  • Welcome to this week’s episode of the Mixtape with Scott, a podcast devoted to listening to the personal stories of living economists and creating an oral history of the profession. This episode is partly inspired by my visit to San Sebastián, Spain, with my daughter right now and partly inspired by a 2003 article co-authored with Alberto Abadie studying the effect of terrorism on economic growth that introduced the synthetic control estimator. My guest is Javier Gardeazabal, a professor at the University of the Basque Country.

    Javier Gardeazabal is a professor at the University of the Basque Country whose body of work has covered topics in macroeconomics, time series econometrics, labor economics, cultural economics, and political economy. He did his PhD at the University of Pennsylvania in May 1991, an experience that he will share about in the interview. He is from the Basque Country and returned to the Basque Country after graduation where he has been ever since. It is therefore inspiring to me that his home became the topic of a paper that he is perhaps most widely known for — a seminal contribution to both causal inference and measuring the economic costs of terrorism, coauthored with Alberto Abadie, in the 2003 American Economic Review paper, “The Economic Cost of Conflict: A Case Study of the Basque Country.” This groundbreaking study made a major contribution to causal inference by introducing the synthetic control estimator, but also assessing the economic impact of terrorism on economic growth in the Basque Country. It was a major contribution to the field possessing all the elements of great articles in economics — an important question answered extraordinarily well with clarity and rigor.

    This influential paper not only cast a massive shadow over the evolution of causal inference and econometrics; it also accelerated Javier’s own research to include not only macroeconomics, but also the economics of terrorism and conflict. His career is evidence of an economist who followed his curiosity and intellectual interests to include understanding the economic costs of terrorism, introducing methods for measuring the aggregate cost of conflict, and the impact of political violence on economic well-being, but also exchange rate dynamics, time series econometrics, cultural policies, optimal test scoring methods, gender wage discrimination and more. Javier’s versatility is evident in his ability to adapt to and excel in a variety of economic topics and methodologies, continually evolving to address new and relevant economic issues.

    Thank you again everyone for supporting the podcast and the substack. I hope that this interview speaks to you wherever you are, whenever you are.

  • Welcome to this week’s episode of “The Mixtape with Scott”! My podcast tries to capture the personal stories of living economists and create an oral history of the profession from the narratives. And this week, I’m thrilled to welcome Dr. Avinash K. Dixit, a distinguished economist whose life’s work has influenced many fields within economics. But let me start by telling you a little about his background.

    Dr. Dixit is the John J. F. Sherrerd ’52 University Professor of Economics Emeritus at Princeton University. He also serves as a Distinguished Adjunct Professor of Economics at Lingnan University in Hong Kong and is a Senior Research Fellow at Nuffield College, Oxford. For his many contributions to science, he has been awarded numerous accolades, including election to the American Academy of Arts and Sciences, the National Academy of Sciences, and the American Philosophical Society. He was also honored with India’s Padma Vibhushan in 2016, recognizing his outstanding contributions to literature and education.

    As he will share, he was born in Mumbai, India and attended St. Xavier’s College where he earned a degree in Mathematics and Physics. Afterwards, he earned another degree (also in mathematics) from Cambridge before going to MIT to get his PhD where he was supervised by the late Robert Solow. After graduation, he went to Berkeley, Oxford, Warwick and then Princeton where he’s been since 1981. Both the sheer number of contributions he has made to many fields, but also their influence, is incredible. I put in the title for this episode simply “Microeconomics” after his name, but that was a difficult decision as his work spans microeconomic theory, game theory, international trade, industrial organization, and public economics, just to name a few. I could’ve written any one of those and it would’ve still been inadequate. His recent work continues to address pressing global issues, such as optimal policies for green power generation and the dynamics of social, political, and economic institutions. He is an example of someone who follows his heart and his mind, even taking risks throughout his career to leave entire fields of inquiry in search of more questions.

