important properties of indifference curve (with curve diagram) economics discussion important properties of indifference curve (with curve diagram) article. You can learn more about the standards we follow in producing accurate, unbiased content in our. What Is Inelastic? I'll try to explain this concept by contradiction. Given the combination of Lilly’s personal preferences, as identified by her indifference curves, and Lilly’s opportunity set, which is determined by prices and income, B will be her utility-maximizing choice. With this distribution of the two commodities consumer A is on indifference curve A4 while consumer B is on indifference curve B5. But Fisher’s model says, instead, that consumption is based on the resources the consumer expects to have over his lifetime.

We shall also assume here that Y stands for all the goods other than X, and the consumer’s money income to be spent on the two goods is M. We shall discuss the effects of the taxes with the help of Fig. These cookies track visitors across websites and collect information to provide customized ads. It is a tool that is often used in mathematics and the natural sciences to understand and visualize the behavior of a system. After reading this article you will learn about: 1. Microeconomics vs. Macroeconomics Investments. Along with the budget line are shown the three indifference curves from Figure 1. If they could cross, it would create large amounts of ambiguity as to what the true utility is. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. If there were no food subsidy the pensioner would have to spend AK of his income to buy 0X2 units of food. If the graph lies on a curve or line, it suggests that the consumer has almost no preference for any product, because all of the products deliver the same kind of satisfaction or utility to the consumer. Samaira’s indifference can be analysed with the following graphical representation of her indifference curve. So far in the text, we have described the level of utility that a person receives in numerical terms. For example, in the diagram below there are four indifference curves, each one representing a different set of indifference points … Economists have often been criticized for their assumption that people are rational. The numerical slope of the budget line is: The budget constraint of the consumer states that the present value of consumption in the two period should be equal to that of the income of the two periods. The curves that are farther away from the origin represent higher levels of satisfaction as they have larger combinations of X and Y. Let us now see how consumption responds to an increase in income. Indifference curves may be used to analyse the effects of an income subsidy and a price subsidy upon the utility level of the consumer. Webimportance of indifference curve with diagram 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. What is Lilly’s utility-maximizing choice? We shall first examine this constraint in some detail. The lesson of this analysis is that consumption depends on the present value of current and future income i.e., on present value of income which is. Since the consumer is a saver in period 1, we have, C’1 < Y1 and C’2 > Y2, i.e., the point D would lie upward towards left of point A. Most economic textbooks build upon indifference curves to introduce the optimal choice of goods for any consumer based on that consumer’s income. If the consumers exchange x for y so that they arrive at the distribution denoted by R (consumer A giving away YAY’A of commodity y in exchange for XAX’A of commodity x), consumer A will reach a higher welfare situation (moving from indifference curve A4 to the higher one A6) while consumer B retains his initial level of satisfaction (both Z and R lying on the same indifference curve B5). A single indifference curve concerns only one level of satisfaction. Indifference Curves in Economics: What Do They Explain? The two sets of indifference curves, being of opposite curvature, have points of tangency which form the so-called Edge-worth’s contract curve (0A0B in figure 2.27). The cookie is used to store the user consent for the cookies in the category "Performance". (4) The prices of the two goods are given. In Fig. Now, the consumer has three options to spend … Let us also note that the variable S can represent either saving or borrowing (negative saving) and equations (6.131) and (6.132) hold in both cases. In period 2, this amount accumulates to 5 x 1.1 = 5.5 (Rs). We may break up this total effect into a substitution effect and an income effect. A collection bundle is a bundle that maximizes the consumer’s total utility, given the consumer’s budget constraints. For example, points A and B sit on the same indifference curve Um, which means that they provide Lilly with the same level of utility. Since the point A (Y1 Y2) is a common point on both the lines, the budget line would rotate now clockwise about the point A from L1M1 to L2M2 as r rises. So, the consumer is said to be indifferent between the combinations located on Indifference Curve ‘IC 1 ’. You also have the option to opt-out of these cookies. Indifference Curves between: Goods, Bads and Neuters (with curve diagram) The direction of preference in this case is upward and to the left. As illustrated above on the indifference curve map, the farther out from the origin, the more utility the individual generates while consuming. The supply curve is vertical. We do this using indifference curves. 