摘要：In using the generalized second-price (GSP) auction to sell advertising slots, a search engine faces several challenges. Advertisers do not truthfully bid their valuations, and the valuations are uncertain. Furthermore, advertisers are budget constrained. In this paper we analyze a stylized model of the first-page bid estimate (FPBE) mechanism first developed by Google and demonstrate its advantages in dealing with these challenges. We show why and when the FPBE mechanism yields higher profits...

摘要：This paper studies the supply management of a primary input, where this input gives rise to multiple products in fixed proportions. My objective is twofold. First, I study fixed proportions technology under demand uncertainty in comparison with the flexible and dedicated technologies. I show that fixed proportions technology has a cost-pooling value over dedicated technology, which is larger than the capacity-pooling value of flexible technology over dedicated technology. I identify the critic...

摘要：Examining changes in two different retail formats, we show that consumers alter their purchases depending on the retail environment. In both settings, the change in behavior coincides with a reduction in the interpersonal interaction required to complete a transaction. As such, we contend that the format changes reduced a social friction that would otherwise inhibit consumers due to an implicit cost associated with ordering certain items in social settings.

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：In this paper, we investigate whether and how the presence of remanufactured products and the identity of the remanufacturer influence the perceived value of new products through a series of behavioral experiments. Our results demonstrate that the presence of products remanufactured and sold by the original equipment manufacturer (OEM) can reduce the perceived value of new products by up to 8%. However, the presence of thirdparty-remanufactured products can increase the perceived value of new ...

摘要：This study examines how cognitive changes associated with aging impact the financial decision-making capability of older Americans. We find that a decrease in cognition is associated with a decrease in financial literacy. Decreases in episodic memory and visuospatial ability are associated with a decrease in numeracy, and a decrease in semantic memory is associated with a decrease in financial knowledge. A decrease in cognition also predicts a drop in self-confidence in general, but importantl...

摘要：Online consumers are uncertain about subjective product quality (e.g., fit and feel of clothing and texture of materials) because of the absence of experiential information. In this paper, we examine the dynamic change of the products purchased online over time in the presence of this type of uncertainty. Using individual-level transaction data, we find that consumers purchase products with a high degree of product uncertainty as their online shopping experiences help them better estimate prod...

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：The dynamic assignment of patients to exam days in order to manage daily variations in demand and capacity is a long-standing open research area in appointment scheduling. In particular, the dynamic assignment of advance appointments has been considered to be especially challenging because of its high dimensionality. We consider a canonical model of dynamic advance scheduling with two patient classes: an urgent demand class, which must be served on the day of arrival, and a regular demand clas...