    In addition to his long list of scientific manuscripts, there have also been many influential books, both textbooks but also more ones aimed at a broader population of readers. Things like “Theory of International Trade” (with Victor Norman), “Investment Under Uncertainty” (with Robert Pindyck), “The Art of Strategy” (with Barry Nalebuff), and “Games of Strategy” (with Susan Skeath and David Reiley).

    So I’ll stop there and turn it over to the show’s host — myself — and my guest, Dr. Dixit. Thank you for tuning in to this episode of “The Mixtape with Scott.” If you enjoy our conversation, please share the podcast and help us continue to bring you stories from the world of economics.

  • Welcome to this week’s episode of "The Mixtape with Scott”! This podcast is dedicated to capturing the personal stories of living economists and creating an oral history of the profession through these narratives. This week, I’m excited to welcome David Autor, an esteemed labor economist from MIT, where he serves as the Daniel (1972) and Gail Rubinfeld Professor, as well as the Margaret MacVicar Faculty Fellow. He was also last year's VP of the AEA, is on the Foreign Affairs board of the US State Department, and is a Digital Fellow at Stanford Digital Economy Lab. The number of accolades is too numerous to list, though, so I will just say that David's pioneering work in labor economics, particularly on the impact of trade, technological change, and the computerization of work, has significantly shaped and re-shaped our understanding of these critical areas.

    David Autor is perhaps best known for his influential research on the economic impacts of globalization and technological advancements. His groundbreaking study with David Dorn and Gordon Hanson on the effects of Chinese trade on U.S. labor markets highlighted the deep and often painful economic adjustments faced by local labor markets exposed to import competition. Additionally, his work on the computerization of labor, including studies on skill-biased technological change, has provided crucial insights into how technological advancements reshape the labor market and wage structures.

    One of the things you’ll learn in the interview, just as a teaser, is that David was mentored by Lawrence Katz and Alan Krueger, and that mentorship had a lasting effect. Not only did it changed his own human capital and trajectory, it seems also that it changed David’s own attitudes about mentorship. And although we couldn't delve into artificial intelligence in our conversation, Autor’s extensive research on the computerization of labor probably positions him as one of a handful of working economists at the moment whose voice will be kay in understanding the future intersections of AI and labor economics, and probably more than that. So with that I’ll stop, but thanks again to everyone for all your support. If you like the podcast, please share it!

  • Welcome to another exciting episode of the Mixtape with Scott! Today, I get to have on the show someone who has become something of a friend the last few years, an expert in health economics and social policy, Adriana Lleras-Muney at UCLA, a Professor of Economics at UCLA.

    Dr. Lleras-Muney's journey in economics is super impressive and even involves traveling through all the alleyways of causal inference. After earning her Ph.D. from Columbia University where she wrote a job market paper on compulsory schooling, at a time where it had just become accepted wisdom that the Angrist and Krueger 1991 article needed a fresh take. She then went to Princeton, the birth place of causal inference in labor, before making her way to UCLA where Guido Imbens had just gotten to, and who is also now one of her coauthors in a new article at the Quarterly Journal of Economics. So when I think about her story, it’s hard for me not to hear the echoes, I guess, of the history of causal inference too.

    Her academic accolades are too many to name, but I’ll name a few. She's an associate editor for the Journal of Health Economics and serves on the board of editors for both the American Economic Review and Demography. She’s also been a permanent member of the Social Sciences and Population Studies Study Section at the National Institute of Health and an elected member of the American Economic Association Executive committee. In 2017, her contributions to the field were recognized with the prestigious Presidential Early Career Awards for Scientists and Engineers (PECASE).

    But what really sets Adriana apart is her groundbreaking research. She's been at the forefront of exploring the relationships between socioeconomic status and health, with a particular focus on education, income, and policy. Her recent work has taken a fascinating turn, examining the long-term impact of government policies on children. She's been digging into programs like the Mother's Pension program and the Civilian Conservation Corps from the first half of the 20th century, uncovering insights that are still relevant today. Her work has appeared in all the major journals in economics such as the American Economic Review, Econometrica, The Review of Economic Studies, and the Quarterly Journal of Economics.

