THE PRICE OF WAR "A war of average intensity is associated with an output drop of close to 10% in the war-site economy, while consumer prices rise by approximately 20 percent. The economic ramifications of war are not confined to the war site" (American Economic Review Vol. 116, No. 3, March 2026)

This book should definitely include a chapter on the 'wesanderson' color palette package for R. Watch out for 'wes_palette("Darjeeling2")' in my future figures!

In just over eight months, Berlin will hold its 20th state election since 1946. While its well known East West divide in voting behaviour is often attributed to the city’s former split into capitalist and socialist halves, these differences existed even before the city’s division. A thread. 🧵

This Chanukah book was published in Warsaw in 1930. Unfortunately, no records of its former owners survive. The Looted Books Project works to reunite looted books with their original owners and descendants. Chanukah Sameach!

„Anyone who would choose Lithuania as an enemy has also made an enemy of the United States of America“. An inscription in Vilnius from 2002 — one can only hope those words are still remembered.

Canadian PM Justin Trudeau: "Today, the United States launched a trade war against Canada - their closest partner and ally, their closest friend. At the same time, they're talking about working positively with Russia, appeasing Vladimir Putin - a lying murderous dictator. Make that makes sense."

In DC, Polish history isn’t hard to find. On my morning run, I encountered Kościuszko and Pulaski—Polish soldiers of the American Revolution. Their statues near the White House are fitting reminders as we are currently working on polish influence in the U.S.!
