Lynn Wu is an assistant professor at the Wharton School. She is interested in studying how emerging information technologies, such as artificial intelligence, big data analytics, and enterprise social media, impact innovation, business strategy, and productivity in organizations. Specifically, her work follows three streams. In the first stream, she examines the role of newer wave of technology advances in data analytics and artificial intelligence, affect firm innovation, business strategy, labor demand, and productivity for both large firms and startups. In her second stream, she studies enterprise social media and information derived from online platforms affect individuals’ work performance, long-term career trajectories, and work-related biases. In her third stream of research, Lynn leverages fine-grained nanodata available through online digital traces to predict economic indicators such as real estate trends, labor trends and product adoption.
Lynn has published articles in economics, management and computer science. Her work has been featured by the Wall Street Journal, Businessweek, New York Times, and The Economist.
Lynn received her undergraduate degrees from MIT (Finance and Computer Science), her master’s degree from MIT (Computer Science) and her Ph.D. from MIT Sloan School of Management (Management Science).
Lynn Wu and Gerald Kane (2019), Network-biased Technical Change: How Information Management Tools Overcome Some Biases but Exacerbate Others, Organization Science, Conditionally Accepted.
Abstract: Organizations have long sought to improve employee performance by managing knowledge more effectively. In this paper, we test whether the adoption of digital tools for expertise search and access within an organization, often referred to as a support to an organization’s transactive memory system (TMS), improves employee performance. Using three years of data from more than 1,000 employees at a large professional services firm, we find that adopting an expertise search tool improves employee performance on financial dimensions, which results from improvements in network connections and information diversity. However, it does not affect all employees equally. We find that two types of employees appear to benefit from adoption more than others. First, traditionally information-disadvantaged employees (junior employees and women) appear to gain more from the adoption of Digital TMS tools (DTMS) because the tool overcomes the institutional barriers to resource access that these employees face in searching for knowledge. Second, employees with greater structural capital at the time of adoption also benefit more, because the tool eliminates natural networking barriers present in traditional offline interpersonal networks, allowing these employees to network more strategically. We also find that communication volume increases more for junior employees and women and increases it less for people with strong social networks, suggesting the mechanisms that benefit people with strong networks differ from those for women and junior employees, a finding consistent with our theoretical mechanisms. Taken together, an important implication of these findings is that implementing and adopting expert search tools for TMS has the potential to shift organizational sources of power and influence away from demographic-based characteristics and toward network-based ones—a characteristic we call “network-biased technical change.”
Jay Dixon, bryan hong, Lynn Wu (Under Revision), The Employment Consequences of Robots: Firm-Level Evidence.
Abstract: As a new general-purpose technology, robots have the potential to radically transform industries and affect employment. Preliminary empirical studies using industry and geographic region-level data have shown that robots differ from prior general-purpose technologies and predict substantial negative effects on employment. Using novel firm-level data, we show that investments in robotics are associated with increased employee turnover, but also an increase in total employment within the firm. Examining changes in labor composition, we find that manager headcount has decreased but non-managerial employee headcount has increased, suggesting that robots displace managerial work that in prior waves of technology adoption was considered more difficult to replace. However, we also find that firms are more likely to hire managers from outside the firm and invest in additional training, suggesting that firms require different employee skills as the nature of work changes with robot investment. We also provide additional evidence that robot investments are not generally motivated by the desire to reduce labor costs but are instead related to an increased focus on improving product and service quality. With respect to changes in the way work is organized within the firm, we find that robot adoption predicts organizational changes in ways that differ from prior technologies. While information technology has generally been found to decentralize decision-making authority within organizational hierarchies, we find that robots can either centralize or decentralize decision-making, depending on the task. Overall, our results suggest that the impact of robots on employment is more nuanced than prior studies have shown.
C. Eesley and Lynn Wu (2019), For Startups, Adaptability and Mentor Network Diversity can be Pivotal: Evidence from a Randomized Experiment on a MOOC Platform, MISQ, Forthcoming.
Abstract: Entrepreneurs leading digital ventures are often advised to be adaptable. However, research on how to pursue adaptable strategies and whether such strategies improve short- or long-term digital venture outcomes is sparse. By utilizing the ability to control content presentation and to measure outcomes through a course using a MOOC platform, we can introduce exogenous variation in strategies and mentorship characteristics, and link these attributes to venture outcomes over time. Contrary to expectations, we find that minimizing adaptability by adhering to a strong, persistent vision often results in better short-term outcomes as measured by quality of the pitch in digital startups. It also however results in worse long-term outcomes as measured by revenue, funding, and pivoting to a new venture. A more adaptable approach, when combined with a mentor who can facilitate this strategy by providing access to a structurally diverse social network, can offer the best combination of short- and long-run outcomes. The results suggest that guidance on mentor selection—especially selecting for the mentor’s social network attributes—is important over time for reaping the benefits of an adaptable strategy, particularly for digital ventures at their early-stage.
