Suppose that under food-subsidy programme, the needed families are entitled to purchase food at half the market price, the other half of the market price is paid by the Government as subsidy.

Lump-sum tax has reduced the individuals welfare less than that by the excise duty. It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. We therefore conclude that indifference curves cannot cut each other. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. In this figure we measure money income on the Y-axis and leisure (reading from left to right) and labour supply (reading from right to left) on the X-axis. 4 Important Properties of Indifference Curve (with curve diagram) - - StuDocu. Thus, the consumer will definitely prefer A to B, that is, A will give more satisfaction to the consumer than B. Share Your PPT File. Suppose now that Government levies an excise duty (an indirect tax) on good X. What is the shape of IC, when MRS between good X and Y is diminishing? Therefore, RM is also greater than PE. This supply of labour is directly shown against wage rate w0 in panel (b) of Figure 11.18. Such a diagram is known as an indifference map where each indifference curve corresponds to a different indifference schedule of the consumer. The same argument holds good in this case as developed above in the case of intersection of indifference curves. We know that consumers in actual world do not generally buy and consume one good. With the imposition of lump sum tax, the price line will shift below but will be parallel to the original price line PL1. 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. 11.8 he is at lower indifference curve IC0 indicating his lower level of welfare. Share Your PDF File It is important to note that leisure is a normal commodity which means that increase in income leads to the increase in leisure enjoyed (i.e. 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. Therefore, we can draw indifference curves between income and leisure both of which give satisfaction to the individual. We also use third-party cookies that help us analyze and understand how you use this website. 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. It will be seen from Figure 11.1 that budget line EF touches the indifference curve IC at a point S and is buying OB quantity of food. This trade-off means how much income the individual is willing to accept for one hour sacrifice of leisure time. Share Your PPT File. In our Figure PE = MK (the vertical distance between two parallel lines) and RM is greater than MK. Authorized users may be able to access the full text articles at this site. One possibility is that with the food-stamp subsidy and resultant kinked budget line B1CL2, in Fig. It allows the consumer to buy within a given budget, i.e., within their current income. Let us take the case of food subsidy which is given by the Government to help the needy families. 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.

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. If a consumer purchases two goods, the budget limitation can be displayed with the help of a budget line on a graph. Whereas income effect of the rise in wage rate tends to reduce supply of labour, substitution effect tends to increase it. . But ration limit Rx for good X is larger than his optimum or equilibrium consumption quantity of good X. But opting out of some of these cookies may affect your browsing experience.

With the budget line B1CL2 with food stamp subsidy of B1C, the best that the individual can do is to choose the corner point C of budget line B1CL2 which lies on the highest possible indifference curve IC2 which passes through the point C. Therefore, from the point of individual welfare we reach our earlier conclusion that cash subsidy is superior to in-kind subsidy represented by food stamps programme. Assumes marginal rate of substitution to diminish. When it occurs, it is known as the marginal rate of substitution (MRS). Plagiarism Prevention 4.

The effect of this subsidy on consumers welfare and money value of this subsidy to the consumer is illustrated in Figure 11.1 where the quantity of food is measured on the X- axis and money on the Y-axis. Answer (1 of 7): Indifference curve analysis is very important to the study of economics. Here is an example to understand the indifference curve better. This means that up to a point substitution effect is stronger than income effect so that labour supply curve slopes upward, but beyond that at higher wage rates supply curve of labour bends backward. 8.6.

Our analysis is based on two assumptions. It makes the consumer indifferent to any of the combinations of goods shown as points on the curve. That is, these food stamps cannot be used to buy non-food goods. (With Diagram) Hence, consumers will demand more goods when prices are less. 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. 11.3 the individual maximises his satisfaction at point E2 where his budget line is tangent to indifference curve IC2. These cookies ensure basic functionalities and security features of the website, anonymously. Share Your Word File (5) The consumers tastes, habits and income remain the same throughout the analysis. To do so we take away so much income from the individual that he comes back to the original indifference curve IC1.

