Paper summary threads

Matt Clancy@mattsclancy
🧵on a great paper. Identifies thousands of cases simultaneous discovery (different scientists, same discovery) and looks at what’s associated with a decision to commercialize. Two important ones: interdisciplinarity and prior collaboration with an entrepreneurial scientist.

Matt Marx @marxmatt
open-access 🚨 article out this week in ManSci: "Revisiting the Entrepreneurial Commercialization of Academic Science."
joint w/David Hsu, and only possible thanks to programming & data crosswalks from @AndyContigiani @startupecon @KRoyMyers 🙏/1

^“*not* prosecuting non-violent misdemeanors dramatically *reduces* recidivism without increasing local crime rates”, thread

Max Roser@MaxCRoser
This just got published and is very good.
A new study that asks: How has extreme poverty changed in the last 2 centuries?
The authors estimate poverty in many ways.
Their main innovation is to rely on 'a cost of basic needs approach' based on Bob Allen’s recent work.

Interesting story about a prison gang reducing violence by essentially creating a parallel set of rules and justice system

IPA @poverty_action

Jason We Need 6 Million Shots a Day Kerwin@jt_kerwin
The final version of our paper is now out as an NBER WP! I updated my blog post about it here: jasonkerwin.com/nonparibus/202…
Short on time? Here’s a quick tweetstorm about what we did & what we found.
We started with a question: why would you ask your employer not to pay you yet?
1/N



NBER @nberpubs
Allowing workers to defer their wages proves popular and facilitates asset purchases. The demand for this simple form of savings is partly because it addresses self-control issues, from @lassebrune, @EricChyn, and @jt_kerwin https://t.co/TiMt7DRq0R https://t.co/Dam0D5yzJg

In a nutshell...
Savings of low-income HH -> bank deposits -> bank loans -> small firms
Savings of high-income HH -> stock market -> big firms
Relatively more income in hands of high-income HH -> small firms have fewer resources & create fewer jobs relative to big firms

Our @nberpubs paper proposing a new method to design short survey modules:

Select for the module the questions most correlated w/ the coded qual data.

The resulting “anomaly base rate” varies over time. Eg, a new finding published in 2002 was more likely to hold up out-of-sample than a similar result in 1992 or 2012. So you might have traded on a predictor with a marginal t-stat in 2002 but not ten years earlier or later. 6/n

Paul Milgrom has recorded (voice+slides) this ~ 3-hour lecture on his perspective on auction theory. This is the best intro to auction theory lecture I've seen, with some modern stuff on Matroids and greedy algorithms. #EconTwitter

Interesting discussions

Chris Blattman@cblatts
I realized that I need to more formally teach some of my project staff how to manage upwards. Today I told one that "You have to treat any busy manager like an ADHD toddler who needs clear and constant instructions and reminders. Especially professors."

I often tell prospective PhD students that success in many PhD programs isn't about being a bright and beautiful flower. It's about being like slime mold, able to persevere and thrive without attention, water, or light.

John Horton @johnjhorton
@cameron_pfiffer Honestly, I think cultivating the ability to go without any praise or positive feedback for months or even years is important. It’s very hard to do this job unless you’ve decided you just like doing the work and don’t care too much what others think.

A note to people writing awesome, detailed, empirical papers ... if you provide sufficient details for someone *writing a model* to replicate your natural experiment, that would be absolutely awesome, then we can directly replicate your work and hold our models accountable to it
