The Theory of Comparative Advantage
The International Economics Study Center ^ | Unknown | Steven Suranovic

Posted on 03/19/2004 7:54:53 PM PST by Luis Gonzalez

The theory of comparative advantage is perhaps the most important concept in international trade theory. It is also one of the most commonly misunderstood principles. There is a popular story told amongst economists that once when an economics skeptic asked Paul Samuelson (a Nobel laureate in economics) to provide a meaningful and non-trivial result from the economics discipline, Samuelson quickly responded with, "comparative advantage."

The sources of the misunderstandings are easy to identify. First, the principle of comparative advantage is clearly counter-intuitive. Many results from the formal model are contrary to simple logic. Secondly, the theory is easy to confuse with another notion about advantageous trade, known in trade theory as the theory of absolute advantage. The logic behind absolute advantage is quite intuitive. This confusion between these two concepts leads many people to think that they understand comparative advantage when in fact, what they understand, is absolute advantage. Finally, the theory of comparative advantage is all too often presented only in its mathematical form. Using numerical examples or diagrammatic representations are extremely useful in demonstrating the basic results and the deeper implications of the theory. However, it is also easy to see the results mathematically, without ever understanding the basic intuition of the theory.

The early logic that free trade could be advantageous for countries was based on the concept of absolute advantages in production. Adam Smith wrote in The Wealth of Nations,

"If a foreign country can supply us with a commodity cheaper than we ourselves can make it, better buy it of them with some part of the produce of our own industry, employed in a way in which we have some advantage. " (Book IV, Section ii, 12)

The idea here is simple and intuitive. If our country can produce some set of goods at lower cost than a foreign country, and if the foreign country can produce some other set of goods at a lower cost than we can produce them, then clearly it would be best for us to trade our relatively cheaper goods for their relatively cheaper goods. In this way both countries may gain from trade.

The original idea of comparative advantage dates to the early part of the 19th century. Although the model describing the theory is commonly referred to as the "Ricardian model", the original description of the idea can be found in an Essay on the External Corn Trade by Robert Torrens in 1815. David Ricardo formalized the idea using a compelling, yet simple, numerical example in his 1817 book titled, On the Principles of Political Economy and Taxation. The idea appeared again in James Mill's Elements of Political Economy in 1821. Finally, the concept became a key feature of international political economy upon the publication of Principles of Political Economy by John Stuart Mill in 1848.(1)

David Ricardo's Numerical Example

Because the idea of comparative advantage is not immediately intuitive, the best way of presenting it seems to be with an explicit numerical example as provided by David Ricardo. Indeed some variation of Ricardo's example lives on in most international trade textbooks today. (See page 40-5 in this text)

In his example Ricardo imagined two countries, England and Portugal producing two goods, cloth and wine, using labor as the sole input in production. He assumed that the productivity of labor (i.e., the quantity of output produced per worker) varied between industries and across countries. However, instead of assuming, as Adam Smith did, that England is more productive in producing one good and Portugal is more productive in the other; Ricardo assumed that Portugal was more productive in both goods. Based on Smith's intuition, then, it would seem that trade could not be advantageous, at least for England.

However, Ricardo demonstrated numerically that if England specialized in producing one of the two goods, and if Portugal produced the other, then total world output of both goods could rise! If an appropriate terms of trade (i.e., amount of one good traded for another) were then chosen, both countries could end up with more of both goods after specialization and free trade then they each had before trade. This means that England may nevertheless benefit from free trade even though it is assumed to be technologically inferior to Portugal in the production of everything,.

As it turned out, specialization in any good would not suffice to guarantee the improvement in world output. Only one of the goods would work. Ricardo showed that the specialization good in each country should be that good in which the country had a comparative advantage in production. To identify a country's comparative advantage good requires a comparison of production costs across countries. However, one does not compare the monetary costs of production or even the resource costs (labor needed per unit of output) of production. Instead one must compare the opportunity costs of producing goods across countries.

