Unit VII (Absolute and Comparative Advantage)

• Absolute Advantage:

 -Individual- exists when a person can produce more of a certain good/ service than       someone else in the same amount of time (or can produce a good using the least   amount of resources.)

·         National-exists when a country can produce more o a good/ service than another county can in the same time period.

• Comparative Advantage:

-A person or a nation has a comparative advantage in the production of a product when it can produce the product at a lower domestic opportunity cost than can a trading partner.

                                       

• Specialization and Trade:

-Gains from trade are based on comparative advantage, not absolute advantage.

• Examples of Output Problem:

- per acre 

-miles per gallon

-word per minute

-apple per tree

-television produced per hour

• Examples of Input Problems:

-number of hours to do a job

-number of acres to feed a horse

Unit VII (Foreign Exchange)

• Foreign Exchange:

-  Buying and selling of currency-Any transactions that occurs in the balance of payments necessitates foreign exchange-Exchange Rate (ex): is determined in the foreign currency markets

• Changes in Exchange Rates:

-Exchange rates (e) are a function of supply and demand for currency- an increase in the supply of a currency- a decrease in supply of a currency will increase the exchange rate of currency- increase in demand for currency will increase the exchange rate of currency- decrease in demand for a currency will decrease the exchange rate of currency
Appreciation and Depreciation:·         Appreciation of currency occurs when exchange rate of that currency increases (e^)
·         Depreciation of a currency occurs when the exchange rate of that currency decreases

• Exchange Rate Determinants:

-Consumer tastes-Relative income-Relative price level-Speculation
-Exports and Imports:·         Exchange rate is a determinant of both exports and imports
·         Appreciation of the dollar causes American goods to be relatively more expensive and foreign goods to be relatively cheaper, thus reducing exports and increasing imports
·         Depreciation of the dollar causes American goods to be relatively cheaper and foreign goods to be relatively more expensive thus increasing exports and reducing imports

• Floating/ Flexible Rates:

Depends upon supply and demand of that currency vs. other currenciesVery sensitive to business cycle / provide options for investments
Fixed Rates:Based on a country's willingness to distribute currency and to control the amount
As two currencies trade:1.    One supply line will ∆, the other demand line will ∆.
2.    They will move in the same direction
3.    One currency will appreciate, the other will depreciate
