MARKET STRUCTURE: The manner in which a market is organized, based largely on the number of firms in the industry. The four basic market structure models are: perfect competition, monopoly, monopolistic competition, and oligopoly. The primary difference between each is the number of firms on the supply side of a market. Both perfect competition and monopolistic competition have a large number of relatively small firms selling output. Oligopoly has a small number of relatively large firms. And monopoly has a single firm.

Market Shocks
Our goal in this lesson is to investigate disruptions of the market. Specifically, we want to use the market model previously developed, to examine the why and how of market shocks. What causes market shocks? How to markets react when shocked? These are just a few of the questions we want to consider. If the truth be known, markets in the real world don't remain at the same locations for very long. They move. They adjust. Prices change. Quantities change. We can understand these real world market changes, by analyzing what happens to market model when it's shocked. - The first unit of this lesson lays the foundation of analyzing market shorts with an overview of the adjustment process and the particular role played by the ceteris paribus assumption.
- In the second unit, we review the five determinants of demand and five determinants of supply, because these are the are what cause market disruptions.
- We then move into the actual adjustment process in the third unit, examining the four basic disruptions involving a shift in either the demand or supply curve.
- The fourth unit builds on these four basic shifts to exam four complex shifts that have simultaneous shifts in both the demand and supply curves.
- We end this lesson in the fifth unit by relating these market shocks to the fundamental notion of cause and effect inherent in the study of economic science.

GROSS DOMESTIC PRODUCT, EXPENDITURES A method of estimating gross domestic product (GDP) based on identifying the aggregate expenditures (consumption expenditures, investment expenditures, government purchases, and net exports) made by the four macroeconomic sectors (household, business, government, and foreign). This is one of two methods used by the Bureau of Economic Analysis in the National Income and Product Accounts to estimate gross domestic product. The other identifies the value of total production from the income received by the resource owners.
