. Consider a big oligopolist and a small oligopolist that are Cournot competing in the same market. The large oligopolist has minAC=5, which occurs at q = 100, and the small oligopolist has minAC=10, which occurs at q = 10.

(d) Under what conditions would this duopoly reduce down to a natural monopoly?

(e) For some linear demand of your choice, actually solve for the numerical equilibrium if marginal costs are linear.

(f) For your example, is duopoly more or less efficient than the big oligopolist operating as a monopoly?
