Definition
Price elasticity of demand is defined as the measure of responsivenesses in the quantity demanded for a commodity as a result of change in price of the same commodity.In other words, it is the percentage change in quantity demanded as per the percentage change in price of the same commodity. In economics and business studies, the price elasticity of demand (PED) is a measure of the sensitivity of quantity demanded to changes in price. It is measured as elasticity, that is it measures the relationship as the ratio of percentage changes between quantity demanded of a good and changes in its price
Interpretation of elasticity
Value Meaning
n = 0 Perfectly inelastic.
0 > n > -1 Relatively inelastic.
n = -1 Unit (or unitary) elastic.
-1 > n > -∞ Relatively elastic.
n = -∞ Perfectly elastic.
A price drop usually results in an increase in the quantity demanded by consumers
The demand for a good is relatively inelastic when the change in quantity demanded is less than change in price. Goods and services for which no substitutes exist are generally inelastic.

Elasticity and revenue
When the price elasticity of demand for a good is inelastic (|Ed| < 1), the percentage change in quantity demanded is smaller than that in price. Hence, when the price is raised, the total revenue of producers rises, and vice versa.
When the price elasticity of demand for a good is elastic (|Ed| > 1), the percentage change in quantity demanded is greater than that in price. Hence, when the price is raised, the total revenue of producers falls, and vice versa.
When the price elasticity of demand for a good is unit elastic (or unitary elastic) (|Ed| = 1), the percentage cha...

The difference between the change from records to CDs and the switch from DVDs to Blu-ray is that people can now download media, and that’s an option that Sony can’t make go away. Heck, the content side of the company can’t afford to ignore users that want to download content either. Maybe Sony will eventually drop Blu-ray prices, but by then it may be too late. This is not a company swimming in profit. In its 2008 annual report, reported net profits were under 4.2 percent. That’s almost down in the profitability territory of resellers. Of course that might explain the drive for premium prices. If the company makes that little profit when they charge a lot, what color would the ink be if prices were more competitive?
Inelastic demand means that an increase or decrease in price will not significantly affect demand for the product. In spite of the rising prices for the Blue Jays tickets, fans were expected to turn out in large numbers. This inelastic demand for the tickets can be attributed in large part of the fact that their teams plays so well in 1998, and another factor is that the Blue Jays fan could never stay away from their team. Another inelastic demand for the Blue Jays tickets is that there is no other locally substitute team.
Elasticity is the responsiveness of demand or supply to the changes in prices or income. There are various formulas and guidelines to follow when trying to calculate these responses. For instance, when the percentage of change of the quantity demanded is greater then the percentage change in price, the demand is known to be price elastic. On the other hand, if the percentage change in demand is less than then the percentage change in price; Like that of demand, supply works in a similar way. When the percentage change of quantity supplied is greater than the percentage change in price, supply is know to be elastic. When the percentage change of quantity supplied is less then the percentage change in price, then the supply then demand is known to be price inelastic.
4. The elastic is the increase of price of the eggs. Since the price of the eggs had increased, there would be a decrease in demand. The inelastic is the decrease of price of the eggs where buyers will buy more eggs because of price reduction which increases demand. The possible change in the egg producer’s revenue given the price increase that took place in the market will result in a reduction of revenues. Increasing the price of the eggs will result in less sales of the eggs which will decrease revenue of the eggs.
Normally, if the quantity demanded of a good is very responsive to a change in the good's price, the good is considered to be elastic (Investopedia.com, 2015). Unlike to a product, in which the quantity demanded of the good is very responsive to a change in the product's price, is an inelastic good. Goods that are inelastic show little response in the quantity demanded to a change in price (Jay Kaplan, 2002).
Looking at price elasticity we see that the absolute value is greater than one. This means that if the company decided to increase the price of the product there would be a decrease in quantity sold. From the data we can conclude that the price elasticity is elastic. “When demand is elastic—that is Ed >;1—a given percentage increase (decrease) in price is more than offset by a larger percentage decrease (increase) in quantity sold” (McGuigan, Moyer, and Harris, 2014). Since, the product is somewhat elastic an increase in price will result in lower quantity
Price Elasticity is the measure in responsiveness of consumers to changes in the price of a product or service. The evaluation and consideration of this measure is a useful tool in firms making decisions about pricing and production, and in governments making decisions about revenue and regulation. “Price Elasticity is impacted by measurable factors that allow managers to understand demand and pricing for their product or service; including the availability of substitutes, the consumer budgets for the product or service, and the time period for demand adjustments.” The proper consideration of Price Elasticity allows managers to set pricing such that the effect on Total Revenue is predictable and adjustments to production are timely. The concept of Price Elasticity is employed in the management of commercial firms and government.
