This working paper presents a stock-flow consistent (SFC) simulation model of a national economy, calibrated on the basis of Canadian data. LowGrow SFC describes the evolution of the Canadian economy in terms of six financial sectors whose behaviour is based on ‘stylised facts’ in the Post-Keynesian tradition. A key feature of the model is its ability to provide a systematic account, not only of economic and financial variables, but also of key environmental and social dimensions of the economy. In particular, it tracks the evolution of carbon emissions and the distribution of incomes over time, under various policy assumptions.
