INTERNATIONA TRADE THEORIES AND POLICIES
MERCANTALISM
• Precious Metals• Zero Sum Game : One gains, one losses• Exports > Imports = Trade Surplus• Policies : Monopoly rights, restrictions• Economic System: manufacturing; rural, overseas colonies• Labor Theory of Value: Commodity is valued in relation

MERCANTALIST IDEAS VIEW CHALLENGED
DAVID HUME AGAINST MERCANTALISM
• Competitiveness Cannot Be Maintained At The Same Level
• Price Specific Flow Mechanism
• Two Countries
Country With A Surplus Country With A Deficit

ADAM SMITH AGAINST MERCANTALISM
• ROLE OF THE GOVERNMENT• (NO GOVERNMENT INTERVENTION)
– NATIONAL DEFENCE AND JUSTICE– PROVISON OF PUBLIC GOODS– INTERVENTION IN TIMES OF MARKET FAILURES
THEORY OF ABSOLUTE ADVANTAGE
ABSOULTE ADVANTAGE THEORYUSE hypothetical EXAMPLEs when you are writing your answer;
1. Labor Hours 2. 200 labor hours: 100 hours Per Each commodity
3. Domestic Production ( After Trade)

H-O Theory
• Countries will tend to specialize in the production of goods using relatively abundant factor. Comparative advantage based on resource endowments.
• More demand for that factor will be created which will increase price of that factor. Eventually they will tend to equalize with the increase in trade.

CAUSES OF DEPRECIATION
3 CAUSES
1. PERSON VISITS ANOTHER COUNTRY2. IMPORT FROM ANOTHER COUNTRY3. INVEST IN ANOTHER COUNTRY
CAUSES FOR APPRECIATION ARE THE OPPOSITE OF THESE 3
DEPRECIATION• Depreciation (weaker currency)Advantages• Producers will sell more exports• It becomes cheaper for foreigners to travel into the country• Foreign investment in domestic assets will become cheaper• There is less foreign price competition for domestic producers Disadvantages• Domestic consumers pay more for imports• It becomes more expensive to travel outside the country• It becomes more expensive to invest in foreign assets• There is less foreign competition for domestic pricing
CURRENCY APPRECIATIONAppreciation (stronger currency)Advantages• Consumer can buy more imports at a lower price• Travelers abroad can get more foreign currency• Investors can buy more foreign assets• The competition from foreign suppliers keeps domestic prices down Disadvantages• Producers will sell fewer exports• Foreigners traveling into the country will find it more expensive• Foreign investment of domestic assets will be more expensive• Domestic suppliers will have more price competition
BALANCE OF PAYMENTSA systematic record of all economic transactions with the world
• Components– Trade Account– Invisible Trade– Transfers– Current Account– Capital Account– The Overall Balance– Monetary movements– Credit and Debit Transactions– Double Entry Book Keeping
