Arpit Gupta@arpitrage
“The small effects of political advertising are small regardless of context, message, sender, or receiver: Evidence from 59 real-time randomized experiments”

Kevin Munger @kmmunger
Incredible paper. Congrats @aecoppock @vavreck @seth_j_hill
Seriously, gold standard work. Causal evidence that varies:
1) treatment content
2) temporal context
3) sample
while holding everything else constant, with a massive sample.

👮👮👮 search black motorists 3x more than white motorists.
But (!), searches of black motorists don't yield more contraband.

Fantastic null effect of contact study in Afghanistan.
Null effects are *especially* important here because the existing contact literature shows signs of publication bias -- i.e. our literature-prior is that contact tends to work, but the pub. bias may have misled us... [1/4]

Yang-Yang Zhou @yangyang_zhou
📢 New working paper w/ @jaylyall_red5. We ask, can prolonged social contact reduce local residents’ prejudice toward internally displaced persons (IDPs) in a conflict setting? #nulleffects #polisciresearch

Excellent paper on the economics of data just published in the AER (@AEAjournal) by Charles Jones and Chris Tonetti (@StanfordGSB).
Data is non rival and can be used by any firms or people simultaneously, without being diminished. But this can generate privacy concerns.

This paper is an absolute must-read for anyone interested in development and misallocation.
It is one of my favorite papers and can be beautifully summarized in one figure, hence a short thread follow.
Key take-away: a lot of misallocation could be poor measurement.

Some, but not all, of the usual biases have shifted during the pandemic, so it's not obvious that the overall CPI bias has switched signs. Regardless, a lot of these effects are very short term and will have equal and offsetting effects in the rebound. He identifies 4 causes of

Justin Wolfers @JustinWolfers
My latest @nytimes piece: In normal times the official inflation statistics overstate the rate of inflation. But in this upside-down pandemic economy, the usual biases are reversed, and the official numbers almost certainly understate actual inflation.
