Within the United States, rare earth research groups have been identified at the Bureau of Mines; Arizona State University; the University of Denver; the University of Dayton; Purdue University; and Penn State University. Internationally, research groups that studied rare earths included the University of Dundee, Great Britain; the University of Munich, Germany; the French National Center for Scientific Research; the Academy of Science of the USSR; the University of Genoa, Italy; Hebrew University in Israel; Tohoku University of Japan; and Helsinki University of Technology, Finland.

114. John D. Rockefeller vertically integrated Standard Oil during the last decades of the nineteenth century. After the Supreme Court ordered its dissolution in 1911, an oligarchy—Exxon, Mobil, Gulf, Texaco, Chevron, British Petroleum, and Royal Dutch Shell—dominated the drilling, refining, transporting, and selling of oil. Control over the different aspects of oil production gave the industry options and a degree of control when faced with global challenges. After World War II, new regimes emerged in the Middle East and they sought to nationalize their resources. Initially, “Big Oil” leveraged its technological know-how for continued access to Middle East oil by providing training to workers of the oil-rich countries. When “Big Oil” lost control of the oil reserves in the Middle East in the 1970s, it relied on its intellectual infrastructure, which it had sustained by its own volition and with the government’s support, to develop new technologies to identify and extract new reserves in the Gulf of Mexico and Alaska. Though faced with sustained opposition from environmental groups, public policy supported these efforts. See, for example, Pratt, Joseph A., “Exxon and the Control of Oil,” special issue, Journal of American History 99, no. 1 (June 2012): 148–50CrossRefGoogle Scholar; Painter, David S., “Oil and the American Century,” special issue, Journal of American History 99, no. 1 (June 2012): 37CrossRefGoogle Scholar; and Priest, Tyler, “The Dilemmas of Oil Empire,” special issue, Journal of American History 99, no. 1 (June 2012): 243–50.CrossRefGoogle Scholar

In contrast, the U.S. rare earth industry remained relatively diffuse during its lifetime. Molycorp’s operation concentrated on the mining and production of raw materials rather than extending its reach to encompass higher-level manufacturing. The expanded supply of rare earth stocks certainly stimulated and supported advancements in domestic rare earth technologies, but it left Molycorp itself vulnerable to the discovery of “the next lucrative source” of rare earths (just as the United States had grown dependent on India’s supply in the 1940s and China in the 2000s). One can argue that by vertically integrating, it might have had more options to pursue once China entered the picture. China has deliberately avoided such dependence inasmuch as it ultimately intended to use its own rare earth reserves to produce finished goods rather than sell raw materials to the international market. Though China first entered the industry as a supplier of raw materials, it leveraged its stock to bring in foreign corporations and know-how to jump-start its own vertical integration: mining, processing, and producing finished goods as well as developing a healthy intellectual infrastructure, all of which the government firmly backed.
