One worry has been that India's strict lockdown would lead to more deaths from starvation than from COVID-19. But one positive sign is that by the end of May food supply chains had largely recovered. Thread: [1/N]

Love this paper on caste identity and labour supply by Suanna Oh (): almost half of the workers refuse to do a 10-minute caste-incongruent task even when offered 10x their daily wage!

on preferences for competition.
Parental choice leads to smaller gender gap in preferences for competition than allowing children to choose for themselves. Why? Paternalistic parents act against what child wants.

Of course it's obvious that large transfers should matter more than small transfers. But the point here is that they are so much more effective that we should prefer to spend $X on large transfers than $X on many small transfers. Welcome back big push development economics. [N/N]

Or vulnerability:

This is a fascinating paper -- huge anti-transgender discrimination goes away completely after discriminators chat amongst themselves about their decision-making.
Totally non-obvious that a chat could have so much debiasing power. Would love to see this tried in other settings!
Excited to present my JMP: Silence to Solidarity
My job market paper studies whether communication between discriminatory people can lead to large reductions in discrimination

I had to teach my Introduction to Psychology class today to 300+ students from my cell phone while I was trapped in my apartment building elevator with my two young kids.
This has to go down as my most surreal and stressful teaching experience.
Fact
#4
: most surprisingly to us, there is no evidence that within a given state, supply chains were hit harder in the districts that had COVID-19 deaths. This suggests that supply chain disruptions are driven more by state policies than by local fears of the virus. [7/N]

@BenRothEcon
and I use data from 1800 wholesale markets across India to track food volumes and prices since the lockdown. We (cleverly) distill the data into "Four Food Facts". [2/N]
Fact
#2
: wholesale prices increased by ~10% during phase one, but have since returned to a downward trend. They are now ~10% 𝑙𝑜𝑤𝑒𝑟 than before the lockdown. [4/N]
These facts together suggest that India is enjoying a broad-based recovery of its food supply chain, though of course this tells us nothing about the demand-side: though food is available, there may be many that cannot afford it due to lack of work. [8/N]

Second, a decent habit in grad school is to learn how to generate ideas rapidly, get feedback, kill bad ideas quickly, pick the best idea and push it. Once-per-semester research proposals are helpful, but don't teach this iterative process of the idea-by-idea Hunger Games. [3/N]
Surprisingly, you read this far, so thank you. This is a snapshot of the experiment, read the paper for:
(1) Some evidence on the (non-)importance of equal status and a lack of intergroup competition
(2) Boring robustness checks

It struck me today that the title of my job market paper is so clunky that anytime I have to enter it into some form I have to open the pdf to double-check.

A thought on deception in econ experiments: experimental economists tend to avoid deceiving subjects for at least two reasons: (1) it makes the IRB process quicker, (2) econ referees are thought to dislike deception. [1/N]

The killer figure is now upon us. The mapping of productive assets in 2011 to those in 2007 is S-shaped! The paper does more work to convince us this is really causal (recall: the variation on the x-axis here was not randomly assigned). This looks like a poverty trap. [12/N]
What does this mean for development policy? Small transfers (e.g. typical microloans) may only have temporary effects. Large transfers are more likely to persistently improve income. [15/N]
Food supply to 1800 markets across India has fallen by roughly 60% since the lockdown, with some signs of improvement in recent weeks. More from work with

Also, I should add that I think there are two of the best conflict related papers in recent years. I used to think social contact theory was tired and exhausted, and sports and development was overrated. These papers changed my mind.
"Thank you for your truly insightful point -- it has changed the way I think about economics, and I have changed the writing in the paper accordingly. Specifically, see the newly added footnote 57."

, any suggestions for recent papers I should teach?
I slept through a zoom lecture of mine in early-2020. I woke to messages from students asking if this was some kind of Lord Of The Flies classroom experiment, which actually is kind of a brilliant idea.
Any others have faculty fail stories?
Remember how we were joking last week about how nobody knows what timezones anything is in anymore? The session actually started an hour earlier than what I posted here. Really sorry everyone for that screw up and I hope you were not all as late as I was, yikes.

A new prejudice reduction paper in Israel:
Jewish elementary school kids watched videos of Arab, visually impaired, and immigrant children answering blunt questions about their group (that people might usually be afraid to ask). [1/4]
My solution: PhD students write up a 1/2-page research idea every week. Full marks if make *any effort*. I read them, and give detailed feedback. For really good ideas, I suggest they hand in the same idea next week, with feedback incorporated. [4/N]
Finally, our guess would be that even as cases continue to rise, the recovery will continue: given that supply chain disruptions seem to have been driven more by policy than local risk mitigation. [9/N]

1. This is going to be a somewhat long flood full of gratefulness and appreciation. I'm thrilled to announce that I got accepted to my dream program, Behavioral Science PhD at the University of Chicago Booth School of Business.

Me: what's economics?
Dad: I think it is about employment and inflation and stuff like that, not sure tho
Me: ok I'll drop chemistry and do that instead
Economists seem to have two paths to becoming economists:
(a) my parent(s) is an economist
(b) it was a complete and utter accident, I had no idea economics was something I would be interested in until X happened.
