In this work we use data on response times from a public good experiment to test the hypothesis that cooperation is instinctive, under the assumption that the longer the time of the decision, the less instinctive the choice. Results seem to support the hypothesis that cooperation is instinctive, while defection is 'rational'. Moreover, as the experiment is designed also to assess the effects of the consumption of relational goods on cooperation, we are also able to state that some types of relational goods, like team working, produce additional cooperation, but make it less spontaneous. We also detect that males seem to behave more instinctively than females.

The rising star of scholarly publishing is Open Access (OA). Even some traditional journals now offer this option on author payment, and many full freely accessible journals are now available to scholars, providing relief to research institutions increasingly unable to afford the escalating subscription rates of serials. However, proper recognition of full OA journals by the community remains a major obstacle to overcome if they are to become a viable alternative for scholarly communication. Through a survey, this work investigates economics scholars' attitudes to OA, and attempts to outline the state of practices and norms governing individuals' publication choices. (JEL L17, L86, O33)
