Need to know

What you need to know

• Short Run: At least one factor of production is fixed.
• Fixed Costs (FC): Costs that do not vary with output (e.g., rent, insurance).
• Variable Costs (VC): Costs that vary directly with output (e.g., raw materials, wages for production staff).
• Total Cost (TC) = Total Fixed Costs (TFC) + Total Variable Costs (TVC).
• The Law of Diminishing Marginal Returns explains the shape of short-run cost curves.
