Kevin Drum weighs in on MMT at Mother Jones

Pretty good summary of the issue of full employment and price stability, contrasting the MMT fiscal position based on effective demand with the monetarist position based on NAIRU.

Who's Afraid of a Little Inflation?

(h/t Clonal in the comments)

Still no mention of sectoral balances and functional finance, the heart of MMT.

Drum does bring up and important point that is as under the radar as MMT. We need to be talking much more about the mainstream model's presumption of unlimited growth based on infinite resources in a world dominated by petroleum as the most important energy source.

POSTSCRIPT: Of course, you might also want to consider MPT, or Modern Petro-Monetary Theory. Rather than asking what level of economic growth kicks off unacceptable inflation, it asks what level of economic growth kicks off an oil price spike that produces a recession and higher unemployment. I have to admit that I increasingly think of the economy in those terms these days.

The only operational constraint according to MMT is not inflation, as it often expressed. Rather, it is availability of real resources. Inflation results when effective demand outpaces supply due to lack of availability of real resources, either through the inability of the economy to expand quickly enough to meet the increased demand (demand-side inflation) or because of lack of real resources (supply-side inflation).

Recent inflations in the developed world have resulted from shortage of petroleum relative to demand. This first occurred due to a monopoly by an oil cartel. While the Saudis are still the swing producers, the world seems to be running up against a natural supply constraint due to dwindling resources.

So far the discussion of MMT has been superficial. But at least it is being discussed.

UPDATE: Galbraith responds to Drum in Drum's comment section.

Kevin - your instinct on the oil price is on target, in my view.  The inflation threat that we face doesn't come from deficits or high employment -- it comes from the cost and price of energy.  But managing this is not within the competence of the Federal Reserve. 

I have been trying to call attention to this issue for years (it's in my 2008 book, The Predator State, and in articles written recently with Jing Chen, most recently in the Cambridge Journal of Economics, which contains the following paragraph:

"Our central argument is that stimulus fell short – and would havefallen short even if the amounts had been greater – becauseincreased demand under existing high-fixed cost structures drove, or would have driven, the price of resources too high, too quickly. The constraint on growth was not inflation generated by easy money, but the combination of the rising real marginal cost especially of energy, combined with monopoly control of and speculative instability in energy prices, which together act as a choke-chain on the return to full employment."

 But the endless debate over deficits, debt and quantitative easing tends to obscure this issue -- and in public discourse one cannot easily answer questions that are not being asked.  So thanks for making the point, and keep digging at it.
