Now with everything reopened there are many more options.
Productivity almost always goes up in a recession, especially one accompanied with massive layoffs (like early COVID).
Productivity is going down right now compared to 2020 because we are pretty much at full employment.
These productivity measurements aren’t really tracking individual productivity at all.
So the measurement during periods of recession or expansion will always be artificially elevated or suppressed.
Their chart shows we are far below any sort of pre-pandemic baseline.
So that graph does not say we've dropped below pre-pandemic levels.... according to this report (https://www.bls.gov/news.release/prod2.nr0.htm): "Output and hours worked in the nonfarm business sector are now 3.1 percent and 1.5 percent above their fourth-quarter 2019 levels, respectively."
The chart is showing "annual percentage change in labor output", not "gross productivity" which I think supports the OPs point.
If it went up 10% in 2020, and 6.3% in 2021 (or whatever the graph is showing), just because there is a -7.4% drop in 2022 doesn't mean its "far below any pre-pandemic baseline".
In fact it's probably ABOVE pre-pandemic levels, even with the drop. I can't be certain from graph.
Musical instruments from the 30’s are legendary.
The simplest explanation is probably just that the workers who were laid off during Covid were the least productive, and so average worker output went up, then fell as they re-entered the labor force. Or maybe even just there was some sort of abberation with how the complex statistic or productivity was calculated (e.g. inflation was actually here earlier than measured by CPI, and output was deflated incorrectly).
Either way, this is much more likely a pandemic related disruption and return to normalcy, rather than an indication that anything fundamental is "broken"
