Evolutionary economics sees the economy as always in motion with change being driven largely by continuing innovation. This approach to economics, heavily influenced by the work of Joseph Schumpeter, saw a revival as an alternative way of thinking about economic advancement as a result of Richard Nelson and Sidney Winter's seminal book, An Evolutionary Theory of Economic Change, first published in 1982. In this long-awaited follow-up, Nelson is joined by leading figures in the field of evolutionary economics, reviewing in detail how this perspective has been manifest in various areas of economic inquiry where evolutionary economists have been active. Providing the perfect overview for interested economists and social scientists, readers will learn how in each of the diverse fields featured, evolutionary economics has enabled an improved understanding of how and why economic progress occurs.

This book contains the most sustained and serious attack on mainstream, neoclassical economics in more than forty years. Nelson and Winter focus their critique on the basic question of how firms and industries change overtime. They marshal significant objections to the fundamental neoclassical assumptions of profit maximization and market equilibrium, which they find ineffective in the analysis of technological innovation and the dynamics of competition among firms. To replace these assumptions, they borrow from biology the concept of natural selection to construct a precise and detailed evolutionary theory of business behavior. They grant that films are motivated by profit and engage in search for ways of improving profits, but they do not consider them to be profit maximizing. Likewise, they emphasize the tendency for the more profitable firms to drive the less profitable ones out of business, but they do not focus their analysis on hypothetical states of industry equilibrium. The results of their new paradigm and analytical framework are impressive. Not only have they been able to develop more coherent and powerful models of competitive firm dynamics under conditions of growth and technological change, but their approach is compatible with findings in psychology and other social sciences. Finally, their work has important implications for welfare economics and for government policy toward industry.

The contributors to this volume focus on the political and value issues that, in their shared view, underlie the global environmental crisis facing us today. They argue that only by transforming our dominant values, social institutions and way of living can we avoid ecological disaster.

not gentle to the capitalists" (Schumpeter, 1991). Thus, by instead portraying the conflict between entreprenuerial activity and the sociology of the modern state, he came quite close to the analysis carried out by Thorstein Veblen some decades earlier, who emphasized the conflict between p- gressive technology and the institutions of a contemporary "predatory dynastic State of early modern times, superficially altered by a suffusion of democratic and parliamentary institutions" (Veblen, 1964, p. 398). Modern neo-Schumpeterian approaches have continued to build on this groundwork provided by their master. During recent years there has been a great upsurge of discussion on technology, innovations, technological regimes, etc. from the dynamic perspective provided by Schumpeter (Dosi, 1984, Rosegger, 1985; Dosi et al., 1988). Thus the search process for (t- poral) extra profits has been stressed and has been used for modelling attempts. The wider institutional framework for technological change and innovation activity has also been strongly developed more recently. Hence emphasis has grown in the study of technological and industrial regimes, path dependency, and the network approach, developed recently, that social relationships structure the opportunities and constraints that face firms and agents that, for example, carry out innovations (Snehota, 1990).

The central theme of this book is competition treated as an evolutionary process in which the focus is upon economic change and not economic equilibrium. This theme is explored by linking together differences in economic behaviour with the role of markets as co-ordinating institutions. In this picture innovation plays a central role as a primary source of differential behaviour of firms and the purpose of the book is to identify the consequences of these differences for competition and competitive advantage.

How evolutionary ideas can be used to reconstruct economics.

This exciting new book from Geoffrey Hodgson is eagerly awaited by social scientists from many different backgrounds. This book charts the rise, fall and renewal of institutional economics in the critical, analytical and readable style that Hodgson's fans have come to know and love, and that a new generation of readers will surely come to appreciate.
