@AlexKontorovich This is a reasonably bold hypothesis.

@soboleffspaces Is Josh Angrist considered an applied econometrician?

@CJSprigman Hi Chris, love the experimental approach to test legal criteria, but external validity is usually hard (or prohibitively expensive) to establish. Wondering if such an approach can be realistically operative and if so, what requirements should be imposed.

@emollick great paper! but just becoz majors and skill requirements correlate along dimension X, doesn’t mean they are intentionally sorted along dimension X right? Also wondering how much “majors as skill bundles” is treatment or selection.

Fascinating visual on artificial-intelligence talent moving around the globe. Takeaway: botching our visa policies would cost the US a long-range strategic asset: top talent. https://t.co/69JNCsJSO7

@causalinf @yudapearl Q: Are PO and DAG really symmetric or can PO be considered more of a "reduced-form" of DAGs?

@DrEricDing The paper assumes an unrealistically short incubation period (4 days). This will significantly bias upwards the estimated transmission rate beta in order to match the number of reported cases -- might be part of the reason for very high R0.

Who could say no to a Cantonese opera about Donald Trump? Especially one where he apparently wears a blonde toupee and squares off with Mao Zedong in table tennis.

@JustinWolfers Just shows people have found a really good classifier

[Jonathan J. Mao @jonathanjmao]

@YAppelbaum @dylanmatt @DKThomp agreed. But I'm surprised by the sig diff in performance they found (+.12 to .6 in future grades)

@YixiangZeng Not much to see nowadays. But the history is fascinating and one of the lesser known chapters of shanghai history
