INCOME EFFECT: One of two reasons for the law of demand and the negative slope of the market demand curve (the other is the substitution effect). The income effect results because a change in price gives buyers more real income, or the purchasing power of the income, even though money or nominal income remains the same. This causes changes in the quantity demanded of the good.