A country is said to have a comparative advantage in the production of a good (say cloth) if it can produce cloth at a lower opportunity cost than another country. The opportunity cost of cloth production is defined as the amount of wine that must be given up in order to produce one more unit of cloth. Thus England would have the comparative advantage in cloth production relative to Portugal if it must give up less wine to produce another unit of cloth than the amount of wine that Portugal would have to give up to produce another unit of cloth.

All in all, this condition is rather confusing. Suffice it to say, that it is quite possible, indeed likely, that although England may be less productive in producing both goods relative to Portugal, it will nonetheless have a comparative advantage in the production of one of the two goods. Indeed there is only one circumstance in which England would not have a comparative advantage in either good, and in this case Portugal also would not have a comparative advantage in either good. In other words, either each country has the comparative advantage in one of the two goods or neither country has a comparative advantage in anything.

Another way to define comparative advantage is by comparing productivities across industries and countries. Thus suppose, as before, that Portugal is more productive than England in the production of both cloth and wine. If Portugal is twice as productive in cloth production relative to England but three times as productive in wine, then Portugal's comparative advantage is in wine, the good in which its productivity advantage is greatest. Similarly, England's comparative advantage good is cloth, the good in which its productivity disadvantage is least. This implies that to benefit from specialization and free trade, Portugal should specialize and trade the good in which it is "most best" at producing, while England should specialize and trade the good in which it is "least worse" at producing.

Note that trade based on comparative does not contradict Adam Smith's notion of advantageous trade based on absolute advantage. If as in Smith's example, England were more productive in cloth production and Portugal were more productive in wine, then by we would say that England has an absolute advantage in cloth production while Portugal has an absolute advantage in wine. If we calculated comparative advantages, then England would also have the comparative advantage in cloth and Portugal would have the comparative advantage in wine. In this case, gains from trade could be realized if both countries specialized in their comparative, and absolute, advantage goods. Advantageous trade based on comparative advantage, then, covers a larger set of circumstances while still including the case of absolute advantage and hence is a more general theory.

The Ricardian Model - Assumptions and Results

The modern version of the Ricardian model and its results are typically presented by constructing and analyzing an economic model of an international economy. In its most simple form the model assumes two countries producing two goods using labor as the only factor of production. Goods are assumed homogeneous (identical) across firms and countries. Labor is homogeneous within a country but heterogeneous (non-identical) across countries. Goods can be transported costlessly between countries. Labor can be reallocated costlessly between industries within a country but cannot move between countries. Labor is always fully employed. Production technology differences across industries and across countries and are reflected in labor productivity parameters. The labor and goods markets are assumed to be perfectly competitive in both countries. Firms are assumed to maximize profit while consumers (workers) are assumed to maximize utility. (See page 40-2 for a more complete description)

The primary issue in the analysis of this model is what happens when each country moves from autarky (no trade) to free trade with the other country. In other words what are the effects of trade. The main things we care about are trade's effects on the prices of the goods in each country, the production levels of the goods, employment levels in each industry, the pattern of trade (who exports and who imports what), consumption levels in each country, wages and incomes, and the welfare effects both nationally and individually.

Using the model one can show that, in autarky, each country will produce some of each good. Because of the technology differences, relative prices of the two goods will differ between countries. The price of each country's comparative advantage good will be lower than the price of the same good in the other country. If one country has an absolute advantage in the production of both goods (as assumed by Ricardo) then real wages of workers (i.e., the purchasing power of wages) in that country will be higher in both industries compared to wages in the other country. In other words, workers in the technologically advanced country would enjoy a higher standard of living than in the technologically inferior country. The reason for this is that wages are based on productivity, thus in the country that is more productive, workers get higher wages.

