BRIEFLY NOTED: For 2021-05-11 Tu

Snippet from a Dialogue:

Axiothea: The hole between the labor-force participation charge for prime-age employees and the unemployment charge remains to be massive—as massive because it was in 2014. That means to me that our first take needs to be that, apart from rate-of-change results, the labor market now could be about as tight because it was in 2014.

Kephalos: That the “labor scarcity” crowd thinks that the unemployment charge features a bunch of people who find themselves actually out-of-the-labor-force is one thing I discover considerably disturbing. Or do they not know that unemployment remains to be elevated?

Glaukon: The job-openings collection hit a rare file excessive on the finish of March: over 8 million. I counsel that helps reply among the questions. It definitely wouldn’t be simple to fill that many slots shortly, it doesn’t matter what degree of advantages persons are receiving (or certainly, how shortly employers increase wages).

That mentioned, I concern unemployment advantages obtain outsized consideration…. Monetary assist from tax rebates, ongoing pandemic fears, lack of entry to childcare and colleges, and retirements. Collectively, these elements level towards a reasonably sluggish restoration of the labor provide…. There’s additionally the elemental situation that firing occurs extra shortly than hiring…. A degree shift up in wages and costs doesn’t by itself equate to a change within the underlying dynamic that may perpetuate into persistently increased inflation. We most certainly is not going to have a lot sense of the persistence of inflation till the recognized base and reopening results go. Meaning the Fed is not going to need to validate any strikes by market contributors to drag charge hikes ahead once more on the idea of near-term inflation numbers…

I do suppose that fear about elevating taxes needs to be postponed till rates of interest have semi-normalized. However, in any other case, that is very sensible certainly:

Share Brad DeLong’s Greedy Actuality

Hoisted from the Archives:

Once I first noticed the Solow development mannequin in certainly one of my first economics courses, I raised my hand, and I requested: Why is it assumed that gross financial savings is a continuing share of gross earnings—that’s, earnings plus depreciation. Isn’t that the identical as assuming that persons are too silly to calculate deprecation? Shouldn’t the best assumption be that web financial savings is a continuing share of webearnings?

The instructor then filibustered.

I ultimately requested Bob Solow this query. He mentioned—precisely—that in his authentic paper it had certainly been web financial savings and web output (Cf. Solow (1956): A Contribution to the Concept of Financial Development <>, during which there isn’t any deprecation—the important thing parameters are “the financial savings charge, the capital-output ratio, the speed of enhance of the labor drive). When requested why he had shifted to gross financial savings as a relentless share of gross earnings, he shrugged his shoulders and mentioned ”referees”.


Except you assume that folks can’t calculate depreciation, the primary optimizing mannequin for a consultant agent one would naturally write down has web financial savings a share of web earnings, with the share relying on anticipated actual danger and return.

I’ve at all times taken it to be an indication of the low high quality of a lot of the criticism of Thomas Piketty’s Capital within the twenty first Century that professors declare Piketty’s assumption that web financial savings is a continuing share of web earnings is a gotcha—is (a) some type of an analytical mistake, as a result of it implies an ever-growing share of depreciation in gross output in a world the place the financial development charge of the economic system n+g = 0 is zero; and (b) that it’s a massively consequential mistake. IMHO, you may solely preserve it’s consequential should you lack familiarity with the NIPA, and its depreciation charges—if the “illustrative” deprecation charge you retain in 12 months head is 10% of income-earning wealth a 12 months, and so suppose that within the U.S. as we speak annual deprecation allowances are extra like $12 trillion/12 months (60% of GDP, 12% of the income-earning wealth inventory) than like $4 trillion/12 months (15% of GDP; 4% of the income-earning wealth inventory).

This, seven years in the past, actually didn’t go nicely in any respect.

You woulda thunk that folks wouldn’t double down after it was identified to them that (a) removed from being basic and canonical, depreciation was not even within the Solow (1956) that’s cited ten occasions a day, and (b) that one thing is badly improper along with your considering if the numbers you’ve in your head say that depreciation—capital consumption allowances—are 60% of U.S. GDP. However no! Removed from it!:

Per Krusell & Tony SmithIs Piketty’s “Second Legislation of Capitalism” Elementary?‘[Piketty’s] argument concerning the conduct of ok/y as development slows, in its disarming simplicity, doesn’t totally resonate with these of us who’ve studied primary development idea… or… optimizing development…. Did we miss one thing vital, even basic, that has been proper in entrance of us all alongside? These of you with customary fashionable coaching… have in all probability already seen the distinction between Piketty’s equation and the textbook model…. The capital-to-income ratio isn’t s/g however reasonably s/(g+δ), the place δ is the speed at which capital depreciates when development falls all the best way to zero, the denominator wouldn’t go to zero however as an alternative would go from, say 0.12—with g round 0.02 and δ=0.1 as cheap estimates—to 0.1…’

So as to not mislead, I’ve deleted the incorrect paragraphs that have been included within the first model of this publish…’

Brad DeLong: Brad DeLong [email protected] Wed, Jun 4, 2014, 2:34 PM: Please inform me if I’m loopy….

