question
Refer to the diagram. A price of \$20 in this market will result in a:
shortage of 100 units.
question
Refer to the diagram, which shows demand and supply conditions in the competitive market for product X. If supply is S1 and demand D0, then
0F represents a price that would result in a shortage of AC.
question
Refer to the diagram, in which S1 and D1 represent the original supply and demand curves and S2 and D2 the new curves. In this market the indicated shift in demand may have been caused by:
an increase in incomes if the product is a normal good.
question
Refer to the table. If demand is represented by columns (3) and (1) and supply is represented by columns (3) and (4), equilibrium price and quantity will be:
\$9 and 60 units.
question
Refer to the diagram. An increase in quantity supplied is depicted by a:
move from point y to point x
question
If products A and B are complements and the price of B decreases, the:
demand for A will increase and the quantity of B demanded will increase.
question
Refer to the diagram, which shows demand and supply conditions in the competitive market for product X. Other things equal, a shift of the supply curve from S0 to S1 might be caused by a(n):
increase in the wage rates paid to laborers employed in the production of X
question
Refer to the diagram, in which S1 and D1 represent the original supply and demand curves and S2 and D2 the new curves. In this market:

question
The demand curve shows the relationship between:
price and quantity demanded.
question
Assume in a competitive market that price is initially above the equilibrium level. We can predict that price will:

question
Refer to the diagram, which shows demand and supply conditions in the competitive market for product X. Given D0, if the supply curve moved from S0 to S1, then:
supply has decreased and equilibrium quantity has decreased
question
