从“大萧条”看中美两国应对当前金融危机之策 总被引:2,自引:0,他引:2
本文站在历史的角度,审视与检讨中关两国政府在应对当前由次贷风暴引发的金融危机中的得与失。历史是一面镜子,发生在20世纪30年代的世界性大萧条与今日美国金融危机在很多方面具有相似之处。以史为鉴,在百年一遇的危机面前,各国政府应携手并进,同舟共济,避免陷入更深的困境。当前的局势为中国充分展示负责任大国的形象提供了契机。 相似文献

Hypothesis tests using data envelopment analysis 总被引:5,自引:4,他引:1
Rajiv D. Banker 《Journal of Productivity Analysis》1996,7(2-3):139-159
A substantial body of recent work has opened the way to exploring the statistical properties of DEA estimators of production frontiers and related efficiency measures. The purpose of this paper is to survey several possibilities that have been pursued, and to present them in a unified framework. These include the development of statistics to test hypotheses about the characteristics of the production frontier, such as returns to scale, input substitutability, and model specification, and also about variation in efficiencies relative to the production frontier. 相似文献

Many regions have experienced long-run economic fluctuations generated by the life cycles of their dominant industrial clusters. During the downswings in the 1970s and 1980s, proactive structural policies were typically launched in German regions to combat job losses in their core clusters and to create new jobs in new industries. With respect to the German State of Bremen, this paper provides empirical evidence of: (1) a long-run regional downswing; (2) the potential job effects of proactive regional industrial policy programmes in terms of increasing regional employment, by safeguarding jobs in the regional core industries and creating new jobs in new growth industries; and (3) a time pattern in the job effects, which are related to the different generations of programmes. 相似文献

The economic impact of adopting herd health programs for mastitis and reproduction by small-scale dairy producers of Central Thailand was assessed using a policy analysis matrix (PAM). Following a reduction in the incidence of bovine disease on adopter farms, an increase in private net profits is observed. More importantly the social costs of supporting dairy farmers is reduced; the PAM effective protection coefficient was reduced by 35% for mastitis program adopters and by 44% for reproductive program adopters, indicating improved social efficiency of dairy policy. Other indicators of efficiency and policy implications are discussed. 相似文献

Between 1974 and 1988, executives of DuPont, the world's largest producer of CFCs, were confronted with emerging evidence that CFCs were destroying the stratospheric ozone layer. The difficulty that executives face in such cases is that scientific knowledge develops over time and does not necessarily proceed in a straight line toward true conclusions. At the beginning of a new field of research, there is much uncertainty and disagreement among the experts. The solution of the ozone problem required a remarkable cooperation among science, business, and international governments. After looking at the role of DuPont executives in this drama, and the difficulties facing any executive dealing with uncertain science, the paper turns to an evaluation of the field of Business Ethics to see what light it might throw on this and analogous problems. Finally, the paper offers specific suggestions in terms of principles in dealing with uncertain science, and concludes that the course of action that DuPont followed, including some mistakes, can serve as a model for analogous crises. 相似文献

Planning food services for a campus setting 总被引:1,自引:0,他引:1
Kenneth J. Klassen Elzbieta Trybus Arundhati Kumar 《International Journal of Hospitality Management》2005,24(4):579-609
Providing appropriate food services in a campus setting is increasingly important due to more demanding customers and because clients have less time to go off-campus when they need to eat. Using a university campus as an example, this research looks at customer satisfaction with existing food services and explores various methods for determining where to locate new facilities. This campus currently has great needs for additional food services, and it is shown clearly where additional food services are required. Also, the methods used are compared in terms of their effectiveness in finding the solution. 相似文献

养老保险金替代率研究 总被引:2,自引:1,他引:1
褚福灵 《北京劳动保障职业学院学报》2004,12(3):17-21
养老保险金替代率是指一定地区当年离退休(含退职,下同)人员的养老金平均水平与该地区当年职工平均工资水平的比率,其是否合理,将影响到养老保险制度安排和政策取向。养老保险金替代率目标的确定,将受到一个国家或者地区的社会保障水平和经济发展水平等因素的影响。按照中国对基本养老保险制度改革的总体思路,未来基本养老保险金替代率目标确定为60%左右。目前,中国基本养老保险金替代率目标已经接近制度改革的目标,北京市的基本养老保险金替代率明显低于全国水平。企业退休金的替代率又明显低于事业和机关单位的退休金替代率,并呈现持续下降的趋势,应当设法进行遏止。 相似文献

The present research provides a justification for the popularity of the technical analysis. It finds that financial analysts firmly discriminate between two types of technical signals—those based on typical cognitive biases and “empty” signals that sound like a technical analysis but are without any connotation with psychological inclinations.At the same time that they treat them differently, different analysts rate these items very similarly. These results suggest that the popularity of technical analysis is associated with its relation to the typical cognitive biases of humans. 相似文献
