International Trade Made Simple

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!

“Opulent in elegance. Bountiful in spirit”

It’s Friday morning here in Shanghai. My AP students are in the middle of their Macro Unit 2 test on Aggregate Demand and Aggregate Supply. I’m reading SAS’s weekly Parent Talk newsletter that I handed out to my homeroom this morning, and on the back cover is an advertisement for the housing compound across the street from school, “Rancho Santa Fe”.

I just had to post this to my blog, as I think it captures well the trajectory that rich, suburban, Shanghaites are heading as Shanghai and the other Eastern provinces continue to develop and get rich.

“Success has many stages.

Acquiring a definitive territory counts as the ultimate one.

Embracing the best nature and humanity have to offer.

Rancho Santa Fe Phase 3 is a magnum opus of a villa residence.

Opulent in elegance. Bountiful in spirit.

The grandeur lies not only in heritage, but the entirety of all that is perfect.”

I hope you enjoyed this as much as I did. Happy Friday!

China: formerly the world’s factory, now a nation of consumers…

Economics focus | From Mao to the mall | Economist.comChina - a nation of consumers

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.

Models for economic growth - IB Economics

As we study economic development in year 2 IB Economics, we examine different models for economic growth. Growth in GDP is not the only determinant of economic development, which in order to be measured effectively must account for human welfare determinants such as life expectancy, literacy rates, child mortality rates, distribution of income, and so on. However, it has been shown throughout history that economic growth, or the increase in real output and income, correlates directly with improvements in development factors like those above.

A macroeconomic mystery - the gap between America’s “rich” and “poor”

You Are What You Spend - New York Times

Fact:
The richest 20% of Americans earn 15 times the income of the bottom 20%.

Fact: The richest 20% of Americans only consumer 4 times as much as the poorest 20%.

Question:
Why don’t the richest 20% consume 15 times as much as the poorest 20%?
Consumption Gap
The author of this NYT opinion piece claims that the gap between America’s rich and poor is not as stark as the income figures suggest. While before tax income of the top 20% is around $150,000, the poorest 20% earn only around $10,000. Clearly these numbers indicate an enormous income gap in America.

However, when it comes to consumption, the poor consume an average of $18,000 on everything from food to housing to entertainment to transportation. The richest 20%, on the other hand, consume an average of only $70,000, less than half their before-tax income.

So the question is, is standard of living based on our income, or on our consumption? If it’s income, then there’s certainly a huge gap in standard of living between the rich and poor. But if we believe it’s consumption, then the gap is narrowed dramatically. The author claims the latter:

To understand why consumption is a better guideline of economic prosperity than income, it helps to consider how our lives have changed. Nearly all American families now have refrigerators, stoves, color TVs, telephones and radios. Air-conditioners, cars, VCRs or DVD players, microwave ovens, washing machines, clothes dryers and cellphones have reached more than 80 percent of households.

“Creative Capitalism”: Harnessing the power of markets to serve the poor - by Bill Gates

Bill Gates Issues Call For Kinder Capitalism - WSJ.com

“We could make market forces work better for the poor if we could develop a more creative capitalism…” - Bill Gates at the 2007 Harvard commencement address

Is capitalism capable of lifting the world’s 4 billion poor people out of poverty? Bill Gates, the world’s greatest beneficiary of capitalist markets, thinks the system that forms the foundation of our market economy requires some re-thinking. Gates is calling for “creative capitalism” in which firms respond to incentives aimed at developing technologies that serve the world’s poor.

Gates first expressed his interest in a capitalist system with a focus on helping the poor in his Harvard commencement address last year, and reiterated his vision last week at the World Economic Forum in Davos, Switzerland. Gates envisions a future where profits will motivate industies to create goods and services not just for the top 20% of the world’s income earners, those in the rich countries of the OECD (the “country club of the UN” as Hans Rosling calls it), but by developing products that are meant to benefit the world’s poorest people, those in the bottom 20%, who suffer most from poverty.

Watch the videos below and discuss the prospects of Gate’s vision becoming a reality.

