Prices permeate contemporary life. From the cost of basic foodstuffs in developing countries to the pay of CEOs in rich ones, the question of the politics and ethics of pricing everything through the market dominates public life. At the same time, we know that dilemmas about how to value fairly, but also efficiently, goods and services have been with us for more than two thousand years, since the times of Aristotle in Ancient Greece. Through the course of the centuries, important thinkers like Thomas Aquinas, Adam Smith and Karl Marx all devoted considerable effort to try to understand how prices could reflect the intrinsic worth of the objects workers produce and exchange with other people. This is the question of the "just price." This volume represents the first systematic attempt to address this ancient debate through the use of qualitative empirical research, particularly ethnography.   The volume comprises a substantial introduction that sets out the terms of the debate, proposing four different approaches to the just price, plus eight case studies based on fieldwork carried out in four different continents (Africa, Asia, Europe and Latin America), ranging from topics such as fair trade, human rights and recycling, to organic agriculture, the rose oil industry, rural and urban marketplaces.   Bringing together the most recent scholarship in economic anthropology and associated fields to investigate the social, political and ethical consequences of market prices on ordinary people, this book is of interest to researchers in anthropology, sociology, history and geography.
