A comparison of first price multi-object auctions

We compare simultaneous multi-object English-type ascending price auctions with first price sealed bid auctions in private values environments with multi-object demands. Special attention is paid to the effect of closing rules on ascending auctions’ outcomes. We find that simultaneous ascending auctions with the soft closing rule are the most efficient, while the sealed bid auctions generate the highest revenue. Ascending auctions with the hard closing rule display a significant amount of late bidding, resulting in the lowest among the three institutions revenue and efficiency.

Person–place congruency in the Internet Banking context

This study proposes and empirically validates a model that incorporates the interaction effects of consumer's shopping orientation (utilitarian/recreational) and attitudes towards the online store atmospheric qualities (information related cues, navigation cues, aesthetic cues) on online shopping behavior. The use of an underutilized technique for detecting interaction effects unveils the superiority of interaction effects over direct effects in explaining online shopping behavior. Results reveal significant interaction effects during the information search stage but not during the purchase stage. Furthermore, the interaction effects were significant only for utilitarian shoppers but not for the recreational ones. The results signify the distinctive nature of online shopping compared to the offline one, and the need for retailers to distinguish online and offline store atmosphere management.     

Revisiting faultline conceptualization: measuring faultline strength and distance

The purpose of this research is to develop a conceptually and methodologically sound measure of group faultlines (demographic alignment of members along multiple attributes within a group). This measure takes into account the concept of faultline strength (the extent of a demographic alignment across members within a group) and, thus far neglected in past work, the concept of faultline distance. This faultline distance measure reflects how far apart the emerging subgroups are on demographic characteristics. This new, more elaborate conceptualization of faultlines is validated by presenting a number of hypothetical examples that demonstrate the distinct properties of faultline measures. We also validate our measures by empirically examining the relationships between faultline strength and distance, and active, or perceived, faultlines.
