The United States Social Security fund is huge and in trouble. The United Kingdom has experimented with the voluntary contracting out of pensions to the private sector. Chile has privatized its public pension system. Australia has adopted a means-tested public pension system. Japan has the earliest retirement age of any advanced economy; it also has the highest rate of labor force participation by elderly men. Can We Afford to Grow Older? provides a comprehensive, up-to-date survey of the implications of population aging in these and other OECD countries relative to a range of specific interrelated issues--Social Security schemes, employer pensions, educational attainment, wage growth and distribution, economic productivity, consumption, savings, retirement, and health care--all within a realistic framework for modeling and discussing policy. International in scope, filled with rich institutional detail, and built on a solid technical foundation, this will be a standard reference on the economic consequences of aging. Richard Disney adopts a "life-cycle" view of the world which recognizes that individuals often make plans with a forward-looking perspective across the stages of childhood, the peak of economic productivity, and retirement. He stresses the existence of overlapping generations and the reality of generational transactions (which include tax and transfer systems, bequests, and charity to the elderly). And he assumes intertemporal optimization as a useful unifying basis for analyzing social security, private pension schemes, lifetime labor-supply decisions, consumption, and saving. Among the surprising conclusions that emerge is that there is no "crisis of aging"--no adverse effect of aging on productivity. And although there are serious crises in pay-as-you-go social insurance programs and in health care, these have little to do with aging. Moreover, the shift in private provision plans away from traditional defined- benefit plans will continue, along with an interest in privatized pensions instead of social security.

This paper considers the evolution of the UK's pension programme in the light of various stated rationales for public intervention. It argues that the publicly-provided (tax-financed) pension programme has gone through four distinct stages since 1946. It examines some of the issues that have arisen in the context of private pension provision in the UK, both in the form of so-called 'defined benefit' and 'defined contribution' pension plans, as well as individual purchases of annuities.

The view that demographic ageing will lead to a growing welfare state has been questioned by Razin et al. [Razin, A., Sadka, E., Swagel, P., 2002. The aging population and the size of the welfare state. Journal of Political Economy 110, 900-918]. Their empirical analysis suggests that growing dependency is associated with a smaller welfare state. They construct a model of welfare provision with heterogeneous workers consistent with this 'puzzle'. I show here that their empirical 'puzzle' simply does not exist - both cross-tabulations and econometrics show that demographic ageing is associated with a larger welfare state. Moreover, worker heterogeneity does not affect the welfare state in the suggested manner. There is evidence that social security design matters when considering the effect of old age dependency on the size of the welfare state. [Copyright 2006 Elsevier B.V.]

I argue that the offsetting effect of public pension contributions on household retirement saving depends on how closely the public pension programme imitates a private retirement saving plan (i.e. the 'actuarial' content of the public pension programme) — the closer the design of the programme to a private retirement saving plan, the higher the offset. I estimate the determinants of household saving rates in a cross-country panel, augmenting standard measures of public pension programme generosity and cost by indicators that proxy the actuarial component of the programme. These indicators affect saving rates as predicted.
