Technology as a Source of Comparative Advantage: The Product Cycle Theory
108. Explain how immigration and trade may worsen wage inequality, and how college education may mitigate against
that.
Trade tends to increase the demand for skilled workers relative to unskilled workers, thus
worsening wage inequality. Immigration of unskilled workers decreases the supply of skilled
workers relative to unskilled workers, thus worsening wage inequality. Alternatively, college
education increases the supply of skilled workers relative to unskilled workers, thus reducing
wage inequality.

109. How does Staffan Linder explain world trade patterns?
Linder offers two explanations of world trade patterns. Trade in primary products conforms
well to the factor-endowment theory. However, trade in manufactured goods is best explained
by overlapping demand structures among nations. For manufactured goods, the basis for trade
is stronger when the structure of demand in two nations is more similar, due to similar per-
capita incomes.
