The chapter's point of departure is that failures to address collective action problems, such as those of the G20, are invariably moral failures. To tackle these moral failures, it is necessary to measure prosperity in ways that reflect our moral values. The chapter proposes that the G20 adopts the SAGE dashboard for this purpose, where S measures solidarity, A stands for agency, G is material gain and E represents environmental sustainability. On this basis, it is possible to design a normative accounting framework for international, national and corporate accounts (INCAs) for public and private sectors. This is a first step towards “moral capitalism.”
