Subsidy and protectionism are economic weapon.
It takes time to build up an infrastructure for an industry, killing your competitors with subsidy then raise the price up after all your competitors are gone. Robber baron and standard oil have done it in the past, it is now being done on country level.
Do you know of any modern of current examples of a country or a corporation doing this?
Solar companies in China seem to be doing this. And since Chinese YUAN is being subsidized by average China citizen, one can also argue all the producers/exporters in China are doing it to kill their competitors abroad.
What are they doing exactly? Producing solar panels below cost in order to push out competition? How does a stronger Yuan help them in this regard? I thought that a weaker currency benefitted exporters?
I have heard some things about the Chinese solar industry, but I'm not exactly clear on what the situation is.
