Researchers have widely studied the nexus between corporate environmental (“green”) policy and its green performance and firm financial performance, but with mixed findings. A potential explanation for these mixed findings is the focus of extant studies on the direct and immediate impact of environmental performance on financial performance to the exclusion of firm‐specific boundary conditions. Furthermore, all prior research study the effect of environmental performance on either stock market‐based performance measures (i.e., stock return) or accounting‐based performance measures (i.e., return on assets). A missing third dimension of firm performance, product–market‐based performance (i.e., market share), has so far remained unexplored despite representing a crucial objective when innovating. Using Newsweek's annual green ranking as a novel measure of environmental performance for a panel of U.S. firms from 2010 to 2015, this paper attempts to fill these voids in the literature. The results show a positive relationship between firms' environmental performance and market share as a measure of product–market‐based performance. The findings further demonstrate that this relationship is positively moderated by the level of customer awareness and innovativeness of the firm: The higher the level of awareness of a firm's environmental credentials and innovativeness, the stronger the effects of environmental performance on market share. Our results are robust against endogeneity concerns and alternative measures of firm financial and environmental performance.  相似文献

In social choice settings with linear preferences, random dictatorship is known to be the only social decision scheme satisfying strategyproofness and ex post efficiency. When also allowing indifferences, random serial dictatorship (RSD) is a well-known generalization of random dictatorship that retains both properties. RSD has been particularly successful in the special domain of random assignment where indifferences are unavoidable. While executing RSD is obviously feasible, we show that computing the resulting probabilities is #P-complete, and thus intractable, both in the context of voting and assignment.  相似文献

We show that changes in expectations of future income driven by exogenous factors (such as the discovery of oil and an increase in global demand for natural resources) can cause movements in the real exchange rate (RER) in excess of, and sometimes even in the opposite direction to, what one would expect given the changes in current income. We provide both a theoretical model and empirical evidence of this. In particular, we show that the signing of numerous production sharing agreements (PSAs) between the government of Azerbaijan and foreign oil companies in 1994–1998 fueled expectations of higher future incomes, resulting in a considerable appreciation of the RER. Some of these PSAs subsequently failed or ran into difficulties, which led to a downward revision of expected future income and a depreciation of the RER in 1999–2003, even though the current income started to rise, due to an increase in the current oil revenue.  相似文献

Recently, goal programming (GP) has been discussed in the literature as an alternative to linear programming, particularly in decision-making environments involving multiple objectives. In this paper we present an overview of the different GP formulations, their assumptions, limitations, and implications for agricultural decision making. Furthermore, a new insight into the interpretation of duality in GP is discussed. The concept of "standardized dual variables" which provides a more meaningful interpretation of shadow prices in GP is introduced. A simple but realistic farm agricultural planning example is used to illustrate the analysis.
Récemment, la technique de programmation appellée "goal programming" ou "GP" a été presentée dans la literature comme une alternative à la programmation Iinéaire, particulièrement dans les situations òu le procés de décision est basé sur plusieurs objectifs simultanés. Dans cet article nous présentons une vue génerale des différentes formes de la "GP;" leurs hypothèses de base. Ieurs limitations, et leurs implications pour le procés de decision agricole, une nouvelle intérpretation de la dualité en "GP" est proposée. En particulier, le concept de "variables duales standardisées" est introduit, ce qui permet une interpretation plus significative des prix de reference en "GP." Finalement. un exemple simple mais réaliste de planification agrcole a l' échelle d' une ferme est pour élucider utilisé l' analyse.  相似文献

The article points out that, although the relative importance of the agricultural sector in the Arab world is declining as the importance of oil rises, it is still vital to Arab countries. Selfsufficiency in agriculture is desirable because of a possible cutoff of food imports for political reasons by the food-exporting countries. The article examines the possibilities for Arab selfsufficiency and suggests several alternative strategies.  相似文献

Marriage life is an abstract and complex matter that even for husband and wife themselves find not as easy as they expect in achieving a long term marriage. The differences between spouses may lead to disabilities to see clearly their spouse needs. The disabilities may implicate to a bigger issue which is loyalty. In this study, the analysis have been carried out to determine priority needs in marriage for initiating loyalty. In using Quality Function (QFD) adaptations, we created “Quality_Marriage Deployment” by deploy the marriage in quality perspectives. As result, we succeed to identify 7 of 15 variables with the lowest performance value that make them as the priority needs. Based on the needs, we proposed some actions both in perspective of marriage and quality knowledge. Furthermore, the result shows Quality_Marriage Deployment matrix may generally easier for any user to read and know directly what variables need to be improved. Each solutions were presented to allow the users to act in a more efficient and effective in time and energy.  相似文献

This study assesses the extent of accounting harmony in Europe prior to the recent switch to IFRS, by presuming that accounting is harmonized when 'all firms operating in similar circumstances adopt the same accounting treatment for similar transactions regardless of their domicile'. The policies studied concern inventory, depreciation and goodwill, and the odds of using alternative accounting methods are predicted by logistic regression. The empirical results suggest that, while international exposure and firm size are significant factors, country effects are considerably greater than sector effects, which is inconsistent with harmonized accounting.  相似文献

This study reports the results of an opinion survey of a Malaysian managerial subelite, potential future business and government leaders. Their responses to propositions put forth in a detailed questionnaire indicate that they have values conforming to those associated with Western bureaucratic society. The results of this 1982 survey are discussed under the topics of attitudes toward women, attitudes toward business and religion, station in life, and peer trust levels.Bernard Sarachek is with the University of Missouri-Kansas City.

This investigates the impact of customer attitude and judgment regarding conventional and Islamic banking system in Pakistan. This study attempts to find out, how the customers of Islamic banks perceive about Islamic banking practices in terms of Shariah compliance and conventional banking system regarding earning more profits. This study consists on primary data through a well design questionnaire. Four hundred and thirty (430) questionnaires were distributed among different customers of all three types of banking, such as Islamic, conventional and stand-alone branches in order to investigate customer’s attitude and judgment toward banking system. The findings indicate that overall 28% of Islamic banking customers don’t know the essential concept of Islamic financial institution’s in Pakistan. Furthermore, 54% customers of conventional banking show their interest to convert their accounts toward Islamic banks.
