Many countries have adopted labeling policies for genetically modified (GM) food, and the regulations vary considerably across countries. We evaluate the importance of political‐economic factors implicit in the choice of GM food labeling regulations. Using an analytical model, we show that production and trade‐related interests play a prominent role in labeling decision‐making. This conclusion is validated by an empirical analysis of GM food labeling policy choices. We find that countries producing GM crops are more likely to have less stringent labeling policies. Food and feed exporters to the European Union (EU) and Japan are more likely to have adopted stricter labeling policies. Labeling regulations in Asia and Europe are similar to those of Japan and the EU. Countries with no labeling policies are less developed, with important rural sectors and are more likely to have ratified the Cartagena Protocol on Biosafety. 相似文献

Abstract It is now commonplace to regard social norms as a subject of growing interest in the economic literature (e.g. game theoretical approaches based on ‘other‐regarding’ individual preferences, the analysis of the impact of rewards or punishment on individuals’ behaviour through experimental economics as well as field experiments, the revival of the institutionalist tradition spurred on by the influential work of Douglas North and followed by many others and the growing influence of neuroeconomics). In this paper, we focus on the relationship between incentives and social norms and survey the literature that could constitute the foundations of a motivation‐based economic analysis of social norms. Our main findings are that (1) the interaction between incentives and social norms is far from obvious since taking social norms into account involves the introduction of supplementary motives, in addition to self‐interest, into the economic analytical framework; (2) the analysis of the interaction between incentives and social norms resists an approach exclusively in terms of crowding‐in and ‐out effects because it is sensitive to whether it concerns behaviours driven by honour or by social stigma; (3) as a result, it is difficult to precisely evaluate the policy implication of the interactions between incentives and social norms. 相似文献

Assessing performance and value-creation capabilities in Lean healthcare: insights from a case study
ABSTRACTLean thinking is increasingly being applied worldwide. Yet its actual impact is still a puzzle, particularly when a ‘full-implementation approach’—which entails the adoption of a strategic approach to Lean dissemination on policy deployment procedures—is used. Focusing on the healthcare sector, this paper presents and tests a comprehensive measurement framework for Lean interventions. The paper explains how Lean testing can help decision-makers to solve managerial issues related to Lean initiatives. 相似文献

“中消协”把“健康·维权”列为2005年维权的主题,对于促进我国国民身心健康、落实以人为本的科学发展观和构建社会主义和谐社会,有很大的现实意义。“健康”是个大概念,包括身体健康、心理健康和人身安全等等,综合指标可以是国民的平均寿命影响健康和平均寿命的因素很多,诸如衣食住行、医疗保健、生活环境、人际关系等,既有外部的,相应的健康维权也需从多方面努力。从我国现实情况看,我以为应把食品的质量安全作为重点,因为:1 食品消费在国民健康和和构建和谐社会主义社会中具有特别重要的作用。民以食为天,食品消费是最基本的消费。… 相似文献

This paper investigates how various conjoint designs (full versus fractional) and estimation procedures (LINMAP, MONANOVA,
OLS) may interact with basic characteristics of the “true” utility functions (i.e., their range, shape, and curvature) when
estimating attribute importance weights. Substantial weight distortions are found, especially under a fractional design. 相似文献

Credit Constraints in Manufacturing Enterprises in Africa 总被引:2,自引:0,他引:2

We investigate the question of whether firms in Africa's manufacturingsector are credit constrained. The fact that few firms obtaincredit is not sufficient to prove constraints, since certainfirms may not have a demand for credit while others may be refusedcredit as part of profit maximising behaviour by banks. To investigatethis question, we use direct evidence on whether firms had ademand of credit and whether their demand was satisfied in theformal credit market, based on panel data on firms in the manufacturingsector from six African countries. Of those firms with a demandfor credit, only a quarter obtained a formal sector loan. Ouranalysis suggests that while banks allocate credit on the basisof expected profits, micro or small firms are much less likelyto get a loan than large firms. We also find that outstandingdebt is positively related with obtaining further lending. Therole of outstanding debt is likely to be a reflection of inefficiencyin credit markets, while the fact that size matters is consistentwith a bias as well, although we cannot totally exclude thatthey reflect transactions costs on the part of banks. We presentan analysis showing how much more profitable small firms mustbe to obtain a loan than large firms. 相似文献

Lattice schemes for option pricing, such as tree or grid/partial differential equation (p.d.e.) methods, are usually designed as a discrete version of an underlying continuous model of stock prices. The parameters of such schemes are chosen so that the discrete version “best” matches the continuous one. Only in the limit does the lattice option price model converge to the continuous one. Otherwise, a discretization bias remains. A simple modification of lattice schemes which reduces the discretization bias is proposed. The modification can, in theory, be applied to any lattice scheme. The main idea is to adjust the lattice parameters in such a way that the option price bias, not the stock price bias, is minimized. European options are used, for which the option price bias can be evaluated precisely, as a template to modify and improve American option methods. A numerical study is provided. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:733–757, 2006 相似文献
