As the Singapore economy rebounded spectacularly this week ,the government moved to limit inflationary pressures. This was after year-on-year economic growth reached 13.1% in the first quarter of 2010.  This strong performance was related to the increased demand for electronic components and growth in the pharmaceutical industry.

The Singapore government operates a managed exchange rate regime. The Singapore dollar is pegged to a trade-weighted index of five currencies. The exact make-up of the index is kept secret, but the rate is allowed to fluctuate within a four percent target range. This ambiguity leads to less speculation by currency traders, and what is known as a basket, band and crawl method of currency management. Overtime, this has allowed the government to steadily appreciate the currency as demand for exports surged. Since 1980’s the value of the Singapore dollar versus the US Dollar has appreciated by nearly 80%.

This exchange rate mechanism is also how the government controls the rate of inflation in the small city-state. Because Singapore’s net exports make up over 100% of GDP, a subtle appreciation of the exchange rate leads to less imported inflation and less demand for exports. The effect of a 1.3% appreciation of the currency band this week, is expected to reduce inflationary pressure over the next 12 months.

The approach is something that the Chinese government is maybe looking towards. The Yuan is pegged directly to the US Dollar and has been since mid-2007. China has been able to maintain this peg by selling vast amounts of yuan to purchase US Treasury Bonds, and to thereby create large foreign currency reserves. As widely reported, the Chinese government has been under pressure to appreciate the yuan by anything up to 60% compared to the US dollar. How the government achieves this shift is complicated but may lead to a significant loss of export competitiveness and imported inflation.

However as Wei Gu from Reuters reports,

“This (Singapore) approach is not open to China, whose inflationary pressures are home-grown, and whose exchange rate looks more undervalued. Nevertheless, Beijing can learn from Singapore’s model, which offers a better balance between stability and flexibility”

Of course, there are huge differences between a city-state and the world’s third-largest economy. Singapore, whose foreign trade is three times its GDP, has to allow enough freedom in its exchange rate to achieve domestic price stability. China, where foreign trade accounts for 50 percent of GDP, that incentive is much smaller.

Moreover, China could not adopt Singapore’s approach without a one-time appreciation in its currency. Otherwise it would be hard to create a two-way trade: China currently restricts the yuan’s movement against the dollar to just 0.5 percent every day. Nevertheless, as China considers making its exchange rate more flexible without abandoning stability, the Singaporean model is worth studying.”

Discussion Questions:

1. What are the advantages and disadvantages of a floating exchange rate?
2. What are the advantages and disadvantages of a fixed exchange rate?
3. What is the common tool used by many governments to control inflation. Why can’t all countries use the Singapore approach?
4. Can a country use both Monetary Policy and a managed exchange rate to control inflation? Do trade-offs exist?
5. Evaluate the effects on the Chinese economy of an appreciation of the yuan.

When teaching international trade to high school economics students, one of the challenges is understanding the pros and cons of trade surpluses and deficits. A country’s balance of trade refers to the net flow of revenues and expenditures goods and services between the country and its trading partners. In technical terms, this is known as the current account on a nation’s balance of payments. A country that spends more on imports than it earns from the sale of exports has a current account deficit. A nation that earns more from the sale of its goods and services to the rest of the world than it spends on imports has a current account surplus.

A common impressions among students is that a trade surplus is good and a trade deficit is bad. One challenge I face in teaching this topic is separating economic terms such as “suplus” and “deficit” from non-economic, normative concepts such as “good” and “bad”. In fact, a trade surplus is not always a good thing. To illustrate, I will look at the current account balances between China and the United States. In 2007, the US ran a trade deficit with China of $258 billion. While the US imported $321 billion of Chinese goods and services, it only earned $63 billion from the sale of exports to China. To most students, it would appear that China is “winning” in the game of trade, since it has such an enormous trade surplus with the United States. This, however, is not necessarily the case.

