To do this well, policymakers must understand underlying preferences and rank policies according to these preferences. In this paper, we use multi-criteria decision analysis techniques to understand the relative attractiveness of retirement policy reforms in New Zealand. Using a nationally representative sample, we estimate individual preferences over seven aspects of retirement policy, characterise the diversity of these preferences, and rank three different policy options. We find that a policy which raises taxes to prefund the government retirement income scheme would be supported by a majority of people of all ages and income groups, and would be much more popular than a policy that raises the age of eligibility. The results suggest multi-criteria decision analysis has considerable potential to help policymakers develop policies that are aligned with people’s preferences.en-AUAuthor/s retain copyrighthttps://creativecommons.org/licenses/by-nc-nd/4.0/2019-0910.22459/AG.26.01.2019.02Creative Commons licence (CC BY-NC-ND; creativecommons.org/licenses/by-nc-nd/4.0/)
