WEALTH: The net ownership of material possessions and productive resources. In other words, the difference between physical and financial assets that you own and the liabilities that you owe. Wealth includes all of the tangible consumer stuff that you possess, like cars, houses, clothes, jewelry, etc.; any financial assets, like stocks, bonds, bank accounts, that you lay claim to; and your ownership of resources, including labor, capital, and natural resources. Of course, you must deduct any debts you owe.

    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.

    INFORMATION

    The transfer of knowledge from one person to another. Information is a flow concept. It requires someone (or something) to do the sending and someone to do the receiving. Information is a valuable commodity that provides benefits, but also incurs an opportunity cost to produce, meaning information is never perfect or complete. The existence of asymmetric information (some have more information than others) gives rise to the problems of adverse selection, moral hazard, and the principal-agent problem.
