New work with @edkong and Mark Shepard: jamanetwork.com/journals/jama-…
ARPA made zero-premium silver plans available to folks < 150% FPL. But only two at the most: the second-lowest (benchmark) and lowest-cost plans on the tier
Is *which* two plans are lowest-cost—$0—stable over time?

How widespread a concern is non-independence in studies of national-level outcomes? We reviewed the 100 highest-cited cross-national studies in economics and psychology. Our review showed that attempts to control for non-independence are rare, and have not increased since 1993.

1/ Can A.I. do our literature reviews for us? Stop everything and try elicit.org, an amazing new tool that uses large language models to answer research questions via empirical research- in the video below I ask it "Does social media negatively impact mental health?"
^didn’t work for my lit but YMMV
Interesting discussions

Three years into my PhD program, I think I've finally figured out a paper reading system that works well for me.
There are 4 main steps in my workflow: finding papers, storing papers, reading papers, and annotating papers.
A brief 🧵 on my what I use:

#EconTwitter: what are the most costly mistakes you've made in running a RCT in the field (so we can all collectively avoid them)? I'll start (actually 2, but from the same project): launching the baseline without implementers having made non-reversible inv in the program.
^somewhat related: “highest impact RCTs of all time?”
