Companies acquire or merge with each other for a variety of worthwhile reasons, ranging from managing uncertainty to gaining scale to accessing new resources. They also do it for less desirable reasons, including to gain market and political power, raise barriers to entry, or extract higher rents from consumers, workers, or suppliers. We must separate the good from the bad cases, and that is why most market economies require certain mergers to be vetted by antitrust authorities before they can be completed.
