INSIDER TRADING: The buying and selling of corporate stock or other financial instruments based on knowledge that is not widely available to the general public. Insider trading is most often undertaken by corporate executives or directors using information that they have acquired by working "inside" the company. Insider trading is illegal because it gives an unfair advantage to those on the inside. The president of a pharmaceutical company might be inclined to sell stock in the company using advanced information that the government is about to decline the patent application for a new drug.

    Utility and Demand

    This lesson undertakes a detailed investigation into the decision-making process underlying the purchase of goods and services. Doing so provides a behind-the-scenes examination of market demand, offering an explanation for the inverse relation between demand price and quantity demanded that is the law of demand.

    • The first unit of this lesson, The Set Up, begins with a review of the market demand and consumer demand theory.
    • In the second unit, A Simple Choice, we examine the decision-making process for purchasing a single good.
    • The third unit, Complex Choices, then complicates matters slightly by adding a second good into the decision making mix.
    • The fourth unit, On To Demand, presents the rule of consumer equilibrium that captures the essence of this decision-making process and how it helps explain the law of demand.
    • The fifth unit and final unit, Beyond Demand, explores how consumer demand theory provides insight to noneconomic choices, demand elasticity, and market supply.

    RULE OF CONSUMER EQUILIBRIUM

    A condition of consumer equilibrium and utility maximization stating that the marginal utility-price ratios for all goods are equal. This rule is a handy way of checking for consumer equilibrium and utility maximization. If the rule is not satisfied, then consumer equilibrium and utility maximization are not achieved.
