Motives to give in economics and psychology: A step toward unification.

Parallel literatures in economics and psychology investigate why people voluntarily help others in need. Economics has investigated an other-regarding motive (altruism) and a self-regarding motive (warm-glow) and has used choice-based observations for inference. Psychology has similarly examined other- and self-regarding motives and has developed survey-based measurements to assess corresponding measures of empathic concern and a moral principle of care. This paper explores whether and how elicitation of charitable motives from economics relate to measurements from psychology. We find that when making donations to others in need, individuals with stronger empathic concern dispositions are more altruistic/other-regarding. Also, those who more strongly endorse a moral principle of care are more motivated by warm-glow/self-regard. The results connect two literatures, offer novel evidence from economics about theories developed in psychology, and demonstrate that well-developed survey questions from psychology can be predictive of the choice-based inference on altruistic and warm-glow motivations from economics.
