importance of indifference curve with diagram

The marginal rate of substitution (MRS) indicates if a consumer is willing to sacrifice one good for another commodity while maintaining the same level of utility. Thus, in Figure 11.5, imposition of an equivalent lump-sum or income tax, the consumer moves from the equilibrium position Q3 on indifference curve IC3 to the new position Q2 on indifference curve IC2 which represents the income effect. 11.20. Prohibited Content 3. Hence, the curve obtained is always convex. If the purpose is to increase the consumption of food and therefore provide adequate diet to the people, then food stamp subsidy is better than cash subsidy as under the former, the individual is constrained to buy at least a given quantity of food. The indifference curve slopes down from left to right on the graph. Therefore, given that the consumer is free to spend money as he likes, with cash grant his new equilibrium position must be to the left of point R on the budget line CD where it will be tangent to the higher indifference curve than IC2. TL1 is the hours worked at the wage rate w represented by the slope of the income-leisure line MT. The loss of satisfaction to the consumer on account of the downward movement must be made up by the gain through the rightward movement. These combinations provide the same level of satisfaction and utility to the consumer. 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. This cookie is set by GDPR Cookie Consent plugin. This means that if individual is paid PE amount of money (say as a cash grant), he reaches the same indifference curve IC (same level of welfare) at which he is when price subsidy is paid by the Government on food. Therefore, we can draw indifference curves between income and leisure both of which give satisfaction to the individual. This cookie is set by GDPR Cookie Consent plugin. In its analysis, core principles of microeconomics are involved. With a given money income OB1 of an individual and given market price of food, B1L1 is the budget line whose slope represents the price of food (Note that price of money represented on the X-axis is Re. We shall study below that indirect tax such as excise duty income causes excess burden on the individuals, that is, indirect tax reduces welfare more than the direct tax, say income tax when an equal amount of revenue is raised through them. 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. Economists have adopted the principles of. But the two indifference curves cutting each other lead us to an absurd conclusion of A being equal to Bin terms of satisfaction. TOS 7. 200 he can buy 20 kg of food. In order to earn income for satisfying his wants for goods and services, he will devote some of his time to do work. Assumptions of Indifference Curve. He can utilize the following combinations based on his choice: The indifference curve analysis is indicated with a graphical representation. 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. TOS4. It indicates that the slope of the curve is negative. The theory applies to welfare economics and microeconomicsMicroeconomicsMicroeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply.read more, such as consumer and producer equilibrium, measurement of consumer surplusConsumer SurplusConsumer 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). It, thus, maintains the same level of consumer satisfaction in all combinations. The cookie is used to store the user consent for the cookies in the category "Performance". Therefore, the ration limits in this case are not actually binding since these do not any more constrain his consumption. Further, he is better off than before as he is now at the higher indifference curve IC2. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. Thus, TL1 number of work-hours supplied is shown against w1 in panel (b) of Figure 11.18. Content Guidelines 2. An indifference curve is the locus of all those combinations of two goods that yields the same level of utility (satisfaction) to the consumer so that the consumer is indifferent to purchase the particular combination s/he selects. We have taken only one schedule, but any number of schedules can be taken for the two commodities. Privacy Policy3. In this equilibrium position the individual works for TL1 hours per day (TL1 = OT-OL1). An indifferent curve is drawn from the indifference schedule of the consumer. read more, theory of exchange, etc. 1., that is, price of rupee one is Re. It helps us visualize the different combinations of goods and services, each of which yields the same level of utility. Share Your Word File When a curve intersects the budget limit of an individual consumer, it creates an optimal consumption bundle. The cookie is used to store the user consent for the cookies in the category "Other. Some of the important problems are explained below with the help of this technique. It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. It is like a contour map showing the height of the land above sea-level where instead of height, each indifference curve represents a level of satisfaction. The net combined effect on the supply of labour (hours worked) depends on the magnitude of the substitution effect and income effect of the rise in wage rate. This is depicted in Figure 11.17 where at the equilibrium point E a steeper leisure-income line EK than MT has been drawn. 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. 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. 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 marginal rate of substitution shows the consumers preference for one good over another while maintaining the same level of utility.

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. 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. Our mission is to provide an online platform to help students to discuss anything and everything about Economics. Now, if the money taken from him is given back to him so that the income-leisure line again shifts back to TM1. 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. It could be calculated by dividing the additional utility by the amount of additional units.read more theory, the subjective theory of value, substitution effects, income, ordinal utility, etc. At the old price (before the excise duty was imposed), he could purchase ON quantity of good X for PT amount of money. The budget line is tangent to indifference curve IC2 at point 'E'.

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. IC2 is the higher indifference curve than IC1. 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. Combination Q has been taken on a higher indifference curve IC2 and combination S on a lower indifference curve IC1. Image Guidelines 5. Thus, with the rise in wage rate, supply of labour has decreased by L0L1. The slope of the indifference curve measuring marginal rate of substitution between leisure and income (MRSLm ) shows the tradeoff between income and leisure. Thus, with the rise in wage rate above W1,labour supply decreases. 11.3. Theindifference curve in economicsexamines demand patterns for commodity combinations, budget constraints and helps understand customer preferences. 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. The consumer is rational to maximize the satisfaction and makes a transitive or consistent choice. In this case with cash subsidy the individual spends more than his initial income OB1 on other goods. Thus, the consumer will definitely prefer A to B, that is, A will give more satisfaction to the consumer than B. You also have the option to opt-out of these cookies. 11.4 . Lump sum tax, proportionate and progressive income taxes, wealth tax, death duty are the examples of direct tax. 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. By clicking Accept, you consent to the use of ALL the cookies. Since we are assuming that subsidy paid by the Government is half the market price of food, the consumer would pay half the market price. Where the X-axis indicates one commodity (Cloth) and Y-axis refers to another good (Book). Irish-born British economist Francis Ysidro Edgeworth first proposed this two-dimensional graph, also known as the iso-utility curve. Introduction to Indifference Curve and Perfect Substitutes. Consider Fig. 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. bundles which contain more of both or more of at least one. 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. To break up this wage effect on labour supply, we reduce his money income by compensating variation in income. MRSxy is always diminishing. Lastly, out of the two possibilities of the effects of food-stamp subsidy and cash subsidy which is the most common result, that is, the most common outcome of the two possible cases presented in Fig. An indifference curve has a negative slope, i.e. With the imposition of a lump-sum tax (or any other income tax), a certain income is taken away from the consumer and he is pushed to the lower indifference curve (or a lower level of welfare) but he is free to spend the income he is left with as he likes without forcing him to substitute one commodity for another due to any change in relative price.
