Farm owners convicted of exploiting migrant workers continue to claim millions in subsidies.

Our investigation traced dozens of EU payments to farms that have breached, are under investigation for, or have already been convicted of labour-related offences. @journalismfund.bsky.social

Something seems a bit off about this figure. Seems unlikely that Disney would have made 100% of its revenue from one segment in any given year

I love London so much. So much.

Did you know that London has the lowest level of ethnic violence of any city of comparable size in the world?

Multiculturalism has in fact worked here. They just don’t want it to be true because we happen to have a Muslim mayor.

We find that Russian brokers handled transactions worth nearly $6b more than a synthetic group of Russian brokers, following the invasion, highlighting Dubai's role as a haven for sanctions and conflict-driven capital flight

3) More precise estimates of Russian investment post-Ukraine invasion:

To do this, we used published data on real estate brokers and transactions, used a ML name-prediction service to determine which were Russian, and tracked how those purchases evolved after the evasion

2) More evidence that tax compliance for non-residents owning real estate is extremely low: in addition to the direct evidence we present on Norwegian taxpayers, media reports suggest a similar level of evasion for other countries

In total we estimate about $2.7 billion a year goes undeclared

Non-GCC nationals weren't allowed to own real estate in the city until the early 2000s, after which certain areas were desginated as being eligible for freehold ownership

This liberalization led to a surge in the housing supply and an extremely rapid rise in foreign ownership - now approaching 50%

This is an update of earlier work, but I want to focus on a few things we've added to the project:

1) We've used confidential transaction data to go back and time and chart the growth of foreign-owned residential real estate in the city.

🚨New working paper🚨

In this updated work with Annette Alstadsaeter, @bluebery-planterose.com , @gabrielzucman.bsky.social and @andokl.bsky.social , we use leaked data to chart the rise of offshore real estate in Dubai

Notably, the UK does the "higher taxes for immigrants" thing (they have a special tax that notionally pays for their healthcare from NHS, even though they also pay all the regular taxes that British citizens pay which fund the NHS), and the UK still has the same populist-nativist problem as the US

I'm kind of shocked that anyone is still proposing technocratic solutions to the "debate" over immigration. Even if this were a good idea (and it is not), Republican elites and media will never tell their base about it. You can't policy your way out of a propaganda problem!
But we could also go much further. One idea might be to tax immigrants themselves at higher rates and restrict federal benefits until immigrants have met some threshold of tax payments or achieved permanent residency.6 This is not a prospect that brings me joy. But I do think that these are necessary preconditions to warming the public to the idea that the economic math of immigration works out in our favor.
