I forgot to post my presentation file in the first version of this post. I’ve since edited it, but I know that a lot of people using RSS feeds would not notice the change. So here is the presentation that I gave at that talk to UNEP in November:

Steve, Thanks for the pdf file. I’ve had trouble downloading the ppt files.

Steve, I’ve been looking at TRYM, treasury model at
http://www.treasury.gov.au/documents/238/PDF/trym_m.pdf
They appear to be describing equilibrium models here (block diagrams but no sign of any odes) but produce continuous time simulations over a number of years.
Do you have any idea what’s going on here? Some sort of difference equations approach?

Re #2 CSIRO Addendum
Yes David it’s a very simplistic difference equation system where the future equilibrium of the system is hard wired into it by the assumption that there is a “natural rate of unemployment” which is set at about 5%, and a natural rate of inflation which is set at about 3% (from memory).
You can actually purchase the TRYM model from the ABS (it runs in an econometrics package) and pull it apart. I haven’t yet done so–too damn busy!–but there are comments on TRYM in some of my presentations and I think in a blog entry or two.
