Abstract: How do voting laws impact elections? We highlight how laws targeting a specific group of citizens can have weak effects on turnout and vote shares but substantial effects on policy platforms. To parse these effects, we analyze a model of electoral competition with endogenous turnout and targeted voting costs. Each party anticipates the direct effect of raising one side’s voting costs: discouraging targeted citizens from voting. Consequently, both platforms shift towards the untargeted group. These platform adjustments mobilize targeted citizens and demobilize the untargeted, muting the net impact on turnout and vote shares—consistent with scant empirical evidence of these electoral effects. Yet, on policy they also hurt targeted citizens and their aligned party. The targeted group’s size amplifies these effects. Our results address party competition, voter participation, and representation, as well as normative and empirical evaluations of voting laws.

After working through second and third derivatives, I am ready to abandon Bayes learning for something with an easier functional form.

Currently in FirstView: In “Measuring the Quality of Answers in Political Q&As with Large Language Models,” @rmichaelalvarez.bsky.social and Jacob Morrier develop an approach for measuring the quality of answers in Q&A sessions using data from the Question Period in the Canadian House of Commons.

These always strike me as strong associations and I’ve always wondered how these observed rates vary by field. Eg: effect of family background of becoming an MD/physician or JD/lawyer?

If we write papers using LLM generated data, and those papers are then used to create another version of LLMs and then new datasets for new papers, will the process converge? If not, will it be stationary?

Modeling Violent Terrorism as a Tug of War Between Competing Groups Mike Gibilisco, professor of political science, and his co-author seek an understanding of how competing terrorist groups react to one another's violent attacks.

There are social scientists at #Caltech, @caltech.edu! I think they do pretty good research...at least some of the time.

This is close to stenography:
“An unnamed source told me all these things [many clearly false] so am repeating them to you”

How is this different than publishing a press release?

What Remains of U.S.A.I.D. After DOGE’s Budget Cuts? (Gift Article) The few hundred programs that survived DOGE’s purge reveal the future of foreign aid.

What remains of USAID? Practically nothing ("a shell") and millions will die because of Trump and Musk

Social, Behavioral, & Economic Sciences is getting hit with a 67.6% cut, worse than other programs within NSF. Funding for archaeologists comes from the division for Behavioral and Cognitive Sciences, which is facing a 77.3% cut.

It appears every post doc program has been 100% cut.

TO BE PERFECTLY CLEAR, THE PROPOSED NSF BUDGET CUTS NEARLY A QUARTER OF A MILLION PEOPLE FROM NSF ACTIVITIES. FOR INSTANCE, JOBS.

@caltech.edu and I both agree that international relations needs more theoretical models and fitting those models to data.

To the best of my knowledge, skip day involves seniors planning a series of puzzles and challenges for the rest of the students.

Even after 8 years, I don’t fully understand caltech’s skip day, but this is the first year with an inflatable dragon outside my office.

Happy to see that this is now out. The R package associated with the project, IRTM, can now be found on CRAN. Or can you still download it from my github. We'll continue to update it over time. This is a brief thread about what IRTM can do. 🧵 (1/7)
