We consider corruption behavior in a three-players game : Principal, Agent, Corrupter. When the Principal chooses a fair wage, the Agent faces con°icting interests to reciprocate. This delegation effect is expected to lower the level of corruption as compared to what arises in two-players settings. We set up two experiments varying in the exogeneity of the delegation relationship. The experimental evidence supports the delegation effect. This, in turn, could account for the deterrence effect of wage on corruption even in the absence of detection.
