Abstract: This paper addresses the question of whether a capitalist economy with interest-bearing money can ever sustain a ‘stationary’ (or non-growing) state, or whether, as often claimed, capitalism has an inherent ‘growth imperative’ which arises from the creation of money as interest-bearing debt. We outline the development of a dedicated system dynamics model for describing Financial Assets and Liabilities in a Stock-Flow consistent Framework (FALSTAFF) and use this model to explore the potential for stationary state outcomes in an economy with balanced trade, debt-based money, and private equity. Contrary to claims in the literature, we find that neither credit creation nor the charging of interest on debt create a ‘growth imperative’in and of themselves. We show further that it is possible to move from a growth path towards a stationary state without either crashing the economy or dismantling the system. Our model supports critiques of austerity and underlines the value of countercyclical spending by government. Nonetheless, there remain several good reasons to support the reform of the monetary system.
