Question 1: Market for lobster – Revisited (52 points)
Consider again the market for Atlantic lobster presented in Q#1 of the previous
assignment where the annual demand and supply for lobster is given by the
following equations: 100 0.2 DP Q= − , and 25 0.1 SP Q= + , where P is the price per kg
in dollars, QD and QS are respectively the quantity demanded and the quantity
supplied (in thousand of Kgs). The government imposes a quota of 150 thousand
of kgs per year in the lobster industry and licenses are issued to allocate the rights
to harvest lobster.
1. Reconstruct the Demand and Supply curves to scale and show graphically
the equilibrium price P* and quantity Q* for lobster in the absence of quota
(8 points).
2. Denote the quota of 150 thousand of kg by Q and show it graphically.
Calculate the demand price and the supply price under this quota and show
them graphically (7 points).
3. Calculate the quota wedge (a.k.a. the quota rent) per Kg of lobster when 150
thousand of Kgs are sold? (7 points)
Another way to achieve the same reduction of the harvested lobster at 150
thousand of kgs per year is by imposing an excise tax. Consider now that the
government imposes an excise tax that is officially paid by the fishing industry.
4. Find the excise tax rate (in dollars) and fully explain which side of the
market is affect and how. Illustrate your answers graphically (8 points)
5. Calculate the tax revenue collected by the government in this scenario and
show it in the graph (7 points).

6. Calculate the incidence of the tax per kg (i.e. the portion paid by each
party), show it graphically and identify which party (consumers/producers)
pays the heavier tax burden. Illustrate your answers graphically (10 points)
7. What are the positive effects of these policies?(5 points)
Question 2: Effect of Taxes (48 points – 16 points per each case)
Consider each of three following cases involving taxes:
a. The government imposes an excise tax on the sale of all college textbooks.
Before the tax was imposed 1 million textbooks were sold every year at price
of $50. After the tax is imposed 600, 000 books are sold yearly; students pay
$55 per book, while publishers receive $30 per book.
b. The government imposes an excise tax on the sale of all airplane ticket.
Before the tax was imposed, 3 million airline tickets were sold every year at
a price of $500. After the tax is imposed 1.5 million tickets are sold every
year; travelers pay $550 per ticket, while airlines receive $450 per ticket.
c. The government imposes an excise tax on the sale of all toothbrushes.
Before the tax 2 million toothbrushes were sold yearly at a price of $2.00.
After the tax is imposed, 800,000 toothbrushes are sold yearly; consumers
pay $2.50 per toothbrush, while producers receive $ .75 per toothbrush.
For each case (16 points) calculate, fully explain and illustrate your answers with a
simple graph:
1) What is the tax rate, what is the incidence of the tax, which party pays the
heavier burden? (8 points).
2) What is the government revenue collected from the tax? (5 points).
3) What missed opportunities or inefficiency arise? (3 points).
