Microeconomics | Cost | Chapter 6 | Part 3


Summary

This video provides a comprehensive explanation of marginal cost, defining it as the extra cost incurred when producing one more unit. It delves into the calculation of marginal cost using the formula of change in total cost divided by change in quantity. The video explores how marginal cost is influenced by variable cost, while remaining unaffected by fixed cost, and examines its relationships with average cost, average variable cost, and total cost. Additionally, it discusses the interplay between marginal cost and average cost, as well as the connection between marginal cost and total cost.
