If HMRC isn't interested in punching through opacity in corporate structures to collect all other types of tax that are evaded and avoided, idk if a wealth tax is going to change their minds

But I'm not sure how you get your transparency-via-wealth tax without it? Also not clear that the places that do have a wealth tax make corporate structures more transparent to the public, which is the channel through which pressure mounted in the above example

If you want to make real estate ownership transparent, you could just do... that. Most real estate in England and Wales owned by corporates is covered under the beneficial ownership register. There are gap which should be plugged - but those gaps don't apply to the tax authority.

While I'm sympathetic, I'm curious how you think a wealth tax would have been the thing that made a difference in the above case

Self-recommending. @johndellosso.bsky.social is an excellent investigator and this seems like a great way to train the next generation of bright young sleuths

"America will get better and better," declared the Reverend Jesse Jackson on the stage of the 1988 Democratic National Convention. "Keep hope alive."

Find some hope today in Jackson's speech as we remember the life of one of America's civil rights icons.

Crypto and Human Trafficking: 2026 Crypto Crime Report Cryptocurrency flows to suspected human trafficking services surged 85% between 2024 and 2025, reaching a scale of hundreds of millions.

What is never very clear from @chainalysis estimates is whether they are measuring a true intensive margin, or just a measurement extensive margin: in the past year they just got better at detecting human trafficking www.chainalysis.com/blog/crypto-...

Grumpy opinion:
Too many young development economists are working on behavioral econ questions that are unimportant for development. The topics are amenable to small experiments that can nail mechanisms and demonstrate smarts via a clever design. The profession over-rewards those attributes.

Very happy to have had the chance to present our work (w. @mattcollin.bsky.social & @szakonyi.bsky.social) on the effects of the Economic Crime Bill and its beneficial ownership transparency on secretive real estate ownership in the UK.
