Rahul Telang is professor of Information systems and Management at the Heinz College at Carnegie Mellon University. He has been at the Heinz College since 2002 and predominantly teaches in the School of Information Systems and Management.

Professor Telang’s is broadly interested in how Information and Communication Technologies (ICTs) and associated digitization of information impact consumers, business and policies. Within this thread, his interest lies in two major domains. First is Digital Media Industry with a particular focus on how digitization (and associated piracy) in copyrighted industries is affecting the incentives of content provider, distributors and users. His research is directed towards understanding and shaping an optimal copyright and intellectual property policy in the Digitization Era. He was the recipient of Sloan Foundation Industry Study fellowship and a number of Google Faculty awards. He is also co-director of a center IDEA (Initiative for Digital Entertainment Analytics).  He has worked extensively with industry and policy makers on variety of issue surrounding digitization of Media.

His second area of work is on economics of information security and privacy. His key interest is in understanding the incentives of various parties (users, firms and hackers), why markets fail, how to create a useful policy framework and how to measure the effectiveness of such policies. His work explored the controversy surrounding vulnerability disclosure, vulnerability markets and their role in generating optimal outcomes. Recently, he has been examining the role of data breach disclosure laws on identity thefts. He was the recipient of NSF CAREER award for his work on economics of information security. He is also part of Cylab and Institute for Infrastructure Protection (I3P). Currently, he is working on a large NSA funded project on examining home users’ security and privacy behavior.

Some of his other work has explored the role of broadband in schools, ICTs in for form of EMR (Electronic Medical Records) in hospitals, issue of number portability, exclusivity and so on in mobile industry.

Dr. Telang has published extensively in many top management and policy journals like Management Science, Marketing Science, ISR, MIS Quarterly, Journal of Industrial Economics, Journal of Policy and Management, and NBER chapters. He is a senior editor at ISR (Information Systems Research) and MIS Quarterly. He has organized many conferences and workshops and many of his papers have received top honors at journals and conferences. He has had large external funding over the years for many of his projects.

He is also deputy director of a large and ambitious project called “living analytics” (LARC) which is a joint endeavor between Singapore Management University and The Heinz College and CMU.  He will be directing projects related to digital and social media. Currently he is the director of the PhD program at the Heinz College.

Recent Working Papers


1.       Daegon Cho, Anuj Kumar, Rahul Telang. “iPhone Exclusivity, Smartphone Demand and Welfare”


This study investigates the impact of Apple’s exclusivity arrangement with wireless carriers on the demand for smartphones. To measure how this limited access would change smartphone sales and consumer welfare, a structural model of consumers’ demand is developed and estimated on a unique dataset comprising of a panel data of mobile handset sales in six developed countries. The parameters estimated by this model suggest that the exclusive arrangement resulted in loss in iPhone sales and an overall loss in smartphone sales in the six countries. Moreover, the restricted iPhone availability also led to a substantial loss in consumer welfare.



2.      Rodrigo Belo, Pedro Ferreira, Rahul Telang, “Spillovers from Wiring School with Broadband: Critical Role of Children”


In this paper we model and measure the roles that broadband use by children at school play in the decision to adopt Internet at home. We use data from Portugal on household Internet penetration and on schools’ broadband usage. We use two different sets of instruments for the schools' broadband use to alleviate endogeneity concerns. We find that broadband use at school leads to higher levels of Internet penetration in neighboring households. The average broadband use in schools across our dataset (1.65 GB/student in 2008 plus 2009) increased the probability of Internet adoption by 24% in households with children, while no statistically significant effect is found in households without children.


3.      Zia Hydari, Rahul Telang, William Marella, “Saving Patient Ryan: Can Hospital IT make patient care safer? Evidence from Pennsylvania Hospitals”.


Patient safety is expected to benefit from health information technology (IT) but the evidence of health IT’s impact on safety is equivocal. We study the effect of advanced Electronic Medical Records (EMRs) on patient safety using panel data from Pennsylvania hospitals for 2005–2012. State law mandates Pennsylvania hospitals to report patient safety events to Pennsylvania Patient Safety Authority, and our data set includes all reported patient safety events in Pennsylvania hospitals for 2005-2012.  We find that hospitals benefit from a 27% decline in patient safety events attributable to advanced EMR adoption. We also find that several important subcategories of patient safety events contribute to the overall benefit --- events due to medication errors decline by 30% and events due to complications decline by 25%. Our results hold against a number of robustness checks on identification.
