2. Ten years later, Chinese workers have increased their productivity in producing shirts by 50%: each worker can now produce 150 shirts in a year. a. What is the range of prices of computers (in terms of shirts) at which the two countries would trade? In other words, what is the maximum number of shirts that the country importing computers would be willing to exchange for each computer? And what is the lowest number of shirts that the country exporting computers would accept in exchange for each computer? Explain. b. Create a specific numerical example of trade between the two countries. Indicate how many shirts would be exchanged for how many computers (and which country would be trading away which product). Use your production possibilities frontiers to show which country(s) benefit from trade. Note: just to keep things a little simpler, please assume that the US will trade half of what each worker produces. c. How did China’s increased productivity affect the economic well-being of the Chinese? d. How did China’s increased productivity affect the economic well-being of the US?
