure. The paper then describes how this indicator can be used to project the size of the labor force by gender, age and skill level and therefore the dynamics of human capital accumulation. The integration of these two analytical tools allow us to show the impact of a particular pension reform proposals on the dynamics of labor supply, human capital and, given the dynamics of capital and total factor productivity, economic growth. Furthermore, the paper develops a set of life-cycle income measures for typical individual paths that allow us to measure the contribution of segmented pension schemes to the segmentation of the labor market. The methods are applied to the case of Morocco.Publication Closing the Coverage Gap : The Role of Social Pensions and Other Retirement Income Transfers(World Bank, 2009)The book has four specific objectives: (a) to discuss the role of retirement income transfers in the context of a strategy for expanding old- age income security and preventing poverty among the elderly; (b) to take stock of international experience with the design and implementation of these programs; (c) to identify key policy issues that need to receive attention during the design and implementation phases; and (d) to offer some preliminary policy recommendations and propose next steps. The chapter one discusses the rationale for retirement income transfers. The main justifications are the limited coverage of the mandatory pension systems (chapter two) and the risk of poverty during old age (chapter three). Chapter four then examines the rights, based approach to expansion of social security coverage based on the conventions and recommendations of the International Labor Organization (ILO). The middle part of the book deals with international experience. Chapters five, six, and seven reviews selected programs in low-income, middle-income, and high-income countries, respectively, and chapters eight and nine discuss in greater depth the cases of Japan and the Republic of Korea. The five concluding chapters are concerned with policy issues as related to design. Chapter ten presents a typology of retirement income transfers and analyzes the potential economic impacts of the programs. Chapter eleven deals with financing mechanisms and the problem of allocative efficiency, given limited resources. Chapter twelve addresses two key issues related to institutional arrangements and targeting systems: Should countries consider separate programs to target the elderly poor instead of using the general social assistance system to target all poor? And, how can current proxy means-test systems be adapted to target the elderly poor? Chapter thirteen explores in more detail the links between social pensions and matching contributions in the context of a general strategy for expanding coverage. Finally, chapter fourteen provides guidelines for the design of the administrative systems needed to operationalize the various programs. The remainder of this overview summarizes the main messages from the subsequent chapters and outlines an agenda for future research and policy analysis. For clarity, it starts by presenting some definitions pertinent to the retirement income transfers discussed in the book.Publication Nonfinancial Defined Contribution Pension Schemes in a Changing Pension World : Volume 1. Progress, Lessons, and Implementation(Washington, DC: World Bank, 2012)Pensions and social insurance programs are an integral part of any social protection system. Their dual objectives are to prevent a sharp decline in income and protect against poverty resulting from old age, disability, or death. The critical role of pensions for protection, prevention, and promotion was reiterated and expanded in the new World Bank 2012-2022 social protection strategy. This new strategy reviews the success and challenges of the past decade or more, during which time the World Bank became a main player in the area of pensions. But more importantly, the strategy takes the three key objectives for pensions under the World Bank's conceptual framework coverage, adequacy, and sustainability and asks how these objectives and the inevitable difficult balance between them can best be achieved. The ongoing focus on closing the coverage gap with social pensions and the new outreach to explore the role of matching contributions to address coverage and/or adequacy is part of this strategy. This comprehensive anthology on nonfinancial defined contribution (NDC) pension schemes is part and parcel of the effort to explore and document the working of this new system or reform option and its ability to balance these three key objectives. This innovative, unfunded individual accounts scheme provides a promising option at a time when the world seems locked into a stalemate between piecemeal reform of ailing traditional defined benefit plans or their replacement with prefunded financial account schemes. The current financial crisis, with its focus on sovereign debt, has enhanced the attraction of NDC as a pension scheme that aims for intra and intergenerational fairness, offers a transparent framework to distribute economic and demographic risks, and, if well designed, promises long-term financial stability. Supplemented with a basic minimum pension guarantee, explicit noncontributory rights, and a funded pillar, the NDC approach provides an efficient framework for addressing poverty and risk diversification concerns.Publication The Financial Crisis and Mandatory Pension Systems in Developing Countries : Short-and Medium-Term Responses for Retirement Income Systems(World Bank, Washington, DC, 2008-12)The international financial crisis has severely affected the value of pension fund assets worldwide. The unfolding global recession will also impose pressures on public pension schemes financed on a pay-as-you-go basis, while limiting the capacity of governments to mitigate both of theses effects. Governments are reacting to these events in different ways. Some are asking whether the balance between funded defined-contribution and unfunded pension schemes should be reconsidered. A few have already taken actions to reverse prior reforms. This note discusses the potential impacts of the financial crisis on fully funded and pay-as-you-go retirement-income systems in World Bank client countries, and identifies key short-and medium-term policy responses.
