Adam Smith's invisible hand metaphor (IH) is examined in light of two different accounts of the origin of traits: Charles Darwin's theory of evolutionary optimization and William Paley's theory of divine intervention. Smith's stand supersedes both accounts. For Smith, intermediating drives, such as the sexual one, neither arise accidentally and favored according to their fitness à la Darwin nor planted by the Deity à la Paley. For Smith, such drives are adopted in light of their ultimate end. Smith did not provide an account of how the drives are connected to their far-reaching, invisible beneficial ends or why do agents become dimly aware of that causality.  相似文献

Recent biomedical research shows that roughly three-quarters of cognitive abilities are attributable to genetics and family environment. This paper presents a growth model that characterizes the role of the intergenerational transmission of genes and the effect of family environment on growth trajectories. If the average human or physical capital stocks are sufficiently low, the model shows that the economy will be caught in a poverty trap. Conversely, countries with more resources will converge to a bala nced growth path where the average rate of genetic transmission of skills from parents to children determines the long-run rate of output growth. Increased genetic diversity (or income inequality) is shown to raise the fertility rate and reduce output growth in the transitional dynamics. Thus, nature and nurture are able to explain a variety of countries' growth experiences.  相似文献

An evolutionary model of the size distribution of firms   总被引:2,自引:0,他引:2  
An analytical study of the evolution of the distribution of firm size in an industry is presented. A drift-diffusion model is proposed to express the time-evolution of density of firm size within the industry. The model blends the conventional, more or less static, determinants with the kinds of dynamic considerations introduced by stochastic processes of evolutionary dynamics. The steady-state distribution as well as the dynamic behavior of the model are derived. Parameters in the resulting analytical expressions are then fit to a population of firms in the non-manufacturing service sector. The empirical portion of the paper validates the proposed evolutionary model.  相似文献

Technology transfer in United States universities   总被引:10,自引:0,他引:10  
This paper examines the role of offices of technology transfer (OTT) in 12 U.S. universities in 1998 in commercializing research results in the form of patents, licenses, and start-ups of new companies. We study the organization and place of OTTs within the university structure, the process of technology transfer, and the staffing and funding of the office. Data were collected through a mail questionnaire followed up through telephone interviews. We also conducted a statistical analysis of data for 170 U.S. universities, hospitals, and research institutes for the period 1991–1996. Our findings suggest that technology transfer from universities to the commercial sector needs to be understood in its broader context. The primary purpose of a technology transfer program is for the university to assist its researchers in disseminating research results for the public good. Success in this endeavor is only partially reflected in income generated for the university or the number of business start-ups. The degree of success depends not only on the nature of the interface between the university and the business community but also on the receptivity in the surrounding community as well as the culture, organization, and incentives within the universities themselves.  相似文献

This paper examines the `learning economy' from the perspective of occupational characteristics and changes in the British labour market between 1980 and 1992. Following a discussion of the learning and knowledge economy, cross-sectional employment data are analysed to ascertain which occupations can be classified as knowledge-based. Longitudinal career history data are then used to trace the flows of these `knowledge workers' over time. Sectoral shifts are examined, with a particular focus on the knowledge-intensive service sectors. The data come from the Employment in Britain survey: a large-scale employee survey from 1992. The approach used allows us to measure somewhat intangible aspects of economic behaviour such as learning and tacit knowledge and attempt to trace their flows. Shifts in knowledge from the manufacturing to the service sector are shown to be important and related to previous work which demonstrated the importance of knowledge intensive business services for both output and productivity in manufacturing.  相似文献

Should government subsidize R&D and does it matter how these subsidies are allocated? We examine these questions in a dynamic model where R&D is described as sequential sampling from a distribution of new ideas. Successful discoveries affect future available resources and incentives for further R&D. Consequently, there may be under-investment in R&D. We study the effect of government interventions aimed at fostering growth through R&D. Calibrating the model with aggregate data from the Israeli business sector allows us to quantitatively compare two forms of support resembling those actually used to encourage R&D in the Israeli business sector: (i) an unrestricted subsidy that may be used at the recipients' discretion to finance R&D or other investments, (ii) a subsidy earmarked by the government for R&D activities only. While there is no theoretical way to determine which of the two subsidies will have a greater impact on search for new ideas and growth, we find that in the calibrated economy both subsidies have a significant but similar impact on the economy's output and TFP growth rates. Accordingly, in the case of the Israeli business sector, the incentives to conduct R&D were sufficiently strong, and no R&D-specific encouragement was needed. However, a sensitivity analysis reveals that for economies characterized by other parameter values this result may not be true. Correspondence to: B. Bental  相似文献

