KEYNESIAN AGGREGATE EXPENDITURE MODEL: The generic term for several graphical models used to analysis the basic components of Keynesian economics and to identify Keynesian equilibrium as the intersection of the aggregate expenditures line and the 45-degree line. Differences among the specific models are based on which sectors are included (household, business, government, and foreign) and whether expenditures are induced or autonomous.

Page: 2 of 17

We live in a big, bad world of scarcity. Meaning: - There's never enough resources to produce everything that everyone wants,
- Some people have to do without some of the stuff that they want or need,
- The same resources can not be used to produce two different goods at the same time, and
- Doing one thing, producing one good, performing one activity, forces you to give up something else.
Then: - Scarcity is what the study of economics is all about.

Government failures are based on the utility-maximizing behavior of politicians, voters, nonvoters, special interest groups, and government employees. The identification and analysis of government failures is central to the study of public choice and offers something of a counterbalance to government actions designed to address the inefficiencies of market failures.
