15 November 2017Prosocial behaviors contribute to the wellbeing of others following activities like charitable giving or volunteering. Theories that explain prosocial behaviors are pure altruism and impure altruism, inequality aversion reciprocity and conditional cooperation. These theories are linked to a system of motivations, that is intrinsic motivation, extrinsic motivation, and image motivation. Social norms play a key part in one’ s motivations to behave prosocially, in particular with regard to image motivation and likely sanctions when one’s deviates from these norms. The expressive power of law leads to norms legitimacy. Prosocial behaviors are mainly studied in the literature in economics and psychology, especially in behavioral and experimental economics.
