Do foreign capital inflows slow U.S. productivity growth?
Core argument: U.S. investment has been weak and productivity growth has slowed since the early 2000s, contrary to the expectation that capital inflows raise productivity.
Despite expectations that capital inflows boost productivity, data shows that since the early 2000s, U.S. investment has been weak and productivity growth has slowed. Capital inflows from developing countries have shifted U.S. economic activity from the tradable sector, the engine of growth, to the non-tradable sector, leading to reduced profits and innovation investment in tradables. This reallocation results in a slowdown in U.S. productivity growth, which, as the technological leader, impacts global growth. The phenomenon, termed the global financial resource curse, highlights how cheap capital inflows can paradoxically depress productivity growth by financing a boom in the non-tradable sector, ultimately slowing global productivity growth.
