If the total satisfaction is to remain the same, the consumer must part with a diminishing number of bananas as he gets as increasing stock of oranges. Thus, his preferences are such that rationing is not actually binding for him. Plagiarism Prevention 4. We therefore conclude that indifference curves cannot cut each other. Consumer goods companies and the industry offer a vast range of products that heavily contribute to the global economy. It provides equivalent satisfaction and utility levels for the consumer. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. The loss of satisfaction to the consumer on account of the downward movement must be made up by the gain through the rightward movement. Combinations of two goods on the curve provide Jack with the same level of satisfaction (represented by points A, B, C, D in the image). This cookie is set by GDPR Cookie Consent plugin. A single indifference curve concerns only one level of satisfaction. If a tangency point is reached between the indifference curve and budget line then you do not have a corner . You also have the option to opt-out of these cookies. Therefore, this can be interpreted to be the case of a poor family whose optimum consumption basket of the two goods is small because of its low income and therefore remains unaffected if ration limits are set at higher levels. Likewise, when the wage rate rises to w2 (w2, = OM2/ OT), income-leisure line shifts to TM2 the individual chooses to have leisure time OL2 and supplies TL1 work-hours. Though the consumer can buy the ration amount, that is, ration limit is attainable but he is not willing to consume good X as much as the ration limit permits him. A higher indifference curve shows a higher level of satisfaction. 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. If the graph is on the curve or line, then it means that the consumer has no preference for any goods, because all the good has the same level of satisfaction or utility to the consumer. Assumes marginal rate of substitution to diminish. Though both the lump-sum cash transfer and price subsidy on a commodity produces income effect making the individual better off, under cash grant the individual is free to buy different goods according to his own tastes and preferences which ensures a higher level of welfare as compared to the policy of price subsidy on food which imposes a certain pattern of consumption favouring food. These cookies will be stored in your browser only with your consent. On the other hand, in case of good, case of good X in Figure 11.10 the ration limit Rx does not seem to be effective, though it is potentially binding as it truncates his market opportunity set. The indifference curve I1 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. Here, of course, is a special case of general principle that, apart from considerations of etiquette and sentiments, you can make someone happier if you give him cash instead of a commodity even if the commodity is something he wants. Income Effect and Substitution Effect of the Change in Wage Rate: Now the supply curve of labour does not always slope upward as is shown in Fig. The indifference curve analysis measures utility ordinally. It provides equivalent satisfaction and utility levels for the consumer. 2. Introduction of rationing limits forces him to come to point K on the lower indifference curve IC0 and consume less amounts of both the goods than he would do without the restriction of rationing. It will be observed that binding by rationing lowers his level of welfare as he is forced to come to the point L on a lower indifference IC0 where he consumes less of good Y and more of good X than he prefers. Prohibited Content 3. An indifference curve is a curve that represents all the combinations of goods that give the same satisfaction to the consumer. If the graph is on the curve or line, then it means that the consumer has no preference for any goods, because all the good has the same level of satisfaction or utility to the consumer. This means for most of the recipients, food stamp programme has the same effect as a cash subsidy. 8.8 two perfect complements are consumed in the ratio, 3X: 27. An indifference curve reveals many combinations of two goods a consumer prefers to consume. 4 Important Properties of Indifference Curve (with curve diagram) - - StuDocu. Here we discuss the properties of the indifference curve and how to analyze it, along with examples and assumptions. As in case of change in price, rise in wage rate has both the substitution effect and income effect. But it should be noted that in the second possible case the consumption of food is more under the food stamp subsidy programme than, in case of cash subsidy. It will be seen from Figure 11.19 that TM0 is tangent to indifference curve IC1 between leisure and income at point R. Thus, with wage rate w0the individual is in equilibrium when he enjoys OL0 leisure and therefore he is supplying TL0 work hours of labour. While each axis denotes a different form of consumer goodsConsumer GoodsConsumer goods are the products purchased by the buyers for consumption and not for resale. In the above image, the combination outside the budget line (S) represents the one beyond the income. Image Guidelines 5. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. And this indifference in prices defines the opportunity costs. Higher indifference curve represents larger bundles of goods i.e. He decides to exchange 4 units of books for an additional piece of cloth. Thus the indifference curve I4 indicates a higher level of satisfaction than I3 which, in turn, is indicative of a higher level of satisfaction than I2 and so on. For instance, the aim of Governments food subsidy programme may be that the needy families should consume more food so that their health and efficiency may be improved. In panel (a) of this figure it will be seen that at the wage rate w0(w0= OM0/OT), the wage line or income-leisure line is TM0 and the individual is in equilibrium at point Q where he chooses OL0 leisure time and works for TL0 hours. When a consumer wants to have more of a commodity, he/she will have to give up some of the other commodity, given that the consumer remains on the same level of utility at constant income. Disclaimer 9. Indifference curve must be convex to the origin: goods other than food). 