How Early Access to Trump’s Truths Will Drain Ordinary Investors | Diving In Aug 06, 2026

Show notes

Justin unpacks the new $100,000-a-year Truth Social API—a special "pipe" that will allow the president's posts to hit Wall Street computers a second or so before the rest of us see them. In this episode of Diving In, he explains why one second is an eternity for a high-frequency trading computer: it can read a post announcing a strike on Iran, figure out what it means for markets, and sell before the news reaches your phone.

Justin lays out three problems. It's bad for democracy — a decision your taxes paid for gets sold to whoever writes a six-figure check, to a company in which President Trump is a major shareholder. It's corrupt on its face — the president is monetizing information he holds only because he works for you. And it's bad economics: once you know some traders have paid for an edge (remember teleprompter guy?), you stop wanting to trade at all, and markets that run on trust start to wither.

At the end of the day, those Wall Street firms will get rich, and that money has to come from somewhere. And if you're not the one with the early feed, it's probably coming from your retirement account.

(A confession: I think that I said that users pay the President's company $100,000 per year. I've subsequently read the price is $100,000 per month. So it's still a problem, but 12 times larger.)

What Victorian Bootmakers Can Teach Us About The Future of Work | Diving In Aug 05, 2026

Show notes

When the CEO of Anthropic warns AI could wipe out half of all entry-level white-collar jobs, it's easy to picture the destruction. Justin Wolfers wants you to picture the other half of the story. In this episode of Diving In, he uses a carefully researched study of Victorian bootmaking — where a labor-saving sewing machine let each worker make four times as many boots — to show how a technology can completely remake an industry while total employment barely moves.

The numbers are almost eerie: about 220,000 bootmakers in 1851, and 213,000 in 1911. Yet beneath that calm surface, nearly everything changed. Cheaper boots meant more boots (that's Jevons paradox), old craft occupations vanished, and an almost identical number of new factory jobs appeared — in new places, done by the next generation. The incumbents mostly got to retire in their old trade.

None of this predicts what AI will do to your job. But it widens the range of outcomes you should take seriously, and it flags the one thing that may matter most: the pace of change. If AI moves slowly, the creative side of creative destruction has time to arrive. If it moves fast, that gentler adjustment gets much harder. Either way, it’s important to also ask what gets created, not just what gets destroyed.

Economics Is Not a Subject — It's a Toolkit | Economics Matters Aug 04, 2026

Show notes

This is a conversation between Justin and Larry Kotlikoff, fellow economist and host of the Economics Matters podcast. And it was a fun one, in which Larry encouraged Justin to look both backwards and forwards. Backward at some of the work he's most proud of, and forward at the growing challenges we face as an economy and a nation.

In the process, Justin and Larry philosophized over the role of economics and the duty of economists in helping tackle some of the most pressing issues of our time. This was the kind of conversation that reminded Justin why he fell in love with economics: it’s not the models or the math, but the chance to make sense of the lives we actually live.

Tariffs, Take Three: The Dumbest Round Yet | Off the Clock Aug 02, 2026

Show notes

Justin and Stacey are back for Off the Clock — helping you figure out what economic news to actually worry about, what you can safely ignore, and where to find some silver linings.

This week was a big one for economic news and data. Justin starts by explaining to Stacey why this latest round of tariffs is the dumbest one yet. And Stacey brings in some reporting to highlight how small businesses are struggling under the weight of constant chaos and confusion.

Then they dig into the Fed and why markets reacted so poorly to Handsome Kevin’s press conference. Finally, Justin and Stacey discuss the latest, lackluster GDP numbers and compete in a “Chart vs. Chart” contest that you get to be the judge of.

How SNAP's New Rules Make Eligible Families Go Hungry | The Professor Is In Aug 01, 2026

Show notes

Recent changes to SNAP quietly cut food assistance from 4 million Americans — 1.5 million of them children (plus elderly, disabled, and other eligible recipients who were never the intended target). In this follow-up to his earlier video Diving In to SNAP cuts, Justin Wolfers answers follow-up questions and explains how the policy actually plays out for real people.

Justin walks through why administrative burdens do so much damage: when it's harder to apply, appeal, or bring in paperwork, the people who fall off are often the ones who need help the most. He unpacks the state incentives too: tell caseworkers to reduce payment errors but say nothing about wrongful denials, states get cautious and just boot folks off. And because states run balanced budgets, shifting SNAP costs to them breaks its role as an automatic stabilizer — in the next recession, when more people need food, spending will fall exactly when it should rise.

The stakes are personal. That $6-a-day benefit is groceries for a neighbor, a kid at your child's school, a friend going through a divorce whose income just cratered. And Justin's argues that if Americans understood who's losing help and why, they might feel differently about it.

The Lawyer’s Theory of Trade | Diving In Jul 29, 2026

Show notes

Donald Trump's trade representative Jamison Greer thinks about trade like a litigator: clients, injuries, bad actors, and remedies. Justin Wolfers takes Greer's own words from his recent interview with The Daily and shows why that worldview rests on muddled thinking about what trade actually is — and why it ends up costing you.

