Planet Money Podcast – “China’s Giant Pool of Money”

NPR’s Planet Money team did a great podcast last week about China’s accumulation of US dollars from its large trade surplus with the United States. This story offers a great illustration of the theories I introduced in my recent video lesson, The Relationship between the Current Account Balance and Exchange Rates

Listen to the podcast, watch the video lesson, and respond to the discussion questions that follow.



-

Discussion Questions:

  1. Why does the Chinese Central Bank possess over $3 trillion of foreign exchange reserves?
  2. What does the Chinese Central Bank do with the vast majority of the money it earns from the sale of its exports that it does NOT spend on US goods? Why not keep this money in cash?
  3. Why does the Chinese Central Bank manage the value of its currency, the RMB? Why not let the exchange rate be determined by the free market?
  4. As the RMB is slowly strengthened against the dollar, who are the winners and losers? What impact should a stronger RMB have on the balance of trade between China and the US?

A closer look at Apple’s iPad and iPhone – “made in America”?

I have two  interesting stories on Apple and the iPad to reflect on today.

First, ABC’s Nightline recently became the first Western journalists actually welcomed into an Apple assembly plant in China. The show recently aired a 15 minute feature on working conditions inside Apple’s Foxconn factory in Shenzhen, China last week. Watch the video and then scroll down for what may be some additional surprising news about Apple’s operations in China.

Next, the story that has gone unreported lately is a University of California study titled “Capturing Value in Global Networks: Apple’s iPad and iPhone”. The study’s most interesting finding, in my opinion, is the tiny percentage of the total value of Apple’s iPhone and iPad that actually goes to the Chinese manufacturers of the products. The charts below, from the study, show how the value is divided among the various groups involved it their production and sales:

The Economist provides the analysis:

The chart shows a geographical breakdown of the retail price of an iPad. The main rewards go to American shareholders and workers. Apple’s profit amounts to about 30% of the sales price. Product design, software development and marketing are based in America. Add in the profits and wages of American suppliers, and distribution and retail costs, and America retains about half the total value of an iPad sold there. The next biggest gainers are South Korean firms like Samsung and LG, which provide the display and memory chips, whose profits account for 7% of an iPad’s value. The main financial benefit to China is wages paid to workers for assembling the product and for manufacturing some inputs—equivalent to only 2% of the retail price.

A student today asked why Apple doesn’t produce its products in the United States, where an economic downturn has left 14 million American out of work for the last three or four years. If iPads and iPhones were just made in America, jobs could be created, households would have more income to spend on Apples products, and both the country and the economy would benefit.

The data in the UC study indicates that in fact, more than half the value of an iPad or iPhone does end up in the hands of Americans. But Apple could never achieve the low costs and high profits that it does by assembling its products in the US. After watching the Nightline video above, it should be clear that the type of production involved in Apple factories’ is very low-skilled and labor-intensive. Using American labor, with its unions, minimum wages and 40 hour work weeks, would require Apple to employ such large numbers of workers and raise the company’s variable cost to such a level that the firm’s profits would be reduced significantly and its sales would fall dramatically. Apple would lose out to foreign producers of smart phones and tablet computers, such as LG, Samsung, Sony and others, which would continue assembling their goods with Chinese labor.

Ultimately, any gain to the low-skilled American workers (presuming Apple could even find enough to do the work of the 400,000 Chinese employed in the production of Apple products in China), would be offset by a loss of profits enjoyed by the millions of Americans who hold shares in Apple Computer and the thousands of American who are employed engineering and designing its products, as the firm’s sales would slip in the face of lower-cost competitors.

So this student’s question identifies an interesting paradox: America, with its large pool of unemployed workers, will never be attractive as a place to produce labor-intensive products such as phones and tablet computers, due to the vast wage differential between the US and China. And even if one firm did decide to produce its products in America, the gains to low-skilled workers who may find minimum wage work in the new assembly plants would be off-set by losses to the firms’ shareholders and the high-skilled workers whose jobs would be lost as sales decline due to the lower prices offered by lower-cost competitors.

