IMMIGRATION: Migration that enters one country from another country. Immigration is usually seen as a problem for existing citizens of nation because--(1) the supply of labor increases, which tends to lower wages, (2) there's a greater demand for public services, which causes taxes to rise, and (3) the culture of immigrants is usually different, which creates all sorts of social conflicts. However, immigration can also be beneficial because--(1) the additional labor is a source of economic growth, (2) the immigrants might be willing to do some jobs that wouldn't be performed otherwise, and (3) some goods can produced at lower cost.

    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.

Limited resources are one half of the fundamental problem of scarcity that has plagued humanity since the beginning of time. The other half of the scarcity problem is unlimited wants and needs.