The next step in the analysis is to assume that trade between countries is suddenly liberalized and made free. The initial differences in relative prices of the goods between countries in autarky will stimulate trade between the countries. Since the differences in prices arise directly out of differences in technology between countries, it is the differences in technology that cause trade in the model. Profit-seeking firms in each country's comparative advantage industry would recognize that the price of their good is higher in the other country. Since transportation costs are zero, more profit can be made through export than with sales domestically. Thus each country would export the good in which they have a comparative advantage. Trade flows would increase until the price of each good is equal across countries. In the end, the price of each country's export good (its comparative advantage good) will rise and the price of its import good (its comparative disadvantage good) will fall.

The higher price received for each country's comparative advantage good would lead each country to specialize in that good. To accomplish this, labor would have to move from the comparative disadvantaged industry into the comparative advantage industry. This implies that one industry goes out of business in each country. However, because the model assumes full employment and costless mobility of labor, all of these workers are immediately gainfully employed in the other industry.

One striking result here is that even when one country is technologically superior to the other in both industries, one of these industries would go out of business when opening to free trade. Thus, technological superiority is not enough to guarantee continued production of a good in free trade. A country must have a comparative advantage in production of a good, rather than an absolute advantage, to guarantee continued production in free trade. From the perspective of a less developed country, the developed countries' superior technology need not imply that LDC industries cannot compete in international markets.

Another striking result is that the technologically superior country's comparative advantage industry survives while the same industry disappears in the other country, even though the workers in the other country's industry has lower wages. In other words, low wages in another country in a particular industry is not sufficient information to know which country's industry would perish under free trade. From the perspective of a developed country, freer trade may not result in a domestic industry's decline just because the foreign firms pay their workers lower wages.

The movement to free trade generates an improvement in welfare in both countries both individually and nationally. Specialization and trade will increase the set of consumption possibilities, compared with autarky, and will make possible an increase in consumption of both goods, nationally. These aggregate gains are often described as improvements in production and consumption efficiency. Free trade raises aggregate world production efficiency because more of both goods are likely to be produced with the same number of workers. Free trade also improves aggregate consumption efficiency, which implies that consumers have a more pleasing set of choices and prices available to them.

Real wages (and incomes) of individual workers are also shown to rise in both countries. Thus, every worker can consume more of both goods in free trade compared with autarky. In short, everybody benefits from free trade in both countries. In the Ricardian model trade is truly a win-win situation.

Defending Against Skeptics:
The True Meaning and Intuition of the Theory of Comparative Advantage

Many people who learn about the theory of comparative advantage quickly convince themselves that its ability to describe the real world is extremely limited, if not, non-existent. Although the results follow logically from the assumptions, the assumptions are easily assailed as unrealistic. For example, the model assumes only two countries producing two goods using just one factor of production. There is no capital or land or other resources needed for production. The real world, on the other hand, consists of many countries producing many goods using many factors of production. Each market is assumed to be perfectly competitive, when in reality there are many industries in which firms have market power. Labor productivity is assumed fixed, when in actuality it changes over time, perhaps based on past production levels. Full employment is assumed, when clearly workers cannot be immediately and costlessly moved to other industries. Also, all workers are assumed identical. This means that when a worker is moved from one industry to another, he or she is immediately as productive as every other worker who was previously employed there. Finally, the model assumes that technology differences are the only differences that exist between the countries.

With so many unrealistic assumptions it is difficult for some people to accept the conclusions of the model with any confidence, especially when so many of the results are counterintuitive. Indeed one of the most difficult aspects of economic analysis is how to interpret the conclusions of models. Models are, by their nature, simplifications of the real world and thus all economic models contain unrealistic assumptions. Therefore, to dismiss the results of economic analysis on the basis of unrealistic assumptions means that one must dismiss all insights contained within the entire economics discipline. Surely, this is not practical or realistic. Economic models in general and the Ricardian model in particular do contain insights that most likely carry over to the more complex real world. The following story is meant to explain some of the insights within the theory of comparative advantage by placing the model into a more familiar setting.

