It will be seen from Figure 11.16 that the given income-leisure line MT is tangent to the indifference curve IC2 at point E showing choice of OL1 of leisure and OM1 of income. Price-Income Line or Budget Line (With Diagram). When the consumer repeatedly substitutes or consumes one good over another, the marginal rate of substitution diminishes. (3) The consumer possesses complete information about the prices of the goods in the market. Suppose to begin with the wage rate is w0 and if all the available hours OT are used to do work, OM0 money income is earned. 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. Let us consider commodities B1 and B2. The consumer is rational to maximize the satisfaction and makes a transitive or consistent choice. less work-hours supplied). Thus income provides satisfaction indirectly. 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. Your Mobile number and Email id will not be published. This cookie is set by GDPR Cookie Consent plugin. In the curve, the quantity consumed by B2 will compensate for the increase in the amount consumed by B2. And this indifference in prices defines the opportunity costs. Since the consumer gets an equal preference for all bundles of goods, they are indifferent about any two combinations on the curve. Thus, as compared to the situation prior to food-stamp subsidy, he is on higher indifference curve showing a greater level of satisfaction or welfare and consuming greater quantities of food and other goods. A customer's marginal utility is the satisfaction or benefit derived from one additional unit of product consumed. You also have the option to opt-out of these cookies. 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. Now, suppose with the introduction of rationing, ration limit R is fixed for good X and R, for good Y. 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. Leisure time can be used for resting, sleeping, playing, listening to music on radios and television etc. (6) He prefers more of X to less of Y or more of Y to less of X. it provides an ordinal measurement of utility. 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. The cookies is used to store the user consent for the cookies in the category "Necessary". Let us suppose that the individual has OP money income. 11.20. Lump-sum tax has reduced the individuals welfare less than that by the excise duty. It may, however, be noted that on theoretical grounds it cannot be predicted which effect will be stronger. In panel (a) on joining points Q, R and S we get what is often called wage-offer curve which is similar to price-consumption curve. Now suppose that wage rate rises to w1 with the result that income-leisure constraint line rotates to TM1. 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. As will be seen in Fig. MRS between income and leisure equals the wage rate (w) that is, the market exchange rate between the two. 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. This implies that at higher wage rates, labour supply may be reduced in response to further rise in wage rates. 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). 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. 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.

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. 200 per week which he can spend on food alone. The assumptions of the ordinal theory are the following: (1) The consumer acts rationally so as to maximise satisfaction. With the imposition of lump sum tax, the price line will shift below but will be parallel to the original price line PL1. This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. 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. With TM1 he reaches his old equilibrium position at point H where he supplies TL1 work-hours. 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. An indifference curve is a graph showing combination of two goods that give the consumer equal satisfaction and utility. Necessary cookies are absolutely essential for the website to function properly. You are free to use this image on your website, templates, etc., Please provide us with an attribution link. Now, with TM1 as new income-leisure constraint line, the individual is in equilibrium at point H at which he supplies TL1 work-hours of labour which are less than TL0. 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. 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. Jack is satisfied with 1 unit of cloth and 8 units of books. The marginal rate of substitution shows the consumers preference for one good over another while maintaining the same level of utility. Consumer goods are the products purchased by the buyers for consumption and not for resale. 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. Before publishing your Articles on this site, please read the following pages: 1. An indifference curve shows all combinations of goods that provide an equal level of utility or satisfaction. 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 is depicted in Figure 11.17 where at the equilibrium point E a steeper leisure-income line EK than MT has been drawn. You are free to use this image on your website, templates, etc., Please provide us with an attribution linkHow to Provide Attribution?Article Link to be HyperlinkedFor eg:Source: Indifference Curve (wallstreetmojo.com). 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. 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. You also have the option to opt-out of these cookies. Authorized users may be able to access the full text articles at this site. It can slope or bend backward too which implies that at a higher wage rate, the individual will supply less labour (i.e. The indifference curve indicates the various combinations of two goods that yield equal satisfaction to the consumer. TOS 7. 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. 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. How the effect of rise in wage rate is split up into income effect and substitution effect is shown in Fig. 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. Thus, if a person chooses combination C, this means that he has OL1 amount of leisure time and OM1 amount of income. Alternatively, the slope of the curve indicates the marginal rate of substitution between two goods. This is an important feature of an indifference curve. 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. 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. Under what conditions supply curve of labour (i.e. That is, income is earned by sacrificing some leisure. Pen and ink, right shoe and left shoe, automobile and petrol sauce and hamburger, type writer and typists are some examples of perfect complements. Share Your PPT File. 