Lia Sheer, Ph.D.
I am an incoming Assistant Professor in Strategy (Senior Lecturer, Tenure-Track) at the Coller School of Management of Tel-Aviv University, Israel. My research focuses on organizing scientific discovery for innovation inside R&D firms. More specifically, my research examines the interplay between scientific discovery, innovation, markets for technology, knowledge spillovers, as well as their aggregated effect on firm-level outcomes. As part of my research initiatives, I compile open-source large-scale firm-level datasets. My research has been featured in top academic journals, including American Economic Review, and Research Policy. I received my PhD in Business Administration (Strategy) from Duke University’s Fuqua School of Business. I was the 2021 recipient of Fuqua's School of Business Best Dissertation Award. I earned an MBA from the Hebrew University of Jerusalem, and a B.A. in Economics from Tel-Aviv University. Prior to academia, I worked in the Banking Industry and was an Economic Consultant in the Ministry of Defense Budget Department, Israel. I am a co-founder of Fuqua-STAGE (Society to Advance Gender Equality in Business Academia) and an advocate for women in STEM.

JOB MARKET PAPER
“Sitting on the fence: integrating the two worlds of scientific discovery and invention within the firm”
Applying a within-firm perspective to the topic of the division of innovative labor, I explore how the organization of scientific discovery at the firm level– specialized or integrated with invention- conditions the firm’s outcomes. Using data on inventors and authors related to U.S. publicly traded scientific firms for the period 1980-2015, I show that integration, which supports the connectedness of scientific and invention practices within the firm, is related to a tradeoff between short-term applied R&D and long-term fundamental R&D. While integration is beneficial for invention, it has adverse effects on its scientific output, which decrease invention in the long run. I find that the negative relationship between integration and publication reduces the direct increase in patents due to integration by approximately 60%. I further show consistent implications in terms of market value. Finally, I present three main determinants that condition this tradeoff: reliance on science, stage of technology, and market for technology. The paper deepens our understanding of the determinants and tradeoffs associated with the strategic choice of scientific discovery organization.
DISCERN: Duke Innovation & SCientific Enterprises Research Network
Patents, scientific articles, and NPL citations matched to Compustat firms over the period 1980-2015. The dataset traces more than 4,000 U.S. publicly traded R&D firms' investment in science and invention for 35 years. It introduces a major extension and improvement to the historical NBER patent data (Hall, Jaffe, & Trajtenberg, 2001). First presented at the NBER (National Bureau of Economic Research) Innovation Information Initiative meeting in December 2019.
