A production externality occurs when the manufacturing or industrial processes of a firm unintentionally affect third parties who are not involved in the economic transaction. These externalities can be either positive or negative but are typically associated with negative impacts such as environmental pollution.
Definition of Production Externality
A production externality is a side effect or consequence of industrial or commercial activity that affects other parties without being reflected in the cost of the goods or services involved. These side effects can include pollution, noise, and other forms of environmental degradation.
Types of Production Externalities
There are two primary types of production externalities:
- Negative Externalities: These occur when the side effects of production impose costs on third parties. For example, pollution from a factory can harm local water supplies and ecosystems.
- Positive Externalities: Although rarer, these occur when production has beneficial side effects on society. For instance, a company that plants trees for lumber might improve the environment and air quality.
Measurement of Production Externalities
Measuring production externalities is a complex task that often involves economic valuation techniques and environmental impact assessments.
Economic Valuation Techniques
- Cost-Benefit Analysis (CBA): This method evaluates the total costs and benefits associated with the externality.
- Willingness to Pay (WTP): Surveys and market data can determine how much people are willing to pay to avoid negative externalities.
- Damage Cost Approach: This approach quantifies the costs of the damage caused by the externalities, such as healthcare costs related to pollution.
Environmental Impact Assessments (EIA)
An EIA is a process that evaluates the likely environmental impacts of a proposed project or development. It considers both the immediate and long-term effects on the environment.
Examples of Production Externalities
Industrial Pollution
Factories often emit pollutants into the air and water, leading to health problems for nearby residents and damage to wildlife habitats.
Noise Pollution
Manufacturing plants and construction projects can produce significant noise, affecting the quality of life for nearby communities.
Waste Management
Improper disposal of industrial waste can lead to soil contamination and negatively impact agricultural productivity.
Historical Context and Applicability
Historical Examples
- The Great Smog of London (1952): Industrial pollution combined with weather conditions led to severe air quality issues, resulting in thousands of deaths.
- Minamata Disease (1956): Industrial waste from a chemical factory caused mercury poisoning in Japan, affecting thousands of people and marine life.
Modern-Day Relevance
Production externalities remain highly relevant in today’s industrialized world. Governments and organizations are increasingly focusing on sustainable practices to mitigate these externalities.
Comparisons and Related Terms
Negative Externality
A negative externality is a broader term that encompasses any adverse side effects from economic activities, not just production.
Market Failure
Production externalities often lead to market failures where the true costs of production are not reflected in the market price of goods.
Pigovian Tax
A Pigovian tax is a tax imposed on activities that generate negative externalities, designed to correct market outcomes.

Summary
Production externalities are significant by-products of industrial activities that affect third parties, often leading to environmental and social costs. Understanding and mitigating these externalities is crucial for sustainable development and market efficiency.
