The Mixtape with Scott

Welcome to the Mixtape with Scott! Due to a technical difficulty with my producer’s computer, this week’s interview was not ready in time. So we are going to do another repeat from season one. This is with Petra Todd, a labor economist, econometrician and author of a new book on causal inference entitled, Impact Evaluation in International Development with Paul Glewwe. She was also elected to the Academy of Arts and Sciences last 2023. And she is Jim Heckman’s former student and coauthor, which fits with my slowly building deck of interviews on “Heckman’s students” (along with John Cawley and Chris Taber). But I also just loved this interview and so it’s also nice just to repost it. Plus, it’s probably nice I think to give people some breathing room given the pace at which these come out. Next week, though, I should be back on track with new episodes. Thanks again for tuning in!Scott's Substack is a reader-supported publication.

I’m still recovering from my travels over spring break, so I decided to repost an old interview I did in August 2022. This was my 27th podcast interview at the time and part of my “Economists in Tech” series, which has died down somewhat. The guest was Kyle Kretschman whose title at Spotify reads “Head of Economics”. This was a popular interview when it first came out, and I thought for newer listeners, they might like to listen to it again. Kyle came to Spotify after spending around 6-7 years at Amazon first. He graduated from the University of Texas at Austin with a PhD in economics in 2011. PhD economists going into tech in the early teens was really just at the beginning — the flow and the stock was much smaller than it is now. So it was really interesting to listen to Kyle’s story about that move away from academia into tech when it was not quite as common a story as it is now. And I think the story really resonated with a lot of people, in general, when it first came out so I thought I’d share it again. Here’s a Q&A that UT Austin did with him in December 2022 if you want to read more of his story there too. Thanks again for tuning in!Scott's Substack is a reader-supported publication.

This week’s guest on the Mixtape is Pierre Chiappori, a micro theorist at Columbia University. While Pierre is not technically a student of Gary Becker’s, there are many people who counted Becker as a colleague that probably at times did consider them also Becker’s student, and I suspect Pierre is one such person. I learned of Dr. Chiappori in graduate school while studying economics of the family. His collective models of the household always seemed a little bit outside of what I was studying, which was typically the Nash bargaining models of marriage, but I was also very interested too. It’s a run of papers he did in the 1990s, overlapping with when he was at Chicago with Becker, that sort of was the catalyst to ask him on the show. When I learned that he grew up in Monaco under the shadow of Princess Grace Kelly, and that he like me also loved Rear Window, I knew it was going to be an interesting talk. I hope you all enjoy it. Remember, the story of economics has been tributaries, many eddies, and listening all of them is in my opinion a way to show consideration to those people where consideration is nothing more than allowing their story to become real to us. I continue to believe that it is in the act of listening to stories that we are transformed and learn our own way. So I encourage you to listen closely to the story of Dr. Pierre Chiappori. Oh and this is our 87th interview. 13 more and we hit 100! Scott's Substack is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.

Welcome to season three of the Mixtape with Scott — a podcast devoted to listening to the stories of living economists and creating an oral history of the last 50 years of the profession. This week’s interview is with Wilbert van der Klaauw, economic research advisor in the Household and Public Policy Research Division and the director of the Center for Microeconomic Data with the New York Fed. Wilbert has an interesting story for many reasons. He fits with my longstanding interest in causal inference for his early work on regression discontinuity design, both alone and with Hahn and Todd in their 2001 Econometrica. But I also wanted to hear his story because of his decision to leave academia as a full professor at UNC Chapel Hill to work at the Federal Reserve. (Which again brings to mind that part of the story of the profession is the Federal Reserve itself but that’s for another day). So it was a real interesting experience to get to talk with Wilbert and hear more about his life coming from the Netherlands to study at Erasmus, where he met a young Guido Imbens — a detail I didn’t know about either — and studied econometrics as his undergraduate major (a major I also didn’t know existed apart from economics). So I hope you enjoy this interview! Scott's Substack is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.

Bruce Hansen, an econometrician from the University of Wisconsin, shares insights into his career and influences, from free textbooks to his upbringing in Southern California. The podcast covers his transition from music to social science and his journey to becoming a leading figure in econometrics, highlighting the evolution of the field and the impact of his collaborative research.

This week’s guest on the Mixtape with Scott is Christopher Taber. Chris is a professor of economics at the University of Wisconsin where he is department chair, the James Heckman professor of economics and the Walker Family chair. Chris is a labor economist and econometrician who has made numerous contributions to both areas such as the returns to education, difference-in-differences with small numbers of interventions, techniques for evaluating claims of selection on observables and more. In addition to fitting into my long running interest in econometrics and labor economics, though, I wanted to talk with Chris because this year I’m wanting to interview more “the students of [BLANK].” And Chris was Jim Heckman’s student as a grad student at the University of Chicago and this year in addition to interviewing the students of Orley, Card, Angrist and Imbens, I am also want to interview the students of Jim Heckman as I continue to flesh out the causal inference revolution that began in labor economics in the 1970s, 1980s and 1990s at Princeton, Harvard, MIT, Chicago and Berkeley. Thanks for tuning in! I hope you enjoy this chance to listen to Chris’s story as much as I did.Scott's Substack is a reader-supported publication.

