> I studied economics in Russia, and the term "dumping" was used in a more general sense as "selling goods or services below their cost"

Oooh! Do you have a recommendation for a translation of a Russian economics text? I’m particularly curious of Soviet-era texts that work on theory without prices.

> correct term for the US is "predatory pricing", and it's also prohibited by the Sherman Act

Sherman prohibits the “restraint of trade or commerce” [1]. The word “price” never appears in its text. In practice, predatory pricing is a tightly-regulated term that doesn’t generally prohibit selling goods below cost
