Chicago Booth economist wins top economics honor

Every year the American Economics Association presents the John Bates Clark medal to the most promising economist under age 40 (WSJ writeup here.).  This year's winner is Chicago Booth's Matthew Gentskow.  Gentskow is one of the first economists to use big data in research.  Some of his most notable work involves media bias.  Do some newspapers lean left or right because of the perspective of the owner or does it reflect the characteristics of their readership?  Gentskow finds the latter, which makes sense if you think of who reads the NYT (liberal upper east siders) versus WSJ (finance and business types).
