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.

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

Conceptions of control refer to understandings that structure perceptions of how a market works and that allow actors to interpret their world and act to control situations. A conception of control is simultaneously a worldview that allows actors to interpret the actions of others and a reflection of how the market is structured. Conceptions of control reflect market-specific agreements between actors in firms on principles of internal organization (i.e., forms of hierarchy), tactics for competition or cooperation, and the hierarchy or status ordering of firms in a given market. The state must ratify, help to create, or at the very least, not oppose a conception of control.
