Schumpeter and the revival of evolutionary economics: an appraisal of the literature

During the last two decades we have seen a revival of interest in the works of Joseph Schumpeter and “evolutionary” ideas in economics more generally. A professional society honouring Schumpeter's name has been founded, and linked to it we have had for more than fifteen years now a professional journal devoted to this stream of thought. However, it has been argued that, despite these developments, the link between Schumpeter's own work and the more recent contributions to evolutionary economics is in fact rather weak. This paper considers this claim. Based on an analysis of Schumpeter's contribution to economics the paper presents an overview and assessment of the more recent literature in this area. It is argued that although there are important differences between Schumpeter's work and some of the more recent contributions, there nevertheless remains a strong common core that clearly distinguishes the evolutionary stream from other approaches (such as, for instance, so-called “new growth theory”). RID="*" ID="*" Many people have contributed to this paper in various ways. Jon Hekland at the Norwegian Research Council started it all by asking me to make an overview of the contribution from “evolutionary economics” to our understanding of contemporary economies. Several people helped me on the way by supplying written material, comments and suggestions, and I am indebted to all of them. Brian Arthur, Stan Metcalfe, Keith Pavitt, Erik Reinert, Paolo Saviotti and Bart Verspagen may be particularly mentioned. A preliminary version was presented at the conference “Industrial R&D and Innovation Policy Learning – Evolutionary Perspectives and New Methods for Impact Assessment” organised by the Norwegian Research Council (“SAKI”) at Leangkollen, Asker, April 18–19.2002. I wish to thank the discussant, Tor Jakob Klette, and the participants at the conference for useful feedback. Moreover I have benefited from comments and suggestions from the editors and referees of this journal. The final responsibility is mine, however.

Where Schumpeter was nearly right – the Swedish model and Capitalism, Socialism and Democracy<--RID="*"-->

In Capitalism, Socialism and Democracy Joseph A. Schumpeter concluded that socialism would eventually displace capitalism in Western democracies. This would come about as a result of the superior performance of capitalism. We extract six “stylized” propositions that are essential elements of Schumpeter's prediction about the fate of capitalism. These propositions are confronted with the development of the Swedish economy. The three main results of the analysis are: (1) The evolution of the Swedish economy closely followed Schumpeter's predictions until about 1980: Large firms became increasingly predominant in production and innovative activity, ownership of firms became more and more concentrated, individual entrepreneurship waned in importance, the general public grew increasingly hostile towards capitalism, and by the late 1970s explicit proposals for a gradual transfer of ownership of firms from private hands were launched. (2) Design of tax and industrial policies fueled a development of the economy along the lines predicted by Schumpeter. In general, the policies discouraged private wealth accumulation. In particular, the policies favored concentration of firms and concentration of private ownership. (3) The turning point away from the path to socialism coincides with real world developments that disclosed two major flaws in Schumpeter's analysis. First, the ever more obvious failure of socialism in Eastern Europe went against Schumpeter's assertion that socialism can work. Second, Schumpeter, who thought that modern technology would make the giant corporation increasingly predominant, did not foresee the revival of entrepreneurship that took place in the Western countries around 1980.     

A spectre is haunting the world – the spectre of global capitalism

Individual property rights are fruitful for economic development because they civilise self-interest by forcing it to serve the common good. The history of previous property rights “cycles,” however, shows that their ability to do this deterioriates over time because the laws of property fall under the control of those whom property is meant to discipline. Irresponsible ownership then intensifies inequality until a breaking point is reached. The present cycle is no exception, but its breaking point has been postponed by the growth of the democratically-inspired welfare state. Globalisation is now eroding the financial basis of this, because mobile capital can escape taxation, leaving labour to carry the burden. The main thrust of this movement is now found in the World Trade Organisation, whose control of intellectual property and commitment to free trade in money as well as goods, can only increase inequality between countries as well as within them. It represents individual property rights which are out of any form of social control, since there is no global mechanism for civilising self-interest. Schumpeter's sense of the impending demise of capitalism, if not of its replacement by socialism, may yet be vindicated.     

