    Episode 12: What's our causal effect called?

    In one sense, causal inference has two approaches. You can run a regression and then backwards engineer what it means. Think of Imbens and Angrist's 1994 classic Econometrica on the local average treatment effect (LATE) where they show that the Wald estimator (binary treatment, binary instrument) is the average effect for the complier subpopulation. But the other way that causal inference often runs is you start with the parameter of interest, not the regression, and then build the regressions to identify them under minimal but acceptable assumptions. In this episode of the Odd Couple, we switch from estimation to description of the causal parameters introduced in Callaway, Goodman-Bacon and Sant'Anna (2026, AER). These are the well known ATT parameter, but not the ACRT, which is the slope of the dose response curve. We also puzzle over whether our treatment is, in fact, distance measured in levels or is it distance measured as changes. Which is probably one of the values of starting with parameters: it forces you to figure out what your question is! Scott's Mixtape Substack is a reader-supported publication.

    Episode 11: Why is our number this number?

    Welcome to the 11th episode of The Mixtape with Scott, season 5, “The Odd Couple” featuring Caitlin Myers! This week we continue the riveting material from last week where we walked through a decomposition of the twoway fixed effects estimator when it’s 2 period, diff-in-diff with a continuous treatment! Yes, you heard me right — be still my beating heart. Scott's Mixtape Substack is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber. Me and Caitlin continue to go through this deck that Claude made for us explaining the new Callaway, Goodman-Bacon and Sant’Anna paper, forthcoming at AER, about continuous treatment diff-in-diff. Mainly, though, we are just working our way painstakingly slow through this Frisch-Waugh-Lovell decomposition of the OLS regression to better understand just what OLS is doing. I thought this episode was pretty interesting though your mileage may vary. I mean, if you don’t find two economists trying to help each other understand an econometrics paper, then probably the floor on this episode could be a little low. But that said, I did enjoy it. We both really seemed to help one another better understand the decomposition formula, plus we got to see it with our own eyes. And Claude made some really intuitive graphics that helped both of us.

    Episode 10: Doses and Decompositions!

    Today will astonish and amaze because in this one, you will watch me explain the decomposition of the OLS twoway fixed effects estimator for the continuous treatment difference-in-differences! A first for podcast history I would be willing to bet! Thanks again for turning in! (Caitlin said she thought this turned out well, but your mileage may vary).

    Episode 9: Mystery Solved!

    This week's episode of "The Odd Couple" is just Caitlin and Hannah as I had to go to Georgetown to talk about Claude Code at a faculty retreat. But before we get going with a description, Hannah mentioned at the start during the ice breaker about the opening theme song to the podcast, and for those that don't recognize the lyrics, that's Mac Miller's "Small Worlds" sung by my two nephews. So what is this episode about? One of the themes I have been emphasizing in my talks on AI Agents and my substack is that AI Agents have caused a separation between the historic bundling of the production of research and the verification of the results. Since AI Agents are now able to produce so many aspects of the research project autonomously -- that is without much direction from the human researcher -- one of the new tasks of the researcher is to verify them. If you remember from a few weeks ago, Claude Code had nearly instantly worked up the county-level marriage data into a county panel of marriage rates and marriage counts by year. We brought Hannah Sayre, a recent college graduate and current economic consultant, into the project to help us work through the latter task of "human verification". Had Claude done it correctly? How do we verify that it is correct? And if it is not correct, why was it not correct, and how generalizable is that inaccuracy? Hannah was our eyes and ears, our boots on the ground, as she independently investigated the same question, the same task we gave Claude, to on the back end up help us determine whether Claude had indeed found the same irregularities in the original marriage dataset, and if so, what autonomous decisions had he made. And so in this episode, Hannah walks us through it, and she and Caitlin discuss both those findings, as well as begin the work of conceptualizing the process of verification in a world of AI Agents. While not definitive, this is a chance for others to hear more specifically about this. I at least anticipate that all of us will have to wrestle with verification going forward in ways we were not expecting, and maybe even are not prepared for, at least not universally, and definitely not necessarily if in fact AI Agents shrink the size of the project team members due to automation, and how best to respond to that smaller scale, and therefore, fewer people available to do the actual verification itself.

    Episode 8: Poisson Regressions (Finally)

    This week, Caitlin and Scott and Claude debate what a regression is, and then run some poisson regressions of county level marriages in Texas onto travel distance to the nearest county with an abortion provider! If that doesn’t get your heart beating fast, you should go to the doctor because you may be dead! This is a fun episode and hope you like it!

    Episode 7 of the Odd Couple: Human Verification, I mean, Hannah Verification!

    As I’ve said on here, and others have said repeatedly, the bottleneck in research is probably less so production as it is verification now that researchers have access to AI Agents like Claude Code, Gemini and Codex. But how to verify, and what to verify, is largely something all researchers will have to bumble through themselves. We did it the old fashioned way — we asked Hannah to check Claude’s work by independently going through the marriage records we found herself. In today’s episode, Hannah comes back to tell us what she found. And after today, we are now one episode closer to actually running some regressions! Famous last words.

    Episode 6 of the Odd Couple: How Will We Draw Our Diff-in-Diff?

    In this episode of the Mixtape with Scott, and season 5's "The Odd Couple", featuring Caitlin Myers and myself (Scott Cunningham), we work with Claude Code to make beautiful figures of our identification strategy -- the change in travel distance to the nearest abortion clinic caused by House Bill 2 closing half of Texas's abortion clinics. We are slowly beginning to prepare for our diff-in-diff strategy using continuous treatment, but not there yet. Scott's Mixtape Substack is a reader-supported publication.

    Episode 5 of the Odd Couple: Making Maps with Claude Code!

    Me and Caitlin Myers are back with our trusted robot command line interface secret agent with a license to kill, Claude Code! This week we continue our live research project studying the closure of abortion clinics across Texas under House Bill 2 and its effect on county marriage certificates, or the flow of new marriages. In the previous weeks, recall Claude Code helped find, pull, store locally marriage certificates — with people’s names and selected demographics for goodness sake! — and then build a panel dataset. But Claude also helped us try to understand what was going on with these date when some irregularities were spotted. And to satisfy by seemingly endless itch, Claude also made us “beautiful decks” according to my rhetoric of decks philosophy at my MixtapeTools repository that contains skills I regularly use. And the deck had beautiful pictures in it. This week we extend that exercise and make maps of Texas with more data as we continue pressing ahead to determine the relationship, potentially causal, of increased travel distance on the flow of people into marriage.
