REAL PURCHASING POWER: The ability to acquire wants-and-needs satisfying goods and services with income or money. The real purchasing power of income or money depends on the prices of the goods and services. If the price level, for example, doubles, then a given amount of money can purchase half as many goods and services.

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.

RESOURCE QUANTITY, AGGREGATE SUPPLY DETERMINANT One of three categories of aggregate supply determinants assumed constant when the short-run and long-run aggregate supply curves are constructed, and which shifts both aggregate supply curves when it changes. An increase in a resource quantity causes an increase (rightward shift) of both aggregate supply curves. A decrease in a resource quantity causes a decrease (leftward shift) of both aggregate supply curves. The other two categories of aggregate supply determinants are resource quality and resource price. Specific determinants falling into this general category include population, labor force participation, capital stock, and exploration. Anything affecting the quantity of labor, capital, land, and entrepreneurship is also included.
