Not speaking to any particular paper, because I’ve read plenty and I think economics is doing great stuff, but in general science suffers when methods precede question.
When we try to use the method in vogue we tailor questions to match it, often Limiting the social impact of our work.

It is bonkers to me that diff-in-diff is now more commonly discussed in research papers than instrumental variables.

Controversial take, apparently.
Maybe using the sky as a waste dump for our co2 pollution is not such a great idea.

In an absurd waste of time, I wrote a blog post about voting and the 19th Chopin Competition.
There has been controversy about who should have won.
Different voting systems would yield different winners. Differences in top rankings are statistically insignificant.

In this paper, we use the initial letter of each state as an instrument for educational outcomes, uncovering a strong negative treatment effect for the ‘M’ cohort.
Hard times for states starting with "M".

If I were running this experiment, I would also try to be a C-suite executive and run a company for a year.
Then I could make this comparison on solid footing.

it's not that i ever doubted that being a barista was a skilled position, but my year-long effort to try to produce a half-decent latte at home has convinced me that a good barista is easily more skilled than virtually every c-suite executive on the planet

I saw one squirrel chasing another squirrel and when it caught up the little rascal began to fly! I thought, is this a Superman-Lois Lane type situation?
Alas, the chasing squirrel was indeed a falcon.
Still exciting…except for Lois.

Two main points. 1. Musk's shenanigans hurt Tesla, but increased demand for other EVs, which is a good thing in the long term. 2. It has material implications for Net Zero policies in the short term.
