8.7. The point A (Y1 Y2) lies on both the lines. This website uses cookies and third party services. Account Disable 12. Since, at the optimum point or the point of tangency, the numerical slope of the IC is equal to that of the budget line, and since, the former is equal to MRS of C) for C2 and the latter is equal to 1 + r, the consumers optimum or equilibrium point is characterised by: MRC1 for C2 = 1 + r (6.35). It is the locus of points representing pairs of quantities between which the individual is indifferent, so it is termed an indifference curve. It is, in fact, an iso-utility curve showing equal satisfaction at all its points. 6.101. This is what is expected, because the imposition of the tax has caused an increase in the price of one of the two goods, viz., X, that the consumer buys. Uploader Agreement. 11.20 where in panel (a) wage offer curve is shown, and in panel (b) supply curve of labour is drawn corresponding to leisure-work equilibrium points in panel (a)Thus, to start with at wage rate w0 (i.e. We take a situation when the subsidy is not paid in money but the consumers are supplied cereals at concessional rates, the price-difference being paid by the government. As we know, the movement of the consumers equilibrium point from D to E represents the total effect of the rise in r. We may break up this effect into an IE and an SE. Content Guidelines 2. How to Derive Indifference Curves through Revealed Preference Approach. 6.100. Account Disable 12. Hicks consider this inadequate and explain them after making compensating variation in income. Property II: Indifference curves are convex to the origin: Another important property of indifference curves is that they are usually convex to the origin. For example, Figure 1 presents three indifference curves that represent Lilly's preferences for the tradeoffs that she faces in her two main relaxation activities: eating doughnuts and reading paperback books. The degree of convexity of an indifference curve depends on the rate of fall in the marginal rate of substitution of X for Y. If the interest rate is zero (r = 0), total consumption in the two periods equals total income in the two periods: (Q + C2 = Y1 + Y2). 6.103 that the total effect of the rise in r is equal to the SE plus the IE. But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction. Plagiarism Prevention 5. The consumers preferences regarding consumption in the two periods can be represented by his indifference curves (ICs). After we have known the SE, we may now restore the improvement in the real income of the consumer by giving him back the curtailed portions of Y1 and/or Y2. 6.96(b), (c) and (d) the consumer will never be worse off and sometimes he will be better off, as in the case of Fig. It tells us the rate at which period 1 consumption would be substituted for period-2 consumption at any particular point on the IC, or, at any particular C1. The downward slope of the indifference curve means that Lilly must trade off less of one good to get more of the other, while holding utility constant. The prices of the goods X and Y are fixed for the consumer. 4.3 Indifference Curves are convex to the origin. 4 Important Properties of Indifference Curve (with curve diagram) - - StuDocu. Uploader Agreement. Here is an example to understand the indifference curve better. We have concluded that an individual consumer will always prefer cash subsidy to an in-kind subsidy. It Provides a Better Classification of Goods into Substitutes and Complements and Others. However, they can, and do, identify what choices would give them more, or less, or the same amount of satisfaction. But the purpose of the Edgeworth box is not to illustrate the price fixing which can take place when there is no . The utility analysis assumes constant marginal utility of money. It means that it cannot be efficient to have total consumption of any good which is less than the output of the good. As will be seen in Fig. He has moved from a higher IC (IC2) to a lower IC (IC1). Content Filtration 6. Examples of Indifference Curve with Diagram. As a result, the consumers budget line would have a parallel leftward shift from L2M2 to ST, the latter being a tangent to IC1 at the point F (C1 C2). (3) The consumer possesses complete information about the prices of the goods in the market. At point D, the consumer plans to consume nothing in period 2 (C2 = 0) and he borrows in period-1 as much as possible against period-2 income. The consumer likes all of them equally. To understand why higher indifference curves are preferred to lower ones, compare point B on indifference curve Um to point F on indifference curve Uh. As a result, there would be an outward parallel shift in the budget line. They may represent higher or lower satisfaction of the consumer. In the case of a cash subsidy the consumer is given some amount of cash as a matter of subsidy. As we know, the movement in the consumers equilibrium point from D to F along IC1 is due to the SE. Privacy Policy 9. But Fishers model says, instead, that consumption is based on the resources the consumer expects to have over his lifetime. A higher indifference curves to the right of another represents a higher level of satisfaction and preferable combination of the two goods. As one moves along a straight-line indifference curve of perfect substitutes, marginal rate of substitution of one good for another remains constant. Uploader Agreement. For example, Figure 1 presents three indifference curves that represent Lillys preferences for the tradeoffs that she faces in her two main relaxation activities: eating doughnuts and reading paperback books. We shall first discuss the saving case with the help of Fig. If period-1 consumption is less than period-1 income, the consumer is saving (S > 0). Along with the budget line are shown the three indifference curves from Figure 1. The relevant Lagrange function for constrained maximization of the (1) subject to (5) is, The 1st order conditions for constrained maximization of U is. Indifference Curve Applications: Income Tax vs. Period 1 represents the consumers youth and period 2 represents the consumers old age. Let us note that his consumption of X is higher under the income tax than under the excise tax (GE > FD), since, under the excise tax, he is at the point D, but under the income tax, he has further opportunity to maximise in the region of the triangle DB1B2. At point B, the consumer consumes nothing in period 1 (Q = 0) and saves all income, so the period-2 consumption is C2 = (1 + r) Y1 + Y2. The ordinal method and the assumption of transitivity make this technique more realistic. Property IV: A higher indifference curve represents a higher level of satisfaction than a lower indifference curve: The last property of indifference curve is that a higher indifference curve will represent a higher level of satisfaction than a lower indifference curve. 