1: The concept of opportunity cost is best defined as:
A) The total monetary expenditure required to produce a good
B) The value of the next best alternative forgone when a choice is made
C) The sum of all sunk costs incurred in production
D) The difference between total revenue and total cost
Correct Answer: B
Opportunity cost includes both explicit and implicit costs, representing the highest-valued
alternative sacrificed. Option A ignores implicit costs, C refers to sunk costs which are
irrelevant, and D defines profit, not opportunity cost.
2: Which of the following points on a production possibilities frontier is attainable but
inefficient?
A) A point outside the frontier
B) A point on the frontier
C) A point inside the frontier
D) A point beyond the horizontal axis
Correct Answer: C
Points inside the PPF indicate underutilization of resources, hence inefficient but attainable.
Points on the frontier are efficient; outside points are unattainable; beyond axis is not
meaningful.
3: If an economy can produce either 100 units of food or 50 units of clothing, what is the
opportunity cost of producing one unit of clothing?
A) 0.5 units of food
B) 1 unit of food
C) 2 units of food
D) 50 units of food
Correct Answer: C
To produce 50 clothing, the economy gives up 100 food, so 1 clothing costs 100/50 = 2 food.
Option A is inverse, B assumes equal trade, D gives total not per unit.

4: A shift of the production possibilities frontier outward could be caused by:
A) An increase in unemployment
B) A technological advancement in one industry
C) A decrease in the labor force
D) Movement from inside to on the frontier
Correct Answer: B
Technological progress expands productive capacity, shifting PPF outward. Unemployment or
decreased labor force reduces output but does not shift frontier; movement along frontier is not a
shift.
5: The law of demand states that, ceteris paribus, as price increases:
A) Quantity demanded increases
B) Quantity demanded decreases
C) Demand decreases
D) Demand increases
Correct Answer: B
The law of demand indicates an inverse relationship between price and quantity demanded.
Options C and D confuse change in demand (shift) with change in quantity demanded
(movement).
6: An increase in consumer income will shift the demand curve for a normal good to the:
A) Left
B) Right
C) No shift
D) Left if price also rises
Correct Answer: B
For normal goods, higher income increases demand at every price, shifting demand right. Left
shift would be for inferior goods; no shift ignores income effect.
7: If the price of a substitute good increases, the demand for the other good will:
A) Decrease
B) Increase
, Page 4 of 47
C) Remain unchanged
D) Become perfectly inelastic
Correct Answer: B
Substitutes are consumed in place of each other; higher price of one makes the other relatively
cheaper, increasing its demand. Option A would be for complements.
8: The equilibrium price in a market is determined by:
A) The intersection of supply and demand curves
B) Government regulation only
C) The highest price consumers are willing to pay
D) The lowest price producers are willing to accept
Correct Answer: A
Equilibrium occurs where quantity demanded equals quantity supplied, graphically the
intersection of curves. Government may set prices but market equilibrium is intersection; C and
D are limits, not equilibrium.
9: A surplus exists in a market when:
A) Quantity demanded exceeds quantity supplied
B) Quantity supplied exceeds quantity demanded at the current price
C) Price is below equilibrium
D) Government imposes a price ceiling
Correct Answer: B
Surplus is excess supply (Qs > Qd). Option A is shortage; C causes shortage; D creates shortage
if below equilibrium.
10: The price elasticity of demand measures:
A) How responsive quantity demanded is to a change in price
B) How responsive price is to a change in quantity demanded
C) The slope of the demand curve
D) The change in total revenue when price changes
