MAC^A = 16 - E and MAC^B = 16 - E. The firms are being regulated to E^SE as the overall level of emissions produced.

MAC^A = 16 - E and MAC^B = 16 - E. The firms are being regulated to E^SE as the overall level of emissions produced. What is the difference between the least and most efficient distribution of emissions across the two firms? MD = 4 + E / 2. Please draw necessary graphs and show all calculations.
