Apple juice and orange juice are substitutes for consumers, so the fall in the price of apple juice decreases the demand for orange juice. The demand curve for orange juice shifts leftward. The increase in the wage rate paid to orange grove workers raises the cost of producing orange juice. The supply of orange juice decreases and the supply curve of orange juice shifts leftward. The net effect of these events decreases the equilibrium quantity but has an undetermined effect on equilibrium price. If supply decreases by more than the demand, the shift in the
