*Redefining Global Health in the 21st Century*
Tyler Cowen
While donor-driven programs undoubtedly saved millions of lives, they also created unintended distortions in national health priorities. Many governments in sub-Saharan Africa and parts of Asia actually scaled back domestic health investments, as donor program filled key gaps in HIV/AIDS, maternal and child health, and infectious disease control. In some cases, domestic health budgets shrank in real terms, even as external funding increased. This phenomenon, often referred to as “fiscal substitution,” led to national health systems that were heavily donor-dependent, externally managed, and vulnerable to funding shocks. Notably, this reliance emerged despite countries pledged to allocate at least 15% of their national budgets to health. More than two decades later, only a handful has met this target.That is from the new and useful book by Michael John Alastair Reid and Eric Paul Goosby. But $150 for a not so thick volume!? If the authors believe in aid, as they should, perhaps they could consider giving this book away for free rather than turning it over to Elsevier…?The post *Redefining Global Health in the 21st Century* appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesWhat should I ask Jared Diamond?The AEA presidential election*Liberal Worlds: James Bryce and the Democratic Intellect*

Immigration and Macroeconomic Outcomes in OECD Countries
Tyler Cowen
OECD countries experienced declining native population growth and rising net immigration over 1990-2024. We compile a new dataset of net immigration rates to OECD countries from all origins and show that most of the increase came from non-OECD countries and was predominantly high-skilled. Push factors, network effects, and policy indices explain little of the large cross-country heterogeneity in immigration dynamics; unexpected shocks and surges were common. Using local projections and several sources of identifying variation, we then estimate the relationship between immigration and growth in GDP per capita, labor productivity, capital investment, and total factor productivity (TFP). Immigration from non-OECD countries was a significant predictor of GDP per worker growth, primarily through higher investment. High-skilled immigration, in particular, was associated with stronger human capital accumulation, faster TFP growth, and greater capital deepening. Native population growth, by contrast, had no or weakly negative effects on GDP per capita and productivity. These results are consistent with a large literature documenting the positive productivity and growth effects of immigration, especially high-skilled immigration.That is from a new NBER working paper from Gaetano Basso, Mitali R. Mathur & Giovanni Peri.

Rothko show in Florence
Tyler Cowen
In Museo San Marco there is an ancillary exhibit, placing some smaller, lighter colored Rothkos next to their Fra Angelico frescoes. Those rooms bowled me over, as for one thing they show how much Rothko was a religious painter at heart.I also was struck by the high proportion of Chinese visitors at this show, even though they are not especially numerous in Florence right now.The main Rothko show, at Palazzo Strozzi, had an opening room showing Rothkos tied to Renaissance (!) art, mostly with works from early Rothko. The rest of the exhibit had perfect lighting and was the best Rothko display I have seen.Ken Griffin has very good taste in Rothko. One of his works is here.Visiting Florence in August is less unbearable than I was expecting. So many other places have become crowded that the situation here does not phase me. Plus the heat is keeping many away? At dinnertime, there is no crush to get into the restaurants.Moving on shortly, just here for one day!The post Rothko show in Florence appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesThe Rug Belt Atlas and QuizMy excellent Conversation with Andrew Graham-DixonMarkets in everything?

Mexico (Taiwan) fact of the day
Tyler Cowen
Mexico has quietly become a cornerstone of the AI boom, providing 40 per cent of US imports this year of the computer servers that are widely used in the data centres powering artificial intelligence.Taiwanese manufacturers are rapidly expanding factories in Mexico to assemble servers, which are now the country’s top US export, overtaking autos that dominated its trade for decades.Mexico is the second-largest provider of enterprise servers to the US so far this year, with sales reaching $46.9bn, behind Taiwan, which sold $53.5bn, though Mexico became the largest on a monthly basis in May.The phenomenon is helping prop up Mexico’s limp economy, pushing the country’s exports to record levels. Servers and related hardware made up almost one-fifth of the $317bn of goods Mexico exported between January and May, more than double the same period a year earlier. Taiwan, in turn, is now Mexico’s third-largest trading partner, up from eighth place in 2022. Taiwanese companies have spent more than $1.6bn since 2020 on Mexican factories that offer geographic proximity and tariff-free access to US tech giants spending hundreds of billions on data centres.“Mexico is of tremendous importance to the way this new AI-powered economy is working,” said Jesse Rogers, head of Latin America economics at Moody’s Analytics. “It is really a new frontier of collaboration and even dependency on the Mexican economy when it comes to AI servers.”Here is more from Christine Murray and Alan Smith at the FT.The post Mexico (Taiwan) fact of the day appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesMore math breakthroughs from GPT modelsThe wisdom of Eli DouradoReforms to the PhD?

