Conversations with Tyler

Roman Mars has built one of podcasting's great empires out of noticing things everyone else walks past. His show, 99% Invisible, has racked up over 500 million downloads telling stories about the unnoticed design choices that quietly shape how cities and objects work, from speed bump psychology and flag design to the shape of a good street sign. His TED Talk on vexillology (the study of flags) is so influential that it has reportedly spurred 250 to 300 municipal flag redesigns across the country, including in Pocatello, Idaho, a city he once publicly called out for having the worst flag in America. Tyler asked questions about nearly every visual surface of modern life, and Mars's answers keep circling back to the same tension: beauty and efficiency are often at odds, and most of what looks ugly to us is just a compromise we haven't yet learned to love.
Tyler and Roman discuss street signs, why classic cars were so much more distinctive than today's SUVs, Waymos, New Jersey jughandles, yellow streetlights, lane-stripe colors, why Houston keeps growing despite its lack of charm, whether any post-war American suburb is actually beautiful, the Chrysler Building's rocky reception, brutalism done right and wrong, Central Park as an urban miracle, what Jane Jacobs got wrong, e-bike lanes, Tokyo's bike-free transit model, the placelessness of global coffee shops, why the iPhone looks boring now, the ugliest country he's visited, his love for Australia's polymer notes, his soft spot for the dollar's "locked in amber" weirdness, underground power lines, how to warn future civilizations about nuclear waste, why highway signs lie to you about speed limits, the principles of a great city flag, the Pocatello redesign saga, his own studio, why 99% Invisible works precisely because it's audio-only, the most unusual habit behind his long productive career, and more.

Liaquat Ahamed has spent years making central bankers into compelling characters. His 2009 book Lords of Finance won the Pulitzer Prize for its account of the bankers whose decisions helped cause the Great Depression; his new book, 1873: The Rothschilds, the First Great Depression, and the Making of the Modern World, tells a stranger story — a severe deflationary crisis that barely dented global growth but poisoned politics for a generation. Tyler pushes him hard on the central puzzle of those two books — why did one financial crisis derail the world, while another left growth almost untouched?
Tyler and Liaquat start with that puzzle before moving through Gladstone's startlingly self-interested bet on Egyptian bonds, Bismarck's role in destroying bimetallism and deflating the world economy for two decades, whether a global silver or symmetallic standard could have worked, Britain's fateful decision to re-peg the pound to gold in 1926, Hjalmar Schacht's transformation from the economist who stabilized Weimar's currency to opportunist collaborator with the Nazi regime, Montagu Norman's spiritualist beliefs, why the 1920s produced such a creative cultural moment, lessons from the IMF on Ireland's housing bubble and Pakistan's two dozen bailouts, what went wrong in the eurozone crisis, Britain's baffling modern stagnation, and finally to his own restless career and what he wants to write next.

Luis Garicano has one of the more unusual résumés in economics: trained at the University of Chicago Booth School under Gary Becker, Kevin Murphy, and Sherwin Rosen, he left academia for a stint as a member of the European Parliament before returning to research, now at the London School of Economics for a second time. His new book, Messy Jobs, co-authored with Jin Li and Yanhui Wu, argues that AI won't cause mass unemployment for a surprising reason: it will make jobs messier, not simpler, and messiness is precisely what AI struggles with.
Tyler and Luis start their conversation with Spain — housing, NIMBYism, and the productivity crisis; Spanish literature and why the Civil War still looms so large; and what Chicago taught Luis about party discipline in European politics. Then to the EU's unanimity problem, capital markets, and Denmark's flexicurity model; a round of overrated-versus-underrated on Rosalía, Penélope Cruz, and Sgt. Pepper's; and finally into Messy Jobs — why retraining programs fail, whether AI's leisure dividend has arrived, and whether Spain could ever achieve AI sovereignty.

Gita Gopinath has spent the last several years inside the room where the world's monetary plumbing gets fixed — or doesn't. As first deputy managing director of the IMF and, before that, the Fund's chief economist, she worked on sovereign debt restructuring, followed Argentina's disinflation up close, and built her academic reputation on ideas like dollar dominance and the dominant currency paradigm. Now back at Harvard launching a new Global Economics Lab, her conversation with Tyler ranges from why exchange rates don't adjust the way models predict, to what stablecoins really cost, to whether AI's growth dividend will show up on schedule.
Tyler and Gita discuss why trade balances are only weakly related to real exchange rates, before turning to Argentina, Milei's fiscal discipline, the peso, and dollarization. Then they discuss whether economists got the euro wrong; whether trade imbalances with China are really the problem; stablecoins, CBDCs, and the Treasury market; and whether AI will ease the debt burden, cause stagflation, or transform economics itself. Finally, they turn to her family's Kerala roots: why the state keeps electing communists, the relationship between matriarchy and social indicators, single-sex education, and what she's building next.

Annie Lowrey's new book, The Time Tax, argues that the most regressive levy in American life is the hours each of us must spend on hold, in waiting rooms, and filling out forms a competent state would have pre-filled — roughly fifty a year on average, and far more if you're poor. Tyler spends much of this conversation pressing the opposite case, asking whether that bureaucracy is quietly serving a useful purpose by rationing knee surgeries that don't work, deterring fraud, or screening for immigrants with gumption.
So Tyler and Annie hash it out over an hour, covering why TANF and other welfare programs are the worst offenders, the political economy of submerged benefits like the child tax credit, whether the postal service should be zeroed out over ten years the way Denmark did, whether the government should be nudging people out of rural areas, lessons from the COVID unemployment fraud, areas where the time tax is flat instead of regressive, which private sector time taxes are most onerous, whether AI agents will pay these taxes for us within five years, the logic of easy benefits plus randomized harsh audits, the case for less federalism, whether voting should be easier or harder, how the UBI studies changed her priors, where you can find the best moss in the world, her favorite example of Brutalist architecture, tattoos as permanent ephemera, Christianity's role in liberalism and the post-Christian right, how reporting beats tourism, the time tax of friendship, what she'll learn next, and more.
