Income effect and substitution effect are the components of price effect i e.
Income and substitution effect normal good price decrease. The income effect expresses the impact of higher purchasing power on consumption. The substitution effect describes how consumption is impacted by changing relative income and prices. 12 we show that the substitution effect is stronger than the income effect. If the price of a normal good rises the income effect a.
Will decrease consumption of the good and the substitution effect will increase its consumption. Since income is not a good in and of itself it can only be exchanged for goods and services price decreases increase purchasing power. The income effect is the change in consumption patterns due to a change in purchasing power. 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.
Normal good decrease in price of good x a b c e 1 e 2 e starting point ending point imaginary point substitution effect 6 starting point imaginary point income effect 7 imaginary point ending point total effect 13 starting point ending point. However if x were an inferior good then the income effect would be negative. Thus in case of normal goods both the income effect when positive and negative substitution effect work in the same direction and cause increase in the quantity purchased of good x whose price has fallen with the result that the new equilibrium point will lie to the right of the original equilibrium point q such as point r in fig. The consumer s equilibrium is at point 1.
This occurs with income increases price changes and even currency fluctuations. The decrease in quantity demanded due to increase in price of a product.
