We design an experiment to test whether incomplete crowding out in dictator games can be rationalized by the impurely altruistic preferences. By giving the recipients an endowment of varying levels, we create an environment in which crowding out may occur. We find that the behavior of 66% of the dictators can be rationalized by the impurely altruistic utility function.
