In this paper we identify a number of objectionable features of the German retirement benefit formula. We show that groups of insureds with higher than average life expectancy, in particular high-income groups, are subsidized by the rest of the membership because the formula neglects differences...

This paper studies optimal insurance against private idiosyncratic shocks in a life-cycle model with intensive labor supply and endogenous retirement. In this environment, the optimal labor tax is hump-shaped in age: insurance benefits of taxation push for increasing-in-age taxes while rising...

This paper assesses how a permanent shift from financing a public pay-as-you-go pension by direct (labour income) taxation towards financing it by indirect(consumption) taxation affects the economy and welfare. To this end, we use anoverlapping-generations-augmented two-region general...

Conventional wisdom states that the statutory split of payroll taxation between firms and workers is of no macroeconomic relevance, because the tax incidence is fully determined by the market structure. This paper breaks with this view by establishing a theoretical link between the statutory...

We model a pay-as-you-go (PAYG) pension system as a series of incomplete intergenerational contracts. Each generation pays a pension to its parents as the price for a premortal transferral of economic property rights. The terms of this intergenerational trade are fixed in a social contract,...

I study the impacts of financing rules for financial surpluses in pay-as-you-go pension systems on the business cycle and the life cycle in a dynamic stochastic large-scale overlapping generations model, where households take the inter-temporal links between contributions and pension benefits...

We study whether a better knowledge of the functioning of pay-as-you-go pension systems and recent demographic trends in the hosting country affects natives' attitudes towards immigration. In two online experiments in Italy and Spain, we randomly treated participants with a video explaining how,...

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...

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,...
