In marketing products with negative externalities, a schedule which specifies an order of consumer purchase decisions is crucial, since in the social network of consumers, the decision of each consumer is negatively affected by the choices of her neighbors. In this paper, we study the problems of finding a marketing schedule for two asymmetric products with negative externalites. The goals are ...

Information quality (IQ) plays a critical role in ecommerce consumers’ purchase decisions, and product-related user-generated content (PUGC) is an increasingly important source of information. Nevertheless, vendors currently do not take full advantage of PUGC since PUGC is mainly used for evaluation purposes. Integrating PUGC into earlier phases of the purchase-decision process might be promisi...

PURPOSE Although prior research suggests that economic, behavioral, and psychosocial factors influence decisions not to purchase long-term care insurance, few studies have examined the interplay among these factors in depth and from the consumer's point of view. This study was intended to further illuminate these considerations, generate hypotheses about non-purchasing decisions, and inform the...

To make informed private label (PL) strategy decisions, retailers must understand the factors influencing consumer’s brand choices. Previous PL studies have investigated grocery products, and ignored unique features of different types of own brands. We investigate attitudes towards buying a retailer-endorsed brand, or store brand (SB), in apparel retailing. Customers of a Finnish department sto...

This work focuses on the impact of sharing contexts on consumers’ decision processes and purchase-amount decisions. Four studies, using both hypothetical and real (incentive-compatible) choices, find that people regularly purchase more in sharing (vs. non-sharing) contexts. Evidence is presented suggesting that a significant portion of this effect is driven by a cognitive bias arising in sharin...

This study addresses a growing trend in how consumers obtain and use information prior to making their online purchasing decisions. Specifically, the authors investigate the relationship between online word-ofmouth (WOM, i.e., customer reviews and ratings) and sales (as measured by Amazon “ranks”) for different product categories. Using data collected from Amazon, the authors find that online W...

We explore superstitious beliefs as a basis of product performance expectations and their impact on initial purchase likelihood and subsequent satisfaction. In doing so, we demonstrate instances when superstitiondriven expectations cause consumers to make purchase decisions that run counter to economic rationality. In the first set of studies we find that Taiwanese consumers are relatively more...

In E-commerce, purchase decisions of consumers are often strongly influenced by people who consumers know and trust, and word-of-mouth (WOM) is the most important factor when consumers are making a purchase decision. Many online consumers tend to wait for the opinions of early consumers before making a purchase decision to reduce the risk of buying products. So numerous E-commerce websites prov...

Basic economic theory tells us to expect that an increase in demand should lead to an increase in price. However, previous studies have found the opposite trend in the prices of seasonal goods, such as canned soup. I propose an explanation of this phenomenon: consumers are more likely to purchase without search in low demand periods, reducing the gains of temporary price reductions, and decreas...