Theoretical perspectives on strategic environmental management   总被引:1,自引:1,他引:0  
Strategic Environmental Management (SEM) incorporates into firms' core strategies the transformation of products and processes that they believe an environmentally concerned society will increasingly demand. Significant threads have to do with the discovery of cost savings and market opportunities from reducing environmental impacts. SEM, like the environmental regulation hypothesis associated with Michael Porter, implies that society's efforts to reduce external environmental costs often lead to identification of hitherto-ignored or undeveloped profit possibilities. This would be surprising from the standpoint of neoclassical economic theory, to the extent that SEM utilizes available information about the potential costs and benefits of projects. Within the framework of evolutionary, capabilities-based theories of the firm, however, this discovery and its exploitation in SEM make perfect sense. Capabilities theory would imply that firms' intrinsic path dependence may previously have obscured such opportunities. This paper examines the theory of SEM, its implications for neoclassical and capabilities theories of the firm, and survey results drawn from the author's work with member companies in a regional pollution prevention roundtable. RID="*" IDI have enjoyed the able and insightful research assistance of Justin Vernon. Cooperation from the companies that participated in the survey, and financial support from Allegheny College and its Center for Economic and Environmental Development, are gratefully acknowledged. Reviewers for this journal provided numerous, valuable suggestions. Responsibility for the material herein remains mine alone.  相似文献

This paper examines the diffusion of digital switches from 1983 to 1996. It expands upon the existing literature by extending the data available back an additional six years and by adding independent companies such as Frontier, SNET and Cincinnati Bell. The data (graciously provided by DataQuest) indicate that the early period of adoption, which previous papers have been unable to examine due to lack of data, is significantly different than the later period of adoption. In the early period the installed base and the ability of larger networks to internalize more of the total benefits are the primary determinants of adoption, while the distribution of population becomes important in the later period as firms finish building out their densest areas. Overall, independents adopted earlier than the RBOCs, although this difference appears to be driven by the fact that independents were still using primarily electromechanical switches in 1983, while RBOCs had already invested heavily in analog technology. The data suggest that new technologies such as internet telephony will be adopted most rapidly by newly built networks such as Qwest and Level 3.  相似文献

This paper examines the rapid growth of the polymer-based and biomedical clusters in Ohio and Sweden – two regions of similar size and with similar traditions undergoing similar industrial restructuring. Two issues are addressed: First, why has growth been so strong in these particular clusters, i.e., can we identify the sources of the growth and dynamics in these sectors? Second, why do these two clusters differ in Ohio and Sweden in terms of size, level and type of activity, number and composition of actors, size structure of firms and growth patterns over the last couple of decades? In particular, what is the role of public policies as well as cultural, historical, and geographic factors? Our main conclusions are (1) that there is strong path dependence in both clusters in both countries, and (2) that the key to rapid development is a high absorptive capacity combined with rapid diffusion to new potential users. Our policy discussion addresses these issues.  相似文献

Knowledge, consumption, and endogenous growth   总被引:1,自引:1,他引:0  
In neoclassical theory, knowledge generates increasing returns – and therefore growth – because it is a public good that can be costlessly reused once created. In fact, however, much knowledge in the economy is actually tacit and not easily transmitted –and thus not an obvious source of increasing returns. Several writers have responded to this alarming circumstances by affirming hopefully that knowledge today is increasingly codified, general, and abstract – and increasingly less tacit. This paper disputes such a trend. But all is not lost: for knowledge does not have to be codified to be reused and therefore to generate economic growth.  相似文献

 This paper explains how and why the developed countries are undergoing a fundamental shift away from a managed economy and towards an entrepreneurial economy. This shift is shaping the development of western capitalism and has triggered a shift in government policies away from constraining the freedom of business to contract through regulation, public ownership and antitrust towards a new set of enabling policies which foster the creation and commercialization of new knowledge. The empirical evidence from a cross-section of countries over time suggests that those countries that have experienced a greater shift from the managed to the entrepreneurial economy have had lower levels of unemployment.  相似文献

