(2) Short Run Cost II: Standard Cost Relations
Total Cost, Fixed Cost, Variable Cost, Average Variable Cost, Average Fixed Cost, Average Total Cost, Marginal Cost, Opportunity Cost, Economic Profits, Cost Curve Shapes
This presents the short run cost relations, using both the totals and the average/marinal approaches. After a brief introduction, the concepts of Total Cost, Total Fixed Cost, and Total Variable Cost are introduced, including both linear and nonlinear graphical examples. Next, the same is done with Average Total Cost, Average Fixed Cost, Average Variable Cost, and Marginal Cost. The link between production and cost is reviewed next, with emphasis on the point that the shape of the production function determines the shape of the cost function.
