The Human Action Podcast

This week, Bob explains Cantillon effects: the insight that new money doesn't raise all prices equally or simultaneously, but flows through the economy in a sequence that benefits early recipients at the expense of everyone else. Then, he shows why this phenomenon is the foundation on which the entire Austrian theory of the business cycle is built.Related:Richard Cantillon, An Essay on Economic Theory: Mises.org/HAP544aThe Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.

Bob untangles two arguments that even Austrian economists sometimes conflate: Mises' calculation problem and Hayek's knowledge problem. Then, he explains why the distinction matters, especially in light of recent claims that AI and modern computing could finally make central planning viable.Related:Bob's Article, "Socialism: The Calculation Problem Is Not the Knowledge Problem": Mises.org/HAP543aThe Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.

Bob lays out California’s proposed 5% wealth tax on billionaires, using it to explain why taxes on wealth are especially destructive, how different tax structures change incentives, and what recent migration data says about people voting with their feet.Related:Data on 2020–2024 State-to-State Migration: Mises.org/HAP538a"Where Americans Choose to Move and Where They Leave": Mises.org/HAP538bPoliticians don’t build prosperity.

Bob applies Mises’ taxonomy of money and the regression theorem to Bitcoin, asking whether it should be classified as commodity or fiat money and whether Austrian theory really rules out Bitcoin ever becoming money.Related:Mises's The Theory of Money and Credit: Mises.org/HAP536aBob's Study Guide to The Theory of Money and Credit: Mises.org/HAP536bBob's Primer on Bitcoin: Mises.org/HAP536cPoliticians don’t build prosperity.

Bob responds to James Rickards’ recent tweet on record U.S. gold exports driving an improved trade balance, walking through the official data on non-monetary gold, Trump-era tariff uncertainty, and the broader question of what chronic trade deficits really mean in a post-gold-standard world. Related:The Charts Used in this Episode: Mises.org/HAP535aBob's Recent Talk on Trade Deficits: Mises.org/HAP535bBob's Econlib Article on Oil Prices: Mises.org/HAP535cPoliticians don’t build prosperity.

Bob revisits Böhm-Bawerk’s critique of the exploitation theory of interest to answer modern claims that billionaires like Elon Musk must have “stolen” their wealth from workers who supposedly create 100 percent of a firm’s value.Related:Böhm-Bawerk’s Critique of the Exploitation Theory of Interest: Mises.org/HAP534aBöhm-Bawerk’s Karl Marx and the Close of His System: Mises.org/HAP534bPoliticians don’t build prosperity.

Bob talks with Dr. Peter Klein about the recent U.S. operation in Venezuela and the social-media backlash against “international law,” using it as a springboard to clarify what law is, how it can exist without a world government, and why Austrians care about polycentric legal orders.The Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.

This week, Bob talks with macroeconomist Roger Farmer—who places himself “between Keynes and Hayek”—about how twentieth-century macroeconomics evolved. They discuss how overlapping generations and search theory change the story on unemployment and asset prices, and where Professor Farmer thinks both neoclassicals and MMT advocates go wrong. Farmer contrasts the old “rocking horse” vision of the economy with his preferred “windy boat” metaphor, where the economy can drift for long periods, and variables like unemployment behave more like random walks than quick returns to a single steady state.Related:Professor Farmer's Article, "How New Keynesian Economics Betrays Keynes": Mises.org/HAP532aThe Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.

Bob uses three recent controversies–Richard Murphy’s “Christmas all year” claim, Elon Musk’s net worth, and Ron DeSantis on the Great Depression–to clear up common economic fallacies about work, wealth, and wartime spending.The Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.

Bob uses clips from his recent interview with Eric Weinstein to explain why Weinstein thinks gauge theory can fix how economists measure the cost of living, unify competing price indices, and handle changing preferences over time, and why Austrians shouldn’t dismiss him as a crank. He summarizes Eric’s claim that standard mathematical economics relies on the simplest kind of derivative, explaining how much of modern economic modeling is using the wrong math.Related: Bob's Interview with Eric Weinstein on the InFi Podcast: Mises.org/HAP530aThe Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.

This week, Bob walks through two related debates: Hoppe’s criticism of Argentina's President Milei for not immediately closing Argentina’s central bank, and the follow-up exchange between Guido Hülsmann and Philipp Bagus on Mises.org over dollarization and the peso. Along the way, he reviews Mises’s distinctions among commodity, credit, and fiat money, the concepts of money substitutes and fiduciary media, and the interesting structure of Argentina’s short-term central bank debtGuido Hülsmann and Philipp Bagus' Debate on Mises.org: Mises.org/HAP529aThe Human Action Podcast Episode with Nicolás Cachanosky: Mises.org/HAP529bBob's Study Guide to The Theory of Money and Credit: Mises.org/HAP529cThe Mises Institute is giving away 100,000 copies of Hayek for the 21st Century.
