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. Meaning of Indifference Curve 2. 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.

As explained above in Fig. Thus, with the rise in wage rate above W1,labour supply decreases. Straight-line indifference curves of perfect substitutes are shown m Fig. 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. Since the food stamps are in addition to his initial income OB1 his budget line with food stamps becomes a kinked line B1 CL2. It does not store any personal data. 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 difference between the chosen plan of action and the next best plan is known as the opportunity cost. It can slope or bend backward too which implies that at a higher wage rate, the individual will supply less labour (i.e. These cookies will be stored in your browser only with your consent.

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. 11.20), the greater amount of labour L1 is supplied, which is greater than L0. An indifference curve can neither be horizontal line nor an upward sloping curve. 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. It is the income that serves as a binding on his consumption choice and not the ration limit. Combination L contains more of both goods X and Y than combination M on IC1. In other words, besides analysing consumers demand, indifference curves have several other applications. 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. Since all the combinations give the same amount of satisfaction, the consumer prefers them equally. 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. 11.19. 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. . 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. 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. When the consumer repeatedly substitutes or consumes one good over another, the marginal rate of substitution diminishes. It allows the consumer to buy within a given budget, i.e., within their current income. In this case, therefore, B1C, will be equal to 20 kg. Thus, in this case, rationing is actually binding for the consumer and reduces his welfare. 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. 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. With equivalent food stamp subsidy of B1C the individual has to choose a point which must be on the kinked budget line B1CL2. A customer's marginal utility is the satisfaction or benefit derived from one additional unit of product consumed. 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. 2. A higher indifference curves to the right of another represents a higher level of satisfaction and preferable combination of the two goods. Thus, the difference TM (or KQ1) between the two is the amount of money which the individual is paying as the excise duty. 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. The indifference curve analysis measures utility ordinally. 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. But it should be noted that in the second possible case the consumption of food is more under the food stamp subsidy programme than, in case of cash subsidy. Required fields are marked *. This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. In order to earn income for satisfying his wants for goods and services, he will devote some of his time to do work. But the above principle regarding the programme of subsidised food, subsidised housing etc. Some of the advantages are: 1. Thus the indifference curve I4 indicates a higher level of satisfaction than I3 which, in turn, is indicative of a higher level of satisfaction than I2 and so on. Disclaimer Copyright, Share Your Knowledge As explained above, with the given wage rate and given trade-off between income and leisure the individual chooses to work for TL1 hours per day. 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. Lump-sum tax has reduced the individuals welfare less than that by the excise duty. When the indifference curve is convex to the origin, MRS diminishes as more of X is substituted for K. We therefore conclude that indifference curves are generally convex to the origin. Indifference curve must be convex to the origin: 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. Now consider Figure 11.7 where ration limit is fixed at Rx which lies to the left of L. This ration limit reduces or truncates his market opportunity set (i.e. 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. 1. 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. It indicates that the slope of the curve is negative. Answer (1 of 3): The following points highlight the top nine advantages of indifference curve technique over marshallian utility analysis. In panel (a) of this figure it will be seen that at the wage rate w0(w0= OM0/OT), the wage line or income-leisure line is TM0 and the individual is in equilibrium at point Q where he chooses OL0 leisure time and works for TL0 hours. By clicking Accept, you consent to the use of ALL the cookies. If indifference curves were concave or straight lines, the consumer would succumb to monomania, that is, he would buy and consume only one good. 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. 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. 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. She could also get the same level of utility at point Y, skiing just 1 day and spending 5 days horseback riding. (With Diagram) Hence, consumers will demand more goods when prices are less. Since A is on a higher . Before publishing your Articles on this site, please read the following pages: 1. The indifference curve slopes down from left to right on the graph. 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. Share Your Word File 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. We have taken only one schedule, but any number of schedules can be taken for the two commodities. The theory of consumption is based on the scale of preference and the ordinal ranks or orders of one's preferences. In other words, at point Q2 individuals level of welfare is higher than at Q1. AB is such line obtained after reducing his money income by compensating variation. The indifference curve analysis work on a simple graph having two-dimensional. Cookies help us provide, protect and improve our products and services. An indifference curve has a negative slope, i.e. 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. Economists have adopted the principles of. Further, income is used to purchase goods, other than leisure for consumption. Here we discuss the properties of the indifference curve and how to analyze it, along with examples and assumptions. All this means that the two perfect complements are used in a certain fixed ratio and cannot be substituted for each other In Fig. 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. Under what conditions supply curve of labour (i.e. 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. TOS4. This supply of labour is directly shown against wage rate w0 in panel (b) of Figure 11.18. The imposition of a lump-sum tax (or any income tax) does not affect the prices of goods because it is not levied on any saleable goods. One possibility is that with the food-stamp subsidy and resultant kinked budget line B1CL2, in Fig. In the above image, the combination outside the budget line (S) represents the one beyond the income. 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. What is the shape of IC, when MRS between good X and Y is diminishing? 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. Content Filtrations 6. In this article we will discuss about Indifference Curves. 8.6. Your email address will not be published. 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. Since all consumption bundles give an equal amount of utility, the consumer is indifferent to all combinations. It provides equivalent satisfaction and utility levels for the consumer. If combination A is equal to combination C in terms of satisfaction, and combination B is equal to combination C, it follows that the combination A will be equivalent to B in terms 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. We will explain and compare the effects of two types of subsidies, price subsidy and lump sum cash grant, on consumers welfare. These combinations provide the same level of satisfaction and utility to the consumer. In other words, up to wage rate w0 labour supply curve slopes upward and beyond that it starts bending backward. It is evident from Fig. Budget Line: Notes on Budget Line, Space, Changes and Slope. 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, with the rise in wage rate, supply of labour has decreased by L0L1. The usefulness of the indifference curves: it helps to distinguish between the substitution effects and the incomes effects. (6) He prefers more of X to less of Y or more of Y to less of X. This is an important feature of Indifference Curve. The Indifference Map refers to a set of Indifference Curves that reflects an understanding and gives an entire view of a consumers choices. The meeting of two indifference curves at a point will also lead us to an absurd conclusion. 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. 1., that is, price of rupee one is Re.

Perfect complementary goods are used in a certain fixed ratio. 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. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. The greater the amount of this sacrifice of leisure, that is, the greater the amount of work done, the greater income an individual earns.

This is directly plotted against the wage rate w0 in panel (b) of Fig. Thus, his preferences are such that rationing is not actually binding for him. 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. Login details for this Free course will be emailed to you. An important application of indifference curves is to judge the welfare effects of direct and indirect taxes on the individuals. 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. The same argument holds good in this case as developed above in the case of intersection of indifference curves. The cookie is used to store the user consent for the cookies in the category "Other. The greater the fall in marginal rate of substitution, the greater the convexity of the indifference curve. 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).

However, the more important and relevant case of rationing is depicted in Figure 11.8. Consumer Surplus = Maximum Price to be paid willingly Actual Paid Price. 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. Since at the given market price of food, he can buy ,C amount of food with the food stamps of Rs. 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. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. 11.20. An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. 11.3 the individual maximises his satisfaction at point E2 where his budget line is tangent to indifference curve IC2. 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. 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. . Second, wage rate is the same irrespective of the number of hours he chooses to work. Now suppose that wage rate rises to w1 with the result that income-leisure constraint line rotates to TM1. The assumptions of the ordinal theory are the following: (1) The consumer acts rationally so as to maximise satisfaction. But ration limit Rx for good X is larger than his optimum or equilibrium consumption quantity of good X.
