generation productivity parameter, z. At the beginning, time 0, the rich country
has more knowledge stock than the poor one, Ar0 > Ap0, where subscript labels
time and superscript labels country being rich or poor. However, the fraction
of researchers in poor country is larger than the one in rich country, ̄lp > ̄lr .
Question 4 Part a
In which country, would you prefer to live in the short-run? How about in the
long-run?
How long would it take for the poor country to reach rich one’s per capita
output level? Show your results analytically and graphically as well. (If you pre-
fer solving this question numerically by assigning values to the above parameters
and variables, feel free to do so
