IS PhD Program
Prof. Chellappa's current research focuses on
economic, behavioral and technical aspects of electronic markets. In
particular, his research aims to understand how the adoption of the
Internet by both consumers and vendors has changed conventional views of
products and business transactions. His recent research includes:
Pricing issues in electronic markets
Pricing and Piracy of digital goods
Personalization and Privacy issues in online markets
Information technology standards and its role in shaping competition and alliance formation
The first known academic usage and definition of the term Cloud Computing appears to be provided by Prof. Chellappa in a talk titled Intermediaries in Cloud-Computing, presented at the INFORMS meeting in Dallas in 1997.
He suggested that this would be a new "computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits alone."
A follow-up research in 2002 refers to this definition and proposes pricing models specifically for active intranets.
Prof. Chellappa currently teaches in the MBA
and PhD programs at Goizueta. Please contact him directly for the
MBA CoursesBUS 551 - Process and Systems Management (MBA core)
This is the core Information Systems and Operations Management course. I have taught/currently teach this course in the full-time, evening and one-year MBA programs. Next offering: Spring 2011 (Evening MBA program)
This course covers the basics of operations management and information systems strategy. The course adopts an integrated supply-chain view of businesses. Topics include – Information Systems and Operations Strategy, Process fundamentals and analysis, Supply chain management, alignment of IT with business objectives, consumer profiling Security and privacy in online environments, and business process outsourcing and off-shoring.
BUS 556 - Analytics for e-Markets (MBA Elective)
The basis for many, if not most current online business models, is network economics. In this class, students will be introduced to the fundamentals of network economics through a series of hands-on problems, cases and data analysis. Along with network economics, we will also study pricing and versioning strategies specifically for electronic markets. At the end of the class students will be able to abstract real-world problems into workable components through analytical models and thinking. Industry speakers will add to this understanding. It is not the purpose of this class to teach data analysis or regression but we will use what you have learnt in your prior courses toward understanding problem definition, data identification, collection and analysis. While cases often directly provide students with data, a key business problem faced by many firms is identification of data itself. To this end students will be engaged in two group projects:
Google Online Marketing Challenge: In the previous years we have been part of the Google Online Marketing Challenge where students learn about two-sided markets through actual bidding for keywords. We shall continue this tradition. The Google Online Marketing Challenge is a great hands-on exercise for students in classes such as advertising, ecommerce, integrated marketing communication, management information systems, marketing and new media technologies. Students will manage and update a Google AdWords campaign and in process learn about valuing information and the nature of two-sided markets.
Quantifying Social Media Impact: This project is geared towards structured thinking for unstructured problems. For many businesses the rise of social media and user generated content is possibly a boon but also apparently a source of confusion. There is not only an abundance of social networking sites but also different categories of data. In this project, students will empirically show how social networking sites and user-generated content influence success of a product. You will identify, collect and analyze data to substantiate your claims.
PhD CoursesBUS 751 - Research Seminar in Information Systems II (Economics of Information Systems)
The course introduces students to seminal papers in the area of economics of information systems where the underlying theme is the application of economic theories to management. Through analytical models and empirical analyses, this course covers many topical areas including pricing and price-dispersion in electronic markets, pricing of information & digital products, and the emergence of privacy as an economic concept. Much time is devoted to understanding the research process and the analytical/empirical rigor that provides credence to any research finding.
Prof. Chellappa has also taught a number of other courses in different programsat the Marshall School of Business, USC. At the MBA level, these courses covered managerial and strategic aspects of information technology and at the undergraduate level, the courses were largely technical.
He has also taught in the Executive MBA program and has delivered live and packaged video lectures for industry executives on e-Business strategies. At USC, he has also designed and taught courses in the Masters in Medical Management program for healthcare professionals.
