Study Notes
Technology in Economics
- Technology refers to processes firms utilize to convert inputs into goods and services.
- Technological change enhances a firm's ability to produce more output with existing input amounts.
Short Run vs. Long Run
- Short Run: A timeframe where at least one input is fixed and cannot be changed.
- Long Run: A sufficient period allowing full variations in all inputs, adoption of new technology, and adjustments to plant size.
Costs in Production
- Total Cost (TC) consists of both fixed and variable costs (TC = FC + VC).
- Fixed Costs (FC) remain constant regardless of production levels.
- Variable Costs (VC) fluctuate with the quantity of output produced.
Implicit vs. Explicit Costs
- Opportunity Cost represents the value of the next best alternative forgone.
- Explicit Costs involve direct monetary expenditures.
- Implicit Costs reflect non-monetary, opportunity costs.
Production Function
- The production function links input quantities to the maximum achievable output.
Marginal Product of Labor (MPL) & Average Product of Labor (APL)
- Marginal Product of Labor indicates the additional output from hiring one more worker.
- The Law of Diminishing Returns asserts that adding more of a variable input, while holding fixed input constant, eventually leads to decreased marginal returns.
- Average Product of Labor is calculated by dividing total output by the number of workers employed.
Marginal Cost (MC)
- Marginal Cost signifies the change in total cost resulting from producing one more unit of output, calculated as MC = ΔTC/ΔQ.
Average Cost Curves
- Average Total Cost (ATC) is calculated as total cost divided by output quantity (ATC = TC/Q).
- Average Fixed Cost (AFC) and Average Variable Cost (AVC) represent fixed and variable costs per unit of output respectively.
Graphing Cost Curves
- All cost curves (MC, ATC, AVC) are U-shaped.
- The marginal cost curve intersects the AVC and ATC at their minimum points.
- As output increases, AFC decreases, and the gap between ATC and AVC shrinks.
Long-Run Costs
- The Long-Run Average Cost Curve shows the minimal cost of producing a given output level when no inputs are fixed.
- Economies of Scale occur when long-run average costs decline with increased production.
- Constant Returns to Scale maintain stable long-run average costs as output rises.
- Minimum Efficient Scale denotes the output level where economies of scale are maximized.
- Diseconomies of Scale lead to higher long-run average costs as production scales up.
