However, with AB as the price line, individual is in equilibrium at point Q2 on indifference curve IC2 which lies at a higher level than IC1. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. 11.3 the individual maximises his satisfaction at point E2 where his budget line is tangent to indifference curve IC2. On the other hand, an indirect tax not only reduces the purchasing power or real income of the consumer causing income effect, but also produces price-induced substitution effect and thus forcing him to purchase less of the commodity on which indirect tax has been levied and buy more of the non-taxed commodity. Thus, with the rise in wage rate, supply of labour has decreased by L0L1. He is also satisfied with 2 units of cloth and 4 units of books. As explained above in Fig. Since all the combinations give the same amount of satisfaction, the consumer prefers them equally. If the income effect is stronger than the substitution effect, the net combined effect of rise in wage rate will be to reduce labour supply. It can slope or bend backward too which implies that at a higher wage rate, the individual will supply less labour (i.e. He has earned OM1 amount of income by working TL1 hours of work. In other words, PN is the market price of OA quantity of food. IC2 is the higher indifference curve than IC1. Thus, the maximum amount of leisure time that an individual can enjoy per day equals 24 hours. 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. all of which provide satisfaction to the individual. Copyright 10. The ordinal utility theory or the indifference curve analysis is based on the assumptions as discussed above. (6) He prefers more of X to less of Y or more of Y to less of X. This is the point of consumer equilibrium, where the consumer purchases OM quantity of commodity 'X' and ON quantity of commodity 'Y. 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. Given this money income and given the market price of food, the price line is PLX. This is directly plotted against the wage rate w0 in panel (b) of Fig. 8.7. Suppose further that price of food is Rs. Therefore, we can draw indifference curves between income and leisure both of which give satisfaction to the individual. The cookies is used to store the user consent for the cookies in the category "Necessary". A single indifference curve concerns only one level of satisfaction. 11.2 which passes through point R. It will be seen from Figure 11.2 that with the budget line CD though the individual can buy the same market basket R, if he so desires, which he was purchasing with price subsidy on food, he is actually in equilibrium at point H on higher indifference curve IC2. It follows that PE is less than RM. However, such a situation is relevant in case of a poor family whose income is so small that it cannot buy even the rationed quantity. 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. It, thus, maintains the same level of consumer satisfaction in all combinations. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. The assumptions of the ordinal theory are the following: (1) The consumer acts rationally so as to maximise satisfaction. 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. 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. 200 provided to him, while spending his entire income OB on other goods. This cookie is set by GDPR Cookie Consent plugin. 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. Therefore, in economics leisure is regarded as a normal commodity the enjoyment of which yields satisfaction to the individual. This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. 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. Figure 11.11 depicts the case of a relatively rich person who without the binding of rationing is at point E on indifference curves IC1 and is consuming greater quantities of the two goods than the ration amounts. With given income of the consumer and prices of the two goods we draw a budget line BL in Figure 11.6. The very important feature of the indifference curves is that they are convex to the origin and they cannot be concave to the origin. 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.

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. This increases the consumption of non-food items also. 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. 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 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). 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. 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. He can utilize the following combinations based on his choice: The indifference curve analysis is indicated with a graphical representation. It is a form of in-kind food subsidy in contrast to the subsidy provided in the form of cash income, often called cash subsidy. At the old price (before the excise duty was imposed), he could purchase ON quantity of good X for PT amount of money. However, it is important to note that he . 200 he can therefore buy 20 kg of food which is equal to B1C at the given market price. The budget line is tangent to indifference curve IC2 at point 'E'. Consider Figure 11.5 where on the X-axis, good X and on the F-axis money is measured. This cookie is set by GDPR Cookie Consent plugin. By purchasing OA quantity of food, the individual is spending PT amount of money. 4 Important Properties of Indifference Curve (with curve diagram), Copyright 2023 StudeerSnel B.V., Keizersgracht 424, 1016 GC Amsterdam, KVK: 56829787, BTW: NL852321363B01, This property implies that an indifference curve, 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. In other words, a consumer is considered indifferent between any two bundles indicated by a point on the curve, provided these combinations give the same utility. Our analysis is based on two assumptions. In order to find the money value of the subsidy to the individual, draw a line EF parallel to PL1 so that it touches the same indifference curve IC where the individual comes to be in equilibrium when subsidy is paid. It is the income that serves as a binding on his consumption choice and not the ration limit. This must be so if the level of satisfaction is to remain the same on an indifference curve. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. 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. Another important conclusion from this possible case is that with either food stamp subsidy or cash subsidy the individual buys more of both food and other goods than he buys before the grant of subsidy.

