Teaching the Terms

• Exchange rates• Appreciate• Depreciate• Purchasing power parity• Nominal values• Real values

Foreign Exchange Market

• Derived demand• Currencies are bought and sold• Largest financial market in the world• Operates 24 hours a day

Nominal Exchange Rates

• Rate at which the currency of one country can be exchanged for the currency of another country

• Depreciate = Weaken = Lose value• Appreciate = Strengthen = Gain value

Exchange Rates

• One exchange rate is the reciprocal of another exchange rate– If €1 = $2.00, then $1 = €0.50

• As the exchange rate fluctuates, the value (or strength) of each currency is affected

• When one currency strengthens, the other weakens

Weakening Dollar / Strengthening Euro

Value of

•$1 = €1.00 (or €1 = $1.00)

U.S. dollar

•$1 = €0.67 (or €1 = $1.50)

Falling

•$1 = €0.50 (or €1 = $2.00)

Weakening Euro / Strengthening Dollar

Value of

•€1 = $2.00 ($1 = €0.50)

Euro

•€1 = $1.50 ($1 = €0.67)

Falling

•€1 = $1.00 ($1 = €1.00)

Exchange Rates in the Short Run

• Model with supply and demand graph– Quantity of dollars– Price of a dollar in a foreign currency

• Factors affecting supply of dollars– American purchase of goods and services produced abroad– American investment in foreign assets

• PPP implies that the real exchange rate will always be 1
