New Bruce Hansen paper argues that DD papers should estimate standard errors using jackknife instead of clustering, which "can be highly biased towards zero"
From @theathletic.bsky.social: Josh Allen, currently the best NFL player on the planet, made a month’s worth of 'Are you kidding me?' plays on Sunday, leaving his Bills teammates in awe. "He's mythical." nyti.ms/3VGboni
Impressive! And this is why testing for cluster correlation in error terms can't be the right way to decide on the level of clustering. At least not in a design-based approach. Unobserved heterogeneity in the distribution of the treatment, or in the TEs, gets mistaken for "cluster correlation."
In order to add some clarity on why the answer is just "use robust SE", here's a simulations that follow Abadie et al.'s paper "When Should You Adjust Standard Errors for Clustering?"
This is pure random assignment of treatment. Cluster SE are way too big, and robust SE are close.
Congratulations!!
Josh being Josh🔥 this run was awesome #Bills

Great to chat with Nick and Goldy on Pitchfork Economics podcast about economics’ socioeconomic diversity problem
I strongly believe that this means we miss important perspectives and get things wrong in our research.
But I’m hoping to test this in data - Watch this space….
