@nbayounga Technically, SRAC is higher than or equal to LRAC. But, that only happens when the firm is stuck with the "right" amount of capital (what it would choose in the long run) in the short run.
@intromediateecon If there is an increase in demand for iron ore (example) then firms will have to increase their production level right? how will this be shown using a diagram? will it be a shift of the isoquant curve to the right?
@MegaRazorex The cost curves will shift upward from their current position (in the same way as each other). Earlier in this series of videos, I explain why AVC = w/(average product). If w goes up, AVC goes up too (and in a parallel fashion).
