How does the market regard stablecoins?
Tyler Cowen

We study the demand for safety and liquidity in the crypto ecosystem. We do so under a framework in which a representative investor allocates liquidity across stablecoin deposits in lending pools and traditional safe assets (e.g., MMF shares). Our model delivers three main predictions: (i) the stablecoin deposit premium co-moves with the Treasury premium when investors value the safety and liquidity services of stablecoins; (ii) increases in Treasury supply reduce the stablecoin deposit premium; and (iii) drops in the perceived safety and liquidity of stablecoin deposits (e.g., due to de-pegs or hacker attacks) reduce their premium. Using granular data from hundreds of DeFi pools spanning multiple protocols, tokens, and blockchains, we find evidence supporting these predictions. Investors treat stablecoin deposits as money-like instruments that are borderless and permissionless, yet as fragile as other forms of privately produced safe assets.That is from a new NBER working paper by Murillo Campello, Angela Gallo, Lira Mota & Tammaro Terracciano.The post How does the market regard stablecoins? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media Media

The economics of H-1B immigration
Tyler Cowen

We study the effects of H-1B immigration on U.S. industries that employ H-1B workers and their trading partners. Using a novel cross-industry design and the 1999–2003 expansion of the H-1B visa cap for identification, we find that H-1B exposure raised incomes for natives and pre-existing immigrants, with gains concentrated in non-STEM occupations. Income gains propagate forward through supply chains to downstream industries but not backward to upstream industries, consistent with a productivity shock rather than a labor supply shock. We find no direct effect on patenting, suggesting that productivity gains arise from better task execution rather than patentable invention.That is from a new NBER working paper by Ran Abramitzky, Leah Platt Boustan, Ahmet Gulek & Jens Hainmueller.The post The economics of H-1B immigration appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesImmigration and Macroeconomic Outcomes in OECD CountriesThe Apples and Oranges TribunalOn the Acemoglu-Autor et.al. fertility result

Estimating the Economic Value of Zoning Reform
Tyler Cowen

We estimate the economic value of zoning reform in São Paulo, which altered maximum permitted construction along transportation corridors. Developers increased filings for multifamily construction in blocks affected by the reform, leading to more housing supply and lower housing prices in neighborhoods that allow more densification. Our equilibrium model of housing markets estimates an aggregate 1.6 percent increase in housing stock and a 0.4 percent reduction in prices, resulting in large housing wealth transfers from current to future homeowners. The reform produced welfare gains of 0.65 percent of city GDP, mostly due to developer profits and consumer gains from the newly built environment.That is from the AEA policy journal, by Santosh Anagol, Fernando Ferreira, and Jonah Rexer.The post Estimating the Economic Value of Zoning Reform appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesThe economics of H-1B immigrationImmigration and Macroeconomic Outcomes in OECD CountriesThe Apples and Oranges Tribunal

The Value of Behavioral Policies
Tyler Cowen

Behavioral interventions have become central to modern public policy, but their empirical promise remains contested because estimated treatment effects often appear small. We argue that a policy response is economically meaningful only relative to the response generated by alternative policies. We assemble more than 1,200 estimates from over 600 studies comparing “nudges” and traditional price interventions in the markets for cigarettes, alcohol, influenza vaccination, electricity, and residential water. Translating nudge effects into equivalent price changes, we find that behavioral interventions often correspond to enormous fiscal interventions, from an 11% tax on electricity to a 100% subsidy on influenza vaccinations. Nudges are also more cost-effective than price instruments in all markets, but cost-effectiveness does not predict the welfare ranking of policies. Using a behavioral extension of the Marginal Value of Public Funds, we show that nudges have high welfare returns at the margin, while price instruments often generate larger total surplus at scale.That is from a new NBER working paper by John A.