Piketty’s estimates of the capital/annual earnings ratio in France and Britain in 1910 are each equal to 7. At an annual depreciation charge of 10% and with a net-of-depreciation idea of earnings, that signifies that 41.176% of gross earnings is dedicated to changing worn-out capital.

That may’t be what anyone thinks, can it? For Piketty’s functions, a ten%/12 months charge of deprecation can’t be a good choice can it? Krusell and Smith’s alternative of a ten%/12 months depreciation charge to calibrate Piketty’s mannequin is senseless, does it?

Do folks actually suppose that in 1900 41.176% of French gross output was taken up by capital consumption?

Bodily capital depreciation charges in development (versus business-cycle) fashions are extra like 5% than 10%, aren’t they?

And to the prolong {that a} substantial chunk of your capital inventory takes the type of high-productivity land–which doesn’t depreciate–5% is simply too massive, isn’t it?

Am I loopy? 

Sincerely Yours,

Brad DeLong

Thomas Piketty: ’Hey, we do present future collection on capital depreciation in our “Capital is again” paper with Gabriel (see <>, appendix nation tables US.8, JP.8, and many others.). The collection are imperfect and incomplete, however they present that in just about each nation capital depreciation has risen from 5–8% of GDP within the nineteenth century and early twentieth century to 10–13% of GDP within the late twentieth and early twenty first centuries, i.e. from about 1% of capital inventory to about 2%… 



Pricey Professors Krusell, Smith, Hamilton:

This isn’t going nicely in any respect….

At Piketty’s reported wealth-to-annual-income ratio for France in 1910 of 700%, a ten%/12 months depreciation charge implies that capital consumption is 70% of web earnings—41% of gross output.

Thus I’ve seven questions:

  1. Do you consider that capital consumption was 70% of web earnings/41% of gross output in France in 1910?

  2. In the event you achieve this consider, how is such a remarkably excessive share–40% of all financial exercise in France dedicated to changing and repairing capital because it wears out and turns into out of date–in line with even a floor acquaintance of the construction of the French economic system in 1910? 

  3. In the event you achieve this consider, are you able to level me to any sources to again up such an enormous wedge between gross output and web earnings, particularly since Piketty and Zucman’s estimates of the wedge between gross output and web earnings are typically within the 5–8% vary for the nineteenth century and the ten–13% vary for as we speak?

  4. If not, why did you assume a deprecation charge that may result in such an absurd image of the construction of the French economic system as of 1910? 

  5. Have you considered what the suitable depreciation charge needs to be?

  6. How responsive do you consider the gross financial savings charge is to shifts within the wealth-to-annual-income ratio W/Y?

  7. How a lot belief do you’ve in life-cycle fashions of the impression of wealth on consumption in an surroundings of utmost inequality, like that of the Belle Époque, or (maybe) the mid–twenty first century?

Sincerely yours,

Brad DeLong

Per Krusell: ‘I actually didn’t admire the tone of your blogs on this matter. Due to the significance of the subject coated within the guide—it’s one I care tremendously about—and since so many individuals are enthusiastic about it, I nonetheless determined it made sense to put in writing a brief reply along with Tony. However, generally, on the few events after I write columns or visitor blogs, I’ve a rule not to answer individuals who don’t preserve a minimal of politeness of their questions/feedback. With out this rule, it might merely be too emotionally draining for me, and easily not value it. Because the tone of the e-mail you simply despatched remains to be reasonably disagreeable, with rhetorical questions and a transparent unwillingness to have interaction in our arguments, I’ll henceforth not reply…’

And so let me give the final phrase to Thomas Piketty:

Thomas Piketty: ’Thomas Piketty: ‘There are enormous variations throughout industries and throughout property, and depreciation charges might be rather a lot increased in some sectors. Identical factor for capital depth. The prolemb with taking away the housing sector (a very capital intensive sector) from mixture capital inventory is that when you begin to try this it’s not clear the place to cease (e.g. power is one other capital intensive sector). So we want to begin from an mixture macro perspective (together with housing), and right here it’s clear that 10% or 5% depreciation charges don’t make sense…’