On bubbling dynamics generated by a stochastic model of herd behavior

This paper suggests a class of stochastic collective learning processes exhibiting very irregular behavior. In particular, there are multimodal long run distributions. Some of these modes may vanish as the population size increases. This may be thought of as “bubbles” persistent for a finite range of population sizes but disappearing in the limit. The limit distribution proves to be a discontinuous function of parameters determining the learning process. This gives rise to another type of “bubbles”: limit outcomes corresponding to small perturbations of parameters are different. Since an agent's decision rule involves imitation of the majority choice in a random sample of other members of the population, the resulting collective dynamics exhibit “herding” or “epidemic” features.

Routines and incentives in group tasks*

The artificial context “Target the Two” has been used in experiments to explore some of the features of routinization and learning. Two agents must learn to coordinate their actions to achieve a common goal, without being allowed to use verbal communication. This article reports an experiment, in which we compare the degree of routinization and the performance of players in two treatments. Each treatment submits players to the same sequence of starting configurations, but differs in terms of the payoff function. In the first treatment (A), the payoff is based on the number of moves required to achieve the goal, whereas in the second treatment (B) the payoff depends on the time required for completion. We observe that (1) in treatment B subjects tend to play in a more “routinized” way and (2) treatment B reduces the time spent on play, but does not decrease the resources (the number of moves) used, relative to treatment A.     

Religion and economic growth: was Weber right?

Evidence of falling wages in Catholic cities and rising wages in Protestant cities between 1500 and 1750, during the spread of literacy in the vernacular, is inconsistent with most theoretical models of economic growth. In The Protestant Ethic, Weber suggested an alternative explanation based on culture. Here, a theoretical model confirms that a small change in the subjective cost of cooperating with strangers can generate a profound transformation in trading networks. In explaining urban growth in early-modern Europe, specifications compatible with human-capital versions of the neoclassical model and endogenous-growth theory are rejected in favor of a “small-world” formulation based on the Weber thesis.     

Capitalism and democracy in the 21st century: a Kaleckian interpretation of a Schumpeterian problem

The paper reinterprets Schumpeter's views on the dynamic effects of taxation, as originally expressed in Crisis of the Tax State, from a Kaleckian perspective. In light of Schumpeter's rejection of Keynesian and Marshallian approaches to taxation, the paper argues that a recently developed Kaleckian approach provides an appropriate basis from which to analyse the effects on the business cycle of balanced changes in the structure of taxation. It is shown that, under certain shifting assumptions, increases in the taxation of wages or profits will stimulate investment and attenuate the amplitude of the business cycle. Ultimately, the shifting of taxes reduces to a conflict over income shares. The changing distribution of income in the United Kingdom in recent years suggests that investment is likely to remain sluggish unless there is a significant reversal of income shares. This may give rise to increasing economic and political tensions into the 21st century.     

What is the systems perspective to Innovation and Technology Policy(ITP) and how can we apply it to developing and newly industrialized economies?

Despite recent advances in the Evolutionary and Systems Perspectives to Economic Change (SI), confusion still exists about how to apply it to the design and implementation of Innovation & Technology Policy (ITP) in concrete settings. Since the ‘Normative’ aspects of SI are framed in terms so general to make them insufficient or inadequate as guides and tools for actual policymaking, a presumption exists that additional theoretical and conceptual knowledge is required. Thus a major objective of this paper is to contribute to the development of a realistic and ‘grounded’ theoretical framework for Technology and Innovation Policy which is particularly relevant both for the promotion of Business Sector R&D and of hi tech (especially IT) industries in Top Tier and other Industrializing Economies. A second objective is to contribute directly to the capability of successfully applying this conceptual framework in concrete policy settings. Rather than justifying ITP the paper focuses on characterising and applying “Salient Normative Principles or Themes” of the SI perspective to ITP. Several concrete examples are given and the notions of Policy Process, (Country) Program Portfolio Profile and Policy Environment are introduced.     

A resource-based view of Schumpeterian economic dynamics

This paper seeks to offer a theoretical platform where the modern “resource-based view” of the firm might meet with evolutionary economics and the study of entrepreneurship, and with the economics of industrial organization. It does so by proposing the concept of the “resource economy” within which productive resources are produced and exchanged between firms. This is presented as the dual of the mainstream goods and services economy – where the “resource economy” captures the dynamic capital structure of the economy. The paper is concerned to bring out the distinctive principles governing resource dynamics in the resource economy, capturing competitive dynamics in such categories as resource creation, replication, propagation, exchange and leverage; evolutionary dynamics in terms of resource variation, selection and retention; entrepreneurial dynamics in terms of resource recombination and resource imitation, transfer and substitution; and industrial organizational dynamics in terms of resource configuration, resource complementarities and resource trajectories.     

