TY - RPRT AU - Elias, Julio AU - Lacetera, Nicola AU - Macis, Mario TI - Efficiency-Morality Trade-Offs in Repugnant Transactions: A Choice Experiment PY - 2016/Sep/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 10187 UR - https://www.iza.org/publications/dp10187 AB - Societies prohibit many transactions considered morally repugnant, although potentially efficiency-enhancing. We conducted an online choice experiment to characterize preferences for the morality and efficiency of payments to kidney donors. Preferences were heterogeneous, ranging from deontological to strongly consequentialist; the median respondent would support payments by a public agency if they increased the annual kidney supply by six percentage points, and private transactions for a thirty percentage-point increase. Fairness concerns drive this difference. Our findings suggest that cost-benefit considerations affect the acceptance of morally controversial transactions, and imply that trial studies of the effects of payments would inform the public debate.