One way of looking at trade balances is that a nation with a substantial current account surplus is actually consuming less of its own output due to the high demand from abroad. As mentioned above, in 2007 Americans spent $321 billion on Chinese goods and services. China only produced $3.2 trillion of goods and services that year, meaning Americans actually consumed over 10% of the stuff produced in China! This represents Chinese output that is NOT being consumed by the Chinese. Additionally, since China imported far less from abroad than it sold, Chinese output being consumed abroad is far from made up for by Chinese consumption of foreign output. While this may sound like a good deal from the perspective of producers, who have a larger market due to trade, from the perspective of Chinese households it means they are consuming less than they are producing as a nation!

One of the goals of macroeconomics is to increase the standards of living of the nation’s people through an increase in the consumption of goods and services. In this regard trade deficit countries are actually better off than trade surplus countries, since they are actually consuming MORE than they are producing as a nation! A trade deficit country gets more than it gives, in a way, which sounds pretty good when if you consider total consumption to be an end in itself. A trade surplus country, on hte other hand, gives the rest of the world more than it gets in return (in terms of goods and services, that is).

Another consequence of running a large trade surplus is the build up of foreign exchange reserves. China, for instance, held over $1.3 trillion USD in its central bank in 2007, representing an enormous level of savings for the Chinese people, since these are dollars earned by the people of China (from their export sales to America), but not spent. These reserves represent a form of forced savings on the people of the nation.

The average Chinese consumer is also made worse off because the governments’ US dollar reserves are held intentionally to keep the value of the dollar high, thereby keeping the price of American and other nation’s imports prohibitively high for Chinese consumers. In this regard, China’s 50% national savings rate is a form of financial tyranny by the government perpetrated against the Chinese people, who, as consumers, would be much better off if the RMB were allowed to appreciate and imported goods and services could be more easily and affordably attained by Chinese households. Employment in the export sector might suffer but falls in exports would likely be made up for with gains in domestic consumption, meaning the overall effect on employment is likely to be mild upon a reductions in China’s trade surplus.

Furthermore, in order to maintain China’s trade surplus the Chinese government must keep the RMB weak. As already mentioned, one way it does this is by holding its US dollar reserves to keep the supply of dollars on foreign exchange markets low and its value high. Another way the Chinese central bank manipulates its currency is by constantly changing the level of interest rates to limit or encourage foreign capital flows into or out of the country, since such flows affect the Chinese currency’s value. If the Chinese central bank and government were to adopt a flexible exchange rate policy, which would help reduce the country’s trade surplus with the United States, this would allow the central bank to use monetary policy in the way it is meant to be used: to stimulate or contract the level of domestic consumption and investment. This week US Fed chairman Ben Bernanke spoke to the US Senate about China’s exchange rate controls, and made a similar point:

“Most economists agree the Chinese currency is undervalued and has been used to promote a more export-oriented economy. I think it would be good for the Chinese to allow more flexibility in their exchange rate.”

Letting its currency, the renminbi, appreciate would give China’s central bank more flexibility in monetary policy and help stimulate domestic demand and consumption, Mr. Bernanke said

China’s trade surplus does not necessarily benefit the country as a whole. Surpluses do keep export sector employment high, but result in a lower overall level of consumption among Chinese households and impose a higher than necessary level of savings on the nation. More balanced trade would increase the level of imported goods and services in China, increase real incomes as the value of the nation’s currency rises, and also allow for more inflows of foreign capital from abroad, further stimulating growth in China’s domestic economy.

One feature of Economics in Plain English several students and teachers have found helpful over the years is the Econ Help Desk, where readers can get questions about basic economic concepts answered personally by me.

Recently I received the following email from an AP Macroeconomics teacher in the United States:

I have a question about graphs that illustrate how trade preferences (specifically Supply and Demand shifts), affect P, Q and Pe on Supply-Demand GRAPHS of Currency Exchange.

In teaching my AP Macro students about this concept, I have reached a gap in our full understanding how to graph the Supply and Demand of Yen, or Euro (Price in USD).

