What Rates of Productivity Growth Would Be Required to Offset the Effects of Population Aging? A Study of Twenty Industrialised Countries

By Frank T. Denton & Byron G. Spencer (McMaster University) A shift in population distribution toward older ages is underway in industrialised countries throughout the world and will continue well into the future. We provide a framework for isolating the pure effects of population aging on per capita GDP, employ the framework in calculations for twenty OECD countries, and derive the rates of productivity growth required to offset those effects. We consider also some labour-related changes that might provide offsets,...

We’ll Live to 100 – How Can We Afford It?

The challenges we face to provide our ageing societies with a financially secure retirement are well-known. In most countries around the world, standards of living and healthcare advancements are allowing people to live longer. This should be celebrated, but we should also consider the implications for the financial systems that have been designed to meet our retirement needs, which in many countries are already under severe strain. This report has been produced as part of the Forum’s Retirement Investment Systems...

Modeling Multi-State Health Transitions in China: A Generalized Linear Model with Time Trends

By Katja Hanewald, Han Li & Adam Wenqiang Shao (University of New South Wales) Rapid population aging in China has urged the need to understand health transitions of older Chinese to assist the development of social security programs and financial products aimed at funding long-term care. In this paper, we develop a new flexible approach to modeling health transitions in a multi-state Markov model that allows for age effects, time trends and age-time interactions. The model is implemented in the...

Long-Run Biological Interest Rate for Pay-as-You-Go Pensions in Advanced and Developing Countries

By Masahiro Nozaki (International Monetary Fund) How much of an internal rate of return would a sustainable pay-as-you-go pension system offer current and future generations equally? The answer is the sum of the Long-Run Biological Interest Rates (LBIR), the real-world equivalent of Samuelson's (1958) biological interest rate, and future productivity growth. Reflecting global population ageing, the median LBIR across 172 countries is as low as 1 percent per year. The LBIRs are particularly low in advanced countries, estimated to be...

Fiscal Challenges of Population Aging in Brazil

By Alfredo Cuevas, Izabela Karpowicz & Mauricio Soto (International Monetary Fund); Carlos Mulas-Granados (Government of the Kingdom of Spain)  In recent decades, population has been aging fast in Brazil while old age pensions and health related spending have increased. As the population ages, the spending trend threaten to reach unsustainable levels absent reforms. Increasing the retirement age is key, but by itself will not provide sufficient savings to close the pension system financing gap, and reforms reducing replacement rates are...

Interactions between Financial Incentives and Health in the Early Retirement Decision

By Pilar Garcia-Gomez & Eddy van Doorslaer (Erasmus University Rotterdam); Titus J. Galama (USC Center for Economic and Social Research) & Ángel López Nicolás (Universitat Pompeu Fabra) We present a theory of the relation between health and retirement that generates testable predictions regarding the interaction of health, wealth and financial incentives in retirement decisions. The theory predicts (i) that wealthier individuals (compared to poorer individuals) are more likely to retire for health reasons (affordability proposition), and (ii) that health problems...

Dangerous Flexibility – Retirement Reforms Reconsidered

By Axel H. Börsch-Supan, Tabea Bucher-Koenen, Vesile Kutlu-Koc & Nicolas Goll (Max Planck Society for the Advancement of the Sciences) Flexible retirement is supposed to increase labor supply of older workers without touching the third rail of pension politics, the highly unpopular increase of the retirement age. While this may have intuitive appeal, this paper shows that it might be wishful thinking. Economic theory tells us that flexible retirement policies can have a zero or positive effect on labor force...

The Importance of Social Security Benefits to the Income of the Aged Population

By Irena Dushi & Howard Iams (US Social Security Administration); Brad Trenkamp (Government of the United States of America) Social Security benefits comprise the most important source of income for people aged 65 and over. However, changes in the last decades in employer-provided pensions, Social Security program, and societal changes may have altered the composition of income sources among the elderly. Some researchers have argued that the Current Population Survey (CPS ASEC) doesn’t properly measure income from retirement accounts and...

The Impact of Social Pensions on Intergenerational Relationships: Comparative Evidence from China

By Xi Chen (Yale), Karen Eggleston (Stanford University) & Ang Sun Renmin University of China) China launched a new rural pension scheme (hereafter NRPS) for rural residents in 2009, now covering almost all counties with over 400 million people enrolled. This implementation of the largest social pension program in the world offers a unique setting for studying the economics of intergenerational relationships during development, given the rapidity of China's population aging, traditions of filial piety and co-residence, decreasing number of children,...
