MS-131 Double Marginalization v05

[Market Simulation] MS-131 Double Marginalization
Market Simulation (MS-131) - Double Marginalization - Part 1Illustrates how a supply chain of Wholesaler to Retailer to Consumer will beinefficient and add unnecessary economic deadweight loss. The DoubleMarginalization problem is resolved if the Wholesaler and the Retailer merge.The loop jumps between the Wholesaler and the Retailer. Each sets theirProfit Maximizing Price based upon the demand they see. The loop continuesuntil an equilibrium is found. From Wikipedia:https://en.wikipedia.org/wiki/Mergers_and_acquisitionsA common example of such an externality is double marginalization. Doublemarginalization occurs when both the upstream and downstream firms havemonopoly power and each firm reduces output from the competitive level to themonopoly level, creating two deadweight losses. After a merger, the verticallyintegrated firm can collect one deadweight loss by setting the downstream firm'soutput to the competitive level. This increases profits and consumer surplus. Amerger that creates a vertically integrated firm can be profitable.
