We present data from an international survey of scientists working at volcanic observatories concerning eruption likelihoods. The scientists were asked a range of questions using different types of phrasing. The data suggest that the phrasing of questions affects the ways in which probabilities are estimated. In total, 71% of respondents (N = 70) exhibited some form of inconsistency in their answers between and/or within different question formats. The data also allow for an analysis of the use of scaling in probabilistic assessment, and the use of quantitative versus verbal risk measurements. However, some respondents were uncomfortable with providing any numerical probability estimate, perhaps suggesting that they considered the uncertainty too high for meaningful judgements to be made.  相似文献

Private agents make large contributions to networks of conserved land, but little is known about how private agents’ decisions might be altered by government actions. This paper explores the impact of public conservation and public policy on the quantity and configuration of private land conservation and the extent to which the social optimum is reached. Because land conservation benefits often have thresholds and spatial characteristics, we consider the impact of different land conservation benefit functions on the patterns of conservation created by the interaction of private and public agents. We find that public conservation crowds private conservation in or out depending on whether marginal conservation benefits increase or decrease with total acreage, and crowding out is mitigated by the presence of budget constraints. We show how land conservation agents might interact strategically in space depending on preferences over fragmentation, and we explore that spatial strategic interaction in a case with a regional land trust and a case with hot-spot parcels. We identify when government policies, such as agglomeration bonuses and mitigating coordination costs, are most likely to increase the social benefits provided by private land conservation agents.  相似文献

During the COVID-19 pandemic, different nations have adopted a variety of response strategies to fight and contain the new coronavirus. Such national response strategies can be classified into three categories based on their underlying philosophy: strict control with unlimited resources, relentless contribution with limited resources, and rough rationality with limited resources. We discuss the philosophies, characteristics, and performances of the three response strategies and when they should be adopted. We also examine what marketing innovation strategies enterprises should adopt to survive and grow their businesses in both the short and long term. This study provides important strategic implications for national policymakers and enterprises on the use of response strategies as well as marketing innovation tactics and strategies to be used both during and after the pandemic.  相似文献

Celebrity has a powerful material presence in contemporary consumer culture but its surface aesthetic resonates with the promise of deeper meanings. This Marketplace Icon contribution speculates on the iconicity of celebrity from a spiritual perspective. The social value or authenticity of contemporary celebrity, and the social processes through which it emerges, are matters of debate amongst researchers and competing approaches include field theory, functionalism, and anthropologically inflected accounts of the latent need for ritual, myth and spiritual fulfillment evinced by celebrity “worship.” We focus on the latter area as a partial explanation of the phenomenon whereby so many consumers seem so enchanted by images of, and stories about, individuals with whom they, or we, often have little in common. We speculate that the powerful presence of celebrity in Western consumer culture to some extent reflects and exploits a latent need for myths of redemption through the iconic character of many, though by no means all, manifestations of celebrity consumption.  相似文献

Eco-labels are being used more frequently in the marketplace. Recently, carbon-neutral labels have emerged on product packaging and advertisements as a popular form of eco-label. How consumers view these specific labels is of both conceptual and practical interest. Therefore, in a mixed-experimental design building on congruity theory and Deighton's two-step model of advertising effectiveness, the authors examine how consumers view the credibility and environmental concern of companies who use these labels, as well as their resulting purchase intentions. A 2(product) × 2(label) × 3(information) mixed design was used to examine consumer perceptions and behavior intentions. Product category (environmentally neutral vs. environmentally harmful) was a within-subjects factor; the presence/absence of the carbon-neutral label and information (positive/negative/control) was both manipulated between-subjects factors. Results show that the presence of a carbon-neutral label in an advertisement, regardless of the type of product, leads to more favorable perceptions of company environmental concern. However, there is a more pronounced increase in consumer perceptions of company environmental concern for an environmentally harmful product than for an environmentally neutral product.  相似文献

This study tested the relationships between store and customer characteristics with perceived value and customer loyalty in retailing in China. Survey data were collected from shoppers in department stores (n=200) and supermarkets (n=200) in the tier 2 coastal city of Tianjin. Data for each type of store were analysed separately using structural models. In supermarkets, value was predicted by quality and price, but for department stores, only the customer orientation of the store was significant, suggesting that customers seek different shopping experiences in each context. In each case, value mediated the links to loyalty and, for supermarkets, choice of merchandise and consumer time pressure demonstrated direct links to loyalty. The paper discusses the implications of the findings, and concludes with possible future research.  相似文献

Technological advances enable sellers to identify relationships among offered goods. Sellers can leverage this information through pricing strategies such as bundling and sequential pricing. While these strategies have primarily been studied under monopoly assumptions, the strategies are available to competitive firms as well. This paper reports on a series of laboratory experiments comparing bundling and sequential pricing while varying the underlying relationship between the goods in markets where a fraction of buyers comparison shop. The results indicate that sequential pricing is generally as profitable to the seller; however, there is evidence that sequential pricing may be more harmful to consumers than bundling when the goods have complementary values or the buyer’s values are positively correlated.  相似文献
