ANTITRUST: The generally process of preventing monopoly practices or breaking up monopolies that restrict competition. The term antitrust derives from the common use of the trust organizational structure in the late 1800s and early 1900s to monopolize markets. The most noted example of the use of a monopoly trust was the Standard Oil Trust, controlled by J. D. Rockefeller and dismantled through the Sherman Act in 1911. The creation of similar monopoly trusts led to the several antitrust laws, including the Sherman Act, the Clayton Act, and the Federal Trade Commission Act.

    Elasticity Basics

    In this lesson, we will examine the basics of elasticity, including what it is, how it is measured, and how it is used in market analysis.

    • The first unit of this lesson, The Concept, introduces the elasticity concept and previews its role in market analysis.
    • In the second unit, A Little More, examines the importance of elasticity for such topics as market shocks, taxes, and price controls.
    • The third unit, Measurement, takes a close look at how elasticity is measured, focusing on the coefficient of elasticity.
    • The fourth unit, A Continuum, examines the five categories of elasticity, ranging from elastic to inelastic, that form a continuum.
    • The fifth unit and final unit, Market Elasticity, closes this lesson by introducing four key elasticity concepts for the market demand and supply.

    SELLERS' MARKET

    A disequilibrium condition in a competitive market that has a shortage or excess demand. Because the quantity demanded is greater than the quantity supplied, sellers have the "upper hand" when negotiating. A sellers' market also goes by the more common term of shortage. The alternative to a sellers' market is a buyers' market, which has a surplus or excess supply.
