Harvard CID has just updated its world growth forecast based on complexity. Economic complexity is a metric aimed at measuring the degree of knowledge and technological sophistication of countries. When they are above the GDP level we would expect given its knowledge, it is expected to decelerate. And the other way around. Highlights among the 2015-2025 forecast are India leading growth over the next decade (7.7%), followed by Turkey, Indonesia, Uganda, and Bulgaria. The ranking is much less optimistic on countries like Bangladesh, Cambodia, Iran, Sri Lanka, and Cuba. Between 2005-205, the largest economic complexity (knowledge) loss was registered, sadly and unexpectedly, in Venezuela.
