IMO a key skill of a good scientist is moving comfortably between the specific & general e.g., relentless in understand the nerdy details of the data (including its coding) WHILE holding onto the big picture of the hypotheses being tested with the data

Truly remarkable how many people have told the Pope, in some way or another, to "shut up and dribble." Or corrected him on the Bible, despite their thin education on theology. Or told him to stay out of US affairs, despite him being a US citizen. The hubris is amazing.

i was surprised to learn that bc most protein powders are considered dietary supplements, they basically fall into a regulatory grey area there's no federal limit on the amount of lead they can contain and neither manufacturers nor the FDA have to prove these products are safe before they're sold
Protein powders and shakes, like all dietary supplements, fall into something of a regulatory gray area.

There is no federal limit specifying the amount of lead allowed in protein powders. And while the FDA requires that manufacturers keep their products free of harmful contaminants, it largely leaves it up to companies to decide what counts as harmful and test their own products for compliance.

Before 1994, manufacturers had to prove herbal products were safe before selling them. That changed after Congress passed the Dietary Supplement Health and Education Act. The law sharply limited the FDA’s authority, leaving supplements far less regulated than drugs.

Today, supplements are “presumed safe unless found otherwise,” says Cohen at Harvard Medical School, and most products face scrutiny only after reaching the market—meaning unsafe or contaminated supplements can reach consumers before problems are caught.

The IRS is laying off people during the shutdown, even though it was rehiring staff it previously fired because it was so shorthanded. This one stands out because firing IRS employees costs the government money, since they bring in about $6-8 for every dollar spent on tax enforcement
IRS Halts Layoff Plans, Begins Rehiring Amid Staffing Shortages
The agency is attempting to rebuild its workforce and restore public confidence.
Treasury Department: Treasury cut 1,446 employees on Friday. Two Internal Revenue Service employees confirmed layoffs were taking place at the tax agency, which has already shed more than 25,000 employees. One employee who was laid off was working Friday and exempt from shutdown furloughs.

We just spent 6 months to add 1 figure to this paper. Some people said, "Couples aren't prioritizing men's careers. Men just have better earnings opportunities when moving." Earnings effects of moves for couples on the left, singles on the right. Negligible gap between single men and women.
Event study coefficients that show that men's earnings rise more than women's among couples following a cross-commuting zone move (left panels). The pattern is muted or reverses among single men and single women (right panels).

Our new paper shows that men benefit from couples' long-distance joint moves more than women do, in both Germany and Sweden. Is this just b/c men are usually the main breadwinner? No, it's hard to explain the patterns we see w/o a gender norm prioritizing men's careers. www.nber.org/papers/w32970
Moving to Opportunity, Together

Many couples face a trade-off between advancing one spouse’s career or the other’s. We study this trade-off using administrative data from Germany and Sweden. We first conduct an event-study analysis of couples moving across commuting zones and find that relocation increases men’s earnings more than women’s, with strikingly similar patterns in Germany and Sweden. Using a sample of mass layoff events, we then find that couples in both countries are more likely to relocate in response to the man being laid off compared to the woman. We investigate whether these gendered patterns reflect men’s higher potential earnings or a gender norm that prioritizes men’s career advancement. We provide suggestive evidence of a gender norm using variation in norms within Germany. We then develop and estimate a model of household decision-making in which households can place more weight on the income earned by the man compared to the woman.

Trump is desperately looking for a scapegoat to cover for his own failure to lower costs for Americans and firing Lisa Cook is his latest move. It’s an authoritarian power grab that blatantly violates the Federal Reserve Act, and any court that follows the law will overturn it.
