FT.com / Asia-Pacific – Renminbi at heart of trade imbalances.

“The Americans get the toys, the Chinese get the Treasuries and we get screwed.” Thus a European Union official once characterised the pattern of Beijing accumulating US assets by selling renminbis for dollars, while nothing stood in the way of a rapid and destabilising appreciation of the euro.

In a world of freely floating exchange rates trade imbalances between countries would ultimately be reduced and eliminated. At least, that’s the belief of those advocating a floating exchange rate between East Asian currencies and the United States.

Here’s how it is supposed to work:

• Cheap labor and cheap imports from China following China’s joining the world economy 30 years ago led to a rapid increase in demand for Chinese manufactured goods in the US, creating growth, jobs, and rising national income for China.
• A trade imbalance emerges between the US and China as US spending on imports increases more rapidly than America’s  sale of exports. If the Chinese currency were allowed to float freely on foreign exchange markets, however, this imbalance would be temporary, because…
• The US current account deficit means, literally, that Americans are supplying more of their dollars in the foreign exchange market, while demanding more Chinese RMB. The forces of supply and demand would naturally lead to an appreciation of the RMB and a depreciation of the dollar.
• The weaker dollar resulting from the trade deficit with China would eventually make Chinese goods less attractive to Americans. Despite their lower costs of production, the weak dollar makes imported Chinese goods more expensive and less appealing to the American consumer.
• The strong RMB, on the other hand, makes American produced goods and services cheaper to Chinese consumers, who begin to import more from the US at the same time that Americans demand fewer of China’s products.
• Through free-floating exchange rates, a current account imbalance is eventually reduced and eliminated as exchange rates adjust to the flows of goods and services between trading partners.

A graphical version of this story is told here:

This, of course, is precisely what has NOT happened, thanks to China’s strict management of the value of the RMB. In order to keep its currency weak, Beijing directly intervenes in foreign exchange markets, “by selling renmenbi for dollars” to accumulate American assets. As seen in the next graph, such interference has the effect of keeping the dollar strong against the RMB.

As any IB student knows, the Balance  of Payments between two countries includes not only the trade in goods and services, but also the flow of real and financial assets, such as government securities, stocks, real estate, factories, and so on, between the countries. China has actively promoted a policy of acquiring such American assets, which keeps demand for dollars strong in China, and supply of RMB high in America, without creating any jobs in manufacturing or services for Americans. China has financed America’s current account deficit by assuring it maintains a capital account surplus!

Put more simply, China has exported goods and services to America, while America has exported ownership of its real and financial assets to China. This is a major area of concern for US policy makers, who would like to see a more balanced current account between the two countries, since it is the export of goods and services that creates jobs for American workers, not the sale of bonds, stocks and real estate.

Discussion Questions:

1. Why does Europe care about China’s fixed exchange rate with the US dollar?
2. Do you believe that American demand for Chinese goods would actually decline if the RMB were allowed to appreciate against the dollar? Why or why not?
3. Besides American workers and firms, who else suffers from a weak Chinese currency? How could China actually benefit from allowing the RMB to strengthen against the dollar?
4. How does China maintain the RMB’s peg against the dollar without buying large quantities of US exports?

FT.com | The Economists’ Forum | Imbalances and undervalued exchange rates: Rehabilitating Keynes

In our year 2 IB Economics class, we are beginning the part of our International Trade unit on exchange rates and the balance of trade . While the market for a particular currency reflects many of the same characteristics as a product market (i.e. upward sloping supply curve, downward sloping demand curve), the consequences of a change the price of a currency (the exchange rate) is far more powerful than a change in the price of a particular good or service in a product market.

How does the value of a country’s currency affect that country’s balance of trade with other countries? To understand this important concept, we first need to know something about the process by which currencies are exchanged when two countries trade. Let’s look at an example:

When an American consumer wants to buy an iPod that was made in China she will have to pay for it in US dollars, since that’s what she earns her wages in from selling her labor in the resource market. Apple now has the consumer’s $300, which gets split up to cover all the costs the company faced in the manufacture, distribution, marketing and sale of the iPod. Part of that $300 (say $100) will go to the manager of the factory in China where it was made.

The factory manager in Shanghai faces his own costs he must cover. He must pay rent on his factory space, interest on the loans he took out to acquire capital, and wages to the workers assembling iPods on his factory floor. The problem is, these costs are all in Chinese yuan, but he’s holding the US dollars that Apple paid him for his iPod. In order to cover his costs, the Chinese factory owner must take the $100 to a Chinese bank and swap it for RMB. The local bank that changes his money now hands the $100 over to China’s central bank (the PBOC) which prints and exchanges RMB to the bank at whatever the prevailing exchange rate is at the time.

