    Abstract: It is often argued that the tax on continued work should be removed by implementing actuarially fair schemes. However, these schemes cannot help fund the expected Social Security deficit. This paper proposes to give individuals only a fraction of the marginal actuarially fair incentives in case of postponed retirement. Social Security then faces a tradeoff between giving enough incentives to make individuals actually delay retirement and giving little increase in pensions in order to help finance its expected deficit. This trade-off is captured by a Laffer curve that we quantify on French data. Furthermore, we analyze the interactions between wealth and retirement behavior.
    Keywords: retirement behavior and wealth, actuarially fair benefits

    Abstract: This paper models the relationship between growth, technology-lifetime, entry, and competition in a vintage-knowledge model of endogenous growth and perfect competition. The model has a unique steady state REE equilibrium. Variations of R&D-efficiency lead to a negative relation between growth and vintage-lifetime and indicate a non-monotonic relation between growth and competition. A shift of population size and its growth rates have qualitatively different consequences here than in standard models. The extent of entry constitutes a buffer, neutralizing the effect of population size or population growth rates on per-capita income levels and growth rates.
