REACTION PAPER By Elizabeth Orendain-Dela Cruz The Elasticity of Wants Alfred Marshall’s Principles of Economics (1890) Elasticity is a way to measure how the change in one thing (price) causes change in another (demand). Understanding elasticity of demand is valuable in knowing the dynamic response of supply and demand in a market. Such understanding will enable an enterprising person (businessman and/or consumer) to achieve a favorable effect (higher revenue/best value of one’s money) or avoid

DEMAND CURVES Shows how much buyers of the product want to buy at each price possible. Vertical axis: price Horizontal axis: annual demand Downward sloping: the higher the price, the less consumers want to buy. SUBSTITUTES: increase of price of one product makes consumers buy more of the other product (demand increases) COMPLEMENTS: increase of price of one product makes consumers buy less of the other (demand decreases) Change in price-> movement along the demand curve Change

by a lot. There are many possible reasons for this phenomenon. Buyers might be able to easily substitute away from the good, so that when the price increases, they have little tolerance for the price change. Maybe the buyers don't want the good that much, so a small change in price has a large effect on their demand for the good. Figure %: Elastic Demand If demand is very inelastic, then large changes in price won't do very much to the quantity demanded. For instance, whereas a change of 25

thoroughly explain elasticity. You are expected to cover issues such as: a. What is it? Elasticity is how the demand or supply curve’s change to a change in the product. Whether it be price, quantity or another factor in the market. There are different elasticity calculations that can be used. Price elasticity of demand is the % change in quantity demanded / % change in price. Price elasticity of supply is the % change in quantity supplied / % change in price. Income elasticity of demand is the

Elasticity of demand is the degree to which demand for a good or service varies with its price. Elasticity of demand is seen most with confectionary and other non-essentials such as cars and appliances. Sales go up as prices go down and as prices go up sales go down. Cross-price elasticity measures the responsiveness of demand for a good that occurs in response to a percentage change in the price of another good. Complements are goods with a negative cross of elasticity demand. These goods are

Topic 2: Elasticity One motivation for studying elasticity is so that firms will know how their revenue might change in response to various price changes. Certainly firms are interested in setting prices in such a way to increase their revenue. Let total revenue be price multiplied by quantity (TR = P . Q). Consider the following demand curves. If we raised the price, would total revenue increase or decrease? Price INELASTIC (like the letter I) Demand Quantity

John Scott ECON212: Principles of Microeconomics December 1, 2013 Phase 2 Individual Project Professor Reddy Urimindi The Price Elasticity of Demand is used to measure how the rate of response of quantity demanded changes due to a price increase or decrease. The formula used to compute the Price Elasticity of Demand (PEoD) is: PEoD = (% Change in Quantity Demanded) / (% Change in Price). To calculate the % change in quantity demanded, we use the formula: QDemand(NEW) - QDemand(OLD)

Professor Chavarria CTU Online Author Note Unit 2 Individual Project What is the price elasticity of demand? The price elasticity of demand is a measure of the relationship between a change in the quantity demanded of a particular good and a change in it’s price. Price elasticity of demand is often used when discussing price sensitivity. The formula for calculating price elasticity is % change in quantity demanded / % change in price. What is elastic and inelastic demand? Elastic

Practice Questions and Answers from Lesson I-7: Elasticity Practice Questions and Answers from Lesson I-7: Elasticity The following questions practice these skills: Use the midpoint method for calculating percent change. Compute price elasticity of demand. Identify elastic and inelastic demand according to the price elasticity of demand. For elastic demand, apply the negative relation between price and revenue. For inelastic demand, apply the positive relation between price and revenue
