Extra Credit

In an effort to explain the equilibrium concept of optimal response, I offered my students the chance to earn a point of extra credit by winning the following game:

Pick a number between 1 and 100. The highest number in the class gets a point of extra credit

The answers?

100
100
100
23
100
36

I awarded four students extra credit for performing better than a random number generator. It's a good thing I teach at a school that's been called a "New Ivy League" institution.
