CAPITAL: One of the four basic categories of resources, or factors of production. It includes the manufactured (or previously produced) resources used to manufacture or produce other things. Common examples of capital are the factories, buildings, trucks, tools, machinery, and equipment used by businesses in their productive pursuits. Capital's primary role in the economy is to improve the productivity of labor as it transforms the natural resources of land into wants-and-needs-satisfying goods.

    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.

    TOTAL PRODUCT CURVE

    A curve that graphically represents the relation between total production by a firm in the short run and the quantity of a variable input added to a fixed input. When constructing this curve, it is assumed that total product changes from changes in the quantity of a variable input (like labor), while other inputs (like capital) are fixed. This is one of three key product curves used in the analysis of short-run production. The other two are marginal product curve and average product curve.

    Today, you are likely to spend a great deal of time at a garage sale wanting to buy either a large stuffed brown and white teddy bear or a replacement washer for your kitchen faucet. Be on the lookout for empty parking spaces that appear to be near the entrance to a store.

    Okun's Law posits that the unemployment rate increases by 1% for every 2% gap between real GDP and full-employment real GDP.
    "He, who every morning plans the transactions of the day, and follows that plan, carries a thread that will guide him through a labyrinth of the most busy life."
