A fall in the price of X must tend to increase the consumption of X (by the first substitution theorem); if it increases the consumption of Y and there are no other goods in the budget, the consumer will have moved to a position in which case he has more Y and no less X; by the consistency theory this cannot be indifferent with his initial position. However, in order to prevent him from gaining in real income his money income is reduced large enough to keep him on the same indifference curve, he will buy less than Ox2 quantity of the commodity.
