Publications on Macroeconomic models
Working Paper No. 897 | September 2017Ever since the Great Recession, central banks have supplemented their traditional policy tool of setting the short-term interest rate with massive buyouts of assets to extend lines of credit and jolt flagging demand. As with many new policies, there have been a range of reactions from economists, with some extolling quantitative easing’s expansionary virtues and others fearing it might invariably lead to overvaluation of assets, instigating economic instability and bubble behavior. To investigate these theories, we combine elements of the models in chapters 5, 10, and 11 of Godley and Lavoie’s (2007) Monetary Economics with equations for quantitative easing and endogenous bubbles in a new model. By running the model under a variety of parameters, we study the causal links between quantitative easing, asset overvaluation, and macroeconomic performance. Preliminary results suggest that rather than being pro- or countercyclical, quantitative easing acts as a sort of phase shift with respect to time.

Working Paper No. 891 | May 2017
The stock-flow consistent (SFC) modeling approach, grounded in the pioneering work of Wynne Godley and James Tobin in the 1970s, has been adopted by a growing number of researchers in macroeconomics, especially after the publication of Godley and Lavoie (2007), which provided a general framework for the analysis of whole economic systems, and the recognition that macroeconomic models integrating real markets with flow-of-funds analysis had been particularly successful in predicting the Great Recession of 2007–9. We introduce the general features of the SFC approach for a closed economy, showing how the core model has been extended to address issues such as financialization and income distribution. We next discuss the implications of the approach for models of open economies and compare the methodologies adopted in developing SFC empirical models for whole countries. We review the contributions where the SFC approach is being adopted as the macroeconomic closure of microeconomic agent-based models, and how the SFC approach is at the core of new research in ecological macroeconomics. Finally, we discuss the appropriateness of the name “stock-flow consistent” for the class of models we survey.Download:Associated Programs:Author(s):
