The Price Is Sexist: Taste Based Discrimination by Contestants on the Price Is Right
We report evidence of taste-based discrimination by contestants in the One Bid game on The Price Is Right television show. One Bid contestants bid sequentially in an attempt to bid closest to the price of a prize without exceeding it. The last bidder in the game has a dominant “cutoff” strategy of bidding $1 more than another contestant, but this strategy also leaves the target contestant with ...
متن کاملThe wisdom of the crowd playing The Price Is Right
In The Price Is Right game show, players compete to win a prize, by placing bids on its price. We ask whether it is possible to achieve a "wisdom of the crowd" effect, by combining the bids to produce an aggregate price estimate that is superior to the estimates of individual players. Using data from the game show, we show that a wisdom of the crowd effect is possible, especially by using model...

We collect two novel datasets of product images and their MSRP prices for this purpose: a bicycle dataset and a car dataset. We set baselines for price regression using linear regression on histogram of orie...