Is this why China finds it so hard to inflate producer prices?
Tyler Cowen

This paper investigates why China’s recurrent credit expansions have coincided with persistently weak inflation. We argue that this pattern reflects the country’s production-oriented monetary regime. At the aggregate level, faster monetary-financial expansion temporarily raises PPI inflation but depresses it over longer horizons. At the sectoral level, liability growth among listed industrial firms is followed by weaker producer prices, lower profitability, higher leverage, rising inventories, and reduced capacity utilization. We also find asymmetric supply-chain transmission: downstream liability growth raises upstream PPI inflation, while upstream liability growth does not generate a corresponding downstream price response. These findings indicate that credit expansion in China tends to sustain production and balance sheets rather than stimulate final demand. As a result, monetary policy operates less as a conventional tool for demand management and durable reflation, and more as a mechanism for preserving production capacity and supporting growth.That is from a new paper by Jeffery (Jinfan) Chang & Wei Xiong.  I have to say I understand the result but not exactly the mechanism.  I am reminded of Milton Friedman’s dictum not to focus too much on the first-order effects of an increase in money supply.The post Is this why China finds it so hard to inflate producer prices? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesThe Value of Behavioral PoliciesEstimating the Economic Value of Zoning ReformThe economics of H-1B immigration

Dominant Assurance Contract aka Refund Bonus Explainer
Alex Tabarrok

I created the dominant assurance contract aka the refund bonus mechanism in 1998–it’s a mechanism capable of producing some types of public goods privately–in recent years working with Tim Cason and Robertas Zubrickas I’ve put refund bonuses to the test in lab experiments and they work! I’ve written an accessible Refund Bonus Explainer that covers this body of work. Here’s one bit:The dike is a public good. Once it stands, it protects everyone nearby, and a neighbor who contributed nothing cannot easily be excluded. That property is what makes it hard to finance.Paul Samuelson gave this category its modern formulation in 1954, and he drew a pessimistic conclusion from it. Each person does better by understating what the good is worth to him, so it is, in Samuelson’s words, “in the selfish interest of each person to give false signals, to pretend to have less interest in a given collective consumption activity than he really has.” From this he concluded that “no decentralized pricing system can serve to determine optimally these levels of collective consumption.” Public goods, on this view, are what governments are for. Refund bonuses are a challenge to that conclusion.Read the whole thing and here is my Rent Control Explainer.The post Dominant Assurance Contract aka Refund Bonus Explainer appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media Media

Who Pays for Unions?
Tyler Cowen

If unions raise worker wages, who pays? We provide a comprehensive assessment of firm responses to increased unionization, using changes in the tax deductibility of union dues in Norway as a quasi-exogenous source of variation in firm-level union density. In the average private sector firm, higher union density raises labor costs and leads firms to contract employment and production, lowering profits without increasing the labor share. The incidence is shared: consumers bear part of the cost through higher prices, shareholders through lower profits, and the remainder is offset by productivity improvements. The total wage bill falls, with losses concentrated among less-attached “outsider” workers. Firm responses vary systematically by the degree of market competition. In manufacturing, where firms operate in less competitive product and labor markets, the response is reversed: the average firm expands employment and production, reduces labor markdowns, and does not experience profit declines. Instead, higher labor costs are largely passed on to consumers through higher prices, with the remainder offset by productivity gains. Workers benefit as both wages and employment rise. These patterns suggest that unions can offset employer monopsony power and that firm responses–and therefore who ultimately bears the cost-depend importantly on market structure. Overall, unionization in this setting primarily redistributes from consumers rather than shareholders and has effects that differ sharply across firms, including a reallocation toward larger and more productive firms. We rationalize these patterns using a partial-equilibrium model of union bargaining with product- and labor-market power.That is forthcoming in the QJE by Samuel Dodini, Anna Stansbury, and Alexander Willén.The post Who Pays for Unions? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesThe Value of Behavioral PoliciesEstimating the Economic Value of Zoning ReformThe economics of H-1B immigration