In order to earn income for satisfying his wants for goods and services, he will devote some of his time to do work. In this case with cash subsidy the individual spends more than his initial income OB1 on other goods. will work for less hours). In this article we will discuss about Indifference Curves. Budget Line: Notes on Budget Line, Space, Changes and Slope. Now, suppose the individual is given food stamps of Rs. 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. The latter shows the various combinations of the two commodities such that the consumer is indifferent to those combinations. We will also demonstrate how the effect of food-stamp subsidy differs from cash subsidy. If instead of giving RM as price subsidy on food, Government pays the individual cash money equal to PE, the individual will reach the same level of welfare as he does with RM subsidy. This means for most of the recipients, food stamp programme has the same effect as a cash subsidy. 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. Also referred to as final products, examples of consumer goods include an Apple cellphone or a box of Oreo cookies. 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. In Fig. It is for this reason that we reject indifference curves of concave or straight-line shapes and assume that indifference curves are normally convex to the origin. In panel (b), the information supplied by the wage-offer curve, that is, the supply of labour (work-hours) by the individual at different wage rates is shown directly as, in this panel, supply of labour (hours worked) is measured along the X-axis and wage rate along the Y-axis. that is, non-food items) too. Introduction to Indifference Curve and Perfect Substitutes. 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. Perfect complementary goods are used in a certain fixed ratio. It Dispenses with Cardinal Measurement of Utility 2. This property of indifference curves follows from assumption 3, which is that the marginal rate of substitution of X for Y (MRSxy) diminishes as more and more of X is substituted for Y. Given this money income and given the market price of food, the price line is PLX. By purchasing OA quantity of food, the individual is spending PT amount of money. In particular we are interested in knowing whether it is the ration limits or income of the consumer that is binding, that is, which forces the consumer to consume less amounts of the goods. This leads us to income-leisure constraint which together with the indifference map between income and leisure would determine the actual choice by the individual. Where the X-axis indicates one commodity (Cloth) and Y-axis refers to another good (Book). Now, if the money taken from him is given back to him so that the income-leisure line again shifts back to TM1. Thus, the cash money equivalent of the price subsidy to the individual is less than the cost of the subsidy to the Government. Some of these important properties of indifference curve are as follows: 1. In other words, the indifference curve is relatively flatter in its right-hand portion and relatively steeper in its left-hand portion. The indifference curve slopes down from left to right on the graph. It does not store any personal data. Meaning of Indifference Curve: The indifference curve analysis measures utility ordinally. In Figure 6, consider the indifference curves I 1 and I 2 and combination N and A respectively on them. In Figure 11.11 both ration limits Rx and Ry are actually binding and force the individual to consume less of both the commodities than he consumes at his equilibrium position E in the absence of rationing of the two commodities. 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. Thus, in this possibility, the effect of equivalent cash subsidy is exactly the same as the effect of food stamp subsidy. We shall explain below only few applications. 11.3 and Fig. Share Your Word File This property follows from assumption I. Indifference curve being downward sloping means that when the amount of one good in the combination is increased, the amount of the other good is reduced. it slopes downward from left to right. bundles which contain more of both or more of at least one. But a glance at Fig.8.5 will show that this is absurd conclusion since combination A contains more of good Y than combination B, while the amount of good X is the same in both the combinations. Disclaimer Copyright, Share Your Knowledge This has been a guide to What is Indifference Curve and its Definition. "Nothing is more important than my child's safety" is a corner solution in its refusal to admit there might be trade . To do overtime work, he will have to sacrifice more leisure-time and therefore to provide him incentive to forego more leisure and thus to work for more hours it is required to pay him higher wage rate. Thus, he has sacrificed L1 L2 more leisure to do overtime work and earns M1M2 more income than before. Here, we understand that all three products resting in the indifferent curve give him the same satisfaction. 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. But there are a number of indifference curves, as shown in Figure 2. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. 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. It's essentially the cost of the next best alternative that has been forgiven. This website uses cookies to improve your experience while you navigate through the website. Thus PE, is money value of the subsidy to the individual. Hence, the curve obtained is always convex. The indifference curve indicates the various combinations of two goods that yield equal satisfaction to the consumer. Consumer goods are the products purchased by the buyers for consumption and not for resale. In India also food stamp programme has been suggested in recent years as an anti-poverty measure. An important application of indifference curves is to judge the welfare effects of direct and indirect taxes on the individuals. On the other hand, the rise in wage rate increases the opportunity cost or price of leisure, that is, it makes enjoyment of leisure relatively more expensive. On the other hand in case of cash subsidy the government provides a lump sum cash income to the consumer. TL1 is the hours worked at the wage rate w represented by the slope of the income-leisure line MT. This cookie is set by GDPR Cookie Consent plugin. Consumer goods companies and the industry offer a vast range of products that heavily contribute to the global economy. He decides to exchange 4 units of books for an additional piece of cloth. The indifference curve analysis retains some of the assumptions of the cardinal theory, rejects others and formulates its own. You can calculate it by, 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. If the individual can work for all the 24 hours in a day, he would earn income equal to OM. 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. The usefulness of the indifference curves: it helps to distinguish between the substitution effects and the incomes effects. In other words, at point Q2 individuals level of welfare is higher than at Q1. 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. It provides equivalent satisfaction and utility levels for the consumer. The consumer is rational to maximize the satisfaction and makes a transitive or consistent choice. Of course, these ration limits narrow down or truncate his market opportunity set at both ends on the X and Y axes, and in this way they are potentially binding but they are not effective in restraining his consumption. 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. goods other than food). It can slope or bend backward too which implies that at a higher wage rate, the individual will supply less labour (i.e. Report a Violation, The Supply Curve of Labour (Explained With Diagram), The Uses or Application of Indifference Curve Analysis | Economics, Relationship between Price Consumption Curve and Price Elasticity of Demand.

