X: The standard abbreviation for exports produced by the foreign sector and purchased by the domestic economy, especially when used in the study of macroeconomics. This abbreviation is most often seen in the aggregate expenditure equation, AE = C + I + G + (X - M), where C, I, G, and (X - M) represent expenditures by the four macroeconomic sectors, household, business, government, and foreign. The United States, for example, sells a lot of the stuff produced within our boundaries to other countries, including wheat, beef, cars, furniture, and, well, almost every variety of product you care to name.

Lesson 3: Scarcity | Unit 1: The Concept
|
Page: 1 of 17
|
- Scarcity is the pervasive condition that exists because society has unlimited wants and needs, but limited resources used for their satisfaction.
Meaning:- We can't have everything because resources are limited.
Unlimited wants and needs are half of the scarcity problem.- Unlimited wants and needs are what motivate us to take action, to produce goods, and to advance our well-being.
- We are motivated to do things that satisfy these wants and needs. Satisfaction is achieved when wants and needs are fulfilled.
- Scarcity results because wants and needs are unlimited. No one has ever been completely satisfied. We always want more.
Limited resources are the other half of our scarcity problem. - Resources are the stuff that we use to produce the goods that fulfill our wants and needs.
- Resources are the things that make satisfaction possible.
- Resources are limited. We have only so much 'stuff' than can be used to produce the goods that satisfy our wants and needs.

FEDERAL DEFICIT, AGGREGATE DEMAND DETERMINANT One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in the federal deficit causes an increase (rightward shift) of the aggregate curve. A decrease in the federal deficit causes a decrease (leftward shift) of the aggregate curve. Other notable aggregate demand determinants are interest rates, inflationary expectations, and the money supply.

[What's This?]
Today, you are likely to spend a great deal of time at a going out of business sale looking to buy either a T-shirt commemorating yesterday or a pair of handcrafted oven mitts. Be on the lookout for small children selling products door-to-door.
