Very exciting to update this chart with the 2025 data!
Millennials at age 40 have about 60% more real net worth than Boomers did at age 40, and almost 100 percent more than Gen X
THE 2025 FED SCF DATA HAS FINALLY BEEN RELEASED!!!

Workers in their 30s are digitally literate but got to form their minds before doomscrolling was possible.
Awesome work here tracking AI usage in the US and UK by age and income, by @jburnmurdoch, @sarahoconnor_ for @FT
They find:
60%+ of top earners use AI daily vs. just 16% of lower earners.
Men outpace women
30-somethings with deep expertise lead adoption
Conclusion: AI is widening workplace inequality, not flattening it.

Why don’t we control deer and deer ticks while we are at it?
There is no good reason for mosquitoes to exist in wealthy countries today.
New technologies can get rid of the mosquito species that cause diseases like dengue, yellow fever, and malaria; and others can prevent them from carrying those diseases.

So why do mosquitoes still exist?
In a new article for Works in Progress, Maya Rosen explains how state incapacity and risk aversion led to over a decade of delays and billions of unnecessary bites in the United States.
Oxitec, for example, engineered an Aedes aegypti mosquito in such a way that its female offspring would die before adulthood. Through sustained releases, they showed they could reduce local mosquito populations by 80% or more, in field trials.
They sought approval from the USDA in 2010, which then passed it to the FDA, which passed it to the EPA. In 2020, the EPA allowed them to conduct limited field trials in the Florida Keys. Two years ago, their experimental permit expired, and they still need another review before it can be used routinely. Their proposed field trial in California was withdrawn after public opposition.
Another company, MosquitoMate, developed a technique involving Wolbachia, which also suppresses local mosquitoes. They then spent over fifteen years working through the system before finally receiving commercial registration nationwide in 2024.
It seems that, sometimes, the barrier to getting rid of diseases isn’t technology at all. It’s policy and political will.
New products shouldn’t get stuck in regulatory review for so long, especially if the delays are about basic questions like which agency has oversight over the product, rather than testing for safety.
Though some of those uncertainties were being addressed, the broader changes haven’t materialized. After Biden’s 2022 executive order, the agencies planned to update how their coordinated framework was implemented. But Trump rescinded the order last year.
Meanwhile, the EPA unit that reviews new mosquito control products is still a small office backlogged in reviewing a wide range of products.
Mosquitoes are a policy choice. We can get rid of them. Will we choose to?

What is a good paper to give undergraduates in a Labor Economics class?
Feel free to recommend your own work, or a classic paper, or something cool you saw

Interesting that the music business has almost recovered to its 2000s peak but it’s all being driven by live performances. Streaming is tiny compared to the physical medium it replaced.
Replying to @JosephPolitano
Can the arts business model survive AI? Perhaps the best guide is to look at how the arts survived past tech revolutions
Take music—internet piracy and then streaming killed the lucrative CD market, but musicians mostly saved their jobs by focusing much more on live concerts
Works every time. #teachecon
Econ teachers check out this new game by @MarketPowerYT at mapgdp.com/ I'm going to try it out on the projector for my next class. Students can guess GDP per capita based on pictures pulled from Google maps.
I thought we might have to stop scaling because of limits, but apparently marginalrevolution.com/margi…
