USER CHARGE: A tax that's disguised as a pricea charge for the use of a publicly provided good. Government produces and supplies a number of nearpublic goods, like education, libraries, parks, and transportation systems. The "prices" for these goods are user charges. The logic is that people who benefit from the good and are willing to pay, should pay for them. While this helps pay production costs, it tends to be inefficient.

MARGINAL ANALYSIS: A basic technique used in economics that analyzes small, incremental changes in key variables. Marginal analysis is the primary analytical approached used in the study of markets, production, consumption, business cycles, and economic policies. It not only reflects how most economic decisions are made, it also lends itself to mathematical and graphical analysis. Marginal analysis is based on a simple question often posed in the study of economics: "What happens if something changes by one dollar, one unit, one person, or one whatever?" For example, what happens to the quantity demanded of hot fudge sundaes if the market price',500,400)">market price increases by one cent? Or what happens to gross domestic product if investment decreases by $1? Or what happens to the market price of computers if one more computer supplier enters the industry?Marginal ObsessionThe apparent economic obsession with marginal changes exists for at two notable reasons. Incremental Decisions: One reason is that many economic decisions made in the real world are made "at the margin." Duncan Thurly decides whether or not to eat one more slice of pizza at the allyoucaneat pizza lunch buffet after having eaten five slices. Winston Smythe Kennsington III decides whether or not to hire an additional worker to the current staff. The Shady Valley City Council debates over adding an extra penny to their existing sales tax. These are marginal decisions, one and all, and just the sort of phenomena investigated with marginal analysis.
 Sophisticated Analysis: A second reason for using marginal analysis can best be termed analytical sophistication. Economists frequently make use of highpowered mathematical techniques, especially calculus, to create models of markets, consumer behavior, production decisions, or the aggregate economy. Such highpowered mathematical techniques not only lend themselves easily to analyzing incremental changes, but also to building extremely complex models that use these incremental changes to reveal interactions, implications, and conclusions about the economy that are often far from obvious. For example, such a complex model might reveal how a financial crises in Asia affects the construction of new homes in California.
Marginal SlopeSlope and Marginal 

 The use of marginal analysis works nicely with both mathematical and graphical analysis. Marginal means incremental change. In simple mathematical terms the slope parameter of an equation captures the marginal change. In a graph, the slope of a line captures a marginal change. In effect, the term "marginal" is synonymous with the term "slope."Consider this simple equation that captures a linear relation between two variables X and Y: Y = a + bX The key point of focus is the slope parameter, b. This equation indicates that each 1 unit change in X results in a change in Y by the value of b. If b is 4, then an increase in X by 1 results in Y increasing by 4. The slope parameter b captures the marginal change in Y resulting from a change in X.Now consider a simple graph of a line such as Y = a + bX. It too captures marginal change as the slope. This exhibit displays a positivelysloped line. The numerical value of the slope of the line is 4. This value captures the marginal change in Y measured on the vertical axis resulting from a change in X measured on the horizontal axis. An increase in X by 1 results in Y increasing by 4.