For example, if the Price levels rise in the U.S., relative to Japan’s, and consequently, the U.S. demands more Japanese cars and stereos, the only label that we ever see for the x-axis is “Q” or Quantity, or Qe, a vertical line that represents the starting “market clearing price”, of .01USD=1Y. When DEMAND or SUPPLY shifts, the only change that I ever see labeled on the graphs is the Y-Price in USD of Yen, but descriptions simply talk about the Y=1.

When Demand or Supply shifts (in response to increased demand for Yen), and there is a new higher or lower USD Price for Yen, respectively, does the vertical line for Q simply shift outward (continuing to represent Y=1) at whatever the new Price Equilibrium becomes (simply meaning just more “1s” of them in circulation (at each new Pe market-clearing point)?

Thanks

Here is my response:

Hello, I will try to address your questions below.

Exchange rates can be determined by several factors, including relative price levels, relative interest rates, tastes and preferences of domestic and international consumers, relative income levels at home and abroad and speculation by currency traders. As you say, an increase in the price level of goods produced in United States (say, Fords), ceteris paribus, should lead to an increase in demand among American consumers for goods produced in Japan (say, Hondas), which now appear relatively cheaper. Demand for Yen increases among American households who wish to buy Japanese goods. The USD price of Yen then rises in the Yen market. Since Japanese holders of Yen now receive more USD for each Yen, they will provide more Yen (this is another way of saying with an increase in demand for Yen, the quantity supplied of Yen increases).

Theory would say that there is no increase in the supply of Yen following an increase in Demand by American consumers, only an increase in quantity supplied. The Yen clearly appreciates, as the USD/Yen exchange rate rises. Now, there is another side to this story. The Yen market refers to the market for Yen in the United States. Yen will appreciate in the United States. Simultaneously, USD will depreciate in Japan, as Americans buy more Japanese goods, they are supplying more USD in the USD market in Japan. Here the “price” or the exchange rate is Yen/USD. The Yen price of a USD will fall as the supply of USD increase as Americans exchange their dollars for Yen to buy the relatively cheap Japanese goods.

The “market-clearing price” in foreign exchange markets is the exchange rate that prevails in a floating exchanged rate system where exchange rates are determined solely by supply and demand by international consumers, investors, government, banks, and firms. Assume the Yen is trading for $0.01. If , following inflation in the United States and the corresponding increase in demand for Yen, the value of the Yen remained at $0.01, then the quantity demanded for Yen would exceed the quantity supplied. There would be shortages of Japanese goods in the United States, as Japanese goods are in greater demand yet their prices have not risen. In order to “clear the market” so to speak, the exchange rate must rise, to say $0.012. Now, a Yen’s worth of goods “costs” Americans 20% more than previous, making them less attractive over time. Likewise, a dollar’s worth of goods “costs” Japanese consumers 20% less, since the dollar is weaker in Japan.

As you can foresee, the floating value of the Yen should lead to relatively balanced trade between Japan and the US. The US current account will initially move towards deficit as inflation makes American goods more expensive, however, as demand for Japanese goods increases, the value of the Yen rises making Japanese goods more expensive, which will eventually reduce their appeal to American consumers who will once again begin consuming more American goods and importing less. Japanese will notice the weaker dollar makes US imports cheaper and begin importing more American products. The US current account should remain  balanced in the long-run in a floating exchange rate system.

I don’t know if you’ve had a look at my study guides on exchange rates and balance of payments, but those may help clarify graphically what I describe above:

• Unit 4: Exchange Rates
• Unit 4: Balance of Payments

I hope this clarifies your understanding of how relative price levels help determine exchange rates!

Argentina’s reserves and its debts: Central Bank robbery | The Economist

I received the following email from an Econ teacher who wonders if I had any insight on a question posed by one of his students:

The email reads: “I have alittle query i was hoping you could help clear up for me..a year 13 student has asked a question relating to Argentina’s prime minister, Cristina Fernandezde De Kirchner’s, decision to sell the central bank’s dollar reserves to fund part of the country’s decifit against the advice of the director of the central bank who resigned.”

