Tyler [Cowen] once walked into class the day of the final exam and he said. “Here is the exam. Write your own questions. Write your own answers. Harder questions and better answers get more points.” Then he walked out. The funniest thing was when a student came in late and I had to explain to him what the exam was and he didn’t believe me!
That is Alex Tabarrok, as related by Seth Roberts. As if I could admire Tyler more.
Future students of mine, beware?
