摘要：Online product ratings are widely available on the Internet and are known to influence prospective buyers. An emerging literature has started to look at how ratings are generated and, in particular, how they are influenced by prior ratings. We study the social influence of prior ratings and, in particular, investigate any differential impact of prior ratings by strangers (crowd) versus friends. We find evidence of both herding and differentiation behavior in crowd ratings wherein users' rating...

摘要：Branding decisions are critical for the success of new products. Prior research on branding and brand extension has primarily focused on how branding influences consumers' perceptions of product quality. However, consumers of conspicuous goods care not only about product quality but also about the profile of its users. For example, high-end consumers prefer an exclusive brand. On the other hand, low-end consumers may find a brand more attractive if high-end consumers use it. In this paper, we ...

摘要：We show that the way decision makers construct risk perceptions is systematically influenced by their level of self-control: low self-control results in greater weighting of probability and reduced weighting of consequences of negative outcomes in formulating overall threat perceptions. Seven studies demonstrate such distorted risk construction in wide-ranging risk domains. The effects hold for both chronic and manipulated levels of perceived self-control and are observed only for risks involv...

摘要：We run a series of controlled field experiments on eBay where buyers are rewarded for providing feedback. Our results provide little support for the hypothesis of buyers' rational economic behavior: the likelihood of feedback barely increases as we increase feedback rebate values; also, the speed of feedback, bid levels, and the number of bids are all insensitive to rebate values. By contrast, we find evidence consistent with reciprocal buyer behavior. Lower transaction quality leads to a high...

摘要：In this paper, we shed new light on the role of monetary policy in asset pricing by examining the case in which investors have heterogeneous expectations about future monetary policy. This case is realistic because central banks are typically less than perfectly open about their intentions. Accordingly, surveys of economists reveal that they frequently disagree in their expectations. Under heterogeneity in beliefs, investors place speculative bets against each other on the evolution of the mon...
