The citation recognized Matt{\textquoteright}s {\textquotedblleft}fundamental contributions to\ our understanding of the economic forces driving the creation of media products,\ the changing nature and role of media in the digital environment, and the effect of\ media on education and civic engagement.{\textquotedblright} In addition to his work on the media,\ Matt has made a number of significant contributions to empirical industrial organization\ more broadly, as well as to applied economic theory. In this essay, I highlight\ some of these contributions, which are listed on Table 1. I will be referring to these\ papers by their number on this list.Matt earned both his AB in 1997, and, after a brief career in the theatre, his\ PhD in 2004 from Harvard, where he began to work on the media. At Harvard he\ also met Jesse Shapiro, his close friend and collaborator. I was one of Matt{\textquoteright}s (as well\ as Jesse{\textquoteright}s) thesis advisors. From Harvard, both Matt and Jesse moved to Chicago\ Booth School, where their research truly thrived and they contributed to a fantastic\ group of applied economists.}, url = {http://pubs.aeaweb.org/doi/pdfplus/10.1257/jep.29.1.181}, author = {Andrei Shleifer} }
