This book, the first of two volumes, brings together the work of Domenico Mario Nuti to highlight his significant and varied contribution to economics. Bringing together works from across Nuti's career, his distinctive intellectual framework is exemplified in relation to discussions on the drivers of economic growth and development, the most efficient economic system, the organisation of firms, and how economies should be managed. This volume gives particular attention to socialist economic systems, and the transition of former socialist countries to market economies. This book, through the inclusion of an introduction, aims to contextualise his ideas and illustrate their continued relevance. It will be of wide interest to students and researchers.
