The income elasticity of demand is computed as:
“E_Y = dfrac{%Delta Q}{%Delta Y}”
The percentage change in demand is:
“%Delta Q = dfrac{90 – 100}{100} times 100 = -10%”
If the income decreases by 20%, the income elasticity of demand is equal to:
“E_Y = dfrac{-10%}{-20%}”
“boxed{color{red}{E_Y = 0.5}}”
