This paper contributes to the debate surrounding the question of whether biotechnology, particularly its applications in agricultural and food-related industries, should be regarded as revolutionary or evolutionary (with some reservations about the vaildity of teh question). The potential to create a revolutionary techno-economic paradigm shift does exist but it is currently systems. It is also important to consider the motivations underlying statements about the revolutionary/ evolutionary nature of biotechnology, as some such statements are intended to influence events rather than to reflect them. The impact of small firms on the direction and place of revolutionary change in these industries is likely to be marginal, unlike the situation in the early phases of teh electronics/IT revolution. At present the lack of integration of policy initiatives by national governments and the EC is a major factor discouraging the rapid implementation of change.  相似文献

In recent years there has been a growing belief that materials constitute a generic technology of revolutionary significance, ranking alongside information techno- logy and biotechnology. Our main aim is to examine the plausibility of this claim. In so doing we indicate what is distinctive about changes i n materials science and technology, and report on recent forecasts of potential change. Our second aim is briefly to discuss corporate and public policy on materials innovation i n a number of advanced countries. We present some preliminary jindings from interviews conducted with prominent UK materials producers and users. We conclude that there have been some important incremental and radical innovations i n materials technology. But because the diffusion of innovative materials and processes into different industry sectors and products has been uneven, i n terns of their current and likely future impact on the economy as a whole these changes cannot yet be described as revolutionary. The future impact of materials technology will depend not just on the materials innovation strategies of companies and governments, but on their ability to overcome users' conservatism and to convince them of the design and quality improvements that are possible.  相似文献

Evolutionary economics and economic geography   总被引:19,自引:0,他引:19  
This article attempts to explore how key notions from Evolutionary Economics, such as selection, path-dependency, chance and increasing returns, may be applied to two key topics in Economic Geography. The first issue is the problem of how to specify the (potential) impact of the spatial environment on new variety in terms of technological change. Evolutionary thinking may be useful to describe and explain: (1) the process of localized `collective' learning in a regional context, (2) the adjustment problems that regions may be confronted with in a world of increasing variation, and (3) the spatial formation of newly emerging industries as an evolutionary process, in which the spatial connotation of increasing returns (that is, agglomeration economies) may result in a spatial lock-in. The second issue is the problem of how new variety may affect the long-term evolution of the spatial system. We distinguish three approaches that, each in a different way, apply evolutionary notions to the nature of spatial evolution. This is strongly related to the issue whether mechanisms of chance and increasing returns, rather than selection and path-dependency, lay at the root of the spatial evolution of new technology.  相似文献

Counterfactual conditional statements are ubiquitous in any scientific endeavour. This paper contains an analysis of the nature of counterfactual conditionals and the conditions under which they are considered assertable by scientists. The paper then applies this analysis to the use of counterfactuals in evolutionary economics, arguing that because evolutionary economics is inherently concerned with historical processes it cannot avoid the use of counterfactual history as one of its tools of empirical analysis. We discuss the strengths and pitfalls of counterfactual history. We argue that because evolutionary economics starts from the foundation that randomness may be inherent in any economic system, the very aspects of evolutionary economics that make counterfactual history a desirable empirical tool also make that tool difficult to employ.

Growing environmental concerns, emerging economies, and the strong uncertainties about future prices of fossil fuels as well as about CO2 emissions contribute to a potential renaissance for biorefining industries. According to theories on technology shifts and innovations (e.g. [Utterback, J. M. 1994. Mastering the dynamics of innovation. How companies can seize opportunities under technological change. Harvard Business School Press]), heavy process industries like pulp and paper tend to be rigid towards disruptive innovations and instead focus on incremental innovations and economies of scale. However, a major empirical contribution from this case study demonstrates that some incumbents may escape the lock-in and form a new biomass development block. The study also contributes to academic as well as technology and innovation management perspectives in process-based and natural resource-based industries, where process innovations are tightly coupled with product innovations in inter-industry (vertical) linkages, the so-called development block.  相似文献

