Auctions

Activity (20 minutes)

Goal. Contrast a sealed second-price auction with the open £5 auction from the first class and set up the question of truthful bidding.

Ask the class to repeat the £5 auction, but this time the highest bid wins and pays the amount of the second bid. Run it sealed: get everyone to write their bid on a piece of paper and reveal at the end.

Discussion (20 minutes)

Work through the Auctions chapter.

Discussion Point: After the definition of an auction, ask what the rules are for the sealed auction we just played.

Discussion Point: After two theorems ask why I chose the auction I did?

From the activity to the exam answer

The activity above is written up as a marked exam question: Question 1 (the in-class activity) on the Auctions page, with a full worked solution. Closing the loop here is the step that helps students who find exams hard: work through that question together, or set it as the immediate follow-up, so they see the game they just played turned into a full-mark answer.
