THE FORMATION MECHANISM OF CONSUMER PRODUCT ATTITUDE IN ONLINE INFOMEDIARY

Abstract The online infomediary, playing an important role in e-commerce, provides more unbiased and refined product information than usual advertisement provided by online retailers. Interestingly, depending on its capability, the quality of product information is likely to differ. Also, given the fact that it enables consumers to grasp market price dispersion of products, the context of online infomediary is a good context to investigating the effects of price dispersion. Despite the several previous endeavors that studied the existence of price dispersion in e-commerce, the reaction of consumers to price dispersion have not been investigated in a comprehensive way. This paper uses the elaboration likelihood model to explain how the level of involvement with a product moderates the impact of price dispersion and product information quality on consumer product attitude in online infomediary. A study conducted to test hypotheses has largely confirmed our expectations: (1) Interaction effects between involvement and price dispersion on consumer product attitude is significantly confirmed. (2) For low-involvement consumers, price dispersion of a product positively affects consumer product attitude, and for high-involvement consumers, it produces a negative effect, (3) Low-involvement consumers are affected by price dispersion rather than the quality of product information, but high-involvement consumers are mainly affected by price dispersion when the quality of the product information is low. These findings have implications for online infomediaries in terms of how to manage their users

Smart Retail, Replaces All? Some? : Different Influence of Amazon Go to Local Restaurant Industry.

Amazon Go, the pioneering smart retailer, has been opening physical stores in metropolitan areas of the USA, and seductively distracted customers from adjacent competitors by provisioning quick-and-easy service. This study focuses on how the appearance of the smart retailer affects adjacent competing businesses. We constructed a panel dataset with various features and reviews of restaurants from Yelp.com, and created two dummies, , one if the restaurant is in a certain radius of a smart retailer and zero outside, and , one after the introduction and zero before. By using Difference-in-Difference estimation, we find that (1) negative impacts on the adjacent restaurants after Amazon Go compared to non-adjacent and before the appearance, and (2) less negative impact on adjacent fine-dining restaurants than fast-food restaurants. After Amazon Go, customers’ sentiments about the adjacent restaurants have changed more negatively. This paper may provide businesses with useful implications for their strategies

An empirical analysis of maturity model to assess information systems success: a firm-level perspective

This research investigates the relationship between IS investment and IS success and the moderating effects of IS maturity. We find the moderating role of IS maturity between IS investment and IS success with a contingency perspective. As administering a group survey of about 300 business executives across multiple industries, the results of this study indicate that IS investment is a critical antecedent of IS success, and IS maturity has a positive moderating effect on this relationship. The implication of the findings implies that global companies should consider the maturity of their IS management: as a crucial factor in maximising the effectiveness of IS investment

A pyrene–poly(acrylic acid)–polyrotaxane supramolecular binder network for high-performance silicon negative electrodes

Although being incorporated in commercial lithium‐ion batteries for a while, the weight portion of silicon monoxide (SiOx, x ≈ 1) is only less than 10 wt% due to the insufficient cycle life. Along this line, polymeric binders that can assist in maintaining the mechanical integrity and interfacial stability of SiOx electrodes are desired to realize higher contents of SiOx. Herein, a pyrene–poly(acrylic acid) (PAA)– polyrotaxane (PR) supramolecular network is reported as a polymeric binder for SiOx with 100 wt%. The noncovalent functionalization of a carbon coating layer on the SiOx is achieved by using a hydroxylated pyrene derivative via the π–π stacking interaction, which simultaneously enables hydrogen bonding interactions with the PR– PAA network through its hydroxyl moiety. Moreover, the PR's ring sliding while being crosslinked to PAA endows a high elasticity to the entire polymer network, effectively buffering the volume expansion of SiOx and largely mitigating the electrode swelling. Based on these extraordinary physicochemical properties of the pyrene–PAA–PR supramolecular binder, the robust cycling of SiOx electrodes is demonstrated at commercial levels of areal loading in both half‐cell and full‐cell configurations
