Is this a glitch, @aeadata.bsky.social ?

And an excellent paper "Roger Guesnerie: an Hors catégorie carreer" www.jstor.org/stable/pdf/1...
We shall miss him very much

Roger Guesnerie worked on hard topics. Second-best. Deep sources of rational expectations. Nonconvexities in production. He sometimes used new (to us) math for these hard topics. Y'all Econ kids, work on something hard.
