Yesterday, I returned to snowy Kiel to receive the award for the best political science master’s thesis. The thesis examines how cuts to local train services affected political alienation following German railway privatization in 1994. Big thanks to @swegmann.bsky.social & @chwmartin.bsky.social!

🚨New publication! Thrilled to finally see this paper out in @psrm.bsky.social 🎉
📊I study how gender shapes coalition preferences among politicians. Turns out mayors prefer forming governments with women-led parties, perceiving them as better communicators and more competent governors.

🧑🤝🧑Do politicians consider the gender of leaders when selecting coalition partners?
➡️Using a conjoint on 979 Spanish mayors, @albahuidobro.bsky.social finds that mayors, especially those on the center and left, prefer coalitions with parties led by women www.cambridge.org/core/journal... #FirstView

In just over eight months, Berlin will hold its 20th state election since 1946. While its well known East West divide in voting behaviour is often attributed to the city’s former split into capitalist and socialist halves, these differences existed even before the city’s division. A thread. 🧵

That's true, but as a newbie I find it a bit confusing when some papers just select one of 3,000 possible matching/weighting methods + a partially arbitrary set of covariates, but don't really explain why that method is the right one and how the results would look with a slightly different set

Thanks for all the great and helpful answers and references!
Does anyone have good resources or papers that explain when to use matching versus weighting for causal identification, and how they differ conceptually?
