Prior research suggests that adoption decisions are primarily based on product features and experiential opportunities, like trial and observation. Our research follows inquiries that identify anticipated regret (AR) as an emotion integral to consumer decision making. Prior research and current retailing practice assume that AR can be alleviated by compelling product attribute-based rationales for immediate purchase. These rationales often take the form of direct attribute comparisons between the current best and the future technologies. Counter-intuitively, we find that giving consumers attribute-based justifications for immediate purchase produces a uniform level of AR and purchase delay regardless of the perceived rate of innovation (PRI). However, under conditions of low PRI and no justification, AR decreases significantly. A clear implication of our findings is that firms marketing current technology should not rush to provide consumers with justifications for immediate upgrade since such communications will remind consumers of what they might miss if they adopt now, resulting in increased AR and purchase delays. Instead, we suggest that retailers focus promotional efforts on highlighting the hedonic benefits consumers experience by adopting today.  相似文献

被业界称为"一石三鸟且重大利好"的国有股转持政策体现了以行政为主导的部门利益分配,表面调和了部门矛盾但却难以真正实现各利益主体的协调运作,隐含着证券市场是一个相对边缘化的市场,并且社保基金作为财务投资者改善上市公司的法人治理结构难度极大,国有创投遭遇进退维谷的两难困境。长期来看,国有股转持是证券市场的利空措施,而当务之急是尽快出台国有股转持的配套细则。  相似文献

We investigate the relationship between the degree of competition and the stability of collusive behaviour, by introducing the element of relative performance in the objective functions of the firms. We show that an increase in the degree of competition destabilizes the collusion. This relation differs starkly in the standard symmetric Cournot and Bertrand duopoly models, with the former being more unstable than the latter.  相似文献

In 2007–2008, when food prices started to increase dramatically, purchasing power parity of consumers, especially the urban poor, started to decrease automatically. High food prices were argued to cause poverty, hunger, and food riots among urban populations. Henceforward, “food crisis” became a new storyline in the current debate. In contrast, in the pre-2007 period, when rural farmers had been facing negative welfare effects of low food prices for many years, there were no crisis talks. This article analyzes different media coverage of urban consumers and rural producers under changes in relative incomes for the 2000–2013 period and propounds media bias on the food crisis debate by using content analysis and the OLS regression model.  相似文献

Many economic and evolutionary theories have modeled cooperation as the evolutionary outcome of decisions made by autonomous, self-interested agents operating in a social vacuum. In this paper we consider the implications for cooperative interactions when prior social structures and corresponding social norms exist. In particular we investigate the influence of social rank/status on perceptions of fairness and tolerance of cheating. We review evidence from a series of experiments employing the Wason selection task (a test of conditional reasoning) and the ledger task (a decision making task) suggesting that people cued to adopt a perspective of high social rank are more tolerant of cheating and simultaneously believe that they have been more fairly treated (even when cheated) than people cued to adopt a perspective of low social rank. However, the evidence also suggests interesting cross-cultural differences in perceptions of fairness and tolerance of cheating in ranked relationships. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献
