In light of the recent and ongoing surge of interest in Alfred Marshall's work, this new and original reference volume fills a gap in the literature through a detailed examination of his thought and of his contributions to economics and social science. The Companion places Alfred Marshall's ideas in their historical context, highlighting the many streams of social research originating from them. The contributors form a remarkable cast of leading experts, covering a spectrum of Marshallian themes and issues, including: - his life and work - background and influences - scope and methodology of economics - economic analysis - including distribution theory, industrial economics and money - social and political issues - relations with his contemporaries - the Marshallian tradition - relevance to contemporary economics. This comprehensive and multidisciplinary Companion illustrates the relevance of Marshall to present-day economic reality and as such will prove an invaluable reference tool for general economists and a wide ranging audience: historians of economic thought; economic, political and cultural historians; industrial, regional and development economists; economists interested in institutional, cognitive and evolutionary economics.
