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 research interest lies in two major domains. First is on Digital Media Industry with a particular focus on digitization of songs, movies, TV and books is affecting the incentives of content provider, content distributors as well public policy challenges in terms of innovation and copyright. In particular, he has examined the issue proliferation of distribution platforms including online piracy and its impact on traditional music, movies and books industry. Currently, he is investigating the issue of piracy and innovation. He was the recipient of Sloan Foundation Industry Study fellowship for his work in this domain. He is also co-director (with Mike smith) of a center called IDEA (Initiative for Digital Entertainment Analytics). The goal of the center is to study policy (copyright, intellectual property, innovation) and business issues (pricing, release times and so on) associated with the entertainment industry.
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.
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), what markets fail, and how to create a useful policy framework and how to measure the effectiveness of such policies. He has examined the issue of software vendors’ incentives to improve the quality of their products, and their incentives to release timely patches. In this context his work explores how different policies, competition and security standards shape these incentives. 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.
He is also interested in studying the effects of ICT (information and communication technologies). Some of his work is exploring the role of broadband in schools, role of online social networks on job search, music diffusion, and so on.
Dr. Telang has published extensively in many top journals like Management Science, Marketing Science, Information Systems Research, MIS Quarterly, and Journal of Marketing Research. He is 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.

1. Rajiv Garg, Rahul Telang, “Inferring App demand from publicly available data”, http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1924044 (forthcoming in MIS Quarterly)
In this paper, we show how using publicly available data one can estimate the demand for mobile applications. Mobile Apps is a highly dynamic and growing business. However, there is little information on the actual demand for these apps. Most providers like Apple or Android only publish aggregate numbers. However, similar to Amazon, these providers publish the rankings of these apps. Using two such publicly available lists (top 200 grossing and top 200 paid), we show that one can infer the demand for an app for any given rank. A key innovation is that we do not need access to any other data. We validate our estimates with various data sources and show the robustness of our approach.
We believe our results open avenues for many other interesting questions which depend on demand estimates.

2. Rodrigo Belo, Pedro Ferreira, Rahul Telang, “Impact of Broadband in School: Evidence from Portugal”, paper. (forthcoming in Management Science)
In this paper, we show how the use of broadband in classrooms affects student performance. The data is over 2005-2009 from middle schools in Portugal. We show that the more the schools use broadband (in terms of bytes), the worse the students perform in national exams (7-8% decline in grades). We term this as the distraction effect of the Internet. To overcome endogeneity, we use distance of schools from the Central office as an instrument. This is a property of DSL that the schools further from CO are likely to get less throughput. To test the distraction effect in more detail, we collect survey data from schools regarding which applications they allow. Since YouTube is likely to be a source of distraction and bandwidth intensive, we show that the schools which allow YouTube (as opposed to those which block it), are more likely to suffer from Internet use.
