MMTはかなり受け入れられつつある、と。

 

この記事を日本のMMT派が「WSJがMMTを認めた！」と喜んでいるのは笑える。"MMT isn’t the future. It’s here now"というのは「財政バラマキは（MMT以外の普通の経済理論では）正当化できないが、すでに現実だ」というpayfors（財政タカ派）に対する皮肉だよ。 https://t.co/5gNsloNHEJ

The government hasn’t embraced MMT. But important elements of it are now accepted by much of the economic and financial establishment, with major implications for how the economy is run.

 The most important claim of MMT is that a government need never default on debt issued in its own currency. The lesson of 2020 was that MMT is right.

Central banks that had struggled for a decade to boost inflation using monetary tools found that fiscal tools were far more powerful. Government spending does far more for inflation than quantitative easing, it turns out, and central-bank calls for more fiscal action to boost the economy are more likely to be accepted next time deflation looms.

Key parts of MMT haven’t been adopted, particularly its call for government to guarantee everyone a job.

In the next downturn it is going to be very difficult for governments to resist calls to provide huge support, now that it has been shown that bond markets don’t care.

MMT is both right and wildly optimistic that higher taxes could slow an overheated economy and bring down inflation. The flip side of last year’s demonstration of the power of fiscal policy is that higher taxes can suck demand out of the economy much more effectively than the Fed’s interest-rate tools.

素人でわからんが、記事をぱっと読む限りかなり受け入れられつつあるんじゃないの？
