Antitrust

A common reason for antitrust investigation is with mergers and acquisitions. The Department of Justice must approve proposed mergers, to ensure that the merger or acquisition activity does not unduly restrain competition in an industry or market.

The concern was that post-merger, the combined entity would be able to constrain competition and by virtue of that raise prices, in a market whose customers depend on access to those low prices (Heneghan, 2015).

Antitrust behavior comes with it costs to the economy. The underlying principle of antitrust legislation is that when there is insufficient competition in a market, the participants in that market have the ability to exploit that lack of competition, and raise their prices to a level that would not occur if the market was competitive (Investopedia, 2015).

If one of these bought another, there would only be two, and the larger would have a significant majority share of the market. As a result, the industry would be an oligopoly and lack sufficient competition.

That said, there are different ways to define an industry. If the industry is defined as dollar stores, the proposed acquisition would not go through, because it would create oligopoly conditions. If the industry is defined as general retail, there are many other players in this industry. The market shares of these dollars stores would be insignificant in a business with….....