    So, all that said, I hope you find this interview as interesting as I did. The video will be posted most likely later to YouTube; my Scottish hotel has surprisingly very slow internet and I’m still downloading the video, and so will likely be uploading it too all night. But thank you again for all your support.

  • We have officially passed 100 episodes with today’s guest, and it’s wonderful to get to do it with my good friend, Manisha Shah. Manisha is the Chancelor’s Professor of Public Policy at University of California Berkeley. Manisha is an applied microeconomist who has historically specialized in topics related to health, education, gender and labor, with a particular focus on low and middle income countries. She has research appointments at NBER, BREAD, J-PAL, IZA and is also an editor at Journal of Health Economics as well as an associate editor at Review of Economics and Statistics. And if I can for just a moment tell you a little about that work, please bear with me.

    First the main area of her work that I am familiar with is the part that overlaps with my own historical research agenda in sex markets. That is because Manisha is arguably the leading expert on the economics of sex markets and has been for many years. She has published on just that topic alone in many high impactful studies like the effect of both legalizing sex work (Review of Economic Studies with me) and the effect of criminalizing it (Quarterly Journal of Economics with Lisa Cameron and Jennifer Seager), the identification of compensating wage differentials for unprotected sex (Journal of Political Economy with Paul Gentler and Stefano Bertozzi) as well as a Journal of Human Resources with Raj Arunachalam on a related topic, and more.

    But that is just her work on sex markets. There are also her many papers related to children development, like her Journal of Political Economy examining investments in human capital and child labor supply, her work on left-handedness and child development in Demography, another paper of hers looking at parents’ investments in children by their underlying ability, her AEJ: Applied looking at the impact of children’s development on their mother’s own labor supply, her work on sanitation and child development, and it goes on and on. There is also her work looking at people’s own risk preferences and how it relates to natural disasters they have experienced.

    One last thing and I’ll quit listing. But one of the things I admire about Manisha’s research is the shoe leather involved. Her usually involves primary data collection, running randomized field experiments, working directly with stakeholders, in places like Uganda, Mexico, India, Tanzania and more.

    It’s such a nice treat, then, to get to interview her for the 100th episode, not just because I get to share her personal story to those who only know her by reputation, but also because I count her as one of my closest friends inside and outside the profession. We worked together on a study about the legalization of sex work in Rhode Island that took around ten years from start to completion to publication. It was during a difficult time for me personally and working on that project with her meant a lot to me everyday, but more than that, working with her meant a lot to me everyday. She says in the interview that me and her similar in that we are both intense and very into our projects, and that’s true. But I guess I never really noticed that about her — all I have ever seen with Manisha is someone who is unbelievably kind, unbelievably fun and funny, unbelievably down to earth, non-judgmental, approachable, disarming, insightful, and hard working. All I can is that she has never once made me feel anything other than better about myself. Being around her, being friends with her, I mean, always leaves me feeling better than I think I would feel without her, and for that I am beyond grateful for her presence in the world. Forget the profession — in the world. So with that let me introduce you to her.

  • Greetings listeners! It is a pleasure to introduce this week’s guest on the podcast, Ashesh Rambachan, an assistant professor of economics at MIT. I wanted to talk to Ashesh for two main reasons. First, because I wanted to, and second, because I was aware of some of his recent work in econometrics. His recent article on evaluating the fragility of parallel trends in difference-in-differences just came out in the Review of Economic Studies. I’m also intrigued by his work with Sendhil Mullainathan on machine learning, algorithmic fairness as well as generative AI. Having a specialist in both causal inference, artificial intelligence and machine learning is rare, so I thought sitting down with him to learn more about his story would be a lot of fun, not just for me, but for others too. With that said, here you go! I hope you enjoy the interview! Thank you again for all your support!

  • This week’s guest on the Mixtape with Scott is esteemed labor economist, Henry Farber, the Hughes-Rogers Professor of Economics at Princeton University.

