This book discusses a set of radical changes in economic institutions and policies designed to show an efficient but socially acceptable third way between Keynesian inflation and monetarist unemployment, and between the inefficiencies of socialist centralisation and the ravages of unrestrained capitalist competition. It consists of a reprint of Efficiency, Equality and the Ownership of Property together with four recent papers including a highly revised version of the well-known tract Agathotopia: The Economics of Partnership.
