I want to know how to solve d) from the next exercise:

1'16 Regulating Medications: Consider a rm [player 1} that produces a unique drug that is used by a consumer (player 2]. This drug is regulated by the gov- ernment so that its price is p = IS. This price is tted1 but the quality of the drug depends on the manufacturing procedure. The \"good\" (G) manufacturing pro- cedure costs 4 to the rm and yields a value of 9 to the consumer. The "bad\" (3} manufacturing procedure costs [I to the rm and yields a value of 4 to the con- sumer. The consumer can choose whether or not to buy at the price p. and this decision must be made before the actual manufacturing procedure is revealed. However, after consumption, the true quality of the drug is revealed to the consumer. The choice of manufacturing procedure, and thus of the cost of pro- duction1 is made before the rm knows whether the consumer will buy or not. a. Draw the game tree and the matrix of this game, and nd all the Nash equilibrie h. Now assume that the game is repeated twice. {The consumer learns the quality of the product in each period only if he consumes.) Assume thateach player tries to maximize the {nondiscounted} sum of his stage payoffs. Find all the subgame-perfect equilibria of this game. c. Now assume that the game as repeated innitely many times. Assume that each player tries to maximize the discounted sum of his or her stage payoffs. where the discount rate is 5 E (l), 1). What is the range of discount factors for which the good manufacturing procedure will be used as part of a subgame-perfect equilibrium? d. Consumer advocates are pushing for a lower price for the drug. say 5. The rm wants to approach the Food and Drug Administration and argue that if the regulated price is decreased to 5 then this may have dire consequences for both consumers and the rm. lCan you make a formal argument, using the given parameters, to support the rm? What about the consumers
