walras's conflation and bad analogy

walras  according to dunc :

d foley sez wrong !!!

   his thermo-con paper:
"A mechanical analogue in
economics would require not only forces, but dynamical
equivalents to inertia."



a mechanical system at rest ie with all forces initially in balance absent a shock willl stay in balance
ie  in equilibrium ie at  rest
and will stay at rest a mechanical system in motion will stay in motion

you gotta go thermal if you want an analogy to utility based exchange systems
fisher found that out thanks to mentor gibbs :


"thermodynamics, and not mechanics, is the correct physical theory
 to explain how disequilibrium systems can converge to equilibrium
and remain there."

 the original thermo con trickster  mr W
 was actually  a  simple newtonian mechanist
without a dynamic theory to get him to equilibrium
and on top of that  operating with a nasty conflation of his the unit level  the trader
and the aggregate level the market system and its total  utility state

come now statistical mechanics

but another errorfisher thinks his agents are analogous to  innocent stocastic objects
particles insideless  balls  in stochastic  motion
AND
Tto the deterministic state arrived at by these particles in mutual and interacting motion
walras/fishers  unit was an optimizing utiliton a simple  maximizer of a substance
it stores or eats
  loose in a  free for all  vol-trade  market opportunity full of other  such concious maximizer units
ready to be  trading for utils  with each other


"The potential minimized at physical equilibria is not the energy,
 as was believed in Walras’s time, but a quantity called free energy
which also receives contributions from the entropy"

"Fisher was ...drawing analogies of the economic agent to both stochastic
and deterministic physical objects at the same time"

"utility .. a measurable
quantity analogous to potential energy in mechanics"
