A good peer reviewer - who engages thoughtfully and constructively, teaches, notes what's good about a paper and what can be improved - is such a positive force. As a mentor (and as an editor and an author), I send out deep thanks to everyone who works hard to write kind and useful reviews.

I think this question was probably the starting point of Dube, Lester, and Reich's (2010) “local estimators comparing all contiguous counties” approach...! At the very least, spatial heterogeneity would be less concerning than simply including state FE.

We use transfer learning, a machine learning approach that addresses the deviation-variance tradeoff.

It combines large source data with small target data to create a dementia estimation algorithm.

I read an interesting paper on the limits of causal inference methods for questions where there is no counterfactual for the broad structural exposures of interest (e.g., impact of systemic racism on health)

Very brief commentary by Vanessa Didelez on causal discovery and the role of expert knowledge when building DAGs: academic.oup.com/aje/advance-...
Already suspected that I would like this after her talk yesterday, but I really do dig her writing -- it's very crisp and accessible.

Invited Commentary: Where Do the Causal DAGs Come From?

Abstract
How do we construct our causal DAGs, e.g. for life course modelling and analysis? In this commentary I review how the data-driven construction of causal DAGs (causal discovery) has evolved, what promises it holds and what limitations or caveats must be considered. In conclusion I find that expert- or theory-driven model building might benefit from some more checking against the data and causal discovery could bring new ideas into old theories.

Here is our response to a recent critique of our 2018 paper on police killings+mental health.

The critique had obvious problems, but nevertheless instigated a formal investigation (which we passed). This was stressful. I am posting because our reply could be useful for teaching:
