Is international trade really as good for a nation’s standard of living as economists say? And, what the heck is comparative advantage anyway? And what about the foreign currency market and those confusing supply & demand curves? Yes, the quest to understand the economic benefits of international trade is enough to make any citizen or first-year economic student vomit, tremble, get a headache, or at least curse.

Having been an AP Economics’ teacher for 8 years now, I must candidly admit that it took me a few years of study and research to try to reduce international trade to pure simplicity and understanding. Let me give it a shot below. I love simplicity.

The average “Joe Citizen” in almost any country in the world is suspicious of trade, and rightfully so, since he reads or observes factories being closed, jobs lost, and the feeling that somehow his country is going down the toilet as his own home fills up with foreign-made products. Unfortunately, what Joe Citizen does not understand is that the money his own nation is spending for those foreign products (imports) is spent right back into the pockets of his own country, increasing employment and income.

Let’s take a single, real-world, international trade example being careful to accurately explain the whole economic story:

Let’s say that the United States (we’ll say Wal-Mart) decides to buy several shirts costing $400 from a Chinese shirt manufacturer, in lieu of buying those same shirts from a shirt manufacturer in Elon, North Carolina (USA). As a US AP Economics’ teacher I am one of about only 47 Americans in Fairfax County Virginia, which not coincidentally ties to the number of AP Students I taught this year, that quickly understand that the decision to purchase the shirts from China, in lieu of the US manufacturer in North Carolina, is actually BETTER for America and will make my home country better off in the long run! What? Mr. Latter, are you Benedict Arnold, the American traitor, reincarnated?

Let me explain how the US benefits (and China too!) in simple terms ignoring foreign currency transactions, which will just confuse the discussion and cause the student to lose sight of what is really happening:

The first key point is that when Wal-Mart buys the shirts from China for $400 it can only pay China with US dollars. Why? Because Wal-Mart has only US dollars! It has no Chinese currency (Yuan). It literally drains its bank account of US dollars that are transferred/paid to China!

The second key point is that when China receives that same $400 US dollars for the shirts, China cannot, unfortunately, spend any of the $400 in its own economy since only the Yuan is accepted as a medium of exchange in China! China is now forced to either throw the currency away (not advised!), or immediately spend the money back to the USA (advised!).

In summary, China has actually traded a product (shirts!) for paper (US dollars!), and those US dollars cannot be spent in China. For China to receive any value at all for the shirts it sent to America, China must now spend the $400 back into the US economy for, say, a global positioning system (GPS) from FleetMatics out of Waverly, Massachusetts (USA). Cutting through to simplicity, in essence, it’s almost as if Wal-Mart (USA) just paid FleetMatics (USA) $400 directly for the shirts!

Yes, the “punch line” is that all home-currency spending by the domestic nation on foreign products (imports), in turn, are spent right back to the domestic nation increasing the domestic nation’s employment, income, and standard of living. (Note; this is shown in a nation’s balance of payments schedule which always nets to zero, but, yuk, who cares about that right now with summer coming!)

And, yes, let’s not forget that Elon, North Carolina shirt maker that did not get the original $400 from Wal-Mart in our above example! Our nation loves competition (ready for the Olympics?) and I am excited to see if that North Carolina shirt manufacturer can “raise their game” (increase productivity), and hopefully get the next shirt contract from Wal-Mart or some other firm! If not, well, that North Carolina firm may just have to close down.

If you are still reading this post at this point, you may be thinking the following if you have a little economics’ background: “But the US has a growing trade deficit with China, so China may not immediately buy that GPS system from FleetMatics for $400”. And, you are correct, but that is also not a problem for either the United States or China. What China is really doing right now is deciding to temporarily save or invest a minority percentage of their US dollars received back into America in lieu of buying US products. Said another way, China is not buying as many GPS’ as the US is buying shirts and, of course, we call that phenomenon the US trade deficit which immediately seems to speak “problem”. But it is really no problem at all! China is still spending their “saved” US dollars back into the US economy, but in different ways. China is saving and investing some of those US dollars directly into the United States economy by building plants in America, buying US stock to fund American companies’ expansions, and temporarily saving some of their dollars, for future US purchases, by buying US bonds to help the US government pay for the war in Iraq, the war against terrorism, and several other US government initiatives necessitating borrowing. Eventually, China will sell these US bonds and buy that GPS system or build more plants to employ more Americans!

