APP: The abbreviation of average physical product, which is the quantity of total output produced per unit of a variable input, holding all other inputs fixed. Average physical product, usually abbreviated APP, is found by dividing total physical product by the quantity of the variable input. Average physical product is actually just another name for average product (AP). But don't be confused by the extra term (physical).

  4. Net Exports: Changes in exports can trigger expansions and contractions of the domestic economy.