8.8. It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. The better substitutes the two goods are for each other, the closer the indifference curve approaches to the straight line so that when the two goods are perfect substitutes the indifference curve is a straight line. We may explain the matter with the help of Fig. Pen and ink, right shoe and left shoe, automobile and petrol sauce and hamburger, type writer and typists are some examples of perfect complements. In other words, the combinations which lie on a higher indifference curve will be preferred to the combinations which lie on a lower indifference curve. 6.102, from C1 to C and his C2 would increase from C2 to C2. Content Filtration 6. First, the case in which the consumer is initially saving, and second, the case in which he is initially borrowing. This line has touched one of his ICs, viz., IC1 at the point D(C1, C2). The point A (Y1, Y2) lies on the budget line L1M1. By joining these points we obtain the IC. Since an infinite number of indifference curves exist, even if only a few of them are drawn on any given diagram, there will always exist one indifference curve that touches the budget line at a single point of tangency. The entire utility analysis assumes that utility is a cardinally measurable quantity which can be assigned weights called untils. The reason behind this shape involves diminishing marginal utilitythe notion that as a person consumes more of a good, the marginal utility from each additional unit becomes lower. Therefore, the consumer will be indifferent between the two types of subsidy. Only convex curves will lend to the principles of Diminishing Marginal Rate of substitution. In order to isolate the SE, we shall for the time being compensate the consumer for the deterioration in his real income level by appropriately increasing his Y1 and/or Y2, r remaining unchanged. The indifference curve technique explains consumers equilibrium in a similar but better way than the Marshallian proportionality rule. We may verify in Fig. We may conclude, therefore, that the consumer is better off with a cash subsidy than with a selective price subsidy on a single good. These questions allow you to get as much practice as you need, as you can click the link at the top of the first question (Try another version of these questions) to get a new set of questions. Lastly, in Fig. 6.96 that the effects of the two types of subsidy would depend upon the preference-indifference pattern of the consumer, i.e., upon the position of his indifference curves (ICs). The indifference curve technique is a two-commodity model which discusses consumer behaviour in the case of substitutes, complementaries and unrelated goods. He regards consumers surplus as a means of expressing, in terms of money income, the gain which accrues to the consumer as a result of a fall in price. Thus the doctrine of consumers surplus is no longer a mathematical puzzle and has been freed from the introspective cardinalism of the utility theory. In microeconomics, indifference curve is an important tool of analysis in the study of consumer behavior. So period-1 consumption would be C1 = Y1 + Y2/1+r. Most people would prefer to increase the quantity or quality of the goods and services they consume. The consumers equilibrium point now would move from the point D (C1, C2) on IC2 to the point E(C, C) on a lower IC, viz., IC1, indicating that the consumers real income has decreased. If, for instance, the amount of good X is increased in the combination, while the amount of good Y remains unchanged, the new combination will be preferable to the original one and the two combinations will not therefore lie on the same indifference curve provided more of a commodity gives more satisfaction. This is the income effect. Disclaimer 8. An indifference curve is a line showing all the combinations of two goods which give a consumer equal utility. Because of the shape of the consumers ICs and that of his budget constraint, he would achieve the highest possible level of satisfaction at c, the point of tangency between his budget line and one of his ICs. Combination Q has been taken on a higher indifference curve IC2 and combination S on a lower indifference curve IC1. The consumption function introduced by Keynes (1883-1946) relates current consumption to current income. It is untainted by the psychological assumptions of the utility analysis. All lower indifference curves, like Ul, will cross the budget line in two separate places. It Studies Combinations of Two Goods Instead of One Good 3. This would result in a substitution effect (SE). Here the initial optimum point of the consumer is Q1 and the new equilibrium point after a parallel outward shift of the budget line is Q2. Fig. In the following schedule (Table 1), the consumer is indifferent whether he buys the first combination of units of 18Y+1 unit of X or the fifth combination of 4 units of Y+5 units of X or any other combination. (8) An indifference curve is always convex to the origin. The concept of indifference curve analysis was first propounded by British economist Francis Ysidro Edgeworth and was put into use by Italian economist Vilfredo Pareto during the early 20 th century. An IC here is negatively sloped. (6) He prefers more of X to less of Y or more of Y to less of X. Economists use the vocabulary of maximizing utility to describe consumer choice. The meeting of two indifference curves at a point will also lead us to an absurd conclusion.

