US capital inflows target non-tradable sectors, depressing tradable sectors & slowing US innovation, according to @MartinWolf Working Paper. This dynamic creates a feedback loop where reduced innovation in the US leads to slower global growth.

New paper (model based ) that attempts to connect the global saving glut and productivity growth. Worth noting in the model innovation by US firms pushes the world technological frontier. Other countries grow by absorbing knowledge from the US. Those are the only two agents.



Ed Comment:Add to data base. Interesting idea but it seems a bit outdated. The savings glut definitely shifts the US economy from manufacturing to the non-tradable domestic service sectors where productivity growth has been slower, albeit where US productivity is higher than the rest of the world’s. $3 an hour offshore wages put enormous pressure on domestic manufacturing, which was forced to selectively prune off low-productivity production, and which has accelerated productivity growth in the remaining manufacturing sectors beyond growth in the demand for manufactured goods, which hollows out manufacturing employment and drives talent into other sectors with more promising career opportunities, especially when big legacy pensions that can no longer by paid with declining domestic demand, employment, and profit margins “bankrupts” large collective enterprises needed for manufacturing. America never abandoned the technological frontier. Unlike Europe and Japan, America, out of necessity, abandoned the manufacturing technological frontier and shifted its talent to IT, which fortunately proved to be more valuable than the old manufacturing frontier, especially given the interlocking developments described above, although it was probably more valuable regardless of these developments but without them, we might have been slow to make the shift, like Europe and Japan. Not only has the future of IT proven to be more promising relative to manufacturing, it reduces the importance of capital relative to talent/ideas, and makes it easier to make and measure individual contributions by talent (which are power law distributed)—good dynamics for talent, especially when there is a shortage of talent. (My chapter made these points, but Diana insisted on taking them out because she misguidedly insisted on defending the success of domestic manufacturing and, oddly, couldn’t accept these points because of her agenda.) Sorry for the run on sentences.
The key feature is that sectors producing tradable goods are the engine of growth. Capital flows from the chronic surplus countries to the US boost demand for our non-tradable sectors/goods (construction), and depress economic activity in the US tradable sectors (manufacturing). The result is lower investment in innovation by US firms. Since US innovation determines the world technological frontier, global growth slows down. Effect similar to natural resource curse, but financial and global in nature. Hence, we dub it the global financial resource curse.
"...Since the late 1990s, the United States has received large capital flows from developing countries - a phenomenon known as the global saving glut - and experienced a productivity growth slowdown. Motivated by these facts, we provide a model connecting international financial integration and global productivity growth. The key feature is that the tradable sector is the engine of growth of the economy. Capital flows from developing countries to the United States boost demand for U.S. non-tradable goods, inducing a reallocation of U.S. economic activity from the tradable sector to the non-tradable one.In turn, lower profits in the tradable sector lead firms to cut back investment in innovation. Since innovation in the United States determines the evolution of the world technological frontier, the result is a drop in global productivity growth. This effect, which we dub the global financial resource curse, can help explain why the global saving glut has been accompanied by subdued investment and growth, in spite of low global interest rates..."
