This paper analyzes the dynamic politico-economic equilibrium of a model where repeated voting on social security and the evolution of household characteristics in general equilibrium are mutually affected over time. In particular, we incorporate within-cohort heterogeneity in a two-period...

This paper studies the optimal design of a pension system together with publicly-provided individualized financial education. Agents can invest in both a risky and a non risky asset and can either under- or over-estimate the expected return of the risky asset. We show that, under perfect...

For more than 25 years, the Social Security Trust Fund has been projected to run out of money in 2033 (give or take a few years), potentially causing benefits to be severely reduced in the absence of corrective legislative action. Today (February 2024), projections are made by the Social...

This paper studies a problem of non linear taxation when individuals have different longevities resulting from a non-monetary effort (like exercising). We first present the laissez-faire and the first best. Like Becker and Philipson (1998), we find that the laissez-faire level of effort is too...

The paper examines the possible effects of introducing a large-scale welfare reform in Sweden, namely, the introduction of comprehensive welfare accounts. Under this policy, individuals make mandatory contributions to accounts, which they can top up with voluntary contributions. In return,...

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 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...

Advances in information technology have improved the administrative feasibility of redistribution based on lifetime earnings recorded at the time of retirement. We study optimal lifetime income taxation and social insurance in an economy in which redistributive taxation and social insurance...

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...
