Estimating weights for the active ageing index (AAI) from stated preferences: Proposal for a discrete choice experiment (DCE)
Book chapter, 2018
This chapter outlines how Discrete Choice Experiments (DCEs) could be used to estimate alternative weights for the Active Ageing Index (AAI) based on stated preferences. The approach is based on Random Utility Theory and could provide valuable information on marginal substitution rates between AAI indicators and domains. Complementing the current AAI methodology with preference-based weights may also allow assessing preference variation across different social, cultural or geographic contexts. This would help define more targeted active and healthy ageing policies and interventions, incorporate stakeholders’ views in the valuation of policy outcomes and enhance the acceptance of the Index as a tool for policy analysis.
