At dinner, 1YO refused his baby food but happily ate a bite of my plain rice with chopsticks.

Me: Looks like he just wants grown-up food.

6YO immediately objected: Or maybe he just doesn’t want to eat with a spoon anymore. Try feeding him his baby food with chopsticks! 😂

[Tangren Feng @Tang_Ren_]

Me: “Let’s take turns reading?”
5YO: “I read one, you read one.” (Cool.)
10 min later…
5YO: “I read two, you read two?” (Okay?)
10 more min…
5YO: “Three and three?”

She’s negotiating. I fear where this is going ♾️

This afternoon at the library, the kids were doing a craft activity called “Design Your Own Book Cover.” Most naturally started drawing pictures, but our 5YO carefully wrote out the title: The Book With No Pictures. “Mine is a book without pictures,” she declared🤣

Reactions were... very mixed! 😅

Wrapped up the last lecture of Microeconomic Theory today! Shared details about the final and mentioned a fascinating paper by a colleague that ties directly into our course. I spent some time simplifying it into the final exam's last question—a little "gift" for my students.

4YO: I have three things that will never change. The first one is very important: I will always love our whole family. The second one is not as important: I really like funny things. The third one is a little funny: I love eating sesame paste.🤣

She was super nice and the process was extremely smooth. Best vaccination experiences in Italy.

Got my 2nd booster this morning. The lady at the pharmacy yelled out "Aiuto, Inglese!" the moment she found out I don't speak Italian😂.

What social choice functions are ex post implementable when transfers are not available? Only constant, trivial functions — as long as there is some preference interdependence and preference heterogeneity. https://t.co/iE3nfNln4E

[Tangren Feng @Tang_Ren_]

Same here. I shared Massimo Marinacci's view with my students, "Completeness is not a rationality assumption, but rather a non-trivial assumption about the quality of the DM's information, high enough to ensure her familiarity with all alternatives."

[Itai Sher @itaisher]

Since we are talking about complete and transitive preferences, I’ll just mention that when I teach this (like I happened to do today!) I tell students that transitivity is plausibly a candidate for a requirement of rationality but completeness is not.

Ho un pacco dalla Cina a Milano. Anche oggi sul tracking risulta che la consegna non è stata effettuata perché destinatario assente. Tuttavia, siamo a casa e abbiamo un portiere a tempo pieno nell'edificio residenziale. @PosteSpedizioni @PosteNews

[Tangren Feng @Tang_Ren_]

Wow...Received an email from the vaccine center around 3 pm asking me to get vaccinated for covid at 8 pm TONIGHT.

[Tangren Feng @Tang_Ren_]

I know it is kinda late... but we (decision sciences) are hiring too https://t.co/bNNJjkaDpr

@ciacconasz Talking about Chinese state-run media...

[Tangren Feng @Tang_Ren_]

@msiniscalchi @ProfNoto @umichECON has it, since 2017🤫

The Wikipedia article "Big lie" should add this twitter as a 21st-century example of Big lie technique. "If you tell a lie big enough and keep repeating it, people will eventually come to believe it."https://t.co/bRTHfhr1h6

[Donald J. Trump @realDonaldTrump]

The United States shows more CASES than other countries, which the Lamestream Fake News Media pounces on daily, because it TESTS at such a high (and costly) level. No country in the world tests at this level. The more you TEST, the more CASES you will be reporting. Very simple!

[Mariano Max Croce @MCroce_MacroFin]

We are a multi-field group. Econ? Finance? Empirical? Theory? That's OK, just apply! #Research #GreatIdeas #Collegial

[Tangren Feng @Tang_Ren_]
