Income Elasticity of demand

The income elasticity measures the response rate of the amount due to an increase (or decrease) in income of consumers. The formula for the income elasticity (IEoD), is:

IEoD = (% change in the quantity required) / (% change on income)

To calculate the income elasticity

For example:

Given the following data, calculate the income elasticity of demand changes in the consumer income 40000 $ $ 50000th

The first thing we do find the data that we need. We know that income is $ 40000 and the new price is $ 50000 that we income (OLD) = $ 40000 and Income (NEW) = $ 50000. De la carte, we see that the amount requested if the income is $ 40000 and 150, if the price is $ 50000 is the 180th As we of $ 40000 to $ 50000, we have QDemand (OLD) = 150 and QDemand (NEW) = 180, where "QDemand" is an abbreviation of "quantity." Also, you should these four figures in written form:

The result (OLD) = 40,000

Income (NEW) = 50,000

QDemand (OLD) = 150
