Paper summary threads

🧵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.

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

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.

During my Lamfalussy fellowship at the @BIS_org, I wrote a paper for its annual conference on “The constraint on public debt when r < g but g < m”.
A short thread on economic policy implications from the paper. (Ungated at bit.ly/3m2BmOX)

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

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?

NBER @nberpubs

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

🎉Publication Alert🎉
Extremely proud and excited to announce that my master's thesis "Monetary Policy and Production Networks: an Empirical Investigation" is forthcoming in the Journal of Monetary Economics!

🧵Thread on key findings


Our @nberpubs paper proposing a new method to design short survey modules:
Measure a latent construct using both qualitative interviews and many close-ended questions.
Select for the module the questions most correlated w/ the coded qual data.

So thrilled to see “Estimating The Anomaly Base Rate” with Andreas Neuhierl and Michael Weber published at the JFE @J_Fin_Economics!
doi.org/10.1016/j.jfin…
Here is a quick thread on what we do… 1/n

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

The NBER YouTube channel just posted a series of truly fascinating interviews with econ legends! Here is with Anna Schwartz, November 19, 2001. She got inspired in 1931(!) to study econ by her high school econ teacher ! youtu.be/bX3DzpkTDDw via @YouTube

Interesting discussions

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.

The State of Development Journals 2021: in my annual gathering of statistics on leading development economics journals I look at Quality, Acceptance Rates, Review Times and how much did the pandemic change journal submissions? blogs.worldbank.org/impactevaluati… 1/4


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
