Book excerpt: This dissertation tackles three problems in information systems: In the first essay we investigate the value of a local showroom to online competition. An increasing number of online retailers are grappling with whether to expand their operations to offline local showrooms. In this study, we quantify the value of showrooms by investigating how the presence and absence of local showrooms may impact customers’ searching and purchasing behaviors with online competitors. By using an exogenous event of a large retailer’s offline market exit and a unique data set capturing customers’ online browsing and purchasing activities before and after the event, we empirically examine the changes in online search and sales made by customers who lived within neighborhoods where showrooms closed. We question the adequacy of conventional sales-based measures and devise several search-based measures in order to better quantify the value of a showroom from the perspective of customer experience online. Using a difference-in-difference approach, we find mixed results in terms of online competitors’ sales when a neighboring showroom closes. More importantly, we observe an increase in customers’ online search intensity in the absence of local showrooms. We discuss a wide range of implications both for online and offline retailers based on our results. The second problem we analyze is the effect of worker collaboration on productivity and costs to a company. Although collaboration in the workplace is promoted as a silver bullet for increasing productivity and decreasing costs, there is little empirical evidence to show the effects of collaboration. Using a unique dataset and a field experiment we develop a framework to measure the effects of collaboration in a service delivery industry. Our results show that when collaboration is forced on employees, although productivity increases, costs also increase. Based on our conclusions we recommend management to allow employees to choose when to collaborate and when not to. On further analysis of the implementation of our recommendations, we find that productivity levels increase along with reduction in costs if employees are allowed to choose when to collaborate on tasks. Finally, we investigate how to tackle the patching schedule of custom built enterprise systems. Keeping software systems safe from hackers is one of the most important goals for system operations managers. A system that has outstanding security patches is inherently risky and managers incur costs to keep the security of such systems at an acceptable level. Alternatively, they can choose to expend resources to apply outstanding patches and increase the security state of the system and thereby reducing the costs to maintain the system. In this research we study a motivating example from the Information and Communications Technology (ICT) industry and apply a control theoretic model to solve for optimal patching periods. The optimal patching policy is shown to have a bang-bang solution which explains common approaches practiced in the industry. The results in this research are valuable to operations and maintenance managers who strive to keep enterprise software systems safe while minimizing cost.

Available in PDF, EPUB and Kindle. Book excerpt: "This thesis proposal contains three essays on information technology applications in new service settings. My first essay explores the key determinants of organizational customer service practice on social media platforms. Based on the Twitter trajectory of the airline industry, a two-stage model is proposed to estimate organizational decisions on the social media platform and social media customer service adoption. The findings suggest that a firm's decision-making is subject to the impact of peer influence and consumer pressure, and these two factors affect the social media platform and customer service adoptions differently. My second essay examines how brand-level customer complaints evolve in response to firms' service intervention on social media. The findings suggest that more service interventions lead to more customer complaints, accounting for the customer population growth and service quality. Moreover, increased complaints are primarily driven by the awareness enhancement effect. Specifically, customers learn about a firm's service availability from their friends and thus are more likely to use social media for redress seeking. My third essay investigates how telemedicine adoption affects Emergency Room care delivery. Using a large dataset covering all emergency visits of New York State from 2010 to 2014, we show that, on average, telemedicine availability in the ER significantly reduces average patients' length of stay. We further show that the adoption of telemedicine leads to a larger reduction in ER length of stay when there is a demand surge or supply shortage, which suggests that the efficiency gain is partially driven by the flexible resource allocation"--Pages ix-x.

Available in PDF, EPUB and Kindle. Book excerpt: "Although the extant literature has brought important insight to the study of individual users' reactions to information technology (IT), some limitations remain. Indeed, few studies theorize specifically about the IT artifact and incorporate these theories in the study of IT use. Also, the literature is dominated by an underlying assumption that acceptance of IT is favorable while resistance to IT is unfavorable. Another limitation is that this literature largely adopts a lean conceptualization of IT use and lacks a focus on the process of IT use (e.g. the process by which individuals make new uses of IT features). This dissertation tries to address these limitations and sheds light on important themes related to users' reactions to IT.Our first essay studies users' perceptions with regards to the modifications to an IT that occur after its implementation. Although these modifications potentially influence IT use and its impacts, they have hardly been studied from the end user's perspective. We propose and validate an artifact-focused measure of perceptions of IT modifications based on whether or not a user considers that the changes add new functionalities, improve existing functionalities, remove parts of the system, improve compatibility with other technologies and/or improve the system's speed and reliability. Our proposed measure contributes to studying users' reactions to IT, by focusing on the IT artifact; it also paves the way for further research on the very important and increasingly pervasive phenomenon of IT evolution.Our second essay proposes a framework that focuses on acceptance and resistance, and investigates the diverse set of IT- related behaviors and impacts that may be associated with them. It uncovers nuances obscured by the fact that these variables are generally considered separately, and in abstraction of the organizational context of use. With the concept of organizational intent, we show that resistance and employees' deviation from organizational IT use mandates sometimes benefit the organization. At the same time, acceptance and compliance with organizational IT use mandates may, at times, have adverse consequences. We also highlight scenarios under which employees and organizations can challenge these mandates to enable more favorable impacts. The last essay is an in-depth study of the process of using IT features in new ways, which we call 'enhanced use'. Based on interview data, we identify distinct patterns of enhanced use and the ways these patterns are influenced by task, user and system-related variables. We argue that the locus of innovation for enhanced use often differs according to the analyzability of the task and the type of system used. Also, the extent of substantive use involved in enhanced use depends largely on the complexity of the task at hand and on the IT-related knowledge used. Finally, our analysis suggests that the degree of task interdependencies and the type of system used are often associated with different patterns of adaptation for enacting enhanced use. Overall, we contribute a broad sketch of the interplay between the task-, IT- and knowledge-related variables that shape patterns of features adoption, use and extension after an IT is adopted.In sum, this dissertation enriches the research on users' reactions to IT. It focuses on important themes related to IT use including users' perceptions of IT changes, the impacts of different IT-related behaviors and the process of making new uses of IT features." --
