A thought module proposed by Bob Haugen, via email:

“Most such discussions (about Economic Calculation) miss what I talked about here:

The short version is that the people who are still talking about the calculation problem do not seem to understand how planning and replanning is done now in capitalist supply chains (as well as US military supply chains), by propagating signals from the end customers or users back along the networks.

“I have maintained that the actual signals by which the advanced capitalist supply chains coordinate their physical production and transportation are valid precursors to, and directly usable by, a very different economic system. They do not depend at all on prices. Those signals are always through a medium, but sometimes indirect (as between agents who do not directly coordinate with each other) and sometimes direct (the agents do coordinate directly with each other, but use messages via some medium to do so).”
