We estimate a model of newspaper demand that incorporates slant explicitly, estimate the slant that would be chosen if newspapers independently maximized their own profits, and compare these profit-maximizing points with firms’ actual choices. We find that readers have an economically significant preference for like-minded news. Firms respond strongly to consumer preferences, which account for roughly 20 percent of the variation in measured slant in our sample.
Very cool. Thanks for sharing. Since it is a like minded result, I obviously have a significant preference for it. (Unlike the sibling to your comment, which was obviously produced by someone from the other team)
