Foreign investment increasing in US minerals industry

Introduction Responding to Congressional inquiries regarding the purchase of a number of major domestic mining and metals companies by foreign firms, the US Bureau of Mines examined trends in foreign direct investment in the US. mining and mineral processing industries1. "Foreign Direct Investment in the US Minerals Industry" analyzes the extent of foreign investment in several major mineral commodity industries. It identified the countries of origin of foreign investment in US mineral assets. The study also described several reasons for the growth of foreign investment in US minerals and discussed some potential implications of this activity. Foreign investment trends in the economy and minerals For the economy as a whole, between 1977 and 1985 the number of US affiliates of foreign investors more than doubled - from 4046 to 9824 - as did employment at these affiliates - from 1.2 million workers to 2.9 million (Table 1)2. During this same time period, the total value of assets of all US affiliates throughout the economy rose from $239 billion to $736 billion (1985 constant dollars). In the domestic minerals industry, foreign investment also grew substantially during that same time as the number of US minerals-related affiliates increased by 74% - from 125 to 217 - between 1977 and 19853. During the same period, employment at all foreign-owned affiliate mineral operations in this country increased by 78% and totaled 198,000 workers at the end of 1985. Parallelling the growth in the number of and employment at foreign-owned US mineral and metal operations, the total value of US mineral assets owned by foreign firms (or individuals) has nearly doubled since 1977 and amounted to $30.9 billion at the end of 1985. The rate of increase in foreign investment in US mineral assets was slightly higher in the metals industries than in the nonmetallic groups. Foreign investment more prevalent in minerals Perhaps a more useful way of evaluating the growth in foreign investment is to analyze growth in the "intensity" of foreign investment - the proportion of total US industry assets held by foreign investors. Although insufficient data on total industry assets prevented the development of such a measure, employment data provide an indication of relative differences in the intensity of foreign investment among the mineral industries and other industries. For example, as noted in Fig. 1, the 198,000 minerals industry workers employed at US-affiliate companies in 1985 represented 12.7% of total employment in this sector of the economy. In comparison, for the mining and manufacturing sectors of the economy as a whole, 7.8% of all workers were employed at US-affiliate firms in 1985. For the total economy, 2.7% of the entire civilian employed workforce worked at US-affiliate firms that year. Using employment as an indicator, foreign investment has been more prevalent in the minerals industry than in most other industries. About one worker in eight in the minerals sector was employed at a US-affiliate firm in 1985. In comparison, for the goods producing sectors of the economy - all mining, petroleum, and manufacturing industries - about one worker in 13 was employed at a
