LRAC CURVE: The common abbreviation for the long-run average cost curve, which is a curve depicting the per unit cost of producing a good or service in the long run when all inputs are variable. The long-run average cost curve can be derived in two ways. On is to plot long-run average cost, which is, long-run total cost divided by the quantity of output produced. at different output levels. The more common method, however, is as an envelope of an infinite number of short-run average total cost curves. Such an envelope is base on identifying the point on each short-run average total cost curve that provides the lowest possible average cost for each quantity of output. The long-run average cost curve is U-shaped, reflecting economies of scale (or increasing returns to scale) when negatively-sloped and diseconomies of scale (or decreasing returns to scale) when positively sloped. The minimum point (or range) on the LRAC curve is the minimum efficient scale.

    Elasticity and Demand

    Elasticity is the relative responsiveness of one variable to changes in another variable. Economists find this notion of elasticity quite useful in the study of markets. In this lesson, we examine the basics of demand elasticity, especially the price elasticity of demand.

    • The first unit of this lesson, An Overview, gets us started with a review of several concepts related to elasticity and demand.
    • In the second unit, The Continuum, we take a close look at how the five elasticity alternatives are reflected by demand curves.
    • The third unit, Measurement, runs through some numbers for measuring the price elasticity of demand, and how elasticity values related to a straightline demand curve.
    • The fourth unit, Determinants, examines how the three determinants of elasticity affect the elasticity coefficient.
    • The fifth unit and final unit, Other, closes this lesson by introducing examine three related elasticity measures.

    AVERAGE FACTOR COST CURVE, MONOPSONY

    A curve that graphically represents the relation between average factor cost incurred by a firm for employing an input and the quantity of input used. Because average factor cost is essentially the price of the input, the average factor cost curve is also the supply curve for the input. The average factor cost curve for a firm with no market control is horizontal. The average factor cost curve for a firm with market control is positively sloped.
