Benefits of Resource Reallocation
1. Vertical integration
Net benefits = A
= total cost savings from substituting D2 – D1 of efficiency at Mcdemand
for S1-S2 of supply at Mcsupply

Benefits of Resource Reallocation
2. Wholesale competition
Net benefits = A + B + C
B = producer surplus lost to consumers from reduction in sales of S1 – S2 at MC1
C = producer surplus lost to consumers on sales of S2 at MC2 instead of at MC1

Benefits of Resource Reallocation
2. Wholesale competition (continued)
DRIPE = demand reduction induced price effect
= price suppression= C / (D2 – D1)
= (MC1 – MC2) S2 / (D2 – D1)
R = producer surplus from remaining sales of S2 at MC2
