Substitution And Income Effect Price Increase

Thus the slutsky s substitution effect is derived when the income adjustment is such that the consumer can buy the old bundle at the new set of prices.

Substitution and income effect price increase. Hicks has explained the substitution effect independent of the income effect through compensating variation in income. The substitution effect is the increase in the quantity bought as the price of the commodity falls after adjusting income so as to keep the real purchasing power of the consumer the same as before. Income effect and substitution effect are the components of price effect i e. When the price of an inferior commodity falls the substitution effect leads to an increase in the quantity demanded whereas the income effect reduces the quantity demanded.

The negative substitution effect outweighs the whole negative income effect. In the sulstky method the increased income due to fall in price is adjusted or compensated so that the consumer can be on the original or the old indifference curve at the new set of prices. The income effect expresses the impact of increased purchasing power on consumption while the substitution effect describes how consumption is impacted by changing relative income and prices. 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.
