We investigate which form of corporate culture is most effective in enhancing individual performance in creative tasks conducted in group settings. We combine a series of experiments with a questionnaire on corporate values to test whether performance ranking and incentives succeed in instantiating a creative corporate culture. Being ranked against competitors and setting incentives at the group level serves as a social cue that appears to induce in members a significantly stronger pro-social attitude. When this attitude is shared by group members, a social norm of high effort emerges, and creative performance is significantly higher.
