Conditions for a post-growth economy from Post-Keynesian perspectives
Authors: Steffen Lange
Abstract: The paper investigates under what conditions an economy generates constant production levels. Prominent Post-Keynesian macroeconomic theories are used to examine this question theoretically. The mechanisms responsible for growth vary between different types of Post-Keynesian theories. This variety is used in order to develop an understanding of the diversity of conditions that are necessary for a post-growth economy to be stable. Central to the analysis are: the size and composition of government expenditures; technological progress and the marginal productivity of capital; taxation policies; the distribution of income and the composition of consumption; and the dominant type of business ownership in the economy.
Investigating Pathways To Post-growth Economies Through Prospective Macroeconomic Modeling: Visions and Scenarios for France
Authors: François Briens, Nadia Maïzi
Abstract: An important theorization effort has been made in recent years in the field of degrowth and post-growth economics. Yet current literature still falls a bit short of providing detailed investigations of possible macro-socioeconomic and biophysical outcomes that may result from taking in such paths. Using a dynamic input-output simulation model of the French monetary economy, we explore different scenarios of transition towards post-growth societies. These scenarios seek to reflect contrasted “visions of sustainable societies and lifestyles”, inferred from a survey conducted amongst different social groups – including in particular actors within the Degrowth movement. They involve structural and behavioral changes in consumption patterns, and integrate proposals and strategies issued from the Degrowth movement. We investigate the possible outcomes of these scenarios in terms of employment, poverty, public debt, energy consumption, waste and GHG emissions and discuss the potential strengths and weaknesses of the different visions they reflect.
Tracking physical stocks, material/energy flows and the scale of economies: A case study of Canada and Spain (1995-2009) - methodology and preliminary results
Authors: Andrew L Fanning, Dan O’Neill
Abstract: This paper will report results of a 3-year research project (2013-2016) that aims to construct a time series of biophysical and social accounts at national and sub-national levels for Canada and Spain. The focus here will be on biophysical accounts that aim to inform the following central issue in ecological economics: how do we measure national (or sub-national) economies’ movement towards, or away from, a steady state economy (SSE)? The main contribution of this research will be to compile national accounts for Canada and Spain and two sub-national regions that will be suitable for cross-country comparison of physical stocks, flows and scale of economic activities over a 15-year time period (1995-2009). Significant limitations of the methodologies utilized exist and will be discussed critically. Despite limitations, this information is important because it provides an indication of whether physical degrowth is needed for these economies and if so, most importantly, how much?
