A spreadsheet version of the IS/MY model (alternative to IS/LM model) — Dirk Ehnts

I hope that this model will be taken up by more colleagues as it is very clear now that the IS/LM model “does not work”. If you make it more realistic by saying that investment does not depend on the rate of interest (vertical IS curve) and that the central bank determines the interest rate (horizontal LM curve), then you will have wasted 3-4 lectures to explain the goods market (IS curve) and the money market (LM curve) only to conclude that both do not matter in practice. It is only a...

Dirk Ehnts — A simple macroeconomic model based on Modern Monetary Theory (and published in 2014 in a peer-reviewed journal

There is a lot of talk about how MMT would lack a “model”. Some commentators on Twitter even claim that MMT would have “no model” and that they just created one themselves. Others believe that stock-flow consistent (SFC) models are basically SFC models. All of that is not quite right! I think that the only model that can really claim to be a “MMT model” is the one I published in a peer-reviewed journal in 2014. The article in the International Journal of Pluralism and Economics Education...

sfc models — New working paper

Modeling economic forces, power relations, and stock-flow consistency:a general constrained dynamics approachby Oliver Richters and Erhard Gloetzl Abstract: In monetary Stock-Flow Consistent (SFC) models, accountingidentities reduce the number of behavioral functions to avoid anoverdetermined system of equations. We relax this restriction using adifferential algebraic equation framework of constrained dynamics.Agents exert forces on the variables according to their desire, forinstance to...

John T. Harvey — Dear President Trump: Your Tax Plan Needs Bigger Deficits!

What I want to highlight here is this: the private sector needs government deficit spending if it is going to recover properly from both the heart attack of the Financial Crisis and the decades of disease brought on by income redistribution and rising debt levels. This is so because government deficits are private-sector surpluses. The logic is really very simple. What number do you get when you add up every trade surplus and trade deficit on the planet? Zero, of course, because one...

Brian Romanchuk — “An Introduction to SFC Models Using Python” Published

Stock-Flow Consistent (SFC) models are a preferred way to present economic models in the post-Keynesian tradition. This book gives an overview of the sfc_models package, which implements SFC models in Python. The approach is novel, in that the user only specifies the high-level parameters of the economic model, and the framework generates and solves the implied equations. The framework is open source, and is aimed at both researchers and those with less experience with economic models. This...

Brian Romanchuk — Kindle Version of SFC Models Book Available…

I just wanted to let everyone know that I have a Kindle edition of the SFC models textbook available. However, the ebook edition is a "textbook" version of the book -- effectively the same thing as a PDF with fixed pages. Not all Kindle readers will support this format (particularly older ones). I believe that the Kindle store will not sell you the book if your reader does not support it, but I suggest caution. I just glanced at the book on my iPad, and it looked OK (which is unsurprising,...
