initial assumptions


one point often over looked
is the intial condition assumption

what impact does it have to always "start" the system at equilibrium ??

in fact why assume anything more then
certain  dynamic mechanisms
certain in media res "conditions"
and
a relevent "store of history" in the agents

--of course make em  heterogenious as to stores of history
 and time to act bounded
even if all agents have identical choice mechanisms we call
                                   rational deciders --


sure eventually once the raft of internal inconsistencies gets unknoted
and if ....if
   " external shocks cease"
things might indeed
wind down ... err settle on a path of sorts
but so what


"time enough "??
really ...when will that be relevent
and at least because
"external shocks cease "
is impossible
even if only the "wealth effects " of out of "equilibrium trading occur  ..must occur

what of economic fairness
if much is wind fall gains and losses

not to notice
agent "life span "
as in
 out out brief candle

too much to chew here admittedly
but i didn't cut the bite sizes eh ??
we see these assumptions and narratives everywhere

okay
i'm into realytics
i'm armed with lerner / vickrey
not the harvard yard /infinite corridor ivy teeter totter
i can brush off these idiotic assumptions

they are not in my paradigm

one i suspect quickly gets to the conclusion
for policy considerations
an initial steady state is beyond convenient
to irrelevent  and utterly pernicious

even if analytic beauty arises with such a consideration
the slant of realism is lost hopelessly and to only one advatantage
laissez faire corporate clown car ops

buy --among other things --
an up front assumed "real " existence of such a mental contrivance
and you are doomed to vindicating
corporate hegemony

how's that for hyperbolics
