An ecological macro model

The DEFINE (Dynamic Ecosystem-FINance-Economy) model is a stock-flow-fund ecological macroeconomic model that analyses the interactions between the ecosystem, the financial system and the macroeconomy. It aims at examining economic policies and strategies that can allow our societies to live within the biophysical limits of a finite planet.

DEFINE draws on the post-Keynesian and ecological economics tradition. It combines the stock-flow consistent approach developed by Godley and Lavoie with the flow-fund model of Georgescu-Roegen. By doing so it provides an integrated approach to the combined analysis of physical and monetary stocks and flows. The model incorporates explicitly the laws of thermodynamics, the effects of emissions on temperature, climate damages, the waste generation process, the endogeneity of money and the impact of finance on economic activity.

DEFINE produces various scenarios for the future of the ecosystem and the global economy. It is also used to evaluate the effects of various types of environmental policies and strategies, paying particular attention to the role of finance.

The research group of DEFINE consists of:
Dr. Yannis Dafermos
Dr. Giorgos Galanis
Dr. Maria Nikolaidi
