I've been meaning to go through the literature on every thrust and parry in the ongoing argument between proponents of a Job Guarantee and those of a Basic Income, and put together a thorough response. That's not going to happen in the next month or so, so in case I get hit by a bus, here's two paragraphs of where I stand (or don't stand) in the debate, lifted from a comment I just posted on Neil Wilson's blog:

Basic income vs. job guarantee is a false dichotomy that ill serves anybody who takes sides. There is undoubtably some overlap in that they both aim to reduce hardship and stimulate demand, but as far as I can see they’re mostly orthogonal in the range of problems they can potentially solve. Also they’re both programs that we already run, in the sense that we (in developed sovereign currency economies) already have a labour buffer stock program — unemployment — and a basic income, set at the level of zero.

I’m totally sold on (at least my understanding of) the job guarantee as a better implementation of a labour buffer stock, but I don’t think that “with a job guarantee in place, no matter what the particular circumstances may be, anywhere and forever, no level of basic income other than zero could be justifiable” is a defensible argument. And it runs counter to the general MMT stance of “these are the economic policy tools available; how you choose to use them is a political decision”.
