Imagine being talented and beautiful and rich and famous and still the most noteworthy thing about you is how good a person you are.

So many tech people seem to see the conflict between parenting and work as one in which work is the natural and moral victor. If you’re going to automate an aspect of your life, why wouldn’t it be the meetings rather than the spending quality time with your teenager?!

one anecdote: I was searching for a link to one of my old papers on Google, and the automated Gemini summary attributed all of my lab's work to my husband
When utilized in literature review, LLMs consistently 1. fail to mention female authors in female-led literatures, 2. insist that men are more influential or more heavily cited when this is contradicted by objective citation counts, and 3. attribute women’s work to hallucinated male scholars.

If there’s a water shortage, don’t subsidize showers. If there’s a blackout, don’t make AC cheaper. If there’s an oil shortage, don’t cut gas taxes.

Prices are helping signal scarcity. A gas tax holiday weakens that signal right when it matters most.

So it seems that Iran is now the new Denmark (but without the bacon...)
1/ Has Iran managed to reinvent the Sound Dues – the tolls that Denmark imposed for over 400 years on ships entering the Baltic Sea? Recent ship movements suggest that rather than completely blocking the Strait of Hormuz, Iran is monetising it instead. ⬇️

Kaja Kallas: "What I think is actually important for everybody to understand is that the US has been very clear that they want to divide Europe. They don't like the European Union"
"They don't like the EU": Europe's top diplomat says Washington wants to divide Europe - Euromaidan Press
Kaja Kallas told the Financial Times that the United States "does not like the European Union" and has been "very clear" it wants to divide Europe — a charge she levelled as Washington launched new trade probes against the bloc this week.

Agree. It will be critical to preserve EU unity in the face of repeated US attempts to sow division through singling out individual members in the realm of trade.
🚨🚨Symbolically important that EU countries and EU institutions shore up support for #spain in the context of fear of trade retaliation from the #Trump regime. This should be self-evident but unity of EU here is under pressure. 🧵

A reminder that the announcements re the India-EU trade deal are a bit like seeing someone’s dating profile. They have chosen what to share. What really matters is what you see when they turn up in person… (the deal’s text) which may not be for ages.

New tariff just dropped.

Americans set to pay an additional 10% tax on all goods from Germany, the UK, France, the Netherlands, Sweden, Norway, Denmark, and Finland.

It starts in two weeks, rising to 25% by June.

Professor's pro-tip for anyone with college-age kids: Tell your kids go to class. It's really that simple. If you show up, you'll do okay. You don't have to be smart, you just have to be there. Maybe stay off your phones for 50 minutes. Just listen. You'll absorb something. I have data to prove it.

BREAKING: This is huge news, the EU's equivalent of the 🇺🇸Supreme Court's 2015 Obergefell v. Hodges ruling.

🇪🇺Court of Justice just ruled all 🇪🇺countries must recognise same-sex marriages granted in other member states.

This effectively legalises gay marriage across 🇪🇺

Good 🧵⬇️ but I question "more radical". They are different; work differently.

1. Customs union = goods only. EU single market = goods, services (a UK strength), capital and people.

2. Customs union = a common set of tariffs, less flexibility, as ⬇️

There are other options for closer trade relations
There's a prevailing idea in the UK that a customs union with the EU would be a compromise solution if single market membership is not possible, e.g @eddavey.libdems.org.uk and @jonathanfreedland.bsky.social recently. But a customs union is, from a trade policy, a more radical step. (1/N)

Good thread on the impact of the upcoming Supreme Court ruling on the IEEPA tariffs.
The most obvious thing to say about the Court's IEEPA decision is that Trump will continue tariffs no matter the outcome, but that alone misses that each possible tariff authority has its own scope and constraints which means that different tariffs behave very differently with different impacts.

Oh, I see... And here I was, saying to my students just earlier today that you can't put a tariff on services trade... I guess I'll have to revisit that issue next lecture. Sigh. Teaching trade policy in 2025 is not that great unless you actually like to constantly revise your teaching materials!

And now we wait for EOs.
As a lot of people pointed out, this is not going to stop and it will be interesting to see how all the deals hold up, whether or not there will be any exemptions and how these tariffs are applied.

Never a dull moment.
