It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. 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. To break up this wage effect on labour supply, we reduce his money income by compensating variation in income. While leisure yields satisfaction to the individual directly, income represents general purchasing power capable of being used to buy goods and services for satisfaction of various wants. According to Watson, An indifference schedule is a list of combinations of two commodities the list being so arranged that a consumer is indifferent to the combinations, preferring none of any other. The following is an imaginary indifference schedule representing the various combinations of goods X and Y. As in case of change in price, rise in wage rate has both the substitution effect and income effect. An indifference curve denotes a set of different combinations of two commodities or goods, providing the same level of satisfaction to the consumer. But there are some budget constraints due to the low income of the consumer. Perfect complementary goods are used in a certain fixed ratio. This trade-off means how much income the individual is willing to accept for one hour sacrifice of leisure time. Privacy Policy3. In Fig. Thus above the horizontal line B1C1 the combinations of other goods and food are not attainable when he is given the food stamps of Rs. 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 cookie is used to store the user consent for the cookies in the category "Other. On the other hand in case of cash subsidy the government provides a lump sum cash income to the consumer. As explained above in Fig. 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. But when he is already supplying a large amount of labour and earning sufficient income, further increases in wage rate may induce the individual to demand more leisure so that income effect may outweigh the substitution effect at higher wage rates. 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. Consumer goods companies and the industry offer a vast range of products that heavily contribute to the global economy.read more, the curve features unique combinations or consumption bundles for any two commodities in points. This cookie is set by GDPR Cookie Consent plugin. This website uses cookies to improve your experience while you navigate through the website. Besides, a lower price of food due to price subsidy on it induces the consumer to substitute food for other goods causing greater consumption of food as compared to the scheme of lump-sum cash grant which have no such substitution effect and permits free choice of goods to the individual according to his own preference. All Combinations on an Indifference Curve Give Same Level of Satisfaction As we defined the indifference curvegiving the same level of satisfaction with the different points of combinations of two commodities A, B, C, D and E combinations. 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. This happens because the preferences of the individual between food and other commodities are such that he wants to have more than B1C quantity of food which is the quantity of food provided under the food stamp subsidy. 10 per kg., then with Rs. In other words, an indifference curve shows the different bundles of goods that a person is indifferent between, as they all provide the same level of utility or satisfaction to the individual. An indifference curve is a curve that represents all the combinations of goods that give the same satisfaction to the consumer. Thus, movement from point S to H and as a result the decrease in labour supply by L2 L1 represents the income effect of the rise in wage rate. In this optimal situation, income- leisure trade off (i.e. Combination L contains more of both goods X and Y than combination M on IC1. However, the more important and relevant case of rationing is depicted in Figure 11.8. The theory of consumption is based on the scale of preference and the ordinal ranks or orders of one's preferences. . Now, consider Figure 11.10 where it will be seen that ration limit Ry is smaller than consumers optimum consumption of Y as indicated by combination E of the two goods on the budget line BL which has been drawn with his given income and prices of two goods. You can calculate it by, Consider Fig. He is supposed to rank them in his order of preference and can state if he prefers one combination to the other or is indifferent between them. Budget Line: Notes on Budget Line, Space, Changes and Slope. Examples of goods that are perfect substitutes are not difficult to find in the real world. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Jack is satisfied with 1 unit of cloth and 8 units of books. It allows the consumer to buy within a given budget, i.e., within their current income. It is the income that serves as a binding on his consumption choice and not the ration limit. