Study Notes
Cost Structure and Break-even Point
-
Total cost is comprised of fixed cost and variable cost.
-
Variable costs are directly related to the volume produced.
- An increase in production volume leads to an increase in total variable costs.
- The relationship between variable costs and volume is not linear due to discounts on purchases and efficiency increases.
- High variable cost incidence makes the total variable cost curve steeper.
-
Fixed costs are independent of the production volume and determined by the production capacity available.
- Fixed costs are affected by production capacity limits.
- Fixed costs are more or less constant.
-
Cost structures dominated by variable costs are considered flexible due to their ability to adapt to changing volumes.
-
Cost structures dominated by fixed costs are considered rigid due to their difficulty in adapting to changing volumes, posing higher risk.
-
Operating elasticity refers to the extent to which demand responds to price changes.
- Higher elasticity means lower risk.
- Operating risk can amplify losses below the Break-Even Point (BEP) but also amplify profits above the BEP.
-
Startups tend to have higher fixed cost incidence leading to a higher break-even point (BEP) and quicker reaching of the BEP.
- However, the profits per unit are slow.
- Startups are encouraged to have a higher incidence of variable costs to reach the BEP quickly.
Volume Economies & Scale Economies
-
The company's cost structure influences its growth potential.
-
Maximum Production Capacity (MPC): Represents the maximum number of units a company can produce within a given time period.
-
Current Production Capacity (CPC): Represents the number of units a company actually produces within a given time period.
-
The degree of utilization is the ratio of CPC to MPC.
-
Different methods quantify capacity depending on the company type:
- Manufacturing firms measure capacity based on the number of units produced (e.g., shoes, cars).
- Retail companies measure capacity based on the size of their store (e.g., supermarkets) which translates to more shelves and goods displayed.
- Airline companies measure capacity based on the number of available seats and miles flown.
-
Economies of scale arise when average unit costs decrease with increased output.
- For example, the average unit cost per audience member in a smaller theatre is higher than a larger one with the same utilization rate.
-
Economies of scale occur due to:
- Indivisibility of inputs: Certain inputs cannot be divided into smaller units (e.g., teachers, desks, computers).
- Bargaining power: Higher production volumes offer suppliers price discounts.
- Greater technological efficiency: Some production plants become more efficient as their scale increases.
- Specialization: Larger companies can specialize resources for specific projects.
- Geometric properties of containers: The increase in capacity grows faster than the increase in costs, resulting in decreasing average unit costs.
-
Economies of scale follow a U-shaped curve:
- Initially, increasing capacity leads to lower average unit costs.
- As capacity surpasses a certain point, operational complexity increases, leading to higher average unit costs and diseconomies of scale.
Scope Economies & Learning Economies
-
Scope economies refer to cost advantages gained by expanding the variety of goods and services produced.
-
Volume and scale economies refer to growth based on a single product, while scope economies achieve growth through a mix of products.
-
Diversification can happen at different levels:
- Single and dominant business: Focuses on one product (e.g., Walmart).
- Related business: Expanding product line within the same industry (e.g., Leather belts to leather bags).
- Unrelated business: Operating in different industries unrelated to the core business (e.g., Disney).
- Conglomerate: a large corporation composed of independent and unrelated businesses (e.g., Amazon).
-
Scope economies reduce costs by utilizing underutilized resources across different products.
- Examples include Armani leveraging the brand across different sub-labels (Giorgio Armani, Armani casa, Emporio Armani) and Poste Italiane offering postal services, retail, and financial products.
-
Phenomena related to scope economies:
- Two-sided markets: Integration of goods that are complementary or correlated on both the demand and supply sides (e.g., Google search engine and advertising services).
- Cross-subsidization: Pricing one product above its market value to cover losses on another product priced below market value.
-
Learning economies occur when unit costs decrease and output quality improves over time as experience accumulates.
-
Learning economies are measured based on cumulative production volume and are calculated each time production doubles.
