We study the role of loss aversion in behaviors with significant prosocial motives. We conduct a field experiment in a large developing country that uses gain-loss framing to deliver information about how vaccination reduces the spread of COVID-19, and confirm vaccine take-up using self reports and government certificates. For both vaccination intentions and vaccine take-up, we find positive impact of information treatment, with significantly greater impact for the messages focusing on the “loss” in prosocial motives when not vaccinated. We explain our findings in a theoretical model and calibrate the prosocial loss aversion parameter to be within range of private loss aversion parameter estimates in the literature.
