This study investigates the online spectating behavior of sports fans. Due to the great mobility and low opportunity/switching costs, webcast sports fans’ spectating behaviors are distinct from those associated with traditional spectating channels such as stadium attendance or TV viewership. We explore the unique characteristics of online webcast demand in professional sports leagues by rigorously modeling all three spectating choices of sports fans. To consider the substitute relationship of the three spectating choices simultaneously, we employ a BLP (Berry–Levinsohn–Pakes)-style random coefficient model. For the analysis, we collect a comprehensive game-level dataset from the Korean Professional Baseball Organization (KBO) League fan samples from three different channels: online webcast viewership, stadium attendance, and TV viewership. We find that the demand for online webcasts is distinctive compared to that of traditional spectating channels. Notably, we find that the impact of team performance is three times stronger than that of TV viewership demand and that the impact of game quality is four times stronger than that of attendance demand. In contrast, a nonperformance variable is relatively less effective in attracting sports fans to online broadcasting. Furthermore, we find evidence of a strong retention effect of online webcast viewers. Our findings indicate that the previous spectating experience of online webcasts increases the next-time choice of sports fans for the webcast because the genuine spectating experience with distinctive webcast services (such as real-time interactive communication or various supplementary programs) can induce consumers to revisit the channel.

This paper investigates how two fundamental consumer characteristics, self-esteem (inner-self) and status seeking (outer-self), influence consumers’ purchasing behaviors of CSR (Corporate Social Responsibility) products via two mediating effects: brand image and self-enhancement. In particular, we analyze these effects in two different CSR domains: environmental and social. By doing so, we are able to verify the underlying mechanisms of how different types of consumers respond to various CSR promotions. We propose a distinctive CSR consumption model incorporating both inner-self and outer-self components. We collected data from two countries, the US and China, using two commonly used online survey platforms: Amazon M-Turk and Loop Information Technology. Using structural equation modeling, our analysis in the environmental domain revealed that both inner-self and outer-self components play a significant role in consumers’ desire to purchase CSR products. Additionally, this process is mediated by the brand image of the firm and the tendency to enhance self-value. Interestingly, we found that in the social domain, self-enhancement mediated consumer characteristics and purchasing behavior of CSR product, whereas brand image did not. This indicates that environmental CSR activities increase brand value and its impact on purchase intention, while social CSR activities do not. Additionally, we found similar patterns for both US and Chinese consumers.

In this paper, we study the online consumer review generation process by analyzing 37.12 million online reviews across nineteen product categories obtained from Amazon.com. This study revealed that the discrepancy between ratings by others and consumers’ post-purchasing evaluations significantly influenced both the valence and quantity of the reviews that consumers generated. Specifically, a negative discrepancy (‘worse than what I read’) significantly accelerates consumers to write negative reviews (19/19 categories supported), while a positive discrepancy (‘better than what I read’) accelerates consumers to write positive reviews (16/19 categories supported). This implies that others’ ratings play an important role in influencing the review generation process by consumers. More interestingly, we found that this discrepancy significantly influences consumers’ neutral review generation, which is known to amplify the effect of positive or negative reviews by affecting consumers’ search behavior or the credibility of the information. However, this effect is asymmetric. While negative discrepancies lead consumers to write more neutral reviews, positive discrepancies help reduce neutral review generation. Furthermore, our findings provide important implications for marketers who tend to generate fake reviews or selectively generate reviews favorable to their products to increase sales. Doing so may backfire on firms because negative discrepancies can accelerate the generation of objective or negative reviews.

Prior research on consumers’ web searches primarily examined the effect of web searches on product sales or the characteristics of the web searchers. Differing from prior research, we investigate the effect of marketing activities on web search volume. We selected 314 movies released in China whose box office revenues were greater than RMB 10,000. Then, we collected data points on web search volume and marketing activities from the Baidu, Sina Weibo, and Douban platforms from the 3 weeks prior to the release of each movie. Marketing activity data points were derived from three sources: news media, social network marketing, and film stars. Our data analysis of 6594 observations revealed two major findings. First, news media, social network marketing, and the effect of film stars increased the web search volumes of the films. In particular, social network marketing had the strongest impact on the web search volume. Second, the previous-day web search volume increased the present-day web search volume without marketing activities, suggesting a spillover effect. We discuss the academic contributions and managerial implications of our findings in the context of online marketing and new product launches.

This paper investigates whether online recommendation of products that exhibit corporate social responsibility (CSR) penalizes the purchase intention of non-CSR products. When consumers browse online retail stores and consider buying a particular product, online recommendation is made (e.g., “Customers who viewed this item also viewed”). This recommendation is often made between products of which attributes have a trade-off relationship (e.g., CSR vs. price). (A trade-off is where one thing increases, and another must decrease. A trade-off relationship between CSR and price suggests a pair of competing products are available: a more expensive, CSR product and an economical, non-CSR product.) We borrowed from the psychological literature of evaluability to hypothesize that when a CSR product is recommended, consumers would decrease their purchase intention of the economical product. However, when an economical product is recommended, consumers would maintain their purchase intention of the CSR product. We further hypothesized that this asymmetric effect would disappear when reinforcement information regarding the CSR is provided. Two carefully designed experiments conducted in China supported these hypotheses. Our findings contribute to the growing literature on online retailers by elucidating the psychological impact of online recommendations, which may influence manufacturers’ sales in an unexpected manner. The findings also indicate that online recommendations could be a potential source of channel conflict. While this study newly verifies the unintended CSR violation effect of online recommendations, future studies are required to expand our understanding of the CSR violation effect by investigating the effect under the trade-off relationship with other attributes of the product.
