What is the relationship between the quantity demanded and the price?

The relationship between the quantity demanded and the price is known as the demand curve, or simply the demand. The degree to which the quantity demanded changes with respect to price is called the elasticity of demand.

What is the proportion to which the quantity demanded changes with respect to price?

The proportion to which the quantity demanded changes with respect to price is called elasticity of demand. A good or service that is highly elastic means the quantity demanded varies widely at different price points. Conversely, a good or service that is inelastic is one with a quantity demanded that remains relatively static at varying price ...

What is the relationship between price and quantity?

An inverse relationship means that higher prices result in lower quantity demand and lower prices result in higher quantity demand.

How does price affect demand?

The price of a good or service in a marketplace determines the quantity that consumers demand. Assuming that non-price factors are removed from the equation, a higher price results in a lower quantity demanded and a lower price results in higher quantity demanded. Thus, the price of a product and the quantity demanded for that product have an inverse relationship, as stated in the law of demand .

A Definition and The Formula

  • All elasticities measure responsiveness. In this case, the two key words are 'price' and 'demand', so the price elasticity of demand measures the responsiveness of the quantity demanded to a given price change. In the last 'topic' we discussed demand at some length. In most cases, the demand for a good rises when the price falls, ceteris paribus. The question is, by how much? Th…

Using The Formula

  • You will only face questions that specifically ask you to calculate an elasticity in multiple-choice papers. Having said that, essay questions often appear where you need to analyse the significanceof certain elasticities. Either way, it is important that you are confident in dealing with this, relatively simple, arithmetic formula.

Calculating The Elasticity

  • Let's start with the easiest questions you might face: At this point, it might be worth reviewing how to calculate percentage changes. Basically, you work out the change, divide this change by the original figure and then multiply the result by 100. Or, if you prefer the algebraic form: So, the percentage change in quantity demanded is -40 (the cha...

Calculating Demand and Price Changes from A Given Elasticity

  • Often, you will face the following type of question: The maths doesn't really get any harder than this in A level economics. That's meant to be a good thing, by the way! The formula has three parts: Ed, %Qd and %P. In the questions where you had to find the value of the elasticity, you were given two of the three parts and asked to find the third. In the question above, exactly the same t…
