Harberger expresses doubt the economics could achieve a consensus about the weight that should be attached to the welfare of different groups. however, currently existing methods used for valuing different health states, such as discrete choice experiments, could be used to elicit information from the public about their preferences for various equity-efficiency trade-offs. For example, Caiet al. use a stated-preference survey to explore equity trade-offs in choices over policies to prevent climate change. They find that some respondents willingness to pay is higher when they believe that the impacts of climate change may be borne disproportionately by the world's poor. Stated-preference surveys could similarly elicit willingness to pay for the reductions in health inequities due to social determinants of health interventions. It would then be a straightforward exercise to incorporate estimates of willingness to pay to reduce health inequities in cost-benefits analyses of social determinants of health interventions
