In this paper we experimentally investigate whether partial coercion can in combination with conditional cooperation increase contributions to a public good. We are especially interested in the behavior of the non-coerced populations. The main ļ¬nding is that in our setting conditional cooperation is not a strong enough force to increase contribution levels. Although, non-coerced subjects rationally adjust their beliefs about contribution behavior of coerced subjects they do not increase their own contributions to the public good accordingly. This points to the limits of the actual strength of conditional cooperation and puts some doubt on the idea that it is crucial in overcoming social dilemma problems.
