Define Marginal Cost or MC

Question

Define Marginal Cost and also its functions?

Answer 1

Marginal Cost (MC): It is the additional cost of producing an extra unit of similar product. In this module, marginal cost drops/falls and then increases as the level of production rises. The cause for this pattern in marginal cost is that the firm experiences rising returns to production initially (that is, higher further output per each additional unit of input), however as production carries on to grow, diminishing returns to production take place (that is, lower additional output per each additional unit of input). Diminishing returns take place in short run due to utilization of variable resources in grouping with at least one fixed factor of the production.
