Globalization is frequently associated with comparative advantage and:
a.  Increased specialization.
b.  Decreased specialization.
c.   Maintenance of global economic balance of power.
d.   Elimination of tariffs.
Answer:A
Choice "a" is correct. A global economy with increased economies of scale will likely result in increased specialization in individual economies.
Choice "b" is incorrect. A global economy will likely promote increased economies of scale and increased, not decreased, specialization.
Choice "c" is incorrect. Globalization put economic activity between nations in play and will likely result in shifts rather than maintenance of the economic balance of power. Choice "d" is incorrect. Globalization does not result in elimination of tariffs. Globalization and competition may even motivate governments to adopt protective barriers such as tariffs to protect local economies.
