In times of war, pandemic, or other emergency, particularly when there are quick shifts in the environment, it seems that the sorts of coordination that are amenable to top-down approaches on a large scale become more significant, while the sorts of coordination that they're bad at, or that lower-level coordination is good at, don't change. In Coase's framework, this suggests that the optimal firm size has suddenly gotten larger. (It obviously has other, more political/legal implications as well.)