The lesson here is two-fold: First, Apple and other American technology companies should continue using Chinese labor to assemble their products, and second, America is better off for it: lower costs mean cheaper products and higher sales, thus greater employment in the high-skilled sectors of the US economy, and more profits and returns on the investments of shareholders in American corporations. Americans are richer and enjoy a higher standard of living thanks to the millions of Chinese working in factories assembling the goods we consume.

Keep in mind, this analysis did not even consider the effect on the Chinese economy and the millions of Chinese workers (whose lives are much harder than the typical American) should companies like Apple shut down their Chinese manufacturing plants. That’s a whole other blog post!

Why the falling rupee makes Mr. Welker a happy man! (and may help the Indian economy in the long-run)

Indian Rupee hits all-time low against the dollar – CBS News

A couple of years ago I wrote what I would call a “fantasy” blog post about how the recent depreciation of the British pound would have made a ski trip to India a whole lot cheaper since the tour company I was planning to go with quoted its prices in the British currency. Well, at the time I wasn’t really planning to go skiing in the Himalayas, but this year, because of a fall in the value of another currency, I really AM going to ski in the Himalayas!

The chart below shows how the value of the Swiss franc has changed against the Indian rupee over the last year and a half.

The Value of the Swiss Franc in terms of India Rupees – last 18 months


As can be seen, the franc, which is the currency in which I get paid here in Switzerland, has risen from only 40 rupees 18 months ago to as high as 63 rupees in August this year, and is currently at 57 rupees per Swiss franc. We’ll explore the underlying causes of this appreciation of the franc in a moment, but first let’s examine its effect on my dream of skiing in the Himalayas.

So just yesterday morning I did, at last, after six years of dreaming of this adventure, book a six day guided ski trip in the Indian Kashmir town of Gulmarg, which sits at an elevation of 2800 meters and has lift-accessed skiing up to 4,000 meters, making Gulmarg the second highest ski resort in the world. Okay, enough facts. The strong franc made this trip a reality for me for the following reason:

