Study Notes
Production Concepts
- Fixed resources, including technology and capital, are constants in production, while variable factors like labor can be adjusted in the short run to increase output.
- In the long run, firms can vary all resources, leading to changes in plant size.
- Cost differentiation exists between fixed and variable costs depending on the time frame; all fixed costs become variable in the long run.
Short Run Production
- Total Product (TP): Represents the total quantity of a good produced over a specified period and reflects how output increases with labor.
- Production Function: Illustrates the relationship between input quantities and output levels—important for understanding marginal and average products.
- Marginal Product of Labor (MPL): Measures the change in total product resulting from hiring an additional worker, calculated as ΔQ/ΔL.
- Average Product (AP): Indicates the total product per unit of labor; it is synonymous with productivity and calculated as TP/L.
Marginal Returns
- Increasing Marginal Returns: Occurs when MPL of a new worker exceeds that of the previous worker, often stemming from specialization and labor division.
- Decreasing Marginal Returns: Happens when MPL of an additional worker is less than that of the last, due to limited resources and workspace efficiency.
Short Run Cost Analysis
- Total Fixed Costs (TFC) remain unchanged regardless of output, while Total Cost (TC) is shaped by Total Variable Costs (TVC).
- Relationship between Marginal Cost (MC) and Average Total Cost (ATC):
- Average total cost falls when MC is below it and rises when MC surpasses it.
- Minimum points for ATC and AVC occur where they intersect with the MC curve.
Long Run Cost Curves
- Long-run average-total-cost (ATC) curve is flatter than the short-run. This reflects the ability of firms to adjust all resources over time.
- Economies of Scale: Long-run ATC declines as output increases.
- Constant Returns to Scale: Long-run ATC remains unchanged with increased output.
- Diseconomies of Scale: Long-run ATC rises as output increases.
Profit Concepts
- Profit Calculation: Profit equals total revenue (TR) minus total cost (TC).
- Economic Profit: Total revenue minus both explicit and implicit costs.
- Accounting Profit: Total revenue minus only explicit costs.
Cost Types
- Explicit Costs: Cash payments made for inputs, e.g. wages and rent.
- Implicit Costs: Opportunity costs of resources owned by the firm, e.g., the earnings foregone by using owned resources.
Revenue Concepts
- Total Revenue (TR): The income received from sales, calculated as TR = Price × Quantity.
- Marginal Revenue (MR): The revenue increase from one additional unit produced, calculated as ΔTR/ΔQ.
- Average Revenue (AR): Average revenue received per unit sold, computed as TR/Quantity sold.
