Talk at https://www.ppe-conference.org/home/ on 7 April 2018: Starting out as a fringe movement almost 15 years ago, décroissance and its associated notions of degrowth and postgrowth have made inroads into both civil society as well as heterodox economics. Today we can observe a diversity of perspectives within the degrowth movement, that share certain core assumptions – namely the criticism of the fixation on economic growth, its measurement through GDP and exclusion of alternative understandings of well-being, as well as the absolute limits on economic activities imposed by a finite planet –, but differ in their economic analyses and policy suggestions. Conservative, social-reformist, sufficiency-oriented, anti-capitalist and feminist degrowth perspectives can be identified in the current discourse. This contribution seeks to find the connecting tissues beyond the core assumptions in order to outline a political economy of postgrowth. This new form of "PPE" (postgrowth political economy) will then be firmly placed in the specific German economic tradition of ordoliberalism. In fact, it will be argued that postgrowth economics constitutes the 21st century successor to ordoliberalism under the conditions of economic abundance, social inequality and ecological scarcity.
