For the period 1980-2010, how did the rate of growth of per capita GDP in China compare to that in the US? How did the rate of growth of technological improvement (broadly conceived) in the two countries compare? Give some examples of changes that caused technology (broadly conceived) in China to rise during this period. Over the next half century, do you expect the rate of technological improvement (broadly conceived) in the two countries to become more similar or more different (relative to 1980-2010)? Why?