To the consumer purchasing a can of common table salt, it is small expense with limited consumption. The demand will not increase much with increase in income. If price of salt decreased the quantity demanded would not drastically increase as a person can only consume only so much salt. This suggests inelastic demand.
In a market demand, there are two markets, product markets and resource markets. Anytime a market exists, there are buyers and sellers. The buyers of a good or service are called demanders. A demand is best defined as the willingness and ability to buy a good at a range of prices (Cowen, Tabarrok 27). The law of demand states that there is always an inverse relationship between the price of a good and the quantity demanded. When the price of a good is high, a lower quantity will be demanded by the buyer of that good. It is also true that if the price of a good is low, the greater quantity will be demanded. For this illustration, I will use the market for Ben & Jerry's Ice Cream storefront. Assume that the high price of ice cream at Ben & Jerry's was selling $12 per scoop. We can assume that the quantity demanded for ice cream will be low. But as the price of Ben & Jerry's Ice Cream per scoop drops further to $7, $6, or $1, ceteris paribus, more consumers will be able and willing to afford Ben & Jerry's Ice Cream. According to Nancy
The law of demand states that if everything remains constant (ceteris paribus) when the price is high the lower the quantity demanded. A demand curve displays quantity demanded as the independent variable (the x-axis) and the price as the dependent variable (the y-axis). http://www.netmba.com/econ/micro/demand/curve/
When demand is elastic as with Coca Cola products price changes affect total revenue. When the price increases revenue decreases and when the price decreases revenue increases. For Coca Cola if they notice a decrease in revenue they would offer products at a discount to increase revenue. They do this quite often with sales such buy 2 20 oz. bottles for $3 instead of the normal $1.89 each price
Example, certain cancer fighting drugs can have perfrect inelastic demand. In these cases the demand stays relatively the same regardless of the price. Some specific branded medications do not have any competitors or generic substitutes. In some cases cancer patients have no choice but to buy the medication if they know it can help them beat the disease. On the other hand, consumers may be loyal to a certain brand and may become insensitive to price changes, resulting in more inelastic demand. In some extreme cases governmental agencies may step in if they discover that price gouging is taking place. Inelastic demand can be witnessed in the consumer electronics products industry as
Demand is "the quantity of a commodity that will be required at any given price over some given period of time". "For the majority of the goods and services, experience shows that the quantity demanded will increase as the price falls." (Stanlake 155) This characteristic can be shown by a demand curve. A demand curve is a graphical representation of the data in table with values of demand called a demand schedule. A good that is in greater demand do to income increases is known as a normal good. A inferior good is a good that is in less demand even though the income increases. When this situation occurs the demand curve is positive sloping. A giffen good is a special type of inferior good where demand increases when price increases. The graph below is a sample demand curve, where the demand schedule for the quantity of toilet paper demanded is graphed.
Elasticity is also prominent to businesses. The price elasticity of demand is very important for companies to determine the price of their products and their total sales and revenue. Newell showed that by cutting the price of the Left 4 Dead game in half to $25 during a Valve promotion, its sales increased by 3000 percent (Irwin, 2009)viii.
The market price of a good is determined by both the supply and demand for it. In the world today supply and demand is perhaps one of the most fundamental principles that exists for economics and the backbone of a market economy. Supply is represented by how much the market can offer. The quantity supplied refers to the amount of a certain good that producers are willing to supply for a certain demand price. What determines this interconnection is how much of a good or service is supplied to the market or otherwise known as the supply relationship or supply schedule which is graphically represented by the supply curve. In demand the schedule is depicted graphically as the demand curve which represents the amount of goods that buyers are willing and able to purchase at various prices, assuming all other non-price factors remain the same. The demand curve is almost always represented as downwards-sloping, meaning that as price decreases, consumers will buy more of the good. Just as the supply curves reflect marginal cost curves, demand curves can be described as marginal utility curves. The main determinants of individual demand are the price of the good, level of income, personal tastes, the population, government policies, the price of substitute goods, and the price of complementary goods.
Types of goods will help us determine whether demand for cars is elastic or inelastic. If a good is considered to be a luxury rather than a necessity, the greater is the price elasticity of demand (McConnell & Brue, 2004). Cars can be deemed as necessary due to a need for transportation. Other types of cars can be classified as luxury. A person who needs to be able to get from one place to another will have the need for a car. An old vehicle may suffice. In such a scenario, buying a brand new car is more likely to be a luxury rather than a necessity. If car prices go up, people are more inclined to just keep driving their old vehicles. In essence, the cars already on the road would serve as substitutes for new cars. However, over a longer period of time, old cars tend to wear out and the elasticity of demand for vehicles is less.