Welcome to another episode of the Mixtape with Scott! This week I have a guest who some of you know, and some of you don’t know (I suppose making them no different than anyone else) — Andrew Baker. Andrew is now an assistant professor in the law school at the University of California Berkeley. He specializes in topics at the intersection of law, policy and finance. And one of his papers, “How Much Should We Trust Staggered Difference-In-Differences Estimates?”, published in the Journal of Financial Economics, was the winner of the Jensen Prize for the best paper published in Corporate Finance. He is for many people permanently part of the last five year’s or so “credibility crisis in difference-in-differences” for both this paper, as well as other things he’s written and done. So I thought it would be great to have him on the show as part of the larger material on causal inference in economics. But Andrew is not an economist. He has a joint JD/PHD from Stanford, but the PhD is in Business Administration with a special focus on accounting. I nonetheless included him in this series as part of the “story of economics” because like Carlos Celinni last week’s guest, Andrew started out in economics as an undergraduate at Georgetown, then went to work for an economic consulting firm, then did a predoc with John Donohue III, professor of law at Stanford and PhD economist from Yale. But then he instead went into Stanford’s law school before migrating into their doctoral program in business administration. And I thought this kind of story — the story of people staying in, but also of people exiting — is really a part of the larger economics story too. It’s still somewhat challenging to find these stories, so I’m going to keep trying, but I wanted to if I could by circling people who I knew it applied to. But, as with others, the point of Andrew being a guest on the show is simply because I think he does have an interesting story, and I wanted to hear it. I hope others of you hear it too.

Philosophy of the PodcastWelcome to the Mixtape with Scott, a podcast devoted to hearing the stories of living economists and a non-randomly selected oral history of the economics profession of the last 50 years. Before I introduce this week’s guest, I wanted to start off with a quote from a book I’m reading that explains the philosophy of the podcast. “For the large m majority of people, hearing others’ stories enables them to see their own experiences in a new, truthful light. They realize — usually instantaneously — that a story another has told is their own story, only with different details. This realization seems to sneak past their defenses. There is something almost irresistible about another person’s facing and honoring the truth, without fanfare of any kind, but with courage and clarity and assurance. The other participants feel invited, even emboldened, to stand unflinching before the truth themselves. By opening ourselves even a little to the remarkable spectacle of other people reconsidering their lives, we begin to reconsider our own.” — Terry Warner, Bonds That Make Us FreeThe purpose of the podcast is not to tell the story of living economists. The purpose of the podcast is to hear the stories of living economists as they themselves tell it. It is to make an effort to without judgment just pay attention to the life lived of another person and not make them some non-playable character in the video game of our life. To immature people, others are not real, and the purpose of the podcast is, if for no one else, to listen to people so that they become real, and in that process of listening, for me to be changed.They may sound heavy or it may sound even a little silly. After all, isn’t this first and foremost a conversation between two economists? But economists are people first, and the thing I just said is for people. And let’s be frank — aren’t man of us feeling, at least some of the time, alone in our work? And isn’t, at least some of the time, the case that our work is all consuming? I think there are people in my family who still don’t understand what my job is as a professor at a university, let alone what my actual research is about. There are colleagues like that too. Many of us are in departments where we may be the only ones in our field, and many of us are studying topics where our networks are thin. And so loneliness is very common. It is common for professors, it is common for students, it is common for people in industry, it is common for people non-profits and it is common for people in government. It is common for people in between jobs. And while the purpose of the podcast is not to alleviate loneliness, as that most likely is only something a person can do for themselves, the purpose is to share in the stories of other people on the hypothesis that that is a gift we give those whose stories we listen to, but it’s also maybe moreso the gift we give the deepest part of ourselves.

Carlos Cinelli may seem like a guest who does not quite fit, but his is the story of the economics profession in a couple of ways. First, he is someone who left economics. Carlos was an undergraduate major in economics who then did a masters in economics and after doing so left economics (and econometrics) to become a statistician. The leaving of economics is not the road less traveled. By talking to Carlos, and hearing his story, the hope is that the survivor bias of the podcast guests might be weakened if only a tad bit. But Carlos also fits into one of the broader themes of the podcast which is causal inference. Carlos studied at UCLA under two notable figures in the history of econometrics and causal inference: Ed Leamer in the economics department and Judea Pearl in the computer science department. And Carlos is now an assistant professor at University of Washington in the statistics department whose work consistently moved into domains of relevance in economics, such as his work in the linear of econometric theory and practice by Chris Taber, Emily Oster and others. That work is important and concerns sensitivity analysis with omitted variable bias. And he has also written an excellent paper with Judea Pearl and Andrew Forney detailing precisely the kinds of covariates we should be contemplating when trying to address the claims of unconfoundedness. So without further ado, I will turn it over to Carlos. Thank you again for your support of the podcast. Please like, share and follow!Scott's Substack is a reader-supported publication.

The Mixtape with Scott is a weekly podcast devoted to building out a selected part of the collective story of the last 50 years of the economics profession by listening to the personal stories of living economists. And this week's guest is a the John G. McCullough Professor of Economics at Middlebury College in Vermont, Caitlin Myers who I am fortunate to count as both a coauthor and friend, as well as an professional admirer. Caitlin is a graduate of the University of Texas's economics department and is one of those young economists who hit the ground running and has only gotten faster. A senior economist told me recently she is *the* abortion researcher at this moment in time having made major contributions to both the scientific record and the policy discussion regarding abortion policy, its causes and its consequences. She is as far as economists go meticulous, thoughtful, passionate, principled and creative, and while she is not directly a student of Gary Becker, or Claudia Goldin for that matter, she is very clearly part of their influence on labor economics and on Caitlin in turn.
