Policy interventions that affect or are mediated through the family typically assume a behavioural response. Policy analyses proceeding from different disciplinary bases may come to quite different conclusions about the effects of policies on families, depending how individuals within families...

The paper uses a simulation model to assess the effects of population ageing on government health expenditures in New Zealand. Population ageing is defined to include disability trends and “distance to death”; government health expenditures are defined to include both acute and long-term...

The purpose of this paper is to extend the simulation analysis of population ageing in Guest, Bryant and Scobie (2003). In that paper a single-good Ramsey-Solow model was calibrated for New Zealand and used to simulate the impact of population ageing on optimal national saving and average living...

Many policy models require assumptions about future population trends. Sensitivity tests for these assumptions are normally carried out by comparing population projection variants. This paper outlines some of the conditions that variant-based sensitivity tests must meet if they are to be...

Over the next 50 years, New Zealand’s population will age substantially. There has been wide debate about whether New Zealand should prepare for population ageing by increasing national savings. The debate had not, however, involved explicit consideration of possible time paths for savings,...

This paper reviews and extends a new framework, developed by Razin, Sadka, and Swagel, for capturing the effect of population ageing on public support for government social expenditures. Razin et al construct up an overlapping generations, median voter model, and investigate the empirical...

New Zealand has, by OECD standards, high birth rates. This has provided New Zealand with a relatively young population and continuing labour force growth. Both these features are, on many accounts, good for economic growth. Yet most discussions of New Zealand’s economic performance and its...

The paper reviews data on long-term changes in the age structure of the New Zealand population. It sets out trends and projections for the age structure of the national population, and for associated measures of dependency. It describes the influences on age structure of fertility, mortality,...

This paper examines the hypothesis that a greater stock of migrants in New Zealand from a particular country leads to more trade between that country and New Zealand. The literature suggests that migrants can stimulate trade by lowering transaction costs, and by bringing with them preferences...

Many New Zealand-born people migrate overseas, creating a diaspora, and many overseas-born people migrate to New Zealand. Both the diaspora and the overseas-born population in New Zealand may facilitate the international exchange of goods and ideas. Much discussion of international linkages has,...
