Many economists and psychologists refuse the idea that behaviour could be based on any other motives than selfish and hedonistic ones, at least in the context of economy, mainly based on a methodological premise, not so often on empirical research. The corresponding image of man that is inherent...

Recent research has cast some doubt on the general validity of outcome-basedmodels of social preferences. We develop a model based on cognitive dissonance thatfocuses on the importance of self-image. An experiment (a dictator game variant)tests the model.First, we nd that subjects whose choices...
