HIERARCHY OF NEEDS: Developed by Abraham Maslow, the notion that people are motivated to satisfy basic physiological needs (food, shelter, etc.) before moving on to satisfying higher psychological needs (security, companionship, etc.). These alternative needs are layered in a hierarchial pattern with physiological needs on the bottom, safety needs on the second layer, belonging needs on the third layer, esteem needs on the fourth layer, and self-actualization needs at the top. This hierarchy of needs has been used to help explain the progress of human societies from agrarian to manufacturing to service to information.

MARGINAL COST The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost (MC) indicates how much total cost changes for a given change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. It is found by dividing the change in total cost (or total variable cost) by the change in output. Marginal cost is one of four cost concepts used in short-run production analysis. The other three are average total cost, average fixed cost, and average variable cost.
