I propose applying the Mixed Data Sampling (MIDAS) framework to forecast Value at Risk (VaR) and Expected shortfall (ES). The new methods exploit the serial dependence on short-horizon returns to directly forecast the tail dynamics of the desired horizon. I perform a comprehensive comparison of out-of-sample VaR and ES forecasts with established models for a wide range of financial assets and backtests. The MIDAS-based models significantly outperform traditional GARCH-based forecasts and alternative conditional quantile specifications, especially in terms of multi-day forecast horizons. My analysis advocates models that feature asymmetric conditional quantiles and the use of the Asymmetric Laplace density to jointly estimate VaR and ES.  相似文献

Corporate social responsibility (CSR) increasingly receives attention from managers and researchers, especially in the area of consumer perception and response of CSR. However, most of this research was conducted in the context of developed countries. It shows that research on consumer perception towards CSR in developing countries needs to be developed. This paper will examine consumer perception in the developing country of Indonesia. This research produced mixed results, suggesting that CSR is still a concept waiting to be applied in the developing country. Consumers are often unaware and unsupportive towards CSR. This is the opposite finding of consumer perception in developed countries, where most consumers are willing to support CSR launched by corporations. Nevertheless, there is an interesting finding: When consumers have to buy similar products with the same price and quality, CSR could be the determining factor. They would buy from the firm that has a socially responsible reputation.  相似文献

Historically, soil, land, climatic constraints and individuals’ skills all contributed to the characteristics of regional food. Food, however, is also subject to the influences of colonialism, immigration, cultural exchange, international trade, improved distribution and technology. British food is constantly evolving in order to fulfil the demands of each generation. Thus, the concept of an authentic British food product is becoming increasingly unclear. This paper therefore addresses what today British consumers actually perceive to be authentic British foods. Results of an exploratory qualitative study are reviewed. Five focus groups were conducted with individuals responsible for half or more of their household’s shopping. The groups incorporated consumers with a range of demographic and economic characteristics. The data gathered from the focus groups revealed that British perceptions of authenticity relate to both artisan as well mass‐produced, branded products. In addition, five dimensions affecting consumer perceptions of an authentic British food product were identified, including: uniqueness to Britain, a cultural or traditional association with Britain, characteristics of the production process, the presence of an authority and specific extrinsic characteristics of the product. The findings have implications for product differentiation and communication, for producers and retailers and also for independent trade associations.  相似文献

Abstract

Marketing for sustainable tourism primarily attracts customers with a biospheric–altruistic value orientation. To reach a broader consumer group and also persuade people with a self-enhancement orientation to book sustainable hotels, the effectiveness of three different communication styles (emotionality levels, amount of sustainability information and inclusion of a label) is investigated, considering the consumer’s value orientation. An experiment with 337 participants was conducted to analyze the effects of communication on consumer perceptions of well-being and credibility. Multigroup structural equation modeling was used to compare the impacts of communication style on participant’s attitude toward booking a sustainable hotel, mediated by well-being and credibility. The results highlight significantly different communication effects among the two contrasting target groups. Consumers who are highly interested in sustainability (biospheric–altruistic value orientation) are persuaded by messages that include details about the hotel’s sustainability performance, in order to increase the social–environmental well-being, whereas for customers who are less interested in sustainability (self-enhancement value orientation), a self-referential emotionally communication is essential, as it increases the emotional well-being. Inconsistent findings regarding the role of communication in raising the perception of credibility were obtained.  相似文献

The purpose of this article is to explore the video-gaming experience as a novel consumption occasion for snack foods and to provide insights into responsible marketing strategy development. Consumers' desired food product attributes, their motivating conditions to snack while gaming, and the environment in which this takes place are explored qualitatively through 14 in-depth interviews and 10 separate points of field observation. The findings indicate certain unhealthy food products are valued during the occasion for their social hedonic appeal but also for the basic function of fuelling long marathons of concentration and competition. Results are used to inform strategic considerations which are presented using the traditional marketing mix framework of product, promotion, price, and place of distribution. Therein, management is cautioned toward the obesogenic elements of the consumption occasion and this is a critical consideration throughout. Management is strongly advised to develop and promote healthier snacks as part of facilitating an enabling environment for sustainable food choices.  相似文献

ABSTRACT

This study investigates the impacts of perceived security and consumer innovativeness on online travel shopping. A survey questionnaire was used to collect data and a total of 283 questionnaires were used for data analysis. The mechanism of perceived security and consumer innovativeness was then identified. The study results indicate that: (1) higher perceived security increases the perception of website image and trust; (2) consumers with a higher level of innovativeness tend to trust travel websites; (3) website image has a mediating effect between perceived security and trust; and (4) trust has a mediating effect between website image and e-loyalty.  相似文献

Many businesses operate long hours that often include nights and weekends to accommodate consumers. However, a few businesses maintain a closed-on-Sunday policy and do so while still operating successfully although closed-on-Sunday policies mean forgoing potential sales hours. As most Christian faiths consider the Sabbath as a day of rest, an oft-used rationalization for the success of businesses maintaining this policy is that they must be supported by consumers with strong religious beliefs, who appreciate the message sent by the company and as a result perceive the company favorably. The purpose of this paper was to investigate whether consumers' religious commitment influences their ethical judgment of a company's closed-on-Sunday policy and to determine whether this ethical judgment impacts a company's corporate or brand image and consumer loyalty intentions. The results suggest that consumers with higher levels of intra-personal religious commitment are more likely to hold favorable ethical judgments of closed-on-Sunday corporate policies. In addition, favorable ethical judgments of closed-on-Sunday corporate policies are likely to positively influence corporate image. A more positive corporate image ultimately results in higher consumer loyalty intentions.  相似文献

This study’s purpose was to assess the impact of temporal, seasonal and calendar effects, on guests’ comments in hospitality. The current study analyzed the differences in food and service quality using guests’ comments collected by a national restaurant firm over a period of one year. Comments were analyzed for season of the year, weekend versus weekday, busy versus slow days, and day of the week. Findings included statistically significant differences of (positive and negative) comments between day of week and busy/slow periods. Most notably, positive food quality comments were submitted more often during busy periods, indicating a possible need for training of employees who work during slow periods.  相似文献
