'...all papers in both parts of this volume are of high quality and extend the frontiers of both behavioural and experimental economics. The applications span across the gamut of fields in economics and the editors of this volume should be commended for collating and integrating these nuggets into a volume that makes for stimulating reading and an excellent introduction to the field.' - Shreekant Gupta, Indian Economic Review 'Overall, this volume is noteworthy for the breadth of topics covered and psychological constructs incorporated into economic models. Several of the studies contribute to the growing literature in experimental economics.' - Roxane Gudeman, Feminist Economics
