    Study Notes

    Cost Analysis

    • Cost analysis examines the relationship between costs and production criteria, like output size, operational scale, and factor prices.
    • It considers the financial aspects of production alongside the physical aspects.

    Cost Concepts

    • Accounting Cost: These are actual costs recorded in accounts. Examples include wages, rent, raw material prices, and utilities. Also called explicit costs.
    • Economic Cost: This includes implicit costs (the opportunity cost of resources used in the business) in addition to explicit costs.
      • Normal return on money capital invested by the business owner.
      • Wages/salaries that could have been earned elsewhere for the entrepreneur's services.
      • Economic Cost = Accounting Cost + Implicit Cost
    • Outlay Costs: These involve actual expenditure of funds. Examples are wages, rent, and interest. They are recorded in the books of accounts.
    • Opportunity Costs: The potential return from the next-best alternative use of resources. Not recorded in accounts. Crucial for long-term cost calculations (e.g., higher education calculations).
    • Direct Costs: Readily identified and traceable to a specific product/operation/plant (e.g., manufacturing costs to a product line).
    • Indirect Costs: Less traceable or readily identified (e.g., electricity, gatekeeper salary); however, they have a functional relationship to production.

    Accounting Costs

    • Costs actually incurred and recorded in a firm's accounts.
    • Examples include wages, rent, raw materials, and utility expenses.

    Economic Costs

    • Include accounting costs plus implicit costs (what the resources could have earned elsewhere).

    Outlay Costs

    • Costs involving actual spending.
    • Recorded as financial expenditures in the firm's accounts. (i.e. an explicit cost).

    Opportunity Cost

    • Value of the next-best alternative foregone.
    • Important in long-term decisions/cost calculations and not recorded in accounts.

    Direct and Indirect Costs

    • Direct Costs: Directly assignable to a specific product.
    • Indirect Costs: Not directly assignable to a product or service.

    Fixed Costs & Variable Costs

    • Fixed Costs: Remain constant regardless of output level (e.g., rent, interest). Cannot be avoided by shutting down temporarily.
    • Variable Costs: Vary directly with output (e.g., raw materials, wages). Can be avoided with a temporary plant shutdown.

    Cost Function

    • Mathematical relationship between a product's cost and its determinants (e.g., quantity produced, technology, factor prices, capital).

      • C = f(Q, T, P₁, K), where:
      • C = Total Cost
      • Q = Quantity (Output)
      • T = Technology
      • p = Factor Prices
      • K = Capital

    Short Run Costs

    • Fixed Cost (FC): Independent of output; incurred even if production stops temporarily. (e.g. contractual rent).
    • Variable Cost (VC): Vary with output level (e.g., labor wages, materials). Can be avoided if production ceases.
    • Total Cost (TC): Sum of Fixed and Variable Costs: TC = TFC + TVC

    Short Run Average Costs

    • Average Fixed Cost (AFC): Total Fixed Cost divided by Output; decreases as output rises.
    • Average Variable Cost (AVC): Total Variable Cost divided by Output; normally decreases up to normal capacity and rises beyond.
    • Average Total Cost (ATC): Total Cost divided by Output; U-shaped curve, with the ideal minimum point. ATC = AFC+AVC

    Short Run Marginal Cost (MC)

    • Additional cost to produce one more unit of output. MC = ΔTC/ΔQ. U-shaped curve, with the ideal minimum point.

    Long Run Costs

    • Long Run Average Cost Curve (LRAC): Envelops short-run average cost curves; reflects economies and diseconomies of scale. U-shaped.
      • Economies of Scale: Decreasing average cost as output increases.
      • Diseconomies of Scale: Increasing average cost as output increases.

    MC relationship to AC

    • When MC is below AC, average cost is falling.
    • When MC is above AC, average cost is rising.
    • When MC intersects AC, AC is at its minimum point.

    • Q6: What is the cost of one thing in terms of the alternative given up? (Opportunity Cost)
    • Q7: What cost concept is closely related to Marginal Cost? (Variable Cost)
    • Q8: When Average Cost is rising, which cost must be rising? (Marginal Cost)
    • Q9: What is an example of an "Explicit Cost"? (Payment of wages)
    • Q10: Which is an example of an Implicit Cost? (Interest that could have been earned)
    • Q11: What is the definition of Marginal Cost? (Change in total cost due to a 1-unit change in output).
    • Q12: For what MC and AC relation will Average Cost be falling? (If MC < AC)
    • Q13: Relationship between ATC, AFC and AVC? (ATC = AFC + AVC)
    • Q14: What is not a determinant of the firm's cost function? (Price of outputs)
    • Q15: What formula is true between Total Cost (TC), Total Fixed Cost (TFC), and Total Variable Cost (TVC)? (TC = TFC + TVC)
    • Q16: If output increases in the short run, what happens to total costs? (Increases, due to increase in both Fixed and Variable Costs)
    • Q17: What is false concerning LRAC? (It represents the least cost combination for producing each level of Output)
    • Q18: What is the reason behind the negatively sloped portion of the LRAC? (Economies of Scale)
    • Q19: What is behind the positively sloped part of the LRAC? (Diseconomies of Scale)
    • Q20: A firm's ATC at 5 units is Rs.300 and Rs.320 at 6 units. What is the MC for the 6th unit? ( Rs.20)
    • Q21: A firm producing 7 units has an ATC of 150 and Fixed costs of 350. What is Variable Cost per unit? (Rs.100).
    • Q22: A firm's variable cost at 5 units is Rs.1000, and fixed cost is Rs.400. What's the ATC at 5 units? (Rs.280)