*Rome’s Age of Revolution*
Tyler Cowen
The author is Tim Whitmarsh and the subtitle is Augustus, Empire and the Making of Christianity. This is the most important book on the history of Christianity I have read in a long time, and it is also an important work in Roman history. Yet also fun and extremely readable. Excerpt:The story I have told so far has emphasised the fit between Christianity and the Greek world of the early Roman Empire; I have given relatively little space to conflict. That has been quite deliberate. One of the commonest misconceptions about the early Roman Empire is that it was a time of ceaseless and inevitable suppression of virtuous Christians by a brutal governmental machine. This is a myth that has roots in antiquity itself, and has been pumped systematically into western popular culture since the nineteenth centuury. It is a remarkably durable myth, because it is both emotionally seductive and ideologically powerful. The idea that virtuous Christians were engaged in endless conflict with the Roman state makes for great narrative. But the reality is more banal: most Christians were fully integrated into Roman society, and no more or less harassed than anyone else…My argument has been, rather, that Christianity could not have come into being in anything like the form we know it without the revolutionary impact of Augustus’ political reforms. It was this seismic change that fundamentally transformed Mediterranean thought…The most dramatic effect of the Augustan swirl was Christianity itself: a breakaway Judaean sect led by brilliant entrepreneurs who understood the opportunities offered by the new political dispensation, and rapidly reshaped their ideas to suit new audiences.Definitely recommended, and not only to Christians and Romans.The post *Rome’s Age of Revolution* appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesWhat should I ask Jared Diamond?*Liberal Worlds: James Bryce and the Democratic Intellect*Odysseus notes

On infinite ethics
Tyler Cowen
Infinite numbers have long troubled utilitarian ethicists: if the universe is boundless, then there is infinite positive utility and infinite negative utility, and we can’t even define our current state, let alone affect it. Oxford philosopher Toby Ord proposes a solution: use hyperreal numbers, a mathematical construct in which infinite sums behave more like finite ones (for example, the sum of infinitely many twos is twice as big as the sum of infinitely many ones). As with so many philosophical ideas, this solves some existing problems while creating some new ones (pinpointing some hyperreals requires choosing something called an “ultrafilter”, but this choice is underdetermined). Still, Elias Schmied calls this a real philosophical advance, of the sort which comes along only rarely and makes genuine headway into a previously-hopeless-seeming problem. I’m just surprised there’s a way of thinking about infinities under which they behave logically. Why didn’t we start with this one, instead of being told that infinity + infinity = infinity and we should just accept it? Claude tries to answer my questions.That is from Scott Alexander (many more links at the link, many on AI safety).The post On infinite ethics appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media MediaRelated StoriesCould our preoccupation with mental health be part of the problem?Odysseus notesThe Decision, the sequel

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. List, Matthias Rodemeier, Sutanuka Roy & Gregory K.

Victor Niederhoffer, RIP
Tyler Cowen
In addition to his well-known public roles, he worked very hard to help and befriend me when I was younger. Here are the Google searches for Victor. Less well known about Victor is that he had one of the world’s best collections of private letters. He also once gave me a very nice small painting by Jack Savitzky.The post Victor Niederhoffer, RIP appeared first on Marginal REVOLUTION.MediaMedia Media Media Media Media Media Media
