We model how unemployment benefit sanctions - benefit reductions that are imposed if unemployed do not comply with job search guidelines - affect unemployment. In our analysis we find that not only micro-effects concerning the behaviour of individual unemployed workers are relevant, but also...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on funded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

This study investigates the determinants of applications for US disability benefits between 1986 and 1993 using a semiparametric discrete factor procedure. Approximating a dynamic optimization model, the estimation carefully accounts for a variety of potential biases that weren’t addressed in...

This study investigates the labour force behaviour of older married couples in Germany. Monthly observations from the first 11 waves of the German Socio-Economic Panel (GSOEP) are used to describe and analyse the relationship between the labour force behaviour of husbands and wives. The...

In a stochastic two-period OLG model, featuring an aggregate shock to the economy, ex-ante optimality requires intergenerational risk sharing. We compare the level of time-consistent intergenerational risk sharing chosen by a social planner and by office seeking politicians. In the political...

Why do voters support PAYG social security systems? Browning (1975) suggested that for a majority of voters, who consider past contributions as a sunk cost, unfunded systems may represent a better investment than alternative assets, such as mutual or pension funds. I quantify the relevance of...

Recent reforms of the Italian social security system (Amato-Dini reforms) aimed at reversing the upward trend in Government pension spending. The main provisions of these reforms are: i) the adoption of a (unfunded) defined contribution system as a basis for computing pensions benefits, ii) a...

We explore intergenerational and international risk sharing in a general equilibrium multiple-country model with two-tier pensions systems. The exact design of the funded tier is key for the way in which risks are shared over the various generations. The laissez-faire market solution fails to...

An opinion poll on a representative sample of Italian citizens suggests that it does. We focus on reforms that would lengthen retirement age and/or cut pension benefits. After controlling for individual features of the respondent, we find that individuals who are more informed about the costs...

This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall 'life-cycle' risk aversion. We provide a...
