This paper assesses Italy’s 2019 tax and benefit reforms, analyses hypothetical reforms and proposes a reform package that balances goals of reducing poverty, encouraging employment and fiscal sustainability. Using the OECD’s Tax-Benefit and the EUROMOD microsimulation models, it shows that...

This Handbook entry presents a conceptual, normative overview of the subject of taxation. It emphasizes the relationships among the main functions of taxation—notably, raising revenue, redistributing income, and correcting externalities—and the mapping between these functions and various...

We study interactions between progressive labor taxation and social security reform. Increasing longevity puts fiscal strain that necessitates the social security reform. The current social security is redistributive, thus providing (at least partial) insurance against idiosyncratic income...

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...

Using an OLG model with skill uncertainty and private savings, we investigate whether an optimally designed set of public pension transfers can usefully supplement a nonlinear labor income tax as a welfare-enhancing policy instrument. We consider a Mirrleesian setting where agents' skills are...

We characterize an optimal redistributive pension scheme when individuals face temptation, but can exert costly self-control (as in Gul & Pesendorfer, 2001; 2004). Our results challenge the common wisdom that forced savings tend to reduce individuals' mental cost of self-control. In our model,...
