Skip Crooker (Decision Support), along with Aju Fenn (Colorado College), have published a paper titled, "The Dollar Value of an NFL Rivalry." The analysis within the paper quantifies the dollar value of a divisional rivalry between the Minnesota Vikings and the Green Bay Packers by asking survey respondents how much they would be willing to pay to preserve the two divisional rivalry games played per year. This paper can be found as a part of the  Sports Economics, Management and Policy book series (SEMP,volume 23).
