The “software” that structures our financial systems and, through them, the broader economy, is made up of certain basic concepts that guide how we think. These concepts include money, finance, investment, credit, and - above all - capital. This conceptual software manifests itself in our current “operating system” of institutions and practices. But our concepts and the system itself are radically out of date as representations of monetary, financial, productive and distributive reality. Robert Hockett shows that this mismatch has serious consequences and argues that it’s time for a complete overhaul of our economic understanding.