A Gardening Story

Suppose it is early spring and it is time to prepare the family backyard garden for the first planting of the year. The father in the household sets aside one Sunday afternoon to do the job but hopes to complete the job as quickly as possible. Preparation of the garden requires the following tasks. First, the soil must be turned over and broken up using the roto-tiller, then the soil must be raked and smoothed. Finally, seeds must be planted or sowed.

This year the father's seven year old son is anxious to help. The question at hand is whether the son should be allowed to help if one's only objective is to complete the task in the shortest amount of time possible.

At first thought, the father is reluctant to accept help. Clearly each task would take the father less time to complete than the time it would take the son. In other words, the father can perform each task more efficiently than the seven year old son. The father estimates that it will take him three hours to prepare the garden if he works alone, as shown in the following table.

Task Completion Time (hours)
Roto-Tilling 1.0
Raking 1.0
Planting 1.0
Total 3.0

On second thought, the father decides to let his son help according to the following procedure. First the father begins the roto-tilling. Once he has completed half of the garden, the son begins raking the roto-tilled section while the father finishes roto-tilling the rest of the garden plot. After the father finishes roto-tilling he begins planting seeds in the section the son has already raked. Suppose the son rakes slower than the father plants, and that the father completes the sowing process just as the son finishes raking. Note this implies that raking takes the son almost 2 hours compared to one hour for the father. However, because the son's work is done simultaneously with the father's work, it does not add to the total time for the project. Under this plan the time needed to complete the tasks in shown in the following table.

Task Completion Time (hours)
Roto-Tilling 1.0
Raking & Planting 1.0
Total 2.0

Notice that the total time needed to prepare the garden has fallen from 3 hours to 2 hours. The garden is prepared in less time with the son's help than it could have been done independently by the father. In other words, it makes sense to employ the son in (garden) production even though the son is less efficient than the dad in every one of the three required tasks. Overall efficiency is enhanced when both resources (the father and son) are fully employed.

This arrangement also clearly benefits both the father and son. The father completes the task in less time and thus winds up with some additional leisure time which the father and son can enjoy together. The son also benefits because he has contributed his skills to a productive activity and will enjoy a sense of accomplishment. Thus both parties benefit from the arrangement.

However, it is important to allocate the tasks correctly between the father and the son. Suppose the father allowed his son to do the roto-tilling instead. In this case the time needed for each task might look as follows.

Task Completion Time (hours)
Roto-Tilling 4.0
Raking 1.0
Planting 1.0
Total 6.0

The time needed for roto-tilling has now jumped to 4 hours because we have included the time spent traveling to and from the hospital and the time spent in the emergency room! Once the father and son return, the father must complete the remaining tasks on his own. Overall efficiency declines in this case compared to the father acting alone.

This highlights the importance of specializing in production of the task in which you have a comparative advantage. Even though the father can complete all three tasks quicker than his son, his relative advantage in roto-tilling greatly exceeds his advantage in raking and planting. One might say that the father is most-best at roto-tilling while he is least-best at raking and planting. On the other hand, the son is least-worse at raking and planting but most-worse at roto-tilling. Finally, because of the sequential nature of the tasks, the son can remain fully employed only if he works on the middle task, namely raking.

Interpreting the Theory of Comparative Advantage

The garden story offers an intuitive explanation for the theory of comparative advantage and also provides a useful way of interpreting the model results. The usual way of stating the Ricardian model results is to say that countries will specialize in their comparative advantage good and trade them to the other country such that everyone in both countries benefit. Stated this way it is easy to imagine how it would not hold true in the complex real world.

A better way to state the results is as follows. The Ricardian model shows that if we want to maximize total output in the world then,

first, fully employ all resources worldwide;

second, allocate those resources within countries to each country's comparative advantage industries;

and third, allow the countries to trade freely thereafter.

In this way we might raise the well being of all individuals despite differences in relative productivities. In this description, we do not predict that a result will carry over to the complex real world. Instead we carry the logic of comparative advantage to the real world and ask how things would have to look to achieve a certain result (maximum output and benefits). In the end we should not say that the model of comparative advantage tells us anything about what will happen when two countries begin to trade, instead we should say that the theory tells us some things that can happen.

