公开市场业务、公告操作与国债规模

20世纪90年代以来在西方市场经济国家兴起的公告操作方式,不仅使公开市场业务突破了对国债规模要求的限制,而且在相当程度上弥补了公开市场业务的缺陷,提高了货币政策的运行效率.鉴于我国国债规模相对较小,远远不能适应公开市场操作要求的情况,我们有必要借鉴国外的经验,积极创造条件实行不依赖于国债规模且有效的货币政策操作模式即公告操作.

When eWOM becomes cynical

Nowadays, it is common practice for corporations to communicate with consumers through social network sites (SNSs), such as YouTube, which allow consumers to share and comment on companies’ sponsored videos communicating their marketing campaigns. The authors conducted a qualitative assessment of posts written on the official YouTube site of Coca Cola, where the brand asks consumers to join in a brigade against obesity. Results extend the current knowledge about consumers’ negative electronic word of mouth (eWOM), identifying three forms of cynical consumer communication styles in response to corporate campaigns on SNSs: skeptical, passive‐aggressive and warrior eWOM. Managerial implications, limitations and some avenues for future research are indicated.

Electronic word-of-mouth communities from the perspective of social network analysis

This paper is focused on the identification of influencers that can have an important impact over the decision-making of other users. For this purpose, a popular electronic word-of-mouth community like Ciao.com has been modelled as a social network. Using social network analysis techniques, the existence of influencers is justified by the power law distribution of user participation, and then they are identified using their topological features within the social network. The obtained results reveal that influencers are not determined by the number of performed reviews, but by the variety or scope of their performed reviews and their central position in the consumer network. The main contribution of this research is the identification of influencers based on the participation features of community users. As a difference to other studies, results are not based on surveys or opinions, but on the trace users leave when they post opinions, comments or scores.
