1. Potato growers have a mandatory demand expansion program where all growers pay a certain amount to fund a promotion program for tomatoes. You have estimated the following market supply and demand functions for potatoes, which include a demand shifter for generic potato promotion:
Qd = 15 - P + 0.1PROM
Qs = 5 + 2.5P TC = 0.2Qs
where: Qd = quantity demanded of potatoes, measured in million pounds, P = price of potatoes measured in $ per pound, PROM = total generic promotion in million dollars, Qs= quantity supplied, measured in million pounds, TC = total production costs, but does not include the promotion costs.
(a) Assume that in 2019, PROM = 2.5. Calculate the equilibrium price, quantity, total industry net revenue (total revenue minus TC).
(a) Qd = 15 - P + 0.1PROM = 15 - P + 0.1*(2.5) = 15 - P + 0.25 = 15.25 - P
At equilibrium, Qd = Qs.
So, 15.25 - P = 5 + 2.5P
So, 2.5P + P = 15.25 - 5
So, 3.5P = 10.25
So, P = 10.25/3.5
So, P = 2.93
Q = 15.25 - P = 15.25 - 2.93 = 12.32
So, Q = 12.32
Total Revenue, TR = P*Q = (2.93)*(12.32) = 36.0976
TC = 0.2Q = 0.2*(12.32) = 2.464
Net revenue = TR - TC = 36.0976 - 2.464 = 33.63
Thus, net revenue = 33.63

[1] A perfectly competitive aluminum producer is currently producing a quantity where the market price is $0.67 per pound (i.e., 67 cents per pound), average total cost is $0.70, and average variable cost of $0.60 (which corresponds to the minimum point on the average variable cost curve). Would you recommend this firm expand output, contract output, or shut down in the short-run? Provide a graph to illustrate your answer. [2] Suppose the local crawfish market is perfectly competitive, with the...
Please,all questions should solve,exam questions,so important! (10) The annual demand for liquor in a certain state is given by the following equation: QD-500.000-20.000P where P is the price per gallon and Qo is the quantity of gallons demanded per year. The supply of liquor is given by the equation Qs-30.000P. Now assume that a unit tax of iS is levied on the sellers of the commodity (i.e. statutory incidence is on the producers). (a) Just by looking at the slopes...
2. Consider again the avocado example, where demand and supply functions are Qd 160 40p Qs-50+15p Suppose a severe drought hit California, and the state government decided to subsidize farmers 40 cents for each pound of avocados produced. (Unit: Q is million pounds of avocados, and p is dollars). (1) With government subsidy, write down the functions of demand and supply. (2) What is the new equilibrium price and quantity of avocados? (Rounding to two decimal places) (3) Plot the...