The student’s question is on the following passage from the Economist article above:

Fernández (Argentina’s president”) justified her raid on the reserves by saying that the Central Bank had more than it needed, because they exceeded the size of the monetary base. Economists disagree about what is an appropriate target for the reserves, but Mr Redrado’s view is that a highly dollarised emerging economy like Argentina’s needs an abundance of Treasury bonds (the form in which most reserves are held) as insurance. Even if Ms Fernández might find support from some economists for her argument, her plan to swap the dollar reserves for a non-transferable government bond would not.

The student’s question is: “I do not know what a monetary base is, nor why Argetina needs treasury bonds.”

This article really caught me off guard at first as well. One thing I love about the Economist newspaper is its use of economic jargon that requires a real understanding of the subject to be able to interpret. The first time I read the article, I will be honest I was completely confused as to what the Argentinean president was up to. But after some reflection and rough sketches of graphs on scrap paper, I think I have “translated” the article’s jargon into plain English.

Below is my reply to the teacher and his student:

Hello,

The president of Argentina wants to sell the country’s US dollar reserves, which are held in the form of US treasury bonds, and then use the US dollars she receives to buy Argentinean government bonds in order to finance her own government’s budget deficit. In essence she wants to swap Argentina’s central bank reserves of US debt (considered a very stable and safe asset due to America’s low inflation rate and relative solvency of the US government) for Argentinean government debt (less stable and safe, especially in the wake of the country’s 2002 default on its debt). Argentina’s central bank would then hold fewer transferable, stable US bonds and more “non-transferable”, Argentinean government bonds. And since the bonds represent Argentina’s government debt, the country as a whole reduces its assets and increases its liabilities.

It is important for a developing country like Argentina to keep large reserves of US dollar-denominated assets (i.e. US treasury bonds) in reserve in order to assure foreign investors that the country would be able to stabilize its currency’s value in the face of a currency crisis such as that which Argentina experienced in 2001-2002. If the value of the peso began to decline on foreign exchange markets (due, for instance, to a decline in international investor confidence in the government’s ability to pay the interest on its foreign debt or inflation fears caused by excessive monetary growth or government spending) then the central bank could use its large dollar reserves to intervene in the forex market and stabilize the value of the peso, reestablishing investor confidence and maintaining the government’s ability to attract foreign creditors in the Argentinean bond market. A collapse of the peso would have ripple effects throughout Argentina, driving up imported products and raw materials and causing spiraling inflation, forcing the government to print more money to finance its budget in the face of falling demand for its debt in domestic and international bond markets.

Argentina must be sure to keep its balance sheet (i.e. its liability to asset ratio) in check. Its assets are US government bonds, its liabilities are the Argentinean bonds it issues to finance its budget deficits. If this ratio become too heavy on the liability side, foreign investors and speculators will lose confidence in the both peso and the Argentinean government’s solvency and dump their holdings of Argentinean currency, assets, and bonds, driving interest rates through the roof and the exchange rate through the floor, grinding the economy to a halt.

The article says,

Argentina’s economy is on course to rebound this year and grow at 3-5%. But the government is spending money so fast that this growth will not finance current spending on its own, says Daniel Marx, a former finance minister. Ordinarily, a government faced with a shortfall would turn to domestic and international bond markets. But this has been difficult since Argentina defaulted in 2002.

The country cannot count on private creditors to make up its budget shortfall, so the president is planning to finance her country’s deficit by buying Argentinean bonds with the country’s own US dollar reserves. Such behavior concerns economists because it could send a message to international investors that the country is on the path towards another unsustainable build-up of debt that could culminate in another default and economic collapse. The article is a word of caution to the president that all leaders should heed: balanced budgets are a good idea, and debt is dangerous!

Related Unit: IB Economics Unit 4.7 – Balance of Payments

Topic: The Marshall Lerner Condition and the J-Curve

Learning Goals/Objectives:

• For students to understand that the levels of price elasticity of demand for a country’s imports and exports determines whether a depreciation or devaluation of the country’s currency will move the nation’s balance of payments towards a surplus or a deficit.
• For students to understand the impact of time on the effect of a depreciation or devaluation of a nation’s currency on its balance of payments in the current account.
• For students to evaluate the argument that a country will always benefit from a weaker currency.