  • 18 months ago, the 40,000 rupee price tag of this ski trip would have meant a cost of 1,000 swiss francs.
  • Today, due to the strong franc, the 40,000 rupee price tag means this trip is only costing me 700 swiss francs.
Due to the strengthening of the franc, and the weakening of the rupee, my Himalayan ski odyssey is now costing me 30% less than it would have 18 months ago… so… I’m doing it! YEAH!
-
The Swiss currency has appreciated by 42.5% in the last 18 months against the India rupee. WHY?! What could be going on in the world that accounts for this massive swing in exchange rates? There are a few causes worth mentioning here, which have to do with factors within Switzerland and India, but also external factors beyond the control of either country. Here are some of the major ones:
-
In Europe:
  • The franc has risen against most world currencies, not just the rupee, due, ironically, to economic uncertainty in the rest of Europe. Since Switzerland has its own currency, and a strong economy, whereas all of its European neighbors have a common currency (the euro), and struggling economies, investments in Swiss assets (primarily savings accounts and government debt) have become increasingly attractive. This has caused demand for francs to rise, causing its value to increase against most currencies.
  • The debt crisis in the rest of Europe, most notably in Greece and Italy, reduces certainty among investors in these European governments’ ability to repay their debt, creating further demand for investment in Switzerland, causing the franc to rise.
In India:
  • According to the Associated Press, “Slowing growth, a swelling current account deficit and waning investor interest in India are adding to pressure on the rupee…” India runs a large trade deficit, equaling about 3% of the nation’s GDP. This means Indians are dependent on imported goods, while foreigners do not demand as many of its exports. This puts downward pressure on the exchange rate of the rupee.
  • In addition, the “slowing growth” rate in India sends the signal that the country’s central bank may lower interest rates to try and stimulate GDP. However, the expectations of lower interest rates in the future make international investors look elsewhere for investments with relatively higher returns.
  • Next, weaker growth prospects make investments in Indian assets (such as corporate stocks or bonds) less attractive to international investors, since they expect demand for Indian output to slow in the future, thus demand for rupees declines now.
  • Finally, the decline in the rupee’s value itself is fueling a further increase in the value of the franc. Not all currency exchanges are for the purpose of purchasing a nation’s goods or its assets. Much currency trading is among forex brokers who buy and sell currencies to hold as assets themselves. The weakening of the rupee may be fueling speculation about the future value of the rupee, which acts as a self-fulfilling prophecy, as forex investors will continue to swap rupees for other currencies, including the Swiss franc.
All this adds up to one thing for me: A 30% discount on my ski vacation to India! Of course, for the Indian economy, a weaker rupee might be just what is needed to boost future economic growth. As the rupee falls and the Swiss franc and the US dollar gain value, not only will ski vacations to India become more attractive to foreigners, but so will other exports from the South Asian nation. That 3% trade deficit that has contributed to the rupee’s decline may begin to move towards the positive if foreigners like me begin taking more trips to and buying more goods from Indian firms.
-
The weaker rupee could, in the long-run, increase total demand for India’s output, which would improve employment and growth prospects on the sub-continent. Furthermore, if India’s growth rate picks up due to increased net exports, the Indian central bank may be able to raise interest rates a bit, reducing the incentive for investors to flee the rupee and put their money in countries with higher returns.
-
Through this process of self-balancing, in time the weaker rupee will probably lead to an improvement in India’s economic situation and eventually the rupee will begin to strengthen against the currencies of India’s trading partners. But for now, I’m going to enjoy my week of guided skiing in the Himalayas, and thank the forex traders and currency speculators for allowing me to take this dream vacation for such a bargain price!

Excuse me, China… could you lend us another billion? Understanding the imbalance of trade between China and the United States

The $1.4 Trillion Question – James Fallows – the Atlantic

American consumers are a curious bunch. Up until 2007, the average savings rate in the United States fell as low as 1%, and during brief period was actually negative. What does negative savings actually mean? It means that Americans consume 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, for one…

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.
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 (In 2008 China 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 financial 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 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, 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.

Discussion Questions:
  1. Many people in America are terrified that the Chinese might dump their dollar holdings. What would happen to the value of the US dollar if China decided to change its foreign reserves to another currency?
  2. Why is it very unlikely that China will do this? In other words, how does the status quo benefit China as well as the US?
  3. How do American households benefit from China’s financing of the government’s budget deficits? In what way to they suffer from this arrangement?
  4. Do you think America can continue to finance its budget deficits through the continued sale of debt to foreigners forever? Why or why not?

Trade balances around the world

The table below shows the trade balances for the nations from which my year two IB Economics student come. They are ranked in order from the country whose trade deficit makes up the largest percentage of its GDP (Zimbabwe) to the country whose trade surplus makes up the largest percentage of its GDP (Germany). The blue bars represent the value of the deficit or surplus of each nation. As can be seen, Zimbabwe’s trade deficit is very small in dollar terms, but since its economy is also very small this deficit makes up a large percentage of its total GDP. Click on the image to visit an interactive version of the chart on which you can study the data more closely. Then answer the questions that follow.

Discussion Questions:

  1. Identify and define the four components of an nation’s current account balance.
  2. According to the data, which three countries are the most import dependent? Which three countries are the most export dependent? Which country has the most balance trade in goods and services? Which has the most imbalanced trade?
  3. If your country is one of deficit countries above, answer the following two questions:
    1. Assuming its currencies’ exchange rates is floating, explain how persistent current account deficits will affect a country’s exchange rate over time?
    2. Summarize and explain the likely effects of a current account deficit on the following: a) the financial account balance, b) domestic interest rates, and c) national debt.
  4. If your country is one of the surplus countries above, answer the following two questions:
    1. Assuming its currencies’ exchange rates is floating, explain how persistent current account surpluses will affect a country’s exchange rate over time?
    2. Summarize and explain the likely effects of a current account surplus on the following: a) domestic savings rates, b) the financial account balance.
  5. What are the various methods a country can take to reduce a current account deficit? What is the benefit of having a balanced current account as opposed to a large deficit or surplus?

