    Gross Domestic Product

    This lesson investigates one of the most noted and important measures of macroeconomic activity -- gross domestic product (GDP). GDP measures the total production of goods and services that, in principle, are available to satisfy consumers wants and needs. We see the ins and outs of the GDP measure. As a bonus, we also get a close look at several related measures of production and income, including net domestic product (NDP), national income (NI), personal income (PI), and disposable income (PI).

    • In the first unit of this lesson, we take a look at the process of measuring gross domestic product, including what, in principle, is being measure.
    • The second unit the turns to a detailed look at what IS included in GDP and what IS NOT included in the GDP based on the difference between market transactions and economic production.
    • With the third unit we take a look at the two views of measuring GDP -- expenditures and resource costs.
    • Moving on to the fourth unit, we get a look at the three related measures of income -- national income, personal income, and disposable income.
    • And finally, the fifth unit considers a few issues related to measuring GDP, including what BDP does measure and what GDP doesn't measure.

    AVERAGE PHYSICAL PRODUCT

    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 product, which more often goes by the shorter name average product (AP), is one of two measures derived from total physical product. The other is marginal physical product.
