The document defines elasticity of demand as the percentage change in quantity demanded divided by the percentage change in the variable (usually price) that demand depends on. There are different types of elasticity including price, income, cross, and promotional elasticity. Price elasticity of demand expresses how quantity demanded responds to price changes. It is calculated as the percentage change in quantity divided by the percentage change in price. Demand can be perfectly elastic, perfectly inelastic, unitary elastic, elastic (price elasticity over 1), or inelastic (price elasticity less than 1) depending on how much quantity demanded changes relative to the price change.

1. Elasticity refers to the responsiveness or sensitivity of one economic variable to changes in another variable. It is used to measure how demand or supply responds to changes in price.
2. Price elasticity of demand measures the percentage change in quantity demanded of a good in response to a 1% change in its price. Demand can be elastic, inelastic, or unitary elastic depending on its responsiveness to price changes.
3. Price elasticity of supply measures the percentage change in quantity supplied of a good in response to a 1% change in its price. Supply can be elastic, inelastic, or unitary elastic depending on how responsive it is to price changes.Types of price elasticity

This presentation discusses the different types of price elasticity of demand. There are five types: perfectly elastic demand, relatively elastic demand, unitary elastic demand, relatively inelastic demand, and perfectly inelastic demand. Perfectly elastic demand means that demand changes proportionally to any change in price, while perfectly inelastic demand means that demand does not change with price changes. There are several methods used to measure price elasticity of demand quantitatively, including percentage change, total revenue, and geometric methods.Elasticity of demand ppt-best gp

The document discusses the different types of changes in demand. It defines demand and explains the demand function. There are two types of changes in demand: (1) Extension or contraction of demand due to changes in price with other factors remaining the same, which results in movement along the demand curve. (2) Shift in demand due to changes in factors other than price with price remaining the same, resulting in the demand curve shifting up or down. An upward shift represents increasing demand while a downward shift represents decreasing demand.Theory of Demand

Price elasticity of demand measures how responsive consumer demand is to changes in price. It is calculated by taking the percentage change in quantity demanded divided by the percentage change in price. Demand can be elastic, inelastic, perfectly elastic, perfectly inelastic, or unit elastic depending on how much quantity demanded changes relative to price changes. Factors like availability of substitutes, necessity of the product, and proportion of income spent on it affect price elasticity. Understanding price elasticity helps firms set prices to maximize total revenue.Demand analysis

2) The law of demand states that, other things remaining constant, as price increases, quantity demanded decreases. The law of supply states that as price increases, quantity supplied also increases.
3) Market equilibrium occurs where quantity demanded equals quantity supplied. This establishes an equilibrium price where markets clear without surplus or shortage.Price elasticity of demand

It states that the law of supply is that, other things remaining the same, quantity supplied rises with price and falls with lower price. The supply curve slopes upward due to factors like diminishing marginal productivity and profit maximization goals of producers. The determinants of supply include price of the commodity, price of related goods, technology, costs, and government policy. The document discusses individual and market supply schedules and curves, and how movements along and shifts of the supply curve represent changes in quantity supplied and changes in supply, respectively.Theory Of Demand

Microeconomics studies the economic behavior of individuals and firms in making decisions regarding scarce resources. It examines topics at a small scale, such as how people choose what to buy or how many products a company will make. Common areas of microeconomics include supply and demand, consumer theory, game theory, and the analysis of individual budgets, purchases, income, and debt. Microeconomics can be divided into micro statics (relationships between variables in equilibrium), comparative micro statics (comparing equilibriums over time), and micro dynamics (the process of moving between equilibriums).Law of production

This document summarizes two laws of production: the law of variable proportions and the law of returns to scale.
(1) The law of variable proportions states that as variable inputs are increased within fixed inputs, marginal productivity initially increases at an increasing rate until a peak, after which it decreases. It applies in the short run when some inputs are fixed.
(2) The law of returns to scale describes how average and marginal productivity change as all inputs are increased proportionally. It includes the laws of increasing, constant, and diminishing returns.Price elasticity of demand

Price elasticity of demand refers to how responsive the quantity demanded of a good is to changes in its price. There are three methods to measure price elasticity: percentage method, total-outlay method, and geometrical method. The percentage method uses a formula to directly calculate elasticity. The total-outlay method examines how total expenditure changes with price changes to determine if demand is elastic or inelastic. Geometrical representation shows demand curves for different elasticity scenarios like perfectly inelastic, unitary, and perfectly elastic demand. Price elasticity can be classified as zero, less than one, equal to one, greater than one, and infinity depending on how quantity demanded responds to price changes.Lec 18 Elasticity of Supply

Elasticity of Supply
The elasticity of supply can be defined as the degree (measure) of responsiveness in quantity supplied to a change in price.
It is also defined as the percentage change in quantity supplied divided by percentage change in price.
It represents the rate of change in quantity supplied due to a change in its own price.

