In your country, the demand curve of a litre of petrol is given by: P = 107 - 5QD. Due to political unrest coupled with the slow recovery from pandemic, the global price of petrol surged which led to an increase of price per litre of petrol in your country from TK55 to TK80. After the price rise, the employees of the company you work for demanded a pay-raise. Your employer, hence, increased your income from 31033 taka to 46187 taka. The new demand curve at the new income level is P = 132 - 5QD. A). Calculate the income elasticity of demand (YED). B) Now assume that the increase in income (and the subsequent shift of the demand curve) had occured before the rise in price, then what would the YED be?
