More on Elizabeth Holmes and prison

The Free Press asked me to expand upon my views of this matter, here is one excerpt from the piece: Third, fewer women in prison does not have to mean less deterrence overall, as arguably we should concentrate more of our legal resources on deterring violent men. Note that if we can release enough women […] The post More on Elizabeth Holmes and prison appeared first on Marginal REVOLUTION. CommentsThis was a really bad article.

Do mass shootings in universities lead to permanent effects?

Using a stacked difference-in-differences design covering shootings between 1990 and 2025, I compare cohorts at affected universities before and after the shooting with cohorts at matched control universities. I find no detectable effects on time to degree, but undergraduates enrolled at the time of the shooting are 4.2% less likely to pursue further studies. Those […] The post Do mass shootings in universities lead to permanent effects? appeared first on Marginal REVOLUTION. CommentsI'm so h...

Saving for the machines

From Jesús Fernández-Villaverde: When machines can perform a growing share of tasks, growth depends on two margins: how the task structure affects the returns to accumulating machines, and how strongly capital accumulation responds to those returns. I argue that, in a standard task model, capital supply governs the size of the growth boom associated with automation, […] The post Saving for the machines appeared first on Marginal REVOLUTION.

The Causal Effect of Foreign Ideas on U.S. Innovation

Globalization is once again better than many people realize: We study the role of foreign ideas in U.S. innovation by constructing a directed “genealogy” of technologies from the full text of 13 million patents filed between 1887 and 2024. By tracing which earlier technologies appear in the founding patents of new ones, we recover a […] The post The Causal Effect of Foreign Ideas on U.S. Innovation appeared first on Marginal REVOLUTION.

One reason I do not love AI writing, or even AI-assisted writing

Of course I read to absorb the content, but I also am in a position to meet many authors, have contact with them, and spend time with them. So reading anything also is a potential option on those future connections. But when I am reading an AI piece, the value of that option comes pretty […] The post One reason I do not love AI writing, or even AI-assisted writing appeared first on Marginal REVOLUTION.

The California billionaire tax is very likely a net revenue loser

This paper examines the revenue and migration impact of the 2026 California Billionaire Tax Act, a one-time 5 percent tax on the worldwide net worth of individuals exceeding $1 billion. Using data from the Forbes Billionaire List, news reports detailing the residential real estate holdings of California billionaires, and public announcements of billionaire departures from […] The post The California billionaire tax is very likely a net revenue loser appeared first on Marginal REVOLUTION.

The net fiscal impact of immigration should include gains from trade

Immigration affects natives through both labor markets and public budgets, yet these channels are usually studied separately. We combine them in a general-equilibrium model with search-and-matching frictions, skill-specific progressive labor taxes, capital taxation and public goods, calibrated to 17 OECD countries over 2015-2019. The welfare effect on natives of a one-percentage-point increase in immigrant inflows […] The post The net fiscal impact of immigration should include gains from tra...

*This Beautiful Country*

The author is Edward Cutler and the subtitle is How Italy’s Nature Shaped its Culture and Civilisation. This is an excellent book on how “the Italy you know” has been shaped by its natural environment, such as its mountains, rivers, geology, and so on. Ever wondered why Sardinia is different? The book is good at […] The post This Beautiful Country appeared first on Marginal REVOLUTION.

*You Can See Everything* (no spoilers)

An excellent and also original movie, you all should see it. There are different interpretations, but I read it as a story between two autistic people, and the bond they have but also the great difficulties they have in understanding each other, because they are so very different. I am not saying that is what […] The post You Can See Everything (no spoilers) appeared first on Marginal REVOLUTION. CommentsIn reply to David R Henderson.

Our fascination with screens, demand curves slope downward installment #1637

What we find here is that the quality-adjusted screen time price index is down 39 per cent since 2000, but that change is overwhelmingly a function of improvements in quality, not declines in prices paid for devices, subscriptions and so on. So the steep rise in screen time over the past 20 years has led […] The post Our fascination with screens, demand curves slope downward installment #1637 appeared first on Marginal REVOLUTION.

India has more Restrictive Labor Law than Germany

In Premature Imitation and India’s Flailing State, Shruti Rajagopalan and I discuss how India has essentially all of the laws of a developed country but at much lower state capacity–this mismatch creates what we call premature imitation, with a host of negative consequences. What is even more amazing, however, is when a country like India […] The post India has more Restrictive Labor Law than Germany appeared first on Marginal REVOLUTION.
