We develop a simple model of fiscal competition among ageing municipalities. When ageing advances, gerontocracies and social planners gradually substitute publicly provided goods aimed at the mobile young population for publicly provided goods for the elderly. This substitution process does not...

We study the sustainability of pension systems using a life-cycle model with distortionary taxation that sets an upper limit to the real value of tax revenues. This limit implies an endogenous threshold dependency ratio, i.e. a point in the cross-section distribution of the population beyond...

This paper analyzes the impact of aging on capital accumulation and welfare in a country with a sizable unfunded social security system. Using a two-period overlapping generation model with potentially endogenous retirement decisions, the paper shows that the type of aging, i.e. declining...

This research empirically establishes and theoretically motivates the hypothesis that population aging has a hump-shaped effect on inventive activity. We estimate this hump-shaped relationship in a panel of 33 OECD countries over the period 1960-2012. The increasing part of the hump captures the...

To assess the likely effects of population ageing on the outcomes of direct democracy, we analyze the effect of age on voting decisions in public referenda. To this end, we provide the first quantitative review of the literature and a case study of the Stuttgart 21 referendum on one of the...

İmrohoroğlu, İmrohoroğlu and Joines [1995, A life-cycle analysis of Social Security, Economic Theory, vol. 6, 83-114] show that the optimal replacement ratio of the pay-as-you-go public pension system in the US economy amounts to 30%. We extend their analysis to a model that 1) replicates...

Between 1950 and 2017, world average life expectancy increased from below-50 to above-70, while the fertility rate dropped from 5 to about 2.5. We develop and calibrate an analytic climate-economy model with overlapping generations to study the effect of such demographic change on capital...

The gains in life expectancy are expected to double the dependency ratio and increase population by 10% in Switzerland until 2050. To quantify the effects on pensions, taxes and social contributions, we use an overlapping generations model with five margins of labor supply: labor market...

We study transitions from EET tax regime to TEE regime in a defined-benefit pension scheme with a numerical overlapping generations model, using stochastic mortality projections as inputs. In a traditional pension scheme with no automatic longevity rules, such as a link between life expectancy...
