Resources X and Y are substitutes in production, and resources X and Z are complements in production. Which of the following will most likely lead to a fall in the price of X? A(an):
A) decrease in the price of Y and an increase in the price of Z.
B) increase in the price of Y and an increase in the price of Z.
C) decrease in the price of Y and a decrease in the price of Z.
D) increase in the price of Y and a decrease in the price of Z.
The correct answer was A) decrease in the price of Y and an increase in the price of Z.
If X and Y are substitutes, then a fall in the price of Y will lower the demand for X and lower its price. An increase in the price of Z, which is used with X, will lower the demand for X and lower its price. In each of the other pairs of events in the other answers, at least one of the pairs will give upward pressure on the price of X.