Ultimately, China’s central bank will decide what to do with its holding of US dollars. Most of the dollars are loaned back to the United States through China’s purchase of US Treasury securities (the IOUs the US government sells to finance its deficits). China’s voracious demand for US dollar denominated assets keeps the demand for (and the the value of) dollars high on foreign exchange markets, meaning the RMB remains relatively cheap for Americans and therefore Chinese manufactured goods attractive.

China’s policy of exchange rate manipulation has upset many American politicians over the years, who often blame China for America’s shrinking manufacturing sector. A weak RMB means the cost of producing things like iPods in China is far lower than it would be in the US. By keeping demand for dollars high on the foreign exchange markets through its incessant demand for US treasury securities and other financial and real assets, while simultaneously hoarding vast reserves of US dollars in its central bank, thus keeping supply of dollars on foreign exchange markets low (see graph), China has prevented the RMB from appreciating, fueling the growth of the country’s export-manufacturing sector.

China’s currency manipulations may soon ilicit a response from the United States as president-elect Barack Obama takes office next year. Facing a recession and rising unemployment, combined with the recent appreciation of the US dollar, the pressure is on Obama to take immediate action to restore America’s manufacturing sector. According to the Financial Times blog “the Economists’ Forum”:

If the US economy takes a downturn and the dollar continues to strengthen, a resurgence of protectionist pressures is likely. This time around, these pressures could well take the form of unilateral action against competitive currencies. It is noteworthy that President-elect Obama has actively and repeatedly supported action against “currency manipulation.”

The “competitive currency” perceived to pose the greatest threat to America’s inustrial sector is certainly the Chinese RMB. Currency manipulation is a form of protectionism, which in a time of global economic slowdowns poses a larger threat than ever to both developed and developing nations’ economies alike. For this reason, the World Trade Organization may need to employ carrot and stick methods to create incentives for China to liberalize its currency controls and allow the RMB to strengthan against the dollar and other major currencies:

How would this new rule against undervalued exchange rates be incorporated in the WTO? Through negotiation. The (WTO) should place rules on undervalued exchange rates…. The US and EU have been the principal demandeurs for action by China in the past. But it is important to remember that until very recently, a number of developing countries—Brazil, Mexico, Korea, Turkey and South Africa—were affected by the competitive pressure from the undervalued (RMB). Indeed, some months ago, the Indian Prime Minister urged China to follow a more market-based exchange rate policy. For obvious reasons, more emerging market countries have not voiced their concerns, but it is possible that a coalition of affected countries could unite on this issue.

Clearly, Chinese concerns have to be addressed for any new rules to be crafted and commonly agreed… First, China’s major trading partners could pledge granting China the status of a “market economy” in the WTO contingent on it eliminating currency undervaluation and moving to a market-based system. This status would have significant value for China by shielding it against unilateral trade actions such as anti-dumping and countervailing duties by trading partners. Second, as part of radical governance reform of the IMF, which is desirable in itself, China should be offered a substantially larger voting share in the IMF commensurate with its economic status.

Discussion Questions:

1. How does China continuing to undervalue its currency threaten the industrial economies of its largest trading partners?
2. What is China’s purpose for maintaining the low value of the RMB relative to the currencies of other nations?
3. What would be a unilateral protectionist measure an Obama administration may advocate if the WTO refuses to take action against China’s currency manipulations? How would you advise president-elect Obama on the issue of whether to take protectionist action against China in the context of the current economic crisis in America?

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?

BBC NEWS | Business | Sterling rebounds from sharp fall

Americans, are you planning a vacation anytime soon? If so, why not visit LOVELY Great Britain! Why, you ask, would ANYONE want to visit the UK in during this wet, cold season? Well, here’s why I’m buying British this year:

I recently booked a Himalayan ski tour in Indian Kashmir organized by a British company. The price? 1400 GBP, which only three months ago was the equivalent of $2800 US! Today, with the newly weak British Pound, my ski trip to India will only cost me $2100*. In the span of just a few months, the dollar price of this amazing Himalayan ski adventure has fallen by $700! Naturally, Americans like myself now have an incentive to buy British!

What has caused the slide of the Pound in recent months? Here’s the complicated answer:

“The environment of very weak sentiment regarding the domestic economic picture and potential rate cuts alongside equity volatility is keeping sterling very much on the defensive,” said Jeremy Stretch, strategist at Rabobank.

