I fell off Abbott with the new year, but let me catch back up.

My main q: how much of that upward trend is bc the avg author increases their number of coauthors? Maybe a shift-share decomp is a clearer ask to show over time if the avg increases bc shares move toward more coauthors or bc the avg author increases the number of coauthors between periods.

Could you measure the average change in number of authors for each new NBER working paper? Trying to understand difference between change in averages vs average of changes.

And here I thought those were one in the same

Y'all got a Link to the Past on there? 👀

BLS local area unemployment statistics go back to the 90s, but I would probably read the methodology because that is a very granular unit of obs to accurately measure population on an annual basis much less labor force participation.