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. The utility is expressed in terms of ordinal numbers. This means that a part of food stamp subsidy has been indirectly used for financing the purchases of non-food commodities. The degree of convexity of an indifference curve depends on the rate of fall in the marginal rate of substitution of X for Y. The same argument holds good in this case as developed above in the case of intersection of indifference curves. Property I. Indifference curves slope downward to the right: This property implies that an indifference curve has a negative slope. 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). 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. 11.4 . Complements are thus those goods which are used jointly in consumption so that their consumption increases or decreases simultaneously. Similarly, if a country has food surpluses and wants to dispose them of, then the food subsidy to the needy families will be the ideal measure to increase the consumption of food-grains and thereby to dispose of the food surpluses. It makes the consumer indifferent to any of the combinations of goods shown as points on the curve. We also use third-party cookies that help us analyze and understand how you use this website. In its analysis, core principles of microeconomics are involved. Property II: Indifference curves are convex to the origin: Another important property of indifference curves is that they are usually convex to the origin. The preference-maximising point A on indifference curve I 1 shows that . We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that youve provided to them or that theyve collected from your use of their services. 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. An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. Usually, the combination with the higher satisfaction level is preferred. An indifference curve is a downward sloping convex line connecting the quantity of one good consumed with the amount of another good consumed. GCD210267, Watts and Zimmerman (1990) Positive Accounting Theory A Ten Year Perspective The Accounting Review, Subhan Group - Research paper based on calculation of faults, Density function, CDF, and final offer arbitration game, CFA Inst - Risk Profiling through a Behavioral Finance Lens. The importance of indifference curve analysis to neoclassical microeconomic consumer theory can hardly be overstated. He now works for TL2 hours per day, TL1 at hourly wage rate w and L1L2 at higher wage rate w. In particular, mention may be made of consumer's equilibrium, derivation of the demand curve and the concept of . 200. The shaded region bounded by the budget line BL and the coordinate axes represents market opportunity set from which the consumer can make a choice of the two commodities. 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. 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). The ordinal utility theory or the indifference curve analysis is based on the assumptions as discussed above. The cookie is used to store the user consent for the cookies in the category "Performance". 10 per kg., then with Rs. 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. You can calculate it by, 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. The meeting of two indifference curves at a point will also lead us to an absurd conclusion. 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. Therefore, RM is also greater than PE. At the old price (before the excise duty was imposed), he could purchase ON quantity of good X for PT amount of money. . It does not store any personal data. The following situations may occur: In conclusion, Jack has the same level of satisfaction and utility in both situations as a consumer. We shall explain below only few applications.

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. An indifference curve has a negative slope, i.e. bundles which contain more of both or more of at least one. (say apples), quantity of another good (say oranges) must fall so that the total satisfaction (utility) remains same. . The cookie is used to store the user consent for the cookies in the category "Analytics". Thus, the difference TM (or KQ1) between the two is the amount of money which the individual is paying as the excise duty. The curve slopes downward as the consumption of commodity A increases in exchange for commodity B. It is thus clear that as a result of the imposition of excise duty, the individual has shifted from a higher indifference curve IC3 to a lower one IC1, that is, his level of satisfaction or welfare has declined. Choice of other points on income-leisure line MT will show different amounts of leisure, income and work. This cookie is set by GDPR Cookie Consent plugin. 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. 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. IC2 is the higher indifference curve than IC1. For instance, if price of food is Rs. 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. 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. Prior to grant of any subsidy, and given his budget line B1L1 the individual is in equilibrium at point E1 on indifference curve IC1. Save my name, email, and website in this browser for the next time I comment. Without this type of analysis, economists would be unable to predict certain behaviors . These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. That is why at point K in Fig. We have taken only one schedule, but any number of schedules can be taken for the two commodities. In the diagram, IC1 and IC2 are the two indifference curves. Consumer Surplus = Maximum Price to be paid willingly Actual Paid Price. Under price or excise subsidy the Government pays a part of the price of a good and allows the consumer to buy as many units of the good as he desires at the sub-sidised price. 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. This website uses cookies to improve your experience while you navigate through the website. The theory of consumption is based on the scale of preference and the ordinal ranks or orders of one's preferences. Suppose now that Government levies an excise duty (an indirect tax) on good X. An indifference map between income and leisure is depicted in Figure 11.14 and has all the usual properties of indifference curves. This is directly plotted against the wage rate w0 in panel (b) of Fig. In this optimal situation, income- leisure trade off (i.e. This diagram shows an example corner solution where the optimal bundle lies on the x-intercept at point (M,0).
