This work presents the participation factor and the valuation of a first-generation structured product with European call options on the Eurostoxx, when the uncertainty of the yields is modeled through log-stable processes. The basic statistics of the index yields are also exposed, the α-stable parameters are estimated, and the valuation of the of the structured models is compared through the log-stable and log-Gaussian models using inputs from the bond markets; concluding that investors obtain higher yields than those of the bond market through both models, and that the differences of the yields depend on the participation factor and on the value of the index at the time of liquidation. 相似文献

Natural personal care products are gaining popularity due to their benefits in terms of health and well-being. However, consumers are wary of these products and are guided by the fake news circulating about them. Since natural product consumption offers several personal and environmental benefits, it would be worthwhile to understand consumers’ tendency to let fake news influence their consumption decisions. Accordingly, the current study examined the association of fake news and purchasing behaviour towards natural personal care products, utilising Stimulus-Organism-Behaviour-Consequence (SOBC) as the theoretical framework. The study proposed openness to change as the stimulus, perceived benefits and perceived risks as organismic internal states, purchase intentions as the behaviour, and the propensity of believing and acting on fake news as the consequence, which is further associated with system trust. The model was tested by analysing data collected from 390 existing consumers, considering the moderation effect of brand trust and controlling the effect of age and gender. The findings confirmed that openness to change is associated with perceived benefits and risks. Furthermore, perceived benefits and system trust are associated with purchase intentions, which are, in turn, associated with the propensity of believing and acting on fake news. The study presents several novel contributions to theory and practice. 相似文献

Tourism products differ from ordinary retail products in terms of the spatial and temporal separation between the purchase and experiencing the product. Despite its importance, temporal separation has not drawn much attention in tourism research. The main objective of this study is to understand the effects of temporal sunk costs on potential travelers' cancellation intentions, in addition to monetary sunk costs. The results of this study suggested the possibility that temporal costs can be converted into monetary costs, but the conversion relationship may not be linear. This study also indicated that travelers' intentions to cancel a travel product decreased as the temporal and monetary sunk costs increased. Further, prior experience moderated the relationship when temporal sunk costs were involved, suggesting that repeat visitors' intentions to cancel their reservations are more influenced by temporal sunk costs than first-time visitors. Further discussion and implications are provided in the main body of this paper. 相似文献

Based on an extended case study of a large‐scale tomato farm in northern Limpopo province, the paper examines how the restructuring of agriculture transforms the sexual economy through shifts in the composition of labour and management practices on farms in this area. The employment of Zimbabwean migrants, rather than relatively permanent Venda families, suggests a potentially greater variety of people participating in the sexual economy. While families as units of employment have declined, black supervisors increasingly serve as a primary locus of coercion on the farm and in the sexual economy. The monetization of erstwhile paternalistic services places pressure on women to earn income however they can, including transactional sex. Contested interpretations over the causes of infant deaths on the farm, in the form of hygiene, blood‐mixing and infanticide, provide an ethnographic framework for a deeper analysis of the sexual economy and its social effects. While the sexual economy presents opportunities for women to increase their income, it also exposes them to the risks of HIV/AIDS and unwanted pregnancies, resulting in contradictory implications for the status of women on farms. 相似文献

In investigating consumers’ intentions to re-purchase organic personal care products (PCP), this study extends the theory of planned behaviour by including perceived value dimensions as the antecedents of attitude in the model. The findings revealed that most of the hypothesised relationships linking the consumer perceived value constructs (namely, health, safety, hedonic and environmental) with attitude towards the rebuying of organic PCP, were supported. Also, better product knowledge about organic PCP would lead to more positive attitudes towards re-purchasing the product. In contrast, social value was not important in predicting attitude. Similarly, the influence of subjective norm on rebuying intention was not supported. In terms of ranking of importance with regards to prediction of re-purchasing intention, attitude was the most important predictor followed by perceived behavioural control, product knowledge, hedonic value, environmental value and safety value. 相似文献

Despite the rapidly increasing number of tourists with disabilities, which is known to have a strong nexus with senior travel market, tourism industry has paid little attention to the distinctive preferences of these tourists for accessible travel products. Using a sample of Koreans with mobility disabilities, this study aims to better understand how they make decisions to choose optimal accessible travel products. The results of the choice experiment indicate that respondents place the heaviest weight on the accessibility of accommodation facilities for their maximization of travel satisfaction. The results also suggest that tourists with disabilities show higher willingness-to-pay values on particular tour buses equipped with more accessibility devices. Based on study findings, this study provides several management implications that help tourism professionals develop appropriate accessible travel products for their clientele with disabilities. 相似文献
