The skepticism of economists towards simulation in general is reflected in the following dissection of Jay W. Forrester's World Dynamics (Wright-Allen Press, Cambridge, MA, 1971):

  • "Measurement Without Data", William D. Nordhaus, The Economic Journal, Vol. 83, No. 332 (Dec., 1973), pp. 1156-1183. [1]

We would do well to study this example (as well as from the much later Aspen project.) --Ken 01:34, 1 October 2008 (EDT)

This Economy Does Not Compute

By MARK BUCHANAN Published: October 1, 2008

A short excerpt:

Well, part of the reason is that economists still try to understand markets by using ideas from traditional economics, especially so-called equilibrium theory. This theory views markets as reflecting a balance of forces, and says that market values change only in response to new information the sudden revelation of problems about a company, for example, or a real change in the housing supply. Markets are otherwise supposed to have no real internal dynamics of their own. Too bad for the theory, things don't seem to work that way.
