Replications and crowd science in economic research

Levent Neyse, Chercheur en économie comportementale, German Institute for Economic Research

Résumé : This talk will discuss how economics and the social sciences have been reshaped in response to the replication crisis through open science practices and emerging standards for research transparency. Particular attention will be given to crowdscience, replication studies, and preregistration in economic research. The talk will also introduce Lab², a Berlin-based metascience lab, and provide an overview of some of its ongoing studies.

Volunteer or Donate? How People Give under Context-Dependent Norms

Résumé : Why do people sometimes give time and at other times give money? We study how this choice is linked to context-specific norms. In an experiment comparing climate and history domains, we document that volunteering is seen as more appropriate in the climate context, while no clear norm favors either form of giving in the history context. This difference is mirrored in behavior: social norms are associated with volunteering when there is a social norm for volunteering, whereas personal norms are more closely associated with behavior when shared expectations are weak. Comparing stakeholders and spectators, we find no evidence that norm perceptions reflect motivated reasoning. Together, the results indicate that social norms are associated with behavior when a shared norm is present, whereas personal norms are more relevant when it is not