Deteriorating terms of trade and the current account balance

U.S. Trade Gap Widens on Oil Imports – WSJ.com

Terms of trade is a term that is often misunderstood by IB Economics students. Simply put, a nation’s terms of trade refers to the relative price of a country’s exports to its imports.

When a country’s imports increase in price, while the value of its exports stays the same, the country’s terms of trade are said to deteriorate. As a nation experiences deteriorating terms of trade, it finds itself moving towards a deficit in its current account, meaning that expenditures on imports are growing more than income from exports, also called a trade deficit.

The United States has run trade deficits for most years since 1970. Since 2004 the US has annually spent over $600 billion MORE on imports than it earned from the sale of its exports. (Balance of trade data going back to 1960 can be found here).

Usually, when a country enters a recession, it would be expected that its balance of trade would improve, since households demand fewer imports and domestic inflation decreases making the country’s products more attractive to foreign households. In fact, in 2008, when the US entered its current recession, its trade deficit actually decreased. Recently, however, due to the weakness of many of its trading partners and a deterioration in terms of trade, America’s recession is accompanied by a deepening trade deficit:

The U.S. trade deficit widened for the first time in eight months during March, as the price and use of imported oil both climbed.

The U.S. deficit in international trade of goods and services increased to $27.58 billion from February’s revised $26.13 billion, the Commerce Department said Tuesday. Originally, the February deficit was estimated at $25.97 billion.

U.S. exports in March slipped by 2.4% to $123.62 billion from $126.63 billion as trading partners bought less consumer goods and cars from the U.S. U.S. imports fell at a lower rate, dropping 1.0% to $151.20 billion from February’s $152.76 billion

Discussion Questions:

  1. How did rising oil prices lead to an increase in America’s trade deficit?
  2. What determines demand for American exports in the rest of the world? Why is demand for American goods and services falling even as their prices decline due to deflation in the US?
  3. Where does America get the money to buy hundreds of dollars more in imports than it sells in exports? What do foreigners do with all the US dollars they earn from their enormous trade surplus with the US?
  4. Why doesn’t the US government simply place tariffs or quotas on imports to try and achieve more balanced trade with the rest of the world? Is this an appropriate response to a trade deficit?

“Buy American” is Un-American (The U.S. Stimulus Package)

One of the greatest “ah-ha” moments in all of economics is when an economics’ student or citizen learns for the first time that every time a domestic buyer purchases a foreign product or import that those same U.S. dollars spent on the foreign product go to a U.S.-based company, not a foreign company. Yes, I am telling you that when you (or Wal-Mart) buy Chinese shirts, your same U.S. dollars spent quickly end up in the hands of, say, Apple, Microsoft, Garmin, or General Electric to increase U.S. employment, profits, and U.S. stock prices!

I decided to write this particular blog because of the fact that the recently passed $800 Billion U.S. stimulus bill has some “buy American” provisions within it. Based on an intuitive hunch, I believe that over 99% of adult Americans believe that these “protectionist” clauses somehow help our economy. Yes, the vast majority of U.S. adults believe that it is clearly more advantageous to “buy American” in order to keep the money or wealth within America in order to increase U.S. employment, profits, and U.S. stock prices. In true economic fact, however, if U.S. citizens “buy American” solely out of patriotism (and not because they think it is a superior product) they actually HURT America because the U.S. dollars spent out of patriotism on that American company are, therefore, unintentionally withheld from another more efficient and deserving American country via the “trade loop”.

