🚨 New WP 📄 (w/ @muzhou-zhang.bsky.social and @winniexia.bsky.social )

We ask which countries people in 🇺🇸🇬🇧🇩🇪🇩🇰🇮🇹🇷🇴 think their governments should learn from and show:

1) Citizens have clear favorites (Nordics top)

2) Performance info shifts what they prefer and how they explain it

Comments welcome!

This is completely insane and he should be impeached.

It is also extremely confusing. He writes "God Bless the Great People of Iran!" in the same post as he threatens them with annihilation (although I guess it makes sense in a sick way) and brags about having ushered in regime change (he has not).

Popular attitudes are often seen as a safeguard against democratic backsliding: if citizens don’t oppose lib democracy, politicians have little incentive to erode it.

In @cpsjournal.bsky.social I argue that, while intuitive, this reasoning conflates two states of the world:

New in the American Economic Review: migration doesn't hollow out the home economy — it builds it up.

More than 75% of the long-run income gains from migration are domestic. The home economy itself grows.

Do conjoint/factorial/vignette experiments reflect choices in the real world?
Are hypothetical scenarios in the artificial survey context externally valid? Do hypothetical bias, intention-behavior gap and social desirability biases undermine validity?

Two cautionary studies on this question:

The riches of Viktor Orbán’s home village Hungary’s longtime leader is trailing in the polls ahead of April’s election, as the opposition alleges widespread corruption

‼️The FT has launched a four-part series on Orbán and the Orbán government. The first part focused on Russian interference in support of Fidesz; this second part deals with the “family’s” enrichment. You wouldn’t believe it, but the FT mapped out their real estate empire from the air ✈️

🔥Revised paper🔥

More regressions. More tests of mechanisms. Same story. Tldr:

Brexit caused much regulatory uncertainty at a moment when UK state capacity was v weak, and hard-to-regulate companies (aka oil firms) did not think twice and generated a mess in the high seas.

I am extremely honored, and equally perplexed, that my book has received the Stein Rokkan Prize.

Thank you so much to everyone who helped out with this project along the way. So much of the book is the result of feedback by kind people who took the time to listen and read. Thank you.

Wild how economists and political scientists worry so much about unbiased tests **in their papers** and yet basically ignore how their journals filter on significance. Given our noisy tests, the latter creates huge bias away from zero.

It must be very hard to publish null results
Publication practices in the social sciences act as a filter that favors statistically significant results over null findings. While the problem of selection on significance (SoS) is well-known in theory, it has been difficult to measure its scope empirically, and it has been challenging to determine how selection varies across contexts. In this article, we use large language models to extract granular and validated data on about 100,000 articles published in over 150 political science journals from 2010 to 2024. We show that fewer than 2% of articles that rely on statistical methods report null-only findings in their abstracts, while over 90% of papers highlight significant results. To put these findings in perspective, we develop and calibrate a simple model of publication bias. Across a range of plausible assumptions, we find that statistically significant results are estimated to be one to two orders of magnitude more likely to enter the published record than null results. Leveraging metadata extracted from individual articles, we show that the pattern of strong SoS holds across subfields, journals, methods, and time periods. However, a few factors such as pre-registration and randomized experiments correlate with greater acceptance of null results. We conclude by discussing implications for the field and the potential of our new dataset for investigating other questions about political science.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.
