As, I've said several times, I'm perfectly able to distinguish between Trump's character as an individual and the rationale for his policies. I don't quite understand why you keep repeating that or why you seem wedded to that interpretation?
What I keep saying over and over, is that there has been no clear, sensible, comprehensive (or comprehensible) explanation of the theory or the calculations behind this, other than that he does not seem to understand either tariffs or trade deficits.
I understand the flaws in Ricardian Trade Theory in the modern world, but I'm not really sure about your reading comprehension. The BBC article does not provide a rationale. It's a pretty straightforward, not particularly deep look at various issues around what's happening, mostly with a negative slant on Trump's actions. It does conclude with with what's below. I'm curious as to in what universe 'Perhaps there is some substance to the theory that the real objective here is to weaken the dollar and lower US borrowing costs. For now, the US is checking out of the global trade system it created. It can continue without it. But the transition is going to be very messy indeed.' provides what I asked for, which is a reputable economist espousing this as a viable and/or likely strategy.
From the BBC article:
In the game theory of trade wars, credibility does matter. The US has unrivalled military and technological might, which helps. But to transform the global trading system using an arbitrary formula, that throws up transparent absurdities, even without the penguins, is likely to encourage the other side to resist.
This is especially the case when the rest of the world thinks that the loaded gun that the president is holding is being aimed at his own foot. The stock market fell most in the US. Inflation will go up most in the US. It is Wall Street now calculating a more-than-evens chance of a recession in the US.
Perhaps there is some substance to the theory that the real objective here is to weaken the dollar and lower US borrowing costs.
For now, the US is checking out of the global trade system it created. It can continue without it. But the transition is going to be very messy indeed.
