Production Possibilities
In this lesson we'll take a trip through production possibilities. Production possibilities is a handy little analysis that lets us consider what the economy is capable of doing, production-wise. We'll see how a production possibilities curve, the cornerstone of this analysis, is derived and how it can be used to understand several important concepts, including opportunity cost, unemployment, investment, and economic growth. - The first unit, Getting Started, begins this lesson by laying the foundations for production possibilities analysis, especially assumptions and limitations.
- We turn out attention in the second unit, The Schedule, to the production possibilities schedule, a simple table that gives us a first shot on this analysis.
- The production possibilities curve is then derived from the production possibilities schedule in the third unit, The Curve, with particular emphasis on the importance of opportunity cost
- In the fourth unit, Analysis, we make use of the production possibilities analysis for an understanding of three important concepts: full employment, unemployment, and economic growth.
- And lastly, the fifth unit, Investment, uses production possibilities to analyze investment in capital goods as a means of achieving economic growth.

MARGINAL UTILITY OF INCOME The change in utility resulting from a given change in income. This is a specialized case of the general notion of marginal utility, which is simply the change in utility resulting from a given change in the consumption of a good. Marginal utility of income is key to identifying alternative risk preferences, including risk aversion, risk neutrality, and risk loving. These three risk preferences are indicated by three marginal utility of income possibilities, decreasing (risk aversion), increasing (risk loving), and constant (risk neutrality).
