This Paper starts from the result of Rochet (1989), that with distortionary income taxes social insurance is a desirable redistributive device when risk and ability are negatively correlated. This finding is re-examined when ex post moral hazard and adverse selection are included, and under...

In this Paper, we discuss the main characteristics of European mandatory pension systems and the implications for these systems of increasing factor mobility. In particular, we expect the extent of redistribution (both intra- and intergenerational) in national pension systems to decrease. The...

The pool of early retirees is characterized by a large heterogeneity along several criteria. The present paper focuses on the key distinction between those in forced early retirement and those who retire early by individual choice. We start by estimating a retirement probit model for older...

We analyse the economic impact of a simultaneous aging shock in two countries. The countries are identical in all respects except the financing scheme of their public pension system. While one relies on capitalization, the other one relies on a pay-as-you-go scheme. We show that the two...

The present Paper studies the retirement incentives for elderly people in Belgium. We model the incentive structure built into the various public early retirement and retirement systems. First, we compute indicators of benefit entitlement such as the social security wealth. Then, we use three...

In this paper we use data on five social inclusion indicators (poverty, inequality, unemployment, education and health) to assess and compare the performance of 27 European welfare states (EU27) in 2008. Aggregate measures of performance are obtained using index number methods similar to those...

In many countries pension systems involve some form of earnings test; i.e., an individual’s benefits are reduced if he has labour income. This paper examines whether or not such earning tests emerge when pension system and income tax are optimally designed. We use a simple model with...

This paper studies the determination through majority voting of a pension scheme when society consists of far-sighted and myopic individuals. All individuals have the same basic preferences but myopics tend to adopt a short term view (instant gratification) when dealing with retirement saving....

This paper studies the design of retirement and disability policies. It illustrates the often observed exit from the labour force of healthy workers through disability insurance schemes. Two types of individuals, disabled and leisure-prone ones, have the same disutility for labour and cannot be...

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 leads to...