Thus PE, is money value of the subsidy to the individual. Also referred to as final products, examples of consumer goods include an Apple cellphone or a box of Oreo cookies. Indifference curves are heuristic devices used in contemporary microeconomics to demonstrate consumer preference and the limitations of a budget. Content Filtrations 6. It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. Now, the important question is what is the money value of this price subsidy (RM) on food to the individual. These combinations provide the same level of satisfaction and utility to the consumer. 1. Now suppose that wage rate rises to w1 with the result that income-leisure constraint line rotates to TM1. Content Guidelines 2. Second, wage rate is the same irrespective of the number of hours he chooses to work. In this optimal situation, income- leisure trade off (i.e. 11.20. 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. In geometric terms, it will be seen from Figure 11.14 that on indifference curve IC1 at point A the individual is willing to accept M income for sacrificing an hour (L) of leisure. This is a substitution effect of the rise in wage rate tends to reduce leisure and increase labour supply (i.e. At this new equilibrium point E2 he is purchasing Of2 quantity of food and ON2 of other goods. Hence IC2 curve gives more satisfaction. He now works for TL2 hours per day, TL1 at hourly wage rate w and L1L2 at higher wage rate w. The cookie is used to store the user consent for the cookies in the category "Analytics". It's essentially the cost of the next best alternative that has been forgiven. It allows the consumer to buy within a given budget, i.e., within their current income. Jack has 1 unit of cloth and 8 units of the book. 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, the cash money equivalent of the price subsidy to the individual is less than the cost of the subsidy to the Government. It could be calculated by dividing the additional utility by the amount of additional units. It Dispenses with Cardinal Measurement of Utility 2. Thus, indifference curves have been used to explain the concept of consumers surplus, substitutability and complementarity of goods, supply curve of labour of an individual, several principles of welfare economics, burden of different forms of taxation, gain from foreign trade, welfare implications of subsidy granted by the Government, index number problem, mutual advantage of exchange of goods between two individuals and several other things. Thus, if instead of the food stamps the individual is given equivalent cash income of B1B2 (Note that with given market price of food, cash income of B1B2 can buy B1C quantity of food and thus the two are equivalent), the budget line will shift from L2 to B2 L2. It makes the consumer indifferent to any of the combinations of goods shown as points on the curve. 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. You also have the option to opt-out of these cookies. A normal indifference curve will be convex to the origin and it cannot be concave. Further, if the same amount of revenue is to be raised through lump-sum tax as with the excise duty, then the new price line AB should be drawn at such a distance from the original price line PL1 that it passes through the point Q1. The indifference curve indicates the various combinations of two goods that yield equal satisfaction to the consumer. Content Guidelines 2. We cannot predict the specific result purely on theoretical grounds. 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. The slope of the budget line represents the relative pricing of two commodities. Indifference curve must be convex to the origin: 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). In this equilibrium position the individual works for TL1 hours per day (TL1 = OT-OL1). Consumer Surplus = Maximum Price to be paid willingly Actual Paid Price 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. Hence, a consumer prefers to reach the tallest line to attain a higher utility level. For instance, a child might be indifferent while having a toy, two comic book, four toy trucks and a single comic book. This website uses cookies to improve your experience while you navigate through the website. 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. Lump-sum tax has reduced the individuals welfare less than that by the excise duty. Property I. Indifference curves slope downward to the right: This property implies that an indifference curve has a negative slope. Indifference curves between income and leisure are therefore also called trade-off curves. Thus income provides satisfaction indirectly. 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. Likewise, the combinations B and C will give equal satisfaction to the consumer; both being on the same indifference curve IC1. 10 per kg., then with Rs. goods other than food). The indifference curve analysis measures utility ordinally. it helps to compare the satisfaction of different goods/commodities and enables the consumer to attain the equilibrium. 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. 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. 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. You consent to our cookies if you continue to use our website. 