## Factors Affecting Price Elasticity of Demand

For instance, some goods are very , that is, their prices do not change very much given changes in supply or demand, for example people need to buy gasoline to get to work or travel around the world, and so if oil prices rise, people will likely still buy just the same amount of gas. Price discrimination is distinguished from by the more substantial difference in for the differently priced products involved in the latter strategy. This type of demand is an imaginary one as it is rarely applicable in our practical life. If two commodities are perfect substitutes such as red pencil and black pencil and if the price of red pencil rises by 1%, its sale will fall to zero and the demand for black pencils, will be very elastic. An inelastic demand curve shows that an increase in the price of a product does not substantially change the supply or demand of the product. Flatter the slope of the demand curve, higher the elasticity of demand. The degree of necessity of the good A necessity like bread will be demanded inelastically with respect to price.

## #. 19. Different degree of price elasticity of demand.

Demand for many commodities is more elastic. Supply in units 10 15 100 200 As seen in the schedule, the quantity supplied rises by 100% due to a 50% rise in price. Another name given to versioning is menu pricing. Thus revenue depends on the relative magnitude of changes in p and q or on price elasticity of demand. What is the price elasticity of demand? Unit Elasticity: Demand is unit elastic when percentage change in quantity demand and percentage in price are equal.

## Price elasticity of demand

These may be quite targeted, as they are designed to generate specific activity, such as buying more frequently, buying more regularly, buying in bigger quantities, buying new products with established ones, and so on. It must be noted that perfectly elastic supply is an imaginary situation. Commodities which have numerical high elasticities are called luxuries, whereas those with small elasticities are called necessities. This can help the relations between the firms involved. This can also be shown geometrically. The price elasticity of supply is calculated and can be graphed on a demand curve to illustrate the relationship between the supply and price of the good. The behaviour of total outlay in response to price change indicates whether demand is price elastic, unitary elastic or inelastic.

Have students compare the elasticity of the different goods on the website. Students will complete the about inelasticity. This is because coffee and tea are considered good to each other. Relatively inelastic demand has a practical application as demand for many of products respond in the same manner with respect to change in their prices. Price discrimination can also be seen where the requirement that goods be identical is relaxed. However, they are not as elastic as such luxury items as movie tickets because paper towels are considered by many to be a want and they represent a fairly small percentage of a typical grocery budget.

## 5 Degrees of Price Elasticity of Demand

Marshall has termed relatively inelastic demand as elasticity being less than unity. Boulding says that elasticity of demand measures the responsiveness of demand to change in price. Then, have them complete the following activity. In this case, revenue at £1. Thus it is also called zero elasticity. Cross elasticity of demand is an economic concept that measures the responsiveness in the quantity demanded of one good when the price for another good changes.

The range of responses The degree of response of quantity demanded to a change in price can vary considerably. Airlines accomplish this by imposing advance ticketing requirements or minimum stay requirements — conditions that would be difficult for the average business traveler to meet. According to Marshal such elasticity is called greater than unity. In many cases, where the product is marketed to make an attractive gift, the gender of the purchaser may be different from that of the end user. This is particularly widespread in sales to industrial customers, where bulk buyers enjoy higher discounts. Perfectly inelastic demand Inelastic demand means that there is no change in demand whether the price increases or decreases.

In the formula, the numerator quantity demanded of stir sticks is negative and the denominator the price of coffee is positive. Some commodities have more elastic demand while others have relative elastic demand. However, perfectness of anything, including perfectly inelastic supply is considered to be rare or impractical in economy. Thus airlines use pricing strategies designed to fill seats rather than equate marginal revenue and marginal costs. Similar techniques are used in pricing business class airline tickets and premium alcoholic drinks, for example. If the demand for the product of a firm is unitary elastic price change will have no effect on total revenue.

## Explaining Price Elasticity of Demand

If the good represents a small proportion of a person's budget, price changes do not greatly affect the amount purchased. This helped put pressure on airlines to lower fares. Thus, there are bulk discounts, special pricing for long-term commitments, non-peak discounts, discounts on high-demand goods to incentivize buying lower-demand goods, rebates, and many others. Meanwhile, in the recession following the September 11, 2001, attacks on the U. Elastic goods such as restaurant meals, movie tickets, and luxury items usually follow the law of demand and will see a drop in quantity demanded when prices rise. Relatively elastic demand The demand is relatively elastic when it is more than one. The price elasticity of demand, a measure of the responsiveness of quantity demanded to a price change, may cause a change in price to have a small or large impact on quantity demanded.

The reason for this can be found out by examining the budget constraint. Flatter the curve, more is the Elasticity at the point of intersection: In Fig. Hoekman; Aaditya Mattoo; Philip English 2002. The price elasticity of supply for all 3 curves is equal to one. Under the Affordable Care Act, health insurance companies are now required to offer the same premium price to all applicants of the same age and geographical locale without regard to gender. So, we can say that it is the rate or the degree of response in demand to the change in price. Relatively elastic supply When percentage change in quantity supplied is greater than percentage change in price, the condition is known as relatively elastic supply.

Additionally to second degree price discrimination, sellers are not able to differentiate between different types of consumers. Finally, if the quantity purchased changes less than the price say, -5% demanded for a +10% change in price , then the product is termed inelastic. Perfectly Elastic Demand : When a small change in price of a product causes a major change in its demand, it is said to be perfectly elastic demand. Graphically, elasticity can be represented by the appearance of the supply or demand curve. If the good is highly desired with few substitutes it may be more inelastic. However, product heterogeneity, or high fixed costs which make marginal-cost pricing unsustainable in the long run can allow for some degree of differential pricing to different consumers, even in fully competitive retail or industrial markets. .
