X as an Inferior Good.

The price effect is compounded of the substitution effect and the income effect which can be separated in two ways. This is used to detect comment spam. The Hicksian method of decomposing the price effect into the substitution and income effects is defective in that it lacks practical applicability because it is not possible to know exactly how much real income of the consumer should be changed in order to keep him on the original indifference curve.

Let us look at figure 1. Notify me of followup comments via e-mail. No data is shared with Facebook unless you engage with this feature. Get New Comparisons in your inbox: By the method of compensating variation in income, the real income of the consumer has increased as a result of the fall in the price of X. To isolate the substitution effect, the increased real income due the fall in the price of X is withdrawn from the consumer by drawling the budget line MN parallel PQ.

What we are doing here is that we make the consumer to purchase his sluysky consumption bundle i. Hence, the remaining change in quantity represents the change due to income effect.

In terms of the Slutsky method, a new budget line M 1 N 1 is drawn parallel to PQ 1 in such a way that the zpproach real income of the consumer remains the same even after the fall in the price of X. This occurs because of the price effect, which comprises income effect and substitution effect.

Similarly, a fall in the price of bread raises the real income of consumers who substitute expensive food item for bread appproach reducing the demand of bread.

When the price of one commodity falls, the consumer substitutes the cheaper commodity for the costlier commodity.

Separation of Substitution and Income Effects from the Price Effect

Is there any significance to this inherent difference between the Slutskian and Hicksian approaches when deriving the substitution effect? Differences between Hicksian and Slutskian approaches Ask Question. When X is an inferior good and its price falls, the substitution effect is greater than the income effect so that the consumer buys more of X when its price falls. Email Required, but never shown. Thus the relation between price and quantity demanded being inverse, the substitution effect of a price change is always negative, real income being held constant.


The case of X as an inferior good is illustrated Figure Top 2 Methods With Diagram. This is known as income effect. With the fall in the price of X when the real income of the consumer increases, it is adjusted in such a way that the consumer is in a position to have the same amount of X as before if he likes so that his apparent real income remains constant.

With that, the demand for several products has increased. The movement of the consumer from point R to T or from A to D on the horizontal axis is the price effect.

Post as a guest Name.

The Slutsky substitution effect provides the consumer greater satisfaction by bringing him on a higher indifference curve, while the Hicksian substitution effect brings him back to the initial level of satisfaction on the original indifference curve.

On the other hand, the Slutsky substitution effect tells that with the fall in the price of good X, the consumer spends his increased income in such a manner as to buy the original quantities of A and Y if he so desires and there is no change in his apparent real income. No data is shared unless you engage with this feature. The movement from point R to H on the I 1 curve measures the substitution effect.

The Slutsky Equation is also termed as the Slutsky Identity. However, since people are searching for cheaper brands, approavh prices of computers have also decreased. Home Questions Tags Users Unanswered. To isolate the income effect, when the income, which was taken away from the consumer, is returned to him, he moves from point H to T so that he reduces the consumption of X by a very large quantity DE.

Suppose X is a Giffen good and the initial equilibrium point is R where the budget line PQ is tangent to the indifference yicksian I 1. We get the income effect by subtracting substitution effect X 1 X 3 from the total price effect X 1 X 2. This is the negative substitution effect which leads him to buy BD more of X with the fall in its price, real income being constant.

Let s,utsky price of good X fall.

In Slutsky slutssky, the substitution effect leads the consumer to a higher indifference wnd. This is due to changes in the relative prices of X and Y so that the increased real income of the consumer is spent in such a manner that he is neither better off nor worse off than before.

The reason for such a paradoxical tendency is that when the price of some food articles like bread of mass consumption rises, this is tantamount to a fall in the real income of the consumers who reduce their expenses on more expensive food items, as a result the demand for the bread increases. This income effect is positive because the fall in the price of the inferior good X leads, via compensating variation in income, to the decrease in its quantity demanded by DE. This fact has been classified by both the methods.

When you hold the real income constant, you will be able to measure the change in quantity caused due to substitution effect. Meaning and Assumptions With Diagram. An increase in the quantity demanded of commodity X is hicksiaan by both income effect and substitution effect. This is the positive income effect because with the fall in the price wlutsky the Giffen good X, its quantity demanded is reduced by DE via compensating variation in income.

There is no need to resubmit your comment. In figure 3, AB 1 is the initial budget line. This microeconomic equation was named after Eugen Slutsky. In Figure 37, the movement of the consumer from R to T or A to D on the horizontal axis is the price effect from the points of view of Hicks and Slutsky.
