What isn’t transitory is the tight labor market. Long-term demographics show that we’re going to be in a labor shortage for 20 years. Fed policy, economic models, etc. won’t solve this. The high-tech sector may be at an inflection point but it will be the high-tech sector (AI, automation, high-end manufacturing) must take up the slack in the labor market. The age-participation numbers are already set in motion. Unless we significantly increase immigration (politically infeasible with a gridlocked, coin-operated Congress), the burden/challenge falls to high tech.

During the whole section about "how long it takes" I was rolling my eyes and whining "come ON! What about the Doh and Foerster paper!"

... And then you mentioned it lol

In general I think everyone (academics, laypeople, pundits) underestimate how often systems lack any kind of "long run average". We crave a kind of certainty and predictability in the world that often just isn't there.

Great overview and analysis, thanks

Seems like inflation has fallen back to 3-4 pct. Fed wants it back at 2-3 pct. My guess is we don’t see the Fed cutting until we get several months in a row of 2 pct handle core numbers (ex housing, food, energy) and unemployment is back above 4 pct. If we get a surprise recession we could see cuts without a return to 2 pct core inflation, I suppose, but Fed won’t like that.

Love this.

Here is the Big Idea for you, mentioned it before

It appears from what I see and how you describe various economists, that everyone only thinks and uses "linear elastic" modeling. But almost all the phenomena discussed has a "time component". Springs, elastic push-react and pull react is leaving out viscous time constants.

https://en.m.wikipedia.org/wiki/Viscoelasticity

Look at all these types of curves from stress relaxation, creep, etc

There is another methodology to consider in macroeconomic modeling. We test polymers with....not impulse but....cyclic testing.

We're not interested here, in prediction. We are interested in characterization. We want to see the phase angle, ie time.delay between an input and the output.

I can't get you farther here with my agednans degrades skills. But I believe that there are a lot of various important relationships that have different time constants as well as linear response.

I apologize for this embarrassingly newbie question, but how does home affordability factor into economic measurements? I ask because a common sentiment I experience talking to day-to-day people is that the economy is awful / inflation is awful because homes are less affordable now than ever.

Great article and analysis of all the perspectives. I think the various lags are being seen in goods but services (wages) will take much longer. The Fed’s sufficiently restrictive level will be very interesting given the core and stickier inflation areas.

Already the DXY is cratering and loosening financial conditions and that isn’t what the Fed wants as it makes inflation harder to fight. Example: US import prices have increased again.

I enjoyed the Wile E. Coyote reference so looked it up. Krugman used it in 2007 in the context of dollar mis-pricing: https://archive.nytimes.com/krugman.blogs.nytimes.com/2007/09/20/is-this-the-wile-e-coyote-moment/

Re the importance of expectations:

Doesn't it follow from the popularity of predictions based on the yield curve, which is inherently driven by expectations, that expectations are important? I think, based on my own PhD research (also with input from Miles Kimball, btw), that expectation formation itself has a lag because of information lags and measurement noise. Lags in expectation formation are shorter than the 2-3 years you mention -- more like the six-month range. Also, lags are not the same as pure delays -- they are smooth, so the other guy's position that "...there’s no way that inflation could be falling because of the Fed’s rate hikes, because rate hikes take over a year to have an effect" sounds wrong to me.

Re the Fed's policy:

By my reckoning, the Fed was a year late in raising rates. Had they been on time, they would not have needed to be so aggressive. As they dilly-dallied, I worried that they would not be aggressive enough when they finally got around to it. I was happy my worries in that regard turned out to be unfounded. And for what it's worth, I think they are correct to still be raising rates slowly, but it won't be long until they need to level off and then lower rates (I predict fairly aggressively) to catch inflation at or near target. By delaying for so long, the Fed got itself into a situation in which aggressive moves and precise timing are needed to pull off a win. That said, it seems to me they are doing just that.

This is timely and extremely elucidating. Thanks, Noah. I'm going to make sure Drum sees this (though he probably has already).

Typo in the paragraph after the “median cpi” graph. “where you don’t nearly as much worry about inflation anymore.”

They've already over-corrected, since inflation is below 4 per cent, which is the sensible target. If there is a recession, it will be associated with a further decline in inflation, to the point where the zero low bound on the funds rate will be hit yet again, and more QE is needed. Supposedly, this will enhance the credibility of the Fed

Science seems to progress by continually taking in new observations and creating new, more complex theories to account for anomalous observations using newly forged tools. Newton invented calculus for his physics. Newtonian physics was replaced by relativity and quantum mechanics, which used previously unused mathematical tools. The relative simplicity of Darwin's evolution has been replaced by more complex models based on previously unused biochemistry and biophysics. Economics in this decade has been complicated by the effects of a pandemic and a shooting war between developed nation-states with relatively evenly matched mechanized weapon systems. I'm no economist, but this post suggests that economics is ready for a new toolbox..

Worth noting that the average white collar worker's belief in a coming recession is likely driven largely by the salience of layoffs from prominent companies. Of course, you're right to be reading data instead of extrapolating the vibes on LinkedIn, but to your point, inflation and recessions are both self-fulfilling prophecies, and the vibes on LinkedIn *are* likely affecting the consumption decisions of a group that consumes a lot.

So much of the discussion of how inflation is discussed in commentary is very different from what I learned doing my economics major. I was taught that interest rates fight inflation by vacuuming money out of the economy. Interest rates raise because the fed sells bonds like crazy through open market operations. This both lowers the price of bonds (raises interest rates) and hoovers up dollars. Fewer dollars in the economy raises the value of dollars relative to goods and services, which means dollar denominated prices go down (inflation goes down). Is that wrong? Does this just not happen, or is the effect too small to be worth mentioning? I think talking through this either to explain why is wrong or why it's right would be a great subject for a blog post. Or maybe someone can just explain it to me here...

There's one big reason that inflation is falling, and will continue to fall - the M2 money supply is DECLINING. M2 previously hadn't seen a YoY fall in at least 60+ years.

It was the MoM falls in M2 that gave me the confidence many months ago to call June as the peak in CPI growth & for drastically lower inflation ahead.

Given the extent of the deceleration in M2, the reverse of what happened post the COVID stimulus is playing out now (e.g. cratering durables prices, falling spot market rents, plunging freight rates and lower oil & gasoline prices).

In my 2023 outlook I forecast CPI ex-shelter to not only fall below 2%, but also a significant likelihood of outright YoY DEFLATION by June (my full report is available for free on my Substack).

The Fed continuing to tighten in the face of falling M2 risks a SEVERE recession. There's absolutely NO need for additional tightening, which only risks MORE inflation, not less. Why? Because plunging the economy into a severe recession risks a repeat of the TRILLIONS in stimulus that caused the current bout of high inflation. This is what risks a 70s style yo-yoing of inflation, not pulling back on what is ALREADY the most aggressive tightening campaign in over 40 years.

You are taking Havranek & Rusnak WAY out of context. They use *both* hump-shaped and increasing responses to central bank policy in their estimate, and their results vary by country, with the US having a best estimate of 42 months - 3 and a half years.

By the source you have cited, the Fed has drastically over-reacted to the inflation rate, and an implication is we're likely to get a long a painful recession.