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. Required fields are marked *. Prior to grant of any subsidy, and given his budget line B1L1 the individual is in equilibrium at point E1 on indifference curve IC1. Since A is on a higher . Thus, the slope of the income-leisure curve OM/OT equals the wage rate. In this article we will discuss about Indifference Curves. (4) The prices of the two goods are given. One possibility is that with the food-stamp subsidy and resultant kinked budget line B1CL2, in Fig. If the various combinations are plotted on a diagram and are joined by a line this becomes an indifference curve, as f in the Figure 1. However, the more important and relevant case of rationing is depicted in Figure 11.8. "Nothing is more important than my child's safety" is a corner solution in its refusal to admit there might be trade . But the above principle regarding the programme of subsidised food, subsidised housing etc. In India also food stamp programme has been suggested in recent years as an anti-poverty measure. We also use third-party cookies that help us analyze and understand how you use this website. When no price subsidy is paid, the individual faces the price line PL1. Privacy Policy3. As a result of the rise in price of good X, the price line rotates to a new position PL2 which is tangent to indifference curve IC1 at point Q1. In Fig. Now, the important question is what is the money value of this price subsidy (RM) on food to the individual. With a given income of the individual and the given price of good X, the price line is PL1 which is tangent to indifference curve IC3 at point Q3 where the individual is in equilibrium position. We shall explain below only few applications. It will be seen from Figure 11.16 that the given income-leisure line MT is tangent to the indifference curve IC2 at point E showing choice of OL1 of leisure and OM1 of income. A normal indifference curve will be convex to the origin and it cannot be concave. Consumer Surplus = Maximum Price to be paid willingly Actual Paid Price The indifference curve shows that she could obtain the same level of utility by moving to point W, skiing for 7 days and going horseback riding for 1 day. Consumer Surplus is the difference between the actual price that the customers pay for a product & the maximum price that they are ready to pay (for a single unit). Thus, if a person chooses combination C, this means that he has OL1 amount of leisure time and OM1 amount of income. Irish-born British economist Francis Ysidro Edgeworth first proposed this two-dimensional graph, also known as the iso-utility curve. Combination Q on the higher indifference curve IC2 will give a consumer more satisfaction than combination S on the lower indifference curves IC1 because the combination Q contains more of both goods X and Y than the combination S. Hence the consumer must prefer Q to S. And by transitivity assumption, he will prefer any other combination such as combination R on IC2 (all of which are indifferent with Q) to any combination on IC1 (all of which are indifferent with S) We, therefore, conclude that a higher indifference curve represents a higher level of satisfaction and combinations on it will be preferred to the combinations on a lower indifference curve. When it occurs, it is known as the marginal rate of substitution (MRS). Complements are thus those goods which are used jointly in consumption so that their consumption increases or decreases simultaneously. Now, suppose that instead of excise duty, Government levies a direct tax of the type of lump-sum tax on the individual when the individual is initially at point Q3 on indifference curve IC3. number of hours worked). This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. Your email address will not be published. He is in equilibrium at point E where he consumes quantity of good X which is smaller than the ration amount Rx. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. Therefore, RM is also greater than PE. Supply curve of labour shows how an individuals work effort responds to changes in the wage rate. Consider indifference curves IC1 and IC2 in Fig. This is a substitution effect of the rise in wage rate tends to reduce leisure and increase labour supply (i.e. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. This is an important feature of Indifference Curve. At the old price (before the excise duty was imposed), he could purchase ON quantity of good X for PT amount of money. If the Government provides the consumer lump-sum cash grant of RM instead of price subsidy on food, this will amount to increasing the money income of the consumer by RM amount. If a consumer purchases two goods, the budget limitation can be displayed with the help of a budget line on a graph. Thus, indirect tax (excise duty) causes an excess burden on the individual. Another point which is worth mentioning in this regard is that indifference curves cannot even meet or touch each other or be tangent to each other at a point. Suppose now that Government levies an excise duty (an indirect tax) on good X. The curve slopes downward as the consumption of commodity A increases in exchange for commodity B. You also have the option to opt-out of these cookies. 11.4 . Consumers would prefer to move in the direction indicated by the arrow in the figure. This is because cash subsidy does not limit a person that he must purchase certain amount of food and is therefore free to spend as he likes. It will be seen from Figure 11.1 that PE is less than RM which is the amount of money paid by the Government as subsidy. It is worth noting that price subsidy on a commodity is also generally called excise subsidy. The slope of the indifference curve measuring marginal rate of substitution between leisure and income (MRSLm ) shows the tradeoff between income and leisure. The imposition of a lump-sum tax (or any income tax) does not affect the prices of goods because it is not levied on any saleable goods. First, he is free to work as many hours per day as he likes. Share Your PDF File But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction. It may be noted that income of a consumer along with the prices of goods serves as a constraint on his choices and is often called a budget constraint. It should be further noted that at point Q1 (that is, after the imposition of excise duty) the individual is purchasing ON amount of good X and has paid PM amount of money for it. Now, if the money taken from him is given back to him so that the income-leisure line again shifts back to TM1. Now, we can bring together the indifference map showing ranking of preferences of the individual between income and leisure, and the income-leisure line to show the actual choice of leisure and income by the individual in his equilibrium position. How the effect of rise in wage rate is split up into income effect and substitution effect is shown in Fig. At the extreme, when two goods cannot at all be substituted for each other, that is, when the two goods are perfect complementary goods, as for example gasoline and coolant in a car, the indifference curve will consist of two straight lines with a right angle bent which is convex to the origin as shown in Fig. Share Your Word File The individuals preferences between food and other goods are such that with this cash subsidy the individual is in equilibrium at point H where the budget line B2L2 is tangent to his indifference curve IC3. An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. Second, wage rate is the same irrespective of the number of hours he chooses to work. It Provides a . 200 per week which he can spend on food alone. The excise duty, sales tax are the examples of indirect tax. Some of the important problems are explained below with the help of this technique. It is important to note that in this possible case, the effect of food stamp subsidy is exactly the same as would be the case if cash subsidy is granted to the individual. The cookies is used to store the user consent for the cookies in the category "Necessary". It follows that PE is less than RM. In Figure 6, consider the indifference curves I 1 and I 2 and combination N and A respectively on them. When the wage rate rises to W1 (budget constraint becomes TM1 in panel (a) of Fig. The degree of convexity of an indifference curve depends upon the rate of fall in the marginal rate of substitution of X for Y.
