Affordability is a big talker at the Fair this year. Dr. Tyler Schipper is an economist at the University of St. Thomas. He and a team of students have been tracking the annual price changes at the Fair. They call themselves the Purple Price Trackers. He joins Jason to go over the index he’s created, the data and his thoughts behind it. They talk about how paying with cards vs cash, where serves you best value and who Dr. Schipper would like to get more information about.
