Paper summary threads
NBER has a new working paper that tries to describe America's homeless population by linking Census data with administrative data from various other sources. nber.org/papers/w28861?…
I always find this back-of-the-envelope growth accounting exercise striking.
Most of US growth since the 50s can broadly be attributed to temporary “transition dynamics” (1.7 pp of the 2% annual rate). https://t.co/XzEqosG6Vh

From 2008 to 2015, a national survey asked American adults whether they experienced feelings of sadness in the day prior. This graph shows daily sadness over that time range. What happened in the middle of December, 2012 that caused a sudden spike in sadness?
Their main findings:
To prevent 1 homicide, need to hire 10 more cops.
Those 10 cops, then, will:
* Make ~70 more low-level arrests
* PREVENT ~15 serious-crime arrests
* Prevent ~20 serious crimes (almost all via deterrence)
* Cause ~8 use of force incidents
new study finds that, at least so far, the pandemic has not caused much movement between cities and regions. Instead, most moves have been from denser areas to the suburbs within the same region. nber.org/papers/w28876?…
Challenge accepted, Pam! Not only will I convince you but I will do so in 6 tweets or less. But I need more than one so I started a new thread (is this what you do?). Here’s what I need for this result: 1/6

Countries can integrate either through flows of goods or migration of workers. Policies often reduce barriers to both - e.g. the European Union. In a great paper forthcoming at @JPolEcon, the authors build a quantitative model to study their interactions. See 👇 a nice 🧵 on it

An old debate on startups: is it the jockey or the horse? That is, does the idea or the team matter more? This is a hard thing to measure, but this paper uses the death of founding team members😬 to show that the team matters a lot: startups never recover! papers.ssrn.com/sol3/papers.cf…
Do open or closed electoral lists favor women's representation in politics?
A regression discontinuity in Spain shows that closed lists increase female candidates, councilors and mayors, perhaps driven by gender differences in the supply of politicians and party bias.

Interesting discussions
A brief thread on morning sickness and the ability of women to be fully represented in economics/academia. And men, please don't run for the exit - you're my target here. I promise to be brief and not graphic. 1/n
(THREAD) I want to share a few thoughts about the stagnation/decline in the *lifetime incomes* of men since the 1970s. It's perhaps been the most crucial factor shaping the current US social/political landscape.
First, here is a nice summary of key facts by @BeckerFriedman
