![A perfectly competitive industry has a large number of potential entrants. Short-Run total
cost is STC-0.1q²+40 and all firms have identical cost structure. They all minimize cost at
the same point where Min AC-MC and are at their long run equilibrium.
1-Find the quantity and the cost of every firm at that point.
If total market demand is P = 12-6002.
2-Find the total quantity demanded in the market and the corresponding number of firms.
3-Derive the market supply curve and calculate the total Welfare (CS+PS) in this market.
Due to an increase in Income consider that demand shifted to P = 15-6000.
4-What will be the new market equilibrium price and quantity? What will be the output/firm
in the short-run?
Since entry and exit is possible in the long-run cost.
5-What should the new number of firms become to satisfy this quantity and derive the new
market supply?
Go back to the original case where P = 12-600 and if the government imposes a $2/unit
tax on this market.
7-What should be the new equilibrium price and quantity? Who pays more of the tax the
suppliers or the consumers?
8-Calculate the new social welfare, the government revenue and the DWL.
Instead of the tax the government decides to open the market for international competition
where the price is $2 and impose a $1/unit tariff.
9-Calculate the increase in the original welfare and then the reduction in welfare due to the
tariff.
10-Calculate the government revenue and the DWL from the tariff.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3cd19f1d-c77d-44aa-9a91-5be4a7b77189%2F2d5360d4-2847-485b-b7db-b48e666e1610%2F6wmw56_processed.png&w=3840&q=75)
