Traditionally, antitrust laws have been concerned with competition and concentration within a single market. In the past few years, however, increasing attention has been given to economywide or aggregate concentration-especially when such concentration is accomplished by merger rather than by internal growth. In 1979 and 1980, Congress considered Senate Bill S. 600 which would limit mergers based on size criteria that are unrelated, at least directly, to proof of a lessening of competition within any given market. The international implications of applying this principle are complex and difficult, and have yet to be fully addressed. It is the purpose of this article to articulate the contours of this area of emerging importance.
