SCARCITY: A pervasive condition of human existence that exists because society has unlimited wants and needs, but limited resources used for their satisfaction. In other words, while we all want a bunch of stuff, we can't have everything that we want. In slightly different words, this scarcity problem means: (1) that there's never enough resources to produce everything that everyone would like produced; (2) that some people will have to do without some of the stuff that they want or need; (3) that doing one thing, producing one good, performing one activity, forces society to give up something else; and (4) that the same resources can not be used to produce two different goods at the same time. We live in a big, bad world of scarcity. This big, bad world of scarcity is what the study of economics is all about. That's why we usually subtitle scarcity: THE ECONOMIC PROBLEM.

AUTONOMOUS EXPENDITURES Expenditures on aggregate production by the four macroeconomic sectors that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in these expenditures. Each of the four aggregate expenditures--consumption, investment expenditures, government purchases, and net exports--have an autonomous component. Autonomous expenditures are affected by the ceteris paribus aggregate expenditures determinants and are measured by the intercept term of the aggregate expenditures line. The alternative to autonomous expenditures are induced expenditures, expenditures which do depend on income.

[What's This?]
Today, you are likely to spend a great deal of time visiting every yard sale in a 30-mile radius seeking to buy either a pair of red and purple designer socks or a T-shirt commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for bottles of barbeque sauce that act TOO innocent.
