The value of the marginal product of a factor determines its earnings. Learn about activity based approaches, many using food, to teach opportunity cost, cost-benefit analysis, and comparative advantage. When a manufacturer wishes to expand its operations, either by adding new product lines or increasing the volume of goods produced from the current product line, a marginal analysis of the costs and benefits is necessary. On average, it costs $5 to produce a single widget, but because of the new machinery, producing the 101st widget only costs $1.

Marginal analysis is an examination of the additional benefits of an activity compared to the additional costs incurred by that same activity. For example, if the cost of making 9 pieces of pizza is $90 and the cost of making 10 pieces is $110, the marginal cost of producing the tenth piece of pizza is $20.
