Asjad Naqvi has developed the Mathematica code for most Godley-Lavoie models, and put them up so that they can be used interactively.
I recently discovered that Kevin W. Capehart has written a piece of code in Mathematica from one of my Eviews files for the Godley – Lavoie Monetary economics book, and turned it into a CDF, to illustrate the paradox of thrift
To run the simulation you need to install the free Wolfram reader, and activate it.
This little tool is potentially very useful in exploring stock-flow models, which are tipically non linear, and therefore difficult to solve analitically. Creating a nice interface which allows the user to check model responses to different values of parameters and exogenous variables could help find the range of parameter values for which the model is producing stable (or unstable etc) solutions.
