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.

INCOME-EXPENDITURE MODEL: A macroeconomic model, which captures the essence of Keynesian economics, is based on the equality between total income generated from gross domestic product and total expenditures on gross domestic product. The cornerstone of the income-expenditure model is the consumption function, which relates household consumption expenditures to income and gives rise to the aggregate expenditure line with the addition of investment, government purchases, and net exports. The intersection between the aggregate expenditure line at the 45-degree identifies equilibrium.
