CHAPTER 2 - REVIEW
I. Choose ONE correct answer
1. Assume that A’s supply is constant, A and B are substitute goods. The decrease in
B’s price will lead to:
a.
b.
c.
d.

a rightward shift in A’s demand curve
a rightward shift in B’s demand curve
a leftward shift in B’s demand curve
None

2. The Engel curve describes the relationship between:
a. Price and quantity demanded
b. Income and quantity demanded
c. Price and quantity supplied
d. Taste and quantity demanded
4. The increase in A’s inputs cost will cause:
a. Supply curve shifts to the left
b. Supply curve shifts to the left
c. Both supply and demand curves shift to the right
d. None
5. Given a downward-sloping demand curve and an upward-sloping supply
curve for a product, an increase in incomes will:
a. increase equilibrium price and quantity if the product is a normal goods
b. decrease equilibrium price and quantity if the product is a normal goods
c. have no effects on equilibrium price and quantity
d. reduce quantity demanded, but not shift the demand curve
6. Supply function excludes which of the following determinants?

a. Inputs price
b.Technology
c. Price of related goods and services
d. Expectation


7. The law of demand shows the inverse relationship between:
a. Expectation and quantity demanded
b. Price and income
c. Income and quantity demanded
d. Price and quantity demanded
8. The government sets up floor price in order to:
a. Protect producer/supplier
b. Protect consumer/ buyer
c. promote free international trade
d. none
9. A is elastic – demand good. A’s price increases by 10% will lead to:
a. a reduction in A’s quantity demanded by more than 10%
b. a reduction A’s quantity demanded by less than 10%
c. an increase in A’s quantity demanded by more than 10%
d. an increase in A’s quantity demanded by less than 10%
10.

Cross elasticity of A and B is equal to 2. A and B are:
a. Substitute goods
b. Complement goods
c. Independent goods
d. none

II. Answer true or false with short explanation and use

diagram if necessary
1. Inferior goods is the one with low quality
2. A and B are complement goods. The increase in A’s price causes the decline in B’s

price.
3. When both demand and supply curves shifts rightward, equilibrium price will

increase.
4. Taxation per unit imposed on less – elastic – demand goods makes the producers
bear the smaller part in total tax amount.


5. The increase in price of elastic – demand goods will reduce total revenue

State out demand and supply curve
State out equilibrium price and quantity
State out the actual quantity in the market at the price of P1 = 8.5$ and P2=11.5 $
Assume that the government impose a tax of 1$/ unit on producer. State out new
equilibrium price and quantity

2. B’s demand and supply curves are as follows:
P = 3Q – 12
P = 18 – 2Q
(P: $/kg, Q: kg)
a. State out equilibrium price and quantity
b. The government sets up the ceiling price at 4$/kg and supply the shortage. State

out the actual price and quantity in the market.
c. Suppose that the government wants the price and quantity to be equal to the result

in question (b) but by subsidy for producer rather than by setting ceiling price.
State out the subsidy level per kg. In this case, who will get more benefit, supplier
or consumer?