I take a fairly simple but time tested stance on competitive advantage. It is a 3 legged stool, labor cost, quality, schedule=final customer price and profit. If any source of labor can provide all 3 attributes that is where the work should be done. If a labor source can only provide low labor costs but not quality or schedule(efficiency), then that source of labor is not viable. If a labor source is costly but high quality and highly efficient, in other words, on time the first time then that is usually where the work should be done.

Although the results follow logically from the assumptions, the assumptions are easily assailed as unrealistic.

Yeah, unrealistic is the polite way to put it. Some old division of labor stuff with a few fancy new words. The problem is that international relations must be competitive. Otherwise we'll get a regulated, planned, world economy where the One-Worlders sit in the middle controlling everyone else. Their advantage really doesn't compare. The rest will simply struggle to be "more efficient", longer working, less eating and most importantly less thinking serfs.

The usual way of stating the Ricardian model results is to say that countries will specialize in their comparative advantage good and trade them to the other country such that everyone in both countries benefit.

Big problem. Country by country specialization means dependence. Dependence means lost sovereignty. In todays high-tech world, flexibility is easy to achieve and there is no much need for specialization. But many governments are falling all over themselves to regulate and litigate the independent small producers out of existence. That's what the special interest wants, that's what they do. Silly economic theories are just the cover - bought and paid for.

Here's a good way to summarize the whole thing succinctly:

Bob is a brain surgeon. He can stuff envelopes, if you want him to, and can quickly work out a procedure to do this simple task very efficiently. More to the point, though, he can perform brain surgery.

Ted is a high school dropout. You could give him a copy of Neurosurgery for Dummies, and he could perform a lobotomy, eventually. He can also stuff envelopes, though he's not as quick as Bob at that, either.

There is some brain surgery to be done, and some envelope-stuffing to be done. Bob's better at both, so should we just have Bob spend half his time on each, and tell Ted to take a hike?

Of course not. Even though Ted isn't as good as Bob at envelope stuffing, Bob is so much better at brain surgery that it makes sense to put Ted to work stuffing envelopes and let Bob get on with practicing his trade. This is intuitively obvious.

Same thing in world trade. Sure, America can make tennis shoes. It might even be better at making tennis shoes than Malaysia. But Malaysia can make tennis shoes pretty well, and it's terrible at making bulldozers. So it makes the most sense for America to stick to making bulldozers, and Malaysia to stick to making shoes, rather than both countries trying to make both goods.

Comparative Advantage and Competition
William R. Hawkins
Thursday, March 04, 2004

Gregory Mankiw, Chairman of the Council of Economic Advisers, triggered a political firestorm when he told the Joint Economic Committee of Congress (JEC) on February 10 that outsourcing jobs is “just a new way of doing international trade.” Yet, he was correct in his assessment. It was his total lack of concern about the consequences that provoked even the Republican Speaker of the U.S. House, Dennis Hastert of Illinois, to respond, “I understand that Mr. Mankiw is a brilliant economic theorist, but his theory fails a basic test of real economics.”

It is this conflict between theory and reality that has always driven debates over international trade. This discussion has often been sliced between economists on the one hand, and historians and political scientists on the other. Economics is a social science, not a hard science, despite all the attempts to disguise this fact with graphs, equations, and computer models. Economics is filled with contrasting philosophical views of how the world should work.

Mankiw´s idealism is evident from other things he said during his JEC testimony. Consider the following: “International cooperation is essential to realizing the potential gains from trade. Trade agreements have reduced barriers to international commerce, and contributed to the gains from trade. A system through which countries can resolve disputes can play an important role in realizing these gains.”

This statement reflects the theory of comparative advantage in its most simplistic form. Countries are to specialize in particular fields and then trade with those who have specialized in complementary fields. The emphasis is on cooperation, not competition. Each trading state recognizes and accepts its place in the integrated global economy. Indeed, the increasing use of the terms “integration” and “global” in place of “competition” and “international” reflect the philosophical bent of 19th century classical liberalism for harmony over rivalry.

