Abstract:
Although significant research has examined the effect of enterprise information systems on the behavior and careers of employees, the majority of this work has been devoted to the study of blue- and gray-collar workers, with little attention paid to the transformative effect information technology may have on high-status professionals. In this paper, we begin to bridge this gap by examining how highly skilled professionals react to the increasing presence of enterprise systems within their organizations. Specifically, we investigate how the implementation of enterprise systems-in the form of electronic health records-affects the decision of physicians to continue practicing at their current hospital. Results suggest that when enterprise systems create complementarities for professionals, their duration of practice at the organization increases significantly. However, when technologies are disruptive and force professionals to alter their routines, there is a pronounced exodus from the organization. Interestingly, these effects are strongly moderated by individual and organizational characteristics, such as the degree of firm-specific human capital, local competition, and the prevalence of past disruptions, but are not associated with accelerated retirement or the strategic poaching of talent by competing organizations.

Abstract:
In this review essay, we assess the shale revolution through the lens of management theory and practice. First, we contend that fracking in America is a textbook example of “good” management. Nonetheless, as we subsequently document, fracking’s influence extends beyond immediate impacts in many social, environmental, and economic spheres, often with negative repercussions. Although management scholars have remained on the sidelines, academics from a variety of other disciplines have actively participated in this debate. We identify several topics where management scholars seem positioned to contribute well-informed opinions on fracking. We close the essay by posing suggestions for what such public engagement might look like. First, we consider the kinds of problems that might lend themselves to public debate. Second, we tackle questions related to the ground rules for such debates, in terms of potential norms. Finally, we differentiate the kinds of public debates we have in mind from other forms of academic relevance. Essentially, we advocate for “going public” as a complement to rigorous and evidence-based academic research.

This article studies the impact of shopping at the warehouse club format on households' packaged food-for-home purchases. In addition to low prices, this format has several unique characteristics that can influence packaged food purchases. The empirical analysis uses a combination of households' longitudinal grocery purchase information, rich survey data, and detailed item-level nutrition information. After accounting for selection on observables and unobservables, the authors find a substantial increase in the total quantity (servings per capita) of purchases attributable to shopping at this format. Because there is no effect on quality of purchases, this translates into a substantial increase in calories, sugar, and saturated fat per capita. The increase comes primarily from storable and impulse foods and it is drawn equally from foods that have positive and negative health halos. The results have important implications for how marketers can create win–win opportunities for themselves and for consumers.

Abstract:
As the nature of information systems (IS) has evolved from primarily standalone, to enterprise, and distributed applications, the need for a better understanding of collective IS use has become a research and practical necessity. In view of contributing to this understanding, we conceptually define collective IS use as a unit level construct, rooted in instances of individual-level IS use within the context of a common work process. Its emergence from the individual to the unit level is shaped by different configurations of task, user, and system interdependence between instances of individual-level IS use. On the basis of this definition, we propose a typology of collective IS use that comprises four ideal types, namely siloed use, processual use, coalesced use, and networked use. For each ideal type, we theorize on the emergence process from the individual to the unit level and we consider the measurement implications for each.

Abstract:
Two-stage robust optimization problems, in which decisions are taken both in anticipation of and in response to the observation of an unknown parameter vector from within an uncertainty set, are notoriously challenging. In this paper, we develop convergent hierarchies of primal (conservative) and dual (progressive) bounds for these problems that trade off the competing goals of tractability and optimality: While the coarsest bounds recover a tractable but suboptimal affine decision rule approximation of the two-stage robust optimization problem, the refined bounds lift extreme points of the uncertainty set until an exact but intractable extreme point reformulation of the problem is obtained. Based on these bounds, we propose a primal-dual lifting scheme for the solution of two-stage robust optimization problems that accommodates for generic polyhedral uncertainty sets, infeasible problem instances as well as the absence of a relatively complete recourse. The incumbent solutions in each step of our algorithm afford rigorous error bounds, and they can be interpreted as piecewise affine decision rules. We illustrate the performance of our algorithm on illustrative examples and on an inventory management problem.
