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
If input markets are flawed the usual production function estimators may not work.

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:

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)

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

Did economists start tweeting more when the the nation went into lock down? Yes - nearly twice as much initially.
This graph shows the total number of original tweets each week produced by the 1,363 economists registered with rePEc. The red line is the approximate shutdown week.

An amazing *randomized trial* on Twitter+academia:
112 papers were randomly chosen to be shared on twitter by a group with ~58k followers or to not be shared. Papers that were tweeted accumulated 4x more citations compared to non-tweeted papers over 1yr.
