Choose four questions to answer. Questions draw from course lectures, discussions, and readings.
You may discuss the questions, but you must write your own responses and turn in your own work. Answers that are substantially similar will be interpretted cheating and punished accordingly. I will not answer any questions about course content during while the exam is outstanding.
Each question is worth 25 points. This assignment is due to me by email by 8:00 PM Saturday, April 11 by email as a PDF. Starting at 8:01, you will lose 2 points for every hour it is late.
If appropriate, you must be able to talk with some familiarity about arguments put forth in our readings, when relevant (informally, as in “According to Smith…”).

- (10 points) Under what conditions is this market with a single producer both a competitive outcome and a Nash equilibrium?