Does economic growth = economic development? Not for China’s rural poor…

Grinding poverty defies China’s boom - International Herald Tribune

Here at SAS my year two IB Econ students have started off the new year with a new unit: Economic Development. So far in the semester we’ve learned about what makes economic development different than economic growth. While gross domestic product may offer an indication of a country’s level of economic activity and output, it says little about the reality of life for the common person of developing countries.

To offer a more rounded figure for determining the level of economic development, the United Nations Development Program has created an alternative to GDP, the Human Development Index. The HDI accounts for the GDP per capita, the average level of primary and secondary education attained, literacy rates, and the life expectancy of citizens, to offer a glimpse into the reality of not just material wealth, but health and education in developing countries.

Behold the Nano - “the people’s car”

The Nano comes with its own moral dilemma. - By Anne Applebaum - Slate Magazine

Tata Motors of India recently launched the world’s cheapest automobile, the Nano.

“…meet the Nano, possibly the most significant new car of the decade. Small, cute, and snub-nosed, it fits four people and a duffel bag, has a single windshield wiper, travels at 60 mph, and it’s all yours for the princely sum of $2,500…”

Tata plans to build and sell 250,000 Nanos this year in India, spreading production to Africa, South America, and Southeast Asia. Clearly the company is targeting not the traditional auto markets of Europe and North America, rather the regions traditionally thought of as poor and thus not associated with auto sales.photo

What is the meaning of this “car for the masses”? At first glance, it looks like the perfect solution for bringing millions of the world’s poor (if not super-poor) closer to the dream of achieving a quality of life previously only accessible by the world’s middle class and rich. Great,  so what could possible be bad about fulfilling the dreams of so many of the world’s poor? The answer? Externalities…

“Though the small Nano uses less gasoline than many larger cars, the enormous potential numbers could mean an equally enormous environmental impact. Since it will be a long time before Nano drivers will be able to afford the $20,000-plus hybrids now on the market, let alone a Honda FCX Clarity, the prototype experimental hydrogen car thought to be worth as much as $10 million apiece, that means an exponential rise in carbon emissions as well as other kinds of pollutants. The United Nations’ top climate scientist, Indian economist Rajendra Pachauri—chair of the Intergovernmental Panel on Climate Change, which shared the Nobel Peace Prize with Al Gore—has said he is already “having nightmares” about precisely this scenario.”

Herein lies the moral dilemma of the Nano: where does society’s desire to improve the lot of the world’s poor come into conflict with society’s desire to to improve the environment and minimize the impact global warming?

What do you think? Do the social benefits of a $2,500 car exceed the social costs it will likely impose? Does the Nano’s $2,500 price incorporate the full costs that its existence places on society and the environment? Should we jump for joy at the thought of millions upon millions of the world’s poor finally having access to the convenience of automobile transport? Or should we pause with uncertainty to contemplate the effect on the environment and the social costs that millions of cheap cars will impose on the world?

Exports, good - Imports, ALSO GOOD!

Foreign Policy: Why We Trade

Professor Russ Roberts, host of the EconTalk podcast, has an essay in the latest issues of Foreign Policy journal titled “Why We Trade”. In this piece, Roberts defends the benefits of trade from a broad perspective, beyond the popular political view of trade, usually along the lines of “exports, good - imports, bad”. Roberts compares this line of thinking (characteristic of presidential candidates of both the Republican and Democratic parties), to the 14th century, pre-Adam Smith view of world trade, known as mercantilism.

Mercantilism was a view of global economic interaction that placed emphasis on the accumulation of gold and other precious metals from abroad in exchange for your country’s exports. The doctrine failed to recognize the importance of imports from abroad, as this was viewed as a loss of wealth to foreigners. Mercantilists viewed wealth in terms of bullion or the amount of precious metals a country owned. Today, of course, our understanding of wealth has evolved to account for the amount of output, or products (goods and services), we are able to consume. Herein lies the flaw in the rhetoric of modern politicians who, “are always talking about the necessity of other countries’ opening their markets to American products. They never mention the virtues of opening U.S. markets to foreign products.”

IB - How much can governments do to fight poverty? Incentives, not politics, may be the key to effective development
