The specificities of the workforce with a migrant background are often neglected in studies of retirement. Similarly, many studies of migration’s impact on pensions often focus on aggregate outcomes – system sustainability or distributive characteristics. The present paper provides a fresh...

Recent estimates of the marginal cost of public funds differ substantially. Some studies argue that the efficiency cost of taxation counter the welfare gain connected to redistribution of income. Hence, the efficiency cost of taxation should not be included as a cost of public goods provision....

We study optimal nonlinear income taxation when earnings can differ because of both ability and luck, so the income tax has both a redistributive role and an insurance role. A substantial literature on optimal redistribution in the absence of uncertainty has evolved since Mirrlees' original...

This paper analyzes the welfare effects of the Italian social security system in an economy with uncertainty on wages, financial market returns and life expectancy. The introduction of a pension system reproducing the Italian statutory scheme turns out to decrease ex-ante individual welfare,...

This paper considers the quantitative role of growth in the size of the social security program in contributing to the collapse of personal saving in the U.S. over the last few decades. Using a calibrated, general equilibrium life-cycle model this paper shows that social security may not be to...

In this fascinating new field, this paper offers some reflections on portability of social benefits, and tries to identify promising research topics. These reflections are organized in three sections. The first analyzes the channels that underpin the positive value of portability of social...

We extend 'economic equivalence' results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are 'politico-economically...

This paper studies the welfare and policy implications of globalization when risk averse workers face the risk of unemployment. If the jobs performed by domestic workers can be easily substituted by imports, then globalization reduces wages and increases unemployment. In this situation, in the...

The present paper quantifies the importance of family insurance for the analysis of social security. We therefore augment the standard overlapping generations model with idiosyncratic labor productivity and longevity risk in that we account for gender and marital status. We simulate the...

Building on the existing literature that examines the extent of redistribution in the Social Security system as a whole, this paper focuses more specifically on how Social Security affects the poor. This question is important because a Social Security program that reduces overall inequality by...
