economists have had an enormous impact on trade policy, and they provide a strong rationale for free trade and for removal of trade barriers.   although the objective of a trade agreement is to liberalize trade, the actual provisions are heavily shaped by domestic and international political realities.   the world has changed enormously from the time when david ricardo proposed the law of comparative advantage, and in recent decades economists have modified their theories to account for trade in factors of production, such as capital and labor, the growth of supply chains that today dominate much of world trade, and the success of neomercantilist countries in achieving rapid growth.

almost all western economists today believe in the desirability of free trade, and this is the philosophy advocated by international institutions such as the world bank, the international monetary fund, and the world trade organization (wto).   and this was the view after world war ii, when western leaders launched the general agreement on tariffs and trade (gatt) in 1947.

however, economic theory has evolved substantially since the time of adam smith, and it has evolved rapidly since the gatt was founded.   to understand u.s. trade agreements and how they should proceed in the future, it is important to review economic theory and see how it has evolved and where it is today.

in the seventeenth and eighteenth centuries, the predominant thinking was that a successful nation should export more than it imports and that the trade surplus should be used to expand the nation’s treasure, primarily gold and silver. this would allow the country to have a bigger and more powerful army and navy and more colonies.

one of the better-known advocates of this philosophy, known as mercantilism, was thomas mun, a director of the british east india company.   in a letter written in the 1630s to his son, he said: “the ordinary means therefore to increase our wealth and treasure is by foreign trade, wherein wee must ever observe this rule; to sell more to strangers yearly than wee consume of theirs in value. . by this order duly kept in our trading, . . that part of our stock which is not returned to us in wares must necessarily be brought home in treasure.”[1]

mercantilists believed that governments should promote exports and that governments should control economic activity and place restrictions on imports if needed to ensure an export surplus. obviously, not all nations could have an export surplus, but mercantilists believed this was the goal and that successful nations would gain at the expense of those less successful.   ideally, a nation would export finished goods and import raw materials, under mercantilist theory, thereby maximizing domestic employment.

then adam smith challenged this prevailing thinking in the wealth of nations published in 1776.[2]   smith argued that when one nation is more efficient than another country in producing a product, while the other nation is more efficient at producing another product, then both nations could benefit through trade. this would enable each nation to specialize in producing the product where it had an absolute advantage, and thereby increase total production over what it would be without trade. this insight implied very different policies than mercantilism. it implied less government involvement in the economy and a reduction of barriers to trade.

the theory of comparative advantage

thirty-one years after the wealth of nations was published, david ricardo introduced an extremely important modification to the theory in his on the principles of political economy and taxation, published in 1817.[3]   ricardo observed that trade will occur between nations even where one country has an absolute advantage in producing all the products traded.

ricardo showed that what was important was the comparative advantage of each nation in production. the theory of comparative advantage holds that even if one nation can produce all goods more cheaply than can another nation, both nations can still trade under conditions where each benefits. under this theory, what matters is relative efficiency.

economists sometimes compare this to the situation where even though a lawyer might be more proficient at both law and typing than the secretary, it would still pay the lawyer to have the secretary handle the typing to allow more time for the higher-paying legal work. similarly, if each country specializes in the products where it is comparatively more efficient, total production will be higher and consumers will have more goods to utilize.