Will U.S. cities face a knock-on fiscal crisis from the feds?
Tyler Cowen

Federal money flows to cities in three flavors: direct transfers, indirect transfers, and what we call fiscal dark matter. Direct transfers are exactly what they sound like — money sent directly from the federal government to various localities. These include funds disbursed through programs like the Community Development Block Grant (CDBG), which supports things like public infrastructure and neighborhood services.3 In 2022, direct transfers like the CDBG totaled $146.3 billion.4 That’s significant, but actually the smallest of the three categories.Less visible are the indirect transfers. These monies are initially awarded to state governments, which then allocate funds to municipal-level programs and services in accordance with state prerogatives. The cleanest example is probably K-12 education, which receives federal Title I dollars to pay for teachers and programs, but federal highway dollars work essentially the same way. All told, in 2022, the federal government handed down $1.1 trillion to state governments. That amounted to 36% of overall state revenue for that year and, depending on the individual state, ranged from roughly 22% to 50% of state revenue. How much of that ultimately flowed down to cities is hard to say, which is itself a problem: it’s difficult to even establish how exposed local governments are to a pullback in federal support of state budgets.The third category – our fiscal dark matter – is all the federal money spent into local communities that never shows up in a local budget. This includes housing subsidies like the Low-Income Housing Tax Credit (LIHTC) and Section 8. It also includes food support programs like SNAP and even some direct funding for local food banks.Rightfully or not, when the flow of federal money in this category starts to dry up, the resulting problems will fall squarely on the mayor’s desk. After all, the median voter is never going to see increasing numbers of homeless encampments and think to blame the head of HUD.Here is the full piece by Jeff Fong.The post Will U.S. cities face a knock-on fiscal crisis from the feds? appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesWho Pays for Unions?Is this why China finds it so hard to inflate producer prices?The Value of Behavioral Policies

The Binmen of Birmingham
Alex Tabarrok

I was on the British CapX Podcast talking about the Equality Act, riffing off my two posts Equality Act 2010 and The Apples and Oranges Tribunal. One thing I discussed in the podcast which I haven’t blogged on is the amazing Birmingham dustbin dispute.In 2010 an employment tribunal ruled that Birmingham City Council had discriminated against thousands of female workers — cooks, cleaners, care assistants, caretakers — who were denied bonuses paid to the mostly male binmen, gardeners, and gravediggers. Why were the binmen given bonuses? Well, refuse collection is filthy, heavy, outdoor work and not many people want to be gravediggers. Thus, these jobs command a premium for exactly the reason Adam Smith gave in 1776 — compensating differentials. Or was it sexism? Well, note first that there is nothing stopping women from becoming “binpersons” and indeed there are female binpersons and they earn the same bonuses as their male counterparts (just as with the Next case). Moreover, we can test the sexism versus compensating differentials theory. Let’s see what happened.Here’s the problem, which contributed to Birmingham going bankrupt in 2023. The council employs roughly 400 binmen and something like 6,000 women in comparable graded roles. Every extra pound paid to a binman therefore implied about fifteen pounds owed to the cooks and cleaners. The council simply didn’t have the money to pay everyone binman wages so they cut the binmen’s wages. But the market wage for collecting rubbish is what it is, so when Birmingham finally deleted the premium in January 2025, the binmen went on strike — and they are still on strike, nearly eighteen months later. The rubbish piled up, 17,000 tonnes of it, and the city declared a major incident.Here’s the most amazing part. The council hired an outside contractor to take over its rubbish collection and it now pays roughly triple its pre-strike outsourcing bill–more than it was paying its own employees. So much for sexism. Apparently the premium wasn’t a favor to men; it was the price of the job. If you want your rubbish picked up and your graves dug, you must pay the market wage. This was pure regulatory arbitrage, of course. Because the new binmen were contractors they legally had a different employer than the Council’s female caregivers and the Act’s comparator rules stop at the employer’s nexus.The government mandarins, of course, want to close the “loophole” adding yet another bureaucratic requirement to push the equal pay madness up the supply chain.