Strategists get paid lots of money to say stuff that 99% of people don’t understand the first time they read it. I get paid very little money to help those people better understand it, specifically, my students. Here’s what Mr. Stretch is trying to say:

A weak economy in Great Britain leads foreign investors to believe that the Bank of England may lower interest rates in the near future. Why would Britain’s central bank lower interest rates? Because lower interest rates create an incentive for consumers and businesses to take out loans from banks and spend money in the economy, which should create new jobs and help prevent a recession in the UK.

If the bank does lower interest rates, this puts “the sterling on the defensive”, in other words, leads to a weakening of the British Pound, as foreign investors looking to put their money where they can earn a decent return on it will be less likely to save in the UK when interest rates fall. “Equity volatility” is a fancy way of saying British stocks have been performing poorly, decreasing their attraction to foreign investors. When saving in British banks becomes less attractive due to expected interest rate cuts, and buying British stocks becomes risky due to their volatility, investors turn to the safest investment in the world, which is… can you guess? United States government bonds!

So how’s this all relate to exchange rates, you ask? Let’s leave this question for readers to answer and discuss in the comments:

Discussion Questions:

1. How does the expected drop in British interest rates affect the demand for British pounds on foreign exchange markets? What does this do to the value of the pound?
2. Why does the stability and safety of US government bonds lead to a strengthening of the dollar in times of global economic slowdowns?
3. How has the recession in the United States further contributed to the weakening of the British pound?

*In fact, I’m too poor to take a ski trip to India this year, I will have to settle for the puny peaks here in the Swiss Alps!

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, 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.

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 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.

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?

More misleading economic statements from uninformed people who have never taken an economics course!

What about, you say?

I’m glad you asked!

It seems like I continuously read and hear in the American press that the United States is creating a giant wealth transfer by buying oil from other countries. Those “wealth transfer” words imply to the typical citizen that somehow our U.S. money supply is leaving our country, never to return again, and somehow our country is then poorer after the transaction and the country we imported from is now richer!

That is only a half-truth! Yes, the other country becomes richer, but we grow richer also by an equal amount! Both countries always gain economically from trade!

Let’s first get a few things straight before I elaborate: I am not happy either as gas prices rise ($3.50 a gallon in the U.S. as of this writing, although down from over $4.00 recently). I am also not happy that a fairly large share of oil purchases are from countries like Saudi Arabia and Venezuela whose loyalty to our country is certainly questionable. Luckily, the U.S. produces 40% of its own oil consumed and the other 60% consumed is imported from many different countries with 85% of our imports coming from 15 countries with Canada and Mexico being the largest two.

However, when we buy from any of these countries, both countries benefit equally and there is NO transfer of wealth. When the U.S. buys oil from any other country those U.S. dollars paid on the purchase are immediately returned to the United States and are spent almost immediately in our country since the other country cannot use our dollars in their country. What is really happening is that both countries’ citizens GAIN (not lose!) equally as we are, in essence, trading one product for another for both countries to enjoy!

Let’s use an example. Let’s say the U.S. buys 1000 barrels of oil from Saudi Arabia. At today’s price per barrel of $100 that would mean the U.S. would pay Saudi Arabia $100,000 and Saudi Arabia would then, in turn, be forced to turn around and use the paper ($100,00 USD!) on say, a bunch of iPods from Apple. Yes, the Saudi’s are listening to “I Kissed a Girl” by Katy Perry with their IPods under those smart head robes they wear! Ladies and gentlemen: that is why they call it trade: the essence of the transaction is that we have traded some of our iPods for some oil to fuel our cars and heat our homes. Both of us have gained! Katy Perry is hot on the charts and the Saudi’s “got their hands in the air”, and we can now drive to 7-Eleven for a Big Gulp and stay warm in the winter.

Also, think of it this way: when an American buys a gallon of gas the money is, in substance, going to an American business such as Apple! All spending of US dollars is spent back into our economy, and all spending of Saudi dollars (actually they call their currency the “dollar” also but it doesn’t look like ours!) benefit the Saudi economy.

Yes, trade is mutually beneficial. I would rather a warm home this winter and forego another Katy Perry song!

pintprice.com – the price of beer anywhere in the world

The theory of purchasing power parity (or PPP) holds that in the long run, the price of a particular basket of goods should adjust across countries and currencies to “cost” the same amount regardless of the currency the goods are denominated in. In other words, one dollar should buy the same amount of “stuff” in the US as it does in Mexico, China, the Netherlands or anywhere else in the world. If a dollar buys MORE in one of these countries once it’s been converted to the local currency, it implies that the local currency is undervalued and should adjust in the long run to achieve parity in the amount it can purchase in dollar terms.

