🚨 New Working Paper 🚨
We show that applicants manipulate their address to get access to their preferred school and thereby push out non-strategic students.
Friday, so I am giving you 3 options. A gif, a 🧵, and the full paper!

Do you remember Andrea?
- she used her grandmother's address to secure a place at West Beverly High!

Does this also happen in real life?
- We looked at real data from Danmark (of course )
- We observe a lot of address changes around the high school application deadline

And it didn't use to be like that
- Before school priority was based on distance to school, we didn't observe any changes around the deadline!

The number of address changes doubled!

And this was NOT poor Andrea, but kids from more affluent households

Interestingly, the response is driven purely by 15y old changing the address without any other member of the family changing address!
- There is no response in family moves

And this affected non-strategic applicants!
- More than 1/4 who did not enroll in their preferred school would have been offered a place in absence of manipulation by their peers

But is this cheating?
- Well when a municipality started to ask for additional proof that the 15y really lives at the new address, the effect was reduced significantly !

What if we suddenly removed all strategic address changes?
- The non-strategic peers who got pushed out of schools would get better peers!

Summary
- Applicants manipulate their eligibility at schools.
- Manipulation pushes other students out → who get worse peers.
- See paper for theory, proofs, placebo tests, decomposition of response, and much more.
