When the price elasticity of demand is greater than one, the good is considered to demonstrate elastic demand. The larger the price elasticity of demand, the more responsive quantity demanded is given a change in price. It is common to simply drop the negative of the quotient. The law of demand states that an increase in price reduces the quantity demanded, and it is why demand curves are downwards sloping unless the good is a Giffen good. It is computed as the percentage change in quantity demanded over the percentage change in price, and it will commonly result in a negative elasticity because of the law of demand. Price elasticity of demand demonstrates how a change in price affects the quantity demanded. If income elasticity is negative, the good is inferior. If income elasticity is positive, the good is normal.The four factors that affect price elasticity of demand are (1) availability of substitutes, (2) if the good is a luxury or a necessity, (3) the proportion of income spent on the good, and (4) how much time has elapsed since the time the price changed.The three major forms of elasticity are price elasticity of demand, cross-price elasticity of demand, and income elasticity of demand.Elasticity is a general measure of the responsiveness of an economic variable in response to a change in another economic variable.Thus YED has an important effect on resource allocation within an economy and the speed and nature of sectoral change as countries develop. Rather, it is often the case that these goods are imported from other countries, often newly industrialised countries, which may be able to produce the manufactured goods with a comparative advantage, i.e. This is not because people in rich countries fail to buy more manufactured goods as they become better off. In the more developed countries, the tendency is for the tertiary sector to grow the most rapidly in response to rising real incomes. Hence the secondary and tertiary sectors grow much more rapidly than the primary sector as living standards rise. As we become better off, there tends to be a more than proportionate increase in demand for electrical equipment, furniture, banking, travel and tourism etc. The demand for manufactured goods and the services of the tertiary sector, however, tend to have a very high YED. Consequently, the primary sector is likely to grow only slowly as living standards rise. No matter how rich you are, there is a limit to how much fruit and vegetables you can eat, so an increase in income may not stimulate a large increase in consumption of these goods. as real incomes rise, there tends to be a less than proportionate rise in demand for these products. fruit, vegetables, raw materials and so on tend to have a low YED i.e. In general, the products of the primary sector e.g. Fundamentally, this is because of the importance if YED. Typically, as economic growth occurs and real incomes and living standards rise over time, the primary sector tends to become relatively less important, while the secondary and tertiary sectors tend to become relatively more important. Can you write down the FORMULA? Follow the link to check your answer.Įconomic growth is the increase in productive capacity of the economy and is best measured by the increase in real GDP (output) over a period of time. Income elasticity of demand (YED) is the responsiveness of demand to changes in income.