My excellent Conversation with Julia Ioffe
Tyler Cowen

Here is the audio, video, and transcript.  Here is from the episode summary:Julia joined Tyler to discuss why so many of Russia’s great constructivist painters were women, why the tsarist government established women’s medical courses in 1872, changing attitudes towards abortion and birth control in the 20th century, why the Soviet regime turned prudish, how Khrushchev’s plan to “replace the dead” institutionalized single motherhood, Russian superwomen, why Jewish men were a prized commodity amid rampant antisemitism, the cultural significance of flowers, why a few Russian names still dominate, why Russian women think Western feminists have their priorities backwards, how gender attitudes and autocracy feed into each other, three underrated Russian novels, what she wants to write about next, and more.Excerpt:COWEN: I’m sure you’ve noticed that quite a few American men will marry Russian or Soviet women, but not so many American women want to marry Russian or Soviet men. It’s a kind of market test, right? Why exactly are the men so bad? Why are they such louts? Maybe that’s a rude way to put it, but surely in one’s mind, one asks that question, right?IOFFE: It’s a question that a lot of us who were living in Moscow in the late aughts and the teens were asking that all the time. I remember a friend of mine, a male Western TV correspondent, saying, “The women are so gorgeous here, but the men are so ugly and unfashionable.” He had lived all over the place and worked all over the place, and he said, “I’ve never seen such disparity,” and it was true.The women like me, Western women who were living and working in Moscow at the time, said, “We’ll just wait till we get home.” I think it’s because of what I talked about before, or what you and I talked about before, which is that so many men were killed in the first half of the 20th century, and so few demands were placed on them because they were seen as an endangered species, in general. They were a resource to be fought over and protected.In 1968, when the West was undergoing a sexual revolution, and women were fighting for more rights, more equality, the Soviets were talking about saving the men, protecting the men, and saying, “We’ve done enough for the women, but our men die young.” That’s after a lifetime of alcohol abuse, smoking, being largely irrelevant in the home, and obviously politically, because it’s a totalitarian system, so let’s work on protecting them.Soviet men, and then Russian men, became these coddled, spoiled children essentially, where on one hand, so little was asked of them that it’s the bigotry of low expectations. So little was asked of them, and very little was expected of them, and they rose to meet those very low expectations.On top of that, the idea of what made a man a manly man in Russia is he’s physically strong, but he dies a young death, or he dies an early death. He drinks a lot, he smokes a lot, he’s reckless, he’s careless, and takes a lot of risk, and that usually means an early death. If you have fewer men to begin with, and as a Russian woman, you see them dying early, and you’re fighting over them, what is the impetus for men to take care of themselves, to act better, be better, if there’s always going to be a beautiful, super competent woman to take him if you don’t want him?COWEN: These points you’re raising, historically, do you feel it’s been quite different for Soviet and Russian Jews or the same?IOFFE: I think it’s a little bit different. The caveat is, and I hate that I have to say this, Jews are people too, and subject to the same social forces that everybody else is, but culturally, Soviet Jews were more educated as a rule, more urban, and culturally came from a very family-centric tradition. Russian women, actually, for all the intense antisemitism in the Soviet Union, in Russia, Jewish men were actually a prized commodity for Russian women.COWEN: With ethnic Russian women?IOFFE: Yes. Ethnic Ukrainian women, you name it…

AI and Marginal Revolutions in Wastewater Treatment
Alex Tabarrok

An interesting paper from French economists, including recent Nobelist Philippe Aghion, looks at the savings from a predictive machine-learning model applied to wastewater treatment:This paper studies the environmental effects of a specialised AI aeration-control system deployed across French wastewater treatment plants operated by a global leader in water supply services. Exploiting quasi-experimental variation in both the timing of adoption and outages, we estimate the causal impact of AI on electricity use, carbon emissions, and energy expenditures. We find that full-time AI control reduces plants’ electricity consumption and carbon emissions by 5.4% and 6% respectively, and energy expenditures by 8.2%, resulting in negative abatement costs, while also improving water effluent quality. The additional electricity demand generated by AI models represents less than 1% of these savings. Beyond these effects, AI-equipped plants prove more resilient to high operational stress during extreme meteorological events and chemical pollutant peaks. They also improve load management by reallocating electricity consumption from peak to off-peak hours. Finally, we use the DICE model to assess the aggregate implications of our findings
in three diffusion scenarios. We find substantial global welfare gains from the CO2 reductions associated with this industrial AI use case.One annoyance: The authors frame the paper as a contrast to worries about AI’s energy use and environmental impact. But those objections are almost entirely innumerate and pretextual and casting the paper as a rebuttal lends them more credibility than they deserve.One note: Don’t misread the “less than 1%” line as being in the same units as the 5.4%, 6%, and 8.2% figures above it — it isn’t a comparable percentage-point offset. It means the AI system’s own electricity draw is a rounding error next to the savings it generates.More generally, the effect of AI will be through many, many improvements of this nature.The post AI and Marginal Revolutions in Wastewater Treatment appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesSolve for the (Refine) equilibriumThe Binmen of BirminghamWill U.S. cities face a knock-on fiscal crisis from the feds?

