Ageing puts a strain on most countries' pension systems; forecasts show them to be more or less unsustainable. Evidence from social choice research, theoretical as well as empirical, does not seem to offer a way out of the dilemma, as the median voter will resist a reform. Despite this, Sweden...

The Swedish pension reform of 1999-2003 provides an opportunity to study whether and how important economic incentives are for the timing of retirement. The new pension system provides a much closer link between contributions and benefits than the former system. I study whether the reform has...

The aging of the American population will be a critical public policy issue in the years ahead. This paper surveys the recent literature on the economics of aging, with a special emphasis on government spending on the aged. The U.S. Census Bureau projects that the proportion of the elderly in...

This paper looks at welfare reforms in Italy and their effects on labour supply. I focus on social security reforms, which have taken place in the 1990s and on labour market reforms. Old age social security expenditure in Italy is high (14% of GDP) and the system has been very generous on early...

In general, retirement is seen as a pure labor supply phenomenon, but firms can have strong incentives to send expensive older workers into retirement. Based on the seniority wage model developed by Lazear (1979), we discuss steep seniority wage profiles as incentives for firms to dismiss older...

For the purpose of studying the consequences of the ageing of the Swedish population a group of scientists have enlarged the microsimulation model SESIM - originally developed at the Swedish Ministry of Finance - with modules that simulate health status, take up of sickness benefits, retirement,...

This paper studies optimal insurance against private idiosyncratic shocks in a life-cycle model with intensive labor supply and endogenous retirement. In this environment, the optimal labor tax is hump-shaped in age: insurance benefits of taxation push for increasing-in-age taxes while rising...

We use matched employer-employee data from Sweden to study the role of the firm in affecting the stochastic properties of wages. Our model accounts for endogenous participation and mobility decisions. We find that firm-specific permanent productivity shocks transmit to individual wages, but the...

Although elderly men and women share many of the same problems as they age, their lives are likely to follow different courses. Women are more likely than men to live into old old-age and are more likely to spend part of their young old-age caring for husbands or parents. By providing this...
