My main research interests are in the economics of digitization and in empirical industrial organization. I am particularly interested in the effects of technological change on markets, consumers, and welfare.

My research has examined the effects of digitization on the supply of recorded music and on the welfare benefits of new products. I have also studied the effectiveness and consequences of copyright enforcement policies and their effect on consumer behavior, the interaction between distinct music consumption channels, and the welfare effects of digital music and movie trade. I am additionally studying how music and movie streaming platforms (such as Spotify and Netflix) affect content availability and production as well as global consumption patterns.
