Monetary policy is superneutral in an overlapping generations model. Previous authors have argued that superneutrality does not hold in such a setting. However, the standard results rely on the counter-factual premise of helicopter money and are overturned if money creation through open market...

The paper evaluates the theoretical literature on public pension schemes. First, the terms pay-as-you-go and capital reserve are made precise. These two systems are then compared, followed by a consideration of their efficiency properties. Thereafter conversion policies are discussed.

Public pension schemes can be designed either as capital reserve systems or as unfunded (or pay-as-you-go) schemes. In the literature it has been alleged that unfunded schemes are intergenerationally efficient in Pareto's sense. Here we show that this holds only if contributions to the system...
