QUESTION NR. 1

Many countries in sub-Saharan Africa have very low labor productivity in many sectors, for example in manufacturing and agriculture. They often despair of even trying to attempt to strengthen their industries unless it is done in an autarkic context, behind protectionist walls. The reason is that they do not believe they can compete with more productive industries abroad'.

Comment this statement, and accurately discuss this issue in the context of the Ricardian model of comparative advantage. Graphical analysis is required to support your answer.
