• Agenda
– Today: More on economic globalization

• Thursday: trade & trade agreements
Review: Economic Globalization
• Requirements for a large scale global
economy:
• 1. Inexpensive transportation & communication
– Example: Containerized shipping
• 2. International financial (money) system
– Ex: Gold standard, or system of “floating exchange rates”
• 3. Countries that are willing to participate
– Absence of legal or regulatory “barriers”
• The system of floating exchange rates
• Value of currencies is determined by the market
– Values affected by changing supply / demand for each
currency.
Review: Trade & Exchange Rates
• Who benefits if Euro goes up relative to the
US$?
• 1. European consumers – they can buy American
products cheaply
• 2. American exporters – they can sell lots more to
Europe
• Who Loses?
• 1. American consumers – European imports costs
more
• 2. European companies – can’t compete with cheap
US imports
Floating Exchange Rates
• Why do currency values “float” (change)?
• What forces affect supply and demand?
• 1. Asymmetric trade
• If a country imports more than it exports, its currency
drops
• Ex: US has a current accounts deficit with Japan
(imports more than it exports)
• To purchase Japanese goods, Americans must sell
dollars, buy Japanese Yen
– Demand drives up value of Yen relative to the dollar.
Floating Exchange Rates
• Example: The effects of asymmetric trade on
currency values
• Suppose I sell 10,000,000 computers
• Europeans will sell 7.0 billion Euros to banks in order
to purchase 1 billion US$…
– If banks (currency markets) are flooded with
Euros, supply increases, value drops…
• Currency markets don’t want more Euros
– Changing currency values often result in a trade
equilibrium
• Drop in currency limits subsequent imports
• But, we’ll discuss exceptions… (ex: China & US)
Floating Exchange Rates
• What forces affect currency values?
• 2. Asymmetric capital flows
– If capital moves into a country, currency goes up
• Ex: In early 1990s, global investors moved money into
Thailand, Mexico… raising the value of currency
– If capital moves out of a country, its currency goes
down
• Investors feared problems in Mexico, Thailand… pulled
money out
• Thai Baht and Mexican Peso dropped in value.
Floating Exchange Rates
• What causes asymmetric capital flows?
• 2. a. Interest rates
• If a country raises interest rates, its currency goes up
– Reason: Foreign investors prefer high rates
– The “electronic herd” is attracted to high rates…
• If a country cuts interest rates, its currency drops
– Investors would prefer moving money into countries where
banks pay higher interest…
– Important issue: Globalization limits the ability of
governments to control their own monetary policy
• Sometimes countries want to lower interest rates to
boost the economy…
– But can’t because it would hurt their currency
In the News: Article from 2007
• LONDON (AFP) - The dollar plunged to a record low
Tuesday against the euro, which broke through the
1.60-dollar barrier, as the unit was hit by dismal US
housing news and fresh fears over the health of the
US economy.
• Also weighing on the dollar was … the interest rate
differential between the United States and the
eurozone.
• The European Central Bank's benchmark rate, 4.00
percent, is already substantially higher than that of
the US Federal Reserve, which stands at 2.25
percent. Higher interest rates in the eurozone
makes the euro a more attractive investment
than the dollar.
Floating Exchange Rates
• What causes asymmetric capital flows?
• 2. b. Anything else that “scares” investors
– Government instability
– Concern that an economy may have problems
• Ex: Fears that Thailand was going “bust”
– Policy changes that investors don’t like
• Ex: big increase in taxes
• Shift away from free-market policies (“golden
straightjacket”)
– All of these things can cause investors to pull their
money out of a country quickly, harming currency
values.
Floating Exchange Rates
• What forces affect currency values?
• 3. Countries can intervene strategically to
alter their currency values
• Governments can sell their currency to lower its value
– They buy other currencies on global markets
• Governments can buy their own currency to raise its
value
– They spend “reserves” of gold or other currencies on global
markets
– Of course, this requires lots of money
• Mainly, big / wealthy countries do this.
Trade & Exchange Rates
• Recent news article:
• WASHINGTON (AP) -- America's
beleaguered manufacturing companies,
chafing over the loss of 2.7 million jobs over
