PERFECT COMPETITION, REVENUE DIVISION: The marginal approach to analyzing a perfectly competitive firm's short-run profit maximizing production decision can be used to identify the division of total revenue among variable cost, fixed cost, and economic profit. The U-shaped cost curves used in this analysis provide all of the information needed on the cost side of the firm's decision. The demand curve facing the firm (which is also the firm's average revenue and marginal revenue curves) provides all of the information needed on the revenue side.

    Production

    • The first unit of this lesson, Short-Run Production, begins our study by introducing a few basic concepts underlying production, especially short run, long run, fixed input, and variable input.
    • In the second unit, Production Measures, we take a look the three standard measures of production -- total product, average product, and marginal product.
    • The third unit, Product Curves, then presents graphical relations for these three measures -- total product curve, average product curve, and marginal product curve.
    • In the fourth unit, Long-Run Production, we examine the role returns to scale play in long-run production.
    • The fifth and final unit, Supply, then closes this lesson by previewing the importance of production to the supply decisions by firms.s

    INFLATION PROBLEMS

    Two notable problems are associated with inflation--uncertainty and haphazard redistribution. Inflation, especially inflation that varies from month to month and year to year, makes long-term planning quite difficult. Prices, wages, taxes, interest rates, and other nominal values that enter into consumer, business, and government planning decisions can be significantly affected by inflation. Moreover, inflation tends to redistribute income and wealth in a haphazard manner--some people win and some people lose. This redistribution might not be that desired by society, failing to promote any of the basic economic goals of efficiency, equity, stability, growth, or full-employment.

    [What's This?]

    Today, you are likely to spend a great deal of time watching infomercials wanting to buy either a combination CD player, clock radio, and telephone (with answering machine) or a revolving spice rack. Be on the lookout for spoiled cheese hiding under your bed hatching conspiracies against humanity.

    This isn't me! What am I?

    In his older years, Andrew Carnegie seldom carried money because he was offended by its sight and touch.
