The substitution effect refers to the change in consumption patterns that occurs when a price change makes one good relatively cheaper than another, leading consumers to substitute one for the other.
Among the provided statements, the best one that describes the substitution effect is:
As wages increase, an individual's leisure becomes more costly, making him less likely to choose leisure over labor. As the price of Coca Cola rises consumers purchase more Sprite.
This statement captures the essence of the substitution effect in two parts: the idea that as the opportunity cost of leisure increases (due to higher wages), individuals may choose to work more (substituting labor for leisure), and the example of consumers switching from Coca Cola to Sprite when the price of Coca Cola increases, illustrating the substitution effect in consumption.
