🚨New working paper 🚨
How did migration reshape Brazil’s religious landscape?
Raphael Corbi, Fabio Miessi, and I have a new paper showing that internal migration drove a major religious shift by transforming local religious markets instead of converting migrants or spreading beliefs. 👇

Our own @hannahritchie.bsky.social did a video last year with Big Think called “What the news won't tell you about climate change” — and it just won gold at the 2025 Telly Awards as the best non-broadcast video on sustainability!

I'm thrilled to have my first paper accepted for publication in the Journal of Development Economics. It has been a long journey, beginning even before starting grad school. Let me give you an overview of this paper. (1/n)

This is fascinating!!
Ever wondered why presenting more facts can sometimes *worsen* disagreements, even among rational people? 🤔
It turns out, Bayesian reasoning has some surprising answers - no cognitive biases needed! Let's explore this fascinating paradox quickly ☺️

Hello, #econsky! I have a question for you:
What’s your preferred way to post working papers and track citations?
Are there drawbacks to using repositories like SSRN or arXiv?

Great resource for applied economists
Here's the punchline -- a "checklist" for researchers hoping to either apply our exogenous-shocks approach or the exogenous-shares approach studied by @paulgp.com and coauthors
We pair this with discussion of several real-world papers and how they may or may not fit into the two frameworks

Awesome paper, congratulations!
Martin Koenen and I just came out with a paper that might be of interest to you. We use FB microdata to get a broader but shallower look at the diffusion of shocks (mostly focusing on migration). Would love to chat some time! drew-johnston.com/files/Social...

Trying something new:
A 🧵 on a topic I find many students struggle with: "why do their 📊 look more professional than my 📊?"
It's *lots* of tiny decisions that aren't the defaults in many libraries, so let's break down 1 simple graph by @jburnmurdoch.bsky.social

Great initative!
Do you know junior economists from LMICs?
Please encourage them to apply - chances of being matched seem great and I'm sure the feedback will be useful.
Requirement: "Mentees should be pre-PhD or in a postdoc in a LMIC, with a finished paper ready to share over the next month."

Just re-upping this #econsky: I currently have more mentors than mentees/students (can probably match another 10-11 students from LMICs who would like feedback on a research paper from a senior scholar.) Fill out the form here if interested! forms.gle/ekvvoEKBLYQM...
