I wrote the latest of my occasional guides to which AI to use right now for non-experts who want to get stuff done. The agentic systems available to everyone are getting extremely powerful (even as the names and features continue to be really confusing): www.oneusefulthing.org/p/an-opinion...

Neat chart from @bswud.bsky.social showing that high cumulative doses of radiation can be well-tolerated if spread out over time. I recommend the attached article and the publication Works in Progress in general. worksinprogress.co/issue/how-to...

Ein Gespenst geht um in Deutschland. Die Angst vor der #Deindustriealsierung und dem wirtschaftlichen Abstieg. Wie immer neigt die Debatte zu Alarmismus und starken Übertreibungen. Kaum aber Jemand hinterfragt, ob die #Industrie tatsächlich Deutschlands Zukunft sein kann. 🧵1/9

In the past few weeks, I’ve shown Claude Code to (economist) friends & colleagues and, as a byproduct, created a presentation around using Claude Code for Economic Research. I‘ve now turned that presentation into a more in-depth blog post that you can find here: perikl.is/posts/2026/c...

I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...

I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

A widely held view is that the Gini coefficient is not decomposable by subgroups. This paper proposes an axiomatic framework that ensures well-behaved within and between-group terms under which the Gini is decomposable with a novel and unique formula. buff.ly/XdnzG6F

Ooh, @posit.co's Positron is no longer in beta as of this week(!), and it recently added support for DuckDB databases in the Connections Pane positron.posit.co/connections-... - any db connection you add with {connections} shows up there—this is magical! #rstats
Screenshot from Positron showing code that connects to a database, and then highlights the connection in a Connections Pane and shows the data in a Data Explorer tab

Here's the code:

library(dplyr)

# Connect with {connections}, which automatically adds this to the panel
con <- connections::connection_open(duckdb::duckdb(), ":memory:")

# Or do it manually with {DBI}
# con <- DBI::dbConnect(duckdb::duckdb(), ":memory:")
# connections::connection_view(con)

# Add some stuff to the database
copy_to(con, penguins, name = "penguins", overwrite = TRUE)
copy_to(con, gapminder::gapminder, name = "gapminder", overwrite = TRUE)

# Get stuff out of the database
adelie_query <- tbl(con, I("penguins")) |> 
  filter(species == "Adelie")

# Check it out! It's SQL!
show_query(adelie_query)

# Actually run the query
penguins_from_db <- adelie_query |> 
  collect()
penguins_from_db

connections::connection_close(con)
# Or this: 
# DBI::dbDisconnect(con)

Olivier Blanchard argues that we should understand better the macroeconomics of the medium run, and I could not agree more. Since I have been working on this for a while, let me show you why this is a promising field for young researchers!

The Case Against Streaming TV Shows
New streaming TV shows ask for a 20-30 hour time commitment. Unlike network TV, you will often be binge-ing alone and may never even get a pay-off (or the pay-off will suck).

It looks like not all Germans living in Spain are living in Mallorca after all! (Map created with a tool by Pablo García-Guzmán: pablogguz.shinyapps.io/dataviz_migr...)
A map showing the absolute amount of German immigrants in different Spanish provinces. Surprisingly, there are quite a few German immigrants in e.g. Alicante, Santa Cruz de Tenerife and Málaga (besides of course Barcelona and Madrid), although one would think that all Germans would move to Mallorca/the Balearic Islands.
