ELASTICITY AND SUPPLY INTERCEPT: The intersection of a straight-line supply curve with vertical price axis and/or horizontal quantity axis reveals the relative price elasticity of supply. Intersection with the horizontal quantity axis means inelastic and intersection with the vertical price axis means elastic. Intersection with the origin means unit elastic supply.

Economic Basics
Being the very first lesson in this course, this provides an introduction and overview of economics. You'll come across a lot of basic concepts and terms. The full importance of these may not become apparent until later lessons, but they will be important. The five units making up this lesson set the stage for the further study of economics. - The first unit offers up a basic definition and provides two useful lists -- the three questions of allocation and the seven rules of economics.
- The second unit then explores the practice of economics, including positive and normative economics, macroeconomics and microeconomics, and six common logical fallacies.
- In the third unit, we turn our attention to the economy, especially how real world economies contain a mix of markets and governments.
- We then examine the five basic goals of a mixed economy in the fourth unit, include the three macro goals of full employment, stability, and growth; and the two micro goals of efficiency and equity.
- The fifth and final unit in this lesson considers assorted economic policies that governments use to achieve the five economic goals.

MARGINAL COST AND LAW OF DIMINISHING MARGINAL RETURNS Decreasing then increasing marginal cost, reflected by a U-shaped marginal cost curve, is the result of increasing then decreasing marginal returns. In particular the decreasing marginal returns is caused by the law of diminishing marginal returns. As such, the law of diminishing marginal returns affects not only the short-run production of a firm but also the cost of short-run production. This translates into a positively-sloped supply curve for profit-maximizing competitive firms.
