Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 175. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 August 2026.
All research outputs
#290,528
of 34,365,356 outputs
Outputs from Quarterly Journal of Economics
#173
of 2,856 outputs
Outputs of similar age
#45
of 28,682 outputs
Outputs of similar age from Quarterly Journal of Economics
#2
of 11 outputs
Altmetric has tracked 34,365,356 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,856 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 50.2. This one has done particularly well, scoring higher than 93% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 28,682 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 11 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 81% of its contemporaries.
