Very interesting post on how the non-profit Feeding America implemented an auction system with its own currency which massively improved allocation of food to food banks.

How market design can feed the poor
America's largest non-profit had a broken distribution system. University of Chicago economists fixed it.

We also document changes in language about the randomization between the working paper and published version, and inconsistencies in the authors’ response. See full report (here osf.io/wp8fr/) for more details.

TIL the original paper describing CRISPR, by Francisco Mojica, was rejected by 4 journals and took 2 years to be published
CRISPR as a microbial immune system

In 2003, Mojica wrote the first paper suggesting that CRISPR was an innate microbial immune system. The paper was rejected by a series of high-profile journals, including Nature, Proceedings of the National Academy of Sciences, Molecular Microbiology and Nucleic Acids Research, before finally being accepted by Journal of Molecular Evolution in February, 2005.[3][4]

Why your covariates might be "lying" to you and other tales from the "identification frontier":
✅ CBPS-DiD for model misspecification
✅ When good controls go bad (CCC violations)
✅ Bayesian sensitivity for PT violations

Parallel Trends… Conditionally: Covariates, Violations, and More Robust DiD Methods
The devil in the ~DiD details~

Data come in many different formats and are used in many different ways, but in many cases, a checklist like this (along with good data documentation) can help you verify if a dataset is in a usable format for most general purposes.
