It is thus clear that for an individual supplier of labour income effect and substitution effects work in opposite directions. An indifference curve can neither be horizontal line nor an upward sloping curve. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". But the above principle regarding the programme of subsidised food, subsidised housing etc. Without this type of analysis, economists would be unable to predict certain behaviors . 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. Consumer goods are the products purchased by the buyers for consumption and not for resale. As a result of the rise in price of good X, the price line rotates to a new position PL2 which is tangent to indifference curve IC1 at point Q1. AB is such line obtained after reducing his money income by compensating variation. 8.8. An indifference curve is a downward sloping convex line connecting the quantity of one good consumed with the amount of another good consumed. Examples of goods that are perfect substitutes are not difficult to find in the real world. Thus, the maximum amount of leisure time that an individual can enjoy per day equals 24 hours. These cookies will be stored in your browser only with your consent. 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. Also referred to as final products, examples of consumer goods include an Apple cellphone or a box of Oreo cookies. 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). (7) An indifference curve is negatively inclined sloping downward. Since A is on a higher . Assumptions of Indifference Curve. labour supply) L0L2 for leisure. 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. 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. Thus, the cash money equivalent of the price subsidy to the individual is less than the cost of the subsidy to the Government. Therefore, with subsidy the individual will face the price line PL2 where OL1 = L1 L2. One possibility is that with the food-stamp subsidy and resultant kinked budget line B1CL2, in Fig. With this extra cash transfer equal to RM (-PC), the budget-line will shift to the right to the position CD in Fig. The curves that are farther away from the origin represent higher levels of satisfaction as they have larger combinations of X and Y. Thus, in Figure 11.5, imposition of an equivalent lump-sum or income tax, the consumer moves from the equilibrium position Q3 on indifference curve IC3 to the new position Q2 on indifference curve IC2 which represents the income effect. 11.3 the individual maximises his satisfaction at point E2 where his budget line is tangent to indifference curve IC2. 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. In other words, if the Government wants to raise a given amount of revenue whether it will be better to do so by levying a direct tax or an indirect tax from the view point of welfare of the individuals. Welcome to EconomicsDiscussion.net! Welcome to EconomicsDiscussion.net! Now, suppose the individual is given food stamps of Rs. 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. 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. 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. Besides, a lower price of food due to price subsidy on it induces the consumer to substitute food for other goods causing greater consumption of food as compared to the scheme of lump-sum cash grant which have no such substitution effect and permits free choice of goods to the individual according to his own preference. This is a substitution effect of the rise in wage rate tends to reduce leisure and increase labour supply (i.e. Privacy Policy3. 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. Your Mobile number and Email id will not be published. Since the food stamps are in addition to his initial income OB1 his budget line with food stamps becomes a kinked line B1 CL2. Necessary cookies are absolutely essential for the website to function properly. 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. In order to earn income for satisfying his wants for goods and services, he will devote some of his time to do work. An important application of indifference curves is to judge the welfare effects of direct and indirect taxes on the individuals. 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. To break up this wage effect on labour supply, we reduce his money income by compensating variation in income. Our assumption regarding diminishing MRSxy and the convexity of indifference curves is based upon the observation of actual behaviour of the normal consumer. This trade-off means how much income the individual is willing to accept for one hour sacrifice of leisure time. Irish-born British economist Francis Ysidro Edgeworth first proposed this two-dimensional graph, also known as the iso-utility curve. It comprises individual choices, marginal utilityMarginal UtilityA customer's marginal utility is the satisfaction or benefit derived from one additional unit of product consumed. Thus, the difference TM (or KQ1) between the two is the amount of money which the individual is paying as the excise duty. 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. 11.19 that income effect is stronger than substitution effect so that the net result is reduction in labour supply by L0L1 work-hours. The consumer is rational to maximize the satisfaction and makes a transitive or consistent choice. Hence, the curve obtained is always convex. Now, the important question is what is the money value of this price subsidy (RM) on food to the individual. We shall explain below only few applications. This shows with rise in wage rate from w0 to w1 resulting in leisure becoming relatively expensive, he substitutes work (i.e. Where the X-axis indicates one commodity (Cloth) and Y-axis refers to another good (Book). 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. The cookie is used to store the user consent for the cookies in the category "Other. . Thus, if a person chooses combination C, this means that he has OL1 amount of leisure time and OM1 amount of income. Consumer Surplus = Maximum Price to be paid willingly Actual Paid Price 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. He is also satisfied with 2 units of cloth and 4 units of books. 3.Indifference curve shows various possible combinations of two goods that give equal satisfaction to the consumer. Now, we can bring together the indifference map showing ranking of preferences of the individual between income and leisure, and the income-leisure line to show the actual choice of leisure and income by the individual in his equilibrium position.

