Study Notes

Chapter 6: A Firm's Production Decisions and Costs in the Short Run

This chapter explores a firm's production decisions and costs in a short-run context.
Firms are defined as business organizations that hire and organize production factors to sell goods and services.
Different types of business organizations exist, such as sole proprietorships, partnerships, corporations, state-owned enterprises, and non-profit organizations.
Production is the activity of a business using inputs (e.g., sand, gravel, cement, water, machinery, and labor) to achieve output (e.g., concrete). Costs represent the payments for these inputs.

Learning Objectives

Explain what a firm is and list different firm types.
Describe how economists and accountants measure costs differently and differentiate between their profit views.
Explain the relationship between productivity and costs.
Demonstrate the difference between fixed and variable costs.
List and graph seven specific cost definitions used by economists.
Explain increasing productivity and cutting costs.

Explicit and Implicit Costs

Explicit costs: Actual monetary payments made to non-owners for resources.
Implicit costs: The opportunity cost of using an owner's resources without paying them out in cash.

Profit

Accounting profit: Total revenue minus total explicit costs.
Economic profit: Total revenue minus all costs, including explicit and implicit costs.
Normal profit: The minimum profit needed to keep an entrepreneur in a business—it's considered an implicit cost.

Theory of Production

Short run: A period where at least one input in the production process is fixed.
Total Product: The total output of any production process.
Marginal Product (MP): The increase in total product resulting from adding one more unit of input (usually labor).
Average Product (AP): Total product divided by the quantity of inputs used to generate that total product.

Division of Labor

Division of labor: Breaking the production process into specialized tasks, each performed by a different worker.
Benefits: Increased worker dexterity, efficient time use, and easier machinery specialization.
Law of Diminishing Returns: As more of a variable input is added to a fixed input, the resulting increase in output will eventually diminish.

Marginal and Variable Costs

Total Variable Cost (TVC): The total cost of all inputs that vary with the production level.
Marginal Cost (MC): The increase in total variable costs when one additional unit of output is produced.
Average Variable Cost (AVC): Total variable cost divided by total output.

Total and Average Total Costs

Total Fixed Costs (TFC): Costs that don't change with the level of output.
Average Fixed Costs (AFC): Total fixed cost divided by output.
Total Costs (TC): The sum of total fixed and total variable costs.
Average Total Costs (ATC): Total cost divided by output.

Relationship Between Cost and Product Curves

Marginal cost (MC) curve: Intersects the AVC and ATC curves at their respective minimum points.
Average fixed cost (AFC) curve: Always decreasing.
Q1: Diminishing returns point.
Q2: Most productive output point.
Q3: Economic capacity point.

Key Concepts to Remember

Implicit and explicit costs.
Normal and economic profit.
Total, average, and marginal product.
Law of diminishing returns.
Cost curves (MC, ATC, AVC, AFC).
