The evolutionary approach to economics can be traced back as far as the eighteenth and nineteenth centuries in the work of Darwin, Smith and Malthus. These ideas have gradually developed since that time through Marx, Veblen and Marshall, and have recently experienced considerable attention. This book considers the development of evolutionary economics and its place in economic thought today. The book begins with a concise history of evolutionary economics which develops to examine the variety of approaches within the subject. The discussion continues with a rigorous analysis of why, in contrast to popular belief, evolutionary economics is not alien to neoclassical economics, arguing that it may even be considered to complement neoclassical economics. Continuing along this theme the firm is discussed from an evolutionary and neoclassical standpoint. Leading on from this is a discussion of modern model building in evolutionary economics and its relationship with Schumpeter's developmental work. Model building is examined further in relation to endogenous technological change and economic growth, and the effect that technological change and innovation can have on the spatial distribution of new industry. This book will be of special interest to evolutionary and post Keynesian economists and those interested in technological change and innovation.
