2. A basket of goods in 1987 cost $783, while the value of the same basket in 1997 was $1133. The value of
thisprice index in 1997, based on 1987 = 100, was:

b) multiplying the nominal value by the price level.
c) dividing the nominal value by the price index.
d) subtracting the price level from the nominal value and multiplying by 100.
4. In the figure above, if there is a shortage of 40 units, what does this mean?
a) Price will fall.
b) Price must be $8.
c) The quantity traded is 40.
d) Buyers would be willing to pay an additional $4 per unit for the quantity that they are now buying.
5. In the figure above, assume that the market was at equilibrium and that demand increases by 20 units. What
willbe the new equilibrium price and quantity?
a) Price will rise by $2 and quantity traded will rise by 20 units.
b) Price will fall by $2 and quantity traded will fall by 20 units.
c) Price will rise by $1 and quantity traded will rise by 10 units.
d) Price will fall by $1 and quantity traded will fall by 10 units.
6. If goods J and K are substitutes, an increase in the price of J causes:
a) quantity demanded of J to fall and the demand curve for K to shift toward the origin.
b) a decrease in quantity demanded for J and an outward shift of K's demand curve.
c) quantity demanded of J remains constant, but the demand for K decreases.
d) the demand curve for both J and K shift.
7. Assume that spinach is a normal good. Assume further that medical research has proven that eating spinach
willreduce risks of cancer. Due to economic recession:
a) there will be a leftward shift of the demand curve.
b) there will be a rightward shift of the demand curve.
2
, c) the demand curve may remain the same or may shift to the right or may shift to the left.
d) there will be lower price of spinach.
8. We can say with certainty that a rise in the minimum wage will increase the total dollar earnings of those
workersaffected by it if
a) the demand for labor is elastic.
b) the demand for labor is inelastic.
c) the supply of labor is elastic.
d) the supply of labor is inelastic.
9. An improvement in overall technology that allows more output to be produced with the same inputs causes:
a) a movement up the supply curve, resulting in both a higher equilibrium price and quantity.
b) a leftward shift of the supply curve so that less is offered for sale at every price.
c) no movement of the supply curve but a fall in price and an increase in quantity supplied.
d) a rightward shift of the supply curve so that more is offered for sale at every price.

11. Use the production possibilities described in the table above, the cost of each additional film in terms of food:
a) remains constant.
b) falls as more films are produced.
c) increases as more films are produced.