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. The in-kind subsidy budget line, however, would remain the same as ACB1. How Do I Differentiate Between Micro and Macro Economics? Content Guidelines 2. Reviewing your elementary microeconomics, draw a diagram of some indifference curves. the one denoted by H, they will both be better off, reaching higher indifference curves (A5 and B6 respectively) as compared to their initial positions at Z. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Assume, as before, that in the base period the consumer has income Y0 and chooses basket q0, spending on it all his income ∑ q0p0 = Y0. The effects of a supplementary income policy: Assume that the government considers granting to the pensioner a supplementary income which will enable him to reach the higher welfare level implied by indifference curve I2. Return to the situation of Lilly’s choice between paperback books and doughnuts. Elasticity vs. Inelasticity of Demand: What's the Difference? We use cookies to personalise content and ads, to provide social media features and to analyse our traffic. Every action that people take indicates a preference, not indifference. It explains consumer behaviour in terms of his preferences or rankings for different combinations of two goods, say X and Y. Every level of utility will have its own indifference curve. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Here, with cash subsidy net of tax, the consumer is in equilibrium at the point G which is the point of tangency between the cash subsidy, net of tax, budget line A2B2 and IC2. Since, IC2 is a lower curve than IC3, consumer’s level of satisfaction will be adversely affected by the income tax, but since IC2 is a higher curve than IC1 his well-being will not be as adversely affected as done by the excise tax. Most people would prefer to increase the quantity or quality of the goods and services they consume. In the graph below, point A illustrates the tangency condition the utility curve has with the budget line constraint. 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. The formula used in economics for constructing an indifference curve is: Different values of c correspond to different indifference curves, so if we increase our expected utility, we obtain a new indifference curve that is plotted above and to the right of the previous one. There are several types of curve maps, including scatter plots, line graphs, and bar graphs. Each axis represents one type of economic good. Furthermore the quantity of food in this case (0X3) is smaller than the quantity which would be bought under a food subsidy programme (0X2). This cookie is set by GDPR Cookie Consent plugin. Figure 2. Here L1M1 is the consumer’s initial budget line and D (C1, C2) is his initial equilibrium point on the indifference curve IC2.

Thus, Lilly’s preferences will include an infinite number of indifference curves lying nestled together on the diagram—even though only three of the indifference curves, representing three levels of utility, appear in Figure 1. Sign in Register; … For example, a young boy might be indifferent between possessing two comic books and one toy truck, or four toy trucks and one comic book, so both of these combinations would be points on an indifference curve of the young boy. In order to derive the consumer’s budget constraint we have to combine equations (6.131) and (6.132) and thereby we obtain. The indifference curve analysis measures utility ordinally. So period-1 consumption would be C1 = Y1 + Y2/1+r. In microeconomic theory, an indifference curve generally refers to a graph that illustrates different levels of utility, or satisfaction, of a consumer who has been presented with assorted combinations of goods. The point A (Y1, Y2) lies on the budget line L1M1. The indifference curve technique has come as a handy tool in economic analysis. The indifference curve Um has four points labeled on it: A, B, C, and D (see Figure 1). The supply curve is vertical. Which shows that the consumer is better off if the Laspeyres price index is smaller than the income index? These cookies ensure basic functionalities and security features of the website, anonymously. Because the consumer can borrow and lend between periods, the timing of the income is irrelevant to how much is consumed today or tomorrow. (5) The consumer’s tastes, habits and income remain the same throughout the analysis. It is evidenced by figures D, E, and F having decreased marginal utility. The supply curve is horizontal. We shall see that the typical consumer is better off with an income tax than with a comparable excise tax on a single commodity. We may show this result on a graph using indifference-curves analysis. 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. On the other hand, if he spends all his money income on Y, he would have OA of Y plus he would be able to buy an amount of X with the subsidy which is equal to BB1 or AC. Since, at the optimum point or the point of tangency, the numerical slope of the IC is equal to that of the budget line, and since, the former is equal to MRS of C) for C2 and the latter is equal to 1 + r, the consumer’s optimum or equilibrium point is characterised by: MRC1 for C2 = 1 + r (6.35). It is the locus of the point … The cookie is used to store the user consent for the cookies in the category "Analytics". Because people are constrained by a limited budget, they cannot purchase everything. The income-leisure line becomes kinked at e, and the new equilibrium of the individual is at e’ on indifference curve I4, showing that he will increase his working hour (by L1L2) and earn a higher income (0M2 > 0M1). Share Your PPT File. The indifference curve technique has come as a handy tool in economic analysis. Since IC2 is a higher curve than IC1, the price subsidy increases his well-being but since IC2 is lower than IC3, his well-being will not improve as much as in the case of cash subsidy.
