Lecture Outline and Notes:
I. Explaining Trade: International Trade Theory
International trade is large in volume and growing, and is also critical to the economic
performance of most nations. International trade theory attempts to answer the question,
“Why does this trade occur, both overall and between particular nations?”
A. Mercantilism
1. One of the first economic doctrines.
2. Central idea–precious metals were viewed as the only source of wealth and nations
could accumulate these precious metals by exporting more goods than they import.
3. Governments should control foreign trade to ensure a favorable trade balance.
B. Theory of Absolute Advantage
1. Adam Smith (The Wealth of Nations – 1776) attacked mercantilism and said that to
trade in order to accumulate gold and other precious metals was foolish. By means of
free, unregulated trade, a nation could acquire what it did not produce.
2. He stated that a nation should produce only those goods in which it was most efficient
(country specialization). The surplus could be traded to obtain the products that could
not be produced advantageously.
3. Ask: “What are the limits within which both countries are willing to trade?” Discuss
Specialization and Trade to further explain Absolute Advantage Theory.
4. Use the examples in the text to explain Absolute Advantage Theory in depth.
1. David Ricardo (1817) showed that if a nation were less efficient in the production of
efficient in the production of both goods.
2. Smith’s and Ricardo’s theories considered labor as the only important factor in
calculating production costs and no thought was given to the possibility of producing
the same goods with different combinations of factors.
3. Use the examples in the text to explain Absolute Advantage Theory in depth.
1. Traders must know a price in domestic currency to determine if is better to produce
2. Exchange rate is the price of one currency stated in terms of the other.
3. Countries can regain a competitive position through currency devaluation.
