5: However, we do find that pre-registered RCT studies with a complete pre-analysis plan (PAP) are significantly less p-hacked compared to pre-registered RCT studies without a PAP (5/N)

What happens when the treatment variable is misclassified in DID designs? This could occur when exact treatment timing is unknown, or treatment groups are estimated. In our new WP, we show that the DID estimand does not have a clear causal interpretation (1/3)

Traditional power analyses rely on formulas and are only available for simple settings. Many modern/complex research designs don't have a corresponding power formula. How can you estimate power without a formula? Simulation! A 🧵 re: our recent paper

If you're interested in simulated power analyses. You can check out a paper with @leticiafcnunes @KosaliSimon and Bernie Black here

Interesting paper using UMETRICS data from a bunch of universities to look at what happens when a researcher receives an NIH grant: science.org/doi/10.1126/sc…
They hire more people, who produce more research. But magnitudes debatable; authors argue not a mechanical hiring effect.

🚨New Paper Alert🚨 What are the welfare effects of dynamic pricing in oligopoly markets? We offer new theoretical insights and empirical estimates for the airline industry. Spoiler alert: Little intuition from single-firm settings carry over; the welfare effects flip sign. (1/n)

If you are an active undergraduate on Econ twitter and become friends with a whole lot of leading economists at great phd schools I feel like that has to increase your odds of getting into those programs even if those professors insist it doesn’t

John Ruf@JohnRuf6
@ModeledBehavior I made an engineering substack post one time about the mechanics of caterpillar swarms and @AnthonyLeeZhang liked it and got me an initial interview for my current job as a predoc.
Now here I am waiting for my code to compile while eating lunch.

pining for an econ textbook in the tradition of math texts like "Counterexamples in Topology" where we just go through nice simple true-sounding statements in econ and cleverly tearing them apart

your perpetual reminder that the "9-month-contract" is a useful fiction that allows academics to consult and do other work while being employed full time. you would not earn 3 extra months' salary if you switched to a "12-month contract".

@leightjessica @annalilharvey @mosenkis @tom_wein @caitlin_tulloch @3ieNews @NSF Something I keep fantasizing about is like regional RCT conferences where local admin and researchers can meet to design El Cheapo RCTs.

This is a great example of market design: journals.uchicago.edu/doi/abs/10.108…
It is also a great example of the failed econ publishing process. The "new" mechanism started in 2005. Data from 2005-2011. I saw Canice's talk in 2013. What good does it do for the JPE to "publish" it in 2022?!?

I like these article highlights — Elsevier showing they can still add value to the publication process.
