Cost Concepts and Farm Planning
What the domain covers
This domain tests fixed and variable costs, explicit and implicit costs, short-run cost curves and the CACP cost concepts used in Indian cost of cultivation studies. It also tests farm planning through budgeting.
Core rules and concepts
- Fixed costs do not vary with output in the short run; variable costs do.
- Explicit costs are paid out; implicit costs are imputed, such as family labour and owned land.
- Cost A1: paid-out costs. A2: A1 plus rent paid for leased-in land. B1: A2 plus interest on owned fixed capital. B2: B1 plus rental value of owned land. C1: B1 plus family labour. C2: B2 plus family labour. C3: C2 plus 10% of C2 for management.
Worked example
Hired labour ₹20,000; seed ₹5,000; fertiliser ₹8,000; irrigation ₹4,000; depreciation ₹3,000; crop-loan interest ₹2,000. A1 = ₹42,000. Add leased-land rent ₹3,000 → A2 = ₹45,000. Add interest on owned fixed capital ₹1,000 → B1 = ₹46,000. Add rental value of owned land ₹5,000 → B2 = ₹51,000. Add family labour ₹6,000 → C1 = ₹52,000 and C2 = ₹57,000. C3 = ₹57,000 + ₹5,700 = ₹62,700. Reasoning: each step adds a specific imputed or paid cost.
Traps that cost marks
Mixing fixed and variable costs; omitting imputed family labour; forgetting that C3 adds 10% of C2; using C2 when a question asks for paid-out cost.
