A great example of why I don't trust synthetic controls; the estimates are simply misleadingly beautiful

🚨New NBER working paper alert 🚨

🤔2021–2024 was the worst U.S. inflation in four decades. The question: Did voters react to the rising prices, or to the shrinking paychecks?

😱We approached this paper with one major surprise: there is no official measure of inflation at the county level in the U.S.

🌟To study the relationship between inflation and electoral outcomes during, we first had to construct local inflation measures using county-level data on family budget costs and incomes.

The answer? -> Check it out! 👇

One person who was completely vindicated in time was Shiller with his AEA address on narrative economics.

I was there at the time, and thought: cool idea, but no way you can operationalize this.

LLMs have made it much easier to study narratives

Daron is still against AI in Science even though one of the best mathematicians Terence Tao says AI makes thought experiments and bold attempts less costly, which definitely lead to more general knowledge.

The labor market has been steadily tightening, albeit just a notch--and maybe in absolute terms it is still loose.

Unemployment rate stable/edging down while job openings stable/edging up.

Ratio of V/U has risen from a low of 0.87 in December to 1.03 in April.
