BETTER BUSINESS BUREAU: A group of businesses and organizations in a local community that seek to eliminate unethical business practices and protect consumers. The first Better Business Bureau was established in 1912 in Minnesota. Today, most local communities (read this as cities) throughout North America have Better Business Bureaus. This private response to questionable business practices should be compare with the government response, the Federal Trade Commission.

    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.

    MARGINAL FACTOR COST CURVE, MONOPSONY

    A curve that graphically represents the relation between marginal factor cost incurred by a monopsony for hiring an input and the quantity of input employed. A profit-maximizing monopsony hires the quantity of input found at the intersection of the marginal factor cost curve and marginal revenue product curve. The marginal factor cost curve for a monopsony with market control is positively sloped and lies above the average factor cost curve.
