The evidence shows that WFH is more productive. There’s multiple papers on this topic at this point. Including one from the NBER as I recall.

The NBER study you linked seems to say that WFH saves workers 2 hours per week not that it increases their at-work productivity. It goes on to say that they claim to work more but it doesn’t say they actually get more done as a result.
> There will be a 5% productivity boost in the post-pandemic economy due to re-optimized working arrangements and less time spent commuting, NBER adds.
If this isn’t good enough do search yourself. There’s multiple papers and analyses by this point.
And these are all analyses to satisfy the all important business productivity goals of our corporations.
For humans, the actual workers? The saved time on commute, improved quality of life and invigoration of local markets far outweigh those corporate gains.
