"The major reasons for diversification were by this time well established : to employ excess plant capacity, to eliminate seasonal humps, to guard against dependency on one industry, to enter new expanding industries, to supplement existing product lines, to use old products to create new product, and to secure a larger share of business in general."

“... did not set out to destroy the large corporation. Instead, each attempted to protect the legitimacy of the system by using existing law against the worst offenders or proposing new laws to change the rules of the system.”

“I use the metaphor "markets as politics" to create a sociological view of action in markets. I develop a conceptual view of the social institutions that comprise markets, discuss a sociological model of action in which market participants try to create stable worlds and find social solutions to competition, and discuss how markets and states are intimately linked. From these foundations, I generate propositions about how politics in markets work during various stages of market development-- formation, stability, and transformation. At the formation of markets, when actors in firms are trying to create a status hierarchy that enforces noncompetitive forms of competition, political action resembles social movements. In stable markets, incumbent firms defend their positions against challengers and invaders. During periods of market transformation, invaders can reintroduce more fluid social-movement-like conditions.”

“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 , 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.”

“The key argument is that managers and owners in firms search for stable patterns of interaction with their largest competitors. Once stable patterns prove to be both legal and profitable, firms set up organizational fields that tend to produce and reproduce those patterns.”

“I claim that the central goal of managers in the past hundred years has been to make sure their firms survived. To promote survival they proposed various forms of control, both inside and outside the firm. Internally, control was oriented to ensuring that organizational resources were deployed so that top management could be confident that their directives were being executed. Externally, this control was oriented toward establishing stable relations between competitors to promote the survival of their organizations.”

“The Celler-Kefauver Amendment to Section 7 of the Clayton Act has now been made effective by judicial ratification. The Supreme Court has said that the Act means exactly what it says... It prohibits acquisitions, either stock or assets, where competition in any line of commerce in any section of the country may be substantially lessened.”
