as well.
I question whether formal models can
describe/explain complex phenomena like human communication
or whether they merely translate them into a form in which they are
amenable to logical operators.
Thanks for the comment -- you are very right to question

contain many components which are not strictly "economic" but which are
essential reflections of the state of society. They also typically

Now, suppose Doug runs the simulation and finds that Canadian employers

new full-time jobs.

I, on the other hand, do not. I have seen little evidence that you really

What I find intriguing and potentially exciting about the simulation

This is a reply to several more messages about my project to do a
simulation of the world economy, but before I get on with replying,
I'd like to clear up some possible misunderstandings.
Since my post containing some tentative requirements analysis the
silence has been deafening, with even
Didn't chaos theory grow out of weather forecasters being humbled by what
their super computers were suggesting from simulations? Didn't it have to
do with what happened when the number of decimal places being used were
increased or decreased. Aren't measurements always approximations?
Also,
I've done some tentative impure requirements analysis for a simulation
of the world economy. I say impure because I can't get design ideas
out of my head. It is probably best to admit this up front and also
to hint broadly at what these design ideas are.
Currently I envision this project
