Recent work by Y. Kannai and B. Peleg shows that two appealing axioms for extending a linear order on a set of six or more elements to a weak order on the family of non-empty subsets of that set are mutually incompatible. This comment shows that a modest restriction of their monotonicity axiom is compatible for extension with a generalization of their other axiom provided that the linear order on the basic set is a well ordering. 相似文献

The paper develops a North–Middle–South model to formulate a middle economy that plays catch-up via imitative R&D to acquire newer technologies from a higher-wage innovative forerunner, while playing “reverse catch-up” via outbound FDI to transfer older technologies to a lower-wage follower. A critical policy dilemma facing the middle economy is how to balance its R&D-driven technology inflows against its FDI-driven technology outflows. Numerical simulations are used for dynamic welfare analysis. This paper finds that tightening FDI permits the middle economy to keep a lower saving rate without weakening its ability to acquire newer technologies in the long run. 相似文献

This paper analyses the potential welfare gains of introducing a technology transfer from Annex I to non-Annex I in order to mitigate greenhouse gas emissions. Our analysis is based on a numerical general equilibrium model for a world-economy comprising two regions; North (Annex I) and South (non-Annex I). In a cooperative equilibrium, a technology transfer from the North to the South is clearly desirable from the perspective of a ‘global social planner’, since the welfare gain for the South outweighs the welfare loss for the North. However, if the regions do not cooperate, then the incentives to introduce the technology transfer appear to be relatively weak from the perspective of the North; at least if we allow for Southern abatement in the pre-transfer Nash equilibrium. Finally, by adding the emission reductions associated with the Kyoto agreement, our results show that the technology transfer leads to higher welfare in both regions. 相似文献

Objective: Epilepsy surgery is one of the most effective treatments in modern medicine. Yet, it remains largely under-utilized, in spite of its proven efficacy. The referrals for epilepsy surgery are often delayed until it is too late to prevent the detrimental psychosocial effects of refractory seizures. The reluctance towards epilepsy surgery is influenced by the perceived risks of the procedure by practitioners and patients. This review discusses how, in general decision-making processes, one faces a natural tendency towards emphasizing the risks of the most immediate and operational decision (surgery), at times without contrasting these risks with the alternative (uncontrolled epilepsy).Methods: In the field of economics, this bias is well recognized and can be overcome through marginal analysis, formally defined as focusing on incremental changes as opposed to absolute levels.Results: Regarding epilepsy surgery, the risks and benefits of surgery are considered separately from the risks of uncontrolled epilepsy. For instance, even though surgery carries an ~0.1–0.5% risk of perioperative mortality, the chance of sudden unexpected death with refractory epilepsy can be as high as 0.6–0.9% per year. It is suggested that the inadequate way of phrasing clinical questions can be a crucial contributing factor for the under-utilization of epilepsy surgery.Significance: It is proposed that examining decision-making for epilepsy surgery in the context of marginal analysis may enable providers and patients to make more accurate informed decisions. 相似文献

Identifying the value orientations of subjects participating in market or non-market decisions by having them participate in a ring game may be helpful in understanding the behaviour of these subjects. This experiment presents the results of changes in the centre and the radius of a value orientations ring in an attempt to discover if the measured value orientations exhibit income or displacement effects. Neither significant income effects nor displacement effects are identified. An external validity check with a voluntary contribution game provides evidence that value orientations from rings centred around the origin of the decision-space explain significant portions of voluntary contributions while value orientations from displaced rings do not. 相似文献

The article analyzes the welfare cost of the U.S. sugar program using a multimarket model of U.S. sweetener markets. The latter includes raw crops, sugar extraction and refining, and sweetener users (food-processing industries and final consumers). The authors address the industrial organization of food industries using sweeteners and treat the United States as a large importer. With the removal of the program, this article estimates (all figures in 1999 dollars) that in 1998 cane growers, sugar beet growers, and processors would have lost $307, $650, and $89 million, respectively; sweetener users would have gained $1.9 billion. World prices would have increased by 13.2%. The deadweight loss of the program is estimated at $532 million. 相似文献

The Canada Foundation for Innovation (CFI) and the Canadian Institutes of Health Research (CIHR) allied to analyze the impact of their investments in medical imaging research. The CFI funds capital and operating programs for research infrastructure, and CIHR's mandate concentrates its funding on research activity. It happens that CIHR-funded research consumes CFI-funded infrastructure as an input in the innovation process. Apart from a few partnered programs, by design there is no coordination between CFI and CIHR funding decisions. Together, these agencies invested $916 million over a 14-year-period. In this paper, we evaluate the economic and health benefits from advancements in one funded area, namely computed tomography perfusion (CTP). CTP is an imaging technique that uses computed tomography to measure blood flow in organs and tissues. It is mostly used to assess acute ischemic stroke. The net social benefits attributable to these investments are substantially positive: the benefit-to-cost ratio is estimated to be between 6.66-to-1 and 9.99-to-1. We review how public investments from multiple funders comingle in the innovation process to deliver social value and improved health outcomes. 相似文献