Success Indicators:

• Students will present their PowerPoint presentations of their exchange rate research, explaining how elasticity, exchange rates, and the balance of payments are related.

Country A: ____________________ and ______________________

Country B: ____________________ and ______________________

Questions the PowerPoint should answer:

1. What is the Marshall Lerner Condition? Why is it important to consider the price elasticities of demand for exports and imports when examining the impact of a change in exchange rates on the current account balance?
   
2. Describe two periods of time from your line graph: One in which your country’s currency strengthened and one in which it weakened against the other country’s currency.
   
3. Using your knowledge of economics, explain TWO factors that may have caused the changes you have identified.
   
4. Given the changes identified, what would you predict would be happening to your country’s current account of the balance of payments over the three periods you specified above?
   
   1. Period 1: _______________________
      
   2. Period 2: _______________________
5. For both the periods of change, explain the impact of the change in exchange rates on the following:
   
   1. a firm that imports its raw materials from the other country
      
   2. a firm that exports its finished products to the other country
      
   3. consumers who buy imports from the other country
      
   4. a firm that produces good for the domestic market and competes with firms from the other country
      
6. Consider the impact of changes in the exchange rate on amount spent on imports and the revenue earned from exports (and thus, the current account balance). Assume the following for the three periods from your chart:
   
   1. Period 1: The price elasticity of demand for imports is 0.35 and the price elasticity of demand for exports is 0.55.

      2. Export revenue will __________________
      3. The current account will move towards DEFICIT or SURPLUS (identify which)
      4. Is the Marshall Lerner Condition met? Explain
7. Think about the period in which your country’s currency weakened. Assume that the currency remains weak. How would the balance on the current account change over time following the depreciation of the country’s currency. Draw a J-Curve and explain its shape, referring to your country’s currency.
8. Look at the following article: ‘How Far Will the Dollar Fall?’ by Richard W. Rahn.
   1. Explain how the fall in the dollar might help to reduce the US trade deficit.
   2. Assess Dr Rahn’s argument that taxation and regulation are the principle causes of the potential for the limits to growth in the world economy.

You’re now prepared to consider the elasticity implications for balance of payments. Test your own understanding of the Marshall Lerner condition by answering the following IB questions:

1. With reference to the Marshall-Lerner condition, explain how the depreciation of a country’s exchange rate might affect its current account balance. (Total 10 marks)
2. An economy is currently experiencing a deficit on the current account of its balance of payments. The government is considering either allowing the exchange rate to fall or reducing aggregate demand. Evaluate the relative advantages and disadvantages of these two policies. (15 marks)
3. Explain how, in theory, balance of payments deficits and surpluses on current account are automatically adjusted under a system of flexible exchange rates. Illustrate your answer using supply and demand analysis. (Total 10 marks)

The above lesson was inspired by the Biz-Ed activity “International Trade: The Falling Dollar or Rising Pound?”

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?

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!

In the last three months, the Japanese Yen has appreciated 15% against the US dollar. At the same, the dollar itself has appreciated 25% against the euro.

The appreciation of these two major currencies seems strange in a time when both country’s economies are experiencing major slowdowns. In most cases, currencies appreciate when one of two things happens:

• If foreigners demand more of a country’s exports, demand for its currency drives up its value, causing appreciation.
• If a country’s interest rates rise relative to other country’s, then demand for its currency rises as investors want to buy assets in that country to earn the higher interest rates.

Lately, however, the Yen and the Dollar have seen staggering rises in the absence of rising exports or rising interest rates in Japan or the US. So what IS causing the rapid and drastic appreciation of these two currencies? The Economist newspaper explains:

Many investors have been following a version of the “carry trade”, borrowing money in a low-yielding currency. All they had to do was earn a higher return from assets than the cost of their financing. Since the two big currencies with the lowest yields over the past year have been the dollar and the yen, those were the natural ones to borrow.

