No, UBI only works if you institute price controls, or if there is a mass migration to rural areas, Otherwise, it just sparks an inflationary spiral. The spiral is even quicker if UBI is 'adjusted' for regional cost of living.
There is good reason to think that a tax-supported UBI at any level would, in fact, lead to price inflation for goods disproportionately in demand at the low end of the income scale, such that the net benefit of a UBI to the lowest-income recipients would be less than would be expected by consideration of the nominal benefit and pre-policy price levels, sure.
The idea that it would just spark an inflationary spiral, OTOH, something that needs some support.
Fair point. My assumption is that any political movement that institutes UBI in the first place would add automatic indexing to CPI either in the initial bill or soon after the first inflationary surge. Even if (miraculously) resisted at the federal level, the pressure to automatically index in urban areas would be overwhelming and even a few major cities with local indexing laws would still spark the inflationary spiral.
I'm gonna go with "maybe" - there are a whole lot of details there and there may well be good plans in that space.
I'd like to get back to this when I have a bit more bandwidth.
Price control? Is this some sort of a joke?