Uploader Agreement. Watch the clip from this video carefully to see examples of indifference curves and what makes them useful. Consider an individual whose utility function is U = C1C2, where Ct and C2 represent present and future consumption respectively. Let us also note that the variable S can represent either saving or borrowing (negative saving) and equations (6.131) and (6.132) hold in both cases. Hence the name indifference curve. This website uses cookies and third party services. 8.5 two indifference curves are shown cutting each other at point C. Now take point on indifference curve IC2 and point B on indifference curve IC1 vertically below A. 6.99 shows two of the consumers many ICs. In period 1, saving equals income minus consumption, i.e.. Did you have an idea for improving this content? Each point on an indifference curve indicates that a consumer is indifferent between the two and all points give him the same utility. 6.99 are not straight lines. Let us now come to the effects of an income tax upon the economic well-being of the consumer. Each indifference curve (Ul, Um, and Uh) represents one level of utility. Nederlnsk - Frysk (Visser W.), Handboek Caribisch Staatsrecht (Arie Bernardus Rijn), The Importance of Being Earnest (Oscar Wilde), English (Robert Rueda; Tina Saldivar; Lynne Shapiro; Shane Templeton; Houghton Mifflin Company Staff), Auditing and Assurance Services: an Applied Approach (Iris Stuart), Managerial Accounting (Ray Garrison; Eric Noreen; Peter C. Brewer), Junqueira's Basic Histology (Anthony L. Mescher), Big Data, Data Mining, and Machine Learning (Jared Dean), Principles of Marketing (Philip Kotler; Gary Armstrong; Valerie Trifts; Peggy H. Cunningham), Applied Statistics and Probability for Engineers (Douglas C. Montgomery; George C. Runger). The indifference curve analysis measures utility ordinally. The amount of cash subsidy here is BB1.px, or, AA1.py. The better substitutes the two goods are for each other, the closer the indifference curve approaches to the straight-line so that when the two goods are perfect substitutes, the indifference curve is a straight line. Meaning of Indifference Curve 2. This constraint can be easily interpreted. As stated above, when two goods are perfect substitutes of each other, the indifference curve is a straight line on which marginal rate of substitution remains constant. The indifference curve I 1 is the locus of the points L, M, N, P, Q, and R, showing the combinations of the two goods X and Y between which the consumer is indifferent. As some amount of a good has to be sacrificed for an additional unit of another good it is the Opportunity Cost. In Figure 3, consider the indifference curves f and I 2 and combinations N and A respectively on them. People cannot really put a numerical value on their level of satisfaction. The Marginal Rate of Substitution is the amount of of a good that has to be given up to obtain an additional unit of another good while keeping the satisfaction the same. An increase in Y1 and/or Y2, r remaining unchanged, leads to a rise in both the intercepts of the budget line, viz., Y1 + (Y2/1+r) and (1 + r) Y1 + Y2, the slope of the budget line remaining the same. This website uses cookies and third party services. Home; Company; Products. This is because the consumer is a borrower in period 1 and r has increased. Copyright 10. 6.102. At this point, the slope of the indifference curve equals the budget line, so that. It happens in the case of those inferior goods whose income effect exactly equals substitution effect. Indifference curves like Um are steeper on the left and flatter on the right. The indifference curve technique is a two-commodity model which discusses consumer behaviour in the case of substitutes, complementaries and unrelated goods. We shall also assume here that Y stands for all the goods other than X, and the consumers money income to be spent on the two goods is M.
