We study uncertainty averse preferences, that is, complete and transitive preferences that are convex and monotone. We establish a representation result, which is at the same time general and rich in structure. Many objective functions commonly used in applications are special cases of this representation. 相似文献

After the upheavals in Central and Eastern Europe in the late 1980s and early 1990s, the Western world has given considerable aid to the fledgling democracies. In this paper we draw a summary from Baltic experience in the fields of educational programs, scientific and environmental programs, and commercial projects in banking, taxation, and energy. We analyze the motivation and identify different possible effects of foreign aid. We signal possible inefficiencies arising from the lack of coordination of foreign aid, deal with possible waste as being a form of loss in cost-effectiveness, and address the policies followed by aid-providing agencies. Finally, we suggest ways that can help to achieve cost-effectiveness by assisting the donor and recipient in maximizing benefits gained and possibly reducing costs. 相似文献

Summary. In this paper, I study the existence of Sunspot Equilibria in a general framework whose dynamics allow for the presence of
predetermined variables in the system. The main motivation for this research comes from the fact that previous studies did
not allow for such predetermined variables which, nevertheless, appear quite naturally in economic models. I show, for a non-negligible
subset of dynamics with predetermined variables verifying usual assumptions, the existence of Stationary Sunspot Equilibria
fluctuating between an arbitrary finite number of states arbitrarily close to a steady state.

Friedrich Hayek's Theory of Spontaneous Order: Two Problems 总被引:1,自引:0,他引:1
Elias L. Khalil 《Constitutional Political Economy》1997,8(4):301-317
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

Managed care has demonstrated its ability to contain costs. Its emergence as a dominant factor in the health care marketplace has raised concerns about measuring health care quality. As the field of quality assurance is evolving, it is becoming clearer that patient satisfaction surveys should be an integral component of assessing care. 相似文献

Scenario analysis is an approach to long-term planning that informs decision-making in contexts of highly uncertain future conditions. Scenario-based studies are rapidly growing in popularity, yet many aspects of the method are not fully understood. Participants' willingness to suspend disbelief in possible futures is an integral component of scenario-based studies, essential for considering alternative future scenarios, yet little is known about the factors that affect it. Participation in a scenario project does not necessarily imply willingness or ability to suspend disbelief; participants may not suspend disbelief simply upon request. However, the scenario literature says little about the aspects of scenario-based studies that influence suspension of disbelief.This article explores the factors that influenced the suspension of disbelief in one scenario exercise about the future of Canada's forests. Participants differed in their abilities to suspend disbelief in the scenarios in part because of their past experiences and expertise in particular areas, and their assessments of probable and desired future outcomes. Elements of the project design and implementation influenced participants' abilities to engage the scenarios. The results have implications for those interested in using scenarios for helping people and communities envision possible - and sustainable - futures. 相似文献

Food consumption causes, together with mobility, shelter and the use of electrical products, most life cycle impacts of consumption. Meat and dairy are among the highest contributors to environmental impacts from food consumption. A healthier diet might have less environmental impacts. Using the E3IOT environmentally extended input output database developed in an EU study on Environmental Impacts of Products (EIPRO), this paper estimates the difference in impacts between the European status quo and three simulated diet baskets, i.e. a pattern according to universal dietary recommendations, the same pattern with reduced meat consumption, and a ‘Mediterranean’ pattern with reduced meat consumption. Production technologies, protein and energy intake were kept constant. Though this implies just moderate dietary shifts, impact reductions of up to 8% were possible in reduced meat scenarios. The slightly changed food costs do not lead to significant first order rebound effects. Second order rebounds were estimated by applying the CAPRI partial equilibrium model. This analysis showed that European meat production sector will most likely respond by higher exports to compensate for losses on the domestic meat market. Higher impact reductions probably would need more drastic diet changes. 相似文献
