ABSOLUTE POVERTY LEVEL: The amount of income a person or family needs to purchase an absolute amount of the basic necessities of life. These basic necessities are identified in terms of calories of food, BTUs of energy, square feet of living space, etc. The problem with the absolute poverty level is that there really are no absolutes when in comes to consuming goods. You can consume a given poverty level of calories eating relatively expensive steak, relatively inexpensive pasta, or garbage from a restaurant dumpster. The income needed to acquire each of these calorie "minimums" vary greatly. That's why some prefer a relative poverty level.

Marginal revenue is the slope of the total revenue curve and is one of two revenue concepts derived from total revenue. The other is average revenue. To maximize profit, a firm equates marginal revenue and marginal cost.
