the limitless back and forth struggle
over shares of a certain surplus stream
can't happen
if ..the surplus evaporates quickly enough
that is to say
evaporates too quickly at least potentially
to sieze and build the proper cistern and syphon system
to pump it off line
hence the imperative
don't cut your price to your cost
just to grow your market share
once you generalize this imperative
downward sticky pricing
becomes a micro reality
even where marginal firm costs are falling