Now one last thing. Promise! Let’s get back to why trade is really so economically advantageous to any nation that pursues it. And by advantageous, I mean how it increases our incomes and standards of living. In one word, the answer is “productivity”. If we go back to the original example of the US buying shirts from China and China taking the US dollars to buy the GPS, we remember that the shirt manufacturer from North Carolina was “left out in the cold” because Wal-Mart did not buy the shirts from them. We can logically conclude that perhaps some Chinese manufacturer of GPS systems was “left out in the cold” because some Chinese business elected to buy from FleetMatics in the USA, and not the Chinese GPS manufacturer. Wow, I love global competition! What a great way to incent businesses in both the USA and China to compete against each other and increase their productivity and conserve our nations’ scarce resources, increase our choice, and lower our costs!

Bloomberg.com: Economy - Korea Beef Deal Won’t Yield Trade Vote

Free trade: everyone either loves it or loves to hate it. South Korea and the US have been in negotiations for a landmark free trade agreement for years. Korea, however, has had a “beef” with US beef imports since 2003, when a case of Mad Cow Disease gave Korean officials the jitters and all imports were halted.

Even though Mad Cow has disappeared from American beef, the ban had remained, making it difficult for negotiators to come to any major agreements on the reduction of tariffs and other barriers to trade in other markets in which the US and Korea trade. Just last week, South Korea removed the beef ban, giving some analysts hope that a free trade deal may soon be agreed upon.

President Bush signed the agreement last year but has hesitated to pass it on to Congress; where certain Democratic politicians have refused to approve the agreement until S Korea removed the beef ban. Now that the ban has been lifted, however, it appears that the issues keeping an agreement from being reached may run deeper than the simple beef ban:

In addition, Ford Motor Co., unions and Democrats, including both Hillary Clinton and Barack Obama, all say the accord must be reworked to address what they call South Korea’s barriers to U.S. manufactured goods.

“I understand there are foreign policy considerations, but this is too important for us,” Stephen Biegun, vice president for government affairs at Ford said in an interview earlier this month. “We don’t see any sign that they are ready to change.”

Levin, who represents autoworkers in suburban Detroit, said the accord will need to be changed to address what he calls South Korea’s non-tariff barriers to U.S. manufactured goods, especially autos.

Clinton, in a response to questions from the Pennsylvania Fair Trade Coalition, said the agreement with South Korea “will cost America jobs.”

The S Korea / US Free Trade Agreement should bring a boost in trade between the two countries:

The U.S. is South Korea’s second-largest export market behind China, with shipments totaling $45.8 billion in 2007. Imports from the U.S. last year reached $37.2 billion. The trade agreement would eliminate or reduce tariffs on a wide range of goods including automobiles, vegetables and electronics.

Through free trade there are winners and losers. This is a theme we’ve explored in some depth already during our International Economics unit in AP Economics here at Shanghai American School. The winners, in the case of the S Korea/US FTA will likely be manufacturers in S Korea and service industries in the US. Judging by Ford Motor Company’s response to the FTA, we can assume that American manufacturers will be losers from the accord.

Does this make it bad, however? According to macroeconomic theory, no. The removal of tariffs on imports from S Korea will force American manufacturers to become more competitive and achieve greater efficiency, both which will result in a more efficient allocation of resources in both S Korea and the US. If Ford, for example, sells fewer cars because of in influx of high quality, affordable Korean automobiles, then Ford may be forced to shut down some of its plants in the US. This will lead to the loss of American jobs, just as Hillary Clinton claims it will.

But in the long-run, America as a whole should be better off for it. Manufacturers in the US will focus more on capital intensive goods such as industrial equipment, the manufacture of which requires highly skilled labor, which America has in abundance. In addition to industrial equipment and other high skilled manufactured goods, the US service sector should benefit from freer trade with S Korea.

With beef being resolved, the U.S. banks, insurance companies and other services companies that stand to gain the most from this accord are gearing up their lobbying efforts.

Beef “has been our biggest obstacle in having a meaningful dialogue on the benefits of this agreement,” said Matt Niemeyer, vice president for the business insurer ACE Ltd. and a former U.S. trade official. “It’s now time to work with Congress to find a way to move this important agreement this year.”

Another theme of our final AP Econ unit, I could say, is that politics and economics don’t always mix well. The opposition to the S Korea/US FTA among Congressional Democrats is more political than it is economic. Jobs will be lost, that’s true, but overall trade between two technologically advanced, developed countries like the US and S Korea should do more for improvements in efficiency and in resource allocation than it will in harm for a handful of American workers who may find themselves out of work due to greater demand for imported automobiles.

