Simple resolution: the market isn’t maximally efficient at all
information discovery but it is optimally efficient as far as is practical. The economist math still works.
I buy that markets are like a traveling salesman problem. “Impossible” in the general case, but good enough could algorithms exist. Where’s the economist formulation of that algorithm? What are the policy implications that fall out of that?
I admit I’m not particularly well versed in this space, but I’ve never come across that formulation, only the “pure” one the original researcher says is internally inconsistent. I don’t necessarily buy “it’s close enough it doesn’t matter” given what I perceive as many notable exceptions.
