A firm’s Lerner index is given by L=(P-MC)/P and the firm’s marginal revenue, MR is related to its price elasticity E_d by the following formula: MR=P×(1+1/E_d ).
a. Using the firm’s profit-maximizing condition MR=MC, show that the Lerner index L is L=(-1)/E_d
b. What happens to the Lerner index when the demand become more elastic? Explain
