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.
