The "genetic algorithm" behind the process of optimizing balance when matching treated and control units

Francesco Bromo @francescobromo.bsky.social · 1d

It's all survey data. There is no DNA, this particular matching approach is called "genetic", but it's got nothing to do with biology 😅

Francesco Bromo @francescobromo.bsky.social · 1d

It's a standard matching approach where we attempt to isolate the effect of country of origin by matching respondents on other covariates (e.g., gender, education). To optimize balance, we used genetic matching, as opposed to one of the alternatives. We do not explicitly test mechanisms.

Not sure that would get IRB approval 😅

Just a much more humble statistical approach: kosukeimai.github.io/MatchIt/refe...

Genetic Matching — method_genetic

In matchit(), setting method = "genetic" performs genetic matching. Genetic matching is a form of nearest neighbor matching where distances are computed as the generalized Mahalanobis distance, which ...

New JREP paper with a team of amazing co-authors❗

We use CMPS data (2008-2020) + a genetic matching approach to examine how country of origin shapes the voting behavior of U.S. Latinos, revealing substantial variation in party ID and electoral choices.

It's been a long time coming... José Cheibub and I have a new @thejop.bsky.social article! All the questions you've ever had (and were too afraid to ask) about caretaker periods in parliamentary democracies won't be answered here, but it's a start!

The "Parliamentary Events Dataset" covers 36 countries between 1945 and 2024. As well as recording events related to government formation and termination, the dataset includes a classification of full-power cabinets and caretaker periods. Data/documentation available here: github.com/bromofra/Par...

Francesco Bromo @francescobromo.bsky.social · 8d

We show how datasets of parliamentary cabinets disagree over the length of caretaker periods, the lifespan of individual cabinets, and the number of cabinets. Our goal with this project was to provide a framework (and dataset) for systematically identifying full-power cabinets and caretaker periods.

Francesco Bromo @francescobromo.bsky.social · 8d

We draw a conceptual and empirical distinction between "full-power" cabinets and "caretaker" periods and introduce a new dataset of parliamentary events. We use the dataset to present an analysis of caretaker periods and show that these have gotten longer, on average, since the end of the Cold War.

As one does, I spent many evenings walking around the golf course in College Station, TX thinking about caretaker periods. A lot of that thinking went into this new JOP article co-authored with José Cheibub: doi.org/10.1086/738892

📢 My last PhD paper is out in Legislative Studies Quarterly 📢

📌 Main finding
➡️ Party control of speaking time in parliament limits MPs’ geographical focus
➡️ Open access increases constituency representation

One small good thing happened this week. A new piece just joined my collection. Not quite a first edition, but close (also inscribed by WB’s wife)

It’s me (hi!), your favorite government-initiated-votes-of-confidence guy, with a table update: French PM Bayrou just lost a (simple) vote of confidence in the National Assembly.

I’d have so many questions: could it be dissolved? Would it have confidence prerogatives? (I believe the Australia UC doesn’t?) How will the back-and-forth re legislation/amendments be regulated? Questions that keep a parliamentary institutions scholar up at night 😅

@paologambacciani.bsky.social and I have a new project on Al-powered parliaments. We reviewed Al tools and applications in legislatures across the globe and wrote down some thoughts on the potential and limitations of parliamentary use of Al for legislative studies: ubwp.buffalo.edu/jopblog/2025...
