Paul Romer on Paul Volcker
By David Henderson
Economist Paul Romer reprints a letter he received from an aspiring graduate student in economics and his response to the reader. There is much that is valuable in the letter. In fact, it’s on net valuable.
But I will follow Paul’s advice he gives in one part of his response to challenge what he says in another part.
Here’s the advice I will follow:
When you consider graduate school or a job offer, try find one that has a culture like the one that Milton Friedman described at the University of Chicago when he said “an academic is concerned not with being diplomatic, not with trying to avoid hurting people’s feelings, but an academic is concerned with saying what’s right. Telling the truth, or trying to get at it. And if you disagree with somebody you don’t say ‘well, now there may be something in what you say’ … You say ‘that’s a bunch of nonsense.'”
Now to the part I want to challenge. Paul writes:
To learn about a department, visit and ask macroeconomists you meet “honestly, what do you think was the cause of the recessions of 1980 and 1982.” If they say anything other than “Paul Volcker caused them [the two recessions] to bring inflation down,” treat this as at least a yellow caution flag.
That’s nonsense. Paul Romer makes it sound as if recessions per se bring inflation down. If you think that’s true, ask yourself this: What if the federal government causes a recession by cartelizing all industries, which causes those industries to raise prices? Then you get recession plus inflation. What’s in fact true, and what, I hope, Paul Romer meant, is that Paul Volcker used a drop in the growth rate of the money supply to bring inflation down and that the virtually inevitable result was two recessions.
