The provision of public goods provides a fruitful topic for an interdisciplinary study since it has drawn the attention of many economists as well as psychologists. It allows for a comparison of basic conceptual issues involved in the construction of theories in the two domains. This study will focus in particular on the different roles ascribed by various theories to distinct decision rules and expectations when explaining individuals’ decisions to contribute to public goods. Experimental evidence will be used to assess the relative strength of different ideas. It will also be investigated whether successful ideas in one field can be translated to the other.
