What is the difference between explicit costs and implicit costs?
What is the difference between explicit costs and implicit costs?
Explicit costs are out-of-pocket expenses that a firm actually pays, while implicit costs are the opportunity costs of using resources already owned by the firm.

Study Notes
Production Function
- Explains how firms convert inputs into outputs
- Determines input quantities (labor, raw materials, capital) for optimal output production
- Dictates output quantities based on demand
- Focuses on a business' productive activities, including short-run cost minimization and short-run profit maximization, and long-run profit maximization
- Determining the plant's most profitable size
- Involves choosing variable inputs to minimize total cost with fixed inputs. Examples of variable inputs are raw materials, labor, capital, etc.
Law of Diminishing Marginal Return
- Also known as the law of diminishing returns, the principle of diminishing marginal productivity and the law of variable proportions
- States that after a certain optimal capacity level, adding more of one factor of production results in smaller increases in output
- This principle stipulates that adding more of one input, holding others constant, will lead to a decrease in the incremental return.
- Understanding these stages is essential for producers to optimize their production process.
Three Stages of Production
- Increasing Returns Stage: Output increases as more units of input are added.
- Diminishing Returns Stage: Output decreases as more units of input are added.
- Negative Returns Stage: Output decreases further as more units of input are added.
Short-Run Cost Minimization
- Selecting input quantities to minimize short-run total costs
- Some factors of production are fixed within the short term
Short-Run Profit Maximization
- Occurs when marginal revenue equals marginal costs
- If marginal revenue exceeds marginal cost, production should continue for profit gains
- Point where marginal revenue equals marginal cost as long as the competitive marketplace allows a positive profit before perfect competition
Long-Run Profit Maximization
- Optimizes profits over an extended period
- Involves adjustments to all inputs. Examples include labor, capital, technology
- May involve investment in technology and innovation for greater efficiency
- Long-term changes adjust factors such as labor, capital, and technology
- Creates sustainable advantages for profit maximization
Total Variable Cost
- Cost of all variable inputs of production (e.g., raw materials, labor)
Total Fixed Cost
- Costs of fixed inputs in production (equipment, building rent)
Total Cost
- Total variable cost plus total fixed cost
Average Variable Cost
- Variable cost per unit of output
Average Fixed Cost
- Fixed cost per unit of output
Average Total Cost
- Total cost per unit of output
Marginal Cost
- Change in total cost from producing one more unit
Market Structure
- Classifies markets based on competition levels
- Helps understand the features of different markets
- Analyzes how firms compete and differentiate products
Types of Markets (Imperfect competition)
- Perfect Competition: Many buyers and sellers dealing in identical products; free entry/exit; price takers (no individual influence)
- Monopolistic Competition: Many sellers offer similar but differentiated products (i.e., brand names, quality); low barriers to entry; competitive (no single firm controls the market).
- Oligopoly: Few large firms dominate the market; significant barriers to entry; actions of one firm affect others; potential for collusion or competition
- Monopoly: Only one seller in the market; unique product with no close substitutes; high barriers to entry due to high fixed costs (or legal restrictions).
Monopsony
- A market with only one buyer
- The buyer (monopsonist) has significant power over price.
Oligopsony
- A market with only a few buyers
- The few buyers have significant power over price.
