The starting point of Paul Streeten's book is the dilemma, faced by policy makers in many developing countries: should the price of food be high, in order to stimulate production, or low, in order to prevent poor food buyers from starving? The author goes on to discuss the role of prices in the light of these and other objectives. 'It is the work of one of our wisest scholars on what I consider to be the key policy issue for economic development in the 1980s...this provocative essay will be required reading for anyone working on agricultural price policy.' C.Peter Timmer 'It provides solid and practical guidance to scholars and decision-makers. It is lucid, balanced and, above all, useful.' Robert Klitgaard 'Paul Streeten is well known for his gift of explaining the pros and cons of difficult policy issues in a clear, simple and realistic way, appealing to policy-makers, students and the wider development community, as well as to academic colleagues. This gift is fully displayed in his new book, and readers are bound to emerge with a better awareness of the conflicts and policy reforms which are involved.' H.W.Singer

This is Volume XXI of twenty-two in a series on Social Theory and Methodology. First published in 1958, this is a selection of essays on practical methodology when trying to answer the question of what are the new presuppositions of social thought which can do justice to the changes in social organisation. Mydral attempts to illustrate his repeated attempts to explore the logical, political and moral foundations of social thought and action, as he pursued diverse academic and political activities.
