Antitrust For Kids: Watch Out For Predatory Halloween…Pricing!!

At Argo Elementary, a group of kids gathers daily at lunch to buy and sell candy. The trading activity is a longtime tradition at Argo and it's taken very seriously—more like a competitive sport than a pastime.

Candy trading doesn't end once a 5^th grader graduates from Argo. It continues across town at Chicago Middle School—but instead of lunch, candy trading happens there at the close of each school day. (The middle school had banned lunchtime trading due to several disputes that grew out of hand.)

Now here's where it gets complicated, and nobody knows why it works this way, but the average lunchtime price at Argo determines the starting price for trades later in the day at Chicago.
