Why Regulate Mergers?


Thomas Edison commenting on the creation of General Electric Company in 1892

'Recently there has been sharp rivalry between [Thomson-Houston and Edison General Electric], and prices have been cut so that there has been little profit in the manufacture of electrical machinery for anybody. The consolidation of the companies....will do away with a competition which has become so sharp that the product of the factories has been worth little more than ordinary hardware.' New York Times, 21.2.1892. Cited in Scherer and Ross (1990).

The Competition Test

CA Definition of SLC

'The SLC test is interpreted in terms of consumer welfare. Consumer welfare depends on a range of variables including price, output, quality, variety and innovation. In most cases, the effect on consumer welfare is measured by whether the price in the market will rise. The conclusion that an SLC will result from a merger is thus based on whether the price to buyers is expected to rise (or output to fall). Where price is not the appropriate variable, welfare is measured by the changes in the relevant variables.'
