# Elastic demand

Demand elasticity helps firms model the potential change in demand due to changes in the price of a good, the effect of changes in prices of other goods, and many other important market factors. A grasp of demand elasticity guides firms toward more optimal competitive behavior and allows them to make precise forecasts of their production needs. Elasticity is the percentage change, which is a different calculation from the slope and has a different meaning. When Elastic demand are at the upper end of a demand curve, where price is high and the quantity demanded is low, a small change in the quantity demanded—even, say, one unit—is pretty big in percentage terms.

A change in price of a dollar is going to be much less important in percentage terms than it would have been at the bottom of the demand curve.

Likewise, at the bottom of the demand curve, that one unit change when the quantity demanded is high will be small as a percentage.

## Price Elasticity Of Demand

So, at one end of the demand curve, where we have a large percentage change in quantity demanded over a small percentage change in price, the elasticity value would be high, or demand would be relatively elastic.

Even with the same change in the price and the same change in the quantity demanded, at the other end of the demand curve the quantity is much higher, and the price is much lower, so the percentage change in quantity demanded is smaller and the percentage change in price is much higher.

That means at the bottom of the curve we have a small numerator over a large denominator, so the elasticity measure would be much lower, or inelastic. Summary Price elasticity measures the responsiveness of the quantity demanded or supplied of a good to a change in its price. It is computed as the percentage change in quantity demanded—or supplied—divided by the percentage change in price. Elasticity can be described as elastic—or very responsive—unit elastic, or inelastic—not very responsive. Elastic demand or supply curves indicate that the quantity demanded or supplied responds to price changes in a greater than proportional manner.

An inelastic demand or supply curve is one where a given percentage change in price will cause a smaller percentage change in quantity demanded or supplied. Unitary elasticity means that a given percentage change in price leads to an equal percentage change in quantity demanded or supplied.

Self-check questions Using the data shown in the table below about demand for smart phones, calculate the price elasticity of demand from point B.Elastic demand is when the percentage change in the quantity demanded exceeds the percentage change in price. That makes the ratio more than one. For example, say the quantity demanded rose 10 percent when the price fell 5 percent.

The Price Elasticity of Demand for Gasoline Would a Gasoline Tax Cause People to Buy Less Gas? In cloud computing, elasticity is defined as "the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible".

Elasticity is a defining characteristic that differentiates cloud .

Feb 19,  · What we're going to think about in this video is elasticity of demand-- tis-sit-tity, elasticity of demand.

And what this is, is a measure of how does the quantity demanded change given a . Price elasticity of demand - PED - is a key concept and indicates the relationship between price and quantity demanded by consumers in a given time period.

The elasticity of supply or demand can vary based on the length of time you care about.
