With budget line AB, the consumer can have combination Q if he so desires, but actually he will not buy combination Q because X is now relatively cheaper than before. impact of a change in p2.

For this, a budget line GH has been drawn which passes through point Q. In the preceding only a change in p1 was considered. More detailed discussions on the Marshallian and the Hicksian demand relations and the Slutsky equation can be found in many standard economics textbooks; see … 0000001509 00000 n Let us explain the concept of cost-difference and Slutsky substitu­tion effect with a numerical example stated below: When the price of petrol is Rs. Business . The TE will depend on which effect is stronger. Merits and Demerits of Hicksian and Slutsky Methods: Prof. J.R. Hicks points out that the method of adjusting the level of money income by the compensating variation has the merit that on this interpretation, the substitution effect measures the effect of change in relative price, with real income constant, the income effect measures the, effect of the change in real income. As a result of the rise in price of X, bud­get line will shift downward to PL” and consumer’s real income or purchasing power of his given money income will fall. 9B.4. The difference between the two versions of the substitu­tion effect arises solely due to the magnitude of money income by which income is reduced or increased to compensate for the change in income. 0000060937 00000 n where the column vector on the right is represented in the With a fall in price of X, other things remaining the same, budget line shifts to PL2. The notation ( )y, ( )u and ( )P indicates that the This difference was later emphasised by J.R. Hicks, but since it was Slutsky who first of all split up the price effect into substitution effect and income effect the above equation is popu­larly known as Slutsky equation.

The general formula for Slutsky equation is given by. 17. A.10 Marshallian and Hicksian demand curves. Substitution effect: because it offers more utility per unit of money, other alternatives become less attractive. For this, a price line GH parallel to PL’ has been drawn which passes through the point Q. 9B.2. While separately discussing substitution effect above, we pointed out the merits and demerits of the Hicksian and Slutskian methods of breaking up the price effect. It is obtained from the derivative of the Hicksian demand with regards price. Rather than present those equations separately it is In other words, his money income must be increased to the extent which is just large enough to permit him to purchase the old combina­tion Q, if he so desires, which he was buying before. A Microeconomist’s View to Minimizing Costs within a Firm, Consumption Bundles, Utility, and Possible Sets, Microeconomics and the Importance of Decisions, By Lynne Pepall, Peter Antonioni, Manzur Rashid. startxref 9B.1 With a given money income and the given prices of two goods as represented by the price line PL, the consumer is in equi­librium at Q on the indifference curve IC1 buying OM of X and ON of Y. The equation showing how the effect on demand for a good of a change in a price can be decomposed into a substitution effect, which is the effect of a change in relative prices at an unchanged level of utility, and an income effect, which is the effect of a change in real income holding prices constant. partial derivatives with respect to p1 and are denoted as The first order conditions for the maximizing values of Thus, in case of rise in price of a good, both the substitution effect and also income effect (if it is a normal good) will work in the same direction to reduce the quantity demanded of the good whose price rises. Since, with the rise in price and simultaneous increase in his income equal to the cost-difference has enabled him to attain a higher indifference curve, he has become better off than before the rise in price. 0000042187 00000 n Denote the demand for good i by xi, the price of good j by pj, income by M, and utility by U. income y the result is: The second term in the equation for the effect of a change in p1. <<435B5D29C541504294DEE9A395B83DAE>]>> Thus the solution is A glance at Fig. x 1’ x 1’’ x 1 But actually he will not buy combination Q, since on budget line GH, X is relatively dearer than before, he will therefore replace some X by Y (i.e., he will substitute of Y for X).
