The Mixtape with Scott

Greetings from San Sebastián Spain where I am on holiday with my daughter for another couple of weeks. I have still not done any new podcasts as I realized only after I left that I did not pack my microphone. And, I didn’t want to buy a new one, and I wasn’t really 100% positive if using my Apple AirPods would work well. All of that is to say — excuses.So, this week we are going back down memory lane to an interview I did 1-2 years ago with one of my favorite young up and coming econometricians, Tymon Słoczyńsi from Brandeis University. Tymon is the author of a wonderful 2022 article on OLS models with, I’ll call it, “additive and separable” covariates under unconfoundedness. Autocorrect wanted that to be “addictive” instead of “additive”, which would’ve been a really clever Freudian slip. Tymon’s interview was one of my favorites. I know I say that about every interview, but they all feel like that, but let’s just this one really really feels that way. And I think you’ll feel the same way. One of the things I love about Tymon’s articles is how excellent the writing is. His paragraphs oftentimes feel like the kind of paragraphs that you can tell he wrote, and rewrote, and rewrote, and rewrote like a hundred times. It amazes me that English is not his first language and he writes this well. I don’t even mean this clear — I mean it’s beautiful writing. Here’s a paragraph I think is outstanding, for instance:“To aid intuition for this surprising result, recall that an important motivation for using the model in equation (1) and OLS is that the linear projection of y on d and X provides the best linear predictor of y given d and X (Angrist & Pischke, 2009). However, if our goal is to conduct causal inference, then this is not, in fact, a good reason to use this method. Ordinary least squares is “best” in predicting actual outcomes, but causal inference is about predicting missing outcomes, defined as ym = y(1) × (1− d ) + y(0) × d. In other words, the OLS weights are optimal for predicting “what is.” Instead, we are interested in predicting “what would be” if treatment were assigned differently.”A lot of his sentences are sentences that are so precise, so insightful, that I wish I could have written it. It’s superb, he’s superb, and if you haven’t listened to this, I hope you do, and if you already have listened to it, then I hope you listen to it again.Thanks again for all your support. Wish me luck as I wrap up my summer in Europe, start making my plans to move to Boston, teach new students, meet new colleagues, and make new friends. And get some new clothes to replace the ones the gentleman who stole my luggage on the train in Switzerland is now in possession of. Scott's Mixtape Substack is a reader-supported publication.

Welcome to the Mixtape with Scott — an interview-based podcast where I, Scott Cunningham, talk to living economists about their personal lives. I continue my travels in Europe without a good microphone, which has caused me to delay my newest interviews a little bit longer. Therefore this week’s episode is an oldie but a goodie — Jon Roth, a young econometrician at Brown University. Jon has had many high profile publications to his name already in a short period of time, many of which center around difference-in-differences. Several have focused on the event study (e.g., here, here and here) , whereas others have focused on the logarithm both within diff-in-diff but also outside of it. I think it is fair to say that Jon’s econometric contributions have been unusually practical to applied researchers while also scientifically robust and accurate. I remember enjoying this conversation with Jon a great deal, and if you haven’t listened to it, it’s a great time to do so now, and if you have listened to it, it’s a great time to listen to it again!

Mohammad Akbarpour, an economic theorist at Stanford University, shares his fascinating journey from Tehran to academia. He reflects on his early life in Iran, the competitive educational landscape, and the cultural dynamics of pistachio farming. The conversation touches on his transition from electrical engineering to economics and how mentorship shaped his career. Akbarpour also explores the unique kidney market in Iran and the interplay between economics and computer science, offering fresh insights into social networks and disease dynamics.

Welcome back to The Mixtape with Scott, a podcast about the lives and stories of living economists. This show often unfolds in themed mini-series, and lately I’ve been exploring one that I’ve been curious about for a while: the economists who navigated and participated in the heterodox tradition in economics. Today’s guest is Amitava Krishna Dutt, a development economist, now emeritus at the University of Notre Dame. His work sits at the intersection of structuralist macroeconomics, post-Keynesian theory, and development, with deep engagement in political economy. He’s long been committed to questions of global inequality, the dynamics of capitalist growth, and the limitations of orthodoxy in addressing the needs of the Global South.So thank you for tuning in. I hope this is as interesting to you as it was to me.Scott's Mixtape Substack is a reader-supported publication. To receive new posts and support my work, consider becoming a free or paid subscriber.

Welcome to this week’s episode of The Mixtape with Scott. Today’s podcast guest is our 127th guest on the show—Vitor Possebom, Assistant Professor in the Department of Economics at the Fundação Getulio Vargas. Vitor’s research sits at the intersection of two areas — econometrics and causal inference, and policy evaluation in Latin America, particularly Brazil. His contributions revolve around refining and extending tools for estimating causal effects in observational data, especially under common data imperfections like selection bias, measurement error, and treatment effect heterogeneity.* Sample selection and marginal treatment effects (e.g., “Identifying Marginal Treatment Effects in the Presence of Sample Selection” (Journal of Econometrics), “Crime and Mismeasured Punishment” (Review of Economics and Statistics))* Misclassification and measurement error (e.g., “Potato Potahto in the FAO-GAEZ Productivity Measures?”)* Inference and sensitivity in synthetic control methods (e.g., “Cherry Picking with Synthetic Controls”, “Synthetic Control Method: Inference, Sensitivity Analysis and Confidence Sets”)* Probability of causation in non-experimental settings (e.g., “Probability of Causation with Sample Selection”)I invited Vitor onto the podcast because of his creative contributions to causal inference, as he fits into a larger informal series I’ve been for the last several years on causal inference in general. In today’s conversation, we talk about Vitor’s path from Brazil to Yale University and then back. Vitor, thank you so much for joining us.Scott's Mixtape Substack is a reader-supported publication.