*A tariff on Korean automobiles results in the following outcomes:

• The quantity demanded of automobiles is less than it would be without a tariff (Q4 rather than Q3)
• The quantity supplied by American auto manufacturers is greater than it would be without the tariff (Q2 rather than Q1)
• The difference between Q2 and Q1 represents an overallocation of resources in America towards automobile manufacturing.
• The domestic quantity demanded exceeds the domestic quantity supplied. The difference (Q4 - Q2) is made up for by imports from S Korea.
  
• The government earns revenue equal to the area of the yellow rectangle (amount of tariff x number of cars imported)
• Society experiences a loss of efficiency (deadweight loss) equal to the combined areas of the green triangles Y and X. This is consumer surplus lost, accounted for by the higher price paid by American consumers imposed by the tariff.

In the model above, the removal of a tariff on Korean automobiles will result in a decrease in output by American firms from Q2 to Q1, an increase in imports from Q4 - Q2 to Q3 - Q1, and an increase in consumer surplus, efficiency, and better overall allocation of resources in America.

Discussion questions:

1. How does the graph illustrate the concept of “winners and losers from free trade”?
2. Who gains and who loses from free trade with the US within Korea?
3. Is it possible that a free trade agreement with Korea would actually create jobs in America? Explain…
4. Why do politicians oppose free trade deals that would result in such improvements in efficiency, allocation of resources, and even in the employment opportunities for American workers?

The $1.4 Trillion Question - James Fallows - the Atlantic

What’s the deal with American consumers? How, exactly, does a nation’s average savings rate fall to 2%, then 1%, and then become negative, like in the US over the last couple of years? What does negative savings actually mean? It means that Americans consumer more than they actually produce.

On the micro level, the only way to consume beyond ones income is to borrow from someone else to pay for the additional consumption. In other words, savings must be negative for one to consume beyond his or her income. The US is a nation of borrowers, but from whom do we borrow? China, in short.

China is a nation of “savers”, where national savings averages 50% of income. What exactly does this mean? Well, just the opposite what negative savings means; rather than consuming more than it produces, the Chinese consume only about half of what it produces. Here’s how James Fallows, a Shanghai-based journalist, explains the China/US dilemma:

Any economist will say that Americans have been living better than they should—which is by definition the case when a nation’s total consumption is greater than its total production, as America’s now is. Economists will also point out that, despite the glitter of China’s big cities and the rise of its billionaire class, China’s people have been living far worse than they could. That’s what it means when a nation consumes only half of what it produces, as China does.

What happens to the rest of China’s output? Naturally, it’s shipped overseas for Americans and others in the West to consume. The irony is that the consumption of China’s products has been kept affordable and cheap thanks to the actions the Chinese government has taken to suppress the value of the RMB, thus keeping its products cheap and attractive to American consumers.

When the dollar is strong, the following (good) things happen: the price of food, fuel, imports, manufactured goods, and just about everything else (vacations in Europe!) goes down. The value of the stock market, real estate, and just about all other American assets goes up. Interest rates go down—for mortgage loans, credit-card debt, and commercial borrowing. Tax rates can be lower, since foreign lenders hold down the cost of financing the national debt. The only problem is that American-made goods become more expensive for foreigners, so the country’s exports are hurt.

When the dollar is weak, the following (bad) things happen: the price of food, fuel, imports, and so on (no more vacations in Europe) goes up. The value of the stock market, real estate, and just about all other American assets goes down. Interest rates are higher. Tax rates can be higher, to cover the increased cost of financing the national debt. The only benefit is that American-made goods become cheaper for foreigners, which helps create new jobs and can raise the value of export-oriented American firms (winemakers in California, producers of medical devices in New England).

Clearly, a strong dollar is good for America in many ways. The dollar’s strength in the last decade can be credited partially to the Chinese, who have been buying dollar denominated assets in record numbers over the last seven years.

By 1996, China amassed its first $100 billion in foreign assets, mainly held in U.S. dollars. (China considers these holdings a state secret, so all numbers come from analyses by outside experts.) By 2001, that sum doubled to about $200 billion… Since then, it has increased more than sixfold, by well over a trillion dollars, and China’s foreign reserves are now the largest in the world.

China’s purchase of American assets keeps demand for dollars on foreign exchange markets strong, thus the value of the dollar high relative to other currencies, allowing American firms and consumers the benefits of a strong dollars described above.

