REVENUE EFFECT: The goal of imposing taxes to generate revenue used to finance the operation of government, most notably to finance the provision of public goods. This is one of two reasons, and the primary reason, that governments impose taxes. The other reason is the allocation effect. Governments work the revenue effect because they need access to income and resources to build highways, defend the nation, educate the population, and maintain the legal system. They purchase these resources with tax revenue generated through the revenue effect.

    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.

    AUTONOMOUS INVESTMENT

    Business investment expenditures that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in investment. Autonomous investment is best thought of as investment that the business sector undertakes regardless of the state of the economy. It is measured by the intercept term of the investment line. The alternative to autonomous investment is induced investment, which does depend on income.
