In theory, a poverty line can be defined as the cost of a common (inter‐personally comparable) utility level across a population. But how can one know if this holds in practice? For groups sharing common consumption needs but facing different prices, the theory of revealed preference can be used to derive testable implications of utility consistency knowing only the “poverty bundles” and their prices. Heterogeneity in needs calls for extra information. We argue that subjective welfare data offer a credible means of testing utility consistency across different needs groups. A case study of Russia's official poverty lines shows how revealed preference tests can be used in conjunction with qualitative information on needs heterogeneity. The results lead us to question the utility consistency of Russia's official poverty lines.  相似文献

How important are neighbourhood endowments of physical and human capital in explaining diverging fortunes over time for otherwise identical households in a developing rural economy? To answer this question we develop an estimable micro model of consumption growth allowing for constraints on factor mobility and externalities, whereby geographic capital can influence the productivity of a household's own capital. Our statistical test has considerable power in detecting geographic effects given that we control for latent heterogeneity in measured consumption growth rates at the micro level. We find robust evidence of geographic poverty traps in farm‐household panel data from post‐reform rural China. Our results strengthen the equity and efficiency case for public investment in lagging poor areas in this setting. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

How humor in advertising works: A meta-analytic test of alternative models   总被引:1,自引:0,他引:1  
This study tests a cognitive and an affective model based on extant explanations of the effects of humor along with a new affective?Ccognitive model. Results are derived from meta-analytic data and show how previous explanations may be integrated in order to explain how humor in advertising works. Humor reduces negative cognitions related to the ad because it serves as a distraction from counter-argumentation. In order to maintain positive affect, humor reduces cognitive efforts, in particular those related to brand-related cognitions, thus supporting a vampire effect; that is, humor distracts from processing central benefits of the brand. Humor exerts its strongest impact along affective paths, supporting the dominance of affective mechanisms. Affect and cognition do interplay in line with a congruency effect where the impact of positive affect on attitudes towards the ad is mediated by positive cognitions. The models differ when they are performed based on data from studies using either real or fictitious stimuli. Depending on the type of stimuli, slight changes occur that can be explained by the lack or existence of prior brand experience. Overall, the integration of affect and cognitions into one model provides a better explanation than the previous solely cognitive or solely affective models.  相似文献

The effects of portrayals of ethnic endorsers in advertising are ambiguous. These portrayals strengthen the ethnic identity of ethnic minority groups, thus leading to positive responses toward the ad. They can lead to negative responses, because these portrayals can be perceived as stereotyped. Humor is a tool that can increase positive effects of identity-building and reduce negative effects of stereotyping. In this study, we investigate how humor moderates the effects of ethnic advertising on consumers from ethnic minority and majority groups. We find that humor supports the effects of traditional portrayals for both groups. Moreover, the effect of traditional portrayals combined with humor is strongest for the minority group. These findings provide evidence for the positive effects of humor in ethnic advertising and thus provide new insights to the stereotyping, ethnic advertising, and humor literature. The findings have practical implications for advertising using ethnic endorsers, humor, or targeted at ethnic minority groups.  相似文献

Meta-analyses have become increasingly popular in many fields of the social sciences, including advertising research. The results of meta-analyses attract substantial interest from both scholars and practitioners, as indicated by high citation numbers and widespread dissemination in the media. By summarizing results drawn from a set of studies concerning a specific topic, and by discovering and explaining consistencies and inconsistencies within those results, meta-analysis is an essential step in the process of knowledge accumulation, theory building, and theory testing in science. Many developments in the last years have contributed to the advancement of the method, but they have appeared in disparate literatures. Furthermore, each discipline applies the method in a particular way that corresponds to the major research traditions in a field. However, no attempt to introduce the method to advertising researchers is available. The purpose of this article is therefore to provide a comprehensive overview of the meta-analysis method to advertising researchers that describes the procedures commonly applied in advertising research, that provides a better understanding of the method and evaluation criteria for judging the quality of meta-analyses, and that serves as a starting point for advertising researchers who are interested in conducting a meta-analysis.  相似文献

Socially responsible investing identifies the fiduciary duty and liability for financial advisors serving individual and institutional clients when consulting in the SRI space. This article first discusses the role of a fiduciary emerging from both a legal and an ethical basis. Further, the special aspects of maintaining fiduciary duty and minimizing fiduciary liability are described as they relate to SRI. A number of recommendations are discussed: legal, ethical, and practice. This study argues that prudence focuses more on the process of decisions rather than their outcomes, as measured exclusively by rate of return.  相似文献

Injuries account for a significant burden of mortality, morbidity, disability and health care costs. They differentially affect age and sex groups and reveal massive inequalities in occurrence within and between countries in Europe. Within countries, the poor suffer most and have least ability to change their exposures to risk. Addressing inequalities in injury occurrence would play a valuable role in reducing the differential burden of ill-health between rich and poor. Despite the evidence for many effective injury-related interventions, limited attention has been devoted to addressing injuries as a public health priority. This paper questions why attention has been limited to date and suggests policy action to support injuries being addressed as a mainstream concern by national and international health policy-makers. The paper briefly highlights the public health burden of injuries and violence; illustrates the range of inequalities that characterise their occurrence; highlights the scope for public health action and considers the extent to which policies that reduce the overall burden of injuries may also reduce inequalities in their occurrence; and finally examines why there has been a limited policy response to date and suggests ways of advancing the agenda.  相似文献

The purpose of this paper is to draw out and make explicit the assumptions made in the treatment of technology within business ethics. Drawing on the work of Freeman (1994, 2000) on the assumed separation between business and ethics, we propose a similar separation exists in the current analysis of technology and ethics. After first identifying and describing the separation thesis assumed in the analysis of technology, we will explore how this assumption manifests itself in the current literature. A different stream of analysis, that of science and technology studies (STS), provides a starting point in understanding the interconnectedness of technology and society. As we will demonstrate, business ethicists are uniquely positioned to analyze the relationship between business, technology, and society. The implications of a more complex and rich definition of ‘technology’ ripple through the analysis of business ethics. Finally, we propose a pragmatic approach to understanding technology and explore the implications of such an approach to technology. This new approach captures the broader understanding of technology advocated by those in STS and allows business ethicists to analyze a broader array of dilemmas and decisions.  相似文献

Policymakers, consumer advocate groups, and researchers agree that consumers need to increase their proenvironmental behaviors if a decent standard of living is to be ensured for future generations. Despite high levels of environmental concern, consumers still refrain from large‐scale adoption of proenvironmental behaviors. Social marketers agree that a change in attitudes is not enough to stimulate the necessary behavioral change and are looking for ways to help consumers overcome the costs (e.g., price premiums, inconvenience) that are often associated with proenvironmental behaviors. Currently, consumers often see proenvironmental behavior as a trade‐off between short‐term personal benefits and longer term collective benefits. The authors contribute to the social marketing literature on proenvironmental behavior by introducing the concept of Consumer Environmental Stewardship (CENS), which centers on the use of intrinsic motivation to stimulate a personal sense of responsibility for the environment. The findings, based on a survey and three experiments, show that the stimulation of consumers’ affinity with future generations (AFGs) and perceived consumer effectiveness (PCE) can help to promote CENS, which in turn raises proenvironmental behaviors. However, this research also shows that increasing levels of AFGs can backfire and result in lower levels of CENS, if consumers experience low levels of PCE.  相似文献