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. Until the early 20th century, economists had been unable to provide a . Thus, to quote Prof. Watson again, you can make someone happier if you give him cash instead of a commodity, even if the commodity is something he wants. We will further show how much K work effort (i.e. We shall explain below only few applications. Analytical cookies are used to understand how visitors interact with the website. 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. 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. Content Guidelines 2. We therefore conclude that indifference curves cannot cut each other. Privacy Policy 8. cannot always be validly applied to the Government subsidy programme since the above principle is based upon the subjective benefits to the individuals which is not always the correct criteria to judge the desirability of Government subsidy programme. Straight-line indifference curves of perfect substitutes are shown m Fig. Effect of Rationing On Consumers Welfare: Indifference curve analysis can be used to explain under what conditions rationing of goods by the Government can act as binding or a constraint on consumers choices and further how it affects his welfare. Further, these stamps cannot be traded or transferred to the other people. But given the preferences of the individual between food and other goods, he is in equilibrium at the same point E2 at which his budget line B2L2 is target to the indifference curve IC2. This supply of labour is directly shown against wage rate w0 in panel (b) of Figure 11.18. Thus the trade-off between income and leisure at this point is M/L. And this later substitution effect caused due to the price-distortion by the indirect tax further reduces his welfare. The greater the amount of this sacrifice of leisure, that is, the greater the amount of work done, the greater income an individual earns. An indifference curve reveals many combinations of two goods a consumer prefers to consume. The derivation of supply curve of labour is depicted in 11.18. The consumer behavior remains constant in the analysis. An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Indifference curve analysis can be used to explain an individuals choice between income and leisure and to show why a higher overtime wage rate must be paid if more hours of work are to be obtained from the workers. Here is an example to understand the indifference curve better. In this article we will discuss about Indifference Curves. Therefore, as a result of rise in wage rate individual substitutes work (and therefore income) for leisure which leads to the increase in supply of labour. With the further increase in wage rate to w2, the income-leisure constraint rotates to TM2 and the individual is in equilibrium when he supplies L2 work-hours which are smaller than L1. 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. Each indifference curve represents various alternative combinations of income and leisure which provides equal level of satisfaction to the individual and the farther away an indifference curve is from the origin, the higher the level of satisfaction it represents for the individual. 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. How the effect of rise in wage rate is split up into income effect and substitution effect is shown in Fig. It makes the consumer indifferent to any of the combinations of goods shown as points on the curve. (5) The consumers tastes, habits and income remain the same throughout the analysis. Now, suppose the individual is given food stamps of Rs. The indifference curve analysis has also been used to explain producer's equilibrium, the problems of exchange, rationing, taxation, supply of labour, welfare economics and a host of other problems. 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. Thus, if a person chooses combination C, this means that he has OL1 amount of leisure time and OM1 amount of income. 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. Nine most important properties of indifference curves are as follows: (1) A higher indifference curves to the right of another represents a higher level of satisfaction and preferable combination of the two goods. 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. The marginal rate of substitution (MRS) is the rate at which some units of an item can be replaced by another while providing the same level of satisfaction to the consumer. Thus ration limit serves as a binding for him and forces him to consume less of good X and more of good Y than he prefers. IC is strictly Convex to origin i.e. Some of the important problems are explained below with the help of this technique. When a curve intersects the budget limit of an individual consumer, it creates an optimal consumption bundle. 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. One possibility is that with the food-stamp subsidy and resultant kinked budget line B1CL2, in Fig. In order to earn income for satisfying his wants for goods and services, he will devote some of his time to do work. The cookie is used to store the user consent for the cookies in the category "Performance". This implies that at higher wage rates, labour supply may be reduced in response to further rise in wage rates. Now, suppose with the introduction of rationing, ration limit R is fixed for good X and R, for good Y. Consider indifference curves IC1 and IC2 in Fig. The superiority of cash grant in terms of its impact on the welfare of the individuals can be explained in a slightly different way. 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.
