INDIFFERENCE CURVE: A curve that graphically depicts various combinations of goods that generate the same level of utility to a consumer. In other words, a consumer is "indifferent" among any of the bundles because they all provide the same satisfaction. Indifference curves are combined with a budget line or constraint for indifference curve analysis used to explain many aspects of demand, including the slope of the demand curve and the income and substitution effects.

    Money

    In this lesson, we examine my favorite economic topic -- money. In addition to being the root of all evil, money is a critical component of the macroeconomy. The basic rule is that too much money causes inflation and too little money causes unemployment. To lay the foundation for further study of money and the macroeconomy, this lesson presents the money basics, including what money is, what money does, how money is measured, and how money evolved to it's current format.

    • The first unit begins this lesson with a look at what money is (hint: anything that people use for exchanges), and money's role as a medium of exchange.
    • The main topics of the second unit are the four functions of money and the four characteristics of money.
    • The third unit then examines and compares the monetary aggregates, the official measures of money tracked by the U.S. government.
    • The history of money is the prime topic of the fourth unit, with a look at how modern fiat money evolved from self sufficiency, barter, and commodity money.
    • The fifth unit then ponders the connection between money, efficiency, and the scarcity problem, with an eye toward the use of monetary policies.

    PERFECT COMPETITION, EFFICIENCY

    Perfect competition is an idealized market structure that achieves an efficient allocation of resources. This efficiency is achieved because the profit-maximizing quantity of output produced by a perfectly competitive firm results in the equality between price and marginal cost. In the short run, this involves the equality between price and short-run marginal cost. In the long run, this is seen with the equality between price and long-run marginal cost at the minimum efficient scale of production.
