Send us a text  Jeff and Scott chat with Joe Thorndike about how the United States moved from relying heavily on tariffs to building the modern income-tax-based system we know today. Joe is a tax historian and journalist, and writes for Tax Notes, where he writes widely on the history and politics of U.S. tax policy. They walk through the political and economic forces that made tariffs both attractive—and eventually untenable—as a main source of revenue. Along the way, they discuss the creation of the federal income tax, the rise of new revenue needs, and what this history can teach us about today’s debates over trade and taxation. 

Send us a text Jeff and Scott talk with Jason DeBacker about his new paper, Learning from 25 Years of Changes in Business Tax Policy (with Aerfate Haimiti). Jason is an associate professor of economics at the University of South Carolina and the director of the Policy Simulation Library, an open-source effort that helps researchers and policymakers analyze policy. They discuss his work at PSL and what the last 25 years of business tax changes have taught us—whether bonus depreciation boosts investment, how firms respond to shifts in business tax rates, and more. 

Send us a text Jeff and Scott chat with David Mitchel, a Senior Fellow at the Washington Center for Equitable Growth, about the small business stock exclusion, recent changes to it, and an article that David wrote with Kyle Pomerleau about why we should get rid of it.

Send us a text Luke 2 tells us that Mary and Joseph went to Bethlehem "to be taxed", and while there, the baby Jesus was born. But, what do we know about that taxing from history? Did everyone travel? What was the general tax environment in the Roman world at the time? Did they actually remit a tax, or, what was the purpose of this trip? Jeff and Scott chat with Roman historian Anna Dolganov about these questions, and more. Anna's previous appearance on the show: https://www.buzzsprout.com/1878989/episodes/17860482 .  One note: On the podcast we talk about how burdensome the tax imposed by the Romans in situations like this was, in terms of days of labor (a la Tax Foundation's "Tax Freedom Day"). Here is a follow-up note from Anna: "A Roman legionary's salary was about 225 denarii per year, and the poll tax rate in Egypt was 8-40 drachmas per year (depending on location and tax privilege). So, not quite Austrian level taxation, but still quite a considerable sum." A denarii and a drachma are equivalent. So, Tax Freedom Day for Mary and Joseph, based only on the poll tax, may have been sometime in mid-February.

Send us a text Jeff and Scott talk with Justin Schein. They discuss Justin's newest film, and the issues and questions it brings up. Justin's newest film is Death and Taxes, which "is a feature documentary about wealth, inequality and the American Dream, viewed through the lens of the estate tax and the very personal story of a father and son at odds over what kind of inheritance we want to leave our kids and our country."  Learn more about the film here: https://www.deathandtaxesfilm.com/.

Send us a text Jeff and Scott chat with Ajay Mehrotra, law professor at Northwestern, about the economist Edwin Seligman. They discuss Seligman's academic legacy, his views on progressive taxation, his influence on Columbia University, his students, and his views on tax policy.

Send us a text Jeff and Scott chat with Marc Goldwein, who is the Senior Vice President and Senior Policy Director for the Committee for a Responsible Federal Budget. They chat about Medicaid, a huge piece in the federal government's budget, and an essential piece of understand what needs our tax system must satisfy. They talk about the program in general, ways in which it was recently reformed under the One Big Beautiful Bill, and what we might do to fix it going forward.

Send us a text Jeff and Scott chat with Anna Dolganov, an academy scientist at the Austrian Archeological Institute, about her work on a recently re-discovered papyrus. The papyrus contained notes from a tax evasion trial in ancient Rome, which Dr. Dolganov translated. We discuss taxes in ancient Rome, Jewish tax revolts, how to evade taxes on the goods Rome taxed (including human slaves), and what we can learn from the papyrus about the trial. 

Send us a text Jeff and Scott chat with Henry (Hank) Aaron, a Senor Fellow Emeritus at the Brookings Institution, about Social Security. They discuss how it started, how we fund it, who gets it, how it has been reformed, and how it could be fixed.

Send us a text Jeff and Scott very briefly talk about the bombshell news that podcasters are included on the Treasury's list of jobs eligible for "no tax on tips."  https://home.treasury.gov/system/files/136/Tipped-Occupations-Detailed-8-27-2025.pdf Left unexplored is whether any of the other provisions of no tax on tips will preclude Scott and Jeff from receiving tax-free tip income, by means of the credit available to offset declared tip income available in The One Big Beautiful Bill.

Send us a text Jeff and Scott talk with Kyle Pomerleau about how inflation interacts with tax policy and the tax law. Kyle points out that inflation interacts in two major ways: When we tax gains that happen over long periods of time, and we have to think about whether adjusting the gain for inflation would help, and, when the tax system includes explicit dollar values, such as in thresholds, amounts of credits, the income tax brackets themselves. 

Send us a text Jeff and Scott chat with Brad Setser, a Senior Fellow on the Council of Foreign Relations, about income shifting among pharma firms, as well as the impact that shifting has on tariffs and international trade.

Almost all of these books were a an academic bequest from one of Jeff's mentees, Joel Slemrod.   Jeff introduces four books, asks a question related to the book, and Scott tries his best at answering. The four books mentioned, and the approximate year of their original publication: Rich and Poor (1898) - Helen Bosanquet Capital (1867) - Karl Marx Political Economy (1837) - Francis Wayland  The National Revenues (1888) - Albert Shaw

Send us a text  In this episode, Jeff and Scott talk with Anders Anderson, a finance professor at the Stockholm School of Economics about, his research evaluating Sweden’s nationwide e-bike subsidy. The program successfully doubled e-bike sales, but had only a modest impact on reducing car use—far less than survey responses suggested. People bought b-bikes, then didn't really use them. When accounting for actual emissions reductions, the cost of carbon abatement was around $800 per ton, which most people agree is more than the social cost of carbon. We discuss why the policy wasn’t cost-effective and what better subsidies might look like.
