We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

Superneutrality is demonstrated to no longer hold in the Sidrauski model as soon as agents are heterogenous with regard to their productivity. However, quantitative effects of inflation on the capital stock are found to be rather small.

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...
