The farther afield mergers were, the less likely antitrust authorities were to intervene. Growth through mergers required that finance-oriented manag… - Neil Fligstein

The finance conception of the modern corporation, which currently dominates, emphasizes control through the use of financial tools which measure performance according to profit rates. Product lines are evaluated on their short-run profitability and important management decisions are based on the potential profitability of each line. Firms are viewed as collections of assets earning differing rates of return, not as producers of given goods. The firm is not seen as being a member of only one industry. Consequently if the prospect of an industry in which it participates declines, the firm disinvests. The problem for management from this perspective is to maximize short-run rates of return by altering product mix, thereby increasing shareholder equity and keeping the stock price high

Property rights, governance structures and rules of exchange are arenas in which modern states establish rules for economic actors. States provide stable and reliable conditions under which firms organize, compete, cooperate and exchange. The enforcement of the laws affects what conceptions of control can produce stable markets. There are political contests over the content of laws, their applicability to given firms and markets, and the extent and direction of state intervention into economy. Such laws are never neutral. They favor certain groups of firms.

The purpose of the large horizontal (same-product) mergers was to reduce the number of plants and, hence, control production enough to insure a reasonable rate of profit. Mergers would allow a newly created large firm to produce full-time in its most efficient plants, and thereby maintain prices, production, and profits.
