POINT ELASTICITY: The relatively responsiveness of a change in one variable (call it B) to an infinitesimally small change in another variable (call it A). The notion of point elasticity typically comes into play when discussing the elasticity at a specific point on a curve.< P>Point elasticity can be calculated in a number of different ways. Sophisticated economists, using sophisticated mathematical techniques (better known as calculus) can calculate point elasticity by taking derivatives of equations. Derivatives is fancy calculus talk for infinitesimally small changes.

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.

BANK ASSETS What a bank owns, including loans, reserves, investment securities, and physical assets. Bank assets are typically listed on the left-hand side of a bank's balance sheet. Bank liabilities, what a bank owes, are listed on the right-hand side of a bank's balance sheet. Net worth is the difference between assets and liabilities. The largest asset category of most bank is loans, which generates interest revenue. A critical asset category used to maintain the safety of deposits is reserves (vault cash and Federal Reserve deposits).
