'The authors of this volume are spot on when they note that "the perspective alters drastically when it is realized that economic exchange as it occurs in the real world is a laborious and costly process with uncertain and imperfect outcomes". We all have a lot to learn from this highly original, thought provoking contribution to our understanding of the very core of economic and development thinking.' - Finn Tarp, United Nations University - World Institute for Development Economics Research, Finland and University of Copenhagen, Denmark.
