JUST IN TIME: A method of production in which inputs used in the production process are delivered to a firm or factory immediately before they are needed. Just in time limits the inventories of raw materials and intermediate goods kept on site. While this is credited with improving microeconomic production efficiency, it might also prevent macroeconomic business-cycle instability that is attributable to the unplanned build-up of business inventories.

    Market Structures

    Our investigation into market structures lays the foundation for a closer examination of monopoly, monopolistic competition, and oligopoly. This lesson takes a look at how markets are structured based on their competitiveness, the degree of market control held by firms, the acquisition of this market control, and the use market control.

    • The first unit of this lesson, Competition And Control, begins this lesson with a look at competition and market control.
    • In the second unit, Four Types, we examine the four basic types of market structures -- perfect competition, monopoly, monopolistic competition, and oligopoly.
    • The third unit, Getting Control, then looks at two key ways that firms are able to acquire or increase their market control -- product differentiation and entry barriers.
    • In the fourth unit, Using Control, we investigate what firms do when they have market control.
    • The fifth and final unit, Government, then closes this lesson by considering the role government plays in regulating market control.
