Economics values precision and rigour. So surely “doughnut” is a mistake. A doughnut is a torus, but all the diagrams in doughnut economics show an annulus. The torus already has a distinguished place in economics. So wouldn’t it be better to rename the subject Annulus Economics?
Our social system is neither a torus nor an annulus but it does contain a number of circuits. You will find a better diagram of it in my SSRN 2865571 “Einstein’s Criterion Applied to Logically Modelling Macroeconomics”–a short working paper.
