1. (i) Demand function for tickets for a rock concert has been estimated to be

ln Q = 3.737 - 1.518 ln P +1.213 ln I

where Q denotes number of tickets (in thousands), P the (average) ticket price and I the average income of the concert goers.

Determine the values of the price elasticity of demand and the income elasticity of demand.
