Classification of Price Elasticity of Demand
1. Price Elastic Demand (% ΔQd > % ΔP) ϵ > 1
If the value of price elasticity coefficient is greater than one in absolute value. This means that a small change in price results to a greater change in quantity demanded.
Goods which are elastic tend to have some or all of the following characteristics:
They are luxury goods
They are expensive and a big % of income e.g. sports cars and holidays
Goods with many substitutes and a very competitive market. E.g. if Simsbury’s put up the price of its bread there are many alternatives, so people would be price sensitive
Bought frequently
Graph:
We say a good is price elastic when an increase in prices causes a bigger % fall in demand. e.g. if price …show more content…
Tap water. For householders, tap water is a necessity, with no alternatives. If the water company increase the cost of water bills, people would keep buying the service. It would have to rise to a very high price before people disconnected their water supply. This is why tap water is regulated.
Diamonds. Bought very infrequently, diamonds are the ultimate luxury with few exact alternatives. You could buy other precious gems, but others may not have the same allure as diamonds. A cut in price wouldn’t increase demand very much.
Peak rail tickets. For commuters who rely on the train to get to work in London, demand will be very inelastic. If price of fares from Surbiton to London increase, demand will only fall by a small amount. The alternatives for commuting into London, such as driving are limited.
Apple iPhones, iPads. The Apple brand is so strong that many consumers will pay a premium for apple products. If the price rises for apple iPhone, many will continue to buy. If it was a less well known brand like Dell computers, you would expect demand to be price elastic.

Price Elasticity of Demand Formula
313 Words  1 PagesThe formula for the price elasticity of demand is as follows (Moffat, 2013): PEoD = (% Change in Quantity Demanded)/(% Change in Price) Thus, with the paint, the price elasticity of demand is as follows: (2035)/35 / (3.503.00) / 3 42.8% / 0.1667 = 2.56 What this means is that for every unit decline in currency, the decline in demand is 156% times that. There are three kinds of elasticity. There is elastic demand, where the elasticity is over 1. There is unitary elastic, where it is at…

Price Elasticity of Demand and Supply
1102 Words  5 Pagesin making price and output decisions. Price Elasticity of Demand The price elasticity of demand measures the sensitivity of the quantity demanded to price. The price elasticity of demand is the percentage change in quantity demanded brought by a 1 percent change in price. The value of price elasticity of demand for a normal good must always be negative, reflecting the fact that demand curves slope downward because of the inverse relationship of price and quantity. The price elasticity…

764 Words  4 PagesJanuary 2008, gasoline prices were $3 a gallon with an increase of 33 percent price of gasoline was $4 a gallon in June 2008. Between the January and June 2008 time period the quantity of gasoline purchased decreased by 3 percent. After gathering the required information, the second step is to calculate the price elasticity of demand (PEoD) for gasoline is to calculate the percentage change in price which is done by using the following formula. [Price NewPrice Old] / Price Old. The numbers plugged…

The Price Elasticity Of Demand
968 Words  4 PagesPrice elasticity of demand is defined as a measure of “the responsiveness or sensitivity of consumers to changes in the price of a good or service” (Thomas & Maurice, 2012, pp. 199). Mathematically, the price elasticity of demand is calculated by dividing the percentage change in quantity demanded by the percentage change in price. Demand is said to be elastic whenever the absolute value of the percentage change in quantity demanded exceeds the percentage change in price, which means the absolute…

Questions On Price Elasticity Of Demand
922 Words  4 PagesASSIGNMENT ANSWERS Question 1 Price Elasticity of demand is the measure of the relationship that exist between a change in the quantity that is demanded for a good and the change in its price. It describes how the good is sensitive to price changes. The formula for PED = % Change in Quantity demanded / % Change in the Price. A product is sad to be price elastic or responsive to price changes when a small change in price causes a more than proportionate change in the demand of the product. On the other…

The Price Elasticity Of Demand
1180 Words  5 PagesDr. Obi In the demand analysis for the product of this particular firm, we have found that the price elasticity of demand is 1.2. This implies that with a 1% rise in price, quantity demanded falls by 1.2%. Therefore, the expenditure on the good remains almost the same. The firm cannot hope to increase market share by decreasing the price. The revenue earned by the firm will remain the same whether it increases or decreases the price as the demand is almost unitary elastic. There…
