Abstract:
Two sources of workers’ pro-social motivation have been considered in the literature: action-oriented altruism and output-oriented altruism. This paper presents evidence from a field experiment, which aims to identify and quantify them. The idea behind our experimental design is to measure in a precise way the level of effort exerted in an environment that elicits purely selfish behavior and compares it to effort in an environment that also induces action-oriented altruism. We then compare the latter to effort exerted in an environment where both types of altruistic preferences are elicited. We find that action-oriented altruism accounts for a significant increase in effort, while there is no additional impact due to output-oriented altruism. We also find significant gender-related differences in the treatment effect: women are very responsive to the treatment condition eliciting action-oriented altruism, while men’s behavior is not affected by any of the treatments.
