The amount that customers demand is affected by price (Ped). However, it is also affect by the incomes of consumers. This leads onto another important elasticity – the income elasticity of demand (often shortened to Yed). Show
Income elasticity of demand measures the relationship between a change in quantity demanded for good X and a change in real income. The formula for calculating income elasticity is: % change in demand divided by the % change in income Most products have a positive income elasticity of demand. So as consumers' income rises more is demanded at each price. 1.Normal necessities have an income elasticity of demand of between 0 and +1 for example, if income increases by 10% and the demand for fresh fruit increases by 4% then the income elasticity is +0.4. Demand is rising less than proportionately to income. 2.Luxury goods and services have an income elasticity of demand > +1 i.e. demand rises more than proportionate to a change in income – for example a 8% increase in income might lead to a 10% rise in the demand for restaurant meals. The income elasticity of demand in this example is +1.25. However, there are some products (economists call them "inferior goods") which have a negative income elasticity of demand, meaning that demand falls as income rises. Typically inferior goods or services tend to exist where superior goods are available if the consumer has the money to be able to buy it. Examples include the demand for cigarettes, low-priced own label foods in supermarkets and the demand for council-owned properties. The income elasticity of demand is usually strongly positive for
In contrast, income elasticity of demand is lower for
The elasticity of demand measures the changes in quantity demanded to changes in various parameters like the price of the product, income of the consumer, or the price of a competing product or substitute. The elasticity of demand can be classified into three types:
Income elasticity of demand measures the responsiveness of the consumer’s demanded quantity of specific products or multiple products in response to changes in his income level. When there is a change in a consumer’s income level, income elasticity measures how they change their spending patterns among the different products they consume, including changes to their savings bucket. It measures how the changes in a consumer’s real income affect their demand for different products and services. How does income elasticity work?There are different outcomes when the income elasticity of the consumer is calculated. Demand can go up, stay the same, or even turn negative with the increase in the consumer’s income level. Similarly, when the consumer’s income level declines, the demand can turn negative, stay the same, or even turn positive with the change in the consumer’s income level. The income elasticity of the consumer is used to forecast demand for various products and services with changes in the business cycles. How is income elasticity of demand measured?Income elasticity of demand = percentage change in the quantity demanded of a particular product or a service (Δ Q) / Percentage change in the income level (Δ I). Income elasticity of demand can be 1, greater than 1 or lesser than 1. If the quantity demanded is Q, the original quantity demanded would be represented by Q 0, and the new quantity demanded after a change in the income will be Q1. Similarly, the original income level is represented by I0, and the changed income level is represented by I1. The formula for income elasticity can also be represented as ((Q1– Q0)/Q0)/ ((I1-I0)/I0). A calculated example of income elasticity of demand:
Examples of income elasticity of demand
Different types of income elasticityThe income elasticity of demand can vary according to the type of the good. Luxury goodsIf the income elasticity of demand for a good is greater than 1, then the particular good or service is said to be a luxury good. Whenever the income level rises, as is likely during the upturn of a business cycle or when the consumer shifts to another job with better pay and perquisites, their demand for luxury goods goes up. Examples of luxury goods include consumer durables, planning a holiday or a cruise abroad, luxury automobiles, jewellery and financial savings products in the form of top-ups and lump sum investments. As the consumer’s income level goes up, the demand for luxury goods increases. The opposite scenario occurs when there is a slump in the economy, and the consumer has to either take pay cuts or is out of a job. NecessitiesGoods for which the income elasticity is between zero and one are known as necessities. In the case of necessities, when the consumer’s income level goes up, they may consume slightly more, but the increase may not be significant. Necessities include standard grocery products that are consumed every day, like, water, electricity, food, and financial savings products. The goods belong to the industry sector known as defensives. Inferior GoodsInferior goods are those goods in which the income elasticity is less than 0. When the consumer’s income level goes up, the demand for these goods goes down proportionately. For example, a consumer who is consuming margarine or low priced cooking oils like Palmolein oil may switch to a pricier substitute product like butter or sunflower or olive oil. The demand for margarine or Palmolein oil is reduced more than proportionately. Graphical representation of income elasticity of demand for the different types of goods: The curved line in the above graph shows that the demand curve,
Interpretation of Income elasticity of demandInterpreting the income elasticity of demand helps classify a good as a luxury, a necessity or an inferior good. Income elasticity is an essential guide to consumer buying behaviour and consequently discerning the pattern of a firm’s investment in a particular industry. It helps analyse consumer budgets and their allocation of resources to various products and services consumed by them. Income elasticity is a vital tool in this context. Uses of income elasticity of demandStudying and analysing the income elasticity of demand is very important to businesses and firms. It enables them to predict the impact of income pattern changes on demand for products of different industry sectors. Products are classified as defensive, consumer discretionary and inferior products. All these products have differing income elasticities, which enable businesses to forecast customer buying patterns and analyse the underlying trends. They can study the correlations of business cycles trends with the demand forecasts of their products. When the business cycle is in the boom phase, incomes increase across the spectrum and vice versa during a slump. Predicting demand patterns based on this correlation between business cycles phases and income elasticity helps businesses plan for the future, prepare their yearly financial budgets and make growth and profit projections. Various applications of income elasticity of demand are given below: Benefits for a firm:
Benefits for a consumer:All human endeavour is undertaken to meet and satisfy our various wants and needs. Our wants and needs drive the demand for various products and services. Knowing our income elasticity helps us classify the products and services into different groups. It enables us to plan our budgets and undertake financial planning better. The underlying connection to trade cycles also helps us anticipate salary and income increases. We also understand better our buying behaviour, that it is based on sound economic principles and is not random or Adhoc. We can undertake better investment decisions when we analyse our income elasticity. Various factors that drive a consumer’s demand for a particular good or service are the fundamental building blocks of economics. Income elasticity of demand helps calculate the impact of change in income on the demand for a particular good or service. Thus, the importance of the concept of income elasticity of demand in the real world cannot be underestimated.

What does the income elasticity of demand measure?Income elasticity of demand is an economic measure of how responsive the quantity demanded for a good or service is to a change in income. The formula for calculating income elasticity of demand is the percentage change in quantity demanded divided by the percentage change in income.
When elasticity of demand is measured for a change in income it is called?The measure of responsiveness of the demand for a good towards the change in the price of a related good (substitutes and complements) is called cross price elasticity of demand. It is always measured in percentage terms.
What does income elasticity of demand measures quizlet?Income elasticity. In economics, income elasticity of demand measures the responsiveness of the demand for a good to a change in the income of the people demanding the good, ceteris paribus. It is calculated as the ratio of the percentage change in demand to the percentage change in income. You just studied 11 terms!
