We study how price dispersion varies with product characteristics at a popular online price comparison site – Shopper.com. Our primary finding suggests that price dispersion in online markets varies with product characteristics and firm behavior. We also find evidence that the level of dispersion varies with the percent of firms listing price information in multiple categories. When the percent of firms listing prices in multiple categories is relatively high (low), price dispersion is low (high).

In recent years, the field of comparative and international education (CIE) has experienced an outburst of self-reflective papers wherein comparativists study the nature of the field and map its content. This study contributes to this trend by drawing attention to a previously unstudied aspect of CIE: its purpose. Using Arnove’s dimensions as a starting point to create five new purpose categories, four prominent CIE journals are surveyed to test whether the pragmatic history of CIE is evident in its current body of research. In this process, a complete and clear genetic mapping of the journals is created, which explores their similarities and differences, as well as the changes in their content over time. Findings indicate that the pragmatic purpose of CIE dominates, though it is primarily emancipatory and transformative in its prescription. Furthermore, articles rooted in specific situational contexts were more prominent than expected considering the comparative and international nature of the field.

The authors explore how entrepreneurs with limited resources legitimated (or failed to legitimate) a new organizational category in different jurisdictions in Canada despite severe resistance. The authors identify three meso-level domains of institutional action (public, administrative, and legal), where actors intervene to change their macro-institutional environment. The findings suggest that these domains mediate the relationship between micro-level agency and macro-level institutions. The authors describe how macro-level consensus about the category legitimacy emerges through a competition between judgments embedded in different discourses and how a particular discourse attains validity, forcing other actors to change their initial unfavorable legitimacy judgments and recognize the category’s legitimacy.

When decision makers encounter new assurance services that can be customized for individual clients, they must include them in their pre-existing categorization of assurance, a cognitive task known as postclassification. This paper draws upon three literatures (classification research in accounting, theory of assurance, and cognitive psychology) in order to suggest how this task might be modeled and studied empirically, using the example of SysTrust™. The role of a necessary condition for successful postclassification called the category use effect (Ross, 2000), in which decision makers are reminded of pre-existing categories when they learn to use new categories, is explained.

Academic libraries have endured rapid change in the past two decades that has had repercussions on how they manage their organization and deliver library services. Skyrocketing costs, especially for journals, explosive growth in new technologies, fiscal exigencies caused by a tightening of public financing of most academic institutions, demands for greater accountability, and the onslaught of electronic delivery of networked information, are just some of the major obstacles libraries are encountering (Lubans, 1996; Riggs, 1993; Shaughnessy, 1987). Customers of academic libraries are increasingly less satisfied because of limited resources and the difficulties they encounter in accessing printed material in a traditional library facility (Doughtery, 1992). The emergence of textual materials in electronic form has added a new dimension to this discontent. While such resources have the potential for meeting the information needs more dynamically, the costs for information have been exorbitant, particularly since full electronic texts have not been sufficient in coverage to supplant printed resources (Tenopir, 1993). These phenomena require academic libraries to use a more integrated and flexible approach to problem solving (Gapen, Hampton & Schmitt, 1993).

This paper reports on part of a dissertation project on the relationships between learning methods and students’ information behavior in Finland. In this qualitative study, information behavior is studied in the contexts of a problem-based learning curriculum and a traditional curriculum. In 1998, 16 theme interviews were conducted at the Tampere University Medical School, which applied the problem-based learning curriculum and 15 interviews at the Turku University Medical School, in which the traditional curriculum with an early patient contact program was implemented. The focus of this paper is on the concept of information literacy as a part of the students’ information behavior and its relationships with students’ conceptions of learning. The findings indicate that students’ information literacy is developed, on the one hand, through active use of information and sources in connection with real information needs, and, on the other hand, through an educational context which offers opportunities to get different viewpoints on issues. Following the same tendency, the more developed conceptions of learning were mostly held by the students belonging to the problem-based group with simple or developed skills in information literacy, although there were exceptions from this pattern.

At different points in time, energy harnessed from nuclear technology for commercial purposes has been qualified as atoms for peace, too cheap to meter, unsafe, sustainable, and emission free. We explore how these associations – between nuclear technology (a category used in a descriptive way) and qualities such as emission free (a category used in an evaluative way) – are materially anchored, institutionally performed, socially relevant, and entrepreneurially negotiated. By considering all these factors, our analysis shows that it is possible to understand how and why categories and their meanings continue to change over time. We flesh out the implications of these observations and suggest avenues for future research.

Research on cultural entrepreneurship has explored the role of language in making and giving sense to novel ventures and market categories and in legitimating them. We analyze how an emerging de novo market category, quantum computing, is constructed through the use of analogies and metaphors. Through a multimodal analysis of interview and newspaper data, we find that in addition to using analogies and metaphors to highlight familiarity, actors also use such tropes to expound the weirdness of the new category, thus marking it as profoundly different and novel. Such tropes have a dual function; they draw the boundaries between science and laypeople but also arouse awe and curiosity among the audiences. Our study thus casts light on the cultural work during de novo category emergence.

A number of scholars have called our attention to the need to consider the social significance of demographic categories when evaluating the association between a team's composition and its performance. Implicit in the call is the idea that the association between a team's composition and its performance is more predictable when the demographic categories that define the team's composition are more significant. How to define the social significance of a demographic category is unclear. One approach is to define the importance of a demographic category in terms of interpersonal attraction. Important demographic categories generate more positive affect between category members. Alternatively, one could define the social significance of a demographic category in the context of task-related processes and activities. A demographic category is significant if it affects the activities that are more likely to be assigned to a team member (i.e., an individual's work-set). I maintain there is much to gain by adopting a role-based approach to the question. An attraction-based approach is a subset of a role-based approach. Moreover, an empirical analysis of the association between demographic categories and job categories would allow us to uncover how categorical people are in their thinking and therefore how socially significant different demographic categories are at work. When combined with a team's demographic composition and the activities that a team must accomplish, the empirical results would move us one step closer to predicting a team's success rate a priori.

This article seeks to identify the type of producers most likely to deviate from category-based expectations in the pursuit of profit. I describe circumstances under which a category’s core members are, paradoxically, more likely (than its peripheral members) to deviate. This phenomenon reflects market participants’ default expectations about core members and the resulting bias in information-search processes. I offer empirical evidence of Champagne producers getting involved in “buyer’s own brands” (BOB), a behavior that is not directly observed yet deviates considerably from grape suppliers’ category-based expectations. The econometric analysis leverages an exogenous shock that increased the scrutiny of BOB by grape suppliers. I find that before the shock, BOB products were more likely to be supplied by “traditional” houses – which grape suppliers view as core industry members and hence as being above suspicion in that regard. I discuss the implications of these results for prior work in this area as well as the article’s contribution to extant literature.
