Figure 3-8
The graph in this figure illustrates an initial competitive equilibrium in the market for
apples at the intersection of D2 and S2 (point E). Which of the following changes would
cause the equilibrium to change to point A?
A) A positive change in the technology used to produce apples and decrease in the price
of oranges, a substitute for apples.
B) An increase in the wages of apple workers and a decrease in the price of oranges, a
substitute for apples.
C) An increase in the number of apple producers and a decrease in the number of apple
trees as a result of disease.
D) A decrease in the wages of apple workers and an increase in the price of oranges, a
substitute for apples.
Better health allows people to work harder, which raises a country’s total income. This
indicates that in effect, better health
A) is a primary cause of price increases.
