A new DP is out: papers.ssrn.com/sol3/papers.cf…. @IsabellaMasetto and @diegoubfal reproduced "Targeting High Ability Entrepreneurs Using Community Information" by Reshmaan Hussam, Natalia Rigol and @BenRothEcon. The paper’s results are robust to all robustness checks. See below!

Did mobile money transfers during COVID-19 increase social distancing in Ghana? A new paper with @deankarlan, @RdoseiOsei, Isaac Osei-Akoto, @BenRothEcon, and @chrisudry. 1/

@cerenbaysan Thanks!!

Hey #econtwitter, Natalia Rigol and I are developing an MBA class where we introduce students to tools from applied econometrics for assessing social impact. 1/3

@LauraBoudreau @mike_luca @RDMetcalfe @mslater_johnson @steve_tadelis Thanks for the leads! We'll reach out in the near future :-)

@BenRothEcon @mike_luca @RDMetcalfe @mslater_johnson For DiD, I teach cheap talk in bargaining on ebay (Backus et al, incl. @steve_tadelis). I also used some COVID DiD papers this year. Happy to chat if it's useful!

@dbroockman @peterlorentzen Awesome, thanks!

@Susan_Athey Will look into this. Thanks so much!

@BenRothEcon I used R studio cloud, which had some glitches, but allowed me to control their environment. I created markdown scripts that did a lot of work for them (load/clean data, basic version of analysis) so that they could worry less about syntax and more about interpretation.

@jondr44 👍 👍

@BenRothEcon I have a survey of recent DiD papers in leading journals here -- perhaps some are useful jonathandroth.github.io/assets/files/r…

We’d also gladly accept any advice/tactics about teaching applied econometrics to MBA students :) 3/3

We are looking for pointers to good DiD and RD papers that assess programs that could be implemented by a nonprofit or business (so not pure public policy evals but most other things would count). Any suggestions would be greatly appreciated! 2/3

COVID Lockdown: How India's Food Supply Chain First Tightened and then Recovered @hmmlowe of @UBC and @BenRothEcon of @HBS have a detailed piece, well worth reading thewire.in/economy/lockdo… via @thewire_in

🍎Good news from India🍎 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]

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 @BenRothEcon and @nadhanael: [1/N]

@hmmlowe and I turned our tweet into an article for The Wire: thewire.in/economy/azadpu… Special thanks to @nadhanael for joint work and @DhirSimranjeet and @Toshan15566914 for field assistance!

India's lockdown has led to ~50% drop in fruit and vegetable volume at Azadpur wholesale market in Delhi (Asia's largest wholesale fruit and veg market), though some signs of recovery. More from work with @BenRothEcon, @nadhanael: [1/N]
