Two graphs showing the substitution effect of a decrease in the price of x and the income effect of a decrease in the price of x.

Income and substitution effect normal good price increase. The price of x increases causing the budget line to shift from b1 to b2. The substitution effect measures how much the higher price encourages consumers to buy different goods assuming the same level of income. Thus the negative income effect de of the fall in the price of good x strengthens the negative substitution effect bd for the normal good so that the total price effect be is also negative that is a fall in the price of good x has led on both counts to the increase in its quantity demanded by be.

The consumer changes his consumption from the bundle of x and y represented by point a to the bundle represented by point b. Income effect and substitution effect are the components of price effect i e. In case of normal goods both the income effect and substitution effect move in the same direction.

However if x were an inferior good then the income effect would be negative. Income effect arises because a price change changes a consumer s real income and substitution effect occurs when consumers opt for the product s substitutes. The substitution effect also led to an increase in consumption of bread. This states that an increase in the price of a good will encourage consumers to buy alternative goods.