As we learn in AP Economics, a nation’s balance of payments consists of the current account, which measures the difference between a country’s expenditures on imports and its income from exports (China last year had a $232 billion current account surplus with the US, meaning the US bought more Chinese goods than China bought of American goods), and the capital account, which measures the difference between the inflows of foreign money for the purchase of real and financial assets at home and the outflows of currency for the purchase of foreign assets abroad. In the capital account, China maintains a deficit (meaning China holds more American financial and real assets than America does of China’s), to off-set its current account surplus.

The two accounts together, by definition, balance out… usually. Any deficit in the China’s capital account that does not cover the surplus in its current account can be held as foreign exchange reserves by the People’s Bank of China. The PBOC, however, prefers not to hold excess dollars in reserve, as the dollar’s value is continually eroded by inflation and depreciation; therefore it invests the hundreds of billions of excess dollars it receives from Americans’ purchase of Chinese goods back into the American economy, buying up American assets, with the aim of earning interest on these assets that exceed the depreciation and inflation rates.

The “assets” the Chinese are using their large influx of dollars to buy are primarily US government bonds. The government issues these bonds to finance its budget deficits (when government spending is greater than tax revenue; this figure was projected at around $400 billion this year alone!), and the Chinese are happy to buy these bonds for a couple of reasons: They are secure investments, meaning that unless the US government collapses, the interest on US bonds is guaranteed income for China. That’s one reason; but the primary reason is that the purchase of these bonds puts US dollars that were originally spent by American consumers on Chinese imports right back into the hands of American consumers (via government spending or tax rebates), so they can continue buying more Chinese imports.

The Chinese demand for dollar denominated financial assets, including government bonds, corporate stocks and bonds, and real assets like real estate, factories, buildings and so on, has resulted in a long period of a strong dollar. If the Chinese ever decided to stem the flow of dollars into American assets, the dollar’s value would plummet to record lows, leading to high inflation and eventually a balancing of America’s enormous current account deficit with China and the rest of the world.

However, a falling dollar is the last thing China wants to see happen, for two reasons: One, it would make Chinese imports more expensive thus less attractive to American households, thus harming Chinese manufacturers and slowing growth in China. Two, US dollars are an asset to China. Its $1.4 billion of US debt would evaporate if the dollar took a major plunge. To China, this would represent a loss of national wealth; in effect all that “savings” that makes China so unique would disappear as the dollar dived relative to the RMB. For these reasons, it seems likely that China will continue to be a willing buyer of America’s debt, thus the financier of Americans’ insanely high consumptive lifestyle.

When it comes to America’s low personal savings rates, I have a theory here as to why we can’t break the consumptive habit that’s caused us to run up $9.3 trillion of national debt. It relates to something I teach my Asian History students when we study ancient China.

Confucius said something about government that might just explain why Americans have evolved into the negative savers that we are: “If a government desires what is good, the people will be good. The character of a ruler is like wind and that of the people like grass. In whatever direction the wind blows, the grass always bends.”

China, long acknowledged as the world’s factory, could suffer if falling demand for its exports in the US results in a decline in aggregate demand and GDP here as some economists believe it will. But not all economists agree on the importance of exports to China’s domestic economy:

The increase in net exports (exports minus imports) has never been the main source of China’s growth. It contributed two to three percentage points to annual GDP growth between 2005 and 2007, whereas domestic demand (consumption and investment) added eight to nine percentage points.

But the latest figures show that exports have become even less important as a driver of growth. The World Bank’s latest China Quarterly Update suggests that net exports contributed only 0.4 percentage points to GDP growth in the year to the fourth quarter of 2007 (see left-hand chart). Overall GDP growth slowed only modestly (to 11.2%) because of faster growth in domestic demand, which contributed an impressive 10.8 percentage points.

In IB Economics we’ve been studying concepts relating to balance of trade and exchange rates. The Marshall-Lerner Condition and the J-curve are two concepts that explain the relationship between a the exchange rate for a nation’s currency and the country’s balance of trade. (click on the graph to see a larger version)

Common sense might indicate that if a country’s currency (let’s say the US dollar) depreciates relative to other currencies, then this should lead to an improvement in the country’s balance of trade (economists call this the current account). The reasoning goes as such: a weaker dollar means foreigners will have to give up less of their money in order to get one dollar’s worth of American output. At the same time, since the dollar is worth less in foreign currency, imports become more expensive, as Americans have to fork over more dollars for a certain amount of another country’s output; hence, imports should decrease.

Fewer imports and more exports means an improvement in the country’s balance of trade, right? Well, not necessarily. What matters is not whether a country is importing less and exporting more, rather, whether the increase in income from exports exceeds the decrease in expenditures on imports. Here is where the Marshall-Lerner Condition can be applied. Continue Reading »
