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)

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.!
