Professor Jeff Sachs discusses his new book 'The Ages of Globalization' with Professor Ian Goldin. We are justified to say that we are living through a new age of globalisation, which Professor Jeff Sachs calls the Digital Age. The hugely disruptive changes were already with us before Covid-19, but now we’ve been hurled head-first into the new age. It is marked by enormous geopolitical, technological, and environmental disruptions, posing great risks as well as opportunities. To understand the Digital Age better, it is enormously valuable to gain a historical perspective. Professor Jeff Sachs' new book The Ages of Globalization and this talk, explores the interactions of technology, geography, and institutions throughout human history, describing seven ages of globalisation and the nature of societal change from one age to the next.
