  49. 49. Erasmus Centre forNeuroeconomicsConclusion (1/2)• Neuroeconomics and evolutionary economicsare published across natural and socialsciences• BUT there is a strong difference in terms ofwho is a practitioner.• It must be related to the nature of theinterdisciplinary relationship: analogous vsempirical
  50. 50. Erasmus Centre forNeuroeconomicsConclusion (2/2)• Neuroeconomics, as reflected by the survey, displaysa broader coverage of fields than one would suspect.=> definitions matter• Neuroeconomics seem to be relatively stablethrough time, tbc.• Strong differences in geographical coverage.=> Europe: one centre in economics! [caveat]
