A Non-Sokratic Monologue on D. Carleton Gajdusek and Some Conclusions on the Incommensurability of Moral Aggregation
Originally from a Twitter thread with Mike Bevel, most of which was captured by Threadreaderapp here: https://threadreaderapp.com/thread/1396104609891028996.html.
From Brad DeLong's substack, originally a Twitter thread started by Claudia Sahm, in which I have a vivid recollection from a 2008 University of Chicago conference where John Cochrane made a keynote speech:
This is your new edition of Grasping Reality—The SubStack Newsletter, by Brad DeLong:
A Non-Socratic Dialogue on the Decline of Milton Friedman's Influence; & BRIEFLY NOTED: For 2021-05-22 Sa
Things that went whizzing by that I want to remember...
A Non-Socratic Dialogue:
Milton Friedman’s Influence Kept Right-Wing Economists from Reverting to Full Crazed Liquidationist Nutjobs for 60 Years. But Why Did It Then Decline So Fast in the Decade of the 2000s?
Claudia Sahm: "We should have a recession,” John H. Cochrane said in November , speaking to students and investors. “People who spend their lives pounding nails in Nevada need something else to do.” #yikes <https://t.co/vbSKhIRMtR> by @delong <https://braddelong.substack.com/p/reading-john-lippert-on-the-idiocy>
Scott Gosnell: I was there. I may even have a recording down in the archives and may have sprained my eyes I rolled them so hard.
Brad DeLong: What! Really? Tell me more…
I mean, private housing construction as a share of GDP had crashed from its peak of 5.0% of GDP in 2005Q4 through its historical average of 3.4% in 2007Q2, and had bottomed all the way down to 2.1% by 2008Q4, when Cochrane was opining about too many people pounding nails in Nevada:
How was it possible to say such a thing? How could he avoid looking at graphs like this one, and noticing that residential construction employment had already fallen from 150% to 60% of its normal share even as he spoke?
And how did the audience react?
Joe Marshall: Holy hell. What the f—- was wrong with these people?
Scott Gosnell: I went to all of those econ talks at Gleacher while I lived in Chicago. The noticeable thing about Cochrane was that he was very good at financial economics, but fell apart when he tried to jump to macro. But of course faculty could say all kinds of things without getting much skepticism. Being a Mellon-style liquidationist was sort of edgy and cool among the Republican-leaning economists at the time.
Brad DeLong: Touché... One question I always ask Paul Krugman and company is: what happened to the influence of Milton Friedman? No one was a stronger anti-liquidationist than Milton Friedman.… The shift to "liquidationism" as the default policy view of a Republican economist (when Republicans were out of power, at least), seems to have happened remarkably quickly in one decade, the 2000s, and without analysis and without argument. How and why did this happen, that being a full-fledged Mellonian became "edgy" and "cool"?
Scott Gosnell: I think it came swift on the heels of a Randian political moment. Where before, Austrian economics would get you a glance askance, in 2008, it would get you a $300+ bottle of wine at dinner with Paul Ryan.
Brad DeLong: Touché... The Hayek-Hoover-Mellon-Marx axis was a remarkable thing among Republican economists... especially since nobody has ever been able to write down a coherent overinvestment business-cycle model...
Paul Krugman: Hey, I answered that question at length some years back <https://t.co/MCuyiMwXCg>: Friedman tried to save free-market economics from itself, admitting that the economy wasn’t self-correcting but arguing that a rule that didn’t sound Keynesian would let conservative avoid thinking about that…. But ultimately free-market Keynesian, even disguised with a monetarist mask, wasn’t sustainable.
Jim Beller: Having his disciples throwing people out of airplanes was a bad look.
Brad DeLong: But, Paul, as you note, Bernanke in 2002 and Mankiw in 2006 still saw Friedman as “the economist of the century” <https://gregmankiw.blogspot.com/2006/11/milton-friedman.html> <https://federalreserve.gov/BOARDDOCS/SPEECHES/2002/20021108/>. They were fine with the “government should not interfere with the economy” and “whatever is the monetary policy that happens to stabilize aggregate demand is the true non-interfering ‘neutral’ monetary policy”. It was a con, yes, but it was a successful con. And it is not clear that it was wrong as a practical policy position…. JM Keynes (macro)-Henry Simons (antitrust)-AC Pigou (externalities) is not that far from what you or I believe, or what Milton Friedman believed—or, at least, would graciously concede in his old age in outdoor lunch in North Beach if I could get him off of his hobbyhorses of ‘k% rule’ & ‘government failure is almost always certain to be worse than market failure.’
