Consider the Market for Grapes

Consider the market for grapes. An increase in the wage paid to grape pickers will cause the:

A) demand curve for grapes to shift to the right, resulting in a higher equilibrium price for grapes and a reduction in the quantity consumed.
B) demand curve for grapes to shift to the left, resulting in a lower equilibrium price for grapes and an increase in the quantity consumed.
C) supply curve for grapes to shift to the right, resulting in a lower equilibrium price for grapes and an increase in the quantity consumed.
D) supply curve for grapes to shift to the left, resulting in a higher equilibrium price for grapes and a decrease in the quantity consumed.
