THIRD-WORLD COUNTRY: A country with a relatively low standard of living and which lacks the economic development of more advanced industrialized nations like the United States. Most third-world countries are in Africa, Asia, and South America and often rise to newsworthy prominence when they have a famine, are overthrown by a military dictator, or are invaded by a more developed country. They tend to have high rates of population growth and limited success in doing what's necessary to achieve economic growth.

Elasticity and Demand
Elasticity is the relative responsiveness of one variable to changes in another variable. Economists find this notion of elasticity quite useful in the study of markets. In this lesson, we examine the basics of demand elasticity, especially the price elasticity of demand. - The first unit of this lesson, An Overview, gets us started with a review of several concepts related to elasticity and demand.
- In the second unit, The Continuum, we take a close look at how the five elasticity alternatives are reflected by demand curves.
- The third unit, Measurement, runs through some numbers for measuring the price elasticity of demand, and how elasticity values related to a straightline demand curve.
- The fourth unit, Determinants, examines how the three determinants of elasticity affect the elasticity coefficient.
- The fifth unit and final unit, Other, closes this lesson by introducing examine three related elasticity measures.

MARKET CONTROL The ability of buyers or sellers to exert influence over the price or quantity of a good, service, or commodity exchanged in a market. Market control largely depends on the number of competitors on each side of the market. If a market has relatively few buyers, but many sellers, then limited competition on the demand-side of the market means buyers tend to have relatively more market control than sellers. The converse occurs if a market has many buyers, but relatively few sellers. This is also termed market power.
