HOARDING: The act of accumulating assets, especially goods or money, over and above that needed for immediate use based on the fear or expectation of future shortages and higher prices. For example, concerns about a worldwide shortage of sugar and chocolate might prompt a consumer to purchase several hundred boxes of candy, which are stored in a wine cellar. Alternatively, someone fearing a global collapse of the financial system might be inclined to pack pillow cases with bundles of cash or stockpile gold bullion in the closet. Such hoarding, if widely practiced, can actually contribute to the anticipated shortage and higher prices.

    Market

    In this lesson, we'll see how buyers (discussed in the demand lesson) come together with sellers (discussed in the supply lesson) to exchange commodities using a market. More precisely, this lesson develops an abstract market model, or market analysis, that we can use to explain and understand a wide range of real world exchanges.

    • This lesson begins with an overview of the basic exchange process underlying markets, including the notion of equilibrium, the roles played by price and quantity, and the importance of competition.
    • In the second unit we work through a simple market analysis using demand and supply schedules, highlight both equilibrium and disequilibrium conditions.
    • The third unit then carefully examines the notion of market equilibrium using demand and supply curves, which generates the widely used graphical model of the market.
    • Moving onto the fourth unit, we use the graphical market model to investigate the automatic market responses to shortages and surpluses.
    • The lesson concludes in the fifth unit by considering the relation between market exchanges and efficiency.

    LAW OF SUPPLY

    The direct relationship between supply price and the quantity supplied, assuming ceteris paribus factors are held constant. This economic principle indicates that an increase in the price of a commodity results in an increase in the quantity of the commodity that sellers are willing and able to sell in a given period of time, if other factors are held constant. The law of supply is an important principle in the study of economics.
