We survey the methodological advances in DEA over the last 25 years and discuss the necessary conditions for a sound empirical application. We hope this survey will contribute to the further dissemination of DEA, the knowledge of its relative strengths and weaknesses, and the tools currently available for exploiting its full potential. Our main points are illustrated by the case of the DEA study used by the regulatory office of the Dutch electricity sector (Dienst Toezicht Elektriciteitswet; Dte) for setting price caps. 相似文献

This article reports on the symposium on the ‘Social Mastery of Technology’ (MASTECH) organized by the CNRS Industrial Economics Research Group and the Maison Rhône-Alpes des Sciences de l'Homme in Lyon, France, 9–12 September 1991, under the patronage of UNESCO, which was a major innovation among scientific communities in the area of human sciences. 相似文献

Markets reacted strongly to the World Trade Center attacks both in Europe and in the United States. The extent of this crisis was difficult to assess at the time, underlining the need for a specific tool to measure the magnitude of financial crises. A first measure was recently proposed and applied to the foreign exchange market by Zumbach et al. (2000a,b ). Their measure relies on an analogy with geophysics; the related index of market shocks (IMS) that we propose here is also the counterpart of the Richter scale used for earthquakes. We apply this measure on the French and the American stock markets to put large market events into perspective. The crisis triggered by the September attacks was actually the worst since 1987, and the ninth worst when compared to major historical ones. 相似文献

This study examines the magnitude and determinants of the establishment-size wage premium in five European countries using a unique harmonised matched employer–employee data set (the 1995 European Structure of Earnings Survey). This data set enables to test the validity of various traditional explanations of the size wage gap (i.e. the labour quality hypothesis, the theory of compensating wage differentials, the role of monitoring and institutions) and of more recent hypotheses (i.e. size differences in job stability and in the concentration of skilled workers). We find some support for traditional explanations, but there remains a significant wage premium for workers employed in large establishments. Further results indicate that the magnitude of this premium fluctuates substantially across countries and appears to be negatively correlated with the degree of corporatism. 相似文献

This paper studies the relationship between bilateral trade patterns and opinions. It uses the Eurobarometer public opinion surveys published by the European Commission, which provide data on the share of the population in each EU15 member country in favour of each CEEC joining the EU. Our results first suggest that bilateral opinions have a statistically robust and relatively large effect on imports, even when standard and new covariates capturing proximity between countries are controlled for. We interpret this effect as reflecting a positive impact of “bilateral affinity” on trade patterns. We also show that it is possible to go some way towards explaining the variance in bilateral opinions among our sample. Last we provide some preliminary attempt to determine causality between bilateral opinions and imports. 相似文献

Peers' valuation matters for firms' investment: a one standard deviation increase in peers' valuation is associated with a 5.9% increase in corporate investment. This association is stronger when a firm's stock price informativeness is lower or when its managers appear less informed. Also, the sensitivity of a firm's investment to its stock price is lower when its peers' stock price informativeness is higher or when demands for its products and its peers' products are more correlated. Furthermore, the sensitivity of firms' investment to their peers' valuation drops significantly after going public. These findings are uniquely predicted by a model in which managers learn information from their peers' valuation. 相似文献

This article examines unconventional entrepreneurship (accidental or end‐user entrepreneurs) to determine whether the decision‐making phase of the entrepreneurial process is collective. The analysis identified a virtuous circle that links knowledge, innovation, judgment, and decision making to collective interactions built on passion, experience, and sharing. To study food bloggers as unconventional user entrepreneurs, data were collected and analyzed using netnographic analysis. A supplementary online survey of food bloggers and their followers was also performed. Three groups of food bloggers are identified: amusing, functional, and fervent. Only fervent food bloggers, thanks to the virtuous circle built on passion, experience, and sharing as enablers, can be considered accidental or end‐user entrepreneurs. 相似文献

Scientific collaboration is a complex phenomenon that improves the sharing of competences and the production of new scientific
knowledge. Social Network Analysis is often used to describe the scientific collaboration patterns defined by co-authorship
relationships. Different phases of the analysis of collaboration are related to: data collection, network boundary setting,
relational data matrix definition, data analysis and interpretation of results. The aim of this paper is to point out some
issues that arise in these different phases, highlighting: (i) the use of local archives versus international bibliographic
databases; (ii) the use of different approaches for setting boundaries in a whole-network; (iii) the definition of a co-authorship
data matrix (binary and weighted ties) and (iv) the analysis and the interpretation of network measures for co-authorship
data. We discuss the different choices that can be made in these phases within an illustrative example on real data which
is referred to scientific collaboration among researchers affiliated to an academic institution. In particular, we compare
global and actor-level network measures computed from binary and weighted co-authorship networks in different disciplines. 相似文献

This study examines the influence of perceived risk on entrepreneurial desirability and feasibility as determining factors in the intention to start a self-owned business. Specifically, a multidimensional approach is taken to examine the different types of risks associated with entrepreneurship: economic, social, time, health and personal risks. The results obtained from a sample of 376 new entrepreneurs in Mexico confirm the fact that the perceived desirability and feasibility have a significant and positive effect on the intentions to start their own company. On one hand, the empirical evidence obtained shows a heterogenic effect of the risk dimensions associated with entrepreneurship on the perceived desirability and feasibility in their behaviour. Therefore, it was found that the economic risk associated with entrepreneurship has a negative effect on the feasibility to start a business, but does not significantly influence the desirability of that behaviour. On the other hand, a significant effect from the risk related to health is not seen on desirability and feasibility, but the negative influence of personal risk is empirically supported for both variables. Finally, the results obtained related to social and time risk are contradictory. Social risk negatively influences entrepreneurship desirability, but a positive effect is observed on the feasibility to create a business. For its part, the empirical evidence obtained does not support any effect of the time risk on the perceived feasibility of starting a business, but there is a positive on entrepreneurship desirability. These results, which are contrary to the traditional concept of risk as a barrier to entrepreneurship, are justified by the vocational nature of this behaviour and by the social sacrifices that are sometimes necessary to be able to make a business work. 相似文献
