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.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
