I've discovered that you have much more fun as a tourist if you don't know what the exchange rate is.

I feel like I've heard critiques of economics as a discipline since as long as I've studied economics. Has anyone done a historiography of this?

I guess it's a sign of the field's influence that people seem to care so much, so maybe it's a good thing. At the same time, I can't help but think...why?

Less related to recent events than it may seem, but I wanted to post this at some point:

My Retractions paper, with brilliant coauthors Duarte Goncalves and Jack Willis, was accepted at Restud earlier this year, and is now on the journal's website.

My dog will literally climb on top of me while I'm working on my laptop but then start to growl in discomfort if I hug him back. Make it make sense.

Attempted murder of a Jewish governor and his family on Passover is not a headline story for @nytimes.com and @washingtonpost.com. I’m relieved that Shapiro and his family survived the attack.

I've taught game theory for several years now (maybe like, 10 times?) but somehow it only now just hit me that mixed strategies in Bayesian games are pretty damn weird.

If I shared the ITYSL meme with Tim Robinson in the hot dog suit every time a Republican said that Putin is out of control, I wouldn't have time to do anything else.

Roses are red,
A noise ball is blue,
But when you find out it's noise,
The info will not undo.
