Some fields list authors alphabetically. Others use norms like "senior last". Others use order to signify relative contributions. In a new paper with @kevinzollman.com, we model the evolution of these norms, and then look at which type of norm is best for science. doi.org/10.1098/rsos...

Can state-building disrupt rather than stabilize society? Thrilled to have a new article in @apsrjournal.bsky.social w/ @mikealbertus.bsky.social showing that the expansion of state communication networks spurred rebellion for decades in France before the Revolution. 👉 doi.org/10.1017/S000... 🧵1/7

There is growing interest in HPE about social conflict in the run-up to the French Revolution. In a new article at Data & Corpus, I describe the Jean Nicolas Database, a database of 8,516 rebellions in France (1661-1789) 👉Article: doi.org/10.46298/dc.... 👉Database: doi.org/10.7910/DVN/... 🧵1/6

One of the big puzzles in history is why the first demographic transition began in France, as early as 1789. With Paula Gobbi and Marc Goñi, we show that a key driver was the French Revolution and its inheritance reforms. Now forthcoming at JPE 👉 www.journals.uchicago.edu/doi/10.1086/... 🧵 (1/9)

Billions of regressions ≠ robustness. My new PNAS Letter shows how unjustified models can drown out justified ones — and why thoughtful model selection matters👇 www.pnas.org/doi/10.1073/...

New working paper, just five short years in the making! The idea for it emerged from reading about the French Revolution during COVID lockdowns, which warped my sense of time, and got me interested into measures thereof. Abstract and title below, and full ms here: papers.ssrn.com/sol3/papers....

Please repost this widely. This is fantastic material. Organize reading groups (ideally bipartisan ones + a good dose of independent)!

Let's brainstorm over strategy Imagine you were part of the strategy team of a major US university: 1) what would be your short-to-mid term strategy to respond to current attacks on higher ed? 2) Who / how would you organize? 3) For what objectives? 4) With what means?

After a long wait, the working paper for the Many-Economists Project: The Sources of Researcher Variation in Economics. We had 146 teams perform the same research three times, each time with less freedom. What source of freedom leads to different choices and results? papers.ssrn.com/sol3/papers....
