Q2. Suppose market demand for movie tickets (in millions per year) is given by the equation Q_D = 19 - 2P, while tickets are supplied according to the market supply equation Q_s = P - 2.

a. Solve for the equilibrium price and quantity.

b. Graph your results.

c. Suppose the government imposes an excise tax on movie tickets of $2 each. An excise tax is a per unit tax on suppliers. In the graph in Q2 b, show the changes in the equilibrium price and quantity. Show the areas corresponding to total taxes collected, taxes paid by consumers, and taxes paid by producers.

d. Solve algebraically for:

i) The after-tax equilibrium price.

ii) The net price received by sellers

iii) Total taxes collected by government

vii) Taxes paid by producers.

e. Calculate the consumer surplus before tax

f. Calculate the consumer surplus after tax?

g. Is society better off with or without the tax (from the standpoint of your response to e and f above)?

h. Why?

i. Calculate the deadweight loss?

j. If the demand curve were steeper (but went through the equilibrium point you found in part a), would consumers pay a higher or lower share of the total taxes collected?

k. Why?

l. If the supply curve were steeper (but went through the equilibrium point you found in part a) but the demand curve unchanged, would consumers pay a higher or lower share of the total taxes collected?

m. Why?

Q3. Beer in Huntington sells for $2 a bottle, or in other words supply is completely elastic. The demand for beer (in millions of bottles) is given by: Q_d = 10 - 2P

a. Find the equilibrium price and quantity.

b. On Halloween weekend, the city of Huntington enacts a beer tax of $1 per bottle (paid by retailers) to attempt to get people to drink less.

Find the new equilibrium price and quantity and graph demand as well as both supply curves.

Does the tax achieve what it was supposed to do?

c. The beer tax expires before Christmas, and on Christmas Eve, Huntington has as much beer in town as is usually consumed. Unfortunately, Santa's elves get into the beer and consume 2 million bottles, and sellers respond by getting as much per bottle as they can.

Find the new equilibrium price and quantity.

Can you explain what is going on here given your answer to C above?

Q4. Bottles of wine (in tens of thousands) in Huntington are supplied and demanded according to the following:

Q_d = 100 - 4P

Q_s = 10 + 5P

a. Find the equilibrium price and quantity.

b. The Wine Snob Commission enacts a law that says any bottle of wine cheaper than $5 a bottle is illegal to buy or sell due to its poor quality.

What terminology can we use to describe this law?

Find and graph the new equilibrium price and quantity and describe the effect of the law.

The Wine Lovers Association retaliates and manages to get a law passed that only allows wine to be sold for no more than $8 a bottle in the hope that more people will become Wine Lovers like themselves as the lower price.

Find and graph the new equilibrium price and quantity, and find a term to describe this new law (or explain what is happening here.)

Will more people become Wine Lovers?

Q5. Suppose that the supply of low-skilled labor is given by:

L_s = 10W

where W is the wage (dollars per hour) and L_s is the quantity of low-skilled labor (in millions of persons employed each year). The demand for low-skilled labor is given by:

L_D = 80 - 10W

a. What will be the equilibrium wage rate and employment level?

b. Graph the supply and demand curves and show the equilibrium.

c. What is the point elasticity of supply in equilibrium?

Now, suppose that the government sets a minimum wage of $5 per hour.

d. How many people will be employed at that wage? Show the ceiling and the new equilibrium on your graph (preferably in a different color).

e. How many people want to be employed at this wage?

f. What is the arc elasticity over the demand curve for the two points on the demand curve?

g. Will there be any dead-weight loss? If so, calculate the size of the loss.
