Paper summaries

🚨a quick thread about a long-running project now released as @nberpubs WP
This paper is joint w/ @john_eric , @WinnieVanDijk , Danny Tannenbaum, Davin Reed & Nick Mader. It replaces 2 separate studies of eviction in Chicago (Humphries et al) and NYC (Collinson & Reed)

What do we find?
#1 : eviction is typically proceeded by rising economic distress. We find patterns of: falling earnings (below), ⬇️ in employment, ⬆️ in unpaid bills, and ⬆️ in hospital visits.
This suggests many evictions are precipitated by adverse events.

Given the high costs to governments of providing health care and homelessness services, our results imply that there are considerable spillover costs for society from eviction.

What happens when we restrict social media usage? @eggers_felix and I did a fun experiment at @univgroningen during the academic year 2018-19. Our paper is just out in @PLOSONE.

Does diversity affect people's perceptions of income distribution and their preferences for redistribution?

A goal of public education is to improve economic
and social mobility. But schools often assign kids to classes based on academic ability, mimicking the stratification that education is intended to combat. Our new research studies this tracking in the US.

Finding: Tracking increases inequality bc it *increases achievement at the top*
Eliminating academic tracking in the name of reducing gaps is a mistake.
We need to find ways to bring up kids at the bottom while pushing high performing kids to achieve all they are capable of.
Sandy Black @Econ_Sandy
Finally, when we explore how exposure to tracking correlates with student mobility in the achievement distribution, we find + effects on high-achieving students with no - effects on low-achieving students, suggesting that tracking may increase inequality by raising the ceiling.

Here is the key graph for first-time dads.
The blue line plots arrest rates in the 3 years before/after their kid's birth. The other lines show arrest rates over the same ages for men who have kids when 1-5 years older.
The DinD effect is a 20% drop in arrests post-birth:

Useful resource for #econtwitter folks: Sangmin S. Oh maintains a HUGE list of ~plausibly exogenous variation~ used in empirical economics work.
It's called ✨Plausibly Exogenous Galore✨ and it's also a listserv you can join. bit.ly/3Q2ga9j

I'm assembling a list of online math classes that predocs can take before applying to grad school. Many either aren't at universities or don't get free classes. Important to have a lot of good, affordable options throughout the year @predoc_org @cblatts @paulnovosad @tylercowen

Interesting discussions
Tom Moylan@moylato
The World Bank found that 31% of policy reports were never downloaded and almost 87% of were never cited.
But imagine if their experts were trained/supported in building an online community of their own, professionally presenting their work and creating value with each post.

@ipeds_nces just released new data on degree completions for the 2021 class (the first class with a full semester during the pandemic.) History and Religion have both joined English in being down to half their 2000s peak; philosophy's rebound persists, while area studies falls.

Here's the slightly longer term shifts from 2011-2021. The total outlier of computer science's explosion is really clear here: so is the concentration of growth in fields that have clear career prospects.

Here's the really big picture: STEM and medical majors continue to take over. This is a choice that's been made by parents, policymakers, and students. Any talk about what happens to the humanities, the social sciences, even business needs to take this as the starting place.

The downtick in humanities this year pushes up the ETA for when CS is larger than all humanities degrees together to one of the classes currently in college.

Short written assignments are FINISHED pedagogically. Educators need to wake up to this reality. There are alternatives: in-class blue books, oral exams, longer research papers (for now). But AI forces us to rethink our pedagogy.
This took me 10 seconds in GPT-3.

In July, following @jenniferdoleac's example, I hired a photographer for professional headshots. The outcome were pictures which I really like because they represent me well. While the expense was not insignificant, I think professional photos should be part of our development.