Contrary to most writings in the field of evolutionary economics which have a strong microeconomic flavor, here amacroeconomic evolutionary model will be presented in order to deal with themacroeconomic employment effect of technical change where there is just one old and one new technology. Several authors who favour an evolutionary approach to the theory of technical change share an optimistic view with respect to the macroeconomic employment effect of technical change. In the paper we are dealing with the question of whether this optimistic view is a necessary result of an evolutionary approach to technical change or rather of some other characteristic of the models used. It is shown that the evolutionary approach to technical change is not inherently optimistic or pessimistic with respect to the employment effects. Rather it is the labour market behaviour that will decide, whether the employment effects of technical change are positive, negligible or even negative.  相似文献

Scholars have long debated the ‘revolutionary’ character of the ‘Marginal Revolution’ in economics, focusing on theoretical foundations, methodological devices, social context and political aspects. This article offers a new perspective by investigating ontological and epistemological conditions of that intellectual movement. This requires, in turn, a characterization of those conditions, for which purpose we will draw on Foucault's configurations of thought into ‘epistemes’ in The Order of Things. Although not mentioning those conditions, there have been few references in economics to Foucault's approach. They have mainly claimed that he neglected its importance because he did not see it as a ‘revolution’ in The Order of Things. It is argued here that he actually considered it a ‘revolution’ in The Archaeology of Knowledge. A revision of Foucault's account provides some ideas regarding deep philosophical conditions of the emergence of neoclassical theory and defies some usual interpretations of the circumstances that led to the mathematization of economics. The main conclusion is that its revolutionary character did not stem from a change of ontological beliefs, but—just as many historians of economics have defended—it was a methodological revolution. This study suggests a reinterpretation of that event, claiming that it resulted from a new conception of language and a crisis of Descartes's project of a mathematical unifying science. Going beyond that debate, these reflections proffer ideas that deserve an appraisal in economics.  相似文献

This paper deals with some results of an extended investigation which was carried out by the German Institute of Economic Research, Berlin, and the Ifo-Institute, Munich, and financed by the Stiftung Volkswagenwerk. For 29 sectors of manufacturing Cobb-Douglas production functions have been calculated, based on quarterly figures 1958–1968 of value added, input of hours worked, input of utilized capital stock (net of scrappage), and of potential value added, potential labor input and total capital stock. The income distribution is used as production elasticities. For each of the 29 sectors 12 time series of quarterly indices of total factor input and technical change have been computed, using utilized data (variation 1-6) and capacity data (variation 7-12). Two different time series of α are used, taking quarterly interpolated data (variation 1, 3, 5, 7, 9, 11) and the geometric mean 1958–1968 (variation 2, 4, 6, 8, 10, 12). Moreover three different parameters of homogeneity are introduced, taking r= 1 (variation 1, 2, 7, 8), r= 1.1 (variation 3, 4, 9, 10) and r= 1.25 (variation 5, 6, 11, 12). Seven of the 29 sectors show a very high sensitivity of the rate of technical change due to the assumed r, six sectors a rather high sensitivity. Ten of the 29 sectors show a rather small sensitivity of technical change due to the assumed r, six sectors a very small or even negative sensitivity, i.e. an increasing r creates an increasing technical change. These results can be explained by taking account of the fact that total factor input in many branches increased very slowly or even decreased (labor input alone decreased in nearly all branches). A hierarchy of technical change has been calculated; this hierarchy is difficult to explain, because fast growing industries as well as industries with a small or a negative growth rate of output rank in both the leading and the last group of technical change. Very high rates of output result in high rates of technical change (chemicals, mineral oil refining, plastics manufactures), but some industries with a rather small growth of output (shipbuilding, fine ceramics, steel drawing, and cold rolling mills) show a high rate of technical change too.  相似文献

Can changes in industry structure be characterized by movements towards a long-run concentration ratio (CR)? This paper estimates an error correction model for 33 industries in India for the period 1974–85, using nonlinear estimation methods. The results indicate that structural change in India is composed both of significant changes towards the long-run CR and of significant changes of the long-run CR. The adjustment towards the long-run CR seems to be faster in India than in most Western studies. In spite of this, it is below 0.5 in most industries, indicating that even after 11 years, all the difference between actual and long-run CRs is not eroded and ‘excess’ market shares persist in most industries. Across industries, speeds of adjustment are higher in industries with high profit margins and lower in industries which are reserved for the public sector.  相似文献

