Study Notes
Babel's Production Function
- Babel's production function indicates the relationship between the quantity of labor (workers) and the output of bricks laid.
- Key data points:
- 0 workers produce 0 bricks
- 1 worker produces 4 bricks
- 2 workers produce 7 bricks
- 3 workers produce 9 bricks
- 4 workers produce 10 bricks
- Marginal product of labor decreases as more workers are hired:
- From 1 to 2 workers: 4 additional bricks
- From 2 to 3 workers: 3 additional bricks
- From 3 to 4 workers: 1 additional brick
Earl's Food Trailer Business
- Earl's production function details the output of cupcakes based on the number of workers hired.
- Key data points:
- 0 workers produce 0 cupcakes
- 1 worker produces 6 dozens
- 2 workers produce 15 dozens
- 3 workers produce 24 dozens
- 4 workers produce 27 dozens
- 5 workers produce 30 dozens (maximum)
- Total cost is influenced by two factors:
- Fixed cost of parking ($40 daily)
- Variable cost of labor ($80 per worker per day)
Ralph's Chicken Processing Plant
- Ralph's total cost function correlates to the output of chickens processed.
- Fixed cost is determined to be $800.
- At a production quantity of 3000 chickens, 6 workers are employed, calculated as:
- Total Cost = Fixed Cost + Variable Cost
- $1400 = $800 + $100 × number of workers
- Total cost increases more rapidly as output rises due to diminishing returns to labor.
Costs of Manufacturing at Everything Looks Like a Nail, Inc.
- Fixed Costs:
- Lease on the building
- Industrial equipment costs
- Interest on current debt
- Liability insurance costs
- Annual salaries of top management
- Variable Costs:
- Postage and packaging costs
- Cost of wood used in manufacturing
- Cost of metal used in manufacturing
Understanding Costs
- Variable costs rise with increased production, illustrating diminishing marginal returns.
- Fixed costs remain constant regardless of output, not changing with production levels.
Cost Classifications
- Marginal cost defined as the change in total cost per change in output (ΔTC/ΔQ).
- Average variable cost calculated as total variable cost divided by quantity (VC/Q).
- Average total cost is derived from total cost divided by quantity produced (TC/Q).
Short-Run Cost Curves
- Assessing cost curves:
- Graph A is invalid
- Graph B is valid
- Graph C is invalid
- Graph D is invalid
- Graph E is invalid
- Graph F is valid
True/False Cost Statements
- Costs can be classified as fixed or variable.
- Average fixed cost decreases over time, whereas average variable cost can fluctuate.
- Average total cost (ATC) always exceeds average variable cost (AVC) in the short run.
Cost Interactions in Firm Dynamics
- Long-run average total cost (LRATC) curve showcases economies of scale, constant returns to scale, and diseconomies of scale at different production levels.
- Economies of scale occur up to a certain output level, followed by a phase of constant returns and eventually diseconomies.
Long Run vs. Short Run
- The long run allows for all inputs to be adjusted, contrasting the short run's fixed input limitations.
- Key insights on cost dynamics guide firms in optimizing production strategies and resource allocations.
