Clarence Edwin Ayres was the leading American institutionalist economist in the post-World War II era. His innovative theories concerning the causes and significance of technological change provided the philosophical framework for that school of economics called institutionalism. In his recognition that the critical economic issues of the future would be the realization of the full economic potential of industrial society and the development of the third world, he was at least twenty years ahead of his time. In addition, Ayres's influence as an economics teacher at the University of Texas at Austin went well beyond the discipline of economics to students of anthropology, psychology, philosophy, education, and even music and art. This book constitutes the first major appraisal of the work and influence of C. E. Ayres. The essays are written from a transatlantic as well as a national viewpoint and do not evince anyone ideological bias. As John Kenneth Galbraith says in his Foreword, the essays are not meant as a monument to Ayres; instead, they critique what he thought and did, showing his range of interests, his diligence, his originality of mind and method.
