Want to know what the cost of war is? Recent news reports estimate we have fired approximately 850 Tomahawk missiles into Iran with an average cost of 2.5 million per missile (just the missile cost). Total cost? Around 2 billion dollars. Lost aircraft? Esitmated at about 3 billion dollars.

Why does this timeline suck so bad?

Going to the moon again is so cool. I wish it didn't take 50 years for us to go back, makes me want to be an astronaut.

My CRRA coefficient is -0.07. My probability weighting function evaluated at 50% is 59.3%. I made 50 decisions. Estimate your rank-dependent utility preferences here: jamesblandecon.shinyapps.io/RDUAdaptive/

#Econsky: I'm presenting new research at #ASSA2026 in a @sgeecon.bsky.social session this Monday at 8 AM titled "Does remote work slow growth and promotions?" Please join us!

#Econsky My co-author and I have a new paper we are presenting at the AEA Meetings, papers.ssrn.com/sol3/papers..... In this paper we examine Difference-in-Differences (DiD) from a time series perspective and provide three main results.

Is it just me or do DAGs (Directed Acyclic Graphs) not incorporate time? I don't know if I have ever seen one explicitly deal with that dimension but maybe I missed it?

Was a bit of a drought due to covid + post covid health issues, but a couple of papers in the accepted column in 2025 (got the second email today!) is the right way to come out of the funk. Hopefully more to come!

I like #EconSky as a medium to find out about new research, but find the ability to sustain a conversation about it difficult. Would there be value in having an Econ Discord server where we could have more nuanced and detailed conversations? Does one already exist and I just don't know?

Leadership is (among other things) about both being willing to make a personal sacrifice for others, and recognizing the moment when the needs of the many outweigh the needs of the few (or the one) so as to prompt that sacrifice.

It is so hard to be positive these days. Can someone give me something positive? Cat pictures? Baby pictures? Good news? Anything out there?!

Anyone have recommendations on an e-ink tablet? Thinking about diving in to give structure to my reading list/notes, etc.

I'm going to post this here too: semi-hot take, the frequentist definition and interpretation of probability is wrong. The concept of probability as a long-run frequency only holds in a single dimension. Beyond this, frequency and probability are no longer interchangeable.

OK #EconSky. What are your thoughts on: 1. The rate at which you make a Type I error should be less than some desired rate. 2. The probability of making a Type I error should be less than some desired probability. Do you think rate = probability? Under what conditions do you think this holds?

It constantly surprises me the amount of human capital we invest into the areas of incentives and allocation of scarce resources as a field, but we can't figure out how to incentivize good referee reports and editor communication. #EconSky
