Elasticity of demand refers to the sensitivity of quantity demanded with respect to changes in another outside factor and is a measure of the responsiveness of one economic variable to another. In economics, the elasticity of demand for a certain good or service is represented by the demand
In economics law of supply and demand states that all things being equal, is the price of something increases the demand will drop. This is generally true, however, in a few special cases, demand reaches a point where it will not change regardless of price movement. Examples of inelastic demand include the least amount of inferior quality (low-cost) food that is required to sustain a population. Insulin is one of the good examples of inelastic demand. Prices may increase for this product; customers will not hesitate to engage in a transaction, especially when it involved a matter of life and death.
Therefore, normal goods possess positive income elasticity. The quantity of normal necessities demanded will rise with the revenue but at a measured speed than that of luxury goods. This phenomenon is due to the fact that consumers will opt to buy more extravagant goods and services rather than more of the necessities with their improved incomes (Haque 18). During a time period of improved incomes, the demanded quantity for luxurious commodities will rise at a faster rate than the demanded quantity of necessities. The demanded quantity of luxury products in response to variations in income is very sensitive.

Price elasticity of demand is a term in economics often used when discussing price sensitivity. The formula for calculating price elasticity of demand is: Price Elasticity of Demand = % Change in Quantity Demanded / % Change in Price Measurement of Price Elasticity of Demand There are three methods for measuring elasticity of demand. Outlay method Point method Arc Method Total Outlay Method Total outlay method, also known as total expenditure method of measuring price elasticity of demand was developed by Professor Alfred Marshall. According
DEFINITION Income elasticity is the responsiveness of the demand for a good when there is a variation in consumer income. When income changes the demand we have for a certain goods changes. In other words how much demand of a particular good rise or decline when your own income increases or decreases. An increase in income, with other factors fixed such as prices fixed, causes consumers to alter their choice of goods. FORMULA Income elasticity can be measured by the proportionatal change in quantity demanded by the proportionatal change in income.
Price Elasticity of Demand for Alcohol Price elasticity of demand measures the responsiveness of quantity demanded of a good to a change in price. It gives the indication whether a good is elastic (large change in Qd) or inelastic (small change in Qd). Alcohol is a habit forming good, meaning that consumption patterns will almost remain constant with a change in price. As shown in figure 6, increasing the price due to a tax from Pe to Pc will only result in a small decrease in quantity demanded (Q to Q1) due the inelastic nature of alcohol. Because of this, an increase in taxation of alcoholic beverages will not reduce consumption patterns of this good by a large amount and thus the imposition of tax on alcoholic beverages will benefit the government by increasing government
If the price of soda is $1 then we get the following quantity Q = 10 – 8(1) Q = 2 So, the quantity demanded at price of $1 is 2 units Elasticity of demand can be defined as the responsiveness of quantity demanded of a particular commodity because of a change in its price, in other words elasticity of demand is the percentage change in the quantity demanded of a good due to one percent change in its price, ceteris paribus. As solved earlier we know that at a price of $1 quantity demanded of the can is 2. Now if the price of the can were $0. 75 then the quantity demanded would have been, Q = 10 – 8(0.75) Q = 4 At Price (P) = $1, Quantity demanded (Q) is 2 units At Price (P) = $0.75, Quantity demanded (Q) is 4 units Elasticity of demand (Ed) = change in quantity * P Change in price Q = 2.00 * 1 0.75 2 = 1.33 The elasticity of demand of soda is 1.33 Since we get the elasticity of more than 1 this means that demand changes more with respect to change in price and hence we can conclude that the demand of soda is perfectly
Economists define change in quantity demand to mean only the change in quantity demand of a good that is brought about by a change in the price of that good. They define change in demand to mean a shift in the entire demand curve either to the left or right. Change in demand cause shifts to the right when demand increase, and demand cause shifts to the left when demand
Equilibrium price is the price where the quantity of goods supplied is similar to the quantity of the demanded goods (Thomas & Maurice, 201). In detail, when plotted on a graph, equilibrium is the point at which the demand curve and the supply curve intersect. Simultaneously, equilibrium quantity is where quantity demanded is similar to the quantity supplied. If the market dynamics change and the price fall below the equilibrium level, the quantity demanded will be much higher than the quantity supplied. There are two possible outcomes, a shortage will occur, or there will be excess demand for the product.
