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.
Collective Information System Use: A Typological Theory
Authors: Bogdan Negoita, Liette Lapointe and Suzanne Rivard
Publication: MIS Quarterly, Vol. 42 Issue 4, 1281-1301, 2018
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.

A Primal-Dual Lifting Scheme for Two-Stage Robust Optimization
Authors: Angelos Georghiou, Angelos Tsoukalas, Wolfram Wiesemann
Publication: Operations Research, Forthcoming
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.
