Study: The origin of the state was based on confiscation, and not on things like cities or growth. They investigate this by looking at early states, and what they have in common. And this common trait is grain, which can be stored or confiscated. Not on land productivity.

Just published in Journal of Public Economics: "Avoidance Responses to the Wealth Tax" By Mariona Mas-Montserrat, Jose Maria Durán-Cabré, & Alejandro Esteller Moré sciencedirect.com/science/articl… #econtwitter

When I was a kid, leukaemia was thought of as a death sentence – perceptions were still anchored to the pre-1980s times when it was. Today, 94% of kids survive it. Miraculous.

Ready for an interesting historical story with a somewhat surprising ending? Away we go! In 1975, a federal court ordered the desegregation of public schools in Jefferson County, KY. In order to equalize the share of minorities across schools, students were assigned to a

In 2010 SCOTUS allowed states to loosen gun laws. In those that did, many more kids have been killed. In the 9 states that didn’t and have the strictest laws, numbers have stayed the same or dropped. The leading cause of death for U.S. children is getting shot. It’s a choice.

Another great @carbonbrief.org explainer by Zeke Hausfather.bsky.social. TLDR? We emit aerosols that mask ~0.5°C of existing warming from GHGs. We have to stop unabated combustion of FF, a source of aerosols, to stop adding CO2. The solution space is very narrow carbonbrief.org/explainer-how-…
