Aggregate Demand--Schedule/Curve showing the real output that buyers collectively desire to purchase at each possible price level
     --When price level increases, demand decreases
          (
substitution effect- where more of a specific product is purchased b/c it becomes cheaper relative to all other products)
     --
There is no overall substitution effect among domestically produced goods when the price level falls

Aggregate Demand Curve Downsloping
     *
Real Balances Effect--when price level falls, the purchasing power of existing financial balances (savings accts, bonds) rises.  A higher price level diminishes the value of financial balances.
     *
Interest Rate Effect-- higher demand for money means higher interest rates.  A decline in price level means lower interest rates which can increase levels of only certain types of spending.
     *
Foreign Purchases Effect-- when U.S. price level rises relative to foreign price levels, foreigners buy fewer U.S. goods (=fewer exports) & Americans buy more foreign goods (=more imports).

Determinants of Aggregate Demand

     1. Consumer Spending   <--less,  more-->
          a. Consumer Wealth, change in real value of
          b. Consumer Expectations about the future
          c. Household Indebtedness
          d. Taxes
     2. Investment Spending- purchasing capital goods. <--decline, increase-->
          a. Real Interest Rate- from a change in the nation's $ supply.
          b. Expected Returns due to:
               --expectations about future business conditions
               --technology- new & improved (ex: internet, railroad)
               --degree of excess capacity-(too much inventory, useless employees)
               --business taxes (will reduce profit, just like personal taxes)
     3. Government Spending- the more $ govt puts into econ, the more beneficial
     4. Net Export Spending- (higher exports = higher demand for U.S. goods)
          --National Income Abroad- if foreign income rises, they buy more US goods
          --Exchange rates may effect US net exports, and therefore AD
