Robust Mechanism Design and Social Preferences
CESifo, Munich, 2014
CESifo Working Paper No. 4713
We study a classic mechanism design problem: How to organize trade between two privately informed parties. We characterize an optimal mechanism under selfish preferences and present experimental evidence that, under such a mechanism, a non-negligible fraction of individuals deviates from the intended behavior. We show that this can be explained by models of social preferences and introduce the notion of a social-preference-robust mechanism. We characterize an optimal mechanism in this class and present experimental evidence that it successfully controls behavior. We finally show that this mechanism is more profitable only if deviations from selfish behavior are sufficiently frequent.
