Diane Keaton, who died today, at 79, was “one of the most comedically pure and brainy actresses in our midst,” Penelope Gilliatt wrote, in 1978. https://www.newyorker.com/magazine/1978/12/25/diane-keaton-her-own-best-disputant

One’s won two IMO golds and the other’s published in Econometrica. Their 30-min joint press conference? Both gave respectful, elegant, articulate, honest and intelligent answers. No questions avoided, no hype, no drama —just two uncharismatic yet incredibly smart people. Presidents doing their jobs.

Clever Cockatoos Have Figured Out How to Drink From Water Fountains

Aussie birdies are generally loud, social, and a joy to watch. Sulfur-crested cockatoos, in particular, are ubiquitous in cities, and their mischievousness always brings a chuckle or two: www.nytimes.com/2025/06/03/s...

Nicușor Dan — two-time International Math Olympiad gold medalist, PhD in mathematics from Sorbonne Paris North, and former mayor of Bucharest — has just been elected as the next President of Romania. From math problems to national ones. Good luck, Nicu! Q.E.D.

I partly share your intuition. Still, e.g., AU has highest migration/capita, yet ranks middle. Perhaps mobility is higher in countries with less inequality, which supports upward mobility, and where income quartiles are closer, making it easier to move from the bottom half to the top quartile?

Funny how to understand social learning in these externally influenced networks, one would probably have to start from... those basic mechanical-diffusion or naive-learning models (like the simplest ones used to model the spread of infectious diseases).

Assuming increased volume and quality of flows bring us closer to sufficiency, Ben's claim about *some* industries seems valid. Must it hold *across* most ind. for dominance? By analogy with requiring an underlying matrix to be either irreducible (some) or primitive (across), I lean towards "yes".

I'm rusty and might be missing something but... h is an info set ("horizontal" set of indistinguishable decision nodes). h^\preceq is a history ("vertical" set of decision nodes: one from each "eligible" h, where the partial order \preceq would have to be set up to determine the "eligibility").

Oh. Ok. From one of your earlier replies, it seems you may also need to keep track of histories. How about: h for an info set. H for the collection of infosets. H_i are i's info sets. H^t the set of possible histories at t, and h^t a specific history.

Pausing to carefully consider a notation choice... nice! For what it may be worth, I'm echoing Ben: iota for info sets and I for players --which is also consistent with MWG's excellent notation for extensive form games (pg. 227).

I made a theory starter pack. It includes some CS/Econ, pol-econ, and behavioral types as well... Lmk if you'd like to be added (or removed!) and I'll do my best - the edit functionality is a bit wonky atm

We proposed a formal definition to distinguish quality from quantity; then, we tested LP- and invariant-methods, and the IF (~GS), against it (no axiomatic characterization though). I'd do it differently today, but for any sensible def. of what "we want" that I could think of, GS is not the answer.
