QUESTION 1 (10 Points)
Answer each of the following questions by drawing a graph that
represents the initial equilibrium condition and the resulting new
situation from the effect. Label the graphs carefully and provide a
written explanation as well.
a. Consider the market for reusable coffee mugs that is
initially in a market equilibrium. Suppose that a more efficient
production process has been developed, which reduces the cost of
production and that people are now more aware of environmental
impacts so they try to reduce and reuse. Given these events, what
will happen to the equilibrium price and quantity in the market for
coffee mugs?
b. Consider the market for hoodies that is initially in a
market equilibrium. Suppose that hoodies are becoming more popular,
while concurrently, the number of people that plan to purchase any
hoodies decreases. Given these events, what will happen to the
equilibrium price and quantity in the market for hoodies?
QUESTION 2 (10 Points)
Answer each of the following questions by providing a written
explanation.
a. The price elasticity of demand for pencils is equal to 1.
What does the statement mean if the price of a pencil decreases by
20%? What type of good is a pencil?
b. The income elasticity of demand for pencils is equal to 2.
What does the statement mean if income increases by 10%? What type
of good is a pencil?
c. The cross price elasticity of demand for pencils and pens
is +2. What does the statement mean if the price of a pen decreases
by 5%? What is the relationship between the two goods?
d. The cross price elasticity of demand for pencils and
erasers is -3. What does the statement mean if the price of an
eraser increases by 10%? What is the relationship between the two
goods?
QUESTION 3 (10 Points)
Answer each of the following questions by determining if the
statement is true or false and provide your reasoning.
a. The price elasticity of demand for gasoline in the short
term is more elastic than it would be in the long term.
b. The price elasticity of wine is more elastic for a
low-income individual than a high-income individual.
c. The burden of a tax is higher on the consumer if the demand
is elastic and the supply is inelastic.
d. When the ceiling price is below the equilibrium price, then
the change in producer surplus is positive.
QUESTION 4 (10 Points)
Answer each of the following questions by showing any
calculations required or by providing a written explanation.
Suppose that in a year a European car manufacturer can produce
600,000 sedans or 100,000 trucks, while a Canadian car manufacturer
can produce 300,000 sedans or 300,000 trucks.
a. (2 points) The two countries are currently not engaged in
international trade. Suppose that each country allocate half a year
in the production of each good, what will be the total world
production of cars and trucks in a year?
b. (4 points) What is the opportunity cost of producing a
sedan in terms of a truck and the opportunity cost of producing a
truck in terms of a sedan for both countries?
c. (2 points) Which country should specialize in sedan? In
trucks?
d. (2 points) If both countries were to specialize and open to
trade, what will be the total world production of cars and trucks
in a year?
QUESTION 5 (30 Points)
Answer each of the following questions by showing any
calculations required or by providing a written explanation.
Jasper works for the government and his job is to analyze the
market for apples. He found that the market demand function for
apples is QD = 50 - 5p and the market supply for apples is QS = 10
+ p, where Q is the quantity of apples demanded/supplied and p is
the price of apple per pound. The government is looking to limit
the production of apples and is considering various intervention
options.
a. (3 points) Suppose that John initially does not know the
demand function nor the supply function for applies, but he has the
following information through observing the market. He notice that
when the price of apples increased from $4.00 to $4.10 per pound,
the quantity of applies demanded fell from 30 to 28 pounds. What is
the elasticity of demand for apples? Is it elastic, unit-elastic,
or inelastic? Using this estimate, by how much would price increase
if the quantity demanded to be restricted to 20 pounds from 25
pounds (a 20% decrease in the quantity demanded of apples)
b. (9 points) Given the demand and supply functions, determine
the current equilibrium price and quantity for apples. Graph the
market equilibrium for apples. What is the consumer surplus (CS),
producer surplus (PS), total surplus (TS), government revenue (GR),
and dead weight loss (DWL) at the equilibrium?
c. (8 points) The first option is to implement a production
quota that restricts the production of apples from the current
equilibrium supply to 20 pounds of apples. What is the consumer
surplus (CS), producer surplus (PS), total surplus (TS), government
revenue (GR), and dead weight loss (DWL) with this quota? Show the
effects of the quota on a diagram, and label the welfare measures,
if applicable.
d. (8 points) The other option is to implement a tax of $2.67
on the producer. What is the consumer surplus (CS), producer
surplus (PS), total surplus (TS), government revenue (GR), and dead
weight loss (DWL) with this tax on the producer? Show the effects
of the tax on a diagram, and label the welfare measures, if
applicable.
e. (2 points) Which government intervention (a quota or a tax)
would the consumers and the producers prefer, if they had to
choose?
