ACCELERATOR: The ratio between investment expenditures and the change in gross domestic product. This is based on the notion that business investment depends on the rate of growth of aggregate output. If the economy is expanding, in other words, then the business sector invests in more capital goods to produce the extra output needed. This accelerator effect modifies and magnifies the simply multiplier effect based on the induced consumption and the marginal propensity to consume.

Scarcity
In this lesson you'll see why scarcity tends to make economists grumpy. You'll see that scarcity is a perpetual condition that exists because people have unlimited wants and needs, but limited resources used to satisfy these wants and needs. You'll also see how this scarcity problem underlies the common notion of cost, which is integral to the study of economics. The five units contained in this lesson provide a tour through the economic problem of scarcity. - The first unit examines the fundamental concept of scarcity -- the combination of limited resources and unlimited wants and needs -- that is virtually synonymous with the study of economics.
- The second unit discusses the four basic categories of limited resources --labor, capital, land, and entrepreneurship -- that produce the goods that are used to satisfy unlimited wants and needs.
- In the third unit, we take a look at the notion of opportunity cost and see how it is related to the scarcity problem.
- We then turn out attention in the fourth unit to a simple example of the explicit and implicit costs of attending college.
- The fifth and final unit in this lesson then ponders why scarcity is considered THE economic problem and providing a little insight into why economists are grump.

AGGREGATE DEMAND The total real expenditures on final goods and services produced in the domestic economy that buyers are willing and able to undertake at different price levels, during a given time period (usually a year). Aggregate demand, usually abbreviated AD, is an inverse relation between price level and aggregate expenditures. This is one half of the AS-AD (aggregate market) analysis. The other half is aggregate supply. Aggregate demand consists of four aggregate expenditures--consumption expenditures, investment expenditures, government purchases, and net exports--made by the four macroeconomic sectors--household, business, government, and foreign.
