Dumping is tricky. I am actually sympathetic to the argument that says let them dump away. If China is subsidising cheap solar panels and manipulating their currency to make them even cheaper again, fine. Let's gorge ourselves on cheap solar panels. That's fine in theory, but the reality is more complex. What about long term investment in technology development? Control of strategic technologies? These apply to tech services too. I use Google Doc heavily, but I do worry that they are pricing out potentially innovative competition.
What if as consumer you benefit for a little while until all competition is dead - and then prices increase beyond prior levels? Will you still like “dumping” then?
A bigger worry for me is stagnation. Suppose Google Docs gets 'good enough' and prices out all the competition, but then Google loses interest because it's not exciting anymore.
This happened with Internet Explorer. We lost years of advancement in browser technology because they dominated, wiped out the competition but then lost interest. Yes competitors came along again after a few years, but there was a significant opportunity cost to all of us.
This is: https://en.wikipedia.org/wiki/Dumping_(pricing_policy)
"The objective of dumping is to increase market share in a foreign market by driving out competition and thereby create a monopoly situation where the exporter will be able to unilaterally dictate price and quality of the product".
Making cheap products from cheap materials (at a presumed profit) isn’t the same as loss-making pricing schemes even if the high level motivation to beat competitors is the same.
