Why can Q-learning sustain collusion? a. Because collusion maximizes firms' profit. b. Because collusion is the Nash equilibrium of the pricing game, even if it is played only once. c. Because the algorithm takes into account future profits, and learn that price cutting today will lead to price war tomorrow. d. Because firms use the algorithm to communicate with each other and sustain collusion.

Suppose a platform tries to recommend the best movie to Ann and Ben. Movie 1's quality is uniformly distributed from 0 to 1. Movie 2's quality is uniformly distributed from 0.5 to 1.
Suppose the platform recommends a movie to Ann and Ben at the same time. What are the expected quality of movie 1 and 2, and which one should it recommend?
0.5, 0.5, movie 1.
0.75, 0.5, movie 1.
0.5, 1, movie 2.
0.5, 0.75, movie 2.
