Collaborative, team-based research is now the most significant mode of activity in the global scientific community. Anecdotal and statistical evidence shows moreover that collaboration in scientific research is increasingly global in nature. That is, the groups of researchers who are involved in scientific progress often span one or more nations in origin, location and/or sponsorship. Another significant trend in recent cases of scientific collaboration is the increase in cross-sectoral cooperation, where researchers in a group are employed by government, private industry, and/or academic and other non-profit institutions.
In this paper, we review the scale, scope and intensity of cross-national, cross-sectoral research collaboration through the analysis of historical data on co-authorship of scientific publications. The first part of the paper reviews existing literature on the analysis of co-authorship data, and discusses the limitations of this form of analysis and typical strategies to mitigate those limitations. The second part of the paper describes a preliminary study of cross-national, cross-sectoral scientific collaborations covering the years 1988 through 1997, where we examined the scale (volume of co-authored papers), intensity (co-authored papers versus other kinds of co-authorship), and scope (patterns in co-authorship) for cross-national, cross-sectoral collaborations. The conclusion of the paper discusses significant trends and patterns derived from this study, and their implications for further research into these types of collaborations.  相似文献

This article presents evidence that the European Monetary System (EMS) bands for the Italian lira and the pound sterling were not credible for most of the period 1990–1992, and especially during the week prior to their withdrawal from the EMS system. Using a simple test, developed by Svensson, domestic interest rates for both Italy and the United Kingdom have been found to be mostly outside the rate-of-return bands implied by the official arrangements of the EMS target zone system. Furthermore, comparing implied forward rates for various maturities with the official EMS bands of both currencies, we again found that the followed monetary policies in both countries were not in general consistent with those needed to maintain an orderly functioning of the (EMS) system. The Svensson test can further be used as an indicator of potential speculative attacks on an EMS currency, and, in turn, as a signal of an emerging need to adjust the corresponding country's monetary policy.  相似文献

Etzioni versus Becker: Do Moral Sentiments differ from Ordinary Tastes?   总被引:1,自引:1,他引:0  
Elias L. Khalil 《De Economist》1997,145(4):491-520
There are two competing definitions of economics. One, exemplified in Etzioni's work, stipulates that economics is the study of one kind of ends, the pursuit of material benefits (welfare). This definition entails that material ends are incommensurable with moral ends. The other, expressed in Becker's work, registers that economics is the analysis of one aspect of all ends, optimization. This definition implies that material and moral ends are commensurable. The paper finds that each definition has its own shortcomings. The paper outlines an alternative view, illustrated by the difference between gifts and grants, which promises to supplant the shortcomings of each definition.  相似文献

The recent market turmoil has brought attention to how deregulation of the financial sector may affect risk. The purpose of our study is to examine the market's perception of risk associated with deregulation. We accomplish this by decomposing security risk around deregulation into systematic and unsystematic risk. We examine deregulation of several industries and find a consistent pattern of risk adjustment to deregulation, whereby the increase in security risk is temporary and largely unsystematic.  相似文献

Suppose an investor has a fixed decision horizon and an appropriate utility function for measuring his or her utility of wealth. If there are only two investment vehicles, a risky and a risk-free asset, then the optimal investment strategy is such that, at any time, the amount invested in the risky asset must be the product of his or her “current risk tolerance” and the risk premium on the risky asset, divided by the square of the diffusion coefficient of the risky asset. In the case of more than one risky asset, the optimal investment strategy is similar, with the ratios of the amounts invested in the different risky assets being constant over time.  相似文献

Friedrich Hayek's Theory of Spontaneous Order: Two Problems   总被引:1,自引:0,他引:1  
The paper finds Hayek's basic building block, the natural/artificialcontrast, to be illuminating. But the manner in which Hayek classifiesentities according to the contrast generates two major problemsin his socio-economic theory. First, Hayek's concept designconfuses the technical construction of, e.g., a chair with thedeliberate organization of division of labor within the firm.Second, Hayek's notion spontaneous order fails to note twokinds of natural order — firms and markets.  相似文献

Trade policy barriers and high transaction costs hinder developing countries from taking the full advantages of the global trading system. In order to help developing countries overcome the problem, the World Trade Organization (WTO) launched the Aid for Trade (AFT) initiatives in its Ministerial Conference held in Hong Kong in 2005. We examine the effects of AFT inflows on bilateral trade costs facing 133 developing countries while accounting for differences in their location on the contours of various measures of institutional quality. Our results from the estimation of a mixed effects (random-intercept and random-coefficient) model indicate that institutional quality significantly affects the extent to which AFT reduces bilateral trade costs. An important policy implication of our findings is that an economically robust and sustainable reduction in bilateral trade costs facing developing countries requires the presence of both promulgated and effectively functioning institutions such as regulatory power and the rule of law.  相似文献

The paper argues that the application of nonlinear dynamics borrowed from thermodynamics for the study of the evolution of institutions amounts to an identificational slip. While the paper welcomes the importation of techniques from the natural sciences, thermodynamic feedback is simply an inappropriate technique for the study of evolutionary change. Thermodynamic feedback is only appropriate for the study of social dynamics like mob behavior, stock market gyrations, and fad cycles. One should rather appeal to the evolution of species-as recorded by change of gene frequency and phenotypic traits—as the appropriate metaphor for the study of evolution of culture—as manifested by change of rules and principles and their consequent order.  相似文献
