The “Mun” iteration of Minsky, the Open Source system dynamics program with special features to handle monetary modeling, is now available at SourceForge:
The program now supports the basic features needed for system dynamics in general, and has the added capability of modeling financial flows using “Godley Tables”, which are based on the double-entry bookkeeping standards of accountants and make it easy to generate dynamic (ordinary differential) equations of financial flows.
Thanks are due to the Institute for New Economic Thinking (INET) which provided the initial funding that enabled the project to start, and to the donors via Kickstarter who provided additional funds that enabled this rather more polished version to be developed.
There is still a lot to do.
Many existing features (such as grouping) require additional refinement, and many additional features are needed–such as allowing direct entry of equations, and adding Stock-Flow Consistent modeling techniques in addition to the double-entry bookkeeping checks that Godley Tables already offer. We also only have an incomplete help file, though that will be improved over the next couple of months.
The program at present does not support multisectoral analysis, and is only suitable for modeling a single economy (or the abstraction of a single global economy). These two extensions are planned, and will of course require additional funding which I will seek in the future.
But for now it works very well as a free tool for system dynamics in general, and a specialized tool for monetary macroeconomic modeling in particular. Please give it a workout.