This paper here proposes a theory of classification and evolution of technology based on taxonomic characteristic of interaction between technologies that is an under-studied field of research in economics of technical change and management of technology. The proposed classification of technologies, in a broad analogy with evolutionary ecology of parasites, within a theoretical framework of Generalised Darwinism, is: (1) parasitic technologies, (2) commensal technologies, (3) mutualistic technologies, (4) symbiotic technologies. This theory here suggests the property of mutual benefaction from interaction between different technologies and the theorem of not independence of any technology to explain and predict characteristics and evolutionary pathways of technologies over time. Overall, then, this study may be useful for bringing a new perspective in economics of innovation to categorise and analyse the interaction between technologies that can be a ground work for development of more sophisticated concepts to explain and predict the evolution of technology and generalise aspects of technological change in human society.  相似文献

This paper examines the effect of the information content of Federal Open Market Committee (FOMC) statements on the level and volatility of Treasuries and stock returns. Statements are separated into “informative” and “uninformative” groups with informative statements delivering important information which was not previously anticipated by the consensus. We find evidence that the information content of FOMC statements tends to generate an asymmetric response, with informative statements having a larger effect than uninformative statements. Asymmetries tend to be more pronounced for the conditional mean than conditional volatility. The behavior of volatility is tent‐shaped, spiking during policy announcements and declining before and after the release. We also find that the evolution of the language of the FOMC statements does matter to market participants and that joint releases of target rate changes and informative statements have a distinctly more pronounced impact than other types of announcements.

Accounting for economic evolution: Fitness and the population method   总被引:4,自引:1,他引:3  
The theme of this paper is the general population dynamics of evolutionary processes, and, in particular, a number of accounting concepts that are central to any understanding of evolutionary processes of the variation-cum-selection retention kind. A population perspective, for example, turns out to be crucial to the study of the competitive process in economic systems defined at the level of industries, sectors and markets. Business rivalry, underpinned by differential innovative activity, is the basis of the differential survival and growth of competing economic activities and the strategies deployed to create sustainable differences in competitive selection characteristics are at the core of the capitalist dynamic interpreted as an adaptive, evolutionary process. This kind of evolutionary argument is necessarily concerned with growth rate dynamics and the explanation of the diversity of growth rates across entities in a population. However, the following discussion does not provide any causal explanation of economic evolution in terms of the determinants of growth rate differences, rather it provides a bookkeeping scheme in which different causal theories may be set and compared. Growth dynamics and structural change are the two central features of variation/selection processes within populations and I explore them in terms of three themes: namely, Logistic Growth Accounting; Competition Accounting; and, the Price Theorem. The unifying theme that links all three is their relation to the population method in evolutionary theory.   相似文献

This article analyses financial markets’ reaction to European Central Bank's (ECB) communication. We apply a novel indicator that quantifies the contents of the ECB's introductory statements and allows disentangling ECB statements on prices, the real and the monetary sector. We provide evidence that it matters what issue the ECB is speaking about: especially, the ECB's statements on price developments represent important news to financial markets. It also matters when the ECB affects markets: communication drives maturities above 4 months.  相似文献

How does FDI affect China? Evidence from industries and provinces   总被引:3,自引:0,他引:3  
Using the latest panel data from 19 industries and 30 provinces in China, we found it is not true that more FDI necessarily brings about more output growth across the board. Local industries without foreign participation lose while those with some participation gain from the inflow. Provinces in western and central regions lose while those in the eastern and coastal regions appear to be the major beneficiaries. While the net effect of FDI is still positive, the regional disparity has been growing. It casts doubt on the rationale of haphazard and lavish policies to compete for FDI in China.