    Dr. Farber’s accolades are numerous: a Fellow of the Econometric Society, the Society of Labor Economists, and the Labor and Employment Relations Association, past President of the Society of Labor Economists, and recipient of the 2018 Jacob Mincer Award for Lifetime Contributions to the Field of Labor Economics. You can find more information about his background here in this short biography.

    But ironically, it was for a different reason that I wanted to reach out to him. I was interested in reaching out to Dr. Farber because of his traditional approach to labor economics, such as his seminal work on labor unions and the behavior of New York City taxi drivers (to name just two). His research provides a distinct perspective on labor economics, one that doesn't fall squarely into the natural experiment momentum of his contemporaries at Princeton, despite being part of the Industrial Relations Section there. I hope you enjoy this interview as much as I did! Thank you again for all your support!

  • This week's episode of "The Mixtape with Scott" features an insightful conversation with E. Glen Weyl, a distinguished economist whose career has spanned academia and industry. Glen earned his PhD from Princeton, spent three years at the Harvard Society of Fellows, and served as an assistant professor at the University of Chicago, where he made significant contributions to micro theory applications to industrial organization. However, Glen’s journey took a transformative turn when he left academia to join Microsoft, where he currently leads the Plural Technology Collaboratory, focusing on technological solutions for societal cooperation.

    Many listeners might recognize Glen from his influential book "Radical Markets," co-authored with Eric Posner. This work introduced the innovative voting mechanism known as quadratic voting, reflecting Glen's deepening interest in democratic processes and governance. His latest book, "Plurality: The Future of Collaborative Technology and Democracy,” (Amazon link) co-authored with Taiwan's Digital Minister Audrey Tang, serves as a manifesto for harnessing digital technology to foster social unity and diversity. The book presents bold ideas, from digitally empowered communication to transforming global trade, aiming to enrich relationships and ensure inclusivity.

    In addition to his writing, Glen has also ventured into film as an executive producer of the documentary "Good Enough Ancestor," which highlights Audrey Tang's work in digital democracy. That trailer can be found here; Glen was executive producer on it.

    Throughout our interview, Glen shares his experiences and insights from his varied projects, illustrating his renaissance man persona. From his academic roots to his pioneering efforts at Microsoft and beyond, Glen’s story is a testament to his innovative spirit and dedication to leveraging technology for societal good. This episode promises to be an engaging exploration of his remarkable career and visionary ideas.

    So thank you for once again for tuning into the podcast! I hope you enjoy this interview as much as I did. Don’t forget to subscribe, follow, all that and tell people about it!

    Thank you for reading Scott's Substack. This post is public so feel free to share it.

  • This week on the podcast, Matthew Jackson from Stanford University is the guest and it was such a delight for me to talk to him and get to know his story a little better. I’d met him before, but only briefly, but I’d read a lot of his work because I once developed and taught a class on networks for our masters of economics students. His textbook on the economic and social networks is excellent but he also has a general interest book on networks if you’re wanting something more accessible.

    As the podcast is technically both listening to the stories of living economists and an oral history project, maybe it is worth noting this (though I think it’s obvious to most listeners) that Matt is a micro theorist whose work has empirical content. Not all micro theory does and not all empirical work is necessarily theoretically driven, which is why I make that technical distinction. Networks are also, I think, so clearly an important part of human existence. We make friends, we catch diseases, we learn about opportunities (and maybe as importantly, don’t learn about opportunities) because of networks. And so in a very real sense, even the classical definition of economics proposed by Lionel Robbins, that economics is the study of the allocation of scarce resources by people with unlimited desires, can alone justify the study of networks if networks, as opposed to merely markets and market prices, are actually an important part of that resource allocation process itself. It’s so interesting — as someone nearly 50 to consider all the ways economics evolved over the last 50 years and continues to evolve while still remaining at its core connected to core questions like “how do humans manage to survive on this planet given they have so little time and so little resources?”