When asset prices fall, however, this strategy is disastrous. Investors dash to sell assets and repay their debts. Since those debts were incurred in dollars and yen, that means they have to buy back those two currencies—hence their sharp recent rises.

In the midst of today’s global financial meltdown, it seems that every day, phenomena new to mainstream economic theory are being witnessed. It would seem that from now on, when we learn about the determinants of exchange rates, we may have to take a look at the “carry trade” example.

In this case, it would seem, LOW interest rates combined with falling stock prices can lead to a currency’s appreciation. An investor looking to make a deal would borrow Yen from a Japanese bank charging low interest rates, convert it to, let’s say Brazilian real, to buy stocks in a Brazilian company. As long as the stocks gain value at a rate higher than the interest rate in Japan, the investor is making an easy profit. He can pay back the money he borrowed from Japan at the low interest rate, earn a high return on his investment in Brazil, and pocket the difference.

The problem arises when the value of the assets the investor has bought in Brazil begins to fall. With stock markets plummeting between 20-50% this year in most countries, asset values have fallen through the floor, meaning those investors who borrowed yen to buy foreign assets have rushed to sell the falling assets as quickly as possible to pay back their Japanese lenders before it’s too late. This causes a huge increase in demand for Yen on foreign exchange markets in a very short period, hence the yen’s appreciation.

Recently, the Yen and USD have managed to appreciate for a reason not conventionally understood. The rapid and drastic appreciation of these currencies is further exacerbating the weak aggregate demand in Japan and the US. A strong currency, while good for consumers for whom imports appear cheaper, can have debilitating effect on a country’s export sector. Not surprisingly, both the US Fed and the Japanese central bank have both cut interest rates in the last week in the hope of slowing their currency’s appreciation and protect export demand.

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 / World / Americas – US economy threatens Dominican Republic

Trade based on comparative advantage… the theory originally articulated by Adam Smith, later fine-tuned by David Ricardo, the theory that suggests that if each nation specializes its economic activity on the products for which it faces the lowest opportunity cost, then trades with its neighbors, total world output and efficiency can be maximized: today this theory represents the philosophical underpinning of all free trade agreements signed between and among the nations of the world.

Through trade, countries can exchange their extra output with other nations for the goods specialized in by others, enabling all nations to enjoy a level of consumption beyond what they’d be able to achieve if they tried to produce all goods domestically.

For many developing countries, with their abundance of either land or labor, comparative advantages tend to lie in either agricultural goods or low-skilled manufactured goods. Since global prices for food are highly unstable and dependency on healthy harvests, good weather, and stable rainfall are all highly risky endeavors for a poor country, developing nations prefer to foster the growth of manufacturing sectors in their path towards economic development.

Strategies for economic growth available to developing nations include export-oriented and inward-oriented growth. A country like the Dominican Republic, the largest economy in the Caribbean, has pursued a predominantly export-oriented growth strategy, promoting through “free zones” the growth of a textile industry aimed at producing goods for consumers in developed countries, primarily the US.

To the Domincans, producing textiles for export to America has successfully given the people of this poor nation a grip on a rung of the ladder towards economic development. The import of capital has taken previously unproductive workers out of agriculture and put them into an industry where productivity, thus income, has risen, leading to improvements in living standards. Export-led growth, however, runs some serious risks of its own, as is being realized by the people of the Dominican Republic today.

It had been clear for some time that Luis Caraballo’s textile factory, in one of the Dominican Republic’s largest “free zones”, was struggling.

Finally, last December, he closed the factory gates for the last time: cut-throat competition from China and Vietnam, a weakening US dollar and unsustainable costs had become too much.

Once a hot destination for American companies looking for a cheap place to “off-shore” production of labor intensive textiles, the Dominican Republic today faces new competition, and is finding its comparative advantage slip slowly away from textiles…

The Dominican Republic depends heavily on the US, which is the destination of more than 85 per cent of exports. But textile exports – these days accounting for less than a third of total exports – fell by 32 per cent over 2007.

