New papers
I am excited to share some new research on historical immigrant enclaves and upward mobility
Joint work with @stats4geo and Ran Abramitzky

1/n Thread to describe this paper
NBER @nberpubs
How to estimate a production function, esp in a developing country? Check out my forthcoming paper in REStat. Bottom line: many popular methods don't work when input markets have frictions or firms are constrained (1/N)
The Review of Economics and Statistics (REStat) @restatjournal
Do films become “better” over time? Or, to put it differently: is there cumulative cultural evolution in film history? Our new paper with Peeter Tinits @yrgsupp approaches this question [a thread] /1
🚨⏰🚨A NEW PAPER (not about COVID)🚨⏰🚨
When does competitive equilibrium exist when goods are indivisible (hard!)+income effects (harder!)?
Everything turns out to be obvious once we knew the answer: income effects don't actually matter for existence! sites.google.com/site/ravijagad…
New paper by economist @MNDjourel showing with rigorous evidence how language can matter:
When the Associated Press stopped using the term "illegal immigrant", there was a causal effect on readers' views on immigration policy.

^good methods discussion in the replies
How do peers in school affect the long-run mental health of students?
Jonathan Norris (@StrathBusiness) and I show how students’ relative ranks in school affect their mental health both immediately as well as in the long-run.

Public goods
Big week for public goods in finance:
Very important paper, Open-source Cross-Sectional Asset-Pricing by Andrew Chen and Tom Zimmermann.
They included STATA and R code for 105 characteristics and 945 portfolios with alternative rebalancing frequencies.
On the same topic, @Andrew___Baker has some interesting R code to clean data from CRSP and Compustat: github.com/andrewchbaker/… Check it out!
Reform proposals
In philosophy, there is a resource called the Stanford Encyclopedia of Philosophy which is: a) written by leading scholars, b) up to date, c) free, d) comprehensive. The closest things I know of in econ are the JEP and JEL, but these are lacking on b)-d). (ht: @ben_golub)
^lots of discussion in the replies; the New Palgrave Dictionary of Economics (dictionaryofeconomics.com) and Annual Reviews (annualreviews.org) are underrated
Proposal for colloquia/Brown bag talks during a pandemic:
Everyone records a 45min talk & puts it on Youtube. Departments can check them out & select those they like.
Then they show it during their colloquium hour & invite speakers to do Q&A.
No travel, no cost, no risk.
👏👏👏👏 Q: how do we ensure jr ECRs get their share of attention?
Idea: have pairs of talks, where senior researcher is paired with jr researcher. Like how musical groups with market power choose an opening act they want their audience to see. *many* bands broke out this way