    Anyway, one last thing. At the end of the podcast, I ask Matt about his new work on artificial intelligence. The paper is at PNAS and is currently unlocked. It’s entitled “A Turing Test of Whether AI Chatbots are Behaviorally Similar to Humans” and it’s by Matt, Qiaozhu Mei, Yutong Xie, and Walter Yuan. They had ChatGPT-4 play a variety of classic games, like dictator games, prisoner’s dilemma, and so on. And they mapped the way the chatbot played to the way humans have planed these games in the lab. The one thing that I found really interesting in what they found was that ChatGPT-4 is altruistic. “It” appears to play the game altruistically in the sense that it attempts to maximize a weighted average of both its payouts and its opponent’s payouts. What then should we expect if we in the long run end up with a network of chatbots? Hard to say what the general equilibrium will be as game theoretic equilibria are often surprising and not immediately intuitive and usually depend on institutions and incentives, but still it’s quite fascinating to me. I hope you liked this interview!

  • Welcome to this week’s episode of the Mixtape with Scott where I get to interview Bruce Sacerdote, the Richard S. Braddock 1963 Professor in Economics at Dartmouth. Bruce is a prolific labor economist whose work spans the range of crime, education and peer effects. Some of his papers have been some of my favorite, even. His early work on crime with Ed Glaeser used to really interest me. But it was his work on peer effects that I found really fascinating. This old paper in the QJE about how friendships form I must have read almost 20 years and it still sticks in my head.

    I think Bruce, though, was one of the first people that I ever encountered after graduating that was very clearly part of this credibility revolution. His papers, if it used instruments, typically would use lotteries as instruments. Or if he was studying peer effects, it was lotteries. Well, not surprisingly, Bruce was there at Harvard as a PhD student in the first class that Imbens co-taught with Don Rubin on causal inference. His classmates in that class were Rajeev Dehejia and Sadek Wahba, authors of classic applied papers on the propensity score. In fact, Bruce’s own project for that class was also published — a paper estimating the causal effect of winning lottery prizes on labor market outcomes (published in the 2001 AER). So this was fun, and I hope you enjoy it too. Apologies I ramble for so long at the start. Not sure what got into me.

  • This week’s guest on the Mixtape with Scott is someone I’ve admired for a very long time, even before I entered graduate school in 2002. Peter J. Boettke is the Distinguished University Professor of Economics and Philosophy, the Director of the F. A. Hayek Program for Advanced Study in Philosophy, Politics and Economics and the BB&T Professor for the Study of Capitalism at the Mercatus Center at George Mason University. It’s hard to summarize just how important Peter has been to the story of Austrian economics, but in my mind, he’s been one of the most influential people in that long tradition, both for his scholarly work on political economy, public choice and institutions, his leadership at George Mason, where the Austrian tradition has continued to thrive, and as a mentor to young people.

    I can only speak to myself, but I have looked up to Peter for a very long time as it was always very clear that he was a humble and serious scholar who also gave an incredible amount of time and mentorship to his students. All of those are to me examples of what I find to characterize some of the best of the profession’s larger story, and so it was a real pleasure for him to sit down with me to talk about his career. I found it so interesting to hear his story in his own words, the economists he looked up to as a young person, his genuine love of economics, as a field, and how much he holds up his students and colleagues. Thank you, as always, for taking the to tune in. I hope you enjoy this time with Peter as much as I did.

  • This week’s guest on the Mixtape with Scott is Jesse Rothstein, the Carmel P. Friesen Chair in Public Policy at UC-Berkeley and the Faculty Director of the California Policy Lab. Jesse has a long list of things to which he’s made meaningful contributions, ranging from labor economics, to discrimination, to education, to causal inference and more. He’s also one of the “students of David Card” guests that I wanted to have on the podcast, as Card was his adviser way back in the day. For those curious about the paper we are talking about towards the end (“augmented synthetic control”), it’s one of my favorites in the synthetic control literature. The link to it is here. Good luck everyone this week and thanks for tuning is as always!

