This bit really struck me: “Matthew Rognlie—then a doctoral student, now an assistant professor at Northwestern—took up that line in even greater detail in an article that eventually appeared in the Brookings Papers on Economic Activity, to which he added that the rising capital-to-income ratio in Piketty’s data is disproportionately the result of the price appreciation of certain scarce stores of wealth, primarily h…

I have some problems with that same quote. The "disproportionate price appreciation of housing and the land it sits on" seems to me to be primarily a factor only in some (maybe most) large cities; outside those cities, price appreciation, perhaps excessive price appreciation, has occurred, but it's nothing like that in those few cities. My feeling is that, sure, the effect of real estate prices are large in real terms, but compared to the rest of the economy, they are limited in effect by their limited distribution. (I haven't looked at Rognlie's research; I could be wrong.)

Further, my feeling is that real estate appreciation is an effect, not a cause. Consider the 2008 event ("circumstance?" "shenanigan?"): it was purely driven by the financial industry. It had, really, nothing to do with real estate at its core; it was caused by bad financial behavior, and the failure of the real estate market was simply how it was translated out of the finance world into the rest of the economy.

Likewise, my impression of the situation you describe is a result of the growth and success of the financial industry and the pursuit of a very limited class of real estate assets by that resulting block of money.

Tl;dr: High rents in San Francisco? Caused by the venture capital industry---a purely financial operation---and its insistence on having all of its investments physically co-located with where it wants to live.

Tom Woods has a series of good critiques of Piketty. Here’s one: https://tomwoods.com/ep-318-piketty-taken-down-for-good/

I'm seeing a lot of signals on that site that throw up red flags and honestly the content is confirming those assumptions. I find this talk radio guy and his guest Phil Magness of George Mason to be the ideologically blinkered ones as I follow their arguments and cross-reference them with what was written in Capital.

You mean like the pop-up ad for his book and newsletter?

"Three Words That Say "I'm Clueless"

""Deregulation caused it!"

"We've all heard that account of the financial crisis.

"It's dead wrong. Preposterously wrong.

"It's all the Left has.

"Don't let them get away with it.

"Solution: enter your email address below for your free copy of The Deregulation Bogeyman and to start receiving the legendary Tom Woods Letter."

I picked up his book and in 45 seconds figured out he was wrong...by looking at the index.

He has an entire collection of stats and measurements, but, no where in the index is the gold standard mentioned.

Changing from a silver and/or gold based monetary standard to a fully-fiat model as almost every government did at some point in the first half of the 20th century, should have resulted in various adjustments; adjustments that he should have mentioned and discussed.

(Heck, even changing from the Deutsch Mark to the Euro resulted in price changes for Germans.)

If he did discuss it but they made a lousy index, then, please give me page numbers in his book and I promise to re-examine...

Because, "It is difficult to get a man to understand something, when his salary depends upon his not understanding it!". Economists' careers as receivers of grants, policy advisors, members of prestigious think tanks and organizations, and pundits, depends on being good at promoting whatever aligns with the elite's interests.

Unless all the startup funding in the valley is going to pitch decks about real estate I don't see how your tldr follows.

But then you have to ask yourself why this surge in demand for real estate in urban areas hasn't been met by a corresponding surge in supply? Why aren't developers building new apartment complexes as fast as they can to cash in?

The answer is primary that regulation by local governments prevents them from doing that thereby keeping real estate prices high.

"In the book, Piketty relies on a paper by Loukas Karabarbounis and Brent Neiman that estimated a high marginal elasticity of substitution given two sets of facts: capital has gained national income at the expense of labor, and the price of capital inputs to production has been falling. The authors interpret the latter as the cause of the former, and again within the confines of neoclassical production theory, the only way to reconcile those two facts is with a high degree of factor substitutability: when capital becomes cheap, firms switch to using it, displacing workers. The labor displacement exceeds the increase in wages to workers who remain employed, thus reducing the total labor share of national income. That paper does not mention Piketty, but in a follow-up the next year, the same authors foreground the similar model proposed by Piketty."

Back in the '80s and '90s, a topic that I kept seeing was, "where is the productivity?" With companies spending huge money on technology and computerization, there should have been visible gains in productivity numbers, right? But, there weren't. What's up with that?

My thoughts, as a non-economist, when I saw that were of things like just-in-time inventory controls, which were new and entirely dependent on new technology. They needed massive structural changes, which may be why they didn't show up immediately, but still...they were there and the metrics and models of economists weren't capturing their effects until they had completely taken over.

Likewise, the elasticity of labor and capitol sounds very much like the effects of automation on industrial jobs.

"The aforementioned paper by Furman and Orszag argues that what Piketty (and Gabriel Zucman, in their joint work) identify as a high and invariant rate of return on capital in aggregate in fact reflects uncompetitively high rate of return on capital for a few specific, superstar firms in the economy, and the key task is not to manipulate aggregate macro equations, as Piketty (and neoclassical economists more generally) do, but rather to explain why these superstar firms do so much better than everyone else. The short version, according to Furman and Orszag, is rents—payments that some agents, superstar firms in this case, are able to extract from the rest of the economy either because they have successfully blocked any competitive pressure or because they have bought special treatment through the political system, or some combination of the two, in addition to other mechanisms."

Or perhaps we're talking about things like the FAANG set. the extracted payments are personal information---which is not captured in any economic theory I've ever seen---and the moat blocking competitive pressure is the combined result of network effects (bigger databases win) and extensive financial capitalization. (How do you fight a competitor to whom not only is additional capital effectively free but also has huge stocks of monetary capital just lying around in stacks on the floor?)

This paragraph seems bothersome: "Most striking, however, is that when you hold educational attainment and other observable worker characteristics constant, pay is starkly different depending on the firm where you work, even within narrowly-defined education categories, industries and occupations. This is prima-facie evidence that the human capital model in a competitive labor market is an increasingly poor way to ex…

Yes, that paragraph is very, very bad, because it's not people of equal education that would have equal wages, but equal productivity---which will vary depending on what firm you're at! Not just because of sorting and poaching of talent, but some firms' production and capital structure will be such that the marginal worker will be more productive.

This comment manages to mix some elitist contempt of the arts with a whiff of conspiracy theory, while not saying anything of substance about Piketty’s work. Well done!
