with explanations of the how to calculate income elasticity of de. The microeconomics concept of yed or income elasticity of demand is explored in this video. yed measures how much the demand for a product or service changes if there is a change in real income. demand is not only affected by price (ped) but also by consumer income (yed). Income elasticity of demand (yed) measures how responsive demand is to a change in income and hence, is another useful tool for making marketing decisions. the yed = 4 10 = 0.4 definition of luxury good. The yed = 15 10 = 1.5 definition of normal good this occurs when an increase in income leads to an increase in demand for the good, therefore yed >0 for example, if demand for apples rose 4% after a 10% rise in income.

If income were to rise, bicycle sales would begin to fall.

Example: Bicycle transportation is an inferior good, because Americans demanded MORE bicycles as their incomes fell.

This is a good that people will buy more of as income falls, and less of as income rises. An inferior good is one with a negative YED coefficient. Cars are a normal good, so the YED coefficient is positive. If incomes were to rise, car sales would begin to rise.

Example: As incomes fell, car sales fell as well.

There is a direct relationship between income and demand.

>1: Elastic – Demand for the good is relatively responsive to changes in income (quantity will change by a larger percentage than consumers’ income) YED can be either positive or negative A normal good i s one with a positive YED coefficient.

1: Unit Elastic – Demand for the good is proportionally responsive to income changes (quantity will change by the same percentage as the change in income).

0-1: Inelastic – Demand for the good is relatively unresponsive to changes in consumer income (quantity will change by a smaller percentage than the change in income).

Car sales have fallen by 3% YED for bikes = 8 ÷ -4= -2 Demand for bikes is income elastic YED for cars = -3 ÷ -4 = 0.75 64Į Demand for cars is income inelastic As with PED and XED, the absolute value of YED can be:.

YED= Percentage change in the quantity of a good ÷ Percentage change in consumer’s income, or ED Y = %∆Y %∆Qd Assume the following: YED is a measure of how responsive consumers’ demand for bicycles and cars is to changes in their incomes. Demand for new cars is falling, but demand for bicycles is rising. For example, imagine a country is going into recession, so the income of the average household is falling. Income elasticity of demand (YED) measures the responsiveness of consumers of a good to a change in the level of their income.

Examine the implications for producers and for the economy of a relatively low YED for primary products, a relatively higher YED for manufactured products and an even higher YED for services.

Distinguish, with reference to YED, between necessity (income inelastic) goods and luxury (income elastic) goods.

Show that normal goods have a positive value of YED and inferior goods have a negative value of YED.