  • Welcome to the Mixtape with Scott! We are getting closer to the hundredth episode! This is our 91st interview if I include Adam Smith (played by ChatGPT-4), which I absolutely will be counting. And the guest is someone I have admired for a long time — Martin Gaynor, or “Marty”. Marty is the J. Barone University Professor of Economics and Public Policy at Carnegie Mellon both in the economics department and their policy school, Heinz College. But he is also special adviser to Jonathan Kanter, assistant attorney general for the Antitrust Division at the federal Department of Justice, and it is not the first time that Marty has served in government as a public servant. He is also a former Director of the Bureau of Economics at the U.S. Federal Trade Commission. You can read some about his new position in the Department of Justice here.

    Marty works on the supply side of health, you might say, as opposed to the demand side. He studies markets and concentration, hospitals, firm competition, pricing — not just our health behaviors, but also the supply of healthcare through a mixture of market and non-market processes. If you go through his vita, you can see he’s racked up a lot of awards and publications over the years.

    There are many things you can say about Marty, and after this interview, two came to mind — resilient and kind. It was actually almost not the case that he would become as successful as an economist as he became, as he will share in this interview. He struggled initially to get a tenure track job, and even left academia briefly as a result. He is remarkably upbeat and realistic about the good fortune that he has had, though. And as you will see in this interview, it is very clear that he is a genuinely kind and warm hearted person.

    Marty also is a survivor in a more literal sense. He was nearly murdered in the antisemitic terrorist attack at the Tree of Life synagogue in Pittsburgh. That is his story to tell in this interview, not mine, but I will leave it at that.

    All of our stories matter. No matter who is listening or reading this, their personal story matters, and I hope that this interview is interesting and that you enjoy getting to know Marty a bit better. Thank you for all your support!

  • Welcome to the 12th episode of the third season of the Mixtape with Scott, a podcast devoted to listening to the stories of living economists. This week's guest is Daniel Chen, an economist at the Toulouse School of Economics. I had a chance to meet Daniel when he came to Baylor and presented to use a tour de force of his body of scholarship, and I was mesmerized by it. Except for one other person, I had not met someone with that level of productive scholarly energy before. I was really stunned by how much work he had crammed into a career, spreading so many topics, and yet all held together under this umbrella of "political economy".

    I knew of many of Daniel's works by reputation and one in particular we discuss which is about a law and economics program that trained federal judges, but I hadn't met him before, and I did not put two and two together that he had gone to MIT and had on his committee Bannerjee, Duflo, Kremer and Angrist -- four key Nobel laureates in the history of causal inference and the natural experiment movement that really captured the profession. So I asked him if we could talk and I could hear his story and he agreed.

    Daniel will share it in this talk as we go through the kind of kid he was, and probably frankly still is, a deeply curious, very meticulous, thoughtful, and creative person. We talked about his childhood, majoring in applied math at Harvard, being very drawn to theory and yet people, making economics a surprising and unexpected opportunity for him, and eventually becoming what he told me was a "data rat" who collected datasets.

    He also fits with this other part of the professional story that I’ve been wanting to share with people which are these economists that also go to law school and JDs. He after finishing MIT decided to get a JD at Harvard law school, and his explanation for it is kind of interesting because it all feels somehow unplanned and yet clearly he is, in my opinion anyway, driven by his own goals. I loved meeting him, loved talking to him, loved listening to his story, and I hope you do too! Thank you for tuning in as always!

  • Welcome to the Mixtape with Scott! To set up this week’s guest, let me just share real quick a personal anecdote. When I graduated college, I got a job as a qualitative research analyst doing focus groups and in-depth interviews. I had majored in literature, so this was my first exposure to anything related to the social sciences. I loved the freedom the job gave me to collect my own data and develop my own theories about why people did the things they did.

