May this mark the end of a horrible chapter in the Middle East, and inspire peace around the world.

What do you notice about this map?

From the BITSS newsletter I received yesterday: “Over the past five years, BITSS has supported the development of free, publicly accessible platforms like the Social Science Reproduction Platform (SSRP)…with funding from the Arnold Foundation and the Alfred P. Sloan Foundation.”

Actually, Trump is threatening to do something that Biden never did. The threat is about SECONDARY sanctions on Russia’s trading partners, not just more primary sanctions on Russia. This is a long overdue move. Seems Trump is finally coming around to a correct strategy. 🤞

That’s a hero. Give this guy a medal.

amazing!

The not-so-subtle point: “With access to Ukraine’s military strength…Russia could transform itself from a debilitated country…into a far more dangerous adversary capable of threatening many other countries beyond Ukraine.” www.project-syndicate.org/commentary/u...

I used to discourage students from using sports data in their econometrics term papers but I’m coming around to the idea. There’s some great teaching resources here: emeyers.scripts.mit.edu/emeyers/teac...

@tderyugina.bsky.social argues that in response to the Middle East war the West must increase military support for Ukraine. These wars are related - there is no doubt that both Russia and China back Iran (and nukes it probably has are from Russia) voxukraine.org/en/democraci...

“On the nineteenth of the month, some 2,000 Union soldiers…marched into Galveston. From the balcony…Granger delivered the news that some 250,000 souls held in bondage were now free…it became a custom within the African-American community…to celebrate June 19, shortened, of course, to Juneteenth.”

“…I believe Boaz would agree with…to continue to extend support for Ukraine short of direct military intervention...Ukrainians are currently fighting against an invading aggressor…The libertarian idea…is the…right to live…as one chooses so long as they are not infringing upon that…right of others.”

“We then summarize the first 487 reproductions uploaded on the SSRP. The results show substantial heterogeneity in the ability to successfully reproduce empirical results in economics…approximately 30% of recent studies meeting at least a basic definition of being computationally reproducible.”

Congratulations to the editors of the Journal of Economics, Race and Policy, on your journal’s first impact factor! For a new journal like JERP, it takes time to get established. But the strong initial numbers are exciting. I believe the journal is poised for continued growth in the years ahead.

What a class act.

“Soviet and Russian histories like to start the history of World War II in 1941 when the Soviet Union was attacked by Nazi Germany. There's a good reason they gloss over the preceding years — … the Soviet Union collaborating with the Nazis in order to carve up Europe between them.”

It's wild to me that in 2025 there are academics advising their students to never use AI.

Stalin engineered a famine that killed millions in 1932-33, killed thousands more during the Great Terror of 1937-38, and signed a pact with Hitler and invaded Poland in 1939. But, the Great Patriotic War, as it’s known in Russia, only started in 1941 when Hitler invaded the Soviet Union.

My article on using replication methods in undergrad econometrics courses is now out in The American Economist. Thanks to the editor Diego Mendez-Carbajo for leading a productive editorial process that improved the article. journals.sagepub.com/doi/10.1177/...

@profholian.bsky.social research shows that more Ukrainians living in the US started speaking Ukrainian, and more US-born people started identifying as Ukrainians after Russia's full-scale invasion voxukraine.org/en/identity-...

Telegraph calls this not a peace plan but a capitulation. [I disagree. The alternative is to accept Russia demands for disarmament of Ukraine and transfer of non-occupied territories — that would truly be surrender. The Trump administration is simply articulating what it's already doing.] 8/

Very proud of my uncle, Mykhailo Holian, for conducting this concert in a filled cathedral before a riveted audience in Chicago’s Ukrainian Village. abc7chicago.com/post/chicago...

If you are in Chicago on this Palm Sunday there will be a beautiful benefit concert in Ukrainian village. My uncle will conduct.

It’s exactly what Russia is doing. My SJSU colleague Ulia Gosart is organizing a fundraiser for a library in Ukraine. The library was destroyed in 2023, yet librarians continue to work as Kherson continues to be attacked daily. Please give! None is too small. www.gofundme.com/f/restore-br...

American universities are exporters when they earn revenue from foreign students. Making it harder for foreign students to come here is like putting a trade barrier on yourself.

The words in English, Russian and Ukrainian: English: Peace, World Russian: Myr, Myr Ukrainian: Myr, Svit.

I am very happy that the editors took our report seriously. Hope more retractions will follow.

I finally have a publication date for my new Experimental Economics textbook: December 12. Equally as important, I am proud to have negotiated a low price for the book: $38.10...for a nearly 800 page book! You can find the book here: www.amazon.com/Experimental...

If a man say, ‘I love God’, and hateth his brother, he is a liar. 1 John 4:20

Statements by President Trump and Vice President Vance regarding yesterday's massive Russian drone strikes on civilian populated areas in Ukraine and the killing of civilians:

The auction is now over. The buyer who “won” bid $19.50…but unexpectedly (to both them and me) had to pay $1.41 in sales tax. Seller paid shipping. So they ended up paying $20.91 for a $20 bill. This is the Winner’s Curse in action!

What happened today is a dark moment in our history. One bright spot in this madness that I see are the many lawyers and advocates across the country who spent their Saturday fighting like hell to preserve justice in the face of horrific cruelty. And we will keep fighting ✊

The current high bid is $10

There are other people selling bank notes on eBay. But we’re the only ones who are smart enough to sell it for less than face value.

My daughter and I are starting to sell on eBay. Bid on our first item! It is a $20 bill. Buy now for $15! We would be honored if you were our first customer. www.ebay.com/itm/14645608...

Yesterday was Pi day. Celebrating it is a great opportunity to get kids excited about math. The connections with music are a great topic for all age groups. Younger students can measure and represent tempo, rhythm and pitch.

Remember when converting references to APA was a pain?

🙏 Sybiha presented US Secretary of State Marco Rubio with an icon of Mary made from a box of ammunition!

President Trump has mentioned figures provided to Ukraine as high as $500 billion, while the real value of US aid is closer to $50 billion, of which $18.3 billion was military aid. Detailed interview from Anastassia Fedyk on the recent Econ4UA study: www.sestry.eu/en/statti/ho...

Kudos to Dean Karlan and his team for their valiant efforts to improve the cost-effectiveness of foreign aid. We'll find a way to continue this important work together.

Here is a better estimate of the costs of US aid to Ukraine. Now imagine $ value of the security these resources enabled. That’s an excellent NPV.
