Summary

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.

The working paper describes in detail the structure of the model, its behavioural assumptions and the calibration of its variables and parameters. It develops two new performance indicators to track the progress of the economy: an environmental burden index (EBI) to describe the environmental performance of the model; and a composite sustainable prosperity index (SPI) based on a weighted average of seven economic, social and environmental performance indicators.

We use the model to generate three very different stories about the future of the Canadian economy, covering the half century from 2017 to 2067: a Base Case in which current trends and relationships are projected into the future, a Carbon Reduction Scenario in which measures are introduced specifically designed to reduce greenhouse gas emissions, and a Sustainable Prosperity Scenario which incorporates additional measures to improve environmental, social and financial conditions across society.

Only in this third scenario, with its much slower rate of economic growth, do we see an overall improvement in performance as indicated by the SPI. Contrary to the accepted wisdom, the results indicate the feasibility of improved environmental and social outcomes, even as the growth rate declines to zero.

This paper presents a stock-flow consistent (SFC) macroeconomic simulation model for Canada. Contrary to the widely accepted view, the results suggest that ‘green growth’ (in the Carbon Reduction Scenario) may be slower than ‘brown growth’. More importantly, we show (in the Sustainable Prosperity Scenario) that improved environmental and social outcomes are possible even as the growth rate declines to zero.

Taken together, the suite of system dynamics models developed by Tim Jackson et al represent the first steps in constructing a new macro-economic synthesis capable of exploring the economic and financial dimensions of an economy confronting resource or environmental constraints.

Sluggish recovery in the wake of the financial crisis has revived discussion of a ‘secular stagnation’. These conditions have been blamed for rising inequality and political instability. Tim Jackson contests this view, pointing instead to a steadfast refusal to address the ‘post-growth challenge’. (An earlier draft of the article was published as CUSP Working Paper No 12.)

Revised second edition of Peter Victor's influential book. Human economies are overwhelming the regenerative capacity of the planet, this book explains why long-term economic growth is infeasible, and why, especially in advanced economies, it is also undesirable. Simulations developed with Tim Jackson, show that managing without growth is a better alternative.

The publication of Prosperity without Growth was a landmark in the sustainability debate. This substantially revised and re-written edition updates its arguments and considerably expands upon them. Tim Jackson demonstrates that building a ‘post-growth’ economy is not Utopia—it's a precise, definable and meaningful task. It’s about taking simple steps towards an economics fit for purpose.
