@lianda_edu We are actually merging, forming a very complementary team; it will be very common to use all the computer theory in economics and economic theory in computer science.

@liberaldeantoo2 HPE la considero útil si lo ves sin darle tanto peso a los clásicos, y dirigido hasta la frontera actual de conocimiento. Cuando lo ponen muy de bandos entre escuelas es un asco muy al estilo ciencia política.

@mean_field_zane @IvanWerning @40yoap conditions for the recursive equilibrium under menu costs—the functional space remains bounded and geometrically stable. That mathematical regularity is the exact prerequisite Werning's out-of-equilibrium operators need to guarantee existence under state-dependency.

[Alejandro J. Lagos C. @AlejandroJLagos]

@mean_field_zane @IvanWerning @40yoap Fair critique. Staines doesn't construct an isomorphism to Calvo for macro policy sims; his focus is structural convergence. My point is spectral: since he proves the price distribution decays super-exponentially to the stochastic steady state—satisfying existing eigenvalue...

[Alejandro J. Lagos C. @AlejandroJLagos]

@mean_field_zane @IvanWerning @40yoap Yes, Staines (2026) proves that under menu costs, price distribution decays super-exponentially, yielding a Calvo system with an endogenous reset probability. This allows Werning to extend his forward-looking stability to a state-dependent model that is computationally tractable.

Super excited to share joint work with @axiommathai that kicks off a broader project of formalization in economics.

Aumann's celebrated theorem says we can't "agree to disagree."

But what does that actually mean – formally? 👀

[Ivan Werning @IvanWerning]

Excited to FINALLY release toughest+most rewarding paper I've worked on...

….we attack a 150 year old Walras question that's gone unanswered, not for lack of trying (Hicks, Samuelson, Arrow; our chances?😱)...

Q: Is the market equilibrium stable or unstable?¯\_(ツ)_/¯

[Alejandro J. Lagos C. @AlejandroJLagos]

@mean_field_zane @Ahlurahul The Dixit-Stiglitz framework is analytically restrictive as it collapses the substitutability matrix into a homogeneous scalar. Mapping the characteristic space onto a Riemannian manifold generalizes local substitutability as an endogenous topological property induced by...

@mean_field_zane @Ahlurahul When will the article with Oberfield and Rossi-Hansberg, which surpasses one of our pillars in this field, be published?

@StarobinskiA @dm_somoza Esta en error, el objeto de estudio son los fenómenos económicos en sentido amplio, que un problema social pueda estudiarse partiendo de sus elementos no la desprende de su elemento social, igual que una pandemia tiene agentes portadores y se puede estudiar desde la bioquímica.

Technical change often simplifies the tasks performed by labor. This raises productivity. But it can also erode the bargaining power of workers.

My new paper “The Commoditization of Labor” (with Fukui and Nakamura) is about this.
