QD = 160 - 8P
Where quantity is in tens of thousands of apartments and price is the average monthly rental rate in hundreds of dollars. The agency has determined that the supply of apartments is given by
QS = 70 + 7P
a) Equilibrium under no regulation has Qs = Qd
70 + 7P = 160 - 8P
15P = 90
P = 600 per month
Q = 1,120,000 apartments
b) At P = 300, we have Qd = 160 - 8*3 = 1,360,000 apartments while Qs = 70 + 7*3 = 910,000 apartments. Hence there is a shortage of 450,000 apartments. A total of 910,000 apartments are rented at a rent of $300 per month
c) At P = 900, we have Qd = 160 - 8*9 = 880,000 apartments while Qs = 70 + 7*9 = 1,330,000 apartments. Hence there is a surplus of 450,000 apartments. A total of 880,000 apartments are rented at a rent of $900 per month
d) Deadweight loss from P = 300 is DWL = 0.5*(8.625*100 - 3*100)*(1120000 - 910000) = 59.0625 million
Deadweight loss from P = 900 is DWL = 0.5*(9*100 - 2.571*100)*(1394320 - 880000) = 165.32 million
Hence lower deadweight loss is from P = 300 which is 59.0625 million
