Hi everyone, in this video I discuss deriving out long run marginal cost curve. In order to understand the derivation of our long run marginal cost curve, we need to understand the derivation of our long run average cost curve as the lower envelope of the firms short run average cost curves, although I go through a quick review here, you might want to look at my more in depth video on finding the Long Run Average Cost Curve here: [ Ссылка ]

If you are already comfortable with deriving the long run average cost curve, you can just skip straight to the second part of the video.