Economic policy making in evolutionary perspective

Economic policy making is discussed from three different angles: the political economy of actual policy making (“what policy does do”), the analysis of policy instruments for given ends (“what policy could do”), and the debate on policy goals and their legitimization (“what policy ought to do”). Center stage in the evolutionary perspective is new, positive and normative knowledge which is unfolding during the policy making process and in its aftermath. It is argued that this implies regularities and constraints which extend and modify the comparative-static interpretations of public choice theory, economic policy making theory, and social philosophy.

Regulation of the evolution of the architecture of a network by tensors operating on coalitions of actors

Socio-economic networks, neural networks and genetic networks describe collective phenomena through constraints relating actions of several actors, coalitions of these actors and multilinear connectionist operators acting on the set of actions of each coalition. We provide a class of control systems governing the evolution of actions, coalitions and multilinear connectionist operators under which the architecture of the network remains viable. The controls are the “viability multipliers” of the “resource space” in which the constraints are defined. They are involved as “tensor products” of the actions of the coalitions and the viability multiplier, allowing us to encapsulate in this dynamical and multilinear framework the concept of Hebbian learning rules in neural networks in the form of “multi-Hebbian” dynamics in the evolution of connectionist operators. They are also involved in the evolution of coalitions through the “cost” of the constraints under the viability multiplier regarded as a price.     

Schumpeter and the `Schmollerprogramm': integrating theory and history in the analysis of economic development

This essay addresses the historical and institutional aspects of Schumpeter's thought. It suggests that Schumpeter prepared a pluralist research agenda, formulated in accordance with the conceptual perspective of the German Historical School, as presented by major scholars such as Schmoller, Sombart, Spiethoff and Max Weber. Schumpeter's notion of development, with its emphasis on the correspondence of economic and socio-cultural evolution, is therefore to be viewed in the context of the comprehensive Schmollerian approach. Moreover the ethical-evolutionary components of Schmoller's ideas point at the vital role of the German Historical School in the elaboration of a modern evolutionary economics in Schumpeterian terms. The essay concludes that the Schmollerprogramm is going to inspire further developments in Schumpeterian economics, as the integration of theory and history continuously marks the research agenda of evolutionary approaches to economic development.     

Endogenous structural change and crisis in a multiple time-scales growth model

The slow and endogenous twist of economic macro-structure makes up an important evolutionary feature of capitalist economies, and may be at the root of structural crisis. In this line, a Goodwinian growth model with increasing returns and profit-sharing that tries to picture a simple scenario of the seventies crisis is considered. It is shown that the exhaustion of the Kaldor-Verdoorn “productivity law” can entail, in a nonlinear framework, a “catastrophic” bifurcation from a “high” to a “low” growth path. Slow/fast dynamical systems then allow one to formalize a multiple time-scales dynamics where the growth path is shaped by the structural framework in which it takes place, but has also a long -un feedback. Structural change and crisis appear as long term and endogenous outcomes.     

Equilibrium uniqueness with perfect complements

The present note analyzes the simultaneous ascending-bid auction with arbitrarily many asymmetric bidders with decreasing marginal valuations under complete information. We show that the game is solvable by iterated elimination of weakly dominated strategies if the efficient allocation assigns at least one unit to every player and if bid increments are sufficiently small. In that unique equilibrium, bidders immediately reduce their demand to the efficient allocation, and the auction ends in the first round of bidding.We would like to thank seminar participants at UC Davis, in particular Klaus Nehring and Louis Makowski for comments.

Multimarket contact and inter-firm cooperation in R&D

Research joint ventures (RJVs) have been widely acclaimed for their alleged ability to restore private incentives to undertake R&D. Economists have, however, also sounded the alarm concerning the opportunities RJVs may create for collusion between partners. The danger of anti-competitive behavior increases significantly when repeated R&D collaboration occurs between firms that also “meet” in many product markets. This phenomenon is shown to be present in a large set of U.S.-based RJVs. The question is about the incentive trade-off: Are the alleged advantages of RJVs in terms of enhancing incentives for R&D sufficient to overcome the potential disadvantages in terms of decreasing incentives for R&D due to simultaneous multiproject and multimarket contact? Significant foreign participation, high technological and market uncertainties, and the set up of “porous” RJVs may operate as a check to anti-competitive behavior.     