One popular measure of purchasing power parity, devised by the folks at the Economist magazine’s intelligence unit, is the Big Mac Index, which measures the price of McDonald’s Big Macs in over 100 countries where they can be purchased. You can read more about this index here.

The Economist magazine recently reported on an new alternative to its own PPP index, “the Price of a Pint”:

Barflies around the world provide a useful service for their beer-drinking comrades at PintPrice.com. The prices of pints of lager are compared on the basis of anecdotal evidence from beer-drinkers around the world, so figures are regularly updated. There are some surprising results. Beer in Zambia and Burundi seems eye-wateringly expensive considering that they are among the world’s poorest countries. The French overseas départments of Guadeloupe and Martinique charge just about as much as in mainland France. Beer-loving America and Britain fall somewhere in the middle. Happily for sports fans at the Beijing Olympics, a pint in China is just $2.46.

I thought it might be useful to some of our graduating seniors planning their summer vacations or gap years. Pay close attention to the data in this table.

(source: http://www.economist.com/displayStory.cfm?story_id=11333131)

So, if cheap beer is a priority in your vacation decision, it looks like North Korea and Myanmar are ideal destinations. I must say, I am relieved to see that Switzerland, my own new home, is not in the top ten… but it is far from cheap.

The website will tell you the average price of a pint of beer in any country in the world, and then break it down to cities within each country. In Zurich, my soon to be home, a pint costs the equivalent of $6.57 US. Compared to my hometown of Seattle, Washington, where a pint goes for $3.25, that’s exactly double the price! Surprisingly, however, a pint of beer here in Shanghai goes for a shocking $5.15, more than double the Chinese average of $2.35.

Apparently, the price of beer has more to do with the local supply and demand than with relative exchange rates. Where the Big Mac Index offers a rather genuine approach to determining purchasing power parity (since the Big Mac is an identical product sold by the same restaurant facing similar costs in over 100 countries), a pint of beer is a bit more subjective a measure of PPP. Quality of beers clearly differ in locales as diverse as North Korea and Luxembourg, not to mention the incomes of beer drinkers, the number of domestic brewers, excise and value added taxes, consumers’ price elasticities of demand, and so on.

As summer vacation approaches, however, vacation planners may care to take into account the “Price of a Pint” index of purchasing power parity. Clearly, one’s dollars will go much further at bars in some places than others.

I know what you 18 year old American high school grads are thinking, “Mexico or Canada?” You’ll just have to follow the link to find out!

(Disclaimer: Mr. Welker is in no way encouraging his former students to travel to certain places based solely on the cheap price of beer there, merely to avoid places where beer is clearly out of their price range!)

BBC NEWS | Business | Q&A: Strong pound – winners and losers

Here’s another great article to help you understand the advantages and disadvantages of a strong currency. The British pound reached an all time high against the dollar late last year ($2.08 per pound, or 48 pence per dollar!!). So who are the winners and losers from a strong British pound, anyway?

Here’s a quick run-down… to read about why, click the link and read the article.

• Winners: Brits traveling and shopping in the US, US businesses, British airlines, British consumers, British drivers
• Losers: Americans traveling in Britain, small businesses in the UK, British exporting firms, British airlines, shareholders in certain companies.

Discussion Questions:

1. Why may British airlines benefit AND lose with a stronger British pound?
2. Who else will benefit from the strengthening pound that is not mentioned by the article? Refer to your notes from class.
3. Who else will be harmed by the stronger pound that is not mentioned?

Yes, but it’s a bit more complicated than it might seem at first. This podcast looks at the impact of the falling dollar on the aerospace industry, in which manufacturing for the industry’s largest firms is sourced to hundreds of smaller companies each with factories in countless countries from North America to Europe to Asia.

The recent fluctuations in the US dollar exchange rate has wreaked havoc for firms located in the US and trying to compete in this competitive market. In some cases, the outcome has been positive, but as you’ll hear, not always.

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 when 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 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.

More Bold Moves from the Fed: Business Week online ediction

Here we are, the night before our test on Monetary Policy, and good ol’ Mr. Bernanke throws me a perfect blogworthy bit of news!

The Federal Reserve announced a series of steps Mar. 16 to help provide relief to a spreading credit crisis that threatens to plunge the economy into recession: The central bank approved a cut to its lending rate to financial institutions, from 3.5% to 3.25%, and created another lending facility for big investment banks to secure short-term loans.

