Abstract
In this editorial forum, we individually discuss (1) the roles and responsibilities of a senior editor (SE) as informed by our experiences, (2) key challenges to fulfilling the role of senior editor, and (3) philosophies/characteristics/ values/practices that are associated with the most effective SEs. A consensus emerges that it is the responsibility of SEs to determine the final disposition of papers submitted to their journal in light of various tradeoffs. In making these decisions, the SE must be cognizant of authors’ careers and the field’s intellectual development. We recognize the constructive element of the SE role and the importance of their offering guidance to the authors. While there was disagreement as to whether the “invisible college” or formal policies should be enacted to limit undesirable practices, suggestions emerged about how SEs could be better recognized for their contributions and SE-related policies could be enacted to improve the review process.

PAPER ONE
Stated Choice Analysis of Conditional Purchase and Information Cue Effects in Online Group Purchase

Abstract
Group-purchase institutions, a type of Internet shopping website, allows consumers to aggregate their demands for a product to gain discounts in purchase price. Modeling consumers’ bidding behavior in this institution using the economic perspective of constraint, expectation, and preference interactions, we study two group-purchase mechanisms (i.e., conditional purchase and information cue) on a buyer’s purchase choice across competing group-purchase alternatives. Using a conditional purchase mechanism, a buyer is not obliged to commit to the purchase if the best price is not met (i.e., the final offered price is greater than the best available lowest price). Through the information cue, a buyer could obtain information on the current number of orders collected. We analyzed a set of laboratory experimental data based on a group-purchase institution using the stated choice method. We find that a buyer is more likely to buy through group-purchase when a conditional purchase mechanism is provided. However, providing more information does not necessarily alleviate buyer uncertainty and inertia. The presence of information cue does induce them to choose a riskier but cheaper group-purchase option. In such cases, the choice elasticity of a risky group-purchase option is more sensitive to the information cue than to the conditional purchase mechanism.

PAPER TWO
Consumer Co-creation of Digital Culture Products: Business Threat or New Opportunity?

Abstract
New forms of implicit consumer collaborations in online communities and social networks influence demand preferences as consumers themselves increasingly participate in creating cultural products that both complements and competes with firm offerings. Although research findings on these issues vary, strong evidence from both theoretical and empirical work suggests that the increased technology affordance on the consumer side challenges the profitability of conventional producer strategies that are based on pushing product designs that serve large segments of consumers while ignoring the service of more nuanced consumer preferences. In this study, we present a market design in which producers create and sell original digital culture product and, examine the effect of consumer co-creation in the presence of consumer sharing (piracy) on market performance in terms of consumer and producer surplus and consumer choice. Using the methods of experimental economics, we find strong interaction effects between consumer sharing and co-creation, and, more specifically, we find that consumer sharing interacts with consumer-based co-creation and increases product variety and consumer surplus while reducing producer benefits from co-creation.

PAPER THREE
Designing a Requirement Mining System

Abstract
The success of information systems (IS) development strongly depends on the accuracy of the requirements gathered from users and other stakeholders. When developing a new IS, about 80 percent of these requirements are recorded in informal requirements documents (e.g., interview transcripts or discussion forums) using natural language. However, processing the resultant natural language requirements resources is inherently complex and often error prone due to ambiguity, inconsistency, and incompleteness. Thus, even highly qualified requirements engineers often struggle to process large amounts of natural language requirements resources efficiently and effectively. In this paper, we propose a design theory for requirement mining systems (RMSs) based on two design principles: (1) semi-automatic requirement mining and (2) usage of imported and retrieved knowledge. As part of an extensive design project, which led to these principles, we also implemented a prototype based on this design theory (REMINER). It supports requirements engineers in identifying and classifying requirements documented in natural language and allows us to evaluate the artifact’s viability and the conceptual soundness of our design. The results of our evaluation suggest that an RMS based on our proposed design principles can significantly improve recall while maintaining precision levels.
