Continuously overthinking about decision making for a living @iesebschool. RT = things I want to read at some point.

Americans have no idea how difficult legal immigration is for "high-skilled immigrants".

I have 4 degrees incl a PhD. Einstein visa. 250K salary at FAANG. Lived in this country since I was a teenager.

I won't be able to obtain citizenship until middle age

Lovely obit of Harry Markowitz, who developed modern portfolio theory in his '52 article: to maximize returns under risk aversion, buy negatively correlated assets in a particular way. An idea so novel & useful it's hard to see what people did prior to it! https://t.co/CldHP1gJrJ

Rest in peace Daniel Ellsberg. May we all have such moral courage when destiny comes knocking.

Ellsberg’s story gave me hope in dark times. In 2017, I spoke truth to the authoritarian government in Singapore and lost a home.

Unfortunately, indiscriminate use of the term "fixed effects" to describe any set of mutually exclusive and exhaustive dummy variables seems to be generating confusion about nonlinear models and the incidental parameters problem.

This thread illustrates the difference in reaction between economists and other people.

Other people: “Oh no!!! AI is going to cause massive amounts of blackmail.”

Economists: “Well, I guess it will be impossible to blackmail anyone with pictures now.”

Hi #EconTwitter!

Interested in 𝐜𝐚𝐮𝐬𝐚𝐥 𝐢𝐧𝐟𝐞𝐫𝐞𝐧𝐜𝐞?

Check out this brand new JRSSb #Statistics paper, where the focus is in causal effects on distributions, rather than summary measures such as ATE.

New concept: the average causal effect map!

Cool stuff 😀

I thought about trying to get off the treadmill this summer, but not yet. The next version of my DiD workshop is online, June 8/9. All proceeds go toward supporting a reduced workload for first-year MSU PhD students. @MSUEconomics

I gave GPT-4 a budget of $100 and told it to make as much money as possible.

I'm acting as its human liaison, buying anything it says to.

Do you think it'll be able to make smart investments and build an online business?

Follow along 👀

The failure of Silicon Valley Bank (SVB) is the result of two failures of the regulatory framework. What's more, the US banking system is on average facing the same problem that lead to SVB failure: more failures might follow soon. A thread...

This survey paper by Susanne Schennach on unobservables in economic, statistical, and econometric models is magnificent. #EconTwitter

@jmwooldridge Not the (in)famous acronym for linear mixed models?

Cosmic question for @jmwooldridge and #EconTwitter at large: what's the best procedure for assessing goodness-of-fit in LMM?

Machine learning is changing how researchers code unstructured text. A new paper in SMJ, with the ML code and the dataset.

Look, if everyone is worried about students cheating on essays for AI, instructors can just cheat right back.

I asked OpenAI to give me an essay question & make a rubric for grading. I had GPT-3 actually write the essay.

I then had the OpenAI grade the essay & give comments. ✅
