MARGINAL-COST PRICING: A pricing scheme in which the price received by a firm is set equal to the marginal cost of production. This is not only the efficient outcome achieved by competitive markets, it is commonly used for comparison of other regulatory policies, such as average-cost pricing, that are used for public utilities (especially those that are natural monopolies). The bad thing about marginal-cost pricing for natural monopolies is that a normal profit is not guaranteed. The good thing about marginal-cost pricing is that marginal cost is equal to price, and the public utility is operating according to the price equals marginal cost (P = MC) rule of efficiency.

    Economic Basics

    This lesson provides an introduction and overview of economics. You'll come across a number of basic concepts and terms. The full importance of these might not be apparent until later lessons, but they WILL be important. Like other lessons to come, this one is divided into five units.

    • The first unit, Economics, offers up a definition of economics and provides two useful lists -- the three questions of allocation and the seven rules of economics.
    • The second unit, Doing Economics, explores the practice of economics, including positive and normative economics, macroeconomics and microeconomics, and six common logical fallacies.
    • In the third unit, An Economy, we turn our attention to real world economies that contain a mix of markets and governments.
    • We then examine the five basic goals of a mixed economy in the fourth unit, Economic Goals, including 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, Economic Policies, considers assorted economic policies that governments use to achieve the five economic goals.

    INDUCED INVESTMENT

    Business investment expenditures that depend on income or production (especially national income and gross domestic product). That is, changes in income induce changes in investment. Induced investment reflects the observation that the business sector is inclined to reinvest profits (boosted by a growing economy) in capital goods. It is measured by the marginal propensity to invest (MPI) and is reflected by the positive slope of investment line. The alternative to induced investment is autonomous investment, which does not depend on income.
