Defining what does and does not constitute predatory behavior is difficult to define clearly and concisely.
One potential mitigation, given the above, would be to routinely break up companies above a certain size. To make it perfectly typical, ordinary, and automatic to do so. To shift the burden of proof from the government needing to establish monopoly status to the giant company needing to demonstrate that the consumer benefits due to economies of scale derived from its size outweigh the negative externalities due to its size and subsequent disproportionate power and influence.
Economies of scale leading to lower consumer prices are a positive good. The negative externalities of huge companies due to their size and outsized power and influence aren't given as much consideration as they are less quantifiable, but they are real and should be taken into account.
Framing the law would be tricky though, as one doesn't want to criminalise high-growth (read: VC-funded) startups.
Taking this ability away without being careful means you'll likely further entrench incumbents at the expense of those new companies.
For example a company like Uber should not be allowed to sell rides for less than what they pay the driver for the ride.
These kinds of laws are fundamentally political in nature, as there is no real 'neutral' ground.
Dumping, in the context of international trade, is very specifically a price discrimination rather than just an absolute price concept: it's where you export for cheaper than you sell domestically.
I know that there is lots of theory on this, but has any company really ever gotten to this point?
Trade wars between nations happen all the time because of dumping. Timber, aluminum, soybeans, and all kinds of other commodities.
Tech companies have largely gotten a pass on normal business practices and codes of conduct this century because they're shiny and new. But as the industry ages, it will have to learn to work within the boundaries or ordinary civilization.
Seems like something that would be really easy to take advantage of by buying the material sold cheap and selling it later at a profit.
The one I can find most recently is: https://www.bloomberg.com/news/articles/2021-06-24/china-sue...
> China filed a lawsuit at the World Trade Organization over Australian anti-dumping and anti-subsidy measures on Chinese exports of railway wheels, wind towers and stainless steel sinks, the Ministry of Commerce said Thursday in Beijing. This would be the third recent WTO case between the two countries, after Australia sued over Chinese tariffs on wine and barley.
Prior to that (three weeks ago), it was China dumping steel alleged by Japan.
In section 3.1.4 of the annex, they go into some detail regarding a dumping claim on electric bicycles from China.
