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 worth noting that price subsidy on a commodity is also generally called excise subsidy. The cookie is used to store the user consent for the cookies in the category "Performance". It means that the price ratio of commodity-1 and commodity-2 should be equal to the marginal rate of substitution of commodity-1 for commodity-2. it slopes downward from left to right. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. 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. 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 above the horizontal line B1C1 the combinations of other goods and food are not attainable when he is given the food stamps of Rs. Plagiarism Prevention 4. 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. 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. These combinations provide the same level of satisfaction and utility to the consumer. You can calculate it by, bundles which contain more of both or more of at least one. This supply of labour is directly shown against wage rate w0 in panel (b) of Figure 11.18. The consumer behavior remains constant in the analysis. Answer (1 of 3): The following points highlight the top nine advantages of indifference curve technique over marshallian utility analysis. 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. 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. The usefulness of the indifference curves: it helps to distinguish between the substitution effects and the incomes effects. That is why at point K in Fig. 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. 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. To break up this wage effect on labour supply, we reduce his money income by compensating variation in income. All other points on the budget line to the left or right of point 'E' will lie on lower indifference curves and thus indicate a . 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. labour supply) L0L2 for leisure. 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. This result is of special importance because supporters of food-stamp subsidy have been emphasizing that food subsidy should not be used to finance any part of nonfood unnecessary items such as liquor. One of the properties of the indifference curve is that it is strictly convex and never concave. 10 per kg. it provides an ordinal measurement of utility. 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. IC is strictly Convex to origin i.e. This is an important feature of an indifference curve. To do so we take away so much income from the individual that he comes back to the original indifference curve IC1. 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. Since A is on a higher . This is directly plotted against the wage rate w0 in panel (b) of Fig. If the individual can work for all the 24 hours in a day, he would earn income equal to OM. less work-hours supplied). When a curve intersects the budget limit of an individual consumer, it creates an optimal consumption bundle. That is, at wage rate w0he supplies TL0 amount of labour. Lump-sum tax has reduced the individuals welfare less than that by the excise duty. (10) The consumer arranges the two goods in a scale of preference which means that he has both preference and indifference for the goods. 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. You can calculate it by, Usually, the combination with the higher satisfaction level is preferred. 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. 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. 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. If indifference curves were concave or straight lines, the consumer would succumb to monomania, that is, he would buy and consume only one good. 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. Budget Line: Notes on Budget Line, Space, Changes and Slope. The marginal rate of substitution shows the consumers preference for one good over another while maintaining the same level of utility. All this means that the two perfect complements are used in a certain fixed ratio and cannot be substituted for each other In Fig. In short, the first condition of the consumer's equilibrium is that the budget or price line should be tangent to the indifference curve. This gives us TM0 as the budget constraint or which in the present context is also called leisure-income constraint. The latter shows the various combinations of the two commodities such that the consumer is indifferent to those combinations. With equivalent food stamp subsidy of B1C the individual has to choose a point which must be on the kinked budget line B1CL2. Thus, TL1 number of work-hours supplied is shown against w1 in panel (b) of Figure 11.18. Consider Fig. 2. What is the shape of IC, when MRS between good X and Y is diminishing? When the wage rate rises to W1 (budget constraint becomes TM1 in panel (a) of Fig. Since the consumer cannot use food stamps to buy non-food items (other goods) he cannot spend more than his initial income OB1 on other goods. 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. 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. Before publishing your Articles on this site, please read the following pages: 1. 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. Also referred to as final products, examples of consumer goods include an Apple cellphone or a box of Oreo cookies. An indifference curve is a graphical representation of various combinations or consumption bundles of two commodities. 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. Therefore, given that the consumer is free to spend money as he likes, with cash grant his new equilibrium position must be to the left of point R on the budget line CD where it will be tangent to the higher indifference curve than IC2. 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 slope of the indifference curve measuring marginal rate of substitution between leisure and income (MRSLm ) shows the tradeoff between income and leisure. He is supposed to rank them in his order of preference and can state if he prefers one combination to the other or is indifferent between them. It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. The cookie is used to store the user consent for the cookies in the category "Other. Analytical cookies are used to understand how visitors interact with the website. Now, the important question is what is the money value of this price subsidy (RM) on food to the individual. As stated above, when two goods are perfect substitutes of each other, the indifference curve is a straight line on which marginal rate of substitution remains constant. We will now explain the consequences if both the commodities X and Y are rationed. As will be seen in Fig. Privacy Policy3. That is, these food stamps cannot be used to buy non-food goods. The preference-maximising point A on indifference curve I 1 shows that . Consider Figure 11.5 where on the X-axis, good X and on the F-axis money is measured. Thus, with the rise in wage rate above W1,labour supply decreases. Further, these stamps cannot be traded or transferred to the other people. (7) An indifference curve is negatively inclined sloping downward. Let us take the case of food subsidy which is given by the Government to help the needy families. read more, theory of exchange, etc. 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. The use of the indifference curve will help to judge the welfare effect of direct and indirect taxes on the individuals. Now, consider Figure 11.10 where it will be seen that ration limit Ry is smaller than consumers optimum consumption of Y as indicated by combination E of the two goods on the budget line BL which has been drawn with his given income and prices of two goods. Hence IC2 curve gives more satisfaction. We will also demonstrate how the effect of food-stamp subsidy differs from cash subsidy. IC2 is the higher indifference curve than IC1. By purchasing OA quantity of food, the individual is spending PT amount of money. Indifference curves are heuristic devices used in contemporary microeconomics to demonstrate consumer preference and the limitations of a budget. 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. Disclaimer Copyright, Share Your Knowledge all of which provide satisfaction to the individual. The curve slopes downward as the consumption of commodity A increases in exchange for commodity B. 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. 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. On the other hand in case of cash subsidy the government provides a lump sum cash income to the consumer. Indifference curves between income and leisure are therefore also called trade-off curves. It does not store any personal data. A higher indifference curve shows a higher level of satisfaction. 11.20), the greater amount of labour L1 is supplied, which is greater than L0. This website uses cookies to improve your experience while you navigate through the website. Microeconomics is a bottom-up approach where patterns from everyday life are pieced together to correlate demand and supply. 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. Thus, his preferences are such that rationing is not actually binding for him. 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. These cookies track visitors across websites and collect information to provide customized ads. This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. Thus, the cash money equivalent of the price subsidy to the individual is less than the cost of the subsidy to the Government.
