INJECTIONS-LEAKAGES MODEL: A model used in Keynesian economics based on the equality of non-consumption expenditures (or injections) and non-consumption uses of income (leakages). On one side of the equality is saving, taxes, and imports -- the non-consumption leakages. On the other side of the equality is investment, government purchases, and exports -- the non-consumption injections. The injection-leakage model provides an alternative to the Keynesian cross for identifying equilibrium aggregate output.

Supply
This supply lesson provides an introduction into selling a wide range of goods. In fact, this supply topic does more than offer insight into selling behavior. It's also the second half of the market analysis -- the first half being demand. And to reiterate what I noted during the demand lesson, market analysis is one of the most widely used tools in the study of economics that can be used to explain a lot of economic phenomenon. Of course to use markets, we need both demand and supply. And supply part is our current lesson. - The first unit of this lesson introduces the basic concept of supply and a few related terms such as supply price and quantity supplied.
- In the second unit then we move into a discussion of the law of supply, which captures the basic relation between supply price and quantity supplied.
- The third unit then develops the supply curve, which is the graphical embodiment of the supply concept.
- Moving onto the fourth unit, we examine how the five basic supply determinants cause the supply curve to shift from one location to another.
- And in the fifth and final unit, we make a connection between supply and the limited resources part of scarcity.

MARGINAL REVENUE CURVE A curve that graphically represents the relation between the marginal revenue received by a firm for selling its output and the quantity of output sold. A firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve. The marginal revenue curve for a firm with no market control is horizontal. The marginal revenue curve for a firm with market control is negatively sloped and lies below the average revenue curve.