The Queen song ’39
Tyler Cowen

I only recently learned what it is really about, namely very rapid travel into space and time dilation mattering for the return voyage.I had never before listened carefully to the lyrics.  I heard the “’39” reference at the beginning, the mention of volunteeers sailing away, and the general nostalgic British music hall mood to the piece, and assumed it concerned the Second World War.  But no, the volunteers sailing away are going to the stars, and their eventual return to the Earth will be for them a sad and tragic event, as everything they had known will be gone.  You can listen to the song here.Here is one of the most direct excerpts:In the year of ’39 came a ship in from the blue
The volunteers came home that day
And they bring good news of a world so newly born
Though their hearts so heavily weigh
For the Earth is old and grey, little darling, we’ll away

What I’ve been reading
Tyler Cowen

1. Mike Jay, Wireheads: An Unnatural History of Technology in the Brain.  Much of this story is told through the lens of the accompanying science fiction and non-neuro trends in other parts of science.  An excellent book, substantive on every page, and it will make you want to read some of the works he cites.2. Vasily Grossman, From the Front Line, Stalingrad-Treblinka-Berlin 1941-1945.  Self-recommending, the best third of this volume is just stunningly good.  You do not have to read the whole thing, as there is some degree of repetition.3. Forough Farrokhzad, Let Us Believe in the Beginning of the Cold Season.  She died in a car crash in 1967 at the age of thirty-three, but it turns out she was an amazing poet.  I usually do not enjoy poetry in translation, but this is so fiery and full of passion that I am happy to recommend it.  Surely in the original Farsi it is better (and quite different?) yet.4. André Breton, Nadja.  It is short, and fun enough to read.  But one learns most books from the past are not masterpieces, and that surrealism as a movement — most of all in painting — was more important than the literary outputs of surrealism.  Nadja, to me, sounds like a drag.  Which is fine.  But.  What does Breton really think he is immortalizing here?  At the end he writes “Beauty will be CONVULSIVE or not at all.”  I do appreciate Breton for his understanding of Mexico, and for his cultivation of Haitian art.5. Emma Southon, Servus: How Slavery Made the Roman Empire.  A very good and aggressively readable book about how terrible slavery was in the Roman Empire.  A useful corrective to other sources as well.  While my general view is that interpretative disputes over antiquity are difficult to resolve, I find her interpretations more intuitive and more convincing than the other side of the debate.The post What I’ve been reading appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesMy excellent Conversation with Julia Ioffe*Rome’s Age of Revolution**Redefining Global Health in the 21st Century*

*Restoring Childhood: How to Set Kids Free in the Age of Anxiety*
Tyler Cowen

That is the new book by Peter Gray, and it is very much a whole philosophy of child-rearing and also antidote to the current panic over social media. Excerpt:In preparation for this chapter, I spent weeks poring over the research literature pretaining to smartphones, social media, and teen mental health.  It is clear to me that there is something close to a consensus among scientists most immersed in this research, which includes the following three conclusions: (1) Extensive research refutes the theory that effects of smartphones and social media account for a meaningful portion of the decline in teen mental health in the years following 2010.  (2) Smartphones and social media can have both beneficial and harmful effects on teens’ mental health, which tend to cancel out when averaging.  (3) Future research should focus on understanding better the ways teens use these tools and how to help them maximize the benefits and minimize the harm.Note that teen suffering also hit a peak around 1990 by many measures, yet that cannot have been caused by phones or social media.  And European teen suicide rates were falling just as those in the United States were rising.  This evidence is considered in further detail of course.Recommended, it is both easy to read and substantive.The post *Restoring Childhood: How to Set Kids Free in the Age of Anxiety* appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesWhat I’ve been readingMy excellent Conversation with Julia IoffeSolve for the (Refine) equilibrium
