Game Theory of The Price is Right: Part 2

In my last post, I discussed some game theory behind the Cliffhangers game on The Price is Right. And while watching the stupidity of Cliffhangers players got me angry, what really got me thinking was the bidding itself.

To get up on stage (which comes with a chance to win bigger prizes), four contestants take turns guessing the value of an item (usually several hundred dollars). The one with the closest guess to the item's actual value, without going over, wins the item and gets to go up on stage.

Frequently, people make really dumb guesses. Someone will bid, say, $420 for an item, and another contestant will subsequently bid $415, giving themselves a $5 window in which to win the item. But more interesting is whether or not contestants decide to bid $1 above someone else. Frequently, someone will bid, say, $475 after another contestant has bid $420. They could have bid $421 (and indeed this does happen, as in the video below), but in the unwritten etiquette of The Price is Right, it's viewed as a low blow.

Game theory of The Price is Right: Part 1

In an attempt to improve my French, I have discovered a newfound appreciation for The Price is Right. Having watched the show as a kid but forgotten about it in recent years, I was excited when a Québecois version of Bob Barker's classic game show was launched this fall. I have found that it is an enjoyable way to keep up my French vocabulary.

It's also the first time that I've watched the show on a regular basis since studying economics, which can make for a surprisingly frustrating experience. For instance, on Cliffhangers (the "yodelling game"), I find myself cringing when contestants make their final bid.