There is, however, very little in the history of international trade to support this concept. David Ricardo conceived his comparative advantage model at a time when even his native England was not yet a fully industrial nation. He thus drew heavily on pre-industrial concepts based on a “natural” division of labor and specialization based on climate, raw materials and local artisan skills. One of the more famous examples of this approach is Adam Smith=s observation about the difficulty of growing bananas in Scotland.

Today, it is possible to manufacture products almost anywhere because technology is not limited by soil or climate like agriculture; transportation costs have dropped; capital is fluid; and there are smart, skilled people everywhere. Related to this “unnatural” state is another critical fact that free trade theory does not take into account: In a large and complex world, multiple nations can have a comparative advantage in the same field. They thus become rivals in the attempt to gain as large a share of world markets as possible.

The United Nations Conference on Trade and Development (UNCTAD) puts out measurements of “revealed” comparative advantage based on an index that compares the share of a given sector in national exports to the share of the sector in world exports (known as the Balassa formula). According to this measurement, the United States, China, Germany and Japan all have a comparative advantage in miscellaneous manufacturing; the U.S., China, Japan and Singapore have comparative advantages in electronic components; the U.S., Germany and Japan have advantages in transportation equipment (mainly cars and trucks) and in non-electrical machinery; the United States and Germany have an edge in chemicals; China and Germany both have comparative advantages in basic manufacturing, while Japan has just lost it advantage. In information technology and consumer electronics, China, Japan, and Singapore are rivals, with the United States having lost ground but still close enough to recover its advantage with a little effort. Comparative advantage is a dynamic function, subject to change over time as rivals actively compete, trying to better their position and knock out the others.

Ambitious nations are never satisfied with their “assigned” place in the system. The American colonies revolted against a British Empire that did not want them to develop industry but simply maintain their comparative advantage in the production of raw materials. Ricardo=s own classic “wine and cloth” example was meant to show that Portugal should accept its role as a traditional supplier of wine and let England move ahead with the new industrial process of cloth production. This example was denounced as “free trade imperialism” by all nations which understood that developing new technology and manufacturing capacity was the path to both prosperity and power. The current impasse at the Doha Round trade talks reflects this historic rivalry between developed and developing nations.

China is not going to accept the U.S.-Japanese-German edge in automobile production and import vehicles. It will build its own auto industry, along with industries in aerospace, chemicals and steel. Beijing will use American transnational corporations to aid in its development efforts, since these firms do not care where they produce. China will also push forward with its shipbuilding industry, even though South Korea, Japan and the European Union are currently more advanced. What moves international commerce is the same motive that moves business in general: cutthroat competition and a relentless desire to expand into new fields. The key difference between domestic and international competition is that the latter also affects national capabilities, which in turn can shift the world balance of power and with consequences far greater than those experienced by domestic companies in their more circumscribed competition.

The term “trade war” is far more applicable to the world trading system than most people want to admit. Political science professor William R. Thompson, from a career spent looking at the international system, has reached this conclusion: “Unlike the pattern in warfare in which ascending states fight their way up through their regional neighborhoods before taking on the system=s most powerful state, commercial challenges are aimed immediately at the leading commercial power.” Today, that target is the United States.

In this global competition, the United States is losing. There is no field in which its domestic producers are without rivals, which means that if national leaders adopt the attitude that it doesn´t matter who wins, America will be defeated by those who do care about winning. A $549 billion trade deficit in goods, and increasing penetration of foreign firms into key sectors of the domestic American economy, indicate how rivals are running up the score.

Professor Mankiw does not apparently think in these terms. The critical question is whether the man who appointed Mankiw, President George W. Bush, understands the larger issues at stake. So far, there is no evidence that he does.

William R. Hawkins is Senior Fellow for National Security Studies at the U.S. Business and Industry Council.

