If the price goes down just a little, consumers will buy a lot more.

Elasticity of demand refers to price elasticity of demand. It is the degree of responsiveness of quantity demanded of a commodity due to change in price, other things remaining the same. The price elasticity of demand is defined as the percentage change in quantity demanded due to certain percentage change in price. Suppose that price of a commodity falls down from Rs. What is the price elasticity of demand?

Elasticity of Demand: Meaning and Types of Elasticity (explained with diagram)

Price Elasticity of Demand Definition. Price Elasticity of Demand Formula. Types of Price Elasticity of Demand. In other words, it identifies the relationship between price, demand , and how it reacts when prices change. If we take an example of price elasticity of demand — a business may need to know what impact raising its prices will have. It would be pretty pointless in raising prices if profits were to decline. So calculating the price elasticity of its product gives a good indication of how higher prices will impact its bottom line.

This can be calculated using the formula below:. Price elasticity of demand can be calculated by dividing the percent change in demand by the percent change in price. Let us now take an example of price elasticity of demand and how it is calculated.

We must first work out the change in quantity. In this case, it has changed from to From the example above, we reached a price elasticity of demand of However, what does that mean? Well first of all, it is important to highlight that we do not consider negatives.

That means the actual figure is 2 — this is so that the final figure fits within the type of price elasticity. When looking at the results from the calculation, they fall into the following buckets based on the price elasticity of demand. The main types of price elasticity come in two common forms: inelastic demand, and elastic demand — with a third, but uncommon type: unitary demand.

Inelastic demand is where the price elasticity of demand is less than 1, which means that customers are largely unreactive to changes in price. This is because customers do not care too much about the price. Inelastic demand may occur as a result of limited substitute goods. For example, the local supermarket may only offer one type of bread.

The only other place to go is miles away, so there may also be an element of opportunity cost. To get a similar product, the consumer will have to spend time and money on fuel to get there. As a result, the supermarket may be able to raise prices substantially before consumers start going elsewhere. As we can see from the chart above — demand hardly reacts to a change in price.

So although the price has risen by percent, demand has only fallen by 33 percent. Therefore, demand is inelastic because it does not respond significantly to the price. It might be the song from your favourite artist or a new mobile phone — consumers are willing to spend more because it is a one off purchase. Paying a little extra for a one off purchase has a different psychological impact when compared to paying extra for a good that the consumer purchases every day.

Consumers have little choice but to fill their cars up with petrol. So even if the price of petrol doubled, they still need to buy it to get around.

There is simply a lack of substitutes, so they are forced to buy the good no matter the price. The only alternative is just not to drive, which is not really an option for many. For instance, we only need to look at football or baseball games as examples — customers can only buy food and drink available in the stadium. Some products are necessary to live, so consumers have to pay however much it costs. For example, consumers have to pay for their medication no matter what it costs.

Without it, they may fall gravely ill and need hospital treatment. There are also other necessities such as utilities, food, and water that are all necessary to live and which may in some cases be more prone to inelastic demand. Products such as mince pies, turkey, and ice cream are generally seasonal. Consumers eat more ice cream in the summer and more mince pies near Christmas. When a product or service has elastic demand, it means that customers are very responsive to price.

So if the local Pretzel store starts charge an extra 5 cents and it loses half its customers, we can conclude that demand is very elastic. Consumers are unwilling to spend more and therefore go elsewhere instead. Issues such as quality are largely negated in favour of the lowest price. We can consider insurance as a prime example; at least specific types such as car and home insurance. There is little difference between offerings, and comparison websites have become popular for this very reason.

Consumers are extremely price-sensitive and are happy to shop around to find a good deal. As we can see from the chart above, demand is significantly sensitive to price. So although the price has fallen by 20 percent, demand has increased by over percent.

Demand is, therefore, elastic because demand responds significantly to the price. Insurance is a good example. As prices go up, some consumers will look to change to a cheaper provider. Even a few dollars increase can lead to consumers going on the web to look up comparative prices for a similar policy.

