Note that with the fall in price we have reduced the consumers money income by compensating variation in income so that he remains on the same indifference curve as before. If consumers' income drops, decreasing their ability to buy corn, demand will shift left (D3). . If the price of good X falls, price of Y remaining constant, the quantity demanded of good X will increase due to the substitution effect and income effect (we suppose that good X is not an inferior good).
