The proliferation of smartphones and other mobile devices has led to numerous companies investing significant resources in developing mobile applications, in every imaginable domain. As apps proliferate, understanding the impact of app adoption on key outcomes of interest and linking this understanding to the the underlying mechanisms that drive these results is imperative. In this paper, we explore the changes in user behavior induced by adoption of a mobile application, in terms of engagement and matching outcomes in the online dating context. We also identify three mechanisms that are somewhat unique to the mobile environment, but are hitherto unestablished in the literature, that drive this shift in behavior – ubiquity, impulsivity and disinhibition. Our main identification strategy uses propensity score matching combined with difference-in-differences, coupled with a rigorous falsification test to confirm the validity of our identification strategy. Our results demonstrate that mobile app adoption induces users to become more socially engaged as measured by key engagement metrics such as visiting significantly more profiles, sending significantly more messages, and importantly, achieving more matches. We also discover various mechanisms facilitating this increased engagement: ubiquity of mobile use – users login more, and login across wider range of hours in the day. We find that men act more impulsively, in that they are less likely to check the profile of a user who messaged them before replying to them. This effect is not visible for women who continue to be deliberate in their checking before replying even after adoption of the mobile app. Finally, we find that both men and women exhibit disinhibition, in that users initiate actions to a more diverse set of potential partners than they did before on dimensions of race, education and height.

Hypertension has not been well studied by operations researchers from a clinical decision support perspective. Moreover, little personalized (i.e. patient-centric) guidance is available regarding the number and combination of antihypertensive medications. To fill this gap, we develop a Markov Decision Process (MDP) to characterize the optimal sequence (and combination) of antihypertensive medications under the standard medication dose. Our model is patient-centric as it takes into account a set of relevant patient characteristics such as age, gender, blood pressure level, smoking habits, diabetes status, and cholesterol level. Based on a set of intuitive assumptions, we prove that our model yields a series of structured optimal policies. Having calibrated our model based on real data and medical literature, we analyze these optimal policies and discuss their insights to the real practice. We also compare the benefits, in terms of quality adjusted life expectancy, QALE, obtained from our results with those obtained from British Hypertension Society (BHS) guideline.

This paper presents an analytical framework of the product take back legislation in the context of product reuse. We characterize existing and proposed forms of E-waste legislation and compare their environmental and economic performance. Using stylized models, we analyze an OEM’s decision about new and remanufactured product quantity in response to the legislative mechanism. We focus on the 2012 waste electrical and electronic equipment directive in Europe, where the policy-makers intended to create additional incentives for the product reuse. Through a comparison to the original 2002 version of the directive, we find that these incentives translate into improved environmental outcomes only for a limited set of products. We also study a proposed policy that advocates a separate target for the product reuse. Our analysis reveals that from an environmental standpoint, the recast version is always dominated either by the original policy or by the one that advocates a separate target for the product reuse. We show that the benefits of a separate reuse target scheme can be fully replicated with the aid of fiscal levers. Our main message is that there cannot be a single best environmental policy that is suitable for all products. Therefore, the consideration of product attributes is essential in identification of the most appropriate policy tool. This can be done either by the implementation of different policies on each product category or by implementation of product based target levels.

Management Science is a scholarly journal that publishes scientific research on the practice of management. Within our scope are all aspects of management related to strategy, entrepreneurship, innovation, information technology, and organizations as well as all functional areas of business, such as accounting, finance, marketing, and operations. We include studies on organizational, managerial, and individual decision making, from both normative and descriptive perspectives.

We examine the role of the chief marketing officer (CMO) in corporate voluntary disclosure of future revenues. Using a sample of S&P 1500 firms for the period from 2003 to 2011, we find that the presence of an influential CMO in top management is positively associated with the likelihood of a firm's issuing a management revenue forecast. We also find that firms with an influential CMO provide more accurate revenue forecasts than other firms. These findings extend to long-window change analyses and are robust to the use of a propensity-score matched-pair approach. Overall, the results are consistent with the notion that CMO influence in top management appears to play an important role in voluntary revenue disclosures.

Building on our review of the strategy process and practice research, we identify three ways to see the relationships between the two research traditions: complementary, critical, and combinatory views. We adopt in this special issue the combinatory view, in which activities and processes are seen as closely intertwined aspects of the same phenomena. It is this view that we argue offers both strategy practice and strategy process scholars some of the greatest opportunities for joint research going forward. We develop a combinatory framework for understanding strategy processes and practices (SAPP) and based on that call for more research on (a) temporality, (b) actors and agency, (c) cognition and emotionality, (d) materiality and tools, (e) structures and systems, and (f) language and meaning.
