Agricultural goods
1. For each of the events described below, demonstrate how the production possibility
curve for agriculture goods and manufacturing goods will shift.
Manufacturing goods
a. A drought in the Midwest reduces agricultural yield per acre.
b. Advances in computer technology lower the cost of producing manufactured
goods but do not affect the cost of producing agricultural goods.
c. Civil war disrupts the production of all goods equally in the United States.
2. Point out the faulty reasoning in each of the following statements
a. You win a free, nontransferable ticket to a Sheryl Crow concert. Since the ticket is
free, you decide to go because “it’s no skin off my back.”
b. You have purchased 5 premium apples for $1.99 a pound. When you get home
from the grocery store, however, you realize that the apples are not crisp as you’d
expected, but mushy. Since you paid top dollar for these apples, you decide you
have to eat them.
c. Wages in China are lower than in the United States. Therefore, China has a
comparative advantage in the production of all goods.
3. State in words and show with a graph the effect of the following events on
equilibrium price and quantity of the market given.
a. Beetle infestation decimates tobacco crop. Market: cigars.
b. Digital image albums become the rage among households while improved
technology reduces the cost of producing digital cameras. Market: digital
cameras.
c. Hurricanes in the Gulf coast cause gasoline supply disruptions while the summer
travel season ends. Market: gasoline.
4. Calculate the price elasticity of demand for the following products and state whether
demand is price elastic, inelastic, or unit elastic.
a. Raw sugar prices rose by 3% and raw sugar consumption declined by 2%.
Product: raw sugar.
b. Recent research revealed that a 10% increase in the price of cigarettes reduced
cigarette smoking among 8th to10th graders by 10%. Product: cigarette purchases
among 8th to 10th graders.
c. The price of luxury cars increases by 4 percent while the quantity demanded
decreases by 8%. Product: luxury cars.
5. Would you expect the following producers to support or not support an increased tax
on beer? Explain your answer using the following information:
Commodities
Cross-price elasticity
Beer in response to price changes in wine
0.23
Hard liquor in response to price changes in beer

Quantity of shoes
a.
Demonstrate the effect of a $15 tax per pair of shoes on equilibrium
quantity and equilibrium price.
b.
What is the new equilibrium price of shoes? Why didn’t the price rise by
the amount of the tax?
c.
Shade the amount of the tax paid by consumers and label it A. What is its
numerical value?
d.
Shade the amount of the tax paid by producers and label it B. What is its
numerical value?
e.
Within this range of prices, is demand more or less elastic than supply?
Explain your answer. Answer the question without calculating elasticities.
