Question

Describe three consumption activities that create external costs.

Short answer

Smoking cigarettes, using private vehicles, and excessive alcohol consumption create external costs.

Step-by-step solution

- Define Consumption Activities

Consumption activities are actions undertaken by individuals or households that lead to the use of goods and services. These activities can sometimes result in costs or benefits that affect third parties who are not directly involved in the activity.

- Explain External Costs

External costs (or negative externalities) occur when the consumption of a good or service imposes a cost on third parties. These costs are not reflected in the market price of the good or service consumed.

- Consumption Activity 1: Smoking Cigarettes

When individuals smoke cigarettes, it affects not only the smoker but also people around them through secondhand smoke. This external cost includes health impacts on non-smokers, increased healthcare costs, and reduced air quality.

- Consumption Activity 2: Using Private Vehicles

The use of private vehicles contributes to air pollution and traffic congestion. These external costs involve increased respiratory problems for the population, higher healthcare expenses, and time lost due to traffic jams.

- Consumption Activity 3: Excessive Alcohol Consumption

Excessive alcohol consumption can lead to public disturbances, increased violence, and higher law enforcement costs. These external costs affect the overall safety and well-being of the community.

Key concepts

Consumption Activities

Consumption activities are everyday actions by individuals or families involving the purchase and use of products and services. These activities might unintentionally lead to effects on other people who are not involved in the consumption act. For instance, smoking cigarettes affects not just the smoker but also those around them due to secondhand smoke. In simpler terms, consumption activities describe how people use various goods, like cars, or services, like public transport, in their daily lives.

Negative Externalities

Negative externalities occur when a consumption activity imposes adverse effects on third parties. These harmful side effects are not included in the price of the product or service. For example, when driving a car, the driver may enjoy the convenience, but the tailpipe emissions contribute to air pollution, a detriment to the health of others. Negative externalities are often invisible costs to society. They impact people even if they are not consuming the products causing the harm. Hence, society might bear extra costs like healthcare services or environmental cleanup.

Public Health Impacts

Public health impacts refer to the effects that consumption activities have on the health and well-being of the communal population. For instance, smoking in public places can lead to secondhand smoke inhalation by non-smokers, causing respiratory issues and other health problems. Another example is air pollution from vehicles, which can increase asthma and other respiratory diseases among the population. These health impacts create a burden on the healthcare system, leading to higher medical costs and additional strain on public health resources.

Air Pollution

Air pollution is the contamination of the air due to harmful substances like exhaust gases from vehicles or industrial emissions. When people use private vehicles extensively, they contribute to a rise in harmful pollutants such as carbon monoxide and nitrogen oxides in the air. This has several negative effects:

• Health problems like lung diseases and heart conditions in humans.
• Damage to the environment, including harm to wildlife and ecosystems.
• Reduced quality of life due to smog and decreased visibility.

Understanding air pollution's impact helps in finding ways to reduce it, such as using public transportation or cleaner energy sources.

Law Enforcement Costs

Law enforcement costs are the expenses associated with maintaining public order and safety, often heightened due to certain consumption activities. For instance, excessive alcohol consumption can lead to public disturbances like fights or vandalism. This necessitates a greater law enforcement presence, leading to increased costs for policing and emergency services. These costs may also cover preventive measures, legal proceedings, and incarceration. Law enforcement costs are not only financial but also affect the social fabric by diverting resources from other important community needs.
