Conventional economic reasoning begins with the definition of Scarcity , then assumes the existence of a " Rational Agent " bent solely on the attainment of one goal — the maximization of her/his welfare as defined by that agent. The scheme of valuation (" Preference s" or "tastes") used by the decision-maker is also assumed to be constant and native to the agent (" Independent Preferences "). Given the foregoing stipulations, the determination of the " Rational Choice " for any agent becomes a straightforward exercise in the Differential Calculus . Evolution ary economics derives from a more modern tradition of inquiry, which does not take the characteristics of either the objects of choice or of the decision-maker as fixed. It challenges the Newton ian worldview in economics in the similar manner, as it was challenged by Darwinian Evolutionary Theory in Biology and by studies of Self-organization in Physics . PREDECESSORS OF EVOLUTIONARY ECONOMICS Karl Marx began in the mid- 19th Century with his schema of stages of historical development, by introducing the notion that " Human Nature " was not constant and was not determinative of the nature of the Social System ; on the contrary, he made it a principle that Human Behavior was a function of the social and Economic System in which it occurred. At approximately the same time, Darwin developed a general framework for comprehending any process whereby small, Random Variation s could be accumulated over time and under the urgings of economic forces into large-scale changes that resulted in the emergence of wholly novel forms (" Speciation "). This was followed shortly after by the work of the American pragmatic philosophers ( James , Peirce , Dewey ) and the founding of two new disciplines, Psychology and Anthropology , both of which were oriented toward cataloging and developing explanatory frameworks for the variety of Behavior Pattern s (both individual and collective) that were becoming increasingly obvious to all systematic observers. The state of the world converged with the state of the evidence to make almost inevitable the development of a more modern framework for the analysis of substantive economic issues. " due to John Dewey, with whom Veblen was to make contact briefly at the University Of Chicago . The most important works by Veblen include, but are not restricted to, his most famous works (''Theory of the Leisure Class''; ''Theory of Business Enterprise''), but his monograph ''Imperial Germany and the Industrial Revolution'' and the essay entitled ''Why is Economics not an Evolutionary Science'' have both been influential in shaping the research agenda for following generations of Social Scientist s. TOLC and TOBE together constitute an alternative construction on the neoclassical marginalist theories of consumption and production, respectively. Both are clearly founded on the application of the "Veblenian dichotomy" to cultural patterns of behavior, and are therefore implicitly but unavoidably bound to a critical stance; Veblen's theories cannot be well understood unless one grasps that the dichotomy is at its core a valuational principle. The ceremonial patterns of activity are not bound to just any past, but rather to the one that generated a specific set of advantages and prejudices that underlie the current structure of rewards and power. Instrumental judgments create benefits according to an entirely separate criterion, and therefore are inherently subversive. This line of analysis was more fully and explicitly developed by Clarence E. Ayres of the University Of Texas At Austin from the 1920s . Equilibrium , which is something like "the normal mode of economic affairs". This equilibrium is being perpetually destroyed by Entrepreneur s who try to introduce Innovation s. A successful introduction of an innovation disturbs the normal flow of economic life, because it forces some of the already existing technologies and means of production to lose their positions within the economy. Kenneth Boulding was one of the advocates of the evolutionary methods in social science, as is evident from Kenneth Boulding's Evolutionary Perspective . Kenneth Arrow , Ronald Coase and Douglass North are some of the Bank Of Sweden Prize In Economic Sciences In Memory Of Alfred Nobel winners who are known by their sympathy to the field. PRESENT STATE OF DISCUSSION One of the major contributions to the emerging field of evolutionary economics has been the publication of 'An Evolutionary Theory of Economic Change' by Richard Nelson and Sidney Winter . These authors have focused mostly on the issue of changes in Technology and Routine s, suggesting a framework for their analysis. If the change occurs constantly in the economy, then some kind of evolutionary process must be in act, and there has been a proposal that this process is Darwinian in nature. Then, mechanisms that provide Selection , generate Variation and establish Self-replication , must be identified. It has been proposed that Market s act as the major Selection Vehicle s. As Firm s compete, unsuccessful rivals fail to capture an appropriate Market Share , go Bankrupt and have to exit. The variety of competing firms is both in their products and practices, that are matched against markets. Both products and practices are determined by routines that firms use: standardized patterns of actions implemented constantly. By imitating these routines, firms propagate them and thus establish inheritance of successful practices. The Darwinian-based evolutionary approach has been criticized through indication that there is no mechanism in evolving economic entities that could correspond with the complex interactions of organisms’ genetic and phenotypic sphere. Unlike in biology, no separation exists between what could be analogue to genotypic level and phenotypic level, and there is no sufficient inertia in the ‘unit of inheritance’ for social behavior as is with ‘germ plasm’ of genes. Also, variation and selection occur in a less constrained form allowing greater degree of freedom compared to that of biological evolving entities. Ulrich Witt has proposed that an appropriate tool set for socio-economic evolution analysis is provided by the range of Self-organization and Complexity Theories , that deal with phenomena of Emergence and increasing complexity. As Philip Mirowski has demonstrated in his book 'More Heat than Light', the first 200 years of economic theory was modeled primarily on Physics — economic terminology like " Labour Force ", " Equilibrium ", " Elasticity ", and " Velocity Of Money ", are no accident. AXIOMATIZATION OF EVOLUTIONARY ECONOMICS A number of authors have aimed to outline common features of evolutionary schools in economics. In particular, such attempts were made by Axiomatics could be built on three propositions:
Ideas are articulated in Language and thus transported into the social domain. Generic ideas, in particular, can bring about cognitive and behavioral processes, and in this respect they are practical and associated with the notion of ‘productive Knowledge ’. It is generic ideas that evolve and form causal powers underlying the change. Evolutionary economics is essentially about changes in generic knowledge, and involves transition between actualized generic ideas. Actual phenomena, being manifestations of ideas, are seen as ‘carriers of knowledge’. Three analytical concepts corresponding to ontological axiomatics are thus:
The latter implies that no law that could apply universally in space and time, could be formulated. Instead, a ‘variable law’ (in terms of Charles Peirce ) could be speculated about, that is a generic idea that shapes the social dynamics but changes over time. The logic of the invariant of evolutionary process in social science is seen as the following sequence, described as an ‘ evolutionary regime’:
Thus, evolutionary process is essentially Irreversible , and it is seen as a transition from one state of generic idea dominance to another. Evolution represents a genealogy of regimes, that come into existence through adoption by populations of economic agents. This can be achieved either through Darwinian evolution (as considered by Nelson and Winter), or through emergence of ‘critical masses’ as suggested by Witt . Thus, evolutionary economics is concerned with the transformation of generic ideas, or social and technical knowledge, that determine states of socio-economic system, and dominating economic phenomena (products, technologies, institutional arrangements) within these. Every possible state, form and determining idea is a passing one, but its emergence is no occasion, it is guided by the logic of evolutionary laws. SEE ALSO
