A rare economic prediction (and probably wrong): inflation is not government-spending induced or opening-and-closing-of-the-economy induced, and hence transitory; but climate-change induced, and so not merely transitory.
In a larger sense, I’d argue that both the pandemic and climate change fall under the category of being consequences to our devastation of the environment — and that that devastation is increasing prices, finally — carbon tax or no — so there will be inflation.
(Maybe: in the absence of a carbon tax or cap, there must be inflation?) (Don’t know anything about economics of course — but I wonder– what is the relationship between inflation and so-called “exterior costs”? Exterior costs must be paid for somehow and one of those ways might be destruction of property and another of those ways might be inflation, which I guess is similar if not the same.)
