Now conditionally accepted at @thejop.bsky.social. Very proud of this paper. Full paper here: shorturl.at/TjEWx
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.

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?

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?

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.

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)

That's great. I got: something along the lines of "it must be hard doing theory instead of empirics because we are discovering new data all the time but the number of theoretical results left to discover does not grow."

Overall, we hope the paper demonstrates why correlations between violence and measures of competition cannot detect evidence either or against outbidding nor will they estimate equilibrium effects. And we show how the structural approach can alleviate these issues.

Our second change is we vary each groups’ incentives to compete. When Hamas has greater competitive incentives, both groups use more violence, which is an encouragement effect. When Fatah becomes more competitive, both groups use less violence, which is a discouragement effect.

Mike Gibilisco @mgibilisco.bsky.social · 14/03/2025
The reason Fatah violence depresses Hamas violence is a discouragement effect: when Fatah is very popular (after Oslo II) Hamas is deterred by a rival that is more effective.
