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🥳

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!

Beautiful and simple thread on different ways of visualizing the distribution of one variable.

Clear plots, beautiful examples.

Joey Cherdarchuk - Obumbratta @obumbratta.com · Jul 16

The list is by no means exhaustive, HOPs, horizon charts and I'm sure other charts can be and have been used to show distributions. But attached is a handy one pager to summarize all the methods discussed here

Plotting distributions. 16 different ways to visualize one data set.

OLS estimation

Who get's more weight?

Interesting. You would cluster at task level, or? Do they share the data somewhere (I could not find it in my 30sec search)
