The fact that macroeconomics has gotten to the point that Robert Solow can be considered heterodox shows just how fucked-up things got.

The thing is that the Solow model makes absolutely excellent sense, and the only thing that marks it as a neoclassical model is the substitution of "saving" where "investment" should be. And it's always tested using the rate of investment anyway, because we have data on that, as opposed to the rate of saving which is quite difficult to measure precisely.

So yeah I think Solow is quite justified in thinking that of himself as a scientist in contrast to the quacks and charlatans infesting the profession.

Some of that is a difference in eras of economics.  Solow comes from an intellectual framework -- and sort of a period -- in which there was greater emphasis on getting good answers, as opposed to the political horseshit that has characterized economics for the last 40 years or so.

One could perhaps draw a distinction between Solow and Samuelson there.  Not that I blame Samuelson for people like Lucas and Prescott (Lucas and Prescott ultimately own it), but he played a role in laying the foundation for those types.

Well, Samuelson is on record admitting that he deliberately excluded whole ranges of policy space from his modeling, not because those policies were more difficult to model (though they are), or because they were practically infeasible. But because he thought that politicians, when given these policy options, would make "wrong" decisions (i.e. ones he did not agree with).

That, ultimately, is the fence in modern macroeconomics which distinguishes mullahs from scientists. And once you're on the wrong side of it, the difference down to von Mises and Greenspan is merely one of degree, not of kind.

Samuelson is also on record as describing how a Canadian Keynesian economist who published a well received textbook in 1946 subsequently was the victim of a coordinated conservative smear that linked him and his views to, gasp, SOCIALISM. The spectacle caused Samuelson to be very careful not to be vulnerable to such an attack. He did not say so but, likely, this effort to avoid attack by conservatives substantially drove him into their arms. Samuelson knew on which side his bread was buttered.

Solow is also undoubtedly angry with a lot of people due to the fact that much of Real Business Cycle theory is just the Solow model with some very stupid representative agents -- or brilliant, I suppose (since they live forever, take years-long vacations, and can anticipate everything perfectly) -- bolted on.  Anything they can't explain is the Solow Residual and hence business cycles are all about technology shocks.

Which Solow clearly thinks is completely idiotic.

Is 'the Solow Residual' a term of art amongst the RBC advocates?

The Solow residual is a term of art among a class of utility theoretic economic growth models. Technological progress is everything in productivity growth you can't account for after you have found all the factors correlated with productivity growth and have estimated their contribution.

Its an admission that utility theoretic growth modelling can't explain the most important long term factor in economic growth.

What Bruce said.  The term pre-dates RBC.  The Solow growth model has been around since the '50s, whereas RBC came around in the '80s.

RBC theorists just tend to be wedded to it.

Of course RBC assumptions about inherent limitations of the market to clear at certain times, about which nothing can be done, blows up if we take account of debt to GDP, as does Steve Keen, and take measures to deal with those implications in light of MMT and three sector national accounting.

RBC makes no assumptions about the inability of the market to clear.  Markets always clear in RBC models.  RBC models have instantaneous price adjustment, perfect competition, etc.

To get markets that don't clear, you have to add (usually nominal) rigidities and imperfect competition, at which point your model becomes New Keynesian rather than RBC.

(NK models perform a lot better at forecasting, but a lot better than "fucking terrible" is still not good.  Put it this way: Last I read, internal Federal Reserve forecasts were still putting both to shame.)

... easiest way to close an anticipatory model. That presumes that an anticipatory model that is a closed system accurately reflects the way that the economy works ...

... even though quite clearly it does not.