In economics, the relationship between the quantity of a commodity that producers wish to sell at various prices and the quantity that consumers wish to buy. It is the main model of price determination used in economic theory. The price of a commodity is determined by the interaction of supply and demand in a market. The resulting price is referred to as the equilibrium price and represents an agreement between producers and consumers of the good. In equilibrium, the quantity of a good supplied by producers equals the quantity demanded by consumers.Elasticity of demand

Here are some measures that can help control inflation in India:
1. Monetary policy tightening: The Reserve Bank of India can raise policy interest rates to make borrowing more expensive and reduce money supply growth. This helps contain demand-pull inflation.
2. Fiscal consolidation: The government needs to reduce its fiscal deficit by cutting non-essential spending and increasing tax revenues. Lower fiscal deficit will reduce pressure on money supply.
3. Supply-side measures: The government can take steps to boost agricultural and industrial production through reforms, infrastructure spending, etc. This will increase domestic supply of goods and ease inflationary pressures.
4. Rationalize subsidies: Fuel and food subsidies need to be better targeted to control theirMore Related Content

National income includes only income generated through legal economic activity and received by individuals, excluding undistributed corporate profits. It is measured using indicators like GDP, GNP, NNP, personal income, and disposable income. Developing countries face additional challenges in accurately measuring national income due to large non-monetized sectors, lack of specialization, non-market transactions, and limited data availability.Air conditioning system (automotive)

Price elasticity of demand measures the responsiveness of quantity demanded to a change in price. It is calculated as the percentage change in quantity divided by the percentage change in price. Demand can be perfectly inelastic, relatively inelastic, unitary, relatively elastic, or perfectly elastic depending on how responsive quantity is to price changes. Price elasticity is measured using either the point method or percentage method. Factors like availability of substitutes, nature of the commodity, income spent on it, and habits of consumers determine a good's price elasticity.Elasticity Of Supply And Demand

Elasticity measures the responsiveness of quantity to price changes. It allows economists to compare markets without standardizing units. There are own price elasticities of demand and supply that measure responsiveness of quantity to the good's own price. Demand is more price sensitive when elasticity is further from zero. Total expenditures can increase or decrease with price changes depending on elasticity. Other elasticities include cross price and income elasticities.Elasticity of Demand - Concept and Measurements

Elasticity of demand refers to the percentage change in demand for a commodity in response to a percentage change in factors that affect demand, such as price. Price elasticity of demand specifically measures the responsiveness of quantity demanded to changes in price. There are five degrees of price elasticity: perfectly inelastic, perfectly elastic, less elastic, highly elastic, and unitary elastic demand. The geometric or point method measures elasticity at different points on the demand curve by calculating the ratio of lower to upper segments. Factors like commodity nature, income, substitutes, and time period influence price elasticity. Understanding elasticity is important for international trade, government policymaking, and business decisions.Elasticityof demand

The document discusses the concept of elasticity of demand. It defines elasticity as the responsiveness of quantity demanded to a change in price. There are three main types of elasticities - price elasticity, income elasticity, and cross elasticity. Price elasticity measures the responsiveness of quantity demanded to a change in the price of the good. Income elasticity measures the responsiveness to a change in consumer income. Cross elasticity measures the responsiveness to a change in the price of a substitute or complementary good. The document also discusses factors that influence each type of elasticity, and the importance of understanding elasticities for business decisions.Demand

This document discusses the concept of elasticity in managerial economics. It provides examples of different types of price elasticity of demand including unitary elasticity, elastic demand, inelastic demand, perfectly inelastic demand, and perfectly elastic demand.
For unitary elasticity, the example given is ice cream and beef, where a proportional change in price results in a proportional change in quantity demanded. Elastic demand is exemplified by bananas, where a small price change leads to a larger quantity change. Gasoline is used to illustrate inelastic demand, where a large price change produces only a small quantity change. Insulin and medicines are examples of perfectly inelastic demand, where any price change does not affect quantity. Finally, coal is2Elasticity Analysis.pdf

