Economic Dynamics / Teaching Economics

Henri, you might also want to talk to Prof. N. Talbot Page at Browns dept of econ. He developed something along the lines you mention. Matthias Ruth and I have a book on the optimal use of natural resources: Modeling Dynamic Economic Systems (Springer Verlag), including a good bit of microeconomic m...

Historical Quotes

Chief Seattle did have an authentically recorded speech at about this time and it is the equal of the faked one. You can find it in Indian Oratory: famous speeches by noted Indian chieftains, Vanderwerth, W. C.,: Norman, University of Oklahoma Press, 1971. I find the authentic version far more persu...

Resource allocation models

Very nice as usual George. I am reminded of the way in which the Japanese produce steel. Nippon and I suppose another one or two of their largest makers would go to the government during a time when sales fell below capacity and make the following offer: We can run only our most efficient plants and...

Is System Dynamics an "accurate" modeling tool?

Maybe Fidelity is the word we are looking for: Modeling Fidelity, rather than modeling accuracy. The Fidelity is to the assumptions in the model.

The Tragedy of the Commons in business

MANY COMPANIES MUST FACE THIS PROBLEM. ARCO BRINGS THESE VARIOUS DEPT HEADS IN, LISTENS TO THEIR APPEAL, ANALYSES THEIR ARGUMENTS IN THE CONTEXT OF THE OVERALL BENEFIT TO THE WHOLE AND DISTRIBUTES ITS PROFITS ACCORDING TO THAT EVALUATION. SURELY THIS IS STANDARD. Bruce Hannon, Jubilee Professor From...

SD + GIS ?

We have been linking cellular STELLA models together and using GIS maps to parameterize and add intervening information, for about 8 years. see: http://blizzard.gis.uiuc.edu/htmldocs/TES.html for some of these models. The cell number varies from around 2000 to nearly 120,000. The platforms vary from...

SD vs. Econometrics

Jon Noble, the best way I have found to think of this question is to regard the dynamic model as a giant regression equation, that contains more than a little specific knowledge about the process involved. Then manipulate the parameters in the model within their known ranges until the best fit with ...

Is there a "theory of system dynamics."

I could not agree more with the statement below by Professor Forrester. Daniel Dennett (Darwins Dangerous Idea) speaks of biological evolution as an engineering-like process. The making of law for a civilized society seems to proceed in much the same way. It humbles us to think of ourselves as dynam...
