The Ethical Mutual Fund Performance Debate: New Evidence from Canada   总被引:1,自引:0,他引:1  
Although the academic interest in ethical mutual fund performance has developed steadily, the evidence to date is mainly sample-specific. To tackle this critique, new research should extend to unexplored countries. Using this as a motivation, we examine the performance and risk sensitivities of Canadian ethical mutual funds vis-à-vis their conventional peers. In order to overcome the methodological deficiencies most prior papers suffered from, we use performance measurement approaches in the spirit of Carhart (1997, Journal of Finance 52(1): 57–82) and Ferson and Schadt (1996, Journal of Finance 51(2): 425–461). In doing so, we investigate the aggregated performance and investment style of ethical and conventional mutual funds and allow for time variation in the funds’ systematic risk. Our␣Canadian evidence supports the conjecture that any␣performance differential between ethical mutual funds and their conventional peers is statistically insignificant.   相似文献

Corporate Social Responsibility (CSR) programs are increasingly popular corporate marketing strategies. This paper argues that CSR programs can fall along a continuum between two endpoints: Institutionalized programs and Promotional programs. This classification is based on an exploratory study examining the variance of four responses from the consumer stakeholder group toward these two categories of CSR. Institutionalized CSR programs are argued to be most effective at increasing customer loyalty, enhancing attitude toward the company, and decreasing consumer skepticism. Promotional CSR programs are argued to be more effective at generating purchase intent. Ethical and managerial implications of these preliminary findings are discussed.

She researches in the areas of cause-related marketing, corporate social responsibility, and new product development. Shruti Gupta, Ph.D., is an Assistant Professor of Management at The Pennsylvania State University at Abington, in Abington, Pennsylvania. Dr. Gupta’s research interests lie in the area of corporate social responsibility, cause-related marketing, environmental consumerism, and social marketing issues.

This paper reports on the development of a research instrument designed to explore ethical reasoning in a tax context. This research instrument is a version of the Defining Issues Test (DIT) originally developed by Rest [1979a, Development in Judging Moral Issues (University of Minnesota Press, Minneapolis, MN); 1979b, Defining Issues Test (University of Minnesota Press, Minneapolis, MN)], but adapted to focus specifically on the environment encountered by tax practitioners. The paper explores reasons for developing a context- (and profession-) specific test, and details the manner in which this was undertaken. The study on which it is based aims to compare the reasoning of tax practitioners in the tax-specific context and in the general social context covered by the original DIT, and to compare this with the reasoning of non-specialists in these two contexts. The paper therefore also considers the issues that arise when using such tests to compare reasoning in different domains or to compare groups. The focus on instrument development to measure ethical reasoning in a specific domain will contribute to the literature on research methods in the area of the DIT and will facilitate cross-study comparisons.  相似文献

Herausforderndes Verhalten bei Demenz - Wenn Aggression, erh?hter Bewegungsdrang, starke Orientierungsprobleme, Selbst- und Fremdgef?hrdung oder andere „herausfordernde“ Verhaltensweisen auftreten, wird die Pflege und Begleitung von Demenzkranken als Belastung erlebt. Doch Pflegende stehen dem Problem nicht hilflos gegenüber. Eine interdisziplin?re Expertengruppe gibt mit ihren Empfehlungen ein Handlungsgerüst.  相似文献

The rise in ethical and social responsibility awareness in contemporary businesses has led to assumptions that the associated behaviours would enable competitive advantage to be attained as a firm distinguishes itself from its competitors through such practices. This paper reports on a study conducted on the prevalence of such practices among entrepreneurial ventures in an emerging economy (Malaysia), and the effect of such practices on both financial and non-financial performance. A sequential inter-method mixing design was employed in which during stage 1, a series of semi-structured interviews with ten Malaysian SME founder-owners were conducted. Stage 2 involved a survey in which a total of 212 usable questionnaires were received. The results of the first phase of the research (qualitative) found evidence that entrepreneurial ventures in Malaysia do generally engage in both ethical and socially responsible practices. The subsequent model testing using SEM, however, revealed that while ethical practices were positively associated with venture performance, socially responsible practices were not. This may indicate that while entrepreneurial ventures in emerging economies like Malaysia become quickly aware of the more serious consequences of not adopting ethical practices, the concern for social issues may still be lacking, i.e., in terms of motivations, they may be closer to the profitable end of the philanthropy versus profitability spectrum. While the findings may be equivocal, we believe that the paper makes the following two significant contributions: (1) it provides an empirical test of the importance of ethical and socially responsible practices to entrepreneurial venture performance and (2) it furthers understanding of how and why this may be different in an emerging economy context.  相似文献

The pattern of international trade is changing constantly. The HWWA Index of World Market Prices of Commodities, which is weighted by imports, therefore needs to be adapted from time to time in order to preserve its relevance as an indicator of price trends in international commodity markets. It is now (as of September 2003) published with updated weights based on 1999–2001 import values and with a new price basis (2000=100).  相似文献

Opening the black box: Finding the source of cost inefficiency   总被引:2,自引:0,他引:2  
Parametric and nonparametric procedures are used to identify the apparent source of cost inefficiency in banking. Inefficiencies of 20–25% from earlier studies are reduced to 1–5% when, in addition to commonly specified cost function influences, variables reflecting banks’ external business environment and industry indicators of “productivity” are added. These productivity indicators explain most of the reduction in bank operating cost over 1992–2001 and was 5 times the reduction in the dispersion of inefficiency. Inefficiency appears stable over time because it is small relative to industry-wide cost changes occurring concurrently and because technology dispersion is imperfect.

This paper focuses on the sources of intra‐industry price variability in US food industries during a period of increasing concentration, while accounting for the impact of variations in prices of primary agricultural products. Results suggest that intra‐industry price variability in food industries increases with their respective mean rate of inflation and product heterogeneity. However, industrial concentration lowers the sensitivity of relative prices to changes in the mean rate of inflation. Hence, static welfare losses to consumers from increasing concentration in food industries, a subject of recent and intensive investigation, can partly be offset by gains such as reduced price variability.  相似文献

This article uses migrant workers' testimonies to analyse whether and how much the act of migrating seasonally for wage work has contributed to changing social relations. We investigate changes in the meaning of this kind of migration to workers involved in it over their working lives. The emergence of peasant capitalism in West Bengal from the 1970s resulted in more days work and higher wages for migrant workers. This made it possible for wage workers to view migration as a way of earning and accumulating a useful lump sum, rather than simply surviving through food payments during the period of work, as had taken place in the past. However, there was no general move away from the compulsion to earn a wage through hard manual labour. Through the testimonies, we explore the ambivalence of migrant workers towards changes in the relations of production at home and at the destination workplace.  相似文献
