We examine the explanatory power of cascade models by implementing the BDM-mechanism in a simple cascade experiment in which subject have to decide on the prediction of a randomly choasen urn. Assigned price limits to participate in the prediction game are used as indicators of subjective...

We adopt an evolutionary approach to investigate whether and when condi-tional cooperation can explain the voluntary contribution phenomenon oftenobserved in public goods experiments and in real life. Formally, conditionalcooperation is captured by a regret parameter describing how much an...
