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 driven by one's desire for freedom to act selfishly. Specifically, an individual who experiences warm-glow values the availability of selfish options even if she plans to act unselfishly. Our theory accommodates the empirical findings on motivation crowding out and provides clear-cut predictions for empirically distinguishing between warm-glow and other motivations for prosocial behavior, a task of obvious importance for policy. The choice behavior implied by our theory subsumes Riker and Ordeshook (1968) on voting and Andreoni (1989, 1990) on the provision of public goods.