Darwinism is shown possible to generalize fruitfully to help comprehend economic change by drawing on evolutionary developmental biology (“evo–devo”)—its recent version, less concerned with replication of genes than with genomic instructing of development of organisms. The result is a conceptual model with multilevel applications, generalizing development as instructed self-organizing with inputs from environments, and evolution as experimental search for instructions making the development successful. Its economic interpretation suggests to unite several existing fields into evolutionary developmental economics, where economic change can be studied comprehensively as development instructed by actual institutional rules, intertwined with the evolution of these rules.  相似文献

Although the empirical pattern of industry shakeout has been documented for many manufacturing industries, we know little about the processes by which market structure evolves in non-manufacturing service industries. This paper establishes detailed empirical observations about the consolidation of a single non-manufacturing industry, the wholesale distribution of pharmaceuticals. These observations are used to explore differences between manufacturing and wholesaling in both the patterns and explanations for consolidation and analyze the explanatory power of theories that link consolidation to technological change. The analysis demonstrates that theories developed to explain consolidation in new manufacturing industries have varying degrees of applicability to the consolidation of drug wholesaling. The observed patterns of exit, innovation, and growth suggest important modifications to evolutionary theories of market structure.  相似文献

We measure the effective assistance to 24 Norwegian private industries in 1989 and 1991 from government budgetary subsidies, indirect commodity taxes, import protection through nominal tariffs and non-tariff barriers, and electricity market distortions. The assistance effects are measured by the change in the net-of-tax value added price due to a removal of the policy measures considered. Most industries were effectively assisted, but the effective assistance differs widely between industries, indicating the overall distortive effect on the industry structure. Agriculture, Food Processing and Manufacture of Beverages and Tobacco stand out as the most assisted industries. Budgetary subsidies and non-tariff barriers had the strongest effective assistance effect.  相似文献

Evolutionary targeting   总被引:1,自引:1,他引:0  
Evolutionary Targeting is a dynamic, systems-evolutionary policy perspective which focuses on triggering, re-enforcing and sustaining market-led evolutionary processes of emergence of Multiagent Structures (industries, clusters, markets, etc). A major aspect is leveraging existing successes in firms to promote emergence of such structures. This requires discrete policy interventions directed at varying areas of system/market failure, which make their appearance at difference phases of the overall process. The paper briefly illustrates the approach through an analysis of VC policies in Israel and selected European countries, and by referring to the traditional view of Infant Industry development and existing views on high tech cluster development. The resulting framework of analysis, which differs radically from the ‘Picking Winners’ policies of the past and from the successful targeting of infant industries in Korea and post war Japan, seems to fit the increasingly turbulent and high return/high risk global environment prevailing today.

Bioeconomics as economics from a Darwinian perspective   总被引:2,自引:2,他引:0  
Bioeconomics—the merging of views from biology and economics—on the one hand invites the 'export' of situational logic and sophisticated optimization developed in economics into biology. On the other hand, human economic activity and its evolution, not least over the past few centuries, may be considered an instance for fruitfully applying ideas from evolutionary biology and Darwinian theory. The latter perspective is taken in the present paper. Three different aspects are discussed in detail. First, the Darwinian revolution provides an example of a paradigm shift which contrasts most significantly with the 'subjectivist revolution' that took place at about the same time in economics. Since many of the features of the paradigmatic change that were introduced into the sciences by Darwinism may be desirable for economics as well, the question is explored whether the Darwinian revolution can be a model for introducing a new paradigm in economic theory. Second, the success of Darwinism and its view of evolution have induced economists who are interested in an evolutionary approach in economics to borrow, more or less extensively, concepts and tools from Darwinian theory. Particularly prominent are constructions based on analogies to the theory of natural selection. Because several objections to such analogy constructions can be raised, generalization rather than analogy is advocated here as a research strategy. This means to search for abstract features which all evolutionary theories have in common. Third, the question of what a Darwinian world view might mean for assessing long term economic evolution is discussed. Such a view, it is argued, can provide a point of departure for reinterpreting the hedonistic approach to economic change and development. On the basis of such an interpretation bioeconomics may not only go beyond the optimization-cum-equilibrium paradigm currently prevailing in economics. It may also mean adding substantial qualifications to the subjectivism the neoclassical economists, at the turn of the century, were proud to establish in the course of their scientific revolution.  相似文献
