How do you derive a firm's short run supply curve from their cost curves?
Question:
How do you derive a firm's short run supply curve from their cost curves?
Short-run production
Short-run refers to the period of time in which some inputs are fixed and some are variable. In the short run, there is less flexibility in production due to the presence of these fixed inputs which require heavy investment and time to adjust e.g. machinery.