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). An indifferent curve is drawn from the indifference schedule of the consumer. Image Guidelines 5. In other words, up to wage rate w0 labour supply curve slopes upward and beyond that it starts bending backward. It shows the consumers preference for one good over another only if it is equally satisfying. . 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. In the case of any consumer, the utility refers to gain from the consumption of two commodities. An indifference curve is a graphical representation of a combined products that gives similar kind of satisfaction to a consumer thereby making them indifferent.Every point on the indifference curve shows that an individual or a consumer is indifferent between the two products as it gives him the same kind of utility. 1.). Here, we understand that all three products resting in the indifferent curve give him the same satisfaction. The maximum amount of time available per day for the individual is 24 hours. This diagram shows an example corner solution where the optimal bundle lies on the x-intercept at point (M,0). In this article we will discuss about Indifference Curves. Effect of Subsidies to Consumers: Price Subsidy Vs. Cash Subsidy: An important application of indifference curves is to analyse with its aid the effect of subsidies to the consumers. For instance, a child might be indifferent while having a toy, two comic book, four toy trucks and a single comic book. Further, income is used to purchase goods, other than leisure for consumption. Indifference curves between income and leisure are therefore also called trade-off curves. Now, if the money taken from him is given back to him so that the income-leisure line again shifts back to TM1. In India also food stamp programme has been suggested in recent years as an anti-poverty measure. You consent to our cookies if you continue to use our website. 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 may, however, be noted that on theoretical grounds it cannot be predicted which effect will be stronger. In other words, at point Q2 individuals level of welfare is higher than at Q1. Theindifference curve in economicsexamines demand patterns for commodity combinations, budget constraints and helps understand customer preferences. 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. 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. MRS between income and leisure equals the wage rate (w) that is, the market exchange rate between the two. The cookie is used to store the user consent for the cookies in the category "Performance". 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. 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. As noted above, combination H is not available under food stamp subsidy because food stamps cannot be used to purchase other goods. This means for most of the recipients, food stamp programme has the same effect as a cash subsidy. This means that a part of food stamp subsidy has been indirectly used for financing the purchases of non-food commodities. Since an indifference curve represents those combinations of two commodities which give equal satisfaction to the consumer the combinations represented by points A and C will give equal satisfaction to the consumer because both lie on the same indifference curve IC2. Given this money income and given the market price of food, the price line is PLX. Thus, with the rise in wage rate above W1,labour supply decreases. The cookies is used to store the user consent for the cookies in the category "Necessary". less work-hours supplied). (With Diagram) Hence, consumers will demand more goods when prices are less. The technique of indifference curves has been used not only to explain consumers behaviour and demand but also to analyse and explain several other economic problems. it helps to compare the satisfaction of different goods/commodities and enables the consumer to attain the equilibrium. In this case with cash subsidy the individual spends more than his initial income OB1 on other goods. As one moves along a straight-line indifference curve of perfect substitutes, marginal rate of substitution of one good for another remains constant. The Derivation of Demand Curves from Indifference Curves on JSTOR. 1., that is, price of rupee one is Re. 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 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. 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. Thus the cost of giving subsidies to consumers is always greater than the money equivalent of the subjective gain to the consumers. With the budget line BL and the rationed quantity Rx he will be at point E which lies at lower indifference curve IC0. The relationship between marginal utility and demand curve is an important concept in economics that helps to explain how consumers make decisions about what to purchase and at what price. Content Guidelines 2. it provides an ordinal measurement of utility. 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. 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. Thus, with the rise in wage rate, supply of labour has decreased by L0L1. With equivalent food stamp subsidy of B1C the individual has to choose a point which must be on the kinked budget line B1CL2. Jack is satisfied with 1 unit of cloth and 8 units of books. Privacy Policy 8. Likewise, the combinations B and C will give equal satisfaction to the consumer; both being on the same indifference curve IC1. 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.