Abstract: Data analytics technology can accelerate the innovation process by enabling existing knowledge to be identified, accessed, combined and deployed to address new problem domains. However, like prior advances in information technology, the ability of firms to exploit these opportunities depends on a variety of complementary human capital and organizational capabilities. We focus on whether analytics is more valuable in firms where innovation within a firm has decentralized groups of inventors or centralized ones. Our analysis draws on prior work measuring firm analytics capability using detailed employee-level data and matches these data to metrics on intra-firm inventor networks that reveal whether a firm’s innovation structure is centralized or decentralized. In a panel of 1,864 publicly-traded firms from the years 1988 to 2013, we find that firms with a decentralized innovation structure have a greater demand for analytics skills and receive greater productivity benefits from their analytics capabilities, consistent with a complementarity between analytics and decentralized innovation. We also find that analytics helps decentralized structures to create new combinations and reuse of existing technologies, consistent with the ability of analytics to link knowledge across diverse domains and to integrate external knowledge into the firm. Furthermore, the effect primarily comes from the analytics capabilities of the non-inventor employees as opposed to inventors themselves. These results show that the benefit of analytics on innovation depends on existing organizational structures. Similar to the IT-productivity paradox, these results can help explain a contemporary analytics-innovation paradox—the apparent slowdown in innovation despite the recent increase in analytics investments.
Xitong Li and Lynn Wu (2018), Herding and Social-Network Word-of-Mouth: Evidence from Groupon, MISQ, 42 (4).
Abstract: Modern online retailing practices provide consumers with new types of real-time information that potentially increase demand. In particular, showing past product sales information can reduce uncertainty about product quality, leading consumers to herd. This effect could be particularly strong for experience goods due to their inherent high uncertainty about product quality. Social media word-of-mouth (WOM) can increase product awareness as product information spreads via social media, not only increasing demand directly, but also amplifying existing quality signals such as past sales. This study examines the mechanisms behind the strategy of facilitating herding and the strategy of integrating social media platforms to understand the potential complementarities between the two strategies. We conduct empirical analysis using data from Groupon.com which sells goods in a fast cycle format of “daily deals.” We find that facilitating herding and integrating social media platforms are complements in generating sales, supporting that it is beneficial to combine the two strategies together on social media-driven platforms. Furthermore, we find that herding is more salient for experience goods, consistent with our hypothesized mechanisms, while the effect social media WOM does not differ between experience goods and search goods.
Lynn Wu, Lorin M. Hitt, Bowen Lou (2018), Data Analytics Skills, Innovation and Firm Productivity, Management Science, Forthcoming.
Abstract: We examine the relationship between data analytics capabilities and innovation using detailed firm-level data. To measure innovation, we first utilize a survey to capture two types of innovation practices, process improvement and new technology development for 331 firms. We then use patent data to further analyze new technology development for a broader sample of more than 2,000 publicly-traded firms. We find that data analytics capabilities are more likely to be present and are more valuable in firms that are oriented around process improvement and that create new technologies by combining a diverse set of existing technologies than they are in firms that are focused on generating entirely new technologies. These results are consistent with the theory that data analytics are complementary to certain types of innovation because they enable firms to expand the search space of existing knowledge to combine into new technologies, as well as prior theoretical arguments that data analytics support incremental process improvements. Data analytics appear less effective for developing entirely new technologies or creating combinations involving a few areas of knowledge, innovative approaches where there is either limited data or limited value in integrating diverse knowledge. Overall, our results suggest firms that have historically focused in specific types of innovation—process innovation and innovation by diverse recombination—may become the leading investors in data analytics and receive the most benefits from it.

bryan hong and Lynn Wu (Under Revision), Information Technology, Organizational Delayering, and Firm Productivity: Evidence from Canadian Microdata.
Abstract: Using novel data covering a sample of businesses representative of the Canadian economy, we show that information technology (IT) investment has led to the removal of managerial layers within organizational hierarchies, and that IT investments and organizational delayering are complementary in improving firm productivity. We find evidence that IT-based delayering has affected the employment of managers but not non-managerial employees, and leads to increased automation and process innovations. As a result, IT has replaced certain routine managerial functions within the firm. However, by analyzing detailed decision-making authority over a wide range of tasks, we find that managers remaining within the firm have also gained greater authority over a broader range of strategic activities critical to organizational performance that can complement IT investment. This phenomenon, which we consider an “IT management paradox,” is distinct from prior studies that have found that IT investments often lead to decreased decision authority for managers through centralization or decentralization.

Conducting business in a networked economy invariably involves interplay with technology. The purpose of this course is to improve understanding of technology (what it can or cannot enable) and the business drivers of technology-related decisions in firms. We will be discussing some of the new and most disruptive technologies right now to stimulate thought on new applications for commerce and new ventures, as well as their implications to the tech industry as a whole. Topics include social media, online advertising, big data, and cloud computing. The course will take a layered approach (from network infrastructure) to data infrastructure to applications infrastructure, or direct enablers of commerce) to first, understanding and then, thinking about technology enablers. Network infrastructure layers include fundamentals of wired and wireless infrastructure technologies such as protocols for networking, broadband technologies - for last (DSL, Cable etc) and other miles (advances in optical networking) and digital cellular communications. Data infrastructure layers include usage tracking technologies, search technologies and data mining. Direct application layers include personalization technologies (CRM), design technologies for content and exchanges, software renting enablers, application service provision, agents and security mechanisms. Finally some emberging technology enablers (such as bluetooth, biometrics and virtual reality) are identified and discussed.
This course is about understanding emerging technology enablers with a goal of stimulating thinking on new applications for commerce. No prerequisite or technical background is assumed. The class is self-contained (mainly lecture-based) and will culminate in a class-driven identification of novel businesses that exploit these enablers. No prerequisite or technical background is assumed. Students with little prior technical background can use the course to become more technologically informed. Those with moderate to advanced technical background may find the course a useful survey of emerging technologies. The course is recommended for students interested in careers in consulting, investement banking and venture capital in the tech sector.
