An Economic Analysis of TV Advertising Profitability
Professor Anna Tuchman of Northwestern’s Kellogg School of Management presented an economic analysis of the effectiveness of a major portion of the U.S. linear television advertising spend, worth $66B in 2019. The study, conducted with Bradley Shapiro and Günter Hitsch of the University of Chicago’s Booth School of Business, investigated the elasticity of actual sales for 288 distinct CPG brands on the basis of brand-specific ad spend as captured by Nielsen store and household panels along with Nielsen Ad Intel data. They used log-log regression and flexible machine learning algorithms. Their goal is to help firms evaluate ad campaign effectiveness with the hope their measurement will help make better ad spend decisions.
