Suppose your demand schedule for e-books is the following:
Price |
Quantity demanded (income = € 15,000) |
Quantity demanded (income = € 22,000) |
€ 10 |
48 |
55 |
€ 12 |
40 |
50 |
€ 14 |
32 |
45 |
€ 16 |
24 |
40 |
€ 18 |
16 |
35 |
Calculate your price elasticity of demand as the price of e-books increases from €10 to €12 if (i) your income is €15,000, and (ii) your income is €22,000. Is it elastic, inelastic or unit elastic?
i. Calculation of price elasticoty of demand :
Price increase from $10 to $12
Price elasticity of demand = Proportionate change in quantity demanded/ Proportionate change in price
= ((Change in Quantity/ Quantity)*100)/((Change in price/ Price)*100)
=((40-48)/48)*100/ ((12-10)/10)*100= -0.83
Since, elasticity is less than 1 so it is inelastic.
When income is 15000,
Price elasticity of demand=
((50-55)/50)*100/ ((12-10)/10)*100= 0.45
It is also relatively more inelastic.