The way you put it in your 2013 piece is like this:
If markets can go so wrong that they cause Great Depressions, how can you be a free-market true believer on everything except macro? And as American conservatism moved ever further right, it had no room for any kind of interventionism, not even the sterilized, clean-room interventionism of Friedman’s monetarism”.
I think that is (a) right, (b) much too compressed, but (c) ignores the problem of “where do you stop?”
Having the government establish & maintain a property-rights order & enforce contracts is, after all, a form of “interference” to the anarcho-capitalists. And while there are some ACs who want a contract dispute between you and me resolved by me “hiring” my police force and you “hiring” ours and the two settling the dispute by the Final Argument of Kings—thus going all the way back to full feudalism as society’s organizing principle—most do not. Most stop being happy with police & courts.
So why is police & courts acceptable, while police & courts & demand management is not?
I think it has something to do with Schumpeter, von Hayek, and von Mises; the context of early–20th center Vienna; the idea that humans are individuals for whom private property and one-shot exchange are “natural” (as opposed to creatures that establish and cement societal bonds via ongoing reciprocal gift-exchange relationships); the philosophical position that all is for the best in this the best of all possible worlds; and the resulting theological belief that:
the market giveth; the market taketh away; blessed be the name of the market…
In short, I think you are right, but I do not understand why you are right.
And here I know I am out of my depth, and I want to call for people like Emma Rothschild and Glory Liu who are trained professionals to help here, for they she might be able to teacheth me the lesson…

Very Briefly Noted:
Jiwon Choi, Ilyana Kuziemko, Ebonya Washington, & Gavin Wright: Local Economic and Political Effects of Trade Deals: Evidence from NAFT: ‘Counties whose 1990 employment depended on industries vulnerable to Mexican import competition via the 1994 North American Free Trade Agreement (NAFTA) suffer large employment losses (relative to the bottom quartile of counties, counties in the top quartile of NAFTA exposure see 5–8 log-point declines in employ- ment by 2000). Despite large employment losses, we can reject even modest population declines. Trade-adjustment-aid relief rises, but covers a tiny share of the job losses we document, and Disability Insurance in fact displays a much larger response. Exposed counties (many in the upper South) begin the period more Democratic in terms of votes in House elections, but as NAFTA is debated in 1992–1994 they shift in the Republican direction and by 2000 vote majority-Republican in House elections. We show with a variety of microdata, including 1992–1994 respondent-level panel data, that opposition to free trade predicts shifts towards Republican party identification…
Matthew Yglesias: Seventeen Points on Israel & Palestine : ‘As Joe Biden says, America is an idea…. not an ethnostate…. The worst moments in our history trace specifically to the politics of ethnic exclusion…. This is the greatest country on earth…. The best country Jewish people have ever had in history…. The current iteration of the Zionist project appeals mostly to believers in ethnic nationalism. Ethnic nationalism is, as they say, Bad For The Jews…. I am a Jewish American who likes his cosmopolitan liberalism, thank you very much. I find it incredibly regrettable that hard nationalism is on the rise globally, and think that it is leading to pain and misery that will only get worse if it continues to gain steam…. The Israel-Palestine situation has its own unique features, but it is also part of a fairly general trend toward hardening sovereignty claims and deploying nationalism to mask official corruption…
Dan Nexon: Against Great Power Competition: ‘Biden underscored his intention to “work with Beijing when it’s in America’s interests to do so,” but days later noted the likelihood of “extreme competition” with China…. [Moreover,] Republicans are certain to criticize the administration for being weak and ineffective in the face of international challenges…. This is unfortunate. For all the concept’s influence in recent years, great-power competition is not a coherent framework for U.S. foreign policy…. Rivalries between leading states exist in every international system…. With Washington’s unipolar status now on the wane, powers such as China and Russia find it easier than they once did to challenge U.S. leadership…. It is one thing, though, for Washington to observe increasing competition among great powers and adjust to a world in which it enjoys less influence than it once did. It is another entirely to elevate competition itself to the guiding paradigm of U.S. foreign policy—as the Trump administration proposed and Biden may wind up doing…. When adopted as a foundational paradigm of foreign relations, great-power competition relegates collaboration to an afterthought or, worse, dismisses it as naive…