In this Diving In episode, Justin lays out the tells and discusses the bottom line. The numbers are blunt: New York Fed research finds roughly 90% of the tariff burden falls on U.S. firms and consumers, and low-income households bear a disproportionate share. Census data shows imports from China fell — but rose nearly one-for-one from the rest of the region. A lot of trade just changed addresses.

By the end you'll have a portable BS detector for any trade argument — from Trump, Vance, Greer, or your uncle at Thanksgiving.

Should Canada answer Trump's tariffs? | The Professor Is In Jul 25, 2026

Show notes

In this episode of The Professor Is In, Justin Wolfers digs into the latest tariffs on Canada, answering subscriber questions and responding to comments from his earlier Diving In He addresses the suspicious timing of these new tariffs, break down the confusing dairy tariff-rate quota, and argues that total US-Canada dairy trade — about a billion dollars against hundreds of billions in overall trade — isn't worth blowing up either economy over.

On whether Canada should retaliate, Justin borrows Joan Robinson's "rocks in the harbour" metaphor: most of a tariff's cost lands on the country imposing it, so matching Trump would mostly hurt Canadians.

Finally, Justin discusses the biggest issue: trust. Once a president tears up a deal he signed, the value of his next signature is zero — and that discourages the deep, long-run cross-border investment that has defined North American trade over the past several decades.

Six Dollars a Day Is Disappearing For Millions | Diving In Jul 22, 2026

Show notes

Last summer, Congress passed one of the biggest cuts to food assistance in a generation. SNAP — the program a lot of folks still call food stamps — pays about $188 a month, roughly $6 a day for groceries like milk, eggs, rice, and peanut butter. It's not enough to live on, but it's the thing that lets a parent say yes to fruit this week instead of no.

In this Diving In episode, Justin walks you through what actually happened in four parts: what SNAP is and who leans on it, how the cuts ended up tucked inside Trump's 2025 budget law alongside big tax cuts for rich households, what the law actually changed, and what the data show now. The key detail: the new formula dings states for paying the wrong amount but not for wrongly turning eligible families away — a recipe for a slower, more suspicious system. By spring 2026, more than 4 million people had lost benefits, including an estimated 1.5 million children, even as nearly one in four adults still couldn't reliably afford enough food.

If your mum, your uncle, or your own household counts on this help, this is the shift that decides whether dinner is the thing that gives when the month runs long. Justin's takeaway: when politicians cut a program, don't just ask how much they saved — ask who lost what.

Why Trump’s New Tariff Is Bigger Than Canada | Diving In Jul 21, 2026

Show notes

Trump's new 50% tariffs on Canada bypass USMCA — here's what it really means for you.

President Trump just hit a limited set of Canadian goods with 50% tariffs, and he did it by dusting off Section 338 of the Tariff Act of 1930 — a law last used when Herbert Hoover was in the building. Justin Wolfers walks you through what actually happened, why it's stranger than it sounds, and why the direct cost to the U.S. is smaller than the message behind it.

Here's the twist: throughout the earlier trade wars, being compliant with the USMCA free trade agreement was your escape hatch — roughly 90% of Canadian goods came in duty-free. These new proclamations ignore that agreement entirely. Justin's quick-and-dirty math says the tariffs cover a bit more than $20 billion of imports, about 5% of what we buy from Canada — meaning maybe $50 to $150 a year on your household, plus higher prices from American firms that now face less competition. For Canada it's a real hit: close to 1% of GDP.

But the bigger story is confidence. If a signed trade deal only holds until the next presidential mood swing, it's not really a rule. Justin argues Canada is the test case — a warning to the roughly 60 countries facing new tariffs any week now: retaliate, and your trade deal may not save you.

Justin Answers Your Questions on Trump Accounts | The Professor Is In Jul 20, 2026

Show notes

In this latest episode of The Professor Is In, Justin answers listener questions and responds to comments from his latest episode dispelling the hype around Trump Accounts. Justin argues that Trump accounts are really two policies bundled together. There’s the attention-grabbing $1,000 payment for newborns, which has a genuine “kernel of genius” if the goal is to introduce families to saving, investing, and compound interest. But that piece is temporary. The larger, more durable part is a tax-advantaged wealth-transfer tool that primarily helps upper-middle-class families pass assets to their children.

Wolfers connects these accounts to other temporary Trump-era tax promises — on tips, overtime, and Social Security — and contrasts those short-lived populist gestures with more permanent tax cuts for the rich. The result, he argues, is a style of fiscal policy that looks pro-worker on the surface while delivering much larger long-run gains elsewhere.

Justin also explains why complexity is not just annoying — but economically harmful. When benefits are routed through a maze of tax rules, account types, and employer provisions, take-up falls. And the people most likely to miss out are often the families who can least afford to, making an already regressive system even more unequal.