Political entrepreneurship and bidding for political monopoly   总被引:2,自引:0,他引:2  
An analytical framework for dealing with political entrepreneurship and reform is proposed which is based on some new combinations of Schumpeterian political economy, an extended version of Tullock's model of democracy as franchise-bidding for natural monopoly and some basic elements of New Institutional Economics. It is shown that problems of insufficient award criteria and incomplete contracts which may arise in economic bidding schemes, also – and even more so – characterise political competition. At the same time, these conditions create leeway for Schumpeterian political entrepreneurship. The same is true for various barriers to entry in politics. These barriers affect a trade-off between political stability and political contestability which will be discussed with special emphasis on incentives and opportunities for political entrepreneurship in the sense of risking long-term investments in basic political reforms.  相似文献

To make intangibles more ‘tangible’ for empirical analysis, statistical cluster techniques are applied in the development of two new taxonomies of manufacturing industries. The first focuses on the distinction between exogenous, location dependent comparative cost advantages, such as the relative abundance of capital or labour, and endogenously created firm specific advantages resulting from intangible investments in marketing or innovation. The second taxonomy discriminates between industries according to their employment of skilled labour. Finally, econometric tests are used to investigate the presumed complementarity between intangible investments and human resources.  相似文献

In modeling expectation formation, economic agents are usually viewed as forming expectations adaptively or in accordance with some rationality postulate. We offer an alternative nonlinear model where agents exchange their opinions and information with each other. Such a model yields multiple equilibria, or attracting distributions, that are persistent but subject to sudden large jumps. Using German Federal Statistical Office economic indicators and German IFO Poll expectational data, we show that this kind of model performs well in simulation experiments. Focusing upon producers' expectations in the consumption goods sector, we also discover evidence that structural change in the interactive process occurred over the period of investigation (1970–1998). Specifically, interactions in expectation formation seem to have become less important over time.

This paper compares and contrasts the contributions of Joseph Alois Schumpeter and Josef Steindl to the competitive paradigm. Both reject the static nature of traditional profit maximizing analysis and the analytical device of a representative firm. Instead they both opt for a dynamic framework in which there is a key role for innovation. Differences emerge in terms of the characteristics of individual firms that nurture the competitive struggle and are responsible for technical change. The maturation process of a capitalist economy, whereby a natural progression will involve an increase in concentration, as prescribed by Schumpeter and Steindl is also explored, as is criticism of their analyses. Finally the holistic approach to competitive modelling, a legacy of these two economists, is expounded and challenges for the future identified.  相似文献

Starting from a discussion of Schumpeter's analysis of the relationships of capitalism, socialism and democracy, it is shown that, in a complex society, democracy is only compatible with a decentralized market economy with safe property rights. But in time democracy shows a tendency to weaken the capitalist system by more and more regulations and an ever-increasing share of government (including the social security system) in GDP. This tendency is a consequence of political competition because of the development of interest groups and the presence of rationally uninformed voters. It leads to a weakening of efficiency, investment, innovation and thus to lower growth rates of GDP. But in time forces opposing this development arise. First, because of the negative consequences of growing government the welfare and regulatory state is bound to move into a crisis in the long run. Thus innovative politicians have a chance to win the support of a majority of voters for reform projects, who perceive finally the ever-increasing burden of higher taxes and regulations and realize that these burdens are not worth the benefits bestowed on them. In doing so, they may face, however, the competition of ideologies. Second, there are other states with lower taxes and less unnecessary regulations which show higher growth rates of GDP, and gain thus relative advantages in international political and military competition since they can command greater resources with the passage of time. To maintain their relative international power position, reforms are thus considered as necessary by rulers. This may be helped by pressure resulting from comparisons of the standards of living done by their citizens.  相似文献

Formal rationality plays a limited role in human cognition, which originated in the creation of patterns to interpret phenomena and link phenomena with action. The creation of new patterns rests on imagination, not logic, typically stimulated by a perceived inadequacy in established patterns. Internal routines of the brain and external institutions form structures of cognitive capital; the institutions of markets, including money prices, aid the development of consumption capital, which simplifies most choices and provides scope for selective experiment and innovation in creating goods. Such innovation depends on differences between individuals and changes in their circumstances.  相似文献

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.  相似文献

Abstract. The system of denominations of US coins, which the paper treats as a quasi-genetic trait of the US monetary system, has not been constant since inception but rather has evolved over time in the sense of being subject to innovation and selection. However, all the innovations have disappeared, as have a number of the original denominations. Abstract theories of optimal systems of denominations provide a good explanation of one selection factor, but other important influences include limiting the number of separate denominations and accommodating the requirements of decimal counting. However, even some innovations that ultimately disappeared survived for decades.  相似文献

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.  相似文献
