Answer: excess demand, underestimate
Step-by-step explanation:
P= 1200 - 2Q
300= 1200 - 2Q
2Q = 1200 -300
2Q = 900
Q = 900/2
Q = 450
Quantity demanded is 450 units
Quantity supplied Q - P = 300
Excess demand = 450 - 300 = 150
The policy will lead to excess demand of 150 per month.
P= 1200 - 2Q
P= 1200 - 2(300)
= 1200 - 600
= 600
Willing to pay price is $600.
Deadweight loss = 0.5 × (Price buyers are willing to pay - ceiling price) × (market quantity supplied - ceiling quantity supplied)
= 0.5(600-300)(400-300)
= 0.5(300)(100)
= 15000
Deadweight loss is $15000
The welfare loss underestimate the actual loss