When there are many other products available, a higher price for one makes the others more appealing. For example, there are hundreds of types of chocolates and chocolate bars. Any price differentiation beyond the norm can lead to consumers choosing an alternative. If there is no cost associated with switching, it makes the decision to purchase a substitute good more likely; allowing demand to fluctuate more. If prices go up for KitKats, there is no cost applied if you no longer buy one.

So there is no financial penalty for buying a substitute. By contrast, phone contracts do the exact opposite and lock consumers in for up to 2 years. Goods or services that are luxury do not need to be brought, so consumers can be more sensitive to price. Let us take an example. In reality, there are no examples of unitary demand. The reason being is that human demand is non-linear. That is to say that there is not a direct relationship between price and demand.

There are other factors at play such as quality and availability of substitute goods. So although a good may become 10 percent cheaper, many will still prefer product X because it is their favorite.

There are three types of price elasticity: inelasticity, elasticity, and unitary. If a goods demand is elastic, it means that demand for it is extremely reactive to a change in the price.

Key Points Price elasticity of demand measures how consumers react to a change in price. There are five types of price elasticity of demand: perfectly inelastic, inelastic, perfectly elastic, elastic, and unitary.

Price elasticity of demand can be calculated by dividing the percentage change in quantity demanded by the percentage change in price. We value your feeback! Price Elasticity of Demand Formula Price elasticity of demand can be calculated by dividing the percent change in demand by the percent change in price.

Calculating Price Elasticity of Demand Let us now take an example of price elasticity of demand and how it is calculated. There are five types of price elasticity of demand. They are: Perfectly Elastic Demand Elastic Demand Perfectly Inelastic Demand Inelastic Demand Unitary Demand When looking at the results from the calculation, they fall into the following buckets based on the price elasticity of demand.

Let us look at what they mean: 1. Inelastic Demand Inelastic demand is where the price elasticity of demand is less than 1, which means that customers are largely unreactive to changes in price. Factors affecting Inelastic Price Elasticity of Demand 1. Infrequent purchases It might be the song from your favourite artist or a new mobile phone — consumers are willing to spend more because it is a one off purchase.

No substitutes Consumers have little choice but to fill their cars up with petrol. Necessities Some products are necessary to live, so consumers have to pay however much it costs. Seasonal Products such as mince pies, turkey, and ice cream are generally seasonal.

Elastic Demand When a product or service has elastic demand, it means that customers are very responsive to price. Factors affecting Elastic Price Elasticity of Demand 1. Many Substitutes When there are many other products available, a higher price for one makes the others more appealing. Low Switching Costs If there is no cost associated with switching, it makes the decision to purchase a substitute good more likely; allowing demand to fluctuate more.

What is meant by price elasticity of demand? What are the types of price elasticity of demand? Absolute Poverty Definition - Absolute poverty is the state by which an individual is unable to meet their immediate needs.

Price Elasticity of Demand: Definition, Types with Examples

Elasticity is a central concept in economics, and is applied in many situations. Basic demand and supply analysis explains that economic variables, such as price, income and demand, are causally related. Elasticity can provide important information about the strength or weakness of such relationships. There are four types of elasticity, each one measuring the relationship between two significant economic variables. They are:. Price elasticity of demand PED , which measures the responsiveness of quantity demanded to a change in price. PED can be mmeasured over a price range, called arc elasticity, or at one point, called point elasticity.

Price Elasticity of Demand Definition

In the earlier discussion we were able to understand the relationship between demand and price. Thus according to the law of demand there is an inverse relationship between price and quantity demanded, other things remaining the same. These other things which are assumed to be constant are taste or preference of the consumer, income of the consumer, prices of related goods etc.

Examples of demand elasticity other than price elasticity of demand

Elasticities of demand are measures of responsiveness of quantity demanded of a product to different determinants of demand i. The most popular elasticity of demand is the price elasticity of demand. There are three main types of elasticities of demand: the price elasticity of demand so popular that it is generally referred to as simply elasticity of demand , income elasticity of demand and cross elasticity of demand. There are a range of factors which affect quantity demanded either directly or indirectly. Quantity demanded increases if the price of the product decreases and vice versa.

The demand for a product can be elastic or inelastic, depending on the rate of change in the demand with respect to change in price of a product.
