Unit 7

4/21
Balance of Payments
  • Sum of all transactions between nation's residents and residents of all foreign countries.
  • Statement shows all payments a nation receives from foreign countries and all the payments it makes to them.
  • Example : Exports and imports of goods and services
  • Example: Interest and dividend received or paid abroad 
Current Account
  • Record of all the imports and exports
  • Record of services refers to tourism, transportaion, engineering, etc.
  • Balance of Trade- combo of imports and exports of goods/services
  • B.O.T Deficit - imports > exports
  • B.O.T Surplus - imports < expoorts
Capital Account
  • Purchases of real or financial assets and the correspondin flow of monetary payments that accompany them.
  • Example : Foreign firm buys an office building or U.S govenment security. Those would be exports in return for payments of foreign currency
Official Reserves
  • Central banks of nations hold quantities of foreign currency called Official Reserves
  • These Reserves can be drawn upon to make up any net deficit between capitol and current goods
  • All three accounts must equal zero
  • However there can be an ambiance between capital and current goods. Deficits are drawing down of foreign currency. Surplus is the building up  in Foreign Currency
4/23
Foreign Exchange Market
- Supply of the dollar comes from US citizens, banks, and industries wanting to purchase foreign goods, investments, assets, and to make transfer payments to foreigners
- Demand of the dollar comes from foreigners, banks, and industries wanting to purchase our goods, investments, assets, and to make transfer payments to the US
*Dollar appreciates
- Demand increases, supply decreases
* Dollar depreciates
-Demand decreases, suply increases



-Five determinants of supply and demand in the foreign exchange market
  1.  Change in buyers taste
  2. Change in relative income
  3. Change in relative prices
  4. Change in interest rates
  5. Change in expectations
-Fixed rate Exchange
  • Determined by the government 
- Flexible/floating exchange rate
  • Determined by market forces such as supply/demand, little or no government intervention
4/24
Absolute/ Comparative advantage 
-Absolute Advantage : the ability of a party (an individual, or firm, or country) to produce more of a good or service than competitors, using the same amount of resources.  
-Comparative Advantage: A country makes goods at low opportunity cost, both countries benefit from trade.  

- Terms of Trade: Ratio of exports to import prices
  • based on comparative advantage
- Specialization allows world output to grow and increase nation's productivity.
  • Produces larger inputs of goods and services

Unit 6

Economic Growth
  • Economic Growth = Shift in Production Possibilities Curve outward
  • Economic Growth = Shift in the Long Run Aggregate Supply Curve to the right
- Why growth rates differ among countries:

  • Rates of savings
  • Foreign Investment
  • Education
  • Infrastructure
  • Research and Development
  • Political Stability
  • Protection of Property Rights
  • Economic Freedom versus Excessive Government Intervention
-Human Capital
  • People are a country's most important resource. Therefore human capital must be developed.
  • Education
  • Economic Freedom
  • The right to acquire private property
•People are a country’s most important resource. Therefore human capital must be developed.
•Education
•Economic Freedom
•The right to acquire private property
•Incentives
•Clean Water

Economic Growth

Unit 5

3/31
-Short run:timed to short for wages to adjust to the price level
  • Rationale: workers may not be aware of changes in their real wages due to inflation, and having adjusted their labor supply decisions in wage demands accordingly
-Nominal wage: amount of money received per hour, per day, per year

-Long Run AS : time long enough for wages to adjust to the price level
  • Key Assumption :
    • Represented by a vertical line 
    • Wages/ price flexible
    • Changes in wages/ price offset each other
    • technology, economic growth
4/1
- Phillips Curve: represents the relationship between inflation and unemployment
- Three assumptions
  1. Short run trade off between rate of inflation, and rate of unemployment (inverse)
  2. Aggregate supply shocks can cause both higher rates of inflation and higher rates of unemployment (SRPC shifts to right or outward)
  3. NO significant trade off between inflation and unemployment in the long run
*If inflation persists and expected rate or inflation rises the entire SRPC shifts upwards (Stagflation is possible)
*If inflation expectations drop due to new technology, then SRPC moves downwards
- Increase in AD = up/left movement along SRPC
- Decrease in AD = down/right movement

4/2
- Disinflation : decrease in inflation from year to year, can be seen in LRPC
- Long Run Phillips Curve

  • Represented by vertical line
  • Only shifts if the LRAS shifts
  • Because it exists at natural rate of unemployment, structural changes in economy that affect unemployment will also cause LRPC to shift
    • Increase in unemployment will shift LRPC to the right
    • Decrease in unemployment will shift LRPC to left
-Misery Index : combo of inflation and unemployment in any given year
*single digit misery is good

4/2

- Supply Shock Economics : rapid/ significant increases in resource cost, which causes SRAS curve to shift and will produce a corresponding shift in SRPC curve
        Example: Causes: Wage Hikes
- Stagflation : simultaneous increase in inflation and unemployment

4/3

- Supply Side Economics A.K.A regonomics

  • tend to believe that the AS curve will determine levels of inflation, unemployment, and economic growth
  • increase economy : AS curve would go to the right
  • Supports policies that promote GDP growth, by arguing the high marginal tax rates, along with current system of transfer payments 
  • marginal tax rate: amount of tax paid on additional dollr of income 
-Laffer Curve

  • Tax revenues from 0 to some maximum level , and then decline
  • Lower tax rates, could lead to an expansion of output and income by increasing AS and enlarging the tax base
*Three Criticisms of Laffer Curve

  • Where economy is actually located on curve is difficult to determine
  • Tax cuts also increase demand which can fuel inflation and demand may exceed supply
  • Tax rates on incentives to work save and invest are small
