Abstract Introduction. Les méthodes de calcul de la prime de réassurance Excess-Loss utilisées jusqu'à présent ou bien avaient un caractère purement empirique, ou bien présumaient que les écarts entre le montant des sinistres constatés et le montant des sinistres attendus se répartissent suivant la loi de Laplace-Gauss. 相似文献

Relations between non-governmental organizations (NGOs) and companies have been the subject of a sharply increasing amount of publications in recent years within academic business journals. In this article, we critically assess this fast-developing body of literature, which we treat as forming a ‘business and society discourse’ on NGO–business relations. Drawing on discourse theory, we examine 199 academic articles in 11 business and society, international business, and management journals. Focusing on the dominant articulations on the NGO–business relationship and key signifiers they rely on, we analyze the problem-settings of articles in order to reveal the statements that are acceptable and appropriate within this field. Our threefold aim is to (1) identify dominant articulations of NGO–business relations in business and society discourse, (2) expose those articulations that are silenced or suppressed by these dominant articulations, and (3) critically assess possible power effects of these discursive dynamics in the field of discursivity. While business and society discourse on NGO–business relations overall remains open to many different articulations, we also find that those articulations that focus on NGO–business partnerships and governance initiatives tend to privilege collaborative and deliberative ways of engaging and marginalize more adversarial subject positions. We call for more recognition of the potentially constructive role that can be played by conflict. 相似文献

This article presents an open discussion of the processes of urban secession and gentrification in contemporary European cities, arguing that intergroup social dynamics in urban spaces are generally more complex than either extreme mutual avoidance or the colonization of neighbourhoods by the wealthiest groups. We analyse the residential strategies of urban upper‐middle class managers in various European metropolitan areas through in‐depth semi‐structured interviews to argue that these groups develop complex strategies of proximity and distance in relation to other social groups. The development of these ‘partial exit’ strategies takes place through specific combinations of practices that allow groups to select the dimensions they are willing to share with other social groups, and those in which they prefer a more segregated social environment for themselves and their families. The responses of our interviewees were consistently more nuanced and complex than suggested by a simplistic theory about their drive to withdraw from society, forcing us to develop more sophisticated conceptual frameworks to account for the growing prevalence of multi‐layered identities and spheres of reference and solidarity, specific combinations of elective segregation and local involvement, and more active patterns of mobility combined with local embeddedness. 相似文献

The paper proposes in a regime-shift framework, an arbitrage-free term structure model based on the target and Fed Funds Rates. Empirical observations suggest that a three-state regime-shift environment associated with FOMC monetary actions is justified. Then, a closed-form solution for zero-coupon bonds is derived where regime-shift risk is priced. The solution is flexible enough to incorporate additional state variables. 相似文献

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