Although other countries in the Caribbean are also suffering from Asian competition – with Chinese textile exports to the US tripling between 2000 and 2005, while Vietnam’s multiplied almost 117 times – the Dominican Republic has been worst hit.

Here’s the thing: a nation’s comparative advantage may shift over time (from land to labor to capital intensive goods) as the structure of the global economy evolves. Once an economy like the Dominican Republic’s has undergone a period of structural adjustment, away from agriculture and towards industry, the flow of low wage workers from farm to factory begins to slow to a trickle, leading to rising wages and increased competition from countries with more abundant supplies of cheap labor.

The challenge for policy makers is to manage the structural changes as they come, minimizing the deleterious impact such global shifts of productive resources has on the citizens of a country like the D.R. Clearly, it is in the country’s interest to prepare its citizens for a “new economy”, one in which skilled labor will play a larger role. The problem is, this requires a solid education system, which the D.R., it turns out, does not yet have:

There is widespread acceptance of the need to develop a better-educated workforce, but so far education spending has been inadequate.

“The government simply doesn’t have enough resources,” said Mr Montás. About 40 per cent of its budget goes on debt obligations and another 15 per cent is dished out through subsidies. Just 1.5 per cent goes towards education.

It also turns out that this is a balance of payments story:

Mr Montás calculated that for every percentage point the US economy contracted, the Dominican Republic’s GDP would shrink by 0.4 per cent.

Not only will exporters be hit, but also the huge tourism sector and remittance flows…

One possible result of the decline in exports and flows of remittances from the US will be a depreciation of the D.R. peso, as demand for pesos by Americans falls. A weaker peso might make the country’s exports attractive once again, assuming the exchange rate is allowed to adjust on foreign exchange markets. A weaker peso should help slow the decline in the D.R.’s exports to the US, at least until new competition emerges, perhaps elsewhere in Asia, maybe even from Africa or other Latin American countries.

In all likelihood, given the increased competition from Asian textile manufacturers, continued economic growth in the Dominican Republic will depend on the country’s ability to educate and train its workforce to adapt to a more capital, technology and information-based economy, which, if successful, will eventually lead to rising incomes and higher standards of living for the people of the this rising Caribbean nation.

Comparative advantages evolve with the emergence of new competition among developing and developed countries. The negative impacts this evolution has on a particular economy can be managed if wise policy actions are taken to assure a country’s workforce is educated and trained to participate in tomorrow’s economy, rather than yesterday’s or today’s.

I like this commercial. It teaches us nothing about economics, but it’s amusing and brings some light to a rather dismal outlook for the US economy and falling dollar…

FT.com / World – American dream hit by dollar’s decline

Ever wonder if there was a connection between the strength of a country’s currency and the flow of immigrants into that country? No? Me neither… but interestingly it appears that there is a direct relationship between these variables. The weaker a country’s currency, the fewer immigrants cross its borders to find work. Here’s why:

Migrant workers are choosing to move to Europe, Australia or Canada instead of the US in order to protect the purchasing power of the money they send home to their families, according to one of the world’s leading experts on remittances.

The shift is a result of sharp falls in the value of the US dollar against other international currencies, many of which have been boosted by the rise in commodity prices.

This news may make some American’s happy, since it could mean more opportunities for the American workers who may have lost their jobs during the current recession. This, however, may not be the case. It turns out that much of the decline in immigrant workers is in high skilled fields for which demand for workers in the US remains high even in times of recession. According to the article, “the trend was especially notable among skilled workers, such as doctors, nurses and information technology specialists”.

A decline in the inflow of high skilled workers may actually make Americans worse off. I have blogged about the shortage of American workers in fields such as engineering, software design, and natural gas rig technicians,and I don’t think many Americans would argue that health care in America is already too cheap, so I suspect that more doctors and nurses would be desired.

