SFC models in Python

Here is a letter from Kenn Tamara, who developed the models in Godley-Lavoie using Python:

I was reading “Monetary Economics” by Godley and Lavoie and came across the sfc-models.net website. I have taken your eViews models and reimplemented them using Python (running the experiments and generating the figures).

Everything is open-source and is written with a package that I developed to help specify and solve the models. The models are implemented as iPython notebooks for easier viewing and can be found at:

Information on the pysolve package used to specify and solve the models can be found at:

(A little warning, the code for pysolve is still under development and there isn’t that much documentation yet)

I hope that the python implementation is useful and would like to contribute it to sfc-models.net.

Thank you,
Kenn Takara

Interactive SFC models

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.

New papers using the SFC approach

Ayoze Alfageme kindly offered to update our references database on publications adopting the stock-flow-consistent approach.
The following is a preliminary list of recent papers, that will soon be included in our database:

Applied Macro-modelling: Fully Scalable models

Winter School on Agent Based and Stock Flow Consistent modelling.

Limerick, January 30th – February 7th

If you are a highly motivated student of economics at masters or Ph.D. level, or you are working with a research center or a public institution and want to spend one week studying, researching, discussing, and exchanging experiences in the nice atmosphere of an Irish University campus nurtured by international experts and fellow students from all around the world, our winter school offers you 7 working days of lectures, seminars, and labs on Stock-Flow Consistent and Agent Based approaches. For more information, see http://s120.ul.ie/drupal/winterSchool and Applied Macro-modelling – Call For Application.

SFC models discussed in Berlin

The annual conference of the Research Network Macroeconomic and Macroeconomic Policies in Berlin had two sessions dedicated to stock-flow models, plus other papers using this approach in other sessions.
The program is available here

Flow of funds at the ECB

This article, “Flow-of-funds analysis at the ECB”, provides an excellent technical description of the European system for flow-of-fund statistics, and some good examples of how they are used at the ECB.
I would recommend it for anyone interesed in anyone doing SFC empirical modeling. It is a pity that the authors have not discovered yet the work of Godley and the book Monetary economics, which is well known at the Bank of England.
