Explanation:

Dumping refers to the practice by firms of selling products abroad at below costs or significantly below prices in the home market. The former implies predatory pricing; the latter, price discrimination.
Dumping of both types is viewed by many governments as a form of international predation, the effect of which may be to disrupt the domestic market of foreign competitors. Economists argue, however, that price discriminatory dumping, where goods are not sold below their incremental costs of production, benefits consumers of the importing countries and harms only less efficient producers.
