Book excerpt: This report is about a huge contribution to our deepening understanding of what the global economy really means and how it is changing. The report helpfully distinguishes elements of an economy that are tradable and the large set that are non-tradable. Clearly the tradables set is expanding with the support of enabling technology. The report argues that connectivity in the networks that define the evolving architecture of GVCs is important. This Global Value Chain Development Report is the result of intensive and detailed work in assembling and analyzing data on the structure of economies and on how they are linked. It creates a much clearer picture of evolving patterns of independence. It also presents a much clearer picture of comparative advantage. --Publisher description.
