Guessing game Guess a number 0 to 100. The guess closest to 2/3 the average number wins a prize. Ties will be broken randomly. Please write your name and your guess on the piece of paper and turn it in to me. Don’t let others see your guess!

Guessing game Guess a number 0 to 100. The guess closest to 2/3 the average number wins a prize. Your average was … Wharton average 40 Caltech UG average was 30 (10% at 0) Economics Phds 25 CEO average also 40. What would we expect if everyone is rational and thinks everyone else is rational? Now repeat this!

Graph of guesses (Exeter UGs) Average was 36.7 (winning guess 24.5) Six guesses were above 66.66

Exeter UG 2 nd round guesses Average was 12.4 (winning guess 8.3) One guess was above 66.66

Moral of the Story Sometimes markets aren’t always rational or in “equilibrium”. This Guessing game is like a market bubble. Sometimes theory based on rationality doesn’t predict perfectly. You shouldn’t ignore theory (even when it is wrong). Otherwise, it may catch you unexpectedly. You just participated in an experiment. These are useful to gain insight for both the participants and the experimenter.

Corporate Strategy Methods We will study what economics has to offer to explain Corporate Strategy. This as with the guessing game may help you predict things where are going. We will combine this with experiments to both –better understand the theory. –gain experience on when and when not the economic forces be the driving force in the market.
