1. Convergence requires diffusion.
a. What might be the challenges to
diffusing technologies across national
boundaries, as compared to diffusing
technologies across regions within a
country? Discuss.
b. Do these challenges depend upon the
populations of the countries from which
innovations originate and of the countries
to which they are diffusing? If yes, how? If
no, why not?
c. What does your answer to question 2
imply about whether international
inequality is better assessed by simply
comparing average incomes across
countries (concept 1 inequality), or by
weighting them with national populations
(concept 2 inequality)? Explain.
