New policy approaches to facilitate the co-existence of wildlife and livestock are needed for situations where predation incidents
greatly impact households’ income and retaliatory killing threatens endangered carnivore species’ survival. In this paper,
models are developed to assess how two alternative policy approaches impact a herder’s decisions on carnivore hunting and
livestock protection. We find that while the well-established ex-post compensation policy induces suboptimal livestock protection
it can generate sufficient incentives for the herder to refrain from hunting so that the carnivore population reaches its
socially optimal level. Performance payments are proposed as alternative policy. They are found not to distort livestock protection
incentives and can also help achieve a socially optimal carnivore population level. Which of the two scheme types gives rise
to less cost is ambiguous. An empirical analysis of the model with data from tiger-livestock conflicts in India is presented. 相似文献

We propose and study a new method to nonparametrically estimate a discontinuity of a regression function. The optimal rate of convergence n −1 is obtained under minimal assumptions. No smoothing is required. 相似文献

With rapid globalization, multinational firms are sending a growing number of employees on foreign assignments. A growing body of research attests to the interest in the stress experienced by these expatriates. The current study focused on a subject rarely addressed in expatriate stress research, namely burnout. Its goals were to demonstrate: (1) the relevance of burnout to expatriates; (2) the difference between stress and burnout; (3) the role played by the perceived importance of expatriates' work; (4) the relevance of existential theory as a theoretical backdrop. The study included 233 Israeli expatriates who responded to a questionnaire. Findings revealed high level of stress, low level of burnout and very high perceived work importance. Hierarchical regression showed that importance moderated the effect of stress on burnout. There were differences between the correlates of stress and burnout, especially work importance, which was negatively correlated with burnout and positively correlated with stress. 相似文献

We study the effects of consumer perceptions of four types of corporate social responsibility (CSR) activities on their behavioral loyalty toward retailers. The four activities are environmental friendliness, community support, selling locally produced products, and treating employees fairly. Behavioral loyalty is measured by share-of-wallet (SOW). We control for other retailer attributes that drive attitudes and SOW, and examine how the market is segmented in terms of consumer response. We partition the total effect of CSR on SOW into a direct effect and an indirect effect mediated through attitude towards the store. These effects differ by CSR activity and customer segment. The effects on attitude are positive and positive attitude enhances SOW, so the indirect effects on SOW are positive. While we generally find positive total effects, the total effect of one of the CSR activities, environmental friendliness, is significantly negative for one group of consumers. The magnitude of CSR's total impact on SOW is not only statistically significant but also managerially meaningful in an industry where every share point carries a substantial dollar amount. We characterize the customer segments and conclude with implications for how best a retailer can manage its CSR initiatives. 相似文献

We examine smallholder farmers’ willingness to pay for agricultural technology and whether information is a constraint to adoption of certified maize seed in Northern Uganda. The uptake of improved maize varieties by smallholder farmers in Uganda remains persistently low, despite the higher yield potential compared to traditional varieties. A recently growing body of literature identifies information constraints as a potential barrier to adoption of agricultural technologies. We used incentive compatible Becker‐DeGroot‐Marschak auctions to elicit willingness to pay for quality assured improved maize seed by 1,009 smallholder farmers, and conducted a randomised evaluation to test the effect of an information intervention on farmers’ knowledge of seed certification. Our results show that the randomised information treatment enhanced farmers’ knowledge of certified seed. However, using the information treatment as an instrumental variable for knowledge, we find no evidence of a causal effect of knowledge on willingness to pay, suggesting that even though farmers are information constrained, this constraint does not affect adoption of certified seed directly. Nevertheless, only 14% of sampled farmers were willing to pay the market price, which corresponds closely with actual observed demand for certified seed in the previous season. This suggests that there are other barriers to adoption than information and awareness. 相似文献

Current literature on ethical leadership and unethical leadership reflects a Western-based private sector perspective, pointing toward a compliance-oriented understanding of ethical and unethical leadership. As today’s executives increasingly have to ethically lead across different cultures and sectors, it becomes vitally important to develop a more holistic picture how ethical and unethical leadership is perceived in the Western and Eastern cultural cluster and the private and the public/social sector. Addressing this issue, the present study aims to identify cross-cultural and cross-sectoral commonalities and differences in international executives’ perceptions of ethical and unethical leadership. Findings from in-depth interviews (N = 36) with executives from Western and Eastern cultures working in the private or the public/social sector reveal collectively held perceptions of ethical leadership (including leader honesty, integrity, concern for responsibility/sustainability, and people orientation) and of unethical leadership (referring to leader dishonesty, corruption, egocentrism, and manipulation). Results indicate limited support for a compliance-oriented perspective on ethical and unethical leadership but yield a much greater trend toward a value-oriented perspective. Concrete practice examples illustrate these different perspectives. Cultural and sectoral particularities of executive perceptions of ethical and unethical leadership are discussed. 相似文献

This article reports the results of student vacation travel choice analysis using a reference dependent model of airline fare preferences. Findings suggests, as expected, that the preferences/utility decreases with increasing levels of cost. The evaluation of the airfare, however, becomes significantly more critical in the regime were low-fare airlines are more expensive than the regular airlines, meaning that price sensitivity for low-fare airlines is higher in this case. Part-worth utility functions for airfare as part of a more general portfolio model of vacation decisions of students suggest that indeed a reference dependent model captures such regimes in utility space. 相似文献

This study examines how online display ads, alone or in combination with more conventional media (television and print), can help drive sales in the consumer packaged goods (CPG) sector. It also assesses how the combined sales effect of online and offline ads depends on the volatility of their expenditures over time. We explore these relations for 154 brands across 68 Dutch CPG product categories. We find that, even though display ads are not effective for the “average” CPG brand, they do have a significant impact for a sizable, and considerably larger than expected by chance, subset of brands. Importantly, this impact depends on the type of product. While display ads are found to be ineffective for low-involvement utilitarian products, they can significantly enhance sales for other CPG product types. Moreover, the effect depends on whether they are used in combination with other media: while display ads are best used as a stand-alone medium for high-involvement utilitarian products, it is better to combine them with traditional media for hedonic products. Finally, the long-term effectiveness of display messages increases significantly when they are spread more evenly in time. 相似文献