A weak dollar has many effects on America. In some ways, it makes the country better off. As I have blogged about here, a weak dollar should lead to more balanced trade, a boom for US manufacturers, and an increase in exports, all related, of course, to the relative decline in prices of US goods to foreign consumers. But a weak dollar may in fact do more harm than good, one reason for which is explained here: skilled foreign workers whose talents are in strong demand in the US are moving more and more to European markets to find work.

Anti-immigration hawks may be cheering, but American consumers may start rearing as high-skilled labor shortages drive up wages and prices in the markets Americans most depend on today: health care, energy and technology.

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?

Inflation Reality Check(The Korea Times)

Harvard Economist Kenneth Rogoff points out that inflation is a major problem in many of the world’s largest economies today:

Inflation in Russia, Vietnam, Argentina, and Venezuela is solidly in double digits, to name just a few possibilities.

Indeed, except for deflation-ridden Japan, central bankers could meet just about anywhere and see high and rising inflation. Chinese authorities are so worried by their country’s 7 percent inflation they are copying India and imposing price controls on food.

Even the United States had inflation at 4 percent last year, though the Federal Reserve is somehow convinced that most people won’t notice.

Usually, inflation can be combatted with restrictive monetary policy, or the selling of bonds on the open market, which reduces the money supply, raises interest rates and slows down consumption and investment, and thus the pressure on prices in the economy. Today, however, the US Fed is in the process of expanding money supply and lowering interest rates, in an attempt to avoid a recession at home.

In a world of isolated economies, the US monetary policy would only affect the US economy; however, today the US economy finds itself intertwined in complex ways with other economies of the world.

America’s inflation would be contained but for the fact that so many countries, from the Middle East to Asia, effectively tie their currencies to the dollar. Others, such as Russia and Argentina, do not literally peg to the dollar but nevertheless try to smooth movements.

As a result, whenever the Fed cuts interest rates, it puts pressure on the whole “dollar bloc” to follow suit, lest their currencies appreciate as investors seek higher yields.

Looser U.S. monetary policy has thus set the tempo for inflation in a significant chunk ? perhaps as much as 60 percent ? of the global economy.

The reason other countries must mimic US monetary policies has to do with exchange rates, which many countries try to peg to varying degrees to the value of the dollar. One of the determinants of exchange rates is relative interest rates between countries. If the US lowers interest rates, and a country like Argentina keep rates high, global investors looking for a return on their savings will take their money out of US savings accounts and deposit it in Argentinian savings accounts, where they can earn a greater interest rate. In order to save in Argentina, investors need to convert their dollars to Argentinian pesos, driving up demand for pesos and the dollar/peso exchange rate. A stronger peso could have negative impacts on demand for Argentina’s exports as they become more expensive to foreign consumers. In order to avoid appreciation of its currency and declining demand for its exports, Argentina is thus forced to lower its own interest rates as the Fed cuts those in the US.

When you consider that much of the world adjusts its currency in relation to the dollar, you can see how an easy money policy in the US could lead to falling interest rates worldwide, triggering all sorts of new consumption and investment, driving price levels ever higher.

There is hope for curing the inflation problem. Relief may come at a price for Americans, however:

If the U.S. tips from mild recession into deep recession, the global deflationary implications will cancel out some of the inflationary pressures the world is facing.

Global commodity prices will collapse, and prices for many goods and services will stop rising so quickly as unemployment and excess capacity grow.

Of course, a U.S. recession will also bring further Fed interest-rate cuts, which will exacerbate problems later. But inflation pressures will be even worse if the U.S. recession remains mild and global growth remains solid.

Once again the Fed’s challenge of balancing unemployment, inflation, growth and recession is made clear. The choice of several major world economies to affix their currencies’ values to that of the dollar makes the challenge ever more dire for Mr. Bernanke.

Discussion Questions:

1. If a US interest rate cut is not matched by countries that tie their currency to the dollar, what would happen to the value of those countries’ currencies?
2. Why are lower world interest rates inflationary?
3. What will happen to the value of the Euro if the ECB does not start cutting interest rates soon?
4. Why might a US recession counter the inflationary pressure caused by rising food and energy prices and loose monetary policy in the US and other nations?
