The tricky thing is what "same methodology, different data" means for economics. Replication is genuinely hard because the data sources are varied, and minimum wage applied in various settings could indeed have different effects. That wouldn't be a replication crisis, just an acknowledgment that effects are highly context dependent.
This chart is just replication attempts.
When people do attempt to replicate results in econ, they're more often able to do so than in other social sciences. That may actually be the reason there are fewer replication attempts: the juice isn't worth the squeeze.
Ah, thanks for digging into the actual paper and providing that context.
I just read the axes, maybe I'm actually wrong about what it means, and remembered other stuff I've seen on the Replication Crisis.
Thanks for reading the axes, which I clearly didn't! ~lol
Never asked myself that! (Then again, I'm into chess... Queen most powerful piece, King sort of a wimp... Made sense to me)
Can't speak to the underlying survey/methods here, but you could consider a study to replicate if it's directionally the same as others and/or theory, e.g., minimum wage laws always resulting in negative labor outcomes — instead of, as I recall the published literature here, a whole scatterplot flurry of effect sizes and signs.
