🧵 New version of our paper (@bcegerod.bsky.social) is finally online: "How Many is Enough? Sample Size in Staggered Difference-in-Differences Designs"
We show that even well-identified DiD studies are often underpowered; sample sizes needed are surprisingly large
Paper: osf.io/preprints/os... 1/6

So much of classic political science research is woefully underpowered.

I'm glad we're slowly coming to our senses.

Got a few new papers coming out with some excellent coauthors.

. @bcegerod.bsky.social and Hye Young You presenting data on what has been happening in the study of money in politics

Thrilled to welcome so many excellent scholars to EGB for the CBS-Princeton Money in Politics this Thursday and Friday. www.cbs.dk/files/cbs.dk... We are looking forward to two days of great presentations and discussions. Watch this space for some timely updates

A person presents in a lecture hall with a slide titled 'What's known, what's coming?' and 'What might we expect?', discussing research and expectations related to Denmark. A banner beside the presenter reads 'DIAS' with the phrases 'Be curious.', 'Be playful.', and 'Be excellent.'.

What are the implications of politicians swapping public office for corporate roles? Interestingly, this ‘revolving door’ might have political benefits for both the public and the private sector.

Thanks to @bcegerod.bsky.social of Copenhagen Business School for making us a little wiser 💡

This a screenshot of the abstract of our paper, called Conviction, Incarceration and Recidivism: Understanding the Revolving Door. It says "Noncarceral conviction is a common outcome of criminal court cases: for every individual incarcerated, there are approximately three who were recently convicted but not sentenced to prison or jail. We extend the binary-treatment judge IV framework to settings with multiple treatments and use it to study the consequences of noncarceral conviction. We outline assumptions under which widely-used 2SLS regressions recover margin-specific treatment effects, relate these assumptions to models of judge decision-making, and derive an expression that provides intuition about the direction and magnitude of asymptotic bias when a key assumption on judge decision-making is not met. We find that noncarceral conviction (relative to dismissal) leads to a large and long-lasting increase in recidivism for felony defendants in Virginia. In contrast, incarceration (relative to noncarceral conviction) leads to a short-run reduction in recidivism, consistent with incapacitation. Our empirical results suggest that noncarceral felony conviction is an important and overlooked driver of recidivism."

Paper🧵!

We....

1) develop a framework for identification w/ multiple treatments in a judge IV design
2) find that felony conviction (without incarceration) increases recidivism relative to dismissal

Thrilled that my article has just been published at @apsrjournal.bsky.social! 🎉 The article argues that low statistical power is a major impediment to acquiring cumulative knowledge on questions concerning cross-national differences: www.cambridge.org/core/journal...

Hej Marc. Jeg vil gerne på listen

Hej Anne! Jeg vil gerne på :)

Public comment and public policy Alexander Sahn Abstract Is public policy responsive to demographically and ideologically unrepresentative comments given at public meetings? I investigate this possibility using a novel data set of over 40,000 comments made at the San Francisco Planning Commission between 1998 and 2021, matched to information about proposed developments discussed in hearings and administrative data on commenters. I document four stylized facts: First, commenters at public meetings are unrepresentative of the public along racial, gender, age, and homeownership lines; second, distance to the proposed development predicts commenting behavior, but only among those in opposition; third, commission votes are correlated with commenters’ preferences; finally, the alignment of White commenters (vs. other racial groups) and neighborhood group representatives and the general public (vs. other interest groups) better predict project approvals.

This new AJPS paper by Alexander Sahn is a methodological tour de force, using tens of thousands of comments to show how public hearing commenters are older, white, NIMBY homeowners who exert extreme influence on zoning decisions at public meetings doi.org/10.1111/ajps... #polisky #PAsky