Let me try to explain this “trade loop” in more detail so that I may actually be able to convince you of this amazing “180 degree” revelation: “Buy American” is Un-American

Let’s say that the United States (we’ll say Wal-Mart) decides to buy many shirts costing $400 from a Chinese shirt manufacturer, in lieu of buying those same shirts from, say, a shirt manufacturer in Elon, North Carolina (USA). 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 U.S. currency away (not advised!), or immediately spend the money back to the USA (advised!).

In summary, China has initially 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!

Yes, the economic “punch line” is that all spending by the domestic nation on foreign products (imports), in turn, are spent immediately back to the domestic nation increasing the domestic nation’s employment, income, and standard of living. (Note; this is also shown and reported in a nation’s balance of payments schedule if you are skeptical about what you are reading!)

And, yes, let’s not forget about that Elon, North Carolina shirt maker that did not get the original $400 from Wal-Mart in our above example! Any good economy promotes competition and I am excited to see if that North Carolina shirt manufacturer can “raise their game” (increase productivity and/or quality), and hopefully get the next shirt contract from Wal-Mart! If not, well, that North Carolina firm may just have to close down. But remember, the key point, the $400 spent for the shirts went to Fleetmatics in Waverly, Massachusetts, in lieu of the Elon, North Carolina shirt manufacturer. If you would have “bought American” even though the Chinese shirts were preferable, you would have prevented the more effective U.S. business in Waverly from getting your U.S. dollars by giving them to the less efficient Elon manufacturer. In short, you would have contributed to American inefficiency and slowing productivity, hurting our country! And that is un-American!

Now, 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 form U.S. import purchases. 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 not as big a problem as most people think! 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 other US government initiatives necessitating borrowing. Eventually, China will sell these US bonds and be forced to use those U.S. dollars to buy that GPS system or build more plants to employ more Americans!

In summary, when citizens of any country in the world buy the product that is best for them based on a combination of quality and price, they will be taking the most patriotic action possible to help their own country they love so much! If a domestic citizen sees the foreign product as a better alternative to the domestic product, buy it! Your money spent will immediately find its way back through the “trade loop” to another business within your country!

Of course, this is why all economists from around the world know that international trade, and not protectionism, helps a country’s standard of living and promotes efficiency and rising standard of livings!

The Marshall-Lerner Condition, the J-curve, and the US trade deficit

For a video lesson on the Marshall Lerner Condition and the J-curve, click here: The Marshall-Lerner Condition (HL Only) | The Economics Classroom

Read the following article before reading the blog post below:
Managing Globalization » Business Blog » International Herald Tribune » Blog Archive » Here’s that silver lining, finally

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.

The M-L condition examines the price elasticities of demand for exports and imports of a particular country. Say the US experiences a depreciation of its currency (as it has over the last year or so). If foreigners’ demand for exports from America is relatively elastic, then a slightly weaker dollar should cause a dramatic increase in foreign demand for American output, causing export income in the US to rise dramatically. On the other hand, if American’s demand for imports is highly price elastic, then a slightly weaker dollar should likewise cause Americans’ demand for imports to decrease drastically, reducing greatly American’s expenditures on imports. If the combined elasticities of demand for exports and imports is elastic (i.e. the coefficient is greater than 1), then a depreciation of a nations currency will shift its current account towards surplus. This is the Marshall-Lerner Condition.

Marshall-Lerner Condition: If PEDx + PEDm > 1, then a depreciation or a devaluation of a nation’s currency will shift the the balance on its current account towards surplus.

So what if the Marshall Lerner Condition is not met? Demand for exports and imports may not always be so responsive to changes in exchange rates. Imagine a scenario where a weaker dollar does little to change foreign demand for America’s output. In this case income from exports may actually decline (in real terms, since the dollar is weaker) as the dollar depreciates. Likewise, if Americans’ demand for imports is highly inelastic, then more expensive imports will only minimally affect Americans’ demand for imported goods, in which case expenditures on imports may actually rise as they become more expensive. In this case, where the elasticities of demand for exports and imports are highly inelastic, a depreciation of the currency will actually worsen a trade deficit. Americans’ import expenditures will go up while export income from abroad will decline shifting the current account further into deficit.