I trust that the theory is mathematically correct -- in the aggregate. Today's problem becomes apparent when you take it down to the level of individuals.

Suppose, in the England/cloth/Portugal/wine example, that England "decides" to make only cloth and Portugal "decides" to make only wine. (I put the word in quotes because it isn't up to countries to make such decisions.) Then we have the potential of a lot of unemployed English winemakers and a lot of unemployed Portuguese clothmakers. Over time the employment market will adjust, with the people concerned finding other jobs or leaving the job market.

The speed of business and markets has been increasing for some time now, probably more than the speed of individual adjustment. This increases the likelihood that individuals will be left in the lurch as markets adjust. Furthermore, if markets adjust quickly enough, it's conceivable that a slow-moving individual could be caught out-of-step multiple times before he finds a niche or gives up.

Nobody is going to pay Bob's rate to stuff envelopes (or, Bob will not work at the pay that stuffing envelopes will pay).

It is a lot of words to explain something that is actually fairly simple. Outsoursing of High tech jobs has been made viable by those in the High Tech sector doing what they are paid for. Manufacturing outsourcing was also made viable by the High Tech sector doing what they were paid for by automating previously high skilled manufacturing tasks to the point of allowing a low skilled worker to accomplish.

Thinking About Protection: The Hawkins Prescription for Trouble

       Suppose the mercantilist model--that centuries-old paradigm of planned, coordinated, "balanced" protectionism now resurrected by William R. Hawkins to create a stronger America--were a viable policy alternative in August 1945, at the end of World War II. And let us take this supposition as an opportunity to assess the U.S. trade record, to see where it has been, economically and politically, and perhaps to see where it is heading. After all this, we may better see just what Hawkins has in mind.
        With the end of the Second World War, America, then by far the greatest military and economic power on earth, faced an extraordinary challenge: What kind of postwar world should America nurture? Broadly it had two options.
        First, should the United States retreat to its mercantilist, isolationist, divisive, protectionist, and inadvertently contentious stance of the twenties and thirties?
        Consider the history behind this question. Congress, which refused to ratify the Treaty of Versailles, rejected U.S. membership in the League of Nations. In 1922, Congress adopted the Fordney-McCumber Tariff, which led to a 44 percent average tariff on dutiable imports. That percentage was boosted to nearly 60 percent by the more widely imposed Smoot-Hawley Tariff of 1930, a record tariff that touched off retaliatory protectionism and divisiveness around the world. It also exacerbated the Great Depression (economist Jude Wanniski says Smoot-Hawley caused it) and contributed to the frictions that led to the Second World War.
        Under newly installed President Harry S. Truman, America in 1945 carried forward the flag of leadership earned by military victories in war-ravaged Europe and Asia. Therefore, should America seek a united, not a divided, globe, an international fraternity of nations predicated on, to borrow the slogan of IBM, "World Peace through World Trade," an international fraternity wherein nations are free to exchange goods and services, ideas and technology, capital and tourists, for the benefit of all concerned?
        Wisely, I think, America chose the second option, though it still clung to a number of mercantilistic ideas advocated in the accompanying article by William Hawkins. America fostered the United Nations, headquartered in New York, and the General Agreement on Tariffs and Trade (GATT), headquartered in Geneva.
        GATT, which celebrated its fortieth anniversary in 1987, seeks to promote free trade by requiring member nations signatory to any tariff ... (3100 of 19478 Characters)

Willie, you're a ARE the vast majority of the problem, and the primary reason why America's ability to compete has been stiffled.

Nobody is going to pay Bob's rate to stuff envelopes (or, Bob will not work at the pay that stuffing envelopes will pay).

The law of supply and demand applies to labor as well as goods and services. The only way to repeal it is with government intervention and we all know how well that works out.

Good analysis. It also shows (in the gardening example) why management is so important. However, the Marxist-Buchannanist-Merchantilists still haven't risen to the level of Adam Smith, much less Ricardo, and thus won't understand.
