UNLIMITED WANTS AND NEEDS: A characteristic of people such that they are never totally satisfied with the quantity and variety of goods and services. This is one half of the fundamental problem of scarcity that has plagued humanity since the beginning of time. The other half of the scarcity problem is limited resources. Unlimited wants and needs essentially means that people never get "enough"--that there's always something else that they would want or need.

    Aggregate Demand

    This lesson introduces aggregate demand, the demand-side of the aggregate market. The aggregate market is the key model used to explain and analyze the workings of the macroeconomy and aggregate demand is a critical half of this model (the other is aggregate supply). Taking a clue from market demand, this lesson examines the nature of aggregate demand, including the relation between the price level and aggregate expenditures, the reason the aggregate demand curve is negatively sloped, and the assorted aggregate demand determinants that cause the aggregate demand curve to shift.

    • The first unit of this lesson introduces the concept of aggregate demand and how it fits into the study of macroeconomics in terms of the aggregate market and circular flow.
    • In the second unit, we example the four aggregate expenditures -- consumption, investment, government purchases, and net exports -- the make up aggregate demand.
    • The third unit then examines the aggregate demand curve that captures the aggregate demand relation between the price level and aggregate expenditures, especially the importance of the real-balance, interest-rate, and net-export effects.
    • A look at the assorted aggregate demand determinants that shift the aggregate demand curves is the topic of the fourth lesson.
    • We end this lesson in the fifth unit with a look how demand-management policies work to stabilize business cycles through aggregate demand.
