For cach of the scenarios, calculate the surplus and indicate if it is a producer surplus or a consumer surplus. Alice is willing to spend $30 on a pair of jeans, and has a coupon for $10 off which she found online. She selects and purchases a $35 pair of jeans which cost $35 pre-discount. Roy is willing to pay $2.50 for a sports drink.

1. Consider the market for cell phones in Celltown. Suppose that the inverse demand curve is P = -2Qd + 300 and that the inverse supply curve is P = 3Qs + 50. a. Sketch the inverse supply and inverse demand curves. b. Calculate the equilibrium price and quantity. c. Compute consumer surplus (CS), producer surplus (PS), and total surplus. d. Suppose the Mayor of Celltown institutes a price floor of P = $250 in order to promote the new technology. It is illegal to sell cell phones at a price below P. What is the quantity transacted in the market with the price floor? e. Compute the change in CS and the change in PS. f. Compute the change in total surplus. If you were an economic advisor to the Mayor whose goal is to maximize the total surplus of the city, would you advise continuing the policy or not? Explain. g. A representative of the Association of Cell Phone Manufacturers arrives at the Mayor's office to lobby against eliminating the price floor. i. Explain why economic theory…