In the article above, some data is presented that points to evidence that in the US today, the Marshall-Lerner Condition is in fact being met:

“Exports in the year through September are up by 12 percent from 2006, while the dollar’s trade-weighted exchange rate dropped by only 6 percent. That means foreigners may actually be spending more – even in their own currencies – on American products. It’s a support that the American economy, and in turn the global economy, can really use right now.

Of course, this process isn’t helping the trade deficit too much, No one, it seems, can change Americans’ taste for foreign products. But it does show, for all to see, that the risks of an open economy are at least somewhat balanced by the benefits.”

An increase in exports of 12% in response to a 6% weakening of the dollar indicates a price elasticity of demand coefficient for America’s exports of 2, meaning foreigners are highly responsive to cheaper US goods.

We can assume that Americans’ demand for imports is highly inelastic, as the article hints at when it says, “imports to the United States, including oil, are still rising in volume and value.” If a 6% weaker dollar leads to an increase in expenditures on imports, then demand must be less than one. In order for M-L Condition to be met, PEDx+PEDm must be greater than 1. Clearly, with a PEDx of 2, the condition is met, and a weaker dollar in leading to an improvement in America’s balance of trade with the rest of the world.

Discussion Questions:

    1. What is the J-curve effect? Based on the evidence from the article, where on the J-curve is the US right now?
    2. Is America experiencing an improvement in or a worsening of its current account deficit?
    3. What determinants of demand are fueling America’s ever-increasing expenditures on imports?
    4. What should happen to the elasticity of demand for imports if the dollar remains weak in the long-run? How will this affect America’s position on the J-curve?

Big trouble in little China – how slowing growth may mean major problems for the Chinese Communist Party

How high is China’s jobless rate? | The great wall of unemployed | The Economist

China Faces Unemployment Woes

Unemployment in China is a big deal. The legitimacy of the Chinese Communist Party hinges on its ability to assure  stable jobs and income growth for the 300 million “middle class” Chinese who live in the country’s cities. When the urbanites are unhappy, trouble ensues.

So a dip in economic growth rate into single digits, while we in the West may think of it as silly to fret about, is a major deal for China. Interestingly, according to the Economist newspaper, unemployment data in China is notoriously unreliable; in fact analysts have no clear idea of just how much unemployment there is:

Until the 1990s, the government more or less guaranteed full employment by providing every worker with an “iron rice bowl”—a job for life. But when soaring losses at state-owned firms forced the government to lay off about one-third of all state employees between 1996 and 2002, the official unemployment rate rose only slightly. Today it is 4% in urban areas, up from 3% in the mid-1990s.

But the official rate excludes workers laid off by state-owned firms. Thus at the start of this decade, when lay-offs peaked, it hugely understated true unemployment. Over time, as laid-off workers have found jobs or left the labour force, the distortion will have shrunk. Another flaw is that the official unemployment statistics cover only people who are registered as urban dwellers. An estimated 130m migrant workers have moved from the country to the cities, but there is no formal record that they live there, so they are ignored by the statisticians. After adjusting the official figures for these two factors, several studies earlier this decade concluded that the true unemployment rate was above 10%—and might be even as high as 20%.

The textbook definition of unemployment is the percentage of the labor force actively seeking but unable to find a job. In China, however, the “labor force” only includes the 25% of the country’s population that lives in cities, and the massive number of workers who were fired from state-owned enterprises over the last decade are mysteriously excluded from official figures. 4% unemployment, the official number, puts most developed countries to shame, as it represents extremely low levels of unemployment.

Despite the fuzziness in the figures, one thing is for sure, slower economic growth, even though it is still expected to be between 8-9% this year, means fewer new jobs in China, hence the government’s recent slashing of interest rates to re-invigorate investment and spending in the economy.

