As one of the problems of Fair Trade Laws are the a discount sale on on-line. Our country Fair Trade Laws should regulate what is called continuous predatory pricing and rival exclusion predatory pricing. But the United States, Great Britain and EU should demand a recoupment(supplement standard) in predatory pricing. The usual predatory pricing promotes competition and increases consumer profits. Probably, regulation of predatory pricing must limit and accept when the bargain sale company has the power of raising a price after eliminating a rival with predatory pricing.
The requirements for regulation on Fair Trade Laws in predatory pricing which is not clear. It is necessary to clarify to these. First, it is just going to accept chiefly which is less than an average variable cost as the fundamental figure of predatory pricing in the United States, Great Britain and EU. It is because a price setup which is less than an average variable cost can be considered only by trying to compensate the portion from which it suffered the damage after that after eliminating the rival by the event of market power. Second, although it exceeds the average variable cost, it is a price which is less than an average total cost. The United States has not done the problem such an act. But the intention of a doer is seen, and the illegality of an act is judged in Great Britain and EU.
It is necessary to set to analyze a price in network industry, and to reflect the economic reality nature of network industry. That is, the expense structure in network industry has common fixed expense very higher than the usual industry. And the variable cost in the case of providing electric communications service is low compared with the variable cost in the usual industry. Therefore, it will set to conduct expense analysis and it will be said that a suitable time structure's being required. And a time structure extremely called a short period or long period of time are not suitable.
