In particular, mention may be made of consumer's equilibrium, derivation of the demand curve and the concept of . Choice of other points on income-leisure line MT will show different amounts of leisure, income and work. Since A is on a higher . Since the food stamps are in addition to his initial income OB1 his budget line with food stamps becomes a kinked line B1 CL2. Budget Line: Notes on Budget Line, Space, Changes and Slope. But there are some budget constraints due to the low income of the consumer. These cookies track visitors across websites and collect information to provide customized ads. An indifferent curve is drawn from the indifference schedule of the consumer. It does not store any personal data. It follows that PE is less than RM. Price-Income Line or Budget Line (With Diagram). 11.20), the greater amount of labour L1 is supplied, which is greater than L0. The derivation of supply curve of labour is depicted in 11.18. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Several kinds of subsidies are paid to the individuals these days by the Government for promoting welfare of the people. TOS4. The superiority of cash grant in terms of its impact on the welfare of the individuals can be explained in a slightly different way. Necessary cookies are absolutely essential for the website to function properly. Content Guidelines 2. 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. 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. The consumer is expected to buy any of the two commodities in a combination. Indifference curves are heuristic devices used in contemporary microeconomics to demonstrate consumer preference and the limitations of a budget. 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. 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. 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. If the higher overtime wage rate w represented by the steeper line EK is fixed, the individual is in equilibrium at point H on indifference curve IC2 where he chooses to have OL2 leisure time and OM2 amount of income. The cookie is used to store the user consent for the cookies in the category "Performance". Some of the advantages are: 1. 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. Income OM equals OT multiplied by the hourly wage rate (OM = OT.w) where w represents the wage rate. 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. The indifference curve indicates the various combinations of two goods that yield equal satisfaction to the consumer. 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. Only convex curves will lend to the principles of Diminishing Marginal Rate of substitution. Hence, relief payments in cash are preferable to a food subsidy because they are economically more efficient, giving the relief receipts either a greater gain at the same cost to the Government or the same gain at a lower cost.. (10) The consumer arranges the two goods in a scale of preference which means that he has both preference and indifference for the goods. 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. 2. An indifference curve is a graph that represents the different combinations of two goods that give an individual the same level of satisfaction or utility. Thus, the cash transfer equivalent to the cost of price subsidy has led to the greater increase in welfare or satisfaction of the individual as compared to the price subsidy. We shall explain below only few applications. It's essentially the cost of the next best alternative that has been forgiven.read more play a crucial role in the curve analysis. . Only a convex indifference curve can mean a diminishing marginal rate of substitution of X for K If indifference curve was concave to the origin it would imply that the marginal rate of substitution of X for y increased as more and more of X was substituted, for Y. an indifference curve helps the consumer to determine . 11.20. All combinations give him equal satisfaction. Thus the food subsidy has induced the individual to consume more food than in case of cash payment. If now the Government introduces a rationing for commodity X and fixes a ration of X equal to ORx (At point Rx we have shown a vertical line showing the constraint or ration limit imposed by the rationing fixed at ORx). But ration limit Rx for good X is larger than his optimum or equilibrium consumption quantity of good X. Thus PE, is money value of the subsidy to the individual. 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 helps to compare the satisfaction of different goods/commodities and enables the consumer to attain the equilibrium.

