In-store displays aim to boost sales of both utilitarian and hedonic products. Noting typical differences in the information processing and purchase behavior evoked by these product types, and building on congruency theory principles, the authors propose that different types of in-store displays (i.e., island, end-of-aisle, or shelf signage) are more appropriate for utilitarian versus hedonic products, and the use of price or product promotions might reinforce these effects. With a database that combines three data sources (scanner, observational, and survey), this article presents an analysis of a market share model at the SKU level. The results confirm that in-store displays have differential effects on sales, depending on their characteristics; congruency between the decision-making process of utilitarian versus hedonic products and the characteristics of in-store display types moderates their effectiveness in terms of SKU sales. Shelf signage strongly increases the sales of utilitarian products, whereas island and end-of-aisle displays increase sales of hedonic product categories more effectively. The use of congruent promotions creates synergistic influences that reinforce these effects. In particular, price promotions improve the impact of shelf signage on utilitarian products, and product promotions strengthen the impacts of island and end-of-aisle displays on hedonic products. These results extend prior research on in-store marketing actions and the nature of utilitarian versus hedonic products, as well as providing recommendations for retailers and manufacturers seeking to optimize their retail space and commercial budgets.  相似文献

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.  相似文献

Successful organizations have dynamic capabilities that are aligned with their competitive environments. As competitive environments globalize, the dynamic capabilities driven by managers with multicultural backgrounds are increasingly relevant. These managers are more likely to seize cognitively distant opportunities than monocultural managers. Using panel analysis of multilevel data from 355 elite football (soccer) teams, we find support for a moderated relationship among the degree of globalization in the competitive environment, the multicultural background of team managers, and team performance. When the competitive environment is highly global, teams with multicultural managers outperform teams with monocultural managers. When the competitive environment is less global, the reverse is true. The same effect holds when tested both cross-sectionally and longitudinally.  相似文献

Advertising situated in environments where people congregate or pass through on their way to somewhere else benefit from being placed in such high traffic areas. However, these strategically placed ads also suffer from conditions of human crowding that prevents them from being noticed and processed. We undertake a study of place-based advertising in a shopping mall using facial recognition software to determine the effect of human density on the attention directed to advertising. We find that as human density increases, attention to advertising decreases, but only to a point where it begins to increase again. Our research also finds that human density plays a moderating role on the motivation to process advertising.  相似文献

[目的]随着农村城镇化进程的加快,由此引发的农村居住地生态环境恶化已成为制约农业和农村经济可持续发展的瓶颈,加强农村居住地生态环境保护和治理,是目前亟待解决的重要问题。研究分析农村居住地生态环境影响因素,为有效改善居住地生态环境提供重要理论依据。[方法]以陕西省为主要研究区域,采用层次分析法,构建矩阵模型,研究影响陕西省农村居住地生态环境的农民因素、生产活动和政府因素3个层次,包括周边乡镇企业废物排放、农用投入品的使用、畜禽养殖业废物排放、人均消费支出、农村人均家庭纯收入、农村家庭恩格尔系数、环保意识、政府监管力度、环境保护财政支出,相关政策法规等10个因素所占权重,得到不同因素的重要性排序。[结果]乡镇企业废物排放、农用投入品的使用、农村人均家庭纯收入和农村人均消费支出是影响农村居住地生态环境的主要因素,且重要性排序为乡镇企业废物排放农用投入品的使用农村人均家庭纯收入农村人均消费支出。[结论]加强乡镇企业废物排放管理和农用投入品的生产和使用审查,降低不必要的消费支出,同时为农民提供更多的就业机会,提高人均家庭村收入,是目前改善农村居住地生态环境的有效措施,为农民提供一个安全舒适的居住场所,这也将有利于农村经济的可持续发展。  相似文献

Stock markets can be interpreted to a certain extent as prediction markets, since they can incorporate and represent the different opinions of investors who disagree on the implications of the available information on past and expected events and trade on their beliefs in order to achieve profits. Many forecast models have been developed for predicting the future state of stock markets, with the aim of using this knowledge in a trading strategy. This paper interprets the classification of the S&P500 open-to-close returns as a four-class problem. We compare four trading strategies based on a random forest classifier to a buy-and-hold strategy. The results show that predicting the classes with higher absolute returns, ‘strong positive’ and ‘strong negative’, contributed the most to the trading strategies on average. This finding can help shed light on the way in which using additional event outcomes for the classification beyond a simple upward or downward movement can potentially improve a trading strategy.  相似文献

The organizational design literature strongly supports the notion of “structure follows strategy”, and suggests that a misfit between the two has a negative effect on performance. Building on this line of argument, we examine to what extent the (mis)fit between purchasing strategy and purchasing structure impacts purchasing performance. We focus on cost and innovation purchase category strategies, and examine how the deviation from an ideal purchasing structure defined along three dimensions (centralization, formalization, and cross-functionality) impacts purchasing performance. Analysing data collected from 469 firms in ten countries, we demonstrate that a strategy-structure misfit negatively impacts purchasing performance in both cost and innovation strategies. We also find that purchasing proficiency is a mediator in this relationship between misfit and performance. Our findings aid managerial decision making by empirically validating the necessity of having the right purchasing structure for successfully executing different purchasing strategies.  相似文献
