      • The average total cost of producing each of 40 coffee cups is 320$ / 40 = 8$ per coffee. The average cost curve is generally a U shaped curve, where the Average Total Cost is relatively high, because at a low level of outputs total costs are more than the fixed costs.
  1. Calculate long run total cost. Identify economies of scale, diseconomies of scale, and constant returns to scale. Interpret graphs of long-run average cost curves and short-run average cost curves. Analyze cost and production in the long run and short run. The long run is the period of time when all costs are variable.

    Because the short run marginal cost curve is sloped like this, mathematically the average cost curve will be U shaped. Initially, average costs fall. But, when marginal cost is above the average cost, then average cost starts to rise. Marginal cost always passes through the lowest point of the average cost curve.

    ATC (Average Total Cost) = Total Cost / quantity
    AVC (Average Variable Cost) = Variable cost / Quantity
    AFC (Average Fixed Cost) = Fixed cost / Quantity

    The long-run cost curves are u shaped for different reasons. It is due to economies of scale and diseconomies of scale. If a firm has high fixed costs, increasing output will lead to lower average costs. However, after a certain output, a firm may experience diseconomies of scale. This occurs where increased output leads to higher average costs. Fo...

  2. Aug 16, 2023 · Average Costs are the per unit costs which explain the relationship between the cost and output in a realistic manner. These per-unit costs are obtained from Total Fixed Cost, Total Variable Cost, and Total Cost. The three different types of per-unit costs are as follows: 1. Average Fixed Cost (AFC):

  3. A graph of the various level curves of a function is called a contour map. Example: Making a Contour Map Given the function [latex]f\,(x,\ y)=\sqrt{8+8x-4y-4x^{2}-y^{2}}[/latex], find the level curve corresponding to [latex]c=0[/latex].

  4. The five different short-run average cost (SRAC) curves each represents a different level of fixed costs, from the low level of fixed costs at SRAC 1 to the high level of fixed costs at SRAC 5. Other SRAC curves, not shown in the diagram, lie between the ones that are shown here.

  5. Average Costs and Curves | Microeconomics. Learning Objectives. Describe and calculate average total costs and average variable costs. Calculate and graph marginal cost. Analyze the relationship between marginal and average costs. The cost of producing a firm’s output depends on how much labor and capital the firm uses.

  6. Figure 8.5 illustrates three situations: (a) where price intersects marginal cost at a level above the average cost curve, (b) where price intersects marginal cost at a level equal to the average cost curve, and (c) where price intersects marginal cost at a level below the average cost curve.