One of the properties of the indifference curve is that it is strictly convex and never concave. 3.Indifference curve shows various possible combinations of two goods that give equal satisfaction to the consumer. Hence the name indifference curve. Under what conditions supply curve of labour (i.e. The greater the fall in marginal rate of substitution, the greater the convexity of the indifference curve. The cookies is used to store the user consent for the cookies in the category "Necessary". 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. However, the final result of the two types of subsidies depends on the value of food stamps relative to preferences and incomes of the individuals whom subsidies are granted. As will be seen from Figure 11.5, as a result of income effect of the indirect tax the consumer moves from point Q3 on indifference curve IC3 to point Q2 on lower indifference curve IC2 and as a result of substitution effect he is further pushed to point Q1 on still lower indifference IC1. An Indifference curve shows potential combinations of two items or commodities that, when bought in any order along the curve, leave the buyer equally well off or satisfied. Further, income is used to purchase goods, other than leisure for consumption. We know that consumers in actual world do not generally buy and consume one good. To do so we take away so much income from the individual that he comes back to the original indifference curve IC1. Share Your Word File 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. 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. However, his preference for those combined products can be arranged in the order of preference. The indifference curve analysis work on a simple graph having two-dimensional. All other variables remain constant. . Share Your Word File As in case of change in price, rise in wage rate has both the substitution effect and income effect. Answer (1 of 7): Indifference curve analysis is very important to the study of economics. Save my name, email, and website in this browser for the next time I comment. The consumer behavior remains constant in the analysis. This is because some part of the income which the individual was spending on food prior to food-stamp subsidy gets released because of the food-stamps being used for its purchase and this released income is spent on non-food items. If a consumer purchases two goods, the budget limitation can be displayed with the help of a budget line on a graph. number of hours worked). We will further show how much K work effort (i.e. Hence IC2 curve gives more satisfaction. Disclaimer Copyright, Share Your Knowledge less work-hours supplied). 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. Now, if no food subsidy was given and therefore the price line was PL1, then for buying OA quantity of food, the individual would have spent PN amount of money. Now, if substitution effect had been larger than income effect, work-hours supplied would have increased as a result of rise in wage rate. Amount of labour L1 is directly plotted against higher wage rate w, in panel (b) of Fig. . Our mission is to provide an online platform to help students to discuss anything and everything about Economics. 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). 11.8 he is at lower indifference curve IC0 indicating his lower level of welfare. 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. The slope of the curve at any given point represents utility for any combination of two goods. TOS 7. However, as seen above, in practice it is difficult to make a plan that will increase the consumption of subsidised food and will not affect the consumption of other goods. We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. 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. We will also demonstrate how the effect of food-stamp subsidy differs from cash subsidy. In our Figure PE = MK (the vertical distance between two parallel lines) and RM is greater than MK. 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. 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. Meaning of Indifference Curve: The indifference curve analysis measures utility ordinally. Thus, the maximum amount of leisure time that an individual can enjoy per day equals 24 hours. In other words, at point Q2 individuals level of welfare is higher than at Q1. 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. 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 utility is expressed in terms of ordinal numbers. If indifference curves were concave or straight lines, the consumer would succumb to monomania, that is, he would buy and consume only one good. 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. Thus, the difference TM (or KQ1) between the two is the amount of money which the individual is paying as the excise duty. This website uses cookies to improve your experience while you navigate through the website. The cookie is used to store the user consent for the cookies in the category "Analytics". Each individual axis indicates a single type of economic goods. Now, the important question is why an indirect tax (an excise duty or a sales tax on a commodity) causes excess burden on the consumer in terms of loss of welfare or satisfaction. The usefulness of the indifference curves: it helps to distinguish between the substitution effects and the incomes effects.

If the amount substituted is imperfect, the marginal rate of substitutionMarginal Rate Of SubstitutionThe 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.read more will be constant. 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. 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. 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. 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. Supply curve of labour shows how an individuals work effort responds to changes in the wage rate. 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. 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. An indifference curve is a graph that represents the different combinations of two goods that give an individual the same level of satisfaction or utility. The Indifference Map refers to a set of Indifference Curves that reflects an understanding and gives an entire view of a consumers choices. But opting out of some of these cookies may affect your browsing experience. 11.19. 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. It Provides a . Answer (1 of 3): The following points highlight the top nine advantages of indifference curve technique over marshallian utility analysis. We cannot predict the specific result purely on theoretical grounds. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. The loss of satisfaction to the consumer on account of the downward movement must be made up by the gain through the rightward movement. It has, however, been empirically observed that when the wage rate is small so that the demand for more income to purchase goods and services is very strong, substitution effect is larger than the income effect so that the net effect of rise in wage rate will be to reduce leisure and increase the supply of labour. Another important result obtained from our above analysis is that even with food stamps programme the individual increases the consumption of all other goods (i.e. 200 he can buy 20 kg of food. Further, he is better off than before as he is now at the higher indifference curve IC2. 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. The budget line is tangent to indifference curve IC2 at point 'E'. (say apples), quantity of another good (say oranges) must fall so that the total satisfaction (utility) remains same. it slopes downward from left to right. The cookies is used to store the user consent for the cookies in the category "Necessary". Thus, he has worked for TL1 hours to earn OM1 amount of income. 8.6. The latter shows the various combinations of the two commodities such that the consumer is indifferent to those combinations. 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. With the imposition of lump sum tax, the price line will shift below but will be parallel to the original price line PL1. 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. Likewise, Professor Scitovsky remarks, one can make a man happier by giving him cash and letting him spend it as he thinks best than by forcing him to take all his relief in the form of one commodity. 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. The slope of the indifference curve measuring marginal rate of substitution between leisure and income (MRSLm ) shows the tradeoff between income and leisure.

We also use third-party cookies that help us analyze and understand how you use this website. If the individual wants to buy more food-grains than B1C, then he will spend some part of his initial income to purchase additional food. 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. 200 he can therefore buy 20 kg of food which is equal to B1C at the given market price. This supply of labour is directly shown against wage rate w0 in panel (b) of Figure 11.18. He now works for TL2 hours per day, TL1 at hourly wage rate w and L1L2 at higher wage rate w. The same argument holds good in this case as developed above in the case of intersection of indifference curves. Also referred to as final products, examples of consumer goods include an Apple cellphone or a box of Oreo cookies. 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. Privacy Policy 8. 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. 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. Second, wage rate is the same irrespective of the number of hours he chooses to work. 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. 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. 8.5 two indifference curves are shown cutting each other at point C. Now take point on indifference curve IC2 and point B on indifference curve IC1 vertically below A. 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. The less the ease with which two goods can be substituted for each other, the greater will be the fall in the marginal rate of substitution. This is directly plotted against the wage rate w0 in panel (b) of Fig. bundles which contain more of both or more of at least one. 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.
