 LEAKAGE LINE: A line used in the injection-leakage model representing the relation between non-consumption uses of income (that is, leakages) and national income. The three leakages are saving, taxes, and imports. The foundation of the leakages line is the saving line, which is then enhanced by adding taxes and imports. The other part of the injection-leakage model is a line representing injections. The intersection of the injection and leakage lines identifies equilibrium aggregate output, or Keynesian equilibrium.

GRAPHICAL ANALYSIS:

The process of investigating phenomena, especially economic phenomena, in a systematic manner using diagrams and graphs. Graphical analysis is commonly used to display abstract scientific relations, then to manipulate those relations to gain greater understanding of real world events. The market model is a primary example of graphical analysis.
Graphs are two-dimensional pictures used to represent economic relations between two (or more) variables. Graphical analysis is most interesting and useful when it combines two or more relations into a single diagram. The interaction among these relations is then analyzed for insight into the workings of the economic world.

### A Primer On Graphs

Consider three common types of graphs:
• Pie Chart: A graph commonly used to present the division of a total among parts is a pie chart. Click the [Pie Chart] button to illustrate. This particular pie chart represents the division of national income among different factor payments--wages, interest, rent, and profit. The pie is the total and each slice represents the portion distributed to each category. Pie charts are a handy way to present information, but are not well suited for more involved economic analysis.

• Bar Chart: A graph used to present data for discrete categories is a bar chart. Click the [Bar Chart] button to illustrate. This bar chart indicates the unemployment rate for each of five demographic groups--total population, males, females, whites, and non-whites. A bar chart provides a useful way to compare information about different groups or categories.

• Line Graph: A graph that tends to be most useful in the construction of graphical models and in doing economic analysis is a line graph. Click the [Line Graph] button to illustrate. This particular line graph shows the relation between two variables--price and quantity. Such line graphs are ideally suited for illustrating scientific principles and hypotheses. They can be used to show how one variable (quantity) is affected by changes in another variable (price).

### Two Relations

Two alternative relations are commonly illustrated with line graphs.
• Positive or Direct: One type of line graph illustrated by clicking the [Positive Relation] button represents a positive or direct relation between two variables, such as price and quantity. With this line, a higher price is related to a larger quantity. Another way of stating this is that the slope of the line is positive. A common positive relation in economics is the market supply curve.

• Negative or Indirect: A second type of line, one that represents a negative or indirect relation between two variables, such as price and quantity, can be seen by clicking the [Negative Relation] button. With this line, a lower price is related to a larger quantity. Another way of stating this is that the slope of the line is negative. A common negative relation in economics is the market demand curve.
