Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

The nascent crowdfunding literature has highlighted the existence of a self-reinforcing pattern whereby contributions received in the early days of a campaign accelerate its success. After discussing what sustains this pattern, we maintain that the internal social capital that proponents may develop inside the crowdfunding community provides crucial assistance in igniting a self-reinforcing mechanism. Results of an econometric analysis of a sample of 669 Kickstarter projects are consistent with this view. Moreover, the effect of internal social capital on the success of a campaign is fully mediated by the capital and backers collected in the campaign's early days.

Customer loyalty or repeat purchasing is critical for the survival and success of any store. By focusing on online stores, this study investigates the moderating role of habit on the relationship between trust and repeat purchase intention. Prior research on online behavior continuance models perceives usefulness, trust, satisfaction, and perceived value as the major determinants of continued usage or loyalty, overlooking the important role of habit. We define habit in the context of online shopping as the extent to which buyers tend to shop online automatically without thinking. Building on recent research on the continued usage of IS and repeat purchasing, we develop a model suggesting that habit acts as a moderator between trust and repeat purchase intention, while familiarity, value and satisfaction are the three antecedents of habit. Data collected from 454 customers of the Yahoo!Kimo shopping mall provide strong support for the research model. The results indicate that a higher level of habit reduces the effect of trust on repeat purchase intention. The data also show that value, satisfaction, and familiarity are important to habit formation and thus relevant within the context of online repeat purchasing. The implications for theory and practice and suggestions for future research are also discussed.

Re-examining the influence of trust on online repeat purchase intention: The moderating role of habit and its antecedents

Internet-based group-buying auctions enable consumers to obtain volume discounts, but they face risk and trust issues that are not present in other e-retailing formats, which affects their adoption by consumers. Bidders experience uncertainty about the final auction price, and the risk of whether the auction will be completed. We evaluate textual comments and the number of bids made in an auction as drivers of a consumer's perceived financial and psychological risks toward the group-buying auction mechanism and trust in the auction initiator. We use an Internet-based experimental test bed for online group-buying auctions and will report on one experiment that we conducted. Our results indicate that textual comments made by the participants about sellers in past auctions and existing bids affected a consumer's perceived trust in the auction initiator and the financial risk of the mechanism. Positive textual comments and more bids appear to enhance perceived trust in the auction initiator and reduce financial risk, and other consumers are more willing to make bids as a result. Consumers continued to express concerns about the uncertainty of the final group-buying auction price though.

Consumer adoption of group-buying auctions: an experimental study

Global distribution systems (GDSs) and online travel agencies (OTAs) have been providing critical intermediation services for the air travel services industry. Their systems services have eroded the airlines' revenue by encouraging consumers to do price comparison-based purchases though, which has caused the commoditization of air travel services. The airlines have begun to adopt a la carte pricing mechanisms in their direct distribution channel, especially through their Web sites. This way, they can provide travelers with an array of information for different airline product bundles and the flexibility to customize different bundles. This mechanism design may allow airlines to decommoditize their services in the minds of consumers. We analyze two years of data from a large international airline that sold airline tickets via several different direct and indirect distribution channels. Our results suggest that demand in the a la carte channel as a whole is less price-elastic. The results for price elasticity for different market segments and bundle types across channels were not altogether consistent with our predictions though. We find that, for some branded bundles of services, price elasticity is lower in the a la carte channel, and for others it is higher. We discuss the implications for managers and the design of a la carte selling mechanisms.

By focusing on online stores, this study investigates the repeat purchase intention of experienced online buyers. Prior research on online behavior continuance models perceived usefulness, trust, satisfaction, and perceived value as the major determinants of continued adoption or loyalty, overlooking the important role of habit. Building on previous work in other disciplines, we define habit in the context of online shopping as the extent to which buyers tend to shop online automatically because of learning. Using recent work on the continued usage of IS (IS continuance) and repeat purchase, we have developed a model suggesting that repeat purchase intention is not only a consequence of trust and switching cost, but also of habit. In particular, in our research model, we propose that online shopping habit moderate the influence of trust such that its importance in determining repeat purchase intention decreases as the online shopping behavior takes on a more habitual nature. Integrating prior research on habit, IS continuance, and repeat purchase further, we suggest how antecedents of repeat purchase intention relate to drivers of habitualization. Data collected from 462 of Yahoo!Kimo shopping center’s customers provide strong support for the research model. Results indicate that higher level of habit deflated trust’s effect on repeat purchase intention. The data also show that satisfaction and familiarity are key to habit formation and thus relevant in the context of online repeat purchase.

Exploring Online Repeat Purchase Intentions: The Role of Habit

Digital intermediaries and Internet search technologies have commoditized many products, resulting in intense price competition and channel conflict. Firms use decommoditization strategies to regain control over distribution channels, as well as to implement resonance marketing and hyperdifferentiation, which allows them to improve margins through differentiation. We test two hypotheses: the decommoditization hypothesis and the resonance marketing hypothesis. We use data from an airline with a new ii¾? la carte pricing mechanism, which allows consumers to tailor airline ticket bundles to suit their individual preferences. We compare ii¾? la carte ticket pricing, whose features can be modified by the purchaser, and fixed (bundled offer) sales, which cannot be modified. We found that a significant number of travelers do use ii¾? la carte pricing, which allows the airlines to regain some control over distribution. We find that travelers customized standard bundles when it was possible for them to make ii¾? la carte ticket bookings, but mainly for low-feature standard bundles. Frequent-flyer members purchased higher-feature bundles more often when they had the opportunity. The findings support the proposed hypotheses. We discuss the implications for distribution strategy and channel conflict management.
