## What Is Price Elasticity?

❶It may also be defined as the ratio of the percentage change in demand to the percentage change in price of particular commodity. On the other hand, if the price of cloth rises many households will not afford to buy as much quantity of cloth as before, and therefore, the quantity demanded of cloth will fall.

Generally any change in price will have two effects: For inelastic goods, because of the inverse nature of the relationship between price and quantity demanded i.

But in determining whether to increase or decrease prices, a firm needs to know what the net effect will be. Elasticity provides the answer: The percentage change in total revenue is approximately equal to the percentage change in quantity demanded plus the percentage change in price. One change will be positive, the other negative. As a result, the relationship between PED and total revenue can be described for any good: Hence, as the accompanying diagram shows, total revenue is maximized at the combination of price and quantity demanded where the elasticity of demand is unitary.

It is important to realize that price-elasticity of demand is not necessarily constant over all price ranges. The linear demand curve in the accompanying diagram illustrates that changes in price also change the elasticity: PEDs, in combination with price elasticity of supply PES , can be used to assess where the incidence or "burden" of a per-unit tax is falling or to predict where it will fall if the tax is imposed.

For example, when demand is perfectly inelastic , by definition consumers have no alternative to purchasing the good or service if the price increases, so the quantity demanded would remain constant. Hence, suppliers can increase the price by the full amount of the tax, and the consumer would end up paying the entirety. In the opposite case, when demand is perfectly elastic , by definition consumers have an infinite ability to switch to alternatives if the price increases, so they would stop buying the good or service in question completely—quantity demanded would fall to zero.

As a result, firms cannot pass on any part of the tax by raising prices, so they would be forced to pay all of it themselves. In practice, demand is likely to be only relatively elastic or relatively inelastic, that is, somewhere between the extreme cases of perfect elasticity or inelasticity.

More generally, then, the higher the elasticity of demand compared to PES, the heavier the burden on producers; conversely, the more inelastic the demand compared to PES, the heavier the burden on consumers. The general principle is that the party i. Among the most common applications of price elasticity is to determine prices that maximize revenue or profit. If one point elasticity is used to model demand changes over a finite range of prices, elasticity is implicitly assumed constant with respect to price over the finite price range.

The equation defining price elasticity for one product can be rewritten omitting secondary variables as a linear equation. Constant elasticities can predict optimal pricing only by computing point elasticities at several points, to determine the price at which point elasticity equals -1 or, for multiple products, the set of prices at which the point elasticity matrix is the negative identity matrix.

The fundamental equation for one product becomes. Excel models are available that compute constant elasticity, and use non-constant elasticity to estimate prices that optimize revenue or profit for one product  or several products. In most situations, revenue-maximizing prices are not profit-maximizing prices. For example, if variable costs per unit are nonzero which they almost always are , then a more complex computation of a similar kind yields prices that generate optimal profits.

In some situations, profit-maximizing prices are not an optimal strategy. For example, where scale economies are large as they often are , capturing market share may be the key to long-term dominance of a market, so maximizing revenue or profit may not be the optimal strategy. Various research methods are used to calculate price elasticities in real life, including analysis of historic sales data, both public and private, and use of present-day surveys of customers' preferences to build up test markets capable of modelling such changes.

Alternatively, conjoint analysis a ranking of users' preferences which can then be statistically analysed may be used. This approach has been emprirically validated using bundles of goods e. Though PEDs for most demand schedules vary depending on price, they can be modeled assuming constant elasticity. For suggestions on why these goods and services may have the PED shown, see the above section on determinants of price elasticity.

Definition: The Elasticity of Demand is a measure of sensitiveness of demand to the change in the price of the commodity. Determinants of Elasticity of Demand Apart from the price, there are sever Apart from price, there are several factors that influence the elasticity of demand.

### Privacy FAQs

Price elasticity of demand has four determinants: product necessity, how many substitutes for the product there are, how large a percentage of income the product costs, and how frequently its purchased, according to Economics Help.

If the factors of production can be easily moved from one use to another, it will affect elasticity of supply. The higher the mobility of factors, the greater is the elasticity of supply of the good and vice versa. (iv) Changes in marginal cost of production. Determinants of Price Elasticity of Supply A numeric value that measures the elasticity of a good when the price changes.-availability of materials - The limited availability of raw materials could limit the amount of a product that can be produced.

Determinants of Price Elasticity of Demand. Various factors influence the price elasticity of demand. Here are some of them: 1. Substitution Effect: If a product can be easily substituted, its demand is elastic, like Gap's jeans. If a product cannot be substituted easily, its demand is inelastic, like gasoline. 2. The three elasticity determinants--availability of substitutes, time period of analysis, and proportion of budget--affect, or determine, the values of the price elasticities of demand and supply. The key to these determinants is the ability to respond to price changes. If buyers and sellers can respond more easily, then the respective demand.
