This research examines four frequently used centrality indices — degree, closeness, betweenness, and eigenvectors — to understand the extent to which their clear theoretical distinctions are reflected in differences in empirical performance. Even for stylized networks in which one centrality...

Consumer judgment often is based on incomplete or limited knowledge of the relevant attributes. Three experiments were performed to investigate why these judgments are often insensitive to set size and why evaluations based on limited information tend to be stronger (more extreme and confident)...

Consumers often rely heavily on price as a predictor of quality and typically overestimate the strength of this relation. Furthermore, the inferences of quality they make on the basis of price can influence their actual purchase decisions. Selective hypothesis testing appears to underlie the...

[enter Abstract Body]This research investigates the effects of the amount of information presented, information organization, and concern about closure on selective information processing and on the degree to which consumers use price as a basis for inferring quality. Consumers are found to be...

When judging an object described by limited evidence, people often make judgments based on the evaluative implications of what is known and fail to adjust for what is unknown. Consequently, people tend to form extreme and confident judgments of an object even when little information is provided....

We consider the problem of predicting sales of new and existing products using both numeric and textual data contained in consumer reviews. Many extant approaches require considerable manual pre-processing of the textual data, making the methods prohibitively expensive to implement and difficult...
