After a protracted interval the place the US labor market outperformed even a number of the extra optimistic predictions, the July 2024 numbers got here in under expectations with weaker employment progress and the unemployment charge rising to 4.3%. Whereas from a historic perspective 4.3% stays low and never removed from estimates of the equilibrium charge of unemployment, the truth that unemployment has now elevated for a number of months, has began a dialog about whether or not these figures can sign the start of a recession.
A few of this dialog is motivated by an indicator proposed by economist Claudia Sahm and named after her because the Sahm rule. This indicator was initially created to establish recessions in actual time in order that it might be utilized by coverage makers to set off supporting insurance policies. The indicator seems at how unemployment compares with latest ranges. Traditionally, a rise of 0.5% relative to baseline is a robust indicator of the start of a recession. Within the post-WWII interval this indicator has produced two false positives though in each circumstances a recession adopted quickly after (see Sahm (2024) for an in depth description of the indicator).
Whereas the indicator was not designed to foretell recessions, its robust correlation with recessionary dynamics has been sufficient to set off hypothesis about whether or not a recession is imminent, very a lot within the spirit of what occurs when the yield curve inverts. Statistical regularities that preceded earlier recessions won’t have a lot energy to foretell the following recession as a result of the variety of enterprise cycles is small and, as well as, every of them might be totally different in nature. Even when a sure indicator has all the time preceded all earlier recessions, “this time might be totally different”. To this point the labor market restoration from the 2020 recession has certainly been very totally different from any of the earlier recoveries however as we glance ahead we face the query of whether or not it might probably proceed doing so.
The US labor market throughout expansions
The Sahm rule is said to a set of broader patterns of the US labor market which might be shared by all cycles within the post-WWII interval. Exterior of recessions, the US labor market is sort of all the time in a state of therapeutic, with the unemployment charge reducing after a recession. Other than these lengthy and uninterrupted episodes of therapeutic, we solely observe very quick durations of secure (and low) unemployment. Throughout these durations unemployment strikes sideways with some tendency to slowly creep up, till the Sahm rule is triggered, and the episode is interrupted by the following recession (see Determine 1).
To additional perceive this sample, we take a detailed take a look at the newest 4 US enterprise cycles. We give attention to the restoration interval, outlined to start out the month after the height of unemployment, which all the time occurs just a few months after the trough outlined by the NBER. We then depend the variety of uninterrupted months the place the unemployment charge was on a downward pattern, we are going to seek advice from this era because the “therapeutic interval”. We outline a downward pattern as a damaging change within the 3-month shifting common of the distinction between month-to-month unemployment and the common unemployment charge in the course of the earlier 12 months (this metric is near the one used within the Sahm rule). This therapeutic part is all the time adopted by an episode of secure or rising unemployment, though at a really small charge in some circumstances, till the following recession begins. We seek advice from this part because the “pre-recession” interval. These latter episodes are very quick relative to the therapeutic interval. Desk 1 summarizes how the info splits between these two phases throughout every of the final 4 recessions.

The desk above highlights a number of essential and associated information:
1. In all 4 cycles many of the restoration is spent within the uninterrupted therapeutic part. The everyday habits of unemployment outdoors of a recession is reducing.
2. The pace of adjustment in the course of the therapeutic part is low in order that it takes a few years to return to a low unemployment charge. In comparison with most labor market fashions, the pace of adjustment tends to be too low and too secure over time. Most theories predict that the pace of adjustment ought to be a lot quicker within the early components of the restoration. This helps theories of congestion within the labor market. (Corridor and Kudlyak (2021), Mercan, Schoefer, and Sedláček (2024)).
3. Full employment doesn’t appear to be a pure state of the labor market. As a substitute, the labor market appears to nearly all the time be therapeutic from a recession (Fatas (2021a)). The episodes of secure and low unemployment are very quick. In truth, throughout the vast majority of what we name the “pre-recession” part, unemployment is trending upwards. As soon as unemployment reaches the tip of its therapeutic interval, a recession follows quickly.
4. The US labor market doesn’t show any slowdown durations or “mini-recessions”, the place small shocks push the unemployment charge up by a small quantity earlier than returning to equilibrium. The dynamics of unemployment are dominated by the very lengthy technique of uninterrupted therapeutic from giant and rare shocks (recessions).
Will we observe the identical patterns in different international locations? Not as robust because the US. The US labor market is exclusive as a result of the patterns described above are prevalent throughout all cycles. In different international locations we additionally see dynamics that aren’t current within the US.
For instance, in France, the enlargement of the early Nineteen Nineties began with the standard therapeutic interval however as soon as unemployment reached low ranges within the early 2000s, it remained broadly secure till the 2008 recessions alternating durations of accelerating and reducing unemployment (this determine makes use of AFSE (2024) recession dates for France).
Within the UK we see the same sample throughout the identical many years with unemployment remaining secure for a interval of 8 years within the early 2000s with some fluctuations in each instructions (for UK recession dates we use Broadberry et al (2023) and ONS (2022)).
These episodes that we observe in France and the UK the place the labor market spends a number of years with out a clear pattern and small fluctuations in each instructions are absent within the US labor market. That is the rationale why the statistical remark that drives the Sahm rule works nicely within the US. When unemployment isn’t reducing, it’s seemingly {that a} recession is across the nook, and a brief interval of even the smallest enhance sends a fair stronger sign {that a} recession is imminent.
This time is totally different. For a way lengthy?
The final cycle within the US labor market is exclusive on many counts. From Desk 1, we will see that the therapeutic interval was very quick in comparison with the opposite cycles, extra so if we think about the excessive degree of unemployment from which it began. The pace of adjustment in the direction of a low unemployment charge was a lot quicker than in some other enlargement.
However what’s extra related to grasp at this time’s labor market is that the interval of low and secure unemployment has already been for much longer than something now we have seen within the earlier cycles. The US labor market has already spent 13 months after the therapeutic interval ended and this represents about one third of the enlargement time. This sample may be very totally different from earlier cycles.
One may argue that the US economic system has achieved, from a labor market perspective, a really profitable and long-lasting delicate touchdown. However now the query is about how lengthy the US labor market can keep in that state. Earlier cycles present a pessimistic reply to that query as these durations all the time tended to be quick in nature. However like with some other empirical regularity, such because the yield curve inversion, utilizing patterns of unemployment to foretell the following recession ignores the likelihood that this cycle could be totally different.
From a theoretical perspective, we should not have a lot steerage. Why did earlier durations of low unemployment finish quickly? One risk is solely {that a} very lengthy therapeutic interval mixed with the inevitability of some giant shocks alongside the best way make it not possible to see lengthy episodes of full employment (Fatas(2021b)). However, as soon as once more, we have to think about that this time “was totally different”. The therapeutic interval was a lot shorter and, consequently, whereas the post-healing interval is longer than in different cycles, the size of the enlargement isn’t. That enables for an optimistic studying even when one sticks to empirical regularities as there could be room for extra years of a decent labor market whereas we look forward to the following shock that sends the US economic system right into a recession. And as now we have proven, now we have noticed these patterns in different international locations of secure and even weakening at instances labor marketplace for just a few years with out a recession.
