Is neuroeconomics a flimsy fad likely to pass without leaving a discernible trace in economics? Or is it a promising new field with the potential to enrich and improve economic theory? Neuroeconomics brings together a unique mix of perspectives ranging from philosophy of science to neuroeconomics practice to reflect on the promises and limitations of neuroeconomics for the future of economics. The analyses collected in the volume suggest that although neuroeconomics raises methodological worries that ought to be dealt with, it might contribute to economics in various ways, some perhaps more promising than others. One thing comes out clearly, though: a complete insulation of economics from neuroscience and psychology is likely to do economics more harm than good.This book was originally published as a special issue of Journal of Economic Methodology.
