Economic importance of China: How important would an economic downturn in China be for the United States? Paul Krugman reviews some of the reasons why the United States perhaps shouldn’t worry too much...
I’ve long believed that to understand business cycles we need to consider not just net flows but also gross interdependencies. A downturn in China will affect some businesses much more than others. If specialized labor and capital do not easily move to other sectors, that can end up having significant multiplier effects.
For example, while China may only account for 15% of world GDP, it has been a huge factor in commodity markets over the last decade. ... Of course, lower commodity prices [from the slowdown in China] will force layoffs for oil companies and miners but leave more money in the hands of consumers. However, additional spending from that channel has been more modest than many of us were anticipating.
Another concern comes from financial linkages. A Chinese downturn will unquestionably be a big hit for certain financial institutions. Exactly who those will be and what it means for the rest of us, I don’t know. As Warren Buffett observed, “you only find out who is swimming naked when the tide goes out.”
The bottom line is that an economic slowdown in China already is a very big deal for some U.S. workers and businesses. I don’t know what the ultimate implications for the U.S. of a significant recession in China would be.
But things I don’t know cause me to worry.
