The present round of multilateral trade negotiations is still deadlocked over agricultural trade. The European Union (EU) is urged by its trading partners to open its agricultural markets. Economic evaluations of trade liberalisation scenarios unanimously conclude that a substantial opening of agricultural markets is required for a successful (welfare‐improving) Doha Round. In this paper, we perform new evaluations to identify precisely the contributions of the European farm policy and to examine the robustness of these evaluations in the representation of this complex policy. Using the same specifications as in major previous studies, our first simulations show that the EU has a major responsibility in delivering significant gains to the developing countries. On the other hand, when we conduct the same experiments with a more relevant calibration and modelling of the European farm policy instruments, the gains that these developing countries may reap from the EU liberalisation are considerably reduced. Accordingly the current charge against the EU is simply inopportune. 相似文献

We discuss self-interested uses of equity arguments in international climate negotiations. Using unique data from a world-wide survey of agents involved in international climate policy, we show that the perceived support of different equity rules by regions may be explained by the ranking of their economic costs. Despite being self-interested, equity arguments may be perceived as being used for different reasons, for example, out of fairness considerations or in order to facilitate negotiations. Consistent with experimental and behavioral studies on fairness perceptions, we find that individuals are more likely to state reasons with positive attributes if they evaluate their own region or regions that support the individual's personally preferred equity rule. Negotiators perceive the use of equity by regions as less influenced by pressure from interest groups. 相似文献

Akut dekompensierte Herzinsuffizienz - Rund zwei Millionen Menschen in Deutschland
leiden an einer Herzinsuffizienz. Vor allem Dekompensationen des Krankheitsbildes
gef?hrden die Patienten und führen zu wiederholten Krankenhauseinweisungen. Ursache:
Oft falsche Medikamenteneinnahme oder die mangelnde Umsetzung von Verhaltensrestriktionen. Pflegekr?fte müssen bei ihrer Arbeit
daher verst?rkt auf Aspekte der Patientenedukation

A new class of asymmetric loss functions derived from the least absolute deviations or least squares loss with a constraint on the mean of one tail of the residual error distribution, is introduced for analyzing financial data. Motivated by risk management principles, the primary intent is to provide “cautious” forecasts under uncertainty. The net effect on fitted models is to shape the residuals so that on average only a prespecified proportion of predictions tend to fall above or below a desired threshold. The loss functions are reformulated as objective functions in the context of parameter estimation for linear regression models, and it is demonstrated how optimization can be implemented via linear programming. The method is a competitor of quantile regression, but is more flexible and broader in scope. An application is illustrated on prediction of NDX and SPX index returns data, while controlling the magnitude of a fraction of worst losses. 相似文献

This paper presents a model of the way ex-employees of an innovative, science-based entrepreneurial firm founded new enterprises based on copying the novel products of their former employer. The model focuses on the role played by the product-specific subculture of the innovative parent firm in the emergence of these imitative entrepreneurs. 相似文献

The purpose of the 1992 French Water Act is to encourage negotiation and dialogue among local stakeholders within a framework which is very similar to a patrimonial approach. Potential use of models in such post-normal approaches is analyzed. Two kinds of models are compared: one is agent-based, the other follows a more classical approach. They are compared according to their contributions as negotiation support tools. This comparison is based on a specific collective decision process dealing with water allocation at the sub-basin scale, in which authors are involved. Both are used to support collective decision processes through simulation of resource use dynamics. Agent-Based Models entail the broadening of spatial information of actors in the process, revealing inter-connected topics not taken into consideration earlier. This makes it possible to remain relevant, despite the sometimes rapidly evolving stakes. The central point of this paper is the implementation, within a practical application, of theories advocating the use of ABM as a collective decision support system. This application promotes a better understanding of the kind of support ABM provides and the way it does so. This is brought about more by re-framing the discussion and modifying the representation of the system on the part of the stakeholders than by providing specific agreements. 相似文献

This article reports the results of research to develop a survey instrument and its use to validate an ethical business culture construct (CEBC Model). The reported three-stage quantitative study builds on our previous qualitative work, aimed at identifying dimensions of ethical business cultures. The research resulted in a parsimonious construct, covering five dimensions of ethical business cultures, and a ten-question instrument, measuring this construct. In this article, we report results of exploratory and confirmatory factor analyses and convergent construct validity testing, discuss the potential applications of the construct and instrument in assessment and development of ethical business cultures, and provide recommendations for industry practitioners and for further research. 相似文献
