The increase will cause the budget line to pivot from BC1 to BC2. Also, the indifference curve will shift from I1 to I2. This represents a movement to a higher indifference curve. The equilibrium position is the point of tangency between the budget line and the indifference curve. When the price of commodity Y falls, a consumer will be indifferent between consumption at point A and B because they lie on the same indifference curve. However, at point B, the consumer shall not have exploited Continue reading
