Question

Suppose the inverse demand and supply for milk in the European Union (EU) is given by p=107-070d and p=4+0.2Q. Where the quantity is in millions of litres and the price is in cents per litre. Assuming that the EU does not import or export milk. Answer the following: Write your answers to 2 decimal places. a) Find the market equilibrium quantity, Q b) Find the equilibrium price, p c) Find the consumer surplus at the market equilibrium. d) Find the producer surplus at the market equilibrium. e) The European farmers successfully lobby for a price floor of P = 37 cents per litre. What will be the new quantity sold in the market, Q? f Find the new consumer surplus after the price floor. g) What is the deadweight loss from the price floor?

Explanation / Answer

(a) In equilibrium, demand price equals supply price at a common quantity (Q* = Qd = Qs).

107 - 0.7Q* = 4 + 0.2Q*

0.9Q* = 103

Q* = 114.44

(b) When Q = 114.44, p = 4 + (0.2 x 114.44) = 4 + 22.88 = 26.88

(c) From demand function, when Qd = 0, p = 107 (Reservation price)

Consumer surplus = Area between demand curve & market price = (1/2) x (107 - 26.88) x 114.44

= 57.22 x 80.12 = 4584.47

(d) From supply function, when Qs = 0, p = 4 (Minimum acceptable price)

Producer surplus = Area between supply curve & market price = (1/2) x (26.88 - 4) x 114.44

= 57.22 x 22.88 = 1309.19
