This is such a bizarre talking point; I've thankfully never had to use most of the types of insurance that I have for me and my family

This is a good excuse to share my WSJ letter to the editor explaining that "not filing a claim doesn’t mean you didn’t need insurance" www.wsj.com/opinion/the-...

An interesting issue in global capital markets is that a lot of EM sovereign borrowing is (again) happening in loans rather than sovereign bonds, thanks to China. What does this mean?

Ben Bernanke, revisiting earlier work, shows how much financial distress of borrowers, not just lenders, significantly depressed credit flows, spending and economic activity in the Great Depression -- and politicians saw normalization of credit flows as top priority. www.aeaweb.org/articles?id=...

The EU is running a tight race to the bottom with the US for fiscal insolvency. Here is a great summary of the situation, and how much fiscal adjustment is required by country:

How bad is the US fiscal situation? Could it be sustainable? Is there anyway out besides a crisis and Great Depression II?

👀 Scoop: IRS Direct File, the free government-backed program that let you file your taxes for free, is dead.

IRS wrote to state tax agencies saying it would not be operational this coming tax season, per records I've obtained.

IRS Direct File: 2023-2025.

(Story from when the pilot launched.)
IRS tests free e-filing system that could compete with tax-prep giants
The tax agency has quietly built its own prototype system for filing tax returns digitally and free of charge, according to current and former officials.

Still corruptly running political ads on our Treasury department webpage
November 4, 2025 at 4:10 PM
This is corruption. Bessent should be embarrassed to use a U.S. government webpage for political advertising.
I went to the Treasury website to read a recent speech and was greeted with this…the US govt has become an embarrassment

Solution train LLMs on economists!
There are many better reasons to avoid LLMs, but I think part why I viscerally don't like them is that their obsequious fawning gives me the heebie-jeebies. Creepy as all fuck
I do wonder what will happen after years of heavy AI users receive every statement prefixed with clappy-toddler-encouragement. I find this stuff extremely annoying/inefficient/insincere, but presumably it's being selected strongly in the reinforcement learning from human feedback...

This is part of how we used to build things quickly
This Day in Labor History: October 26, 1825. The Erie Canal opened, eight years after construction commenced. This engineering marvel would have enormous impacts on the future of American work, including spurring ever-greater industrialization. It also killed over 1,000 workers building it!

According to the Wayback Machine, the Reagan Library's video of his address "on free and fair trade" had just 274 views last December.

It had 232k views at the time of the last snapshot, in July.

Today it's about to cross half a million.

Meant to post this sooner. Inflation hit 3% Y/Y. Not as hot as could have been but still warm. Troubling that 40% of the data are now imputed due to staffing shortages prior to shutdown.

Calling social scientists! First sentence & last sentence of this quote are a very confident claim and a very confident forecast. Is there social scientific evidence or is this Supreme BS?
Every now and then I go back and read the Citizens United ruling to see if it is as unhinged as I thought, and every time I do that I see it is actually far more deranged than I remembered.
