Warm-Glow Giving and Freedom to be Selfish

Warm-glow refers to other-serving behavior that is valuable for the actor per se, apart from its social implications. We provide axiomatic foundations for warm-glow by viewing it as a form of preference for larger choice sets, in the sense of the literature on freedom of choice. Specically, an individual who experiences warm-glow prefers the freedom to be sel…sh: she values the availability of sel…sh options even if she plans to act unsel…shly. Our theory also provides foundations for empirically distinguishing between warm-glow and other motivations for prosocial behavior. The implied choice behavior subsumes Riker and Ordeshook (1968) and Andreoni (1990).
