Elasticity, Consumer Surplus and Producer SurplusPrice Elasticity of Demand is the degree of responsiveness of demand for product due to a change in the price of that product.-Perfectly inelastic demandInelastic demand vs elastic demand Unit elasticity Perfectly elastic demand Measuring price elasticity of demand: Total revenue method Price per litre (Rs)Quantity demanded Total revenue Elasticity 1.01818Elastic0.92219.80.82721.60.73323.10.64024Unitary0.548240.45823.2Inelastic0.370210.28416.8Measuring price elasticity of demand: Point methodElasticity = percentage change in quantity demanded, between two points divided by percentage change in price between two points.
Numeral Example Midpoint formula ? Types of Elasticity for Demand Price elasticity of demand: Already discussed
Income elasticity of demand: Measures how the quantity demanded of the product responds to a change in income. Cross elasticity of demand: Measures how the quantity demanded of one product responds to changes in the price of another product.

Marginal Utility and DemandAre marginal utility and demand related?
Why consumer pay lower purchase when they want purchase more quantity Demand curve: Marginal Utility = Price of the product Consumer Choice and Budget Constraint Rational Behavior
Clear-cut preference
Budget constraints
Prices are given Utility-Maximizing Rule To Maximize satisfaction, the consumer should allocate his or her money so that the last rupee spent on each product yields the same amount of extra (marginal) utility.
Utility Maximization and Demand Curve
Indifference Curve AnalysisThe budget line: What is attainable; the consumers budget line shows all the combinations of any two products that can be purchased, given the prices of the products and the consumers money income.
Budget line
Indifference Curve Every point on indifference curve represents some combinations of products A and B, and all those combinations are equally satisfactory to the consumer. That is, each combination of A and B on the curve yields the same total utility. Indifference Curve
The Indifference Map
Marginal Rate of substitution (MRS)MRS is the rate at which consumer substitutes one good for the other to remain equally satisfied.
The Slope of Indifference Curve = MRSEquilibrium at Tendency Slope of indifference curve = slope of budget line
Consumers Equilibrium
The Derivation of the Demand Curve
The Cost of ProductionEconomic costs Explicit vs implicit costs Normal profit as a cost
Production in Short runSort run vs Long run Total output Marginal output Average outputThe relationship between input and outputLaw of Diminishing ReturnAs a variable resource (labor) is added to fixed amount of other resources (land and capital), the total product that results will eventually increase by diminishing amounts, reach a maximum, and then decline.
