And some utterly damning charts.
1) at *every* point on the income distribution, Americans live shorter lives than the English.
I picked the solution for 17 because that one looked particularly funny to me, but it's not just this number with an awkward looking solution - the arrangements for most numbers are asymmetrical, the neat ones like 16 are the exception.

Here is a very simple python implementation of Doubly-Robust DID, by Sant'Anna and Zhao. It helped me understand the paper, but also showed me how to view DID through the lens of delta outcomes. Hope someone else finds it useful.

In math, there are lists of "open problems" -- i.e. Qs that the field thinks are important but no one knows the answer to.
Do we have open problems in econometrics?
Or is the issue that we don't know what Qs we should be asking?

I also recommend using methods that actually recover LATE (or LATT) when covariates are needed. Our (@TymonSloczynski@sderyauysal) DR LATE (LATT) estimators are easy to compute and doubly robust. Let Doctor LATE cure your identification ills. π¬

Hi #EconTwitter!
This paper by @cblandhol (@Princeton), @theJohnBonney (@Stanford), Mogstad and Torgovitsky (@UChi_Economics) shows that 2SLS estimates of LATE ππ«ππππ¦ππ§π πππππππ¬ could be invalid if the specification includes covariates.
Highly recommended!