Menger’s causal-realist analysis in modern economics

Carl Menger pioneered a unique theoretical research method which served as the foundation of the early Austrian school of economics. Menger’s causal-realist analysis was revived and formalized just before and after World War 2 by Ludwig von Mises as the “praxeological method.” Murray Rothbard, a student of von Mises’, utilized the method in formulating a comprehensive system of economic theory in his treatise, Man Economy, and State published in the early 1960s. Rothbard’s treatise became the foundational work for the “Austrian revival” in the 1970s. In this paper, we address several issues related to the role of Menger’s method in modern economics. First, ample evidence is adduced that von Mises and Rothbard each expressed a surprising ambivalence with respect to his own work in relation to the early Austrian school. Second, von Mises viewed Rothbard’s treatise as beginning a new epoch in economic theory. Third, contrary to the conventional view, a careful analysis of his treatise shows that Rothbard drew heavily on the contemporary neoclassical literature in developing his theoretical system and that his intent was never to set up a heterodox movement to challenge mainstream economics. Rather, his main aim was to consistently apply the praxeological method to rescue economics from what he considered the alien methodology of positivism, which was imported into economics after World War 2. Lastly, I will tentatively suggest that the term “Austrian economics” as the designation for the intellectual movement that coalesced in the early 1970s may now have outlived its usefulness. This term, which initially served an important strategic purpose in promoting the revival of the broad Mengerian tradition, may have come to obscure the meaning and importance of the praxeological research paradigm that Menger originated.     

A close eye on the invisible hand

The paper shows how, and under what minimal information supply conditions, a market finds its competitive equilibrium price and thus solves the so-called tatonnement process, without sellers and buyers knowing the equilibrium price in advance. The information premises must be understood as a basic first approach, and do not necessarily mimic the real market process. Demonstration of a discovery process under these information handling conditions is an important finding for an evolutionary market theory. Additional information-processing elements should augment the efficiency of the discovery process. The results of the simulated market process set out above raise new questions. The role of institutional elements (such as the relevance of demand flexibility or “certainty” of knowledge in the learning process, etc.) is discussed further outside the context of the simulation model, providing new insight into the market process.     

A comparison of diffusion approximations and actual limits in birth and death processes of noisy evolution

The stationary distribution of a birth and death process may not be approximated by a diffusion. The general situation is illustrated on the “musical chairs” model by Binmore et al. (1995). This model is shown to generate outcomes which are not captured by the concept of the ultralong run equilibrium selection introduced in Binmore et al. (1995).     

Different employment of capitals in vertically integrated sectors: Smith after the Austrians

The Austrian notion of stages of production and the related principle of the greater productivity of roundabout methods, plus the neo-Austrian notions of vertical integration and vertical division of labour, are utilized in this paper in an attempt to reconstruct Smith’s convoluted arguments on the different employment of capitals in chapter 5, book 2, of the Wealth of Nations. Smith’s arguments are first clarified in the light of the two concepts of capital (money capital and productive capital), of the two aspects of productive labour (living labour and dead labour) and of the two viewpoints (of an individual and of society) on which Smith’s theory is based. The results of this clarification are then used to prove that, independently of Smith’s own words but in consistency with his theory, the notions of “quantity” and “productivity” of productive labour have a “vertical”, as well as a “horizontal”, dimension so that they fit both the input–output scheme and the Austrian framework of time-consuming methods of production.     

Knowledge of growth and the growth of knowledge

The central theme of this address is the complicated relationship between the growth of the economy and the growth of knowledge. This theme is explored with the help of a single concept “restless capitalism” which is used to capture the idea that capitalism in equilibrium is a contradiction in terms precisely because the growth of knowledge cannot be meaningfully formulated as the outcome of a constellation of equilibrating forces. This theme is explored through a discussion of growth accounting, the relationship between innovation, markets and institutions and, as an example, the development of innovation in the field of ophthalmology. We also discuss some pioneering contributions made by Simon Kuznets and Arthur Burns to the discussion of evolutionary growth. From this Schumpeterian perspective we see the economy as an ensemble not an aggregate entity and so see more clearly the importance of microdiversity in the relationship between growth of knowledge and growth of the economy.
