Social insurance for the elderly is judged responsible for the widely observed trend towards early retirement. In a world of laissez-faire or in a first-best setting, there would be no such trend. However, when first-best instruments are not available, because health and productivity are not...

The Swedish universal welfare model relies on a high tax level to finance a variety of transfers to the workingage population both in the form of income replacements and income supplements and as services for health-, child- and elderly care. The available evidence, reviewed in this <I>Working...</i>

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

This paper shows that the combination of habit formation – present consumption creating additional consumption needs in the future – and myopia may explain why some retirees are forced to "unretire", i.e., unexpectedly return to work. It also shows that when myopia about habit formation...

This paper studies the normative problem of redistribution among individuals who can influence their longevity through a non-monetary effort but have different taste for effort. As benchmarks, we first present the laissez-faire and the first best. In the first best, the level of effort is always...

This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to ‘unretire’, i.e., unexpectedly return to work. It also shows that when myopia about habit formation...

A model is presented for simulating the tax burden on highly skilled manpower. The effective average tax rate, defined as the relative wedge between total remuneration and disposable income, is computed. Income and payroll taxes and social security contributions not yielding an equivalent...

This paper studies the optimal linear tax-transfer policy in an economy where agents differ in productivity and in genetic background, and where longevity depends on health spending and genes. It is shown that, if agents internalize imperfectly the impact of genes and health spending on...
