#econtwitter is there a code implementation of Chodorow-Reich et al. (2025) Network GIV?

@glenweyl @curtis_yarvin Ah, I mean that the proper conclusion of Curtis' complaints about democracy should not be 'we need a CEO dictator.' but rather, 'we need to improve procurement.' You could ironically use his arguments about the firm to argue in favor of communism.

@cremieuxrecueil Hi Cremieux, What are you thoughts on the Nevison 2014 paper? She bounds the growth rate in US autism in a pretty convincing way imo. https://t.co/JNkdthB2LA

@ole_b_peters Hello. This is really cool! But, doesn't EUT cover this if you explicitly model out dynamics? e.g. you can derive the kelly betting formula by maximizing expected log wealth, so most Macro models with value functions should be fine, no?

@econspence but is it the man-optimal one or woman-optimal one👀?

[George Yang @iamgeorgeyang]

He's super cool! He spent the last few years working on a nonprofit that assists caseworkers in managing documentation for those experiencing homelessness. Please retweet!

One of my favorite papers in recent years included this diagram. It shows the impact of controlling for three different types of variables: confounders, colliders, and mediators.

With confounders, control is good. With the others, you ruin your result by controlling.

Hi #EconTwitter!

Looking for some #econometrics lecture notes?

You can find a lot of great stuff @ Herman Bierens' (@penn_state) website, covering undergrad, panel data, time series, semi-& nonparametric #econometrics!

Herman is an amazing econometrician, don't miss out!

The true number for teens currently 20 years old, if I were to guess, is probably closer to ~7%. But that's still a shockingly large number.

[George Yang @iamgeorgeyang]

I recently googled the % of teenage girls that get pregnant (after watching the movie, Juno, which was great, btw). A number of my male colleagues were utterly shocked.

[George Yang @iamgeorgeyang]

A slower-moving average is given by the CDC's survey, which has 27% of women surveyed having a birth before age 20. So, yes--still very surprised.

@Jabaluck @itaisher Exploratory modeling, leading to building Dynamic Adaptive Policy Paths vis a vis Decision making under Deep Uncertainty is the clear alternative.

@metaculus @fianxu are working to build a platform that supports this type of public analysis

In ruins of war, donors rush in with aid. With standard infrastructure destroyed, they often give money direct to communities through CDD. Does it make lives better in the long run? Our evidence suggests it does--real econ differences 11 years on from RCT. Now in @EJ_RES 1/n

@harijayashankar not bad! :) [sorry for late reply--didn't check twitter...]

[George Yang @iamgeorgeyang]

@harijayashankar also, hope everything's going well at UMD! hope this isn't an indictment of the 23a real analysis class.

[George Yang @iamgeorgeyang]

@harijayashankar I think it'd be nice if more top programs admitted more students, allowed them longer time periods to finish their traditional first-year reqs, and kept quals/prelims. That's how Nancy Birdsall completed her PhD.
