本文运用经验分布函数对中、美、英、日四国股市的暴涨暴跌进行了界定,并对四国股市暴涨暴跌的表现进行了比较分析。相比其它三国,中国股市在过去15年间成长性最强,暴涨暴跌的幅度最大,表现出较强的"政策驱动型"特征。美、英、日股市的暴涨暴跌呈现出明显的"市场和事件驱动型"特征。英国和美国股市波动呈现出较强的同步性,但日本股市波动较为独特。政策建议上,各国应通力合作,以应对全球系统性风险对股市的影响;中国政府应加强股市的市场化建设,同时谨慎开放资本市场。 相似文献

We analyze history-based price discrimination in an asymmetric industry, where an incumbent, protected by switching costs, faces an entrant who does not have access to information about consumers’ purchase histories. We demonstrate that consumer surplus is higher with uniform pricing than with history-based price discrimination. We find that the entry decision is invariant to whether the incumbent implements history-based pricing or uniform pricing. This implies that the potential abuse of market dominance imposed by history-based price discrimination is exploitation, not exclusion. Finally, we establish that the profit gain to the incumbent from history-based pricing exceeds the associated loss to consumers. 相似文献

The VoIP (Voice over Internet Protocol) market in Korea is showing rapid growth since domestic carriers initiated the service in 2006. These carriers are now seeking new revenue sources from various convergence services and are increasing investment into VoIP. In particular, local exchange carriers (LECs), formerly reluctant to invest in technologies that would cannibalize their local telephone revenue, have started to invest in VoIP, in recognition of the current convergence of media and the telecommunications industry, as well as in the face of intensifying competition. In this study, we determined that VoIP call rates and landline telephony call rates were the most important factors affecting VoIP call demand, in addition to network externality. We also verified that landline telephony is no longer a supplement to VoIP, but rather, a substitute that has considerable influence on VoIP call demand. Empirical evidence is expected to be considered in policy decision making on current issues in the IT industry, such as access prices or competitiveness assessment. The current empirical analysis on the Korean VoIP industry and the adherence to lessons learned from policy enforcement should provide valuable information to countries seeking to develop their own VoIP industries, as well as to businesses developing new strategies based on the VoIP market. 相似文献

We discuss the reasons why this call for papers was issued and describe the process of selecting the three articles presented in this special section. We argue that maximizing stakeholder welfare and not just consumption maybe a new goal for marketing that will be consistent with emerging societal trends. Three articles on volunteerism, price assurances, and direct-to-consumer advertising result from our call and are presented in this section. This introduction is an overview of the three articles. 相似文献

I Have Paid Less Than You! The Emotional and Behavioral Consequences of Advantaged Price Inequality 总被引:2,自引:0,他引:2
Katja Gelbrich 《Journal of Retailing》2011,87(2):207-224
This study examines the emotion blends and the subsequent customer reactions that occur in advantaged price inequality situations, that is, when consumers learn that retailers charged them a lower price than what the same retailers charged another customer. Drawing on the appraisal theories of emotion and on social comparison theory, an experiment (n = 272) and a field study (n = 261) are conducted. The results reveal that in advantaged price inequality situations, customers experience a host of positive and negative emotions depending on two factors: the quality of relationship that the customer has with a disadvantaged other customer (neutral, positive, or negative) and the attribution of agency for the price advantage (situational attribution to competition, external attribution to store policies, or internal attribution to customer abilities). Positive emotions include happiness, gratitude, pride, and malicious joy; while negative emotions include pity, outrage, and guilt. These emotions are shown to mediate the occurrence of customer reactions (i.e., customer satisfaction, loyalty, WOM referral, and WOM activity). The article concludes with theoretical implications and recommendations for retail practitioners on how to use dynamic pricing. 相似文献

The relationship between store image and store brand equity: A conceptual framework and evidence from hypermarkets 总被引:1,自引:0,他引:1
Retailers are making considerable efforts to improve their brand management. The challenge they face, however, is how best to integrate coherently their stores, as brands, and their various distributor brands (store brands, private labels, etc.), in order to increase their brand equity and offer the market differential value that will stimulate customer loyalty. From this perspective, it is crucial for retailers to investigate the relationship between the store and their own brands. This study proposes two theoretical models showing the mechanism whereby store image helps increase the equity of a specific type of distributor brand (the store brand). The approach used in this analysis is based, on the one hand, on defining brand equity through its components, using the model in Aaker (1991), and on the other, on including (social and strategic) corporate dimensions in measuring store image. The empirical research made in the hypermarket sector in the Basque province of Gipuzkoa backs the majority of the proposed hypotheses. The results show that store image can be used by retailers to influence all components of store brand equity, essentially through its commercial and strategic dimension. This research is intended to address the clear lack of research on store brand equity. 相似文献

We show that the optimal advertising strategy under the Generalized Bass Model (GBM) involves beginning at an extremely low level (the lower the better) and then increasing spending throughout the planning period. This strategy remains optimal in the presence of decreasing prices that affect both margins and diffusion speed. We provide a simple explanation for why this happens. We further show that the intuitively appealing patterns of continuous decrease or increase-then-decrease (both with an uptick towards the end) identified in earlier research are also possible as optimal dynamic advertising paths under the GBM structure, but only if the advertising at launch is constrained to be higher than a particular threshold, which we identify. The constraint necessary to generate intuitively appealing strategies lowers overall profits. Therefore, the GBM generates advertising policy recommendations that most marketers would deem odd. This casts doubt on the value of the GBM for normative purposes. Other existing diffusion models are preferred when seeking normative guidance on optimal dynamic advertising policies for new products subject to word of mouth. 相似文献

近年来,铁矿石价格的持续飙升给我国经济造成了巨大的影响.本文采用国家信息中心与澳大利亚MONASH大学共同开发的SICGE模型对进口铁矿石涨价的影响进行了模拟.结果显示,与2010年基准情景相比,铁矿石价格上涨90%对我国总体经济影响很小(-0.37%).从物价水平角度来看,与现有文献的结论有很大的不同,铁矿石价格上涨... 相似文献
