D. Graph the labor productivity functions for each country on the graph below. Include all relevant information
from A-C above, and label your graph carefully (need not be to scale).
E. If the MPK for Argentina converges to the MPK for Spain, calculate the new level of k in Argentina. Explain
whether labor productivity and the capital-labor ratio will also converge.