the last three years, vowed Wednesday to
press ahead harder to get China to stop
manipulating its currency to gain trade
advantages. (Associated Press)
• Issue: China keeps value of currency low
• Aids exporters, at expense of US companies
Krugman reading: “Chinese New Year”
• Unlike the dollar, the euro or the yen, whose values fluctuate
freely, China’s currency is pegged by official policy at about 6.8
yuan to the dollar. At this exchange rate, Chinese
manufacturing has a large cost advantage over its rivals,
leading to huge trade surpluses.
• Under normal circumstances, the inflow of dollars from those
surpluses would push up the value of China’s currency, unless
it was offset by private investors heading the other way. And
private investors are trying to get into China, not out of it. But
China’s government restricts capital inflows, even as it buys up
dollars and parks them abroad, adding to a $2 trillion-plus
hoard of foreign exchange reserves.
• This policy is good for China’s export-oriented state-industrial
complex, not so good for Chinese consumers.
• My back-of-the-envelope calculations suggest that for the next
couple of years Chinese mercantilism may end up reducing
U.S. employment by around 1.4 million jobs.
Financial Flows & Exchange Rates
• Issue: Trade & financial flows have same
impact on currencies
• Asymmetrical flows cause currency values to change
– But remember: Investment flows are larger than
trade flows, and they can happen much faster
• Elwood: “pinball capital”
• Result: global investors can cause currency values to
change rapidly
• Called: market volatility (rapid change in value).
Exchange Rates & Volatility
• Capital flows and resulting currency
volatility can produce severe crises
• Example: Mexico in 1994
• Global investors bought lots of stock, investments in
Mexico over several years…
– This caused a slow rise in the peso. Not a problem.
• A minor political crisis led to panic selling in 1994
– The stock market began to plummet
• Global investors rushed to sell stocks, converted
pesos to dollars
• Result: Selling of pesos made the value of pesos
plummet!
Video
• Commanding Heights, Ep 3, chapter 7
• 5 minutes
Exchange Rates & Volatility
• Why was it bad for the value of pesos to drop
severely, rapidly?
– 1. Suddenly, imports were very expensive
• Price of gas shot up
• Businesses dependent on imports couldn’t afford
costs; potential for bankruptcies
– 2. Many Mexican companies had borrowed
money from US banks
• US banks must paid in $, not pesos
• If pesos are worth little, suddenly can’t afford to pay
loans
• Result: More bankruptcies, economic recession.
Exchange Rates & Volatility
• In the case of the 1994 peso crisis, the US
government stepped in
• Provided emergency loans, etc., to prevent massive
bankruptcy
• But, that was just a small crisis… It is clear that crises
could occur that are too large to stop so easily.
Asian Financial Crisis
• Commanding Heights Video:
• In the 1990s, foreign investors moved capital into Asia
• And, foreign banks lent money to Asian companies at
very low interest rates
– Consequence: Rapid economic growth
• Economies “heated up”
• But, capitalism is prone to boom-bust cycles…
• Companies built more factories and housing than
needed
– The “boom” ended
• But – global dynamics made the “bust” much worse!
Asian Financial Crisis
• How did globalization prompt a crisis for Asian
economies in the 1990s?
– 1. Investors pulled out quickly – affecting
currencies
• Asian currency valued dropped…
• Imports became expensive
• Companies could no longer pay off loans to foreign
banks
– Bankruptcies, unemployment…
Asian Financial Crisis
• How did globalization prompt a crisis for Asian
economies in the 1990s?
– 2. Contagion
• Worries about Thailand spread to other Asian countries
– Self-fulfilling prophecy: fear of problems caused investors to
pull out, creating real problems
• Also, many US companies were invested in Asia (or had
made loans)… Now they were losing money
– Lesson: Integrated economies mean that crises
tend to spread…
• Example: US financial crisis caused economic
disruption around the globe.

• Topic: Asian financial crisis, spillover to other
regions…

Capital Flows & the United States
• Krugman article: “Don’t Cry for Me America”
• Explains how investors are starting to pull out of the US
• Results won’t be as dire for us…
– Isn’t happening too quickly
– American companies have loans payable in US$ (if it were
Euros, we’d be in bigger trouble)
• But, still… a serious issue for the US econoomy.
