Home Page  Research  Teaching  Economics of IT   For Startups  Calculus


I am fascinated by how information technology transforms industries and markets. My current program of research is based on the belief that the there are numerous aspects of IT industries and industries transformed by IT that are sufficiently unique to warrant developing new theory that improves our understanding of their economics.

Some of the questions my recent papers address include how networks affect economic outcomes, how to price digital goods, how to effectively manage piracy using pricing policy and DRM, bounded rationality and network effects, and how IT affects allocation in socially postive ways.

I'm also studying price dispersion in the Manhattan beer market.