Welcome to The Mixtape with Scott, a podcast dedicated to exploring the personal stories of living economists. I'm your host, Scott Cunningham, Professor of Economics at Baylor University.Today, I'm delighted to introduce Jessica Brown, Assistant Professor of Economics at the Darla Moore School of Business at the University of South Carolina. Jessica is also a Research Fellow at IZA and a Faculty Affiliate at the Wilson-Sheehan Lab for Economic Opportunities.I invited Jessica onto the podcast because of her deep connections to the credibility revolution, causal inference, and the esteemed tradition of labor economics nurtured at Princeton University’s Industrial Relations Section, where she completed her PhD in 2019.Jessica is also joining us as part of a special series I've been hosting, loosely titled "The Students Of..." Within this series, she specifically contributes to our "Students of Alan Krueger" mini-series. Alan Krueger, a pioneering economist whose work profoundly shaped labor economics, tragically passed away in 2019. Jessica was one of Alan's last doctoral students, and his death came shortly before her dissertation defense.In our conversation today, we'll explore Jessica's journey as an economist, her experiences studying under Alan Krueger, and the influence he had on her professional and personal development.Jessica, thank you so much for joining us.Scott's Mixtape Substack is a reader-supported publication.

Welcome to this week's episode of The Mixed Tape with Scott. I'm your host, Scott Cunningham. This podcast is devoted to the personal stories of living economists, diving into their lives, careers, and the fascinating paths they've walked.This week's guest is Michael Anderson, an economist from the University of California Berkeley's Department of Agricultural Resource Economics. Michael earned his PhD at MIT in 2006 under the mentorship of Josh Angrist, making him part of a broader narrative I've been exploring—the Princeton Industrial Relations Section and the influential lineage of scholars who shaped the modern credibility revolution in economics.In our conversation, we touch on Michael's rich and varied research. We discuss his insights into the returns to college athletic success, delve into his foundational work on the Perry Preschool program and the challenge of multiple inference, and explore the real-world impacts outlined in his American Economic Review paper on subway strikes and slowdowns. As always, though, this episode is much more than just research highlights—it's about Michael's journey through economics, his stories, and the experiences that have defined his path.

I’m thrilled to announce that our next guest on The Mixtape with Scott is Professor Philip Oreopoulos—one of the most impactful economists working today in education and labor. A PhD student advisee of David Card, Phil is part of the distinguished lineage that helped shape the credibility revolution in applied microeconomics.Now a Professor of Economics and Public Policy at the University of Toronto, Phil has spent his career studying how education policies and interventions affect outcomes for students and workers. His work blends rigorous causal inference with real-world relevance to uncover how both the very large interventions we employ to help society, as well as the seemingly surgically narrow ones, shape the lives of workers and students. He’s also a Research Associate at the National Bureau of Economic Research and a Research Fellow at the Canadian Institute for Advanced Research. His CV is full of important papers, but it’s the heart behind the work that really stands out—his curiosity about the world and his desire to make a difference. In this episode, we go beyond the papers. We talk about his journey, what it was like working with David Card, and how he found his calling. It’s a thoughtful, warm conversation with a scholar who represents the very best of what economics can be.Scott's Mixtape Substack is a reader-supported publication.

I'm excited to announce the newest episode to the podcast features a brilliant mind in econometrics and applied microeconomics: Dr. Liyang "Sophie" Sun from University College London. While Liyang has technically been a guest before, our previous conversation had been narrowly focused on econometric techniques. This time, we're shifting gears to align with the core purpose of the podcast—exploring the personal stories and journeys of living economists.Many of you know Liyang by reputation or have cited her groundbreaking work. Her 2021 paper with Sarah Abraham in the Journal of Econometrics on difference-in-differences estimated using two-way fixed effects with leads and lags was recognized as one of the recipients of the Aigner award for 2022 —a remarkable achievement. That paper in particular helped clarify exactly what we were—and weren't—measuring in difference-in-differences event studies. Beyond diagnosing issues in existing approaches, they introduced a new and more accurate estimator, known formally as the interaction-weighted estimator, but which most of us now fondly call simply “SA” (Sun and Abraham). I love that paper; it has taught me a great deal.Her research portfolio extends well beyond this, spanning instrumental variables, synthetic control methods, and other innovative approaches that have reshaped how we think about causal inference in economics.In this episode, we'll dive into Liyang’s personal journey through growing up in China, coming to the United States as a high school student, and then through college, grad school and a career as a professional economist and econometrician. She generously shares the experiences, people and discoveries that have shaped her career and research directions. It was a genuine pleasure to hear more of her story, and I believe you'll find it both enlightening and inspiring.Thank you again for all your support!

Welcome to the Mixtape with Scott! This week’s guest is Nathan Nunn, professor in the Vancouver School of Economics at University of British Columbia. Nathan is a development economist and economic historian whose work on the development of the African continent has been viewed as pioneering, seminal even. Two of his major works focused on the African slave trade and its impact on trust (here in this AER) and the continent’s longterm development (here). The body of work is so massive that I can only point you to his webpage and vita. He’s currently an editor at Quarterly Journal of Economics, a member of NBER and a research fellow at BREAD. And here is his google scholar page. And for giggles, here are the people at NotebookLM explaining his vita!Here’s that NotebookLM link for people looking on YouTube or podcast platforms like Apple Music or Spotify. url: https://notebooklm.google.com/notebook/ac825f4e-3e35-4359-b154-bc82ef808a79/audioThanks again everyone and I hope you enjoy this great interview!