…on November 26th the People’s Bank of China slashed rates by more than a percentage point—the most in 11 years—to boost growth. The slowing economy has led factories to cut jobs, and there are mounting fears that the swelling ranks of the unemployed might one day take to the streets and disrupt China’s economic miracle.

An interesting point made in this article is that even continued economic growth in China does not guarantee continued job growth. Basic economic theory holds that when a nation’s output is increasing, employment is also increasing, since growth in output implies increase demand for labor. China, however, is experiencing a different type of growth today than that of years past:

China is creating fewer new jobs than it used to. In the 1980s, each 1% increase in GDP led to a 0.3% rise in employment. Over the past decade, 1% GDP growth has yielded, on average, only a 0.1% gain in jobs. Growth has become less job-intensive, so the economy needs to grow faster to hold down unemployment.

One reason for this is that the government has favoured capital-intensive industries, such as steel and machinery, rather than services which create more jobs… China needs to shift the mix of its growth from industry, investment and exports to services and consumption. To adjust the structure of production requires a further strengthening of the yuan, raising the price of energy, scrapping distortions in the tax system which favour manufacturing, and removing various shackles on the services sector.

More labour-intensive growth would also boost incomes and consumption and so help to reduce China’s embarrassingly large trade surplus.
But most important, by allowing more workers to enjoy the rewards of rapid growth, it could help to prevent future social unrest.

Discussion Questions:

  1. How does China’s current account surplus result in fewer new jobs than a growth strategy based on domestic consumption would?
  2. Why would a stronger RMB contribute to greater domestic job creation?
  3. “More labour-intensive growth would boost incomes and consumption and so help to reduce China’s embarrassingly large trade surplus” Discuss this statement.
  4. Philosophically speaking, why is there more pressure on the Chinese Communist Party to maintain high growth and low unemployment than there might be on a democratically elected party such as the Republicans in the United States?

Politics, priorities, and the Phillips Curve

FT.com / Asia-Pacific / China – Weak dollar troubles Beijing

Inflation, with its erosive effects on wealth and income, has plagued China at increasing rates since mid-2007. In February it reached an annualized rate of 8.7%, threatening to undermine China’s GDP growth rate, which has been predicted in the 8% range for this year.

As we have discussed in our our AP Econ class here in Shanghai, China’s inflation is caused by a combination of demand and supply-side factors. On the demand-side, a growing middle class has driven consumer spending to record levels recently, surpassing investment as the largest component of China’s GDP in 2007. Of course, as always, high inflation (thus low real interest rates), optimism about rising consumption in the future, and a comparative advantage in labor-intensive manufacturing (albeit a diminishing one as wages continue to rise) all combine to keep investment extremely high. Furthermore, cheap exports have helped keep demand for China’s output from abroad strong. The combination of increasing consumption, strong investment, and its trade surplus have resulted in demand-pull inflation.

On the supply-side, China has encountered additional inflationary pressures of late. Rising energy prices (mostly due to coal and oil shortages) combined with record rises in food prices (24% increase in the last year), have driven costs to firms up, shifting the aggregate supply curve leftward, further fueling inflation.

Knowing the damaging effects inflation has on income and wealth, it might be assumed that Beijing would place the utmost emphasis on taming the country’s rising prices. This, however,is not at the top of the government’s macroeconomic goals, according to premier Wen Jiabao:

On the issue of whether he would sacrifice economic output to bring down inflation, at the risk of increasing unemployment, Mr Wen indicated that growth re­mained the overarching priority. “We must ensure that our economy will grow…in order to ensure employment,” he said. “China is a developing country with 1.3bn people. We have to maintain a certain degree of fast economic growth to provide enough jobs.

”He said China needed to add about 10m jobs a year for the next five years, a lower figure than in the past whenPC the aim was growth of 15m-20m jobs a year.

