MILAN – Digital technologies are once again transforming global value chains and, with them, the structure of the global economy. What do businesses, citizens, and policymakers need to know as they scramble to keep up?
Digitally enabled supply chains initially increased efficiency and dramatically shortened lead times. Capital was mobile; labor less so. Economic activity (production, research, design, etc.) moved to any accessible country or region that had relatively inexpensive labor and human capital. With only a slight lag, complexity became manageable, and global supply chains’ linear model (something produced in country A is consumed in country B) gave way to a more complex model with more fragmented but more efficient supply networks.
