BYPASS OPPORTUNITIES MATTER. Jake of Tufte's Economics Class picks up an old Argmax article describing Coca-Cola's research into a smart vending machine that would lower the prices on cold days and raise them on warm days.
There's just one little detail missing from the story. Some twenty years ago, Coca-Cola decided to change the formula for its cola. New Coke quickly went from being the sole offering to sharing with Coke Classic before being mercifully put aside. Pepsi hired Bill Cosby to have some fun with the competition. "This is the new product, which we told you was the old product last week," or something like that. It's not too difficult to envision a similar campaign. "Pepsi. Same Price, Different Day," or something like that.
