Super important work by @profsimonb.bsky.social and the team 👍

How do we make sure kids get access good school? Check this ⬇️ work analysing policy alternatives!

they do a difference in disc. study and find increases in absence...

- for low achieving students.
- They also find worse ACT scores.

Read the full paper here: www.aeaweb.org/articles?id=...

Or my summary here: hanshenriksievertsen.substack.com/p/do-lenient...

3/3

Just looking at the raw scores they find a massive shift in the distribution

This could of course be
- reduced efforts by students
- teacher responses

2/N

This week I read the forthcoming paper in AEJ: EP by
Bowden, Rodriguez, Weingarten studying how a more lenient grading policy affected student behavior and outcomes

As the table shows
- pre: min effort for D -> 69 points
- post: min effort for D -> 60 points

Second, the crazy new QJE paper.

Crazy as in crazy impressive. I mean several sources of identification. As a little side note friends are defined by pre-determined friends network based on who calls who. 😮

I wrote about papers here: hanshenriksievertsen.substack.com/p/oh-these-s...

2 new papers on smartphone use

First, a new NBER working paper on Florida, suggesting that phone bans in school in the short run lead to worse outcomes, but improved outcomes in the longer run

With the latest shock to my time budget, I needed something new to spend my time on.

I might have gotten a sign wrong in the calculations

Do teachers use test results? New RCT (in a low stakes setting!) says yes!

New cool study by @scandersen.bsky.social and @tsguul.bsky.social in JPART on how teachers use information from school tests to adjust their teaching.

Hi Sara, thank YOU for the great work. And sorry that I only cover a fraction of what is actually in the paper.

I have on my to do list, to write a post about the value of meta studies more generally, where I might use your paper in more depth.

This new study comes just as Denmark launched a massive school meal trial costing more than 100 000 000 EUR.

A trial that had a bad start, as several schools pulled out. Especially those randomized into the high-co-payment treatment arm.

Do school meals work?

No: according to a new meta study by Sara Ayllón and Samuel Lad summarizing results from 42 studies.

I discuss that study in slightly more detail here: hanshenriksievertsen.substack.com/p/the-causal...

Here is my favourite grant application trick: write the first drafts in British English.

Now, the night before the deadline I can just change all the “ou” to “o” to be within the character limit🥳

Anyone teaching Ed Policy or Econ of Ed this fall? Looking for ideas to keep the class current when everything is in constant flux.

Wow! I think my record is 4 or 5.

In Denmark, new mothers are quasi-randomly assigned to mother groups by nurses.

This new paper shows that being assigned to a group with a depressed peer decreases mothers self-reported mental health + increases mental health care uptake.

Fascinating!
