A recent book entitled “Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist” by Kate Raworth of Oxford University’s Environmental Change Institute, offers an alternative to the all too familiar policy of economic growth to solve the issues of poverty, inequality, unemployment in the global economy. Simon Kuznets, who normalised the measurement of economic growth, stated that national income cannot be a accurate measure of total welfare in an economy as it only measures annual flows of money and not stocks of wealth and their distribution. Raworth states that the current model of endless economic growth using up the finite resources of the planet is not the way forward. Most textbooks refer to the circular flow as the model of the economic system – households, firms, banks, overseas markets and the government which bears little relationship to reality today. Instead Raworth goes beyond this simple circular flow model and includes social and environmental issues – energy, the environment, raw materials, water pollution etc.
Raworth’s circular flow consists of two rings – see graphic below.
Inner Ring – this consists of the social foundation and those things we need for a good life – food, water, health, education, peace and justice etc. People living within this ring in the hole in the middle are in a state of deprivation.
Outer Ring – this consists of the earth environmental limits – climate change, ozone depletion, water pollution, loss of species etc.
The area between the two rings is the “ecologically safe and socially just space” in which humanity should strive to live. As stated in The Guardian review, the purpose of economics should be to help us enter that space and stay there. As the graphic shows we breach both rings as billions of people live below the poverty line and climate conditions, biodiversity loss, land conversion etc are at concerning levels. The video below is a useful explanation.
