The firm 1 chooses its output q1 to maximize its profits (All the firms do the same). Lerner Index is L=35.6%. It may come as a surprise that a drop in both the revenue and the volume-variable costs by $13,000 million, would raise the Postal Service Lerner Index (hence its market power) from 35.6% to 96%.