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Property III: Indifference curves cannot intersect each other: Third important property of indifference curves is that they cannot intersect each other In other words only one indifference curve will pass through a point in the indifference map 1 his property can be easily proved by first making the two indifference curves cut each other and then showing the absurdity or self-contradictory result it leads to. The following diagram showing an indifference map consisting of three curves: We know that a consumer is indifferent among the combinations lying on the same indifference curve. In this case with cash subsidy the individual spends more than his initial income OB1 on other goods. A higher indifference curves to the right of another represents a higher level of satisfaction and preferable combination of the two goods. Disclaimer Copyright, Share Your Knowledge Necessary cookies are absolutely essential for the website to function properly. It shows the consumers preference for one good over another only if it is equally satisfying. That is, at wage rate w0he supplies TL0 amount of labour. Consider Figure 11.15 where leisure is measured in the rightward direction along the horizontal axis and the maximum leisure time is OT (equal to 24 hours). The preference-maximising point A on indifference curve I 1 shows that . It will be seen from Figure 11.2 that with food subsidy RM, the individual is having OA amount of food, whereas with equivalent cash payment of PC the individual purchases OB amount of food which is less than OA. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. The curves that are farther away from the origin represent higher levels of satisfaction as they have larger combinations of X and Y. 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). Content Guidelines 2. The food stamp programme can affect the recipient in two ways. This is an important feature of an indifference curve. The latter shows the various combinations of the two commodities such that the consumer is indifferent to those combinations. An indifference curve is a downward sloping convex line connecting the quantity of one good consumed with the amount of another good consumed. That is, income effect of the rise in wage rate on leisure is positive, that is, leads to the increase in the hours of leisure enjoyed (that is, tends to decrease labour supply). If you enjoy both pizza and pasta, for example, you might not care whether you purchase 20 pizzas and no pasta . Now consider Figure 11.7 where ration limit is fixed at Rx which lies to the left of L. This ration limit reduces or truncates his market opportunity set (i.e. This cookie is set by GDPR Cookie Consent plugin. Higher indifference curve represents larger bundles of goods i.e. This cookie is set by GDPR Cookie Consent plugin. Analytical cookies are used to understand how visitors interact with the website. 11.19 that income effect is stronger than substitution effect so that the net result is reduction in labour supply by L0L1 work-hours. With given income of the consumer and prices of the two goods we draw a budget line BL in Figure 11.6. Required fields are marked *. The slope of the indifference curve measuring marginal rate of substitution between leisure and income (MRSLm ) shows the tradeoff between income and leisure. (With Diagram) Hence, consumers will demand more goods when prices are less. labour supply) L0L2 for leisure. Now, when the wage rate rises to w1, wage line or income-leisure line shifts to TM1 (w1 = OM1/OT), the individual reduces his leisure to OL1 and supplies TL1 hours of work; L1L0 more than before (see Panel (a) in Figure 11.18). 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. So, it will be seen from Figure 11.5 that with the imposition of lump sum tax equivalent in terms of revenue raising to the excise duty, we have drawn the budget line AB which is passing through the point Q1. 8.8. A normal indifference curve will be convex to the origin and it cannot be concave. We also use third-party cookies that help us analyze and understand how you use this website. In other words, PN is the market price of OA quantity of food. Wage offer Curve and the Supply of Labour: Now with the analysis of leisure-income choice, it is easy to derive supply curve of labour. 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. 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. On the other hand, an indirect tax is one which can be passed on or shifted to others by raising the prices of the goods. It has freed the theory of consumption from the unrealistic assumptions of the Marshallian utility analysis. 11.4 . In the case of any consumer, the utility refers to gain from the consumption of two commodities. 200 provided to him, while spending his entire income OB on other goods. Thus, while income effect of the increase in wage rate causes decrease in labour supply by L2L1, its substitution effect causes increase in labour supply by L0L2. It does not store any personal data. Let us consider commodities B1 and B2. An indifference curve reveals many combinations of two goods a consumer prefers to consume. We know that consumers in actual world do not generally buy and consume one good. Also referred to as final products, examples of consumer goods include an Apple cellphone or a box of Oreo cookies. However, the actual choice of income and leisure by an individual would also depend upon what is the market rate of exchange between the two, that is, the wage-rate per hour of work. Food Stamp Programme: In-kind Food Subsidy: Food stamp programme is a type of food subsidy to provide poor people with adequate quantity of food. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. An indifference curve (IC) is a graphical representation of different combinations or consumption bundles of two goods or commodities, providing equal levels of satisfaction and utility for the consumer. In other words, to increase leisure by one hour, an individual has to forego the opportunity of earning income (equal to wage per hour) which he can earn by doing work for an hour. For example, Dalda and Rath Vanaspati, two different brands of cold drink such as Pepsi Cola and Coca Cola are generally considered to be perfect substitutes of each other. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Copyright 2023 .