Global financial markets appeared to react with alarm on Sunday evening. In overseas trading, the euro made new highs vs. the dollar, U.S. Treasury futures fell, and gold futures posted new record highs at $1,009.50 per ounce.

Discussion Questions:

1. Describe briefly what the article means by “a spreading credit-crisis”. How does less lending threaten to “plunge the economy into recession”?
2. Which tool of monetary policy does the term in bold refer to? Why would financial institutions ever need to borrow from the Fed?
3. Why did the euro reach “new highs vs. the dollar” on news of the US lowering interest rates? Why did gold shoot to its highest price in history on the news?

FT.com / Asia-Pacific / China – US downturn hits Asian garment makers

Here’s a good example how a slowdown in consumer spending in the US effects manufacturers in other countries. Asian garment makers are feeling pinched not only due to less demand from American consumers, but also the weak dollar and rising costs.

“Costs are hitting us,” says Henry Tan, chief executive of Luen Thai, a large Hong Kong-based manufacturer with operations in China. “Sales to Europe are not so bad because the euro is strong, but sales to the US are very difficult.”

Chinese manufacturers have been facing double-digit annual wage increases over the past few years. More recently their headache has come from the renminbi’s appreciation, which Beijing has allowed to gather pace this year as it seeks to curb inflation.

BBC NEWS | Business | Supermodel ‘rejects dollar pay’

Currency speculators should take note… the world’s highest paid supermodel has sent a clear signal to those buying and selling currencies in the foreign exchange markets: The US dollar is NOT a good buy!

How does a woman who made $30 million in the first six months of this year send such a signal? By refusing to accept modeling contracts offered in US dollars, insisting she be paid in Euros.

The question is, why does she care what currency she’s paid in; can’t she just convert it to whatever currency she wants once she’s paid? According to Tim Harford, the “Undercover Economist”:

It seems she believes that the dollar is likely to fall in the short term, between the time a contract is agreed and the money is paid. (In the long term, who cares? She can convert her cash to any currency she likes.)

The weak dollar is clearly of concern to Americans consumers and foreign producers alike, but it’s more than likely that Gisele, while she may be the queen of the catwalk, probably knows more about striking the perfect pose than she does about behavior of foreign exchange markets.

FT.com / World – Surplus countries told to encourage demand

Is it strange at all that in a time of rising unemployment, increasing uncertainty, rising prices and falling wages, consumers are being told to spend spend spend? This is the paradox of capitalistic markets in which macroeconomic health depend on continued spending, either in the form of consumption, investment, government spending or the sale of exports to foreigners. It is this last type of spending that has begun to slow for many of the world’s developing economies, those historically dependent on strong demand from consumers abroad for their output.

The “coupling” of the economies of several developing countries to that of the United States refers to the dependence on strong consumption by Americans of their exports for domestic macroeconomic health. This symbiotic relationship, while it has contributed to a long period of high growth rates in many Asian economies, threatens to drag growth rates in several developing economies downward as Americans’ spending on imports declines.

China, one of those countries heavily dependent on export-driven growth, is now facing the prospect of a more balanced current account, which measures the difference between a countries income from exports and its expenditure on imports. Since the early ’90s, China has experienced consistent surpluses in its current account, and this will continue for the foreseeable future. Today, with falling demand for its exports from the US, China faces a new challenge:

Unwinding imbalances required domestic demand growth to slow in deficit countries but also to accelerate in countries with big surpluses from exports – such as China and oil-producing states.
It was, therefore, helpful that China planned to spend more on infrastructure, encourage household spending and allow more flexibility than previously in the exchange rate, he said.

“If the slowdown is not to dominate, we need to see a shift in relative prices to rebalance demand – that is a gradual real exchange rate depreciation of deficit countries against surplus ones,” he said.

In IB Economics, we are in the middle of our unit on international trade, in which we study exchange rate determination and the effects of an depreciation of a nation’s currency on its balance of trade. In this case, a weaker dollar will change “relative prices” by making Chinese imports more expensive to American consumers. Likewise, American goods will become cheaper to Chinese consumers, encouraging Chinese to buy more American products and fewer domestic ones.

The combined threat of falling exports and the change in relative prices that results in falling domestic demand will shift trade between the US and China towards a greater balance. According to NYT Economics columnist Paul Krugman, this rebalancing between the US and its trading partners may be just what’s needed to soften America’s economic decline.