    In the evenings I would read articles and books in sociology and anthropology as I felt more grounding in the social sciences could help me in doing a better job. One night I read Gary Becker’s Nobel Prize speech, “The Economic Way of Looking at Life”, at the University of Chicago’s John M. Olin working paper series. I was hooked. By the time I finished his speech, I knew I wanted to be an economist. But then I read other things too, like a quantitative paper by John Lott and David Mustard’s quantitative study on concealed carry laws and crime, and was equally mesmerized. And in that working paper series, I kept coming across references to someone named Ronald Coase and I then went elsewhere to learn about him and his prolific work.

    David Mustard was a Gary Becker student, and his paper on concealed carry had left an impression on me. He was an assistant professor at the University of Georgia so I applied there and one other school that used his county level crime data for studies on crime. I got into both and went with my ex-wife to visit the school and the faculty. In preparing for the trip, I read a paper by a professor at the University of Georgia named Peter Klein. The paper was entitled “New Institutional Economics” and it drew extensively on that Nobel Prize winning economist I had been learning about, Ronald Coase, another Nobel Laureate named Doug North at Washington University, and Oliver Williamson, a professor at Berkeley. The article was fascinating. It was about a field called “New Institutional Economics”, which I’d never heard of, and Klein explained it well. It was about the endogenous evolution of “institutions” to support and facilitate the organization of human interactions at a high level, most often to support commerce and trade though not just that. The ideas were deep and fascinating. I remember reading that article with a pen and highlighter, going over it and over it, hanging on every word. Not only was the topic fascinating, the author writing it was an excellent writer. There was not a wasted word in it. So when I met with the faculty, including Peter, I was sold on Georgia. But unfortunately, Peter was leaving Georgia for Mizzou and so I just barely missed being in the department with him.

    So that is a long winded bit of background into telling you that today’s guest is someone I’ve known now for over 20 years — Peter Klein, the W. W. Caruth Endowed Chair at Baylor University in the Entrepreneurship department. Peter is now a professor as well as the department chair at Baylor in our Entrepreneurship department. And so it is my pleasure to introduce you to him. Peter did a PhD at Berkeley and studied under Oliver Williamson, who I mentioned earlier. Williamson would go on to win the Nobel Prize for extending Coase’s theory of the firm and helping develop a more robust theory based on transaction cost economics. Peter’s work on the firm extends a lot of this work on transaction cost economics continues in that line focusing on the organization of the firm. He is the author of countless articles as well as a new book entitled Why Managers Matter: The Perils of the Bossless Company (with Nicolai Foss). It has been a real joy having him here since I missed him the first time around.

    As long time listeners know, though, I typically am doing a “mini-series” within the podcast, though, and Peter fits into one of those mini-series. Those mini-series are “the econometricians”, “causal inference and natural experiment methodology”, “Becker’s students”, “economists going to tech”, and then “public policy”. But another one I’m slowly picking at has to do with the wings of the profession that fall outside of the exclusively neoclassical tradition, one of which is Austrian economics. And Peter comes from that tradition, though he has mixed it with mainstream economics and made it into something of his own. So, with that being said, let me now turn you over to the podcast! Thanks again for tuning in!

  • This week’s guest on the Mixtape with Scott is famed labor economist, Richard Blundell, the David Ricardo Professor of Political Economy at the University of College at London.

    Dr. Blundell’s accolades are extensive: a Fellow of the Econometric Association, Fell of the American Academy of Arts and Science, former President of SOLE, of the Royal economic Society, recipient of the 2000 Frisch Prize, the 2020 Jacob Mincer Prize in Labor Economics, and on and on. You can find more information about his background here at this short biography.

    But ironically, it was for a different reason that I wanted to reach out to him. I was interested in reaching out to Dr. Blundell because of some research I had been doing on the history of difference-in-differences and throughout the 1990s, I kept coming back to him. He had several things he wrote in the 1990s that left me with the distinct impression that he was attempting to educate others about the bridging of causal inference and natural experiment methodologies, so I was just curious to learn more about him. I hope you enjoy this interview as much as I did! Thank you again for all your support!

  • 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!

  • 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!
