Sticky prices are not a thing

Prices in an economy are like monomers in a plastic polymer polymers. Individually there is litte resistance to change, they are not “sticky” as neo-keynesians assume. Looking at all of them as a whole in an economy it becomes unlikely that a bunch of prices will go in the same direction. And indeed in <&eichenbaum2011> the authors find that individual prices are not sticky, but reference prices are.

But again, entropic forces can be overcome with coordinated action. <&smith2017>

This reminds me that there is no theory of inflation.