This document discusses price elasticity of demand. It defines price elasticity as a measure of how responsive the quantity demanded is to changes in price, with all other factors held constant. An elastic demand means a large change in quantity demanded for a small change in price. Inelastic demand means a small change in quantity demanded for a large change in price. The document provides the formula for calculating price elasticity and illustrates examples of perfectly inelastic, unit elastic, and perfectly elastic demand curves. It also discusses how price elasticity relates to total revenue and the factors that influence a good's elasticity, such as availability of substitutes and proportion of income spent.2Elasticity Analysis.pdf

This document discusses price elasticity of demand, including how to calculate it using percentage changes in price and quantity demanded. It explains that elasticity can be used to determine how total revenue will change if price changes, and identifies factors that influence a good's elasticity, such as availability of substitutes. Elasticity of demand can be perfectly inelastic, unit elastic, or perfectly elastic. The document also introduces concepts of cross elasticity of demand and income elasticity of demand.elasticity.pptx

The document discusses various types of elasticity including:
1. Price elasticity of demand which measures the responsiveness of quantity demanded to a change in price. It discusses factors that affect price elasticity and types including elastic, inelastic, unitary, perfectly inelastic, and perfectly elastic demand.
2. Income elasticity of demand which measures responsiveness of demand to a change in income. It can be positive, negative, or zero.
3. Cross price elasticity of demand which measures responsiveness of the demand for one good to a price change in another good.
4. Price elasticity of supply which measures responsiveness of quantity supplied to a change in price. It provides examples ofElasticity of demand

- 2. MEANING OF ELASTICITY OF DEMAND: Term is used to denote a measure of the rate at which demand changes in response to the change in prices. It is the percentage change in quantity demanded divided by the percentage in one of the variables on which demand depends. It is Price elasticity of demand , which is usually referred to as elasticity of Demand.
- 3. TYPES OF ELASTICITY OF DEMAND: Price elasticity Income elasticity Cross elasticity Promotional elasticity
- 4. PRICE ELASTICITY OF DEMAND: Price elasticity of Demand expresses the response of quantity demanded of goods to a change in its price. Definition: ≠Elasticity of demand may be defined as the ratio of the percentage change in demand to the percentage change in price -prof.Lipsey..
- 5. THUS, PRICE ELASTICITY OF DEMAND IS THE RATIO OF PERCENTAGE CHANGE IN AMOUNT DEMANDED TO A PERCENTAGE CHANGE IN PRICE. Price elasticity(Ep)=%change in quantity demanded % change in Price Ep= ^Q xP = ^Q x P Q ^P ^P Q Where, Ep=price elasticity P=Price Q=Quantity ^Q=Change in quantity demanded ^P=Change in Price.
- 6. TYPES/DEGREES OF DEMAND: Perfectly Elastic Demand(E=): In this case the demand for a commodity changes even though there is no change in Price. It implies that with a very small Percentage change in price , the quantity demanded would change indefinitely & so the seller would not change the Price.
- 7. Perfectly Inelastic Demand(E=0): If the demand for a commodity does not change in spite of an increase or decrease in its Price.
- 8. Unitary Elastic Demand(E=1) Price elasticity of demand is unity when the change in demand is exactly proportionate to the change in price. Eg: The Price is Rs.10 &the quantity demanded is 100 units &the total outlay is Rs.1000. and if price increases to Rs.20 & the quantity demanded declines to 50 units , the total outlay is Rs. 1000 In this case demand curve is rectangular hyperbola.
- 9. Elastic Demand(E>1): If the Percentage change quantity demanded is greater than the percentage change in price. Price elasticity of demand is greater than one. Eg: The Price Increases from Rs.10 to Rs.20,quantity demanded declines from 100 units to 40 units.as a result , the total outlay declines from Rs. 1000 to Rs.800.
- 10. on the other hand, if Price declines from Rs.10 to Rs.5 and quantity demanded increases from 100to300 units as a result the total outlay has increased from Rs.1000 to Rs.1500. In this case the price and total outlay are inversely related.
- 11. Inelastic demand(E<1): If the Percentage change in quantity demanded is less than the percentage change in Price . Price elasticity of demand is less than one. Eg: when price increases from Rs.10 to Rs.20& the quantity declines from 100 units to 50 units , the total outlay increases from Rs.1000 to Rs.1500.
- 12. On the other hand if the price declines from Rs.10 to Rs.5 & quantity demanded increases from 100 units to 150 units . the total outlay declines from Rs.1000 to Rs.750 This shows that the price and total outlay are directly related. Because , the quantity demanded changes relatively slower than the change in price.
