This paper provides a unified treatment of externalities associated with fertility and human capital accumulation as they relate to pension systems. It considers as overlapping generations model in which every generation consists of high earners and low earners with the proportion of types being...

There exists a wide variety of tax treatments of pensions across the world. And the reasons for such a range of regimes are not clear. This note reviews the general principles of pension taxes and analyses the theoretical foundations of why pension incomes ought to be taxed specifically. To do...

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that when...

We consider both theoretically and empirically the effect of unemployment insurance (UI) on precautionary savings behavior. Simulations of a stochastic life cycle model suggest that increasing the generosity of UI will substantially lower the asset holdings of the median worker, and that this...

We study the design of pension benefits for male and female workers. Women live longer than men but have a lower wage. Individuals can be single or live in couples who pool their incomes. Social welfare is utilitarian but an increasing concave transformation of individuals' lifetime utilities...

This paper investigates whether exchanging the Social Security delayed retirement credit (currently paid as an increase in lifetime annuity benefits) for a lump sum would induce later claiming and additional work. We show that people would voluntarily claim about half a year later if the lump...

This paper assesses the impact of variable investment-linked deferred annuities (VILDAs) on lifecycle consumption, saving, and portfolio allocation patterns given stochastic and systematic mortality. Insurers have taken two approaches to manage systematic mortality risks, namely self-insurance...

This paper examines how labor income volatility and social security benefits can influence lifecycle household portfolios. We examine how much the individual optimally saves and where, taking into account liquid financial wealth and annuities, and stocks as well as bonds. Higher labor income...

A large international literature has documented the labor market distortions associated with social security benefits for near-retirees. In this paper, we investigate the 'other side' of social security programs, seeking to document improvements in wellbeing arising from the provision of public...

The single most important long run fiscal issue facing the developed world is the aging of its populations. In virtually every developed country, there will be a steep increase in the ratio of the elderly to the working age population over the first half of the 21st century. The purpose of our...