The budget line is tangent to indifference curve IC2 at point 'E'. 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. It could be calculated by dividing the additional utility by the amount of additional units. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Some of the important problems are explained below with the help of this technique. However, it is important to note that he . 200 provided to him, while spending his entire income OB on other goods. 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. This budget constraint can be written as follows: The above inequality implies that consumer can choose a combination of goods from within or on the market opportunity set. Usually, the combination with the higher satisfaction level is preferred. At the old price (before the excise duty was imposed), he could purchase ON quantity of good X for PT amount of money. It comprises individual choices, marginal utilityMarginal UtilityA customer's marginal utility is the satisfaction or benefit derived from one additional unit of product consumed. With equivalent food stamp subsidy of B1C the individual has to choose a point which must be on the kinked budget line B1CL2. The basic reason for this is that whereas both the lump-sum tax (or any other general income tax) and an indirect tax reduce consumers income and produce income effect, the indirect tax in addition to the income effect, also raises the relative price of the good on which it is levied and therefore causes substitution effect. This shows that a part of food stamp subsidy is indirectly used to finance the increased consumption of other goods. The derivation of supply curve of labour is depicted in 11.18. Before the receipt of food stamps the individual is in equilibrium at point E1 on indifference curve IC1 and is consuming OF1 quantity of food and ON1 quantity of other goods per week. 10 per kg. This is depicted in Figure 11.17 where at the equilibrium point E a steeper leisure-income line EK than MT has been drawn. The superiority of cash grant in terms of its impact on the welfare of the individuals can be explained in a slightly different way. Now, if substitution effect had been larger than income effect, work-hours supplied would have increased as a result of rise in wage rate. We will further show how much K work effort (i.e. The cookie is used to store the user consent for the cookies in the category "Performance". That the individual with cash transfer must be better off and his food consumption must be less as compared with price subsidy on food is due to the fact that indifference curves being convex, the budget line CD obtained with cash transfer must intersect the indifference curve IC1 at point R reached with the equivalent price subsidy. Hence IC2 curve gives more satisfaction. The theory of consumption is based on the scale of preference and the ordinal ranks or orders of one's preferences. Thus income provides satisfaction indirectly. If a tangency point is reached between the indifference curve and budget line then you do not have a corner .