The tradeoff between inflation and unemployment to which Mr. Wen refers is a text book example of the challenges faced by macroeconomic policymakers everywhere. This trade-off is illustrated in the Phillips Curve model, which shows that in the (In macroeconomics): The period of time over which wages and prices are relatively inflexible. A fall in aggregate demand will lead to unemployment and recession in the short-run. Due to the inability of the nation's producers to reduce wages paid to worker, they must lay workers off to reduce costs as demand falls.');" onmouseout="tooltip.hide();">short-run, there exists an inverse relationship between the price level and the unemployment rate.

In his words above, Mr. Wen demonstrates Beijing’s preference in the trade-off between inflation and unemployment: He’ll take inflation… Here’s why.

In case you haven’t heard, China is not a democracy. Nor is it a, ehem, “free” country. According to Alan Greenspan in his book “The Age of Turbulence”, democracy and freedom of speech act as “safety valves” in Western countries; in other words, in times of economic or political unrest, the right to gather in the streets, the right to vent frustrations through a free press and the opportunity to advocate political and economic change through the various media, all combine to prevent violent and revolutionary uprisings when times get tough economically.

Take the US for example. Times are certainly tough right now. Inflation’s approaching 4-5%, while nominal growth has nearly stagnated. Unemployment, while it has technically fallen recently, in reality has risen as hundreds of thousands of workers have given up searching for work. The bursting of the housing bubble represents one of the most massive losses of wealth in recent history. A weak dollar has meant that even cheap imports don’t seem so cheap anymore. Throw in the desperate war in Iraq, the nuclear threat from Iran, rising food prices, $110 oil and an incredibly unpopular national leader, and by some measures the country would appear ripe for revolution. However, a revolution is about the least likely thing to occur in America, because it enjoys the “safety valve” of democracy. Rather than overthrowing their government, Americans have the right to go to the pole and vote for a new one, which in all likelihood will occur this November when it seems either Barrack or Hillary stand the greatest chance and winning the White House.

Now let’s look at China. The picture’s not quite so gloomy for the Chinese right now. Yes, inflation is high, as in the US. But unlike America, China is still growing at a very healthy pace, unemployment is probably still below its natural level, the real estate markets in China’s cities are still booming, meaning the middle class residents there are experiencing leaps and bounds in terms of personal wealth. Demand for its exports remains strong, and ever more poor Chinese are finding jobs in high paying factories across the country. Investments in capital, infrastructure and education point towards a bright future of continued growth for the foreseeable future.

But wait, 8.4% is something to worry about, especially when we take into account the 24% increase in food prices. Shouldn’t Wen and Beijing be taking drastic steps to reign in this high rate of inflation? In short, NO, they shouldn’t. Because as can be seen in the Phillips Curve, to reduce inflation could result in another, far more serious problem for Beijing; rising unemployment.

It appears that Beijing’s greatest fear is a population out of work. Its goal of creating 10 million new jobs is ambitious, but in the eye’s of the government, necessary. The Chinese people do not enjoy the “safety valve” of democracy through which economic frustrations and hardships can be channeled were the country to experience a slowdown in growth and an increase in unemployment. The last time the economy faced high inflation AND high unemployment, students, workers, soldiers and tanks all gathered for an afternoon of urban warfare under Mao’s somber gaze in Beijing. To avoid such massive revolutionary movements in the future, Beijing must do all it can to insure job creation continues and growth remains strong, even if the trade-off is record high inflation.

This one passage spoken by Wen Jiabao, China’s premier, tells a vivid story about the reality of Communist dictatorship in China. Sound economic policy may go on the back burner in times of political uncertainty. Price controls, such as those on petrol in Shanghai (speaking of, the long lines at gas stations are back!), were a microeconomic example of bad economics; Beijings hesitance to seriously tackle inflation is a macroeconomic example. Holding on to power seems to be more important than stabilizing prices, at least for now.
