This paper critically evaluates the effects of population ageing on labour productivity with particular reference to New Zealand. A number of potential long run mechanisms are considered: complementarity of workers by age, age-specific productivity of individuals, new technology discoveries and...

This paper applies an overlapping generations model in order to evaluate the implications of intergenerational smoothing of New Zealand’s future fiscal costs. The analysis complements the New Zealand fiscal projections of Bell et al. (2010) and the New Zealand tax smoothing analysis in Davis...

The purpose of this paper is to extend the simulation analysis of population ageing in Guest, Bryant and Scobie (2003).