In other words, besides analysing consumers demand, indifference curves have several other applications. Meaning of Indifference Curve 2. Only convex curves will lend to the principles of Diminishing Marginal Rate of substitution. Since at the given market price of food, he can buy ,C amount of food with the food stamps of Rs. You are free to use this image on your website, templates, etc., Please provide us with an attribution link. In fact, it would always be so whatever the subsidy and whatever the preferences of consumers so long as only the indifference curves remain convex and smooth.

It will be seen from Figure 11.9 that ration amounts of Rx and Ry of goods X and Y respectively are greater than OM and ON which the consumer is buying with his price-income situation. It is worth noting that the movement from Q3 on indifference curve IC3 to Q1 on indifference curve IC1 is the combined result of the income effect and substitution effect caused by the excise duty. But opting out of some of these cookies may affect your browsing experience. Further, these stamps cannot be traded or transferred to the other people. Copyright 10. For instance, a child might be indifferent while having a toy, two comic book, four toy trucks and a single comic book. The degree of convexity of an indifference curve depends upon the rate of fall in the marginal rate of substitution of X for Y. The straight line MT is the budget constraint, which in the present context is generally referred to as income-leisure constraint and shows the various combinations of income and leisure among which the individual will have to make a choice. set of attainable combinations of two goods X and Y) as shown by the reduced shaded area in Figure 11.7 and therefore in this case the ration limit is only potentially binding on him. It will be seen that with ration limit fixed at ORx rationing does not act as a binding at all and prove to be quite ineffective in restricting the consumption of good X which is the objective of the policy. The cookie is used to store the user consent for the cookies in the category "Other. Without this type of analysis, economists would be unable to predict certain behaviors . Straight-line indifference curves of perfect substitutes are shown m Fig. Thus, he has sacrificed L1 L2 more leisure to do overtime work and earns M1M2 more income than before. 11.3 the individual maximises his satisfaction at point E2 where his budget line is tangent to indifference curve IC2. Content Guidelines 2. All other variables remain constant. In the curve, the quantity consumed by B2 will compensate for the increase in the amount consumed by B2. He is in equilibrium at point E where he consumes quantity of good X which is smaller than the ration amount Rx. In this case, therefore, B1C, will be equal to 20 kg. It will be seen from Fig. Now let us assume that he is given the cash subsidy of B1 B2 so that with the given market price of food, budget line shifts to B2L2. This must be so if the, level of satisfaction is to remain the same on an, Jomo Kenyatta University of Agriculture and Technology, L.N.Gumilyov Eurasian National University, Kwame Nkrumah University of Science and Technology, Law, Governance, Economy and Society (FOUN 1301), Bachelor of Science in Information Technology (C025), Bachelor of Business Administration (BBA), FOUNDAMENTALS OF NURSING SCIENCE (NRSG 212), Cost and Management Accounting I (AcFn-M2091), Avar Kamps,Makine Mhendislii (46000), Power distribution and utilization (EE-312), PFE Les moyens de preuve dans les contrats lectroniques en Droit Marocain, MCQS Probablity ,Events,laws of probability, Public Goods Vs Private Goods - Difference and Comparison - The Investors Book, Pdfcoffee - the test bank of chapter nine in financial management its important and effective, Leadership and Management MCQS with answer, Applied M I Lnote - Lecture notes All chapters, Written test possible answers for the post of Administrative Officer Grade 12, Business Statistics and Mathematics Solved Past Papers, B.com Part 1 Punjab University 2009-2018, 462802814 Government accounting final examination with answer and solution docx, Assignment 1.
