    • Consumer Equilibrium under Indifference Curve Analysis 1. Introduction to Indifference curve analysis
    • Consumer Equilibrium under Indifference Curve Analysis1. Introduction to Indifference curve analysis • Ordinal means- Can be compare with each other- 1St , 2nd , 3rd etc. • Ordinal Utility analysis - Utility can compare but can not be measure. • Popularized by J.R. Hicks and R.G.D. Allen • Used the tool named Indifference Curve • Known as Indifference curve approach of utility analysis
    • Consumer Equilibrium under Indifference Curve Analysis1. Introduction to Indifference curve analysis Assumptions Indifference Curve Analysis a) Consumer is rational or Rationality b) Utility is ordinal c) Consistence in choice If A > B, then never become B > A 4. Consumer’s Preference is Transitive: If A > B and B > C, then A > C 5. Diminishing Marginal Substitution of goods: 6. Dependent Utility 7. A Large bundle of goods preferred to small bundle
    • Consumer Equilibrium under Indifference Curve Analysis II. Assumptions to explain equilibrium of the consumer
    • Consumer Equilibrium under Indifference Curve AnalysisII. Assumptions to equilibrium of the consumerTo Explain the consumers equilibrium the following assumption is there1. The consumer has Indifference Map of good X and Good Y2. The consumer have a fixed money income which are spend on X and Y3. The Prices of good X –Px and good Y – Py are given4. Good are homogenous
    • Consumer Equilibrium under Indifference Curve Analysis III. Indifference Map and Budget Line of consumer
    • Consumer Equilibrium under Indifference Curve AnalysisIII. Indifference Map and Budget Line of consumer A graph showing a whole set of indifference curves is called an indifference map. An indifference map, in other words, is comprised of a set of indifference curves. Each successive curve further from the original curve indicates a higher level of total satisfaction.
    • Consumer Equilibrium under Indifference Curve AnalysisIII. Indifference Map and Budget Line of consumer A budget line or price line represents the various combinations of two goods which can be purchased with a given money income and assumed prices of goods". Income (Y)= 60 Price of Biscuit (Px) = 6 Price of Coffee(Py) = 12 Combination Biscuit Coffee A 10 0 B 8 1 C 6 2 D 4 3 E 2 4 F 0 5
    • Consumer Equilibrium under Indifference Curve Analysis IV. Consumer’s Equilibrium or Maximization of Satisfaction
    • Consumer Equilibrium under Indifference Curve AnalysisIV. Consumer’s Equilibrium or Maximization of Satisfaction "The term consumer’s equilibrium refers to the amount of goods and services which the consumer may buy in the market given his income and given prices of goods in the market, that give maximum satisfaction to consumer". The aim of the consumer is to get maximum satisfaction from his money income. Given the price line or budget line and the indifference map:

Consumer’s Equilibrium or Maximization of Satisfaction "The term consumer’s equilibrium refers to the amount of goods and services which the consumer may buy in the market given his income and given prices of goods in the market". The aim of the consumer is to get maximum satisfaction from his money income. Given the price line or budget line and the indifference map:
    • Consumer Equilibrium under Indifference Curve AnalysisIV. Consumer’s Equilibrium or Maximization of Satisfaction "A consumer is said to be in equilibrium at a point where the price line is touching the highest attainable indifference curve from below"

    • Consumer Equilibrium under Indifference Curve AnalysisIV. First order and Second order condition for consumer Equilibrium
    • Consumer Equilibrium under Indifference Curve AnalysisIV. First order and Second order condition for consumer Equilibrium Thus the consumer’s equilibrium under the indifference curve theory must meet the following two conditions: First order condition : A given price line should be tangent to an indifference curve or marginal rate of satisfaction of good X for good Y (MRSxy) must be equal to the price ratio of the two goods. i.e. MRSxy = Px / Py Slop of IC = Slop of Budget Line Second order condition : The second order condition is that indifference curve must be convex to the origin at the point of tangency.
    • Consumer Equilibrium under Indifference Curve AnalysisIV. First order and Second order condition for consumer Equilibrium First order condition : Necessary Condition (1) Budget Line Should be Tangent to the Indifference Curve: A given price line should be tangent to an indifference curve or marginal rate of satisfaction of good X for good Y (MRSxy) must be equal to the price ratio of the two goods. i.e. MRSxy = Px / Py Slope of the Price Line to be Equal to the Slope of Indifference Curve: Price of X / Price of Y = MRS of X for Y Slop of Budget Line = Slop of IC
    • Consumer Equilibrium under Indifference Curve AnalysisIV. First order and Second order condition for consumer Equilibrium Second order condition : Sufficient Condition The second order condition is that indifference curve must be convex to the origin at the point of tangency. Indifference Curve Should be Convex to the Origin at the point of Tangency
    • Consumer Equilibrium under Indifference Curve AnalysisV. Income Effect: Income consumption Curve a) ICC of Normal Good b) ICC of Inferior good c) Luxury good
    • Consumer Equilibrium under Indifference Curve AnalysisV. Income Effect: Income consumption Curve The Income effect in economics can be defined as the change in consumption resulting from a change in real income. If the prices of goods, tastes and preferences of the consumer remains constant and there a change in his income, it will directly affect consumer’s demand. This effect on the purchase due to change in income is called the income effect.
    • Consumer Equilibrium under Indifference Curve AnalysisV. Income Effect: Income consumption Curve The Income Consumption Curve show how income effect on the quantity consumed of the good

    • Consumer Equilibrium under Indifference Curve AnalysisV. Income Effect: Income consumption Curve a) ICC of Normal Good
    • Consumer Equilibrium under Indifference Curve AnalysisV. Income Effect: Income consumption Curve a) ICC of Inferior good The good which is purchased less with the increase in income is called inferior good. Rice is inferior Wheat is inferior
    • Consumer Equilibrium under Indifference Curve AnalysisV. Income Effect: Income consumption Curve ICC - good X is Inferior and good Y is Normal Good Y ICC - good Y is inferior and good X is Normal Good X
